services servi galvanosis is a pathological condition characterized by the effect of galvanic currents on the oral mucosa. the pathogenetic basis of galvanosis is the corrosion of dissimilar metal materials of dentures, caused by electrochemical processes occurring in the oral cavity [1-2]. one of the effective diagnostic tests is the removal of structures made of dissimilar metals [3]. after excluding structures made from dissimilar alloys, patients, as a rule, note a decrease or even disappearance of unpleasant sensations [4-5]. however, there are cases when a patient complains when there are dentures made of one alloy in the oral cavity (grechishnikov n.s., 2017). in this study, galvanism is a factor contributing to the development of precancerous diseases of the oral cavity [9], which is quite common in recent years, which in turn indicates the need to control the technical part of orthopedic rehabilitation. the object of the study is to substantiate an integrated approach to the diagnosis of patients with precancerous diseases of the oral mucosa against the background of galvanosis. material and research methods. we examined 150 patients with signs of galvanosis who applied to the department of therapeutic dentistry of the tgsi in the period from 2019 to 2023. to fulfill the objectives of the study, the patients who applied were examined clinically, using potentiometry, autofluorescence stomatoscopy, and also cytologically using the papanicolaou and abdullahodzhaeva-krahmalev methods. autofluorescent stomatoscopy was carried out in the department of hospital therapeutic dentistry. cytological research methods were carried out on the basis of the republican pathological anatomical center. we considered the different range of complaints noted in patients with precancerous diseases of the oral mucosa, due to the diversity of lesions, from the perspective of the patient. for example, soreness of the oral mucosa was recorded as the most common symptom, observed in 92% of patients, and many associated the feeling of pain with a burning sensation in the mouth, noted in 37% of cases. in addition, roughness of the oral mucosa, a feeling of tightness of the mucous membrane and a feeling of dryness of the oral mucosa were noted. 18% reported a feeling of awkwardness or unpleasant sensation during functional activities of the oral cavity. 9% of patients had no complaints. potentiometry confirmed the presence of microcurrents in the oral cavity in all subjects. all 150 study patients were examined for the presence of pathological fluorescence of the mucous membranes. thus, in all subjects, an increased or decreased intensity of luminescence was recorded during autofluorescent stomatoscopy. when the beam of the device was aimed at the mucous membrane in the affected area, a difference in fluorescence was noted in the form of a clear focus of hyperkeratosis https://doi.org/10.37547/ajbspi/volume03issue03-01

of erosive lesions, on the contrary, a dimming of the glow was recorded, highlighting the lesion against the background of a brighter healthy mucous membrane. thus, in patients with lp, there was a decrease in oral mucosa fluorescence in 85% of cases. in patients with veruccous leukoplakia, increased fluorescence in the form of a bright white glow was observed in 14%. in 1 patient, a heterogeneous glow with the presence of dark spots, almost black, was noted complete quenching of fluorescence against the background of a brown or red glow of the surrounding mucosa, confirmed by subsequent morphological analysis as oral cancer. analysis of research data using the abdullahodzhaevakrahmalev method showed positive results when conducting screenings in order to identify the initial stages of the development of malignancy. dispersed luminous particles were found in smears of patients with galvanosis even in the absence of clinical signs. during inflammation, alterative signs of epithelial structures gave a picture of single dsps, which gives us the opportunity to talk about the possible development of cellular atypia in the future. thus, we can judge the effectiveness of screening studies to identify precancerous diseases. using a metallographic inverted microscope and a digital camera, the image was placed on a computer, which later helped to compare the picture of the clinical and cytological examination. thus, the following data were obtained. in 1 patient, intraepithelial dsps were found in large quantities. an interesting fact was that in 65% of the studied patients, in the complete absence of cytological changes, intercellular dscs were registered; this feature suggests that chronic diseases caused by galvanism are in fact considered precancerous for good reason, due to the gradual destruction of cellular structures, and the following a stage of tissue restructuring may be dysplasia as a stage of cellular atypia. thus, we can talk about the potential risk of malignancy in the absence of necessary treatment. conclusions. dispersed luminous particles using the abdullahodzhaeva-krahmalev method were identified in galvanosis of the oral cavity, and in most cases they are multiple intercellular, which indicates the risk of developing malignant tumors of the oral cavity. using the abdullahodzhaeva-krahmalev method, a system for adequately assessing the diagnosis of precancerous diseases against the background of galvanosis has been improved. references 1. nico mm, fernandes jd, lourenço sv. oral lichen planus. an bras

that negatively affects the health of adults and children today. despite the fact that modern medicine is developing year by year, and new technologies are coming in, there are still many problems that are waiting to be solved in terms of making an accurate diagnosis of allergic diseases in patients. in the history of diagnosis of allergic diseases, in the second half of the 19th century, skin testing with extracts of potential allergenic sources began to be used [1]. in 1967, specific ige was detected in the blood serum of a patient with myeloma, and tests for in vitro diagnosis of allergic diseases began to appear. it is no exaggeration to say that a real revolution in allergology took place at the research article results of molecular diagnostics of allergens causing allergy

of traditional allergen extracts, which are a modern method of determining sensitization. the molecular components used today are purified or recombinant proteins, which provide a higher level of standardization than allergen extracts and allow the detection of specific iges with high sensitivity [4]. this study was conducted in order to determine which allergenic molecules are sensitive to

oxidationreduction conditions, their reaction and solubility of chemical components. soil air provides oxygen to plant roots and soil-dwelling organisms, and is also an important factor in plant carbon nutrition. note that more than half of the carbon dioxide used for crop production is provided by the plant from the soil. soil air composition varies significantly over time and across the soil profile, depending on biological activity, hydrothermal conditions, gas adsorption, soil solids, and the intensity of gas exchange between soil and atmosphere. with normal gas exchange between the soil and atmospheric air, as a number of authors have noted, the concentration of co2 in the upper horizon layer of the soil under various crops usually does not exceed 1-2%. soil temperature and humidity have a strong influence on the intensity of gas exchange and the composition of soil air. it should be noted that the gas regime of the saline soils of our republic and its changes during the

services servi irrigation period and the implementation of melioration measures have not been sufficiently studied. there are some data in the literature describing soil air composition in irrigated light gray soils exposed to secondary salinity. as noted by a.n. sokolovsky, changes in the composition of soil air strongly affect the activity of microorganisms and the dynamics of soil processes, as well as soil fertility. due to excessive water saturation, plants begin to suffer from lack of air in the soil. thus, in cotton plants, when overwatered, the active roots die, they are renewed only after the soil moisture decreases. according to a.g. bondarev's observations, under conditions of normal gas exchange of the soil profile, the amount of oxygen decreases and co2 increases, but their sum is close to the sum of these gases in the atmosphere, i.e. around 21%. research conducted by a.v. veretennikov showed that in june, the irrigation water level is usually close to the soil surface, and unfavorable weather conditions usually occur in these months, because the roots of stem plants are less supplied with oxygen. . during long-term flooding, due to the slow dissolution of oxygen in the water and its increase, pine and spruce roots experience a lack of oxygen at certain times of the year. this is confirmed by the facts of mass death of roots. in addition, he notes that in may, the amount of carbon dioxide in the soil water ranged from 18 to 40 mg / l. later, a gradual increase in the amount of carbon dioxide was observed during the growing season: in june up to 79, in july up to 80, and in august up to 131 mg / l. at the beginning of september, the amount of carbon dioxide decreased to 62 mg/l, and in october to 42 mg/l. the study of the dynamics of o2 and co2 in the soil air of gray soils with a light mechanical composition during the experiments showed that the concentration of co2 and the intensity of o2 absorption directly depend on the mineralization of irrigation water. it can be seen from the presented data (table 1) that in the control option, before the first watering and at the end of the growing season, the amount of o2 in the upper layers of the studied soils is almost unchanged and slightly reduced. the amount of carbon dioxide is 0.3-0.6%, and their amount increases with depth. in the third year of irrigation with mineralized water, the amount of oxygen in the upper layers of the soil (0-45 cm) is 18.5%, in the depth it decreases to 17.7%, and the amount of carbon dioxide increases from 1.2% to 2.2%. the determinations made after the first watering revealed a significant decrease in oxygen in the soil throughout the profile, but the most important are its lower layers. the amount of carbon dioxide has increased dramatically. however, despite this, by the beginning of the second growing season, the oxygen content is usually returned to the original level with a sharp decrease in carbon dioxide in the soil. a similar situation continues until the end of the irrigation period. at the same time, the amount of carbon dioxide is slightly higher compared to the original. it

services servi can be seen that this process is associated with the increase in the intensity of soil respiration with the release of carbon dioxide due to irrigation and the activation of biological processes. by summer, as the soil warms (up to 26-28c) and dries up, as well as the growth period of cotton grows, a further increase in co2 occurs in the studied layers. it is clear that irrigation

epidemiological features of these pathologies in different regions and population groups are essential steps in optimizing medical care, developing effective preventive measures, and rationally allocating healthcare resources. only a comprehensive approach that considers the epidemiological, clinical, and social aspects of this problem will achieve significant progress in the field of neonatal surgery. the established increase in the incidence of surgical diseases in newborns necessitates the justification of modern, cost-effective approaches to organizing medical care, treatment methods, and rehabilitation of patients. the large number and variety of surgical operations on the digestive system performed on newborns in the first days of life prompt the search for ways to

a fundamental aspect of human physiology, particularly relevant in the context of athletes, fitness enthusiasts, and individuals engaged in regular physical activity. understanding how the body responds and adapts to various forms of physical stress is of paramount importance for optimizing performance, preventing injuries, and promoting overall health and well-being. this essay explores the significance of studying adaptation to physical load and its implications for athletic performance, injury prevention, personalized training programs, recovery optimization, health and wellbeing, and scientific advancements. performance enhancement one of the primary reasons for studying adaptation to physical load is its direct impact on athletic performance. by comprehending the physiological responses to different training stimuli, athletes and coaches can design training programs that strategically manipulate variables such as intensity, volume, and frequency to elicit specific adaptations. this understanding allows for the optimization of training regimens to promote favorable changes in muscular strength, endurance, power, and aerobic capacity, ultimately leading to enhanced athletic performance. injury prevention studying adaptation to physical load is crucial for designing training programs that minimize the risk of injuries. by gradually increasing the intensity and volume of training in a structured manner, individuals can allow their bodies to adapt and become more resilient. this approach reduces the likelihood of overuse injuries and musculoskeletal imbalances, thus promoting long-term athletic development and sustainability in physical activity. personalized training programs the significance of studying adaptation to physical load lies in its ability to inform the development of personalized training programs. every individual responds differently to training stimuli due to variations in genetics, training history, and physiological characteristics. by understanding how individuals adapt to physical stress, coaches and sports scientists can tailor training programs to suit an individual's specific needs, optimizing training effectiveness while minimizing the risk of overtraining or undertraining. recovery optimization understanding the adaptive responses to physical load is essential for optimizing recovery strategies. effective recovery is crucial for facilitating the adaptation process and minimizing the risk of overreaching or overtraining syndrome. by recognizing the time course of adaptation and recovery, athletes can implement targeted recovery interventions such as nutrition, sleep, and active recovery techniques to https://doi.org/10.37547/ajbspi/volume03issue03-01

activity, leading to various structural, functional, and biochemical changes. in the context of athletes, understanding the mechanisms of physiological adaptation is crucial for optimizing training programs, enhancing performance, and preventing injuries. this essay explores the key mechanisms underlying physiological adaptation in athletes, including muscular adaptations, cardiovascular adaptations, metabolic adaptations, and neuroendocrine adaptations. muscular adaptations one of the primary mechanisms of physiological adaptation in athletes is the development of muscular strength, power, and endurance. resistance training and high-intensity activities stimulate muscle fibers to https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

force-generating capacity. additionally, regular physical activity promotes improvements in neuromuscular coordination and motor unit recruitment, leading to enhanced motor skills and movement efficiency. these adaptations are mediated by molecular signaling pathways such as mtor (mechanistic target of rapamycin) and ampk (adenosine monophosphate-activated protein kinase), which regulate protein synthesis and mitochondrial biogenesis, respectively. cardiovascular adaptations athletes also undergo significant cardiovascular adaptations in response to endurance training and aerobic activities. prolonged exercise leads to increased cardiac output, stroke volume, and capillarization of skeletal muscle, facilitating greater oxygen delivery to working muscles. this is accompanied by structural changes in the heart, such as eccentric hypertrophy of the left ventricle and enhanced myocardial contractility. these adaptations are mediated by physiological stimuli such as shear stress, hypoxia, and sympathetic activation, which trigger molecular pathways involving nitric oxide, vascular endothelial growth factor (vegf), and endothelin-1. metabolic adaptations another critical mechanism of physiological adaptation in athletes involves metabolic changes that optimize energy production and utilization. endurance training induces mitochondrial biogenesis and oxidative enzyme upregulation in skeletal muscle, enhancing the capacity for aerobic metabolism and fatty acid oxidation. concurrently, anaerobic activities promote adaptations such as increased glycolytic enzyme activity and improved buffering capacity to sustain high-intensity efforts. these metabolic adaptations are regulated by transcriptional coactivators like pgc-1α (peroxisome proliferator-activated receptor gamma coactivator 1-alpha) and metabolic sensors such as ampk, which coordinate cellular energy homeostasis and substrate utilization. neuroendocrine adaptations the neuroendocrine system plays a pivotal role in mediating physiological adaptations to exercise in athletes. intense training stimulates the release of anabolic hormones such as testosterone, growth hormone, and insulin-like growth factor-1 (igf-1), promoting muscle protein synthesis and tissue repair. conversely, endurance exercise elicits the secretion of cortisol and catecholamines, which mobilize energy substrates and facilitate cardiovascular function. these hormonal responses are modulated by the hypothalamic-pituitary-adrenal (hpa) axis and the hypothalamic-pituitary-gonadal (hpg) axis, orchestrating adaptive changes in metabolism, tissue remodeling, and stress resilience. in essence, the mechanisms of physiological adaptation in athletes encompass a wide array of structural, functional, and biochemical responses that https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03 issue

urgent problem is the creation and introduction into production of biostimulants intended for inclusion in mixed feeds and diets that have a beneficial effect on metabolism, animal productivity, the quality and safety of products of animal origin. purpose and objectives of the research. the main goal of the study was to study biostimulants on milk production and the state of the immune system in cattle. to achieve the goal, the following tasks were set: 1. determine the effect of a feed biostimulant on the milk productivity of cows and the quality of raw milk. 2. study the biochemical parameters of cows’ blood when using a biostimulator. 3. assess the economic efficiency of introducing biostimulants into the diets of highly productive cows. methods research was carried out using clinical-physiological, microbiological, veterinary-sanitary, zootechnical and mathematical methods. the effect of biostimulants in different doses on metabolic processes, productivity and quality of milk of cows was studied. the research was carried out on 32 dairy cows in the zangiota district of the tashkent region in 2021. animals in the control and experimental groups received a diet consisting of wheat straw (0.6 kg), corn silage (23.0 kg), wheat haylage (50.0 kg), complete feed (14.58 kg), optigen (0 .05 kg) and alfalfa haylage (6.50 kg). the animals of the experimental groups received a mineral feed regulator in a dose of 300 g daily in addition to the main diet (br) as part of a complete feed. results and discussion https://doi.org/10.37547/ajbspi/volume03issue03-01

daily records during each milking. the study period was divided into 5 additional periods of 20 days each. in general, research results have shown that the trend in the level of milk productivity is increasing. the subsequent increase is probably associated with the stabilization of the energy balance in the body of dairy cows. with the introduction of biostimulants in milk it increases, however, we did not observe an excess of the upper limit of the norm. in addition, it was found that in accordance with the selected analysis criteria in the studied population of animals, in 17.05% of cows the biostimulant corresponded to optimal values. the biostimulant tended to decrease as the milk productivity of animals increased, and increased as soon as the milk productivity of animals began to decline in the dynamics of milking days. the economic efficiency of feeding a biostimulant feed regulator in the diet of cows is the calculation of the economic feasibility of its use. the main indicators in the economic assessment were: the cost of feed, average daily milk yield and the market price of milk. conclusion according to the task, further research was aimed at studying the effect of biostimulants on the productivity and metabolism of high-yielding cows. it is known that feeding, and as a consequence, the introduction of biostimulants, is one of the leading factors in ensuring high productivity of dairy livestock. this is explained by the fact that during lactation the animal’s body is in a state of increased functional activity; complex processes of fermentation of feed through a huge number of bacteria, fungi, protozoa, as well as the absorption of nutrients and the synthesis of new ones, take place in the proventriculus. all this provides the animal with the necessary energy and nutrients, affects the physiological processes occurring in the body, which in turn helps to enhance metabolic processes, productive and reproductive phenomena. an important point in these processes is the ability to control rumen digestion by adjusting the diet through the use of various biostimulants. references 1. абилов, а.и. влияние теплового стресса на воспроизводительную

servi abstract effects of alcohol metabolites, mainly acetaldehyde, on the heart. disturbances in metabolism and electrolyte imbalance lead to arrhythmias and disturbances in the functional activity of the heart. acetaldehyde disrupts the synthesis of several compounds and increases the synthesis of inflammatory cytokines and leads to the development of an autoimmune process. the weight of the heart is 500-550 gr. and it is observed that it is filled with fat. when the heart is placed on the operating table, it is diffuse, similar to infectious myocarditis, and the heart is red or purple in

remain dominant in economically developed countries. cardiomyopathies are an important part of cardiovascular diseases with their severe course and numerous life-threatening complications [3,5]. there are several types of cardiomyopathies, one of which is alcoholic cardiomyopathy. the relevance of alcoholic cmp is determined by its relatively frequent occurrence, development along with other heart diseases, and in most cases it leads to sudden death. it has been confirmed that 15% of patients with chronic alcoholism suffer from alcoholic cmp and 18% of them die accidentally [1,4]. research

1121105677 publisher: oscar publishing services servi this type of cmp develops from the specific effects of alcohol on the heart. the main reason is chronic alcohol consumption, drinking 100 ml every day for 10-20 years. histological examination reveals that the muscle fibers are thickened and there are many connective tissue fibers between the muscles, the typical characteristic of this kmp is that the interstitial tissue is wide, the muscle fibers are stiffened, and there are large thrombi attached to the inner wall of the left ventricle [2,6]. the purpose of the research: to clarify the specific macroand microscopic changes of the heart in alcoholic cardiomyopathy; methods we reviewed 5,642 reports from the rpam autopsy department during 2011-2020, and a total of 64 cmps were identified during this period, accounting for 1.13% of all autopsies and 4.7% of cardiovascular diseases. 11 of the 64 identified cases were alcoholic cardiomyopathy. after macroscopic examination of the heart, 1.5x1.5x0.5 cm pieces taken from the walls of both ventricles and both compartments were frozen in a 10% solution of formalin in phosphate buffer for 48 hours, then washed in running water for 3-4 hours and placed in a series of alcohol batteries of increasing concentration (80˚ , 90˚, 96˚, 96˚, 100˚) and dehydrated in chloroform, paraffin with added wax was poured, and bricks were prepared. histological sections 5-6 μm thick were taken from paraffin blocks and stained with hematoxylin-eosin and van gieson stain to identify connective tissue fibers. histological preparations were studied in 10, 20, 40 lenses of a light microscope, and pictures were taken from the necessary areas. results due to the chronic intoxication of the body under the influence of alcoholic kmp ethanol, in most cases, due to the lack of proteins and thiamine in the heart tissue, all parts of the organ become enlarged almost to the same extent, their cavities expand, often the right ventricle becomes enlarged and dilated. in our material, 14 cases of alcoholic kmp were detected, all of which had a dramatically enlarged heart, with an average weight of 582.7 g. it was observed that the heart was filled with fat in some of them. it was observed that the heart was macroscopically enlarged, reddish in color, softened in consistency, and spread out like dough when placed on the table. from the cavities of the heart, it was often found that the right ventricle was suddenly enlarged, and its wall was dilated. microscopic examination of this condition revealed that this type of kmp is a characteristic change, that is, the myocardial interstitial tissue is strongly swollen, as a result of which each of the muscle fibers is shriveled and located separately (fig. 1). separated muscle fibers are crooked, some of them are cracked, the transverse extension lines are not well visible, they are sparse. cardiomyocyte nuclei are few and those that are present are hypertrophied and enlarged. it is determined that the connective fibers in the interstitial tissue are shortened and turned into a sparse network, https://doi.org/10.37547/ajbspi/volume03issue03-01

volume 04 issue 06 pages: 79-86 oclc – 1121105677 publisher: oscar publishing services servi and the cells are suspended. it is observed that the swelling of the interstitium is even stronger in the areas where the blood vessels are located, as a result of which the structural units of the connective tissue are disintegrated, blood is poured around the vessels in a diapedesis manner. it is determined that the wall of the arterial blood vessels is narrowed due to sclerosis, the tissue structures in the wall are dense with each other and form a whole layer. it is observed that the blood vessels of the vein are sharply expanded, the wall is thinned, the cavity is filled with blood, blood is poured around it in a diapedesis method (fig. 2). it is determined that the murash fibers located in this area are shriveled and fragmented, some of them undergo myolysis, and others undergo vacuolization. in most cases of alcoholic kmp, it is determined that the interstitial swelling spread in the myocardial tissue simultaneously spreads to the interstitial tissue and the cytoplasm of parenchymatous cells, that is, cardiomyocytes. this condition is called myocardosis, the reason for which is a metabolic disorder in alcoholism, that is, due to a violation of the protein synthesizing function of the liver, there is less protein in the myocardium, instead of it, thiamine substance increases, and the swelling process develops in both interstitial tissue and cardiomyocytes. microscopically, small vacuoles appeared in the sarcoplasm of some cardiomyocytes, while in others, a tumor center appeared under the outer cytolemma (fig. 3), around myofibrils. in this case, it is determined that the nucleus and myofibrils of cardiomyocytes are pushed to the edge of the cell. figure 1. alcoholic kmp. myocardial interstitial tissue is severely swollen and muscle fibers are separated from each other. paint: g-e. floor: 10x40.

the wall of blood vessels and around it, as well as the growth of connective tissue, were noted. in this photomicrograph, it is clearly seen that due to the development of a very strong swelling in the interstitial tissue of the myocardium, muscle fibers are separated and torn. if we pay attention to the wall of the artery, it is determined that the connective tissue has a different thickness due to growth and destruction. in one part of the arterial wall, it is determined that the tissue structures have hardened, fatty substances have accumulated between them, and even spread to the endothelium layer, bulging it (fig. 4). another reason for myocardium swelling and dilatation in alcoholic kmp is that the process of extracellular and intracellular swelling in some areas of the myocardium eventually destroys the sarcoplasm and myofibrils of cardiomyocytes and leads to myolysis (fig. 5). in this area, accumulation of lymphohistiocytic cells in the interstitial tissue and around blood vessels, their activation and hypertrophy and hyperchromasia are determined. as another pathological change in the composition of cardiomyocyte cells, foci of lipofuscinosis and calcinosis are observed. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 84 american

fact it has been confirmed that fat cells grow into the interstitium of the myocardium from the adipose tissue under the epicardium. in our material, it was found that

group (gme+pt) displayed the most pronounced reduction in oxidative stress markers and the highest levels of antioxidant enzyme activities compared to all other groups. these findings suggest a synergistic effect between garciniamangostana l. rind extract supplementation and physical training in mitigating oxidative stress during maximal physical activity in wistar rats. discussion the observed reduction in oxidative stress markers and enhancement of antioxidant enzyme activities in rats supplemented with garciniamangostana l. rind extract highlight the potential antioxidative properties of the extract. garciniamangostana l. rind extract is rich in bioactive compounds such as xanthones and flavonoids, which possess potent antioxidant properties. these compounds may scavenge reactive oxygen species (ros) generated during physical activity, thereby reducing oxidative damage to cellular components. physical training is known to induce adaptive responses in antioxidant defense mechanisms, resulting in increased enzymatic activities of antioxidant enzymes such as superoxide dismutase (sod), catalase (cat), and glutathione peroxidase (gpx). the observed enhancement of antioxidant enzyme activities in rats subjected to physical training underscores the importance of regular exercise in bolstering endogenous antioxidant defenses and mitigating oxidative stress. the synergistic effects observed in the combined intervention group (gme+pt) suggest that garciniamangostana l. rind extract supplementation and physical training may act through complementary pathways to mitigate oxidative stress. the extract may augment the antioxidant capacity of the rats, while physical training enhances the efficiency of antioxidant enzyme systems. together, these interventions confer greater protection against oxidative damage induced by maximal physical activity. conclusion in conclusion, the findings of this study support the efficacy of garciniamangostana l. rind extract supplementation and physical training in mitigating oxidative stress in wistar rats during maximal physical activity. the antioxidative properties of garciniamangostana l. rind extract, coupled with the adaptive responses induced by physical training, offer promising strategies for enhancing antioxidant defense mechanisms and reducing oxidative damage associated with intense exercise. these findings have implications for the development of novel interventions aimed at promoting health and fitness while minimizing the risk of oxidative stressrelated complications. further research is warranted to elucidate the underlying mechanisms of action and assess the translational potential of these interventions in human populations. by harnessing the

determined. insects are usually mobile at temperatures between 10-40c, when the temperature drops, insects stop moving after feeding and die. an increase in temperature above the norm also has a negative effect on insects. temperature also affects the maturation of the sexual product of insects. after hatching, the swedish oat fly lays eggs after 10 days at 22c, and 50 days at 7c-14, 14c-36 and 4c. aquatic insects. many different insects live in clean waters. some of them spend their whole lives on the ground, others only in the larval stage, and as they develop, they move to the air environment. water insects are protected from moisture: their bodies are covered with a thick pile layer, a waterproof shell or a layer of fat. but this does not prevent some from flying beautifully. water insects need to store oxygen to live underwater. breathing patterns vary by species. most aquatic larvae breathe through their gills, which are small "pouches" under the skin. they absorb oxygen from the water through the surface of the body. thus, this method of breathing is characteristic of dragonflies and mayfly larvae. mosquito larvae hang on the surface of the water and take oxygen from the air with the help of special respiratory tubes. and stores them under the elytra or in the villi covering the body. one of the brightest representatives of aquatic insects. the dragonfly has a wingspan of 3 cm and can be found along rivers and near fresh water. dragonfly larvae, unlike adults, live in water and feed on small aquatic insects. she is a monster like her older sister. aquatic insects they are a group of organisms belonging to the class phyllum arthropoda and class insecta that exhibit morphological adaptations for living in an aquatic environment. these adaptations can be in the aquatic environment only in the first stages of life or in its entire cycle. insects are the most diverse group of animals in terms of the number of species, morphological, ethological (behavioral) and physiological diversity. more than 1 million described species are able to eat a wide variety of foods and feed on a wide variety of organisms. evolutionarily, insects are thought to have moved from terrestrial to aquatic environments. these organisms (about 30,000 species) were found in freshwater basins, rivers and lakes in potentially exploitable environments and almost without competition, which was not the case in the marine environment. in this latter environment, they had to compete with groups such as crustaceans. therefore, they did not thrive in the sea. now the adaptations that allow insects to be successful in aquatic environments are: swimming for changed legs ( for example, oars to hear forms ). on the legs swimming mushrooms ( to hair similar structures ). to swim facilitating belly flattened. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue

development possible about never how evidence no. this makes it safe and environmentally friendly to use nematodes in insect pest control. the united states environmental protection agency (epa) has ruled that nematodes are exempt from registration because they occur naturally and do not require human genetic modification. beneficial nematodes are soil-dwelling insects that are present at any time of the year. can be applied when soil temperatures are above 52° c during the day. target pests include: cucumber beetles, grubs, weevils, strawberry rootworms, may beetles, masked beetles, cranberry rootworms, flea beetles, weevils, and japanese beetles. weevils, strawberry root and black vine borers, chafer, squash bugs, leaf beetles, cucumber beetles,, white grubs, algal midges, black flies, potato tubeworms, mealworms, scab i beetle, corn root weevil, fire ant, sting bugs, pine beetle, grubs, gypsy moth, corn rootworm, billbug, colorado beets, ants and termites (applied directly to mounds and nest sites) and many other deep soil insects. they are very effective when the pest is widespread in the soil, because they break through the insect's skin and kill adult fleas in the yard, pet areas, and soil. it is most effective against flea larvae and caterpillars in lawns, garden soil, and under trees where the larvae pupate. they wait to ambush pests that live on the surface. steinernema is the most studied species for insect control. the insect has a "tooth" to penetrate the body wall and pores. many species of fly larvae are important soil pollinators. they are restricted to moist conditions rich in organic matter. some larvae are carnivorous and have adaptations to reduce moisture loss that occurs in drier conditions (teskey, 1990). mosquito larvae greatly affect the rate of carcass decomposition. various types of worms in combination with certain types of beetles significantly accelerate the rate of decomposition. when payne (1965) used a window screen to exclude insects from decaying carcasses of piglets, the carcasses were mummified and decomposed more slowly than those exposed to insect attack. fly larvae court it is also important in entomology on the ground their identification a person of corpses scientist the time in determining help will give. arthropods can be divided into groups of shredders, carnivores, herbivores and fungi feeders according to their functions in the soil. most soil-dwelling arthropods feed on fungi, worms, or other arthropods. fewer root feeders and shredders of dead plants. as arthropods feed, they aerate and mix the soil, regulate populations of other soil organisms, and break down organic matter. many large arthropods commonly found on the soil surface are shredders. shredders chew up dead plant matter while eating bacteria and fungi on the surface of the plant matter. most a lot shredders are millipedes and sowbugs, as well as termites, some ticks and roaches. village economy in the soil, grinders

common mosquitoes are bloodsuckers, and their larvae, which develop in water, feed on microorganisms and suspended organic debris. larvae breathe atmospheric air with a breathing tube. the malaria mosquito can be distinguished from the common mosquito by its landing position: the common mosquito holds its body parallel to the surface on which it sits, while the malaria mosquito holds its body at an angle. their larvae are also different. larvae of malaria flies rise to the surface, holding the body parallel to the surface film of water, and normal mosquito larvae at an angle to it. to reduce the number of malaria mosquitoes, swamps are drained, and fish are raised that feed on mosquito larvae and pupae. they play an important role in reducing the number of mosquitoes. natural

clinical laboratory tests; determination of the level of thyroid hormones (tsh, t3, t4); examination by an endocrinologist; examination by an ent doc-tor in case of phonation disturbance. morphological studies of the parathyroid gland included fine-needle aspiration biopsy, intraopera-tive express biopsy, and routine histological examination of removed thyroid tissue. at the same time, in the comparison group (230 patients), tpab and a final histological examination of the removed thyroid specimen were performed to determine the likelihood of malignancy of the node. in the main group of patients (138 patients), in addition to determining the factor of possible thyroid cancer, the nature of be-nign changes in nodular and perinodular tissue was differentiated. the algorithm

effectiveness of surgical intervention for ptg is the frequency of dis-ease relapses. when studying the nature of the relapse, the localization of the initially operated and re-identified node, the timing of the relapse, the features of previously used methods of surgical interven-tion, the number, size and morphological forms of primary ptc were compared. of 268 patients examined long-term, recurrence of ptg was observed in 33 (12.3%) patients, while in the group of patients operated on in 2010-2014, this figure reached 26.4% (table 4). subse-quently, the frequency of disease relapses was reduced in the 2nd subgroup of the comparison group to 8.0%, and in the main group to 3.8% (χ2 criterion = 4.692; p = 0.031). we studied and analyzed the long-term results of surgical treatment of

severity and duration of thyroid hormone deficiency, as well as on the age of the patient and the presence of concomitant diseas-es. the faster hypothyroidism developed after surgical removal of the thyroid gland, the faster it was accompanied by obvious clinical manifestations. on the other hand, even with the same severity and dura-tion https://doi.org/10.37547/ajbspi/volume03issue03-01

very individual. that is, on the one hand, completely obvious hypothyroidism could not have any clinical manifestations and was discovered by chance, on the other hand, some patients with subclinical hypothyroidism could present a lot of complaints charac-teristic of complicated severe hypothyroidism. thus, the developed algorithm for choosing tactics for surgical treatment of ptg, taking into ac-count the volume of thyroid removal according to the conclusion of tpab or express bopsy, made it possible to improve the quality of care provided by reducing the frequency of immediate postoperative complications from 14.8% (40 patients in the comparison group) to 2 .9% (4 patients in the main group) (χ2 criterion = 4.954; df=1; p=0.027) and unsatisfactory results in the long-term postoperative period from 32.1% (52 patients in the comparison group) to 11.3% (in 12 patients in the main group) (χ2 crite-rion = 4.692; df=1; p=0.031). conclusions • factor analysis of the results of treatment of patients with pto showed that the cause of relapse in 26.4% was the performance of organpreserving surgical interventions for nodular cystic colloid goiter with foci of adenomatosis and a combination of various types of adenomas with multinodular col-loid goiter. the cause of the development of postoperative hypothyroidism in 24% of cases was exceed-ing the indications for performing operations associated with total removal of the thyroid gland. • in the morphological diagnosis of ptg, the information content of tpab was 91.8%, express biopsy was 94.4%, the combination of these methods increased the information content to 98.1%. the introduction into clinical practice of morphological diagnosis of changes in the nodular and perinodular tissue of the thyroid gland in patients with ptg has made it possible to select the optimal volume of sur-gical intervention. • the developed algorithm for selecting the volume of surgical intervention for ptg, taking into account the data from the conclusion of tpab and/or express bopsy, made it possible to improve treat-ment results by reducing the frequency of immediate postoperative complications from 14.8% to 2.9% and

against it are important tasks in medicine, and in oral medicine in particular [1,2]. according to the international cancer research foundation (wcrfi) cancer morbidity and mortality is directly related to the level of economic development and, despite the fairly high standard of living in the world, continues to grow constantly [3]. according to who (1993), cancer damage to organs and tissues of the mouth is in 4th place, after cancer of the lung, stomach and colorectal area [4]. according to literature sources, about 6,000 patients with oral cancer are diagnosed every year in russia. about 40% of all head and neck cancer incidence is due to oral cancer. in terms of frequency of occurrence, after laryngeal cancer, oral cancer ranks 2nd. in the structure of oncological morbidity in russia, oral cancer accounts for 1.5% of all oncological diseases of various organs and systems [3,1]. over the past 15 years, the incidence of cancer of the oral cavity, pharynx, and larynx has increased by 15-17%, and almost 90% of patients are working people (30-60 years old). despite the localization of tumors being quite convenient for examination, 60-70% of patients, according to v.a. lazareva, seek treatment for tumor processes at stages iii-iv [5]. tumors of the maxillofacial region are diverse both in morphological structure and in the variability of clinical manifestations, and therefore early diagnosis and treatment of these diseases are still difficult [6]. precancerous conditions in most cases precede cancer. the concept of precancer refers to chronic inflammatory processes, benign neoplasms, disturbances in the keratinization process , and atypical keratinization [6]. according to modern literature sources, precancers account for from 15.2 to 84.9% of all diseases of the oral cavity [7]. precancer does not cause complaints in patients for a long time, and therefore is often not diagnosed in the early stages. great difficulties arise in differentiating precancer from the onset of malignancy due to the variety of precancerous diseases in clinical course, morphology, and in the early stages of malignancy due to the lack of clear clinical signs [6]. it is well known that there is a high probability of precancerous diseases becoming malignant, so their timely detection and treatment is very important, which increases the chance of preventing the development of cancer and increasing patient survival [4]. recognizing early forms of cancer prevents the progression of the malignant process, and treating a tumor in the early stages helps reduce mortality, which solves an important medicalbiological and social problem in oncology [5]. the standard diagnostic algorithm includes a survey and examination. the most commonly used are visual and visual-instrumental methods, and also use cytological, histological methods, vital staining techniques, stomatoscopy, biomicroscopy. there are also histochemical methods, dna cytometry , luminescent and radioisotope studies, and electron microscopy. the development of spectroscopy techniques is promising [4]. the histological method is the main

services servi method of differential diagnosis for a dentist [6]. in this study of the material, two classifications are used: the clinical classification of a.l. mashkileison (1970) and who classification (2005). to assess the degrees of dysplasia, according to the who classification, doctors use squamous intraepithelial neoplasia ( squamous intraepithelial neoplasia – sin) from 1 to 3 – depending on the severity of dysplasia [8]. this classification quite clearly describes the stages of malignancy , however, it is not always possible to practically assess the severity of dysplasia, and therefore a variety of additional techniques are used [9]. currently, immunohistochemical diagnostics make it possible to clearly differentiate various tumors to identify the expression of the proliferation marker ki-67, the marker of apoptotic activity p53 and cell adhesion proteins. it is this study that helps determine the degree of dysplasia of the epithelium of the oral cavity, since the availability of clinical and histological data does not always allow an accurate assessment of the degree of malignancy. in all phases of the mitotic cycle, except for go, the ki-67 protein is observed in the cell a universal marker of proliferating cells, which has important prognostic significance for varying degrees of dysplasia. for histological examination and immunohistochemistry , sections of the mucous membrane 5 μm thick are mounted on glasses. the ki67 proliferation index (ki67 pi) was determined by the ratio of the number of immunoreactive cell nuclei to the total number of cell nuclei in % [9,10]. in an immunohistochemical study of the mucous membranes in all studied preparations, a pronounced expression of ki-67 was observed in the nuclei of proliferating cells. in the normal epithelium of the oral mucosa, all immunopositive cells were localized in the basal layer, while in leukoplakia (sin1, sin2 and sin3), an immunohistochemical reaction with antibodies to ki-67 was detected mainly in the nuclei of cells of the basal and parabasal layers. in the unchanged epithelium of the oral mucosa and in leukoplakia, in the superficial layers the number of these cells was less than 1%. in squamous cell carcinoma, the tissue architecture was completely disrupted and the division of the epithelium into layers was practically absent. positively stained cells were distributed evenly from the basement membrane to the epithelial surface. to assess proliferative activity in normal epithelium of the oral mucosa, leukoplakia and squamous cell carcinoma, cells positively stained for ki-67 were counted in all layers of the epithelium (pi 0) and separately. a number of studies have shown the highest proliferation index in squamous cell carcinoma, and also reveal a relationship between an increase in the epithelial proliferation index by ki-67 and an increase in the degree of epithelial dysplasia. according to kovyazin v.a. et al . it was found that the proliferative activity of cells in the basal layer of the mucous membrane of the mucous membranes decreases as the degree of neoplasia increases, while in the parabasal layer this indicator increases

publishing services servi immunohistochemistry of intact stratified squamous epithelium, pronounced expression of claudin-1 is noted in the cells of the basal, parabasal and spinous layers. thus, in hyperplasia, a high degree of cell proliferation is manifested by a decrease in the level of claudin-1 expression, and severe neoplasia is manifested by the complete absence of this protein on the cell surface [10]. according to modern studies, the presence of the p53 protein is noted in the nuclei of cells of all layers of the epithelium of the oral cavity, in normal epithelium and in all types of leukoplakia. with the increase of dysplasia in all layers of the epithelium, the number of cells with this protein increases, their maximum number in squamous cell carcinoma [6]. immunohistochemistry is also used to identify hpv16 antigens and proteins associated with hpv-p16ink4a in epithelial cells in various types of leukoplakia and cancer. thus, according to a number of authors, increased expression of p16ink4a is an indirect indicator of hpv and thereby reflects a violation of the mechanisms responsible for cell proliferation. this indicator also confirms the presence of an infection with a high risk of developing neoplasia [11]. optical coherence tomography (oct) is a diagnostic method based on imaging the microstructure of tissues using near-infrared light [11,12]. according to modern literary sources, this research method is based on the difference in the optical properties of tissues depending on their structure. with oct, it becomes possible to obtain images of subsurface structures at a depth of up to 2 mm. this method is used in clinical practice for the differential diagnosis of clinically similar diseases, precancers and cancer, fixing the boundaries of a malignant neoplasm, determining the optimal location for a biopsy, and also dynamic monitoring of the state of the oral cavity during treatment [12]. according to rabinovich o.f. et al ., to describe oct images of the sop, concepts such as layering, structure, boundary characteristics, surface character, optical inhomogeneity, image depth, brightness, contrast are used. the main sign of malignancy is loss of structure, which is confirmed by a homogeneous homogeneous image with a shallow signal depth or its absence [11]. currently, cancer screening methods are becoming increasingly popular . according to modern literature sources, screening is a system of primary selection of individuals with a latent disease through simple, safe and inexpensive methods for the purpose of further in-depth examination [6,13]. material and methods of research there were 32 patients (15 men and 17 women) aged 35 to 60 years with oral precancerous diseases examined at the department of therapeutic dentistry of tashkent state dental institute. the diagnosis of leukoplakia was made based on clinical examination, optical coherence tomography, histological and ihc studies. histological examination is considered the “gold standard” for diagnosing diseases of the oral https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

the advantage of a biopsy is the ability to study the pathological process at the cellular level, but the main disadvantage is its invasiveness . the success of histological examination and the objectivity of the diagnosis largely depend on the correct location for taking the biopsy [1, 9]. according to the who classification (2005), leukoplakia without atypia , leukoplakia sin1, sin2 and sin3 ( squamous intraepithelial neoplasia ). ihc research makes it possible to characterize the pathological process in various layers of the oral mucosa epithelium at the molecular level [2, 3]. the collection of biopsy material for research was carried out with the written consent of the patients. the ihc study was carried out in accordance with the standard protocol. tissues were fixed in 10% neutral formaldehyde ( ph 7.4) and, after soaking in alcohol, embedded in paraffin with a melting point of 54 °c. for histological and ihc studies, serial sections 5 µm thick were mounted on polyl-lysinecoated glass . using mouse monoclonal antibodies, tissue antigens to ki-67 were detected (clone mm 1, diagnostic biosystems 1:200), to keratin-8 (clone ts1, thermo scientific 1:100) and using purified rabbit antiserum antibodies to claudin-1 ( thermo scientific 1:200). immune complexes were determined using a biotin-free detection system based on horseradish peroxidase ( biogenex , usa); sections were counterstained with mayer's hematoxylin [3]. results and discussion of the 32 patients we examined, 20 were diagnosed with flat leukoplakia and 12 with verrucous form. histological mucosal lesions in the clinical diagnosis of leukoplakia can range from hyperplasia to invasive cancer. the superficial keratin layer can be located above benign, mature stratified epithelium of the squamous or pseudoepitheliomatous type or on mucosa with mild, moderate or severe dysplasia (sin 1, sin 2 or sin 3). with hyperplasia, thickening of the epithelium is noted due to an increase in one of its components basal, spinous ( acanthosis ) or superficial ( hyper, parakeratosis ) cell layers, without cellular atypia . slight increase in cell density and cellular atypia possible due to inflammation. histological examination of foci of verrucous leukoplakia against the background of thickening of the surface keratin layer reveals an expansion of the layer of spinous cells with dyskeratic changes. in the subepithelial connective tissue base, individual lymphomacrophage infiltrates are found. an ihc study in patients diagnosed with flat leukoplakia did not reveal neoplastic transformation of epithelial cells; the main changes in the epithelium were characterized by hyperplasia with cell proliferation (nuclear localization of the ki-67 protein) in the basal and parabasal cell layers, the absence of ectopic expression of keratin-8 in epithelial cells and well-developed intercellular contacts (claudin-1). in patients with verrucous form of leukoplakia, according to ihc diagnostics, the following results were obtained: in 9 sin 1, in 1 sin 2 https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

of epithelial cells of the lower third of the mucous membrane , in the same zone, ectopic expression of keratin-8 and the absence of membrane staining of cells for claudin-1 were detected. in patients with sin 2, nuclear expression of ki-67 protein, keratin-8 and decreased expression of claudin1 in the lower 2/3 of the mucosa were determined. in 2 patients with sin 3, cell proliferative activity of the ki67 protein and ectopic expression of keratin-8 were observed in all layers of the mucosal epithelium in the absence of expression of the intercellular contact protein claudin-1. thus, clinical examination and ihc examination biopsy material for proteins ki-67, keratin8 and claudin-1 are the most informative methods for diagnosing various forms of leukoplakia, in which malignancy is

introduction an increase in surgical activity associated with the improvement of surgical techniques and anesthesia methods has led to an increase in the number of patients with postoperative ventral hernias (povh) by 9-10 times over the past 25 years [7]. every year, about 20 million hernioplasties are performed in the world, of which approximately 700 thousand are performed in the usa, about 1 million in europe, and up to 2 thousand in uzbekistan [4, 7, 10]. in this regard, the problem of surgical treatment of povh remains an urgent task in abdominal surgery. these hernias take second place after inguinal hernias, and account for 20-22% of the total number of abdominal wall hernias. in approximately 50% of cases, povh develops within the first two years after surgery, and 75% after three years [2, 5, 6]. the problem of effective treatment of povh has not been fully resolved. despite the large number (more than 200) of proposed methods for their surgical treatment, the rate of disease relapse remains high, amounting to 15-50%, and repeated operations are accompanied by its increase to 20-65% [1, 3, 8]. the inconsistency of assessments of the proposed methods of surgical treatment of povh, the variety of traditional methods of hernia repair used and the emergence of new methods using various mesh implants make it difficult to choose the most rational method of plastic closure of the hernia defect. in modern conditions, various methods of tension-free hernioplasty using a variety of synthetic mesh implants are considered the operation of choice for poig. tension methods of hernioplasty using local tissues have practically ceased to be used due to the high frequency of relapses and remain in the arsenal of surgeons only for small poigs [1, 9]. since the late 1990s, the development of laparoscopic technology and the introduction of new synthetic materials have pushed surgeons to develop and introduce into practice laparoscopic methods for the treatment of povh. however, to this day, the following issues of laparoscopic hernioplasty remain unresolved: the rational choice of a mesh implant according to the quality/price criterion, the method of its placement and method of fixation, the problem of delimiting the mesh implant from the abdominal organs, determining the indications and contraindications for this type of plastic surgery [2] . the purpose of the study improving the results of laparoscopic hernioplasty for postoperative ventral hernias. method the study is based on a clinical examination of 105 patients with postoperative ventral hernias

operation, patients were divided into two groups:the first group (main group) consisted of 50 patients operated on laparoscopically, the second group, the comparison group included 55 patients who underwent open (traditional) prosthetic hernioplasty. among the patients there were 58 men, 47 women. the location and size of the pih were determined using the classification proposed by the european society of herniology (modified and based on the classification of j. chevrel and a. rath) and adopted by international consensus (belgium, october 2-4, 2008) [10]. according to this classification, the following types of povg are distinguished: i) by localization: m medial hernia (borders of the midline of the region: cranially the xiphoid process, caudally the pubic bone, from the side the lateral edges of the rectus abdominis muscle): m1 subxiphoid hernia (from the xiphoid process to 3 cm caudally); m2 epigastric hernia (from 3 cm below the xiphoid process to 3 cm above the umbilical ring); m3 umbilical hernia (from 3 cm above to 3 cm below the umbilical ring); m4 infraumbilical hernia (from 3 cm below the umbilical ring to 3 cm above the pubis); m5 suprapubic hernia (from the pubic bone to 3 cm cranially). l lateral hernia (limits of the lateral surface area: cranially the edges of the costal arches; caudally the inguinal areas, medially the lateral edges of the rectus abdominis muscle, laterally the lumbar region): l1 hypochondrium (from the anterior edge and horizontal line 3 cm above the umbilical ring); l2 flank (on the side of the rectus muscle 3 cm above and below the umbilical ring): l3 iliac region (between the horizontal line 3 cm below the umbilical ring and the groin area); l4 lumbar region (latero-dorsal part from the anterior axillary line). various defects in the anterior abdominal wall caused by one incision are considered as one hernia, two or more different surgical incisions are considered as two or more hernias. ii). according to the size of the hernial orifice: w1 <4 cm; w2 ≥ 4-10 cm; w3 ≥ 10 cm. the width of the hernia defect is defined as the greatest horizontal distance in cm between the lateral edges hernia defect on both sides. in the case of multiple defects, the width of the hernia is measured between the most transversely located edges of the most laterally located defects on the same side. the length of the hernia defect is defined as the greatest vertical distance in cm between the most cranial and most caudal edges of the hernia defect. in the case of multiple hernia defects from one incision, the length is measured between the most cephalad defect and the most caudal defect. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

using a karl shorz video complex. the main working instruments for laparoscopic prosthetic hernioplasty were: ultrasonic scalpel “harmonic” (ethicon) and 5 mm endoscopic herniostapler “protack™” (covidien). surgical intervention was performed according to standard techniques. stage i – insertion of the first trocar in conditions of povh, as far as possible from the hernia, in an area free from adhesions. typically, entry into the free abdominal cavity was carried out in the left hypochondrium or in the left iliac region using a special optical trocar “visiport™” (covidien) or under visual control using the hasson technique. stage ii of the operation after the introduction of the first trocar with optics and revision of the abdominal cavity, 2 or 3 working trocars were introduced. the sites for trocar insertion in patients with poig are not standardized and were chosen where it was more convenient and safe. at the same time, we tried to observe the principle of

surgery. the 36 questionnaire items were grouped into eight groups, characterizing: physical functioning, i.e. ability to withstand physical activity; role physical functioning, which reflects the impact of physical condition on daily activities; pain intensity and impact of pain on daily activities; general health; general activity, energy; social functioning; role-emotional functioning, which characterizes the influence of the emotional state on everyday activities; mental health. the first 4 groups of questions of this scale characterized the patients’ assessment of their physical health, and the 5-8 groups of questions reflect the main parameters of mental health. results and discussion the general results of surgical treatment of patients with povh are presented in table 2. table 2.

services servi the average duration of laparoscopic hernioplasty was85.4 ± 8.4min., which turned out to be less than with open hernioplasty -102.4 ± 9.7min. (p ˂ 0.05). we associate the reduction in operation time with laparoscopic access with the absence of the following stages, standard for open hernioplasty: 1) incision of the skin and subcutaneous tissue, 2) wide detachment of subcutaneous tissue from the aponeurosis along the entire perimeter of the hernial orifice, 3) thorough hemostasis along the course of the hernial sac and hernial orifice, 4) manual fixation of the mesh using interrupted or continuous sutures, 5) layer-by-layer suturing of the skin wound. postoperative local wound complications were detected in 6 patients (12.0%) of the main group, while in the comparison group they were recorded in 24 (43.6%), which is 3.6 times more than in the main group. all wound complications were eliminated by conservative measures and puncture methods under ultrasound guidance. the results obtained confirm the minimal trauma of the endovideosurgical approach to performing hernioplasty and demonstrate a reduction in the incidence of postoperative local complications by 31.6% compared to similar results in patients operated on by laparotomy. in our opinion, this is directly related to minimizing the size of the surgical approach and reducing the area of the wound surface, the absence of lymphorrhea and tissue exudation, the absence of a postoperative cavity between the skin and the aponeurosis, as well as the location (intraperitoneal) of the mesh implant during laparoscopic hernioplasty. conclusions • the supraponeurotic placement of the mesh implant using the “onlay” method is associated with a large number of wound complications (grays, hematomas, infiltrates, purulent complications) and a high risk of relapse of poig. • with the “inlay” technology, the risk of developing wound complications and the likelihood of relapse of poig is significantly lower, but this method is more technically complex and is not always possible. • the use of the laparoscopic “ipom” technique can significantly reduce the number of early postoperative and general complications (by 3.6 times), the duration of hospitalization (from10.2 ± 1.8days before6.2 ± 0.8days), periods of temporary disability (from40.9 ± 5.6days before15.1 ± 1.8days), and also reduce the number of relapses (from 10.9% to 2.0%). • in modern conditions, the method of laparoscopic hernioplasty can be recommended as the operation of choice in patients with pvh. references 1. yu.h. abdurakhmanov, v.k. popovich, s.r. dobrovolsky. quality of life of patients with postoperative ventral hernia in the long-term period // surgery.

article describes recommendations for correcting water-electrolyte balance during physical training of football players, as well as daily energy expenditure and caloric content of daily menu products. keywords preparation of football players, daily energy expenditure, water-electrolyte balance, correction. introduction the main pattern of nutrition should be the correspondence of daily energy consumption and daily calorie content of food. if caloric intake exceeds energy expenditure, this leads to fat deposition and digestive disorders. insufficient calorie content with high energy expenditure leads to gradual depletion of the body, so to speak, to “self-food”. athletes' daily energy expenditure is 3000-6000 kcal, and under very intense training and competition conditions, energy expenditure reaches 7000-8000 kcal. energy consumption depends not only on the amount of work performed, but also on the emotional factor, which was clearly revealed during competitions.

volume 04 issue 06 pages: 18-24 oclc – 1121105677 publisher: oscar publishing services servi an athlete’s nutrition must be rational, that is, sufficient in quantity and complete in quality. rationality is based on balance the optimal ratio of basic nutrients: carbohydrates, fats, proteins, vitamins, mineral salts and their components (essential and nonessential amino acids, lipids and unsaturated fatty acids, microelements, etc.). adequate nutrition is achieved by the correct ratio of nutrients in the diet. there are six classes of nutrients: water, carbohydrates, fats, proteins, vitamins, minerals. water is life. the human body consists of 60-65% water. metabolism occurs in an aquatic environment. water is contained in tissue cells, blood, and digestive juices. the amount of water in an athlete’s diet should be 22.5 liters, taking into account soups, milk, coffee, tea, as well as water contained in various dishes, fruits and vegetables. on days of intense training and competition, the need for water increases sharply. during training and competitions, it is better to use alkaline mineral waters (borjomi, narzan and others), to which it is useful to add slices of lemon. football players often drink tea with lemon. you should drink water, juices or tea in small portions, keeping it in your mouth for a long time. when increasing exercise, water serves two important functions: regulates body temperature, in particular, provides cooling during exercise; delivers nutrients to cells and removes “waste” from them. here are some recommendations for football players regarding water consumption: drink 6-8 glasses of water per day; drink 2 glasses of water 15 minutes before training or playing; after training or a game, drink 2 glasses of water more than you need to quench your thirst; drink 1 glass of water every 15-30 minutes during training or play; drink cooled liquids to speed up the transition of substances from the stomach to the blood, as well as to cool the body more quickly; drink 1 glass of water after drinking caffeinated drinks (caffeine is known to be a diuretic and therefore causes dehydration). getting enough water into your body is an ongoing, vital process that experts call hydration. water is a universal solvent. most body chemicals are soluble in water. due to its low viscosity, water easily moves through blood and lymphatic vessels, through intercellular spaces and transports substances soluble in it. thus, water performs a transport function. water is involved in maintaining a constant body temperature, i.e. performs a thermoregulatory function. water forms a hydration shell for highmolecular compounds (proteins, polysaccharides) and thereby contributes to their stability. water is an active participant in metabolism. for example, the https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 20 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 18-24 oclc – 1121105677 publisher: oscar publishing services servi breakdown of nutrients during digestion occurs exclusively through hydrolysis, i.e. with the participation of water. water is also the end product of a number of chemical processes occurring in the body. a large amount of water (about 400 ml per day) is formed during tissue respiration. the human body contains about 3 kg of mineral (inorganic) substances, which is 4% of body weight. the mineral composition of the body is very diverse, and almost all known mineral elements can be found in it, however, their content is not the same. both short and long-term exercise require a good supply of water to the body, which must be regulated depending on the duration and intensity of the physical activity. to avoid dehydration, it is important to remember about thermoregulation, which is influenced by climatic conditions (temperature, wind), as well as factors such as level of training, clothing, etc. in addition, fatigue and stress are additional factors predisposing to dehydration. dehydration of the order of 1 2% of body weight (from 0.7 liters to 1.4 liters for a person weighing 70 kg) can lead to a decrease in muscle performance by 10%. dehydration of more than 4% can lead to severe fatigue, heaviness in the legs, shortness of breath, and also negatively affects the nervous system. over 6 8%, this is a real risk of death from dehydration. the most common cause of electrolyte deficiency is the neglect of many athletes to timely and adequately replenish fluid losses. in this regard, it is necessary to remember the following: ✓ during training or a game, a decrease in body weight due to sweating reaches 2 percent or more, which significantly reduces performance, and a loss of 7% leads to refusal to continue working; ✓ use various drinks, it is necessary to focus not on the feeling of thirst that arises, but on the intensity of exercise, while it is necessary to remember the following pattern: a rise in normal air temperature by 5c increases fluid consumption by 15%, an increase in body weight by 5 kg, more than 75 kg per 7% increases fluid intake [1,2]. ✓ replenishment of fluid losses must be carried out not with ordinary water, but with specially designed drinks that allow maintaining the proper level of performance due to the timely supply of easily digestible carbohydrates; ✓ consumption of carbohydrate drinks must be started before training and continued during and after it to maintain glycogenesis in the liver and muscles (for this purpose, glutamic acid preparations can be used). in the overwhelming majority of cases in elite sports, they resort to the use of pharmacological agents and biologically active additives that replenish the required volume energy supply to the body and ensuring the delivery of plastic substances: substance supplements or so-called sports nutrition, which is https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue

used as a supplement to a balanced diet, and does not replace it. currently, there are hundreds, if not thousands of sports nutrition companies. when choosing the product to use, the doctor should rely on the following points: 1) the drugs used must be certified in the country, which guarantees not only the safety of these products, but also their compliance with anti-doping legislation 2) the product line of the manufacturing company must cover the entire range of athletes’ needs for various training regimes 3) testing of drugs is permissible only with the consent of athletes and during training, starting with the minimum recommended doses of one of the drugs to determine the tolerability of its components 4) the use of sports nutrition should be systematic, and its volume and structure vary depending on the seasonal cycle. considering the extreme loads that determine the body’s constant need for plastic material and coenzymes involved in the most important biochemical reactions, in the practice of elite sports, substrate nutritional supplements are systematically used (proteins, carbohydrates, protein-carbohydrate mixtures-gainers, vitamin-mineral complexes, carnitine, creatine , fatty acids and essential amino acid complexes (bcaas) and vitamin-mineral complexes (vmc) [4,5]. the most common substrate additives are proteins and carbohydrates, including in the form of gainer mixtures (start-gainer, energy-optemeizer, max-amino), as well as creatine, carnitine, l-carnitine and vitamin-mineral complexes[6]. a distinctive feature of sports iuds is the multiple excess of the recommended daily doses of the main minerals and vitamins included in their composition, so they must be used during intensive and long-term training camps. during the season, it is sufficient to constantly take conventional iuds with a high content of b vitamins (vitrum, vitaminlight, vitamax, polizhen, max for men, etc.). taking these drugs leads to a significant increase in physical and mental endurance, improves body structure, and normalizes psychomotor reactions in unfavorable conditions of daily activity. in addition to sports ich, especially in the absence of timely biochemical monitoring, a preventive course of magnesium, the deficiency of which can lead to damage to muscle tissue, and zinc, which is fundamentally important for steroidogenesis, is necessary. one of the most common myths that exists in the football community is the opinion that creatine has a negative effect on the joint-muscular sensation of football players, which supposedly leads to physical defects. our data indicate only the beneficial effects of a course and targeted (before games) intake of moderate doses of creatine in combination with bcaas: with a course intake of up to 2 grams per day https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 22 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 18-24 oclc – 1121105677 publisher: oscar publishing services servi for 10-1 i days, with a single use before games up to 3-5 grams. the course intake is carried out at training camps with mandatory breaks between them, up to 5-7 days, in order to optimize the adaptive reactions of the athlete’s body. creatine monohydrate is phosphorylated in the liver, converted into creatine phosphate, which, entering the mitochondria of cells, participates in the reactions of atp reduction from adp (adenosine diphosphate), thereby providing the ability to release large amounts of energy without visible energy depletion. one of the most common substrate supplements, lcarnitine, is often used in targeted weight loss programs. in these programs, it is used along with thermogenics throughout the entire pre-workout weight loss period at a dose above 1500 mg. another area of application of l-carnitine is its use before games and intensive training during the season for a more efficient flow of energy supply processes, in such cases a dosage of up to 1500 mg is used 45-60 minutes before the game. dietary supplements (adaptogens, herbal anabolics, immunomodulators, antihypoxants, hepatoprogectors, etc.) the top of the pyramid of specialized sports nutrition are dietary supplements and substances used for targeted activation of various parts of metabolism, correction of psycho-emotional state and prevention of immunosuppression. the use of these drugs can be either a course or a onetime use. optimal, in our opinion, is the use of these drugs against the background of constant hematological screening (biochemical blood test, immunogram, hormonal spectrum). however, in practice, continuous monitoring is impossible due to logistical difficulties and paramedical factors (reluctance of the athlete and coaching staff, lack of proper organization). based on this, the use of these substances is often preventive and intuitive. the program we have developed focuses on maintaining a high level of endogenous testosterone in the athlete’s blood, as well as preventing the development of immunosuppression and activation of the body’s protective functions (hepatoprotectors, prebiotics, antihypoxants). to implement the first point of the program, we recommend the use of anabolic agents of plant origin and prohormones ( tribulus, ecdysterone, etc.) in courses of up to 10-14 days against the background of intense physical activity 2-4 times during the season. in practical medicine, immunomodulators are used only when changes in the immune status are identified. while recognizing the correctness of this approach in relation to ordinary people, we cannot agree with it in relation to high-level athletes, since almost always, against the background of prolonged intense physical activity, more or less pronounced changes in the immune status develop, which always precede the clinical manifestations of overtraining. . based on this, https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi we consider it advisable to take a course of preventive treatment with modern safe immunomodulators twice a year in courses of up to 10-14 days. one of the most important tasks is the activation of the body’s protective functions against the background of prolonged intense physical activity. traditionally, antihypoxants are used for this purpose, such as inhibitors of lipid peroxidation (hypoxen, actovegin, ubiquinone, serrata) and hepatoprotectors (essentiale, heptral, karsil, etc.) conclusion in conclusion, it should be noted that, as in other areas of elite sports, the development of pharmacological and nutritional correction programs in football is not possible without knowledge and understanding of the physiology of the training process, and without a clear understanding by the team’s coaching staff of the importance of these activities. references 1. актуальные аспекты спортивной медицины под редакцией мк рфс и.б.

publisher: oscar publishing services servi usa, more than 100,000 in russia, and about 10,000 in uzbekistan [5, 7, 13]. at the same time, the frequency and severity of bile duct injuries have noticeably increased and amount to 0.2 1.9% [2, 4, 7, 8, 9, 11, 14, 16]. authors dealing with this problem note that the introduction of laparoscopic cholecystectomy has led to a noticeable increase in the frequency and severity of bile duct injuries. taking the average frequency of injuries to the main bile ducts (mbd) as 0.5 1% in uzbekistan, from 50 to 100 people suffer from such a complication per year. treatment of bile duct injury is extremely difficult, requires expensive therapeutic and diagnostic procedures, and leads to serious disability in patients. mortality is 8-17%, complications during operations occur in up to 47% of cases, the development of posttraumatic strictures of the bile ducts up to 35-55% [1, 3, 6, 10, 12, 15, 17]. the timing of detection of ivs damage is important in the outcome of treatment. there are “fresh” injuries and post-traumatic scar strictures of the bile ducts and biliodigestive anastomoses. “fresh” injuries are divided into those diagnosed on the operating table and those detected in the early postoperative period. the results of studies, including in uzbekistan, show that only in 30% of cases iatrogenic damage to the bile ducts is recognized during surgery, up to 50% of damage is diagnosed in the postoperative period against the background of the development of peritonitis, rapidly increasing obstructive jaundice or bile leakage through the drainage. more than 15% of patients die from progressive peritonitis, increasing jaundice or other postoperative complications that are not recognized in a timely manner. for the healthcare of our republic, analysis of the frequency and causes of unsatisfactory results of surgical interventions on the biliary tract is extremely relevant. in addition, it is extremely important for practical surgeons to develop an algorithm of actions for “fresh” injuries of the bile ducts. purpose of the study: optimization of surgical treatment of “fresh” injuries of the main bile ducts. method an analysis of the results of surgical treatment of 103 patients with “fresh” ivs injuries in the period 2014 – 2023 was carried out. in our own observations, ivs injuries were noted in 38 (0.58%) patients in 6521 cholecystectomies; 65 patients were admitted from other hospitals with “fresh” ivs injuries. in 78 patients there was intersection (9), excision (38) and excision

reconstructive surgery: 9 of them had hepaticojejunostomy (hepaticojejunostomy) with a loop of small intestine disconnected according to roux, and 2 patients had hepda applied. for injuries at the “+1”, “0” level, the site for anastomosis was created by dissecting the left hepatic duct, exposing it under the chiliary plate (heppcouinaud method). in 4 cases, when the damage occurred with the destruction of confluence (level “-2”), in order to form a single anastomosis with the jejunum, the platform was created by parallel suturing of the remnants of the lobar ducts along their medial walls, cutting the septum between them (cattell method). after the neoconfluence was formed, both lobar ducts were additionally dissected, which significantly increased the diameter of the future anastomosis. despite the small diameter of the ducts, it was possible to create a platform for anastomosis ranging in size from 10 to 25 mm (≤ 15 mm 3; 16-25 mm 7; ≥25 mm 1). in 2 patients, hepea was placed on transhepatic frame drainage (tpcd) according to seipol-kurian due to the narrow diameter of the duct. thus, the use of techniques developed during operations for ivs strictures made it possible to perform relatively wide precision anastomoses. reconstructive surgery (rbs) with transection (4) and excision (3) of the cbd and aki was performed in 7 patients. regional wound of the

after reconstructive and restorative operations. repeated surgical interventions were required in 33 (32.03%) patients. conclusion in recent years, the number of cholecystectomies has increased markedly and most of them are performed laparoscopically (according to our data more than 80%). the number of ivs injuries has also increased, and these injuries are particularly severe, since in addition to the high bifurcation mechanical trauma, the thermal effect on the duct wall is added. the best results were obtained in patients where operations were performed upon intraoperative detection of ivs injuries (in 84.3% of patients). but unfortunately, intraoperative detection of ivs injuries occurred in 27.2% of cases. in a significant proportion of patients, bile duct injuries are diagnosed late (according to our data in 72.8%), after the development of bile peritonitis or obstructive jaundice. because of this, most patients had to undergo external drainage of the bile ducts at the first stage, missing the opportunity to normalize bile flow immediately after injury. we believe that if damage to the ivs is detected in the immediate postoperative period against the background of peritonitis, subhepatic abscess, or bile leakage, at the first stage it is advisable to limit ourselves to external drainage of the biliary tract. it is advisable to perform reconstructive surgery after the inflammatory-infiltrative process subsides in 2-3 months. this tactic was justified in 30 (73.1%) patients in this group. our experience has shown that the main operation for complete transection and excision of the ivs is hepea according to roux-en-y: a good long-term result was obtained in 97.01% of patients. hepea without frame drainage significantly reduces the treatment time for patients, however, we were able to use the hepp– couinaud method only in 11 patients in this group. the peculiarity of this operation is the isolation of the left hepatic duct at its confluence with the right duct under the portal plate. this makes it possible to isolate the ducts outside the scar tissue and apply an anastomosis up to 2-3 cm wide, mainly due to the left hepatic duct, avoiding long-term (up to 1.5-2 years) drainage of the anastomosis zone, which is burdensome for the patient. restorative surgery is indicated only for partial marginal damage to the duct. in 11 patients of this group, by suturing the duct defect on the kera drainage, we achieved a satisfactory result. when the duct is injured, in contrast to its complete intersection, good results are explained by the fact that the integrity of the narrow posterior wall of the duct ensures sufficient blood supply. the formation of the bba during the intersection and excision of the duct in all 17 cases resulted in the formation of a scar stricture: 14 patients underwent reconstructive surgery, 3 endoscopic stenting. our, https://doi.org/10.37547/ajbspi/volume03issue03-01

stenting allows us to positively evaluate this method. operations during which an anastomosis of the damaged duct with the duodenum was formed had a negative impact on the results of treatment. these patients developed chronic cholangitis and stenosis of the bda, which required repeated reconstructive operations in 2 cases and endoscopic intervention in 9 cases. references 1. akbarov m.m.,

acids in the human body, acting as fundamental nutrients for synthesizing all proteins. besides contributing to brain function, including intellectual activity, motivation, and general mental state, amino acids play a vital role in maintaining overall well-being. these nutrients are key components of all human tissues, such as muscles. amino acids and chemical elements not only exhibit specific pharmacological effects but also demonstrate synergism with various substances, paving the way for the development of combined drugs with multiple functional properties derived from plants. importantly, macro and micronutrients, as well as amino acids sourced from plants, are more effectively absorbed by the human body, owing to their “biological” quantities present in plants. furthermore, amino acids assist in the optimal performance of mineral substances within the human body. the study of amino acid and mineral compositions in medicinal plants and phytopreparations is vital for the creation of new pharmaceutical drugs [4]. currently, it's essential to understand the trace element content in the entire body of medicinal plants, including their separate generative and vegetative organs roots, stems, leaves, buds, flowers, fruits, and seeds. this knowledge significantly expands the scope of their utilization. in plants, bioelements are found in forms that are absorbable by the human body, such as amino acids, vitamins, proteins, etc., and they are present in complex forms. this fact underscores the importance of medicinal plants as sources of biologically active substances and elements. the investigation of the elemental composition of medicinal plants and their based preparations is not only necessary for determining their value but also for preventing toxic and carcinogenic properties due to increased levels of heavy metals and arsenic [5,6]. considering the above, the feasibility of using medicinal plant raw materials or extracts based on them in healthcare practice involves studying their amino acid and elemental composition. amino acids are crucial for plant development, occurring during photosynthesis and participating in a wide range of biochemical reactions that support optimal growth and development [7,8,9]. object of the study: the aim of this study is to investigate the amino acid and elemental composition of the dry extract of “hyposedaf”. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 01-2024 104 american

publisher: oscar publishing services servi experimental part: the research focused on the dry extract of “hyposedaf”, conditionally named and derived from various plant raw materials, including peppermint leaves (folia menthae piperitae l.), turkistan lion's tail grass (herba leonuri turkistanicae), dark-red hawthorn fruits (fructus crataegi sanguineae pall), and field horsetail grass (herba equiseti arvensis). this extract complied with the specifications outlined in the publications state pharmacopoeia of the russian federation and xiv state pharmacopoeia (rf) [10,11]. in the first phase of our research, we concentrated on the elemental composition of “hyposedaf” analyzing its macro and microelements through inductively coupled plasma mass spectrometry (icp ms) as per the methodological guidelines [12]. in the second phase, the amino acid composition of the “hyposedaf” dry extract was examined. this involved isolating free amino acids and conducting their quantitative analysis by comparing the retention times and peak areas of a standard sample with those of amino acids obtained from phenylthiocarbamyl. results and discussion: the “hyposedaf” dry extract was analyzed using the highly sensitive inductively coupled plasma mass spectrometry (icp-ms) method. this technique enabled the simultaneous determination of numerous elements in a single sample with very low detection limits. the massspectral analysis was developed in russia and validated in uzbekistan (mbi) uzo`u 0677:2015 (mbi №499aem/ms), facilitating the determination of 61 elements (na, mg,

measurement, the sample underwent solubilization. the resulting solution, containing the test sample, was aerosolized with a stream of argon and introduced into the plasma. the core temperature of the plasma reached up to 9000°c, at which the sample was desiccated, and the molecular elements transitioned to an atomic state, becoming ionized to form positive ions. these positive ions, along with electrons and neutral particles, were channeled through coneshaped interfaces into the vacuum segment of the analyzer, passing through several electric ion lenses that filtered out electrons and neutral particles from the ions. the test sample and a standard sample, each weighing 0.1 g, were placed in teflon bags. decomposition of the test, standard, and control samples was performed in a system involving teflon bags with lids (hot block, environmental express). the hot block, consisting of 36 or 40 cells depending on the model, allowed for the heating of dissected samples in large volumes. this decomposition process utilized a mixture of hf, hclo4, and hno3 acids in an open system to fully dissolve the test sample. after removing the bags from the heating

amounts of elements crucial for human life, such as potassium, calcium, phosphorus, magnesium, sodium, aluminum, iron, etc. literature suggests that potassium compounds are vital for muscle contraction and brain function, and their deficiency can lead to fatigue and overall body weakness. magnesium is an essential element found in all body tissues, crucial for the normal functioning of cells. it holds particular importance for internal organs, especially the heart and blood vessels. calcium compounds present in the analyzed dry extract are key microelements for human life and health. in medical applications, they serve as sedatives, hemostatics, treatments for allergic diseases, and blood pressure regulators. calcium is key in strengthening the skeletal system, forming tooth enamel, and plays significant roles in the immune system, skin, hair, nail health, and reproductive function. it is also instrumental in enhancing metabolic processes within the body. the high concentration of sodium compounds in the dry extract, combined with potassium, aids in maintaining acid-base balance, osmotic concentration of blood, activation of numerous enzymes, and contributes to the formation of membrane potential. therefore, the “hyposedaf” dry extract can be regarded as a valuable source of both macro and microelements. according to normative documents, the content of heavy metals and arsenic in plants and their derived medicinal preparations is in compliance with the standards of xiv state pharmacopoeia and sanitaryepidemiological rules and norms. it has been verified that these concentrations do not exceed established limits. the obtained results are presented in table 2. table 2 amount of heavy metals and arsenic in dry extract of “hyposedaf” mkg/g

process involved isolating free amino acids. for this, 1 ml of the test sample was combined with an equal volume (1 ml) of 20% trichloroacetic acid. after a duration of 10 minutes, the resultant precipitate was separated through centrifugation at a speed of 8000 revolutions per minute for 15 minutes. subsequently, 0.1 ml of the clarified liquid was isolated and subjected to lyophilization. the hydrolyzate was then evaporated, and the dry residue was dissolved in a triethylamineacetonitrile-water mixture (ratio 1:7:1) and dried again. the amino acid phenylthiocarbamyl derivatives (ftc) were synthesized using the phenylisothiocyanate reaction, following the methodology of steven a. and koen daniel. the identification of these amino acid derivatives was carried out via high-performance liquid chromatography (hplc). employing an agilent technologies 1200 hplc column detector (75x4.6 mm), we utilized solution a: 0.14m ch3coona with 0.05% tea at ph 6.4, and solution b: ch3cn. the flow rate was maintained at 1.2 ml/min, with detection at 269 nm. the gradient percentage per minute was established as follows: 1-6%/0-2.5 min; 6-30%/2.51-40 min; 30-60%/40.1-45 min; 60-60%/45.1-50 min; 600%/50.1-55 min [13]. the chromatographic analysis of both the standard amino acid sample of the “hyposedaf” dry extract and the amino acids present in the extract under study are depicted in figures 1 and 2. table 3 presents the quantitative composition and chemical structure classification of the amino acids. according to the data in table 3, the “hyposedaf” dry extract contains 20 amino acids, including 10 essential amino acids, which highlight its substantial quantity and pharmacological significance. the total amino acid content is 29.151 µg/g, of which 15.605

predatory fish and their species. keywords fish, predatory fish, structure, lifestyle, ecological characteristics. introduction fish (pisces) is a large class of the vertebrate subtype, very common. the structure, life and ecological characteristics are very well adapted to the aquatic environment. the ancient ancestors of fishes were chordates with a simple lanceolate structure. in the course of historical development, animals with pairs of fins appeared from the first chordates. they lived a wild life. as a result of living an active life in search of prey, their nervous system and sensory organs developed and fishes appeared. fish are chordate animals that live in water. the body is compressed from both sides, covered with scales, has three odd, two pairs of fins. he breathes through jabra. the heart has two chambers, the circulatory system consists of one circle, and the nervous system consists of the brain and spinal cord. fish sense organs consist of eyes, ears, nose, whiskers and side stripes. a fish cannot see far. he sees things a meter away. but due to the shrinking of the sickle cell, he can see up to 12 meters away. the hearing organ of fish consists of the inner ear. because the water is in a dense environment, fish hear very well. he can even hear footsteps on the shore. like all animals, he has a strong sense of smell. some fish also have whiskers. a mustache acts as an emotion. the research article biological and ecological significance of predatory fish submission date: may 02, 2024, accepted date: may 07, 2024, published date: may 12, 2024 crossref doi:

side lines. predatory fish. predators of the underwater world include fish, their diet includes other inhabitants of water bodies, as well as birds and some animals. the world of predatory fish is diverse: from scary specimens to attractive aquarium specimens. they combine their large mouth with sharp teeth to catch prey. a characteristic feature of predators is unrestrained greed, excessive satiety. ichthyologists note the special intelligence and inventiveness of these creatures of nature. the struggle for survival contributed to the development of abilities predatory fish surpass even cats and dogs. sea predatory fish. most of the marine fish of predatory families live in the tropics and subtropics. it is in these climatic zones that there are many different herbivorous fish, warm-blooded mammals that make up the diet of predators. shark. takes implicit leadership white predatory fish is the trickiest for people. the length of the carcass is 11 m. its 250 species of relatives can also be dangerous, but the attacks of 29 representatives of their families have been officially recorded. the safest is the whale shark huge, up to 15 m long, feeds on plankton. than 1.5-2 meters are tricky and dangerous. among them: • tiger shark; • hammerhead shark (there are large protrusions with eyes on the head of the side); • shark mako; • katran (sea dog); • gray shark; • spotted shark scillium. in addition to sharp teeth, fish are equipped with barbed spines and tough skin. cuts and blows are as dangerous as bites. injuries caused by large sharks are fatal in 80% of cases. the power of the jaws of predators reaches 18 tf. with a bite, it is able to dismember a person. the unique abilities of sharks allow them to catch the water vibrations of a swimming person at a distance of 200 m. the inner ear is tuned to infrared and low frequencies. the beast senses a drop of blood at a distance of 1-4 km. vision is 10 times sharper than humans. the speed of acceleration

chasing the prey. barracuda (seiren). the length of this population, similar to large peaks, it reaches 3 meters. the lower jaw of the fish is pushed forward, which makes it especially scary. silver barracudas are sensitive to bright objects and water vibrations. large predatory fish can bite a diver's leg or cause injuries that are difficult to heal. sometimes these attacks involve sharks. barracudas are nicknamed sea tigers for their sudden attacks and sharp teeth. they feed on everything, ignoring even poisonous people. gradually, toxins accumulate in the muscles, making fish meat unhealthy. small barracudas hunt in schools, large singly. swordfish. a sea predator with a length of up to 3 meters and a weight of 400-450 kg. the unique appearance of the fish is reflected in the name of the fish. the long growth of the upper jaw bone resembles a military weapon in its structure. a type of sword up to 1.5 meters long. the fish itself looks like a torpedo. a swordsman's punch is more than 4 tons. it easily penetrates a 40 cm thick oak board and a 2.5 cm thick metal sheet. the beast has no scales. despite its water resistance, the travel speed is up to 130 km/h. this is a unique indicator that raises questions even among ichthyologists. the swordsman swallows the prey whole or cuts it into pieces. there are many fish in the diet, including even sharks. monkfish (european monkfish) the resident at the bottom expands. it got its name because of its unpleasant appearance. the body is large, about 2 meters long, weighing up to 20 kg. noteworthy is the crescent-shaped mouth with an extended lower half-jaw and close-set eyes. natural camouflage reliably camouflages the predator during hunting. a long fin on the upper jaw serves as a fish catch. in its formation, bacteria live as bait for fish. the angler must watch for prey near his mouth. monkfish can swallow prey several times larger than itself. sometimes it rises to the surface of the water and catches birds that have fallen to sea level. sargan (arrowhead fish). in appearance, teaching sea fish can easily be confused with needle fish or embroidery. the silver body is 90 cm long. sargan lives near the water level of the southern and northern seas. long, narrow jaws protrude forward. the teeth are small and sharp. it feeds on sprat, mackerel, gerbil. in pursuit of the victim, it quickly jumps through the water. a noteworthy feature of the fish is the green color of the bones. night. a large school predator common in the atlantic ocean. carcass reaches 4 meters, weighs half a

within. the epithelium's basement membrane is relatively colorless and thin. van gieson staining shows that the alveolar space, which separates the alveoli, is lined with solitary neutrophils, tissue basophils, macrophages, and thin yellow connective tissue fibers. near the alveolar epithelial membrane are several capillaries in the alveolar spaces that are somewhat blood-filled. these capillaries are lined by endothelial cells that have rounded basophilic nuclei and slightly basophilic cytoplasm. little clusters of lymphoid tissue surround the vessels. conclusions data obtained from histological and histochemical examination of fragments of the bronchial wall taken from patients who died without respiratory diseases can be used as a basis for direct comparison with changes occurring in the bronchial wall of patients who died from respiratory diseases. references 1. zavaliy m.a. comparative histology and physiology of the ciliated apparatus of the respiratory epithelium

analysis of the objects under study, study the physical and chemical properties of substances, and monitor and automatically regulate technological processes. gas chromatography is a method for separating volatile compounds. this method can analyze gaseous, liquid and solid substances with a molecular weight of less than 400 that satisfy certain requirements, the main ones being volatility, thermal stability, inertness and ease of preparation. quantitative analysis can only be carried out if the substance is heat-resistant, i.e. evaporates reproducibly in the dispenser and elutes from the column without decomposition (1,7). in pharmaceutical analysis, the glc method is widely used to determine residual organic solvents in pharmaceutical substances, biological active substances in liquid and dry extracts of medicinal plant materials, as well as in assessing the quality of essential oils, volatile medicinal substances, and their preparations (2,5,6). the purpose of our work is to study the quantitative content of biological active substances in a dry extract obtained from plant raw materials of saffron using gas-liquid chromatography. previously, we studied the qualitative content of biologically active substances in plant raw materials of saffron using gas chromatography-mass spectroscopy (3). for the quantitative determination of biologically active substances in the dry extract of saffron, we used the dry extract we had previously obtained by the percolation method (4). experimental parts. quantification method: gas chromatograph – khromatek-kristall – 5000

gn exacerbation, in particular, in the urinary (hidden) form of the disease, due to the lack of clear criteria for their diagnosis. there are works dedicated to the study of biomarkers of glomerulonephritis chronicity [1, 3, 7]. at the same time, the role of proand anti-inflammatory cytokines in maintaining the inflammatory process in glomerulonephritis of various clinical courses has not yet been determined. in relation to the above, the aim of this study was to investigate the circulating levels of cytokines in patients with acute and chronic gn. methods this study included 55 patients with gn aged 10 to 18 years who were treated in the nephrology department at children's city hospital no. 1 in samarkand. at the beginning of the disease, 10 patients (acute gn), with exacerbation of chronic gn 45 patients were studied. diagnostic nephrobiopsy was performed in 34 patients, mesangioproliferative variant of gn was detected in 21 cases, membranoproliferative variant in 6 cases, membranous in 6 cases, and gn with minimal changes in 1 case. there are 24 girls and 31 boys among those who passed the examination. groups of patients with acute gn and chronic gn were representative of patients with different morphological variants of the disease and representative of the functional status of the patients' kidneys. in addition to the generally accepted studies (general clinical blood and urine tests, biochemical studies creatinine, urea, bilirubin, transaminases, hemostasiogram, proteinogram, creactive protein, glomerular filtration rate, tubular

interferon-y (ifn-y) and il-1b receptor antagonist ra -il-1b. the object of the study was venous blood serum. blood tests were performed twice at admission to inpatient treatment (on days 2-3) and at the end of the period of inpatient treatment (on days 12-14). the following parameters of descriptive statistics were determined: arithmetic mean (m), standard deviation (sd). when comparing two

which has regulatory functions, and their values are at the reference level. during gn, the increase in the production of proinflammatory cytokines is explained by the development of inflammatory changes in the glomeruli as a result of infiltration by lymphocytes, monocytes and the increase of resident glomerular cells [5]. an increase in the production of anti-inflammatory cytokines il-10 and ra-il-1b, which occurs in parallel with an increase in the level of pro-inflammatory cytokines, can be considered as an autoregulatory reaction aimed at suppressing the increase in production,

treatment with acute gn was 1.6 times higher than that of the group of sick patients. despite the fact that the average amount of il-1β in patients with chronic gn was 4.7 times lower than the corresponding value in patients with acute gn, the difference between the level of production of this cytokine in the compared groups of patients was statistically not important. comparison of cytokine levels before and after treatment using the wilcoxon test revealed certain dynamics of cytokine production levels during treatment in patients with acute gn, with a decrease in the initial high levels of il-1β, rα-il-1β and il-2 appeared. the level of ifnγ was also significantly decreased (pw<0.05), its baseline level was not different from the corresponding reference values. no significant dynamics in the production of cytokines were observed during treatment in patients with chronic gn. in connection with the known situation about the mutual dependence of the production of individual cytokines, we investigated the correlation relationship between the levels of the studied cytokines. in healthy people, only one correlation was established between the indicators of cytokine status a negative correlation of the levels of anti-inflammatory cytokines il-10 and ra-il-1b (rs = -0.76; prs = 0.030). being with the development of glomerular kidney damage, the total number of connections increased significantly. cytokine profile of patients with chronic gn including pro-inflammatory cytokine il-1β and its receptor antagonist, pro-inflammatory cytokines il-2 and ifnγ, pro-inflammatory cytokine ifnγ and pro-inflammatory cytokine il-10 baseline characterized by the existence of a direct relationship between internal levels. relationships established at the end of treatment were also observed. in addition, by the end of treatment, a new correlation was found between il-2 and il-10 levels. the correlations found in patients with chronic gn suggest the interaction of pro-inflammatory and anti-inflammatory cytokine production. this, the results of the correlation analysis show that there is a correlation between only pro-inflammatory cytokines in healthy individuals. the relationships identified in the acute form of gn reflect the interdependence of the production of proinflammatory cytokines. a close relationship between the levels of pro-inflammatory and anti-inflammatory cytokine production during the period of exacerbation of chronic gn is revealed. in addition, by the end of chronic gn exacerbation relief, the number of such connections increases, in patients with acute gn, by the end of inpatient treatment, no correlation is found in the level of studied cytokines. in connection with the differences in the levels of rαil-1β and ifnγ detected in patients with acute and chronic gn, it is noteworthy that these cytokines correlate with the indicators of a set of standard

exacerbation of chronic gn from the onset of the disease [1]. we found that the absolute number of neutrophils and the relative number of eosinophils determined before treatment of a patient with gn can be used to distinguish the nature of the clinical course of gn. contrary to expectations, immunological indicators were not suitable for use as diagnostic criteria to determine the nature of the clinical course of gn: we could not find differences in innate and adaptive immune response indicators in groups of patients with acute and chronic diseases in patients with gn, a different situation occurs according to the results of the study of the cytokine profile: the exacerbation of chronic gn is distinguished from the onset of gn by a smaller increase in the level of anti-inflammatory cytokine ра-il-1b, the characteristics of which are 595 percentile interval from 111 to 3915 pg/ml (in patients with acute gn from 395 to 2942 pg/ml) and high levels of pro-inflammatory cytokine ifnγ are distributed, at the end of treatment from 26.7 with changes up to 412.4 pg / ml (in patients with acute gn from 24.1 to 45 pg / ml). therefore, determination of the levels of rα-il-1β and ifn-γ can be used to distinguish between acute and chronic gn: a baseline rα-il-1β level below 395 pg/ml in a patient with gn is concentration increases the probability of diagnosis in favor of chronic gn with the presence of other symptoms of chronic gn. in this case, if the level of ifn-γ is higher than 45 pg / ml, the diagnosis of chronic gn can be confirmed by the 14th day of hospital treatment. conclusion 1. differences in the cytokine profile in patients with gn were determined depending on the clinical course of the disease. 2. in the acute period of gn, a direct correlation was found in the levels of production of pro-inflammatory cytokines, which disappear until the end of hospital treatment. the chronic course of gn is characterized by the presence of interdependence in the production of pro-inflammatory and anti-inflammatory cytokines. 3. cytokine profile of patients with exacerbation of chronic gn is characterized by low initial level of circulating ра-il-1b and high level of ifn-γ by the end of the inpatient treatment course. 4. the initial concentration of ra-il-1b at hospitalization of a patient with gn below 395 pg / ml increases the probability of diagnosis in favor of chronic gn. references 1. alchinbaev m. k., sultonova b. g., karabaeva a. j. surunkali pielonefrit bilan og'rigan bemorlarda funktsional buyrak zaxirasi. // nefrologiya. 2001. 5jild,

responding as effectively to stimulation [1]. a decrease in the activity of stem cells leads to the fact that the rate of skin renewal slows down and defects begin to accumulate in it; the skin ages [2]. recently, the attention of scientists has been attracted by plant stem cells, which produce a complex of molecular regulators that are universal. these regulators are capable of changing the functioning of human skin stem cells, partially returning them the energy of youth [3]. one of the most popular ingredients today is swiss apple stem cells. each adult apple stem cell can independently generate new cells and, in a concentration of just 0.1%, stimulate the division of human stem cells by 80% [4]. phytostem (plant) cells were discovered relatively recently only in the

skin disease with a complex pathogenesis, involving genetic predisposition, immunological and epidermal barrier dysfunction, and environmental factors [7]. the main symptom is pruritus; skin lesions range from mild erythema to severe lichenification and erythroderma. a thorough history and narrow examinations are required to make a correct diagnosis. treatment includes recommendations for proper skin care, avoidance of triggers, and topical use of corticosteroids and immunosuppressants. treatment of itching and superinfections is also important. in severe cases, systemic immunosuppressive therapy may be required [8]. atopic dermatitis that develops in childhood often regresses or its manifestations significantly weaken in adults [9]. for symptoms of atopic dermatitis, treatment and selection of the optimal way to combat the disease should be carried out under the supervision of a physician [10]. however, cell therapy in this case is most effective. this treatment method is characterized by a large number of advantages and allows to achieve the effect as quickly as possible without the development of any side effects or complications [11]. stem cells primarily harmonize the activity of the immune system. and this ensures a significant reduction in the patient’s tendency to develop allergies. in addition, this method allows you to renew the cellular composition of all layers of the skin, which leads to minimizing the severity of external manifestations of dermatitis [12]. the purpose of the work was to study the clinical effectiveness of drugs containing stem cells

form of non-alcoholic fatty liver disease (nafld), which includes a wide range of conditions: from non-alcoholic steatosis (nas) fat deposition in the liver of more than 5% of the parenchymal mass without signs of damage to hepatocytes to non-alcoholic steatohepatitis (nash), which progresses with development fibrosis, cirrhosis and, in some patients, hepatocellular carcinoma [1]. the prevalence of steatohepatitis in the pediatric population, according to various sources, varies greatly. thus, the recommendations of the north american society of pediatric gastroenterologists, hepatologists and nutritionists (naspghan) indicate that hypertransaminasemia occurs in 29-38% of obese children aged 2-4 years [1]. according to a. sahota et al. [2], nash was found in 12% of obese and overweight children. the joint recommendations for the diagnosis, treatment and prevention of obesity in children and adolescents of the russian association of endocrinologists, the russian society for the prevention of non-infectious diseases, and the association of pediatric cardiologists of russia note that nash is diagnosed in 1226% of obese children and

on these data, it can be assumed that the incidence of nash in the pediatric population varies from 0.5 to 3%. it should be noted that the prevalence of obesity, and with it nafld, including nash, is increasing throughout the world due to modern negative trends in the diet and physical activity of children [7]. keywords population, hepatocytes, non-alcoholic steatosis (nas), non-alcoholic fatty liver disease (nafld). introduction pathogenesis the pathophysiology of molecular abnormalities in nash is complex and multifactorial. metabolic imbalances that result in fat deposition in the liver are associated with three mechanisms (see figure) [8]: an increase in the amount of free fatty acids entering hepatocytes due to increased dietary fat intake or quantitative/qualitative disturbances of the intestinal microbiome; • an increase in the supply of free fatty acids to hepatocytes from the non-esterified pool, the source of which is white adipose tissue; • activation of de novo lipogenesis in the liver, the cause of which is associated with excess carbohydrates and/or hyperinsulinemia due to the resistance of adipose tissue to insulin. accumulation of triglycerides and free fatty acids in hepatocytes occurs when these processes are not compensated by increased production of very lowdensity lipoproteins in the liver [8]. it is generally accepted that lipotoxicity is associated with the accumulation in hepatocytes not of triglycerides, but of free fatty acids and their metabolites [8], leading to oxidative stress and subsequent damage to intracellular structures (mitochondria, endoplasmic reticulum). these changes cause a cascade of reactions, including the release of reactive oxygen species, il-6, -10, -18, tnf-α, ifn-γ by hepatocytes and the recruitment of immune cells (plasmocytes, lymphocytes) [8]. these processes culminate in hepatocyte damage, progressive inflammation, programmed cell death (apoptosis), and fibrotic remodeling of the liver through collagen deposition from activated stellate cells [8]. in recent years, the pathogenesis of nas and nash has been linked to changes in the gut microbiota that lead to bacterial translocation, especially of a highly immunoreactive gram-negative cell wall component called lipopolysaccharide (lps), into the systemic circulation, which further enhances the inflammatory process by activating macrophages and kupffer cells. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 03-2024 26

publisher: oscar publishing services servi it has been established that changes in the intestinal microbiota in patients with nafld are associated with the genes k01470, k01961, k07258 and are manifested by disruption of the pathways of arginine and proline metabolism, fatty acid synthesis and polysaccharide biosynthesis and metabolism [9]. in addition, these three functional genes were associated with significant disturbances in the intestinal microbiome a decrease in the number of bacteroides, bifidobacterium, ruminococcus and an increase in prevotella, which shows the possibility of the influence of disturbances in the intestinal flora on changes in lipid metabolism due to differential expression of genes contributing to the pathogenesis of nafld, including. h. nash [9]. overfeeding of children in infancy leads to excess body weight in the future, which, in turn, can predetermine the development of nafld. an experimental study in rats showed that overfeeding rats aged 3-13 weeks caused excess glucocorticoids through activation of the enzyme 11β-hsd1 (11β-hydroxysteroid dehydrogenase type 1) in the liver, which, in turn, activated de novo hepatic lipogenesis through glucocorticoids. receptors, which led to lipid accumulation in the liver, increased the risk of nafld in adulthood [10]. in research, great importance is given to the analysis of genetic predisposition to obesity and nash. a significant role in the occurrence of nash belongs to the pnpla3 gene, encoding the triacylglycerol lipase protein, which is involved in lipid metabolism and promotes the accumulation of lipid molecules in hepatocytes; an association of pnpla3 polymorphism with increased alt levels and a more frequent occurrence in obese children of different ages with metabolic syndrome has been established [11]. the tm6sf2 gene, encoding superfamily 2 transmembrane protein 6, promotes the formation of excessive amounts of very low density lipoproteins in hepatocytes, which leads to the accumulation of triglycerides in liver cells [12]. the role of the akr1d1 gene, encoding steroid 5β-reductase, variants of which increase the accumulation of triglycerides in hepatocytes, insulin sensitivity and glycogen synthesis by increasing de novo lipogenesis and reducing βoxidation, activating hepatocyte inflammation, has also been noted [13]. there is an association between the mthfr 677ct gene variant and the level of homocysteine as a component of oxidative stress in patients with nafld [14]. other genes that are important in the development of nash and progression to steatofibrosis have also been identified [12]. the role of vitamin d in the pathogenesis of nafld is being studied. in the work of m. kong et al. it has been demonstrated that a high-fat diet deficient in vitamin d interferes with the enterohepatic circulation of bile acids, leading to nash [15]. it has also been shown that vitamin d deficiency can increase adipose tissue dysfunction and, in particular, cause an increase in the production of cytokines (tnf-α, il-1β, il-6), which https://doi.org/10.37547/ajbspi/volume03issue03-01

volume 04 issue 03 pages: 24-35 sjif impact factor (2022: 5. 705) (2023: 6.534) (2024: 7.7) oclc – 1121105677 publisher: oscar publishing services servi contributes to the progression of nafld [16]. it was shown that in children with nafld, significant liver fibrosis (stage ≥ 2 by ultrasound) was detected in 29% with vitamin d deficiency (serum 25(oh)d concentration 21-30 ng/ml) and in 17% with normal vitamin levels [17]. diagnostics laboratory diagnostics diagnosing nash in children, as well as nafld in general, is not difficult. according to the recommendations of espghan (2012), the examination and differential diagnosis plan for children with nafld should include the following laboratory tests [4]: • clinical blood test, determination of glycemic levels, fasting insulin, urea, electrolytes, coagulogram; • analysis of biochemical indicators of liver condition aspartate aminotransferase (ast), alanine aminotransferase (alat), alt/ast ratio, γ-glutamyl transpeptidase (ggtp), total bilirubin and its fractions; • lipid profile cholesterol, triglycerides, high-density lipoproteins (hdl), low-density lipoproteins (ldl); • oral glucose tolerance test, glycated hemoglobin (hba1c); • determination of the homa-ir and isi-gly indices as indicators of insulin resistance; • assessment of the functional state of the thyroid gland; • exclusion of wilson's disease concentration of ceruloplasmin, copper in the blood serum, urinary copper excretion per day; • exclusion of cystic fibrosis sweat test; • exclusion of celiac disease antibodies (iga) to tissue transglutaminase, total iga; • other tests in accordance with the medical history exclusion of viral hepatitis, autoimmune liver diseases (liver autoantibodies), serum immunoglobulins. the currently recommended test for screening for steatohepatitis is the determination of alt activity [1, 18]. nash is more often found in children with alt ≥ 80 u/l compared with children with enzyme activity < 80 u/l (41% and 21%, respectively). if the alt level is > 80 u/l for ≥ 3 months, clinical data should be assessed, since such an increase in enzyme activity may indicate existing hepatocyte damage [18]. in the absence of risk factors for the development of nafld (excessive weight gain, type 2 diabetes mellitus, obstructive sleep apnea), alt activity is recommended to be tested every 2-3 years [1]. in the presence of these risk factors, it is recommended to repeat the alt test in blood serum [1], the frequency of repeat testing is not defined in international recommendations, the issue is resolved individually. a number of studies have shown that overexpression of hif-2a (hypoxia-inducible factor) [19], visfatin [20, 21], increased concentrations of c-reactive protein, apolipoprotein a1, haptoglobin and α2-macroglobulin [22], fibroblast growth factor 21 [23], adiponectin and adiponectin receptor 2 [24] are https://doi.org/10.37547/ajbspi/volume03issue03-01

volume 04 issue 03 pages: 24-35 sjif impact factor (2022: 5. 705) (2023: 6.534) (2024: 7.7) oclc – 1121105677 publisher: oscar publishing services servi associated with the progression of nafld, suppression of fatty acid β-oxidation and induction of lipogenesis in the liver [19]. in addition, the above factors have pronounced lipotoxicity and trigger a cycle of progressive damage to hepatocyte organelles, leading to their apoptosis and aseptic inflammation [25]. inflammation of adipose tissue and intestinal dysbiosis provide substrates for the formation of reactive oxygen species that enhance inflammation [25]. and finally, progression from simple steatosis to nash provides an imbalance between proinflammatory (tnfα-, resistin, il-6) and antiinflammatory (adiponectin) cytokines with the dominant effects of the former [26]. histological examination liver biopsy is a test for the diagnosis and differential diagnosis of steatosis and steatohepatitis and exclusion of other diseases, recommended by espghan and called the reference test in consensus [4]. histological signs of nash are the presence of hepatocytes with fatty macrovesicles and a nucleus displaced towards the membrane, changes in hepatocytes like balloon degeneration, mixed inflammation in the liver lobules [4]. also, when studying liver biopsies, perisinusoidal-pericellular fibrosis along with megamitochondria, acidophilic bodies and glycogenated nuclei may be noted, but are not required for the morphological diagnosis of nash. liver biopsy cannot be widely used due to its invasiveness and the risk of complications in both adults and children. there are no specific recommendations for selecting children for this study in international guidelines; in fact, it is indicated for all patients with nash. the high cost (according to our estimates, in russia 12,000-20,000 rubles) of this diagnostic method is also a problem [1]. instrumental visualization in the instrumental diagnosis of nafld, espghan (2012) recommends the use of ultrasonography, computed tomography, magnetic resonance imaging, and liver fibroscanning [4], which are also appropriate for nash, primarily to identify fibrosis of the liver tissue that occurs along with inflammation. ultrasound diagnostics (ultrasound) is a method of qualitative assessment of the condition of liver tissue, available in most medical institutions. the sensitivity of ultrasound for detecting liver changes in nafld is 6096%, specificity is 84-100% [4]. there is no doubt that the results of ultrasound diagnostics depend on the apparatus and the skills of the doctor performing the examination. however, this method is fast enough to diagnose liver damage the duration of the study is about 20 minutes. the threshold for detecting changes in the liver parenchyma by ultrasound in patients with nafld is the presence of fatty infiltration of ≥ 20% of hepatocytes [4]. to assess the degree of nafld, an ultrasound fatty liver index has been proposed a new scoring system in the range of 2-8 points, based on such indicators as the intensity of ultrasound signals of the liver relative to the kidneys, weakening of the https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 03-2024 29 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 03 pages: 24-35 sjif impact factor (2022: 5. 705) (2023: 6.534) (2024: 7.7) oclc – 1121105677 publisher: oscar publishing services servi ultrasound signal in the retroperitoneal space, unclear visualization of blood vessels, difficulty in visualization gallbladder walls, diaphragm, detection of focal changes in the liver [27]. in a study by h.k. liu et al. an ultrasound fatty liver index score ≥ 6 was a predictor of steatohepatitis in children with nafld, and the authors proposed using this score to predict steatohepatitis in children with nafld without requiring liver biopsy [28]. computed tomography (ct) allows one to assess the presence and degree of fatty infiltration of the liver, i.e. conduct a qualitative and quantitative analysis of the condition of the liver tissue. the sensitivity of ct for detecting liver changes in nafld is 82%, specificity is 100% [4]. moreover, ct makes it possible to identify steatosis with fatty infiltration of more than 30% of hepatocytes [4]. ct scanning is available and performed quite quickly it takes no more than 5 minutes to obtain the result. however, it should be emphasized that this method is associated with ionizing radiation, which limits its use in children. magnetic resonance imaging (mri) also allows qualitative and quantitative assessment of fatty infiltration of the liver. the method is widely available, but still relatively expensive [4]. liver density assessment occurs in t1 mode. the sensitivity of the method for detecting liver changes in nafld is 100%, specificity is 90.4% [4]. an mri requires 10-15 minutes. however, mri has a number of contraindications: the presence of metal elements in the patient’s body, as well as excess body weight, for which the positioning table is not designed. it should be noted that assessment using mri is possible with fatty infiltration of the liver of the 1st degree 5-30% of hepatocytes [4]. 1h-mr spectroscopy magnetic resonance spectroscopy a method that allows you to qualitatively and quantitatively assess the condition of the liver parenchyma. the method is highly expensive (from 5,000 to 15,000 rubles). the study is carried out in t2 mode fat-saturated spectroscopy, measuring the area at the peak of lipid resonance. the sensitivity of the method is 87-100%, diagnostic accuracy is 80-85% [4]. liver elastography allows you to evaluate fatty infiltration of the liver and detect fibrous changes. the method is based on measuring the density of liver tissue through shear wave propagation. the sensitivity of the method for cases of nafld is 81-85%, specificity is 74-78% [4]. the duration of liver elastography is no more than 20 minutes. the test is non-invasive, fast, reproducible [15]. despite its advantages, this method is not widely used in medical institutions due to a shortage of appropriate equipment and is not included in russian standards for examining children. y.d. kwon et al., examining children with obesity (including nas and nash) found fibrosis (liver stiffness > 5.5 kpa) in 30 (51%) of 59 children, while in the group of children without obesity there were cases of fibrosis were not found. the liver stiffness indicator correlated with the activity of ast (r = 0.525), alt (r = 0.594), insulin https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 03-2024 30 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 03 pages: 24-35 sjif impact factor (2022: 5. 705) (2023: 6.534) (2024: 7.7) oclc – 1121105677 publisher: oscar publishing services servi resistance (homa-ir, r = 0.400) and the ast-toplatelet ratio index (r = 0.480) [29]. calculation indices currently, to assess the presence and histological activity of fibrosis, inflammation, steatosis and other processes in nafld and nash, calculated indices are used that take into account the values of biochemical parameters and minimal anamnestic data. these indices have demonstrated their information content and ease of use, but their disadvantage is their high cost (11,000-20,000 rubles). we also note that it was not possible to find information on the diagnostic accuracy of these tests (sensitivity, specificity). the nas scale (nafld activity score, nafld activity scale) is proposed for semi-quantitative assessment of steatosis (in %), lobular inflammation, balloon degeneration, and the stage of fibrosis. thus, the severity and stage of nafld is characterized [4, 30]. for each item on the scale there is a score from 0 to 2 points. a total score of ≥ 5 points allows a diagnosis of nash [4, 31]. the fibromax test takes into account the values of 10 biochemical blood test indicators: alt, ast, ggtp, total bilirubin, α2-macroglobulin, apolipoprotein a1, haptoglobin, total cholesterol, triglycerides, glucose. mathematical algorithms (5 in total) based on the values of these indicators determine such characteristics of the liver condition as: severity of fibrosis with staging (f0-f4) in accordance with the international metavir system (fibrotest); • activity of necrotic and inflammatory processes with determination of degree (a0-a3) also in accordance with the metavir system (actitest); • presence and severity of liver steatosis (steatotest); • presence of alcoholic steatohepatitis in alcohol abusers (eshtest); • the presence of nash in patients with excess body weight, insulin resistance, hyperlipidemia, as well as in patients with diabetes mellitus (nash-test, from the english nash non-alcoholic steatohepatitis) [31]. a shortened version of the fibromax test called fibrotest is also carried out, when only 2 calculation algorithms are used based on the results of mathematical processing of 6 biochemical blood parameters: α2-macroglobulin, haptoglobin, apolipoprotein a1, ggtp, total bilirubin, alt. in this case, the assessment is given only on two scales the severity of liver fibrosis and the activity of the necroinflammatory process in the liver. therapy lifestyle change currently, the main treatments for children with nash, as with other forms of nafld, are a low-calorie diet and physical activity aimed at correcting overweight or obesity. lifestyle modification with dietary changes and increased physical activity is recommended as firstline therapy for all children with nafld/nash [1]. limiting the consumption of sugary drinks is also indicated [1]. in accordance with naspghan recommendations, it is necessary to increase children's https://doi.org/10.37547/ajbspi/volume03issue03-01

intensity and limit time spent on gadgets to 2 hours per day. [1]. the russian association of endocrinologists advises following similar recommendations when treating obese children [3]. special russian recommendations for the treatment of children with nafld and nash have not been developed. drug treatment it is important to emphasize from the outset that naspghan (2017) [1] does not recommend the use of any medications or dietary supplements for the treatment of patients with nafld/nash. in experimental studies on mice with nafld, it was shown that metformin relieves hepatomegaly, steatosis and abnormal aminotransferase activity [32], which was confirmed by the results of some clinical studies [33]. however, subsequent more rigorous clinical studies did not reveal a reduction in histological changes in the liver in patients with nafld during metformin therapy. [34]. according to the results of a randomized, double-blind, placebo-controlled study, treatment with high doses (28-35 mg/kg per day) of ursodeoxycholic acid (udca) for 12 months reduces aminotransferase activity and the concentration of serum markers of fibrosis in adult patients with histologically confirmed nash [35]. a russian observational study noted that after treatment with udca at a dose of 12-15 mg/kg, normalization of liver enzyme activity was achieved in 96% of children with nash [36]. a randomized controlled trial found that treatment with udca and vitamin e for 2 years reduced the activity of ast and alt and the severity of hepatic steatosis in patients with nash [37]. in experimental studies on animal models, in addition, it was shown that udca drugs have, among other things, antifibrotic and antiapoptotic effects [38]. according to the instructions for the use of udca drugs approved by the russian ministry of health, they are indicated, incl. and patients with nash and do not have any contraindications for children, which means they can be used in children at a dose of 10-15 mg/kg per day for 6-12 months or more. however, the effectiveness and safety of udca in children with nafld/nash have not yet been studied in high-quality clinical studies. in the official instructions of the state register of medicines of the russian federation, some preparations of essential phospholipids or their combination with other components of hepatoprotective action indicate fatty degeneration and liver degeneration, and contraindications include children under 3 or up to 12 years of age. therefore, their use in the treatment of nash in children of the appropriate age is possible. however, it should be noted that high-quality controlled studies of the effectiveness and safety of essential phospholipids for steatohepatitis and liver steatosis in children have not been conducted. there is data on the use of various nutritional supplements in the treatment of patients with steatosis and steatohepatitis. a randomized study https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 03-2024 32 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 03 pages: 24-35 sjif impact factor (2022: 5. 705) (2023: 6.534) (2024: 7.7) oclc – 1121105677 publisher: oscar publishing services servi in children showed the effectiveness of a combination of ascorbic acid + vitamin e / ω3-polyunsaturated fatty acids [39], in randomized double-blind placebocontrolled studies in adults δ-tocotrienol [40], in children the probiotic lactobacillus rhamnosus gg [41] , synbiotics [42]. the effectiveness of lactobacillus rhamnosus gg was also confirmed in a russian observational study involving children [43]. the use of ω3-polyunsaturated fatty acids in children also led to relief of the manifestations of nash, which is described in detail in a literature review by s. spahis et al. [44]. the use of these dietary supplements reduced alt activity, body mass index and/or the number of hepatocytes involved in fatty infiltration to varying degrees. conclusion nash, like other forms of nafld, is a common pathology of childhood, which is associated with a steady increase in the number of children with overweight and obesity in the population. unfortunately, due to current dietary trends and a sedentary lifestyle, a decrease in the incidence of nafld cannot be expected in the near future. the exact causes and pathogenetic mechanisms of progression of steatohepatosis to steatohepatitis are not completely clear. however, there is no doubt that recurrent or persistent necrotic and inflammatory changes in the liver will eventually lead to fibrosis. detection of liver damage in children with overweight or obesity should become an additional motivating factor for parents, the child himself, pediatricians and other specialists to intensify efforts to change the patient’s lifestyle. this is the main and effective method of treating nash and nafld in general, and the administration of hepatoprotectors and antioxidants in long courses serves as an addition that can slow down the progression of the pathological process in the liver. references 1. vos mb, abrams sh, barlow se, et al. naspghan clinical practice guideline for the diagnosis and treatment of nonalcoholic fatty liver disease in children: recommendations from the expert committee on nafld (econ) and the north american society of pediatric gastroenterology, hepatology and nutrition (naspghan). j pediatr gastroenterol nutr. 2017;64(2):319-334. doi: 10.1097/ mpg.0000000000001482 2. sahota ak, shapiro wl, newton kp, et al. incidence of nonalcoholic fatty liver disease in children: 2009-2018. pediatrics. 2020;146(6):e20200771. doi: 10.1542/peds.20200771 3. vajro p, lenta s, socha p, et al. diagnosis of nonalcoholic fatty liver disease in children and adolescents: position paper of the espghan hepatology committee. j pediatr gastroenterol nutr. 2012;54(5):700-713. doi: 10.1097/mpg.0b013e318252a13f https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 03-2024 33 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 03 pages: 24-35 sjif impact factor (2022: 5. 705) (2023: 6.534) (2024: 7.7) oclc – 1121105677 publisher: oscar publishing services servi 4. rito ai, buoncristiano m, spinelli a, et al. association between characteristics at birth, breastfeeding and obesity in 22 countries: the who european childhood obesity surveillance initiative — cosi 2015/2017. obes facts. 2019;12(2):226-243. doi: 10.1159/000500425 5. mapping the health system response to childhood obesity in the who european region. an overview and country perspectives. copenhagen: world health organization regional office for europe; 2019. 4 p. available online: https://www.euro.who.int/__data/ assets/pdf_file/0019/401176/childhood-obesityweb.pdf. accessed on june 23, 2021. 6. neuschwander-tetri ba. non-alcoholic fatty liver disease. bmc med. 2017;15(1):45. doi: 10.1186/s12916-017-0806-8 7. ling jr, zhang yj, zhang zh, et. al. specific changes of intestinal microflora in children with nonalcoholic fatty liver disease. zhonghua er ke za zhi. 2018;56(11):850-855. doi: 10.3760/ cma.j.issn.0578-1310.2018.11.011 8. yang f, dai y, min c, li x. neonatal overfeeding induced glucocorticoid overexposure accelerates hepatic lipogenesis in male rats. nutr metab (lond). 2018;15:30 doi: 10.1186/ s12986-018-0272-0 9. flisiak-jackiewicz m, lebensztejn dm. update on pathogenesis, diagnostics and therapy of nonalcoholic fatty liver disease in children. clin exp hepatol. 2019;5(1):11-21. doi: 10.5114/ ceh.2019.83152 10. богомолов п.о., кокина к.ю., майоров а.ю., мишина е.е. генетические аспекты неалкогольной жировой болезни печени // вопросы современной педиатрии. — 2018. — т. 17. — № 6. — с. 442-448.

farmers and retailers, but also pose a serious threat to public health due to the potential presence of mycotoxins. india is one of the world's largest producers of fruits, and yet there is a lack of comprehensive studies on the types and prevalence of fungi associated with spoilage. therefore, the aim of this study was to isolate and characterize fungal species from spoilt fruits in india, and to assess their implications for food safety and management. the results of this study will contribute to a better understanding of the fungal diversity and mycotoxin contamination in indian fruits, and provide valuable information for the development of effective strategies to prevent and control fungal spoilage. method a total of 100 spoilt fruit samples were collected from local markets in india and analyzed using standard microbiological methods. the fruit samples were sterilized, and fungal colonies were isolated on potato dextrose agar (pda) plates. the fungal species were identified using macroscopic and microscopic characteristics, including colony morphology, spore shape, and size. sample collection: spoilt fruits were collected from different markets in different regions of india. fruits showing visible signs of spoilage such as discoloration, mould growth, and softness were selected. fungal isolation and identification: the spoilt fruit samples were surface sterilized using 70% ethanol and sterile water. small pieces of the fruit tissue were then transferred to potato dextrose agar (pda) plates and incubated at 25°c for 5-7 days. fungal colonies were then subcultured onto fresh pda plates to obtain pure cultures. the pure cultures were identified using standard morphological and biochemical techniques, including lactophenol cotton blue staining, microscopy, and pcr-based sequencing of the its region of the rdna. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04

samples were transported to the laboratory under sterile conditions to prevent contamination. each sample was aseptically divided into smaller portions and processed for fungal isolation. surface sterilization of the fruit samples was carried out using 70% ethanol followed by rinsing in sterile distilled water to remove any external contaminants. for fungal isolation, the method of serial dilution was employed. each portion of the fruit sample was homogenized in sterile saline solution, and serial dilutions were prepared. aliquots from appropriate dilutions were spread onto petri plates containing selective fungal growth media such as potato dextrose agar (pda) supplemented with antibiotics to inhibit bacterial growth. the inoculated plates were then incubated at appropriate temperatures (25-30°c) for a period of 5-7 days to allow fungal growth. colonies exhibiting distinct morphological characteristics were subcultured onto fresh media to obtain pure cultures. pure cultures of fungal isolates were then subjected to https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04

microscopic examination for preliminary identification based on morphological features such as hyphal morphology, spore shape, and color. further characterization of the isolated fungal strains was conducted using biochemical tests including catalase, oxidase, and urease tests. additionally, molecular techniques such as polymerase chain reaction (pcr) amplification of the internal transcribed spacer (its) region of fungal rdna were employed for accurate identification of the fungal species. the obtained sequences were compared with sequences available in public databases such as genbank using bioinformatics tools for species identification. the combined results of morphological, biochemical, and molecular analyses were utilized to classify and identify the fungal species responsible for fruit spoilage in the samples collected from various regions of india. results the results showed the presence of various fungal species in the spoilt fruit samples. aspergillus was the most common fungal species identified in 36% of the samples, followed by penicillium (24%), fusarium (16%), and alternaria (14%). other fungal species, including cladosporium and rhizopus, were also identified. the study suggests that the high prevalence of fungal species in spoilt fruits can have significant implications for food safety and management. the results of the study showed that a total of 10 fungal species were isolated from the spoilt fruits collected from various markets in india. these included aspergillus flavus, aspergillus niger, aspergillus fumigatus, penicillium chrysogenum, penicillium citrinum, penicillium expansum, rhizopus stolonifer, alternaria alternata, fusarium solani, and fusarium oxysporum. among these, aspergillus flavus was the most prevalent species, followed by aspergillus niger and rhizopus stolonifer. mycotoxin analysis revealed that 40% of the aspergillus flavus isolates produced aflatoxins, which are highly carcinogenic and pose a significant threat to human health. furthermore, the study also revealed that the fungal species isolated from the spoilt fruits were resistant to multiple antifungal agents, including fluconazole, itraconazole, and voriconazole. these findings highlight the urgent need for effective management strategies to prevent fungal spoilage and mycotoxin contamination in fruits, and the development of new antifungal agents to combat resistant fungal strains. discussion the presence of fungal species in spoilt fruits can have significant health implications for consumers. fungal species can produce toxins, such as mycotoxins, which can cause foodborne illnesses and long-term health effects. therefore, it is essential to implement effective food safety measures, such as good agricultural practices, post-harvest handling, and storage, to https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04

the growth and spread of fungal species in fruits. additionally, the study highlights the importance of proper fruit handling, storage, and disposal to prevent the spread of fungal species. the study provides important insights into the fungal species responsible for fruit spoilage and the potential risks associated with mycotoxin contamination in india. the prevalence of aspergillus flavus in the spoilt fruits is particularly concerning, as it is a known producer of aflatoxins, which are highly toxic and carcinogenic. the detection of aflatoxin-producing isolates of aspergillus flavus in this study highlights the need for stringent monitoring and regulatory measures to ensure food safety and prevent the entry of contaminated fruits into the market. furthermore, the finding that the fungal species isolated from the spoilt fruits were resistant to multiple antifungal agents is a cause for concern. the emergence of antifungal resistance in these fungal species is a growing problem worldwide, and this study provides evidence that it is also a problem in india. this finding underscores the need for continued research and development of new antifungal agents to combat resistant fungal strains. the study also provides important implications for food safety and management. the presence of spoilage fungi and mycotoxins in fruits can pose a significant threat to human health and can result in significant economic losses due to food spoilage. effective management strategies are needed to prevent fungal spoilage and mycotoxin contamination in fruits, including improved storage conditions, implementation of good agricultural practices, and the use of effective fungicides. additionally, regulatory measures need to be implemented to ensure the safety of fruits in the market and prevent the entry of contaminated products. overall, this study highlights the urgent need for improved management strategies and the development of new antifungal agents to combat resistant fungal strains, and underscores the importance of food safety and regulatory measures to prevent the entry of contaminated fruits into the market. conclusion the study identified the presence of various fungal species in spoilt fruit samples in india and highlights the need for effective food safety measures to prevent the growth and spread of fungal species in fruits. the study suggests that

volume 04 issue 06 pages: 8-12 oclc – 1121105677 publisher: oscar publishing services servi clinical pharmacology is a vital discipline within the medical sciences, focusing on understanding the interactions between drugs and the human body to optimize therapeutic outcomes while minimizing adverse effects. this field has undergone significant evolution since its inception, driven by advances in technology, medical knowledge, and regulatory frameworks. in this article, we delve into the historical development of clinical pharmacology, its significance, key roles, and notable achievements. historical development the origins of clinical pharmacology can be traced back to the early 20th century when the need for systematic drug testing and evaluation became apparent. advances in physiology, biochemistry, and molecular biology laid the groundwork for understanding how drugs affect biological systems. the discipline began to take shape with the introduction of randomized controlled trials (rcts) in the mid-20th century, which provided a scientific basis for evaluating drug efficacy and safety. the 1960s and 1970s saw the establishment of formal academic programs in clinical pharmacology, as well as the creation of regulatory bodies like the u.s. food and drug administration (fda) and the european medicines agency (ema), which began to rigorously evaluate new drugs. these developments marked the transition of clinical pharmacology from a predominantly research-focused field to one that also emphasized patient care and public health. significance and role 1. drug development and approval: clinical pharmacologists are integral to the drug development process. from preclinical studies to phase i-iv clinical trials, these professionals assess the pharmacokinetics and pharmacodynamics of new compounds. they also design and interpret clinical trials that test the efficacy and safety of new drugs, thereby playing a crucial role in bringing new therapies to market. 2. optimizing therapeutic regimens: the goal of clinical pharmacology is to tailor drug therapy to individual patients. this includes considerations of dose-response relationships, drugdrug interactions, and the impact of genetic variability on drug metabolism and action. such personalized approaches aim to maximize therapeutic benefits while minimizing risks. 3. regulatory and policy development: clinical pharmacologists contribute to the development of guidelines and policies that govern the use of drugs. their expertise helps shape regulations that ensure medications are safe, effective, and available to those who need them. this includes involvement in pharmacovigilance activities to monitor adverse drug reactions and ensure ongoing drug safety. 4. education and training: clinical pharmacologists are essential educators, providing training to medical students, residents, and https://doi.org/10.37547/ajbspi/volume03issue03-01

understands the principles of rational drug use, fostering a culture of evidence-based medicine. 5. clinical research and innovations: beyond drug development, clinical pharmacologists conduct research to uncover new therapeutic targets, understand disease mechanisms and develop novel treatment strategies. they also explore innovative drug delivery systems and formulations that can improve patient compliance and outcomes. notable achievements 1. precision medicine: advances in genomics and pharmacogenomics have allowed clinical pharmacologists to develop precision medicine approaches. these strategies use genetic information to predict individual responses to drugs, optimizing therapy and reducing the risk of adverse effects. 2. drug safety and pharmacovigilance: the field has made significant strides in detecting, assessing, and preventing adverse drug reactions. innovations in data analytics and real-world evidence collection have enhanced pharmacovigilance systems, ensuring the safety of drugs even after they reach the market. 3. chronic disease management: clinical pharmacology has been instrumental in developing effective treatments for chronic diseases such as hypertension, diabetes, and cancer. these advancements have significantly improved patient prognosis and quality of life. 4. improved therapeutic outcomes: rigorous clinical trials and evidence-based guidelines have led to the optimization of therapeutic regimens. this has resulted in better patient outcomes, particularly in the management of complex conditions like hiv/aids, cardiovascular diseases, and autoimmune disorders. future directions the future of clinical pharmacology holds exciting prospects. areas such as digital health, artificial intelligence, and real-world evidence are poised to revolutionize drug development and patient care. telemedicine, electronic health records, and wearable devices offer new opportunities for remote monitoring and personalized treatment adjustments. moreover, the ongoing integration of pharmacogenomics into clinical practice promises to further refine drug therapy, reducing trial-and-error prescribing and enhancing treatment efficacy. advances in biotechnology, including gene therapies and personalized vaccines, are likely to expand the therapeutic arsenal available to clinical pharmacologists. conclusion clinical pharmacology is a dynamic and essential field that bridges the gap between drug discovery and patient care. through rigorous research, clinical trials, and evidence-based practice, clinical pharmacologists https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 11 american journal of

is the main field of animal husbandry, and its milk and meat sectors have a special place in providing the population with important food products. thick, heavy hides can be obtained from cattle, which can be used to make the best shoes. in addition, a lot of manure is obtained from cattle, which helps to increase the fertility of the land. the development of this sector in uzbekistan is related to the specific characteristics of agriculture, irrigated agriculture has a positive effect on the development of cattle breeding. therefore, cattle breeding is the main direction of animal husbandry in all irrigated regions of uzbekistan. it is not without reason that 70% of the income of livestock products falls on this sector. in terms of milk productivity, cattle surpass all livestock. the fact that the milk yield of cows in the advanced farms of the republic is 4000-5000 kg indicates that there are huge untapped opportunities in this field. milking of 110.5 kg of milk in one night from a cow named ubre blanca in cuba shows that we do not use cows to their full potential. research article the importance of livestock in the economy and their biological characteristics

conditions of each region require selection of its direction and breeds . the unique structure of the gastrointestinal tract of cattle is capable of consuming and digesting coarse and bulky food with a large amount of fiber. therefore, cattle can consume a lot of the above nutrients and give a lot of cheap livestock products with a small amount of feed. while digesting 55-60% of the fiber contained in the diet of cattle, this indicator is 30-18% in horses and pigs. cattle can be fed mainly blue forages during the summer and coarse and succulent forages in the winter. even in the diet of the most productive cows, 75-80% of volume food can be made. the long life of cattle allows them to be used in the farm for many years. some high-value bulls are reported to last 16-20 years, and cows 20-23 years. the main goal is to get more offspring from famous animals. but breeding and goods 10-12 years for cows and 7-8 years for bulls is considered suitable, then they do not justify themselves economically due to the decrease in the productivity and fertility of animals. in uzbekistan, this sector is considered the main sector of animal husbandry and occupies a special place in the production of livestock products. the development of this industry cannot be said to be the same in all regions of the republic. there are more than 6.5 million cattle in the republic, of which more than 2.8 million are cows. on average, 1,600 kg of milk is obtained from one cow in the republic, which indicates that the opportunities in this field are not fully utilized. the average weight of cattle handed over to the state is 259 kg, which cannot be said to be at the level of today's requirements. this figure is 300-350 kg in several regions of the republic. in order to develop cattle breeding in the country , it is necessary to provide cattle with enough food, improve breeding work, and open a wide way for the development of this field in farms of different types of ownership. increasing the production of livestock products, increasing the productivity of animals, production of products food consumption for it is necessary to increase efficiency based on reducing the cost of products based on reduction. in order to develop cattle breeding in the country, taking into account the forms of ownership, it is necessary to improve production processes on the basis of scientific achievements and advanced experiences, in order to improve the production of cattle products in them, milk and beef. issues of demarcation of cattle breeds in the republic determination,

the coming years. does. the quality of herds improvement in limited periods requires the widespread use of recognized bulls, after passing control on the productivity of their progeny, based on the widespread introduction of artificial insemination in farms of all types of ownership. one of the important areas of development of the industry is the problems of proper breeding of young cattle. to do this, it is necessary to drive cows in time, feed and keep cows, organize their birth, and organize the rearing of calves during the milk period and beyond at the standard level. for this purpose, after filling the herd , it is necessary to separate the born calves into groups for meat, and organize their rearing . feeding the female calves specially allocated for replenishing the herd on the basis of separate rations, organizing rational storage and organizing them to be released at the age of 16-18 months when they reach the weight of 340-350 kg, gives the opportunity to fill the herd of cows at the expense of the first born cows. in order to increase the milk productivity of cows, wean them in time before giving birth, arrange rest for cows before giving birth, organize the birth of cows in special departments, and feed them for 90-100 days. (razdoy) should have a special place. organizing feeding of cows based on their live weight and productivity should be the main tool in realizing the potential of cows and milk productivity. increasing the production of beef can be organized in farms of all types of ownership. farms specializing in meat production should be distinguished in this area. in this regard, increasing the number of farms engaged in specialized meat cattle breeding will give positive results. for this purpose, it is possible to organize large and small farms of various types of ownership in the areas where there are natural meadows and pastures. these farms have a number of cattle breeds suitable for the conditions of uzbekistan. to increase meat production, it is necessary to organize the work of proper growing of calves, maturing and fattening of the bodies. during the growing period of calves, it is desirable that their daily weight gain is 600-700 grams, and during the period of growing and fattening bodies, it is 800-1000 grams . ¬can be transferred to sht. transferring fattened bulls and cows to meat after fattening in all farms allows to gain 80-100 kg of additional weight from each head of animal. today's cattle originated from a species that was widespread in the steppes of ancient asia and europe, and was completely destroyed in the 16th century. the species was domesticated in ancient greece before https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 04-2024 37 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 04 pages: 34-40 sjif impact factor (2022: 5. 705) (2023: 6.534) (2024: 7.7) oclc – 1121105677 publisher: oscar publishing services servi 7000 bc . as a result of long-term artificial selection, the body structure and behavior of the species have changed. today there are many breeds of cattle that differ from each other in terms of wool color, productivity, body size, adaptation to local conditions . a cow's baby is called a calf. adult female calves over one year old are called heifers, heifers that have given birth are called cows, and male cattle are called bulls or oxen. cows differ from the ancient type in their docility, fertility, variety of wool color, and familiarity with their owner. cattle are divided into breeds bred for milk, meat and milk-meat according to the nature of their use on the farm. sersut breeds make up the main part of cattle. red steppe, bushuyev, black-ola, and schwitz cows bred in uzbekistan give 3,000-6,000 kg of milk per year. carnivorous breeds are raised mainly for the purpose of producing quality meat ¬. they do not give much milk, but they mature quickly. shorthorn, kazakh white, santa-gertrude, hereford breeds are bred from cows for meat. the average weight of shorthorn cows is 650 kg, and that of bulls exceeds 1000 kg. young bulls gain weight up to 1 kg per day, their weight reaches 450-500 kg at the age of 1.5-2.0 years. cows raised for milk and meat produce a lot of milk and their meat is of good quality. swiss simmental and russian kostroma breeds are bred for this purpose. simmental cows can produce up to 4000 kg of milk per year. the weight of their bulls is 850 kg, and their cows are 550-650 kg. leather is also taken from cattle. leather shoes and leather haberdashery are made from their skin. a variety of drugs, glue, soap and other products used in medicine are made from the waste of poultry houses. in some countries in south asia, bulls are used as work animals for plowing and carting. increase in the number of livestock in uzbekistan.

farming is a branch of animal husbandry that deals with raising sheep and goats. sheep provide valuable raw materials (wool, skin, fur) and food products (meat, milk, fat) for light industry. gazmol, knitted goods, carpets, skins, clothes from fur, cheese and brinza are made from sheep's wool. there are more than 1 billion sheep in the world. sheep originated from mouflon and arhar, which were domesticated 8,000 years ago. their young female is called sovlyk, the male is called a ram, and the newborn is called a lamb. rams are always horned, and sovliks are hornless or have small horns. sheep live 14-15 years, reach sexual maturity at 5-7 months. usually sheep are used for 8-10 years. depending on the product, sheep are divided into breeds that are bred for wool, leather, leather, meat and fat. sheep from which wool is obtained, in turn, are divided into soft-wool, semi-soft-wool, and coarsewool breeds. the wool of soft-wooled sheep consists of a thin and long (8-10 cm) tuft. elegant gazalami are woven from soft wool (ru no). 10-12 kg of wool is sheared from the merino breed of soft wool sheep in a year. merino sheep are bred in the north caucasus, the volga and the south of kazakhstan. coarse-wool sheep's wool consists of wool, tweed and other types of wool. coarse-wool sheep, in turn, are divided into smooth-skinned, dark-skinned, meat-fat, and meat-wool breeds. the romanov breed , distributed in the central inferior region of russia and the urals, gives the best leather. karakol is the skin of 1-3 day old karakol lambs. black skin is more black. there are also blue, brown, brown and other varieties of karakol sheep. the golden and golden skins of the karakol skin are very valuable. the original homeland of karakol sheep is bukhara. in uzbekistan, hisar sheep are raised for meat and fat. the weight of these breeds is 150 kg, the weight of the hips is up to 25 kg. horse breeding is a branch of animal husbandry that deals with raising and using horses.

people have used horses for carrying goods, riding, plowing, threshing grain, and plowing. until recently, cavalry was considered the main fighting force in the army. even now, in remote mountainous areas, horses are used as means of transport and auxiliary labor. horses are also bred for meat and milk and for sports competitions. in addition, horse milk is used to make curative cream, and its blood is used to make curative serum. a newborn horse is called a mare or kulun, a male is called a stallion, a female is called baytal or biya, a twoyear-old horse is called a foal, a three-year-old is called a gonan, and a four-year-old is called a dunon . according to the color of the horse's hair, it is called by the names of torik, straw, ghir blue and others. compared to other farm animals, they are adapted to run faster and have greater traction. their upper and lower jaws have a space between the incisors and the molars. water is transferred from this place. riders control the horse with the help of a bridle. horses live 25 sometimes up to 40 years. conditioned reflexes are formed in them quickly and easily. therefore, he learns quickly. there are more than 250 breeds of horses in the world. breeds differ from each other in body structure and specialization in use. depending on the use, the horse can be saddled (arabian horse, akhaltaka and yovmut horses of turkmenistan ) , a blanket attached to a cart or sled (don and orlov breeds of russia, lakai of tajikistan, karabayir horses of uzbekistan), heavy load ( vladimir, ardenne, braband horses) are divided into breeds. now horse breeding is developing in the direction of breeding, breeding of working horses, productive horse breeding, sport horse breeding. the main task of breeding yearlings is to improve the quality of existing yearling breeds, to breed valuable original and purebred yearling breeds for breeding. the basis of breeding yearlings is stud farms and breeding yearling farms and farms. in uzbekistan, there are horse factories in tashkent, jizzakh and kashkadarya regions. breeding of working horses is carried out in yearling commodity farms under breeding farms. productive breeding consists of meat and dairy breeding. harvesting in this direction is carried out in mountainous and sub-mountainous regions, in karakalpakstan. delicious and high-calorie national traditional dishes (for example, gazi) are made from goat meat, and medicinal qimiz is made from horse milk. the equestrian yearling is engaged in breeding fast, hardy horses for teams participating in national equestrian games, international equestrian sports and olympic competitions. national equestrian games (such as pokkari) prepare the ground for classical equestrian games. in our republic, great attention is paid to horse sports. currently, there are republican https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue

in adolescents, physiological processes, adaptation possibilities. introduction the objective of this work was to establish an objective assessment of the adequacy of the reactions of physiological indicators and the adaptive ability of the body of adolescents, aged 16-17 years, when carrying heavy loads established by the labor code. during the work, pulse and respiration rates were recorded, pulmonary ventilation, oxygen consumption and energy expenditure of the body were determined. before work and during rest, pulse and respiration rates, blood pressure, stroke and cardiac output (according to the starr formula), latent period of the visual-motor reaction, physiological hand tremor, muscle strength and endurance to static stress were studied [4,5] the periods of continuous carrying of weights by adolescents were limited to 20 minutes. this duration of continuous carrying of loads was established by us based on the results of preliminary observations. the study regimen

load was 2 hours (i.e. 1/3 of the working time of adolescents, in accordance with the labor code). a study on the effect of carrying a load of 16.4 kg by adolescents aged 16 was conducted on 24 adolescents. carrying this load caused an increase in the duration of the latent period of the visual-motor reaction throughout the study and especially at the end of the experiment. there was an increase in heart rate by 3544.5%. when analyzing individual data, each subsequent working period occurred with a greater pulse shift than the previous one. pulse pressure increased throughout the study. indicators of external respiration and gas exchange increased by 1.7-2.0 times. the increase in pulmonary ventilation occurred mainly due to increased breathing; there was a disturbance in the rhythm of respiratory movements and breath holding. there was a decrease in muscle strength (by 28% in the right and 35% in the left arm) and endurance to static stress (in the right arm by 52.6%, in the left arm by 56.7%). when carrying a load, all adolescents complained of pain in the muscles of the arms, shoulders and forearm, and often intercepted the load; cyanosis of the hands was noted. during rest and at the end of the study, hemodynamic parameters were not restored within 15 minutes of rest. not all teenagers who carried this load were able to complete the full amount of work. 10 people (41.6%) refused to work during various working periods. in them, a significant lengthening of the latent period of the visual-motor reaction was noted (from 0.66 to 1.25 seconds) and an increase in differentiation disorders. the pulse rate increased sharply towards the end of each working period, and at the time of refusal to work, it increased by 115% compared to the initial one. in recent working periods, there was an increase in breathing with an increasing pulse rate. at the same time, pulmonary ventilation, breathing depth, and oxygen consumption decreased. refusal to work was preceded by signs of severe fatigue: pale face, profuse sweating, cyanosis of the hands, decreased interest in the environment, then the fingers unclenched and the load fell from the hands [1]. due to the fact that the data obtained indicate unfavorable changes in the body, pronounced subjective and objective signs of severe fatigue and refusal to work, we came to the conclusion that carrying a load of 16.4 kg does not correspond to the functional capabilities of the body. in this regard, observations were carried out on 22 adolescents carrying a load of 14 kg. due to the fact that when carrying a load of 14 kg, all adolescents experienced similar unfavorable functional changes, and 6 adolescents refused to work, studies were conducted with a load of 12 kg. the research was conducted on 20 teenagers. they all completed the full amount of work. functional changes in the central nervous system and cardiovascular, respiratory and neuromuscular systems were adequate to the load tolerated and https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 27 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 25-30 oclc – 1121105677 publisher: oscar publishing services servi indicated a moderate load. therefore, we consider it possible to recommend that for adolescents aged 16 years, a load weighing 12 kg as the maximum load to be carried is a load weighing 12 kg, as it corresponds to the functional capabilities of the body. to study the effect of carrying a load of 16.4 kg on adolescents aged 17 years, studies were conducted on 10 subjects. the data obtained indicate that carrying this load does not cause significant functional changes in the neurodynamics of adolescents. on the part of the cardiovascular and respiratory systems, there was a slight increase in shift towards the end of each period, however, by the fifth minute of rest, these functions were restored. changes in gas exchange indicators indicate strictly coordinated activity of the circulatory and respiratory systems [2]. based on the data obtained, we can say that carrying a load of 16.4 kg, established by the labor code, in adolescents 17 years old does not cause adverse changes and, therefore, corresponds to the functional capabilities of the body. thus, as a result of the research, a number of practically important provisions have been established that indicate that experimental modeling of teenagers carrying weights in laboratory conditions (walking on a treadmill with a load in both hands, lowered down) made it possible to detect certain patterns in the dynamics of changes in the functional state of the subjects, depending on their age and the size of the load. a study of the effect of carrying loads of 16.4 kg and 14 kg on adolescents 16 years old revealed unfavorable changes in the functional state of the body of adolescents: pronounced subjective and objective signs of severe fatigue and refusal to work (in 41% of cases). favorable dynamics of performance indicators were observed in these adolescents when carrying a load of 12 kg. a study of the effect of carrying a weight of 16.4 kg by adolescents 17 years old revealed an adequate response from indicators of the functional state of the central nervous system, cardiovascular and respiratory systems, as well as the neuromuscular system. references 1. гуминский а.а.,леонтева н.н. маринова к.в. руководство к

conditions, hygienic information about the health risk factors and condition of those who work with corpses (medical workers, doctors, nurses, paramedics and junior medical personnel) is scarce and incomplete, which determined the relevance of the research. the purpose of the study. to study the effect of microclimatic factors on temperature in the work process of samarkand region forensic medical expertise employees and to develop preventive measures. it is to eliminate negative factors that may occur as a result of temperature changes. methods the temperature of the microclimatic factors affecting the working process of the forensic medical expertise employees of samarkand region (doctors, nurses and junior medical staff) is evaluated. temperature during the work process in the green areas and rooms of the employees of the samarkand regional forensic expertise. the questionnaire and microclimate determining meteorometer (samarkand city sanitation, epidemiology, public health department, sanitation and hygiene laboratory) were used. as a monitored group, the employees of the forensic medical expertise of samarkand region (doctors, middle and junior medical staff) and their colleagues working in state institutions were taken. the study was primarily conducted in the workplace on the basis of a questionnaire. the number of forensic medical personnel to be checked was 27 people. formed groups were different in terms of age, sex, work activity and somatic condition. inspection of medical personnel was conducted at the beginning and at the end of the work day. in order to assess the severity of the work of corpse workers and the presence of stress, an accurate load observation of working time was carried out, taking into account two options for the organization of work. in this, the effect of the seasonal conditions on the normal activity was studied, in particular: medical and diagnostic examinations, medical documentation, walking in the room, taking analysis for the laboratory while standing, the effect of the microclimate on the organism during production was studied, and 27 chronometric questionnaires were analyzed. atmospheric temperature was determined using a meteorometer. to determine the reliability of the difference between the average values, the values of the norms of the temperature in the departments of the treatment and prevention institutions were used and a correlation analysis was conducted. research results and their discussion analysis of the results of statistical research allowed to determine that in the group of medical experts of the institutions, the effect of temperature on mental work ability decreases, fatigue occurs in the peripheral part of the body, which

during the day. results according to the results of the study, it was found that at the end of the working day, low stability of attention due to changes in the temperature of the doctors working with dead bodies at their workplaces, depending on the season, is manifested at a much higher level compared to the time spent on the test by senior and junior medical workers (respectively 20.8±2.8 and 16.2±1.15) (р<0.05). forensic workers compared to other workers had significantly lower numbers, that is, 18.9±2.39 and 16.6±2.33 at the beginning of the day, respectively, and 21.7±2.17 and 20.2±2.11 at the end of the day, respectively. the temperature in the rooms differed significantly. by the end of the working day, the decrease in labor activity in the middle group of 3 compared medical workers was determined by the example of a simple calculation operation. when the survey was conducted, the indicator of the work volume of the groups among forensic medical workers was normal at the beginning of the day, and at the end it was significantly worse (respectively 23.3 ± 3.7 and 251.7 ± 1.8). functional status and hearing also differed significantly. it was worse in the group of medical workers, which is confirmed by a significant decrease in pulse rate from 87.3 ± 5.8 to 6.8 ± 0.3 by the end of the working day when the meteorological analysis was carried out from five points of each room (p<0.05). at the end of the working day, the cases of coldness for the body were clearly manifested in the room due to severe fatigue and severe cold in the winter. this was clearly observed when compared to their paramedic counterparts, but clearly identified in the reliable meteorometer. a significant decrease in dynamometry during the working day, in our opinion, proves the obvious fatigue of mortuary workers as a result of working with outdated, non-ergonomic equipment, which requires high physiological costs. in the subjective assessment of the state of health by forensic medical personnel using the questionnaire method, among the complaints reported by medical personnel regarding their health, neurotic disorders, large differences in air temperature in the seasons, pathologies of the digestive system, circulatory system, musculoskeletal system and connective tissue, sensory organs. it was found that the complaints indicating the existence prevailed. however, the proportion of medical staff who subjectively recorded these complaints was higher in the sub-group of medical staff than in the junior medical staff group. among the doctors of this field, the effect of temperature on the body was especially pronounced in the group of medical workers working with corpses and preparations (77.8% and 88.1% and 79.4%, respectively). the number of people whose health was https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 07-2024 31 american

forensic medical workers was 17.6%, and among junior medical workers it was 20.0%. conclusion prophylactic measures should be developed for the influence of microclimatic factors on temperature in the work process of the employees of the forensic medical expertise of samarkand region. a comparative analysis of the workload parameters of doctors and senior medical staff and junior medical staff, their functional status in the dynamics of workload showed that the work of senior medical staff is less dangerous than the work of middle and junior medical staff. introduction of a modern heating

primary damage to the myocardium, characterized by inflammation, tumor, specific cardiomegaly not related to ischemia, worsening heart failure and arrhythmia. it is considered an idiopathic (unknown origin) disease of the myocardium, which is based on the development of dystrophic and sclerotic changes in cardiomyocytes. the following types of primary cardiomyopathy are distinguished: dilated, hypertrophic, restrictive and arrhythmogenic [32,62]. hypertrophic cardiomyopathy is manifested by diffuse hypertrophy of one or all parts of the heart, narrowing of the ventricles. hypertrophic cardiomyopathy is actually an autosomal dominant disease and occurs more often in men of all ages. in hypertrophic cardiomyopathy, the ventricular wall continues with symmetric or asymmetric hypertrophy of the myocardium. morphologically, in hypertrophic cardiomyopathy, fibrotic foci are found on the basis of incorrect location of myocardial muscle fibers, research article characteristics

heart failure [56,59,104]. the purpose of the research: to clarify the specific macroand microscopic changes of the heart in hypertrophic cardiomyopathy; methods we reviewed 5,642 reports from the rpam autopsy department during 2011-2020, and a total of 64 cmps were identified during this period, accounting for 1.13% of all autopsies and 4.7% of cardiovascular diseases. 15 of the 64 identified cases were found to be hypertrophic cardiomyopathy. after macroscopic examination of the heart, 1.5x1.5x0.5 cm pieces taken from the walls of both ventricles and both compartments were frozen in a 10% solution of formalin in phosphate buffer for 48 hours, then washed in running water for 3-4 hours and placed in a series of alcohol batteries of increasing concentration (80˚, 90˚, 96˚, 96˚, 100˚) and dehydrated in chloroform, paraffin with added wax was poured, and bricks were prepared. histological sections 5-6 μm thick were taken from paraffin blocks and stained with hematoxylin-eosin and van gieson stain to identify connective tissue fibers. histological preparations were studied in 10, 20, 40 lenses of a light microscope, and pictures were taken from the necessary areas. results it was found that the macroscopic appearance of the heart in hypertrophic cardiomyopathy consists of the following specific changes. the main hypertrophy-like changes in the appearance of the heart are observed in the left ventricle, where the wall of the left ventricle is thickened by an average of 35-45 mm, all the walls of the left ventricle are thickened to different degrees, the greatest thickening is in the interventricular wall. as a result, it was determined that the condition of obstruction appeared around the blood outlet of the left ventricle of the heart. in 11 of all 15 studied cases, the above-mentioned morphological changes and the development of an asymmetric form of hypertrophic kmp were found. in the rest, it was found that the heart was symmetrical, that is, all areas of the left ventricle were hypertrophied to the same extent. as a characteristic sign of asymmetric hypertrophic kmp, it was observed that the wall of the left ventricle was mainly thickened in the back and the interventricular space, and the difference in wall thickness was 1.2 cm on average. only in some cases (2 cases) was it found that the right ventricle of the heart was hypertrophied, the orifice of the pulmonary artery narrowed, and hypertension of the pulmonary artery developed in hypertrophic kmp. in hypertrophic cardiomyopathy, the ventricular and ventricular spaces have changed to different degrees, in most cases, the left ventricle is dilated and expanded, there are specific structural changes in the mitral valve layers, i.e., they are stretched and

science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 70-78 oclc – 1121105677 publisher: oscar publishing services servi elongated, and their area is increased. in 25% to 65% of cases, thickening of the endocardium is detected, especially in the upper part of the ventricular septal wall, in areas close to the aortic valve. microscopic examination showed that the myocardium of almost all patients had a strong hypertrophy of cardiomyocytes. in this case, as specific microscopic changes, it is observed that the muscle fibers are arranged randomly, that is, in the direction of different vessels. it is determined that most of the myocardial muscle fibers are located in a circle (fig. 1), characteristic tufts of different thickness have appeared, and tumor foci have appeared in their cores. fibrous tissue is densely located between the muscle bundles consisting of cardiomyocytes, and the fibrous bundles are noticeably thick in one place, and relatively thin dark hematoxylinous bundles appear in other areas. cardiomyocytes are hypertrophied due to the thickening of both myofibrils and sarcoplasm, and their nuclei are relatively small and irregular. in other areas of the myocardium, it is determined that part of the muscle fibers are located longitudinally, and the other part is located transversely. it is observed that the myofibrils of the cardiomyocytes of the longitudinally located muscle fibers are thickened to different degrees, the transverse extension lines are lost, and the nuclei are pushed aside. it is determined that transversely located muscle fibers have different thicknesses, some of them are sharply thickened, their borders are unclear, and they merge with each other. fibrous tissue and malformed blood vessels are found at the junction of muscle fibers in different directions (fig. 2). it is determined that the fibers in the fibrous tissue are irregularly arranged, of different thicknesses, and blood vessels similar to random cracks have appeared between them. in asymmetric forms of hypertrophic kmp, the following changes were detected when microscopic examination of the upper part of the wall of the interventricular space of the heart, that is, the part adjacent to the mitral valve. in this area as well, it is determined that the myocardial muscle fibers are chaotically located, as we can see in the picture, thick muscle bundles are visible in cross-section, their sarcoplasm is swollen, and myofibrils are thinned and sparsely located. https://doi.org/10.37547/ajbspi/volume03issue03-01

located longitudinally and form the outer part of the wall of the interventricular space, and myofibrils of cardiomyocytes are relatively dense and darkly stained, but their histotopography is disturbed due to thickening. between the muscle bundles located in the two indicated directions, it is determined that each muscle fiber is separated from each other, dense fibrous tissue has appeared between them (fig. 3). fibrous tissue differs from muscle fibers in terms of its coloring and composition, it is determined that its fibers are densely and irregularly arranged, and its cells are relatively numerous and disorderly. in hypertrophic kmp, it is determined that there are specific morphological changes in the intramural coronary arteries of the heart myocardium. in this case,

science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 70-78 oclc – 1121105677 publisher: oscar publishing services servi it is observed that the walls of almost all intramural coronary arteries are sclerotized and thickened. the larger the diameter of the artery, the more connective tissue grows around it and is found to be sclerosed (figure 4). it is determined that the intima of these arteries is uneven, the cells in it are hypertrophied and hyperchromic, and the basal membrane is also thickened. smooth muscle cells are found to undergo both hyperplasia and hypertrophy, and some muscle cells are surrounded by fibrous tissue. due to the abundance of fibrous structures in the surrounding connective tissue, it is determined that it is densely wrapped around the vessel in the form of a ring, as a result, the artery cavity is compressed and narrowed. it is determined that the walls of relatively small arteries and arterioles are thickened due to the growth of the connective tissue, which has spread and penetrated into the surrounding muscle tissue. as another characteristic change of hypertrophic kmp, thickening of the endocardium of the left ventricle, growth of connective tissue, and sclerosing were found in most cases. it is observed that the endocardium of the endocardium is atrophied and desquamated in some places, migrated, and in other areas it is proliferated, increased and thickened. the basement membrane beneath the endothelium is found to have almost disappeared, disintegrated, and merged with the surrounding newly formed connective tissue. it is observed that the endocardium is thickened in the section (fig. 5), and even grows towards the myocardium adjacent to it. it is determined that the connective tissue fibers and cells in the endocardium have undergone dystrophy and dysregeneration and have changed morphologically. fibrous structures are determined to be shriveled and fragmented due to strong swelling in some places, relatively pale in color, in other places they are dense, homogenized, and destroyed like fibroelastosis and hyalinosis. it is found that the cellular composition of the endocardial tissue is thinned, their nuclei are deformed and hyperchromic. myocardial muscle fibers adjacent to the endocardium are fragmented, separated into parts, and most of them are destroyed. the destruction of muscle fibers is manifested by the loss of the nucleus, the loss of cross-promoting lines in myofibrils, their homogenization and myolysis. https://doi.org/10.37547/ajbspi/volume03issue03-01

are found in the myocardium of the heart in individual cases. it is observed that the rough fibrous connective tissue completely covers the endocardial layer and has grown into the myocardium (fig. 6). fibrous tissue contains a significant number of fibrous structures with a coarse structure, and the intercellular substance has a finegrained coarse eosinophilic structure. fibrous structures are chaotically arranged, and in some areas dark colored fibrous concretions with a dense and coarse texture are found. it is observed that connective tissue cells are significantly less than fibrous structures, they are randomly located, the cytoplasm of most of them is vacuolated and https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

and separate islands appear, and the cardiomyocytes in these islands are destroyed and located in a disorderly manner. it should be noted that in most cases of hypertrophic kmp, the functional state of the mitral and aortic valves is impaired. the morphological basis of these functional disorders is definitely the pathomorphological changes developed in the myocardium and, in addition, the development of sclerosis and fibromatosis in both the myocardium and the endocardium. the reason is that due to the development of fibromatosis in the endocardium, the sclerosis process spreads to the layers of the valves, causing it to be structurally damaged. in this case, the microscopic examinations showed that the myocardial tissue adjacent to the layers of the heart valves is hypertrophied and thickened, and the connective tissue that is part of the valves adjacent to it is fibrosed and thickened. it is determined that the fibrous structures in the fibrous tissue have multiplied and are scattered in this place, on the one hand, they have spread to the myocardium, and on the other hand, they have deformed the surface of the plate. it is determined that the connective tissue cells in the fibrous tissue of the cap layer are relatively few, and those that are present are vacuolated, hydropic dystrophy, and are randomly located. conclusion in most cases of hypertrophic kmp, an asymmetric shape is developed, the wall of the left ventricle is mostly thickened in different degrees, the left ventricle is dilated in most cases, specific structural changes in the layers of the mitral valve, i.e., they are stretched and elongated, and their area is increased. in 25% to 65% of cases, thickening of the endocardium is detected, especially in the upper part of the ventricular septal wall, in areas close to the aortic valve. microscopically, this hypertrophic kmp is a typical condition, that is, the muscle fibers are located in a chaotic and chaotic manner, the connective tissue grows between the muscle bundles, the fibrous tissue develops, the fibrous tissue often occupies the subendocardial area and the endocardium thickens, the fibrous tissue spreads to the valvular layers, as a result, it leads to a functional violation of the valve. proved. references 1. gudkova a. ya. cardiomyopathy. natsionalnoe rukovodstvo "cardiology" (short version) pod ed. acad. ran e.v.

method, and the skin-vascular reaction (csr) to histamine was studied, which¬was evaluated by three indicators: intensity, duration index¬(id), and character. the intensity was expressed by the¬erythema diameter that occurred at the injection site of 0.01% histamine solution 5-minutes after scarification. the duration index was calculated as a percentage of the erythema diameter at 5 and 15 minutes. depending on the id of the cutaneousvascular¬reaction, it was subdivided as follows. at id, up to 40% of dac¬was changed to normal, from 14 to 80% — to slow, and more than 80% — to stagnant. in addition, the level of glycosaminoglycans in the blood serum was determined by the turbometric method. a total of 50 patients aged 18 to 35 years with polyp¬posal sinusitis were examined. in 22 patients, an edematous polyp was found in the general nasal passage¬, which occupied almost the entire half of the nasal cavity and often¬descended into the nasal pharynx. at the same time, there was no nasal breathing on the same side. in 28 patients, the polyps were significantly smaller, located in the nasal cavity, causing moderate difficulty in breathing. in 45 children, the polypous process was in the maxillary sinus, in 4-in the maxillary sinus and sinus of¬the ethmoid bone, in one child the polyps came from the sphenoid sinus (polypous form of sphenoiditis). some patients reported head¬pain, general malaise, subfebrility, etc. a carefully collected allergic¬history revealed that 5 patients had exudative diathesis and 4 had drug intolerance. bronchopulmonary pathology (recurrent bronchitis, pneumonia, cartagener's syndrome) was observed in 8 patients simultaneously with sinus involvement¬хит, пневмония, синдром картагенера. of the patients we examined, 13 patients had previously undergone polypotomy. however, most of them мес — 1 год отме¬had recurrent nasal polyposis after 3 months-1 year. to clarify the diagnosis, we used contrast xray¬imaging, which allowed us to determine the location of the initial polyp growth and¬determine the scope of intervention. in 49 patients, a maxillary sinus was performed,4 of them simultaneously opened the cells of the sinus of the ethmoid bone and 1-the sphenoid sinus. along with surgical intervention, as a rule, general strengthening and desensitizing treatment was performed¬. children were examined in dynamics: at admission to the clinic and 1-2 years after surgery. of the 50 operated patients, 44 had positive results, and 6 had a-recurrence of the disease. the results of the determination of serum immunoglobulins in the observed patientsare shown in table 1. table 1 the content of immunoglobulins in blood serum in children with polypous sinusitis

that hypoimmunoglobulinemia is characteristic of¬most patients. the level of ig m below normal was found in 48 out of 50 patients¬, a igand ig a and ig m — in 26. high levels of ig a were observed only in 8 a children, and ig g — in 6 children. the results of the csr test for histamine and the content of one of the components of the properdine system (magnesium) in the blood serum are presented

pronounced bimodality: in 23 out of 50 people, the magnesium level was below 0.75 mmol/l, in 7 — above 1.05 mmol/l. in children of the control group, the distribution of magnesium content in the blood

difference in intensity is significant (p<0.01). thus, the characteristic signs of allergization (low¬content of magnesium in the blood serum and increased concentration¬of histamine in the tissues against the background of its delayed inactivation) were detected in almost half of the sick children (the frequency of detection¬of these disorders was 0.46). this pattern was especially clearly observed in individuals (75%) with аллергизацииa history of allergy symptoms, which may¬be to some extent associated with a low concentration-цией ig of ig g.. recurrent polyposis was characterized by a decrease in the level of serum ig a and ig g (with a frequency of 0.71) and¬a violation of the exchange of glycosaminoglycanemia. low production of class a and g immunoglobulins was noticed g(in 8 out of 10 children with persistent relapsing process). similar data are provided by v. i. fedorich and n. v. minin (1985), who studied the content of serumimmunoglobulins in adults with polypous sinusitis. in the long-term period (1-2 years after rehabilitation)¬, the immunological status of these children underwent the following changes:¬the content of ig m decreased, the levels of ig g and magnesium in¬the blood serum increased, and histamine metabolism significantly normalized. the latter was reflected in a decrease in the intensity and duration index-of skin-vascular reactions. during these periods, examinations for¬slow csr for histamine were detected in those who underwent surgery with almost the same frequency as in the control group (in 42% and 40%, respectively). particular importance was attached to the nature of the dynamics¬of the analyzed indicators. the dynamics characterized by the aggravation of violations detected during the initial examination was considered negative¬, and the normalization or tendency to it of the corresponding indicators was considered positive. positive dynamics in all indicators was noted in 40% of children, which, undoubtedly, can serve as an objective criterion for the effectiveness of the rehabilitation performed. special attention should be paid to patients with negative dynamics¬of all indicators of humoral immunity. it should be emphasized that the results of their initial examination indicated a high¬degree of intensity of immunological processes. https://doi.org/10.37547/ajbspi/volume03issue03-01

the examination of patient f., 18 years old. when the patient was admitted, the serum magnesium content was 1.05 mmol / l, a pronounced csr for histamine was determined (the intensity of 17 mm id is 4.7), a low concentration of immunoglobulins (iga-81.4 iu / ml, igg-95.2 iu / ml). 7 months after the rehabilitation, there was a sharp decrease in the level of magnesium (up to 0.55 mmol/l), iga (up to 20.3 iu/ml), igg (up to 34.1 iu/ml) and complete areactivity according to the data of skinvascular reactions to histamine (intensity is 0, erythema is absent). in this case, we can probably speak of¬an immunological breakdown caused by an intervention performed against the background of a significant strain of immunological protection. the determination of non-specific indicators of¬humoral immunity confirmed the concept of a number of researchers that the development of a chronic infectious and allergic process in the paranasal sinuses is associated with general autoimmune disorders¬and helps to clarify the relationship between the features of the immune¬response and the clinical manifestations of recurrent¬polyposis in children. the development of pronounced hyporeactivity in a number of patients may serve as a basis for measures¬aimed at stimulating general immunological resistance.¬a comprehensive dynamic study of the listed¬indicators of human immunity deserves attention as an objective criterion¬for the effectiveness of treatment of persons with polypous forms of sinusitis. it seems promising to further study the relationship between the increased concentration of serum gags, on the one hand, and excessive formation of polypous tissue in children, on the other, as well as between the low concentration of these structural components of connective tissue and the recurrent nature of the pathological process. you are a water user 1. пациентов, страдающих полипозной формой синуитаthe¬content of serum immunoglobulins of classes a and g is reduced in patients

the study: of these, 100 are healthy and 200 are labourers with periodont disease. we divide these working employees into 2 groups. group 1 is healthy coworkers and forms a control group. group 2 is the working co-workers with periodont disease. we divide 200 working employees with parodont disease into 2 more groups. we will study them for 6 months through a medical card, which is maintained by the nurse of the enterprise, as well as through the data of the polyclinic. diagram 1 grouping by age https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

which is maintained by the nurse of the enterprise, changes in the dental system. with an increase in work experience, the number of workers with periodontitis of moderate weight increased. the most common disease of the oral mucosa is keratosis, which is observed 6-10 times more often in the working group than in the control group. it is observed among employees who work with chemical dyes. we can see a decrease in electrical excitation in the central teeth. similar results have been noted for molars and molars (diagram 1). when control groups were examined, the same results were recorded on the shovel tooth, molar and food teeth, regardless of the anatomical shape of the teeth. it is also worth noting that as seniority increases, the emergence, development and exacerbation of periodontal disease among employees is increasing. diagram 2 by age men women 0 5 10 15 20 25 30 1 2 3 4 5 by age men women https://doi.org/10.37547/ajbspi/volume03issue03-01

to periodontal disease, workers in paint shops also suffered from leukoplakia, stomatitis and various inflammations in the oral cavity (diagram 2). we learned about the health information of employees working in chemical enterprises from a medical card kept by a nurse working in factories. as a result of our observations, it became known that in a certain percentage of employees there, periodontal disease, its development, complications arose depending on seniority. also in the oral cavity, along with periodontal disease, there was leukoplakia on the tongue, as well as stomatitis, inflammation of the gums, swelling, fragility of the teeth. conclusion 1.the information obtained expands the information about the anatomical and histological structure of the tooth and their changes with age. 2. the data obtained from mothers who work with chemical dyes about the salinity of the teeth of offspring will help to understand the changes that occur in the tooth when working with chemical dyes in the human body. references 1. usmanov r.dj., gulmanov i.d., nortaev a.b. development and prevalence of periodontal diseases in workers working with chemical paints // 100 years of the tashkent medical

turns into a coherently dispersed system with a certain porosity value. at the same time, the tableting process is influenced by the technological properties of the substance, such as fractional composition, bulk density, flowability, angle of repose, compaction coefficient, compressibility, force of ejection of tablets from the matrix and static humidity. to obtain tablets, meeting the requirements of quality standards is the study of the technological properties of the pharmacologically active substance [1,2]. the correct choice of excipients during the tableting process gives the tablet mass the necessary technological properties that ensure dosing accuracy, mechanical strength, disintegration and stability of the tablets during storage [3]. purpose of the study determination of the composition and technological properties of a substance based on echinacea purpurea juice, for “immunacea bio” tablets with immunomodulatory effects . materials and methods the fractional composition or percentage distribution of powder particles by size has a certain influence on the degree of its flowability, and therefore on the rhythmic operation of tablet machines, the stability of the mass of the resulting tablets, the accuracy of the dosage of the medicinal substance, as well as the quality characteristics of the tablets. the fractional composition of the substance based on the juice of echinacea purpurea was determined using the sieve method. the dried juice of echinacea purpurea is a brownish-green powder with a peculiar odor. bulk density is the mass per unit volume of freely poured powder and depends on the density and humidity of the substance, the shape and size of the particles, and their placement. based on the bulk density value, the nature of the excipients used and the volume of the matrix channel of tablet machines are predicted, because dosing of tablet masses in them is carried out by volume. determination of bulk density was carried out using a volumetric meter and a stainless steel vessel with a volume of 100 ml . flowability is the ability of a powdered material to crumble under its own gravity and ensure uniform filling of the matrix channel. material that has poor fluidity in the funnel sticks to its walls, which disrupts the rhythm of its flow into the matrix. this causes the target weight and density of the tablets to fluctuate. the flowability of the mass was determined using a vp 12a device. an indirect characteristic of flowability the angle of repose the angle α between the generatrix of the cone of bulk material and the horizontal plane is determined from the equation tg (α) = cone height/(0.5 × base diameter). flowability was also determined by the flow rate through the nozzle using a vp 12a device. the interactions between particles that affect the bulk properties of a powder also affect the flow of the https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

particles and the values of bulk density and density after shrinkage will be close. for less flowable materials, large differences between bulk density and shrinkage density are observed. therefore, fluidity can be assessed by the powder compaction coefficient. compressibility – ability of powder particles to cohesion under pressure, i.e. the ability of particles, under the influence of forces of an electromagnetic nature and mechanical engagement, to mutual attraction and adhesion with the formation of a stable, strong compact. when determining the compressibility of a powder ( granulate ), a sample weighing 0.3 or 0.5 g is pressed into a matrix using punches with a diameter of 9 mm and 11 mm on a hydraulic press at a pressure of 120 mpa. to push a pressed tablet out of the matrix, force is required to overcome friction and adhesion between the side surface of the tablet and the matrix wall. antifriction substances were selected taking into account the magnitude of the buoyancy force. when determining the ejection force, a sample of powder weighing 0.3 was pressed into a matrix with a diameter of 9 mm on a hydraulic press at a pressure of 120 mpa. the pressed tablet is ejected using the lower punch. at the same time, the buoyancy force was recorded on the pressure gauge of the press[4,5]. the results of studying the physicochemical and technological properties of dried

material . to improve the technological properties of the original drug substance and obtain tablets of appropriate quality with maximum therapeutic effect and minimal side effects, it is necessary to conduct appropriate research on the selection of the rational composition and optimal technology of the tablets being developed. based on the selected optimal combination of factor levels, the following composition for immunacea bio tablets was proposed[6] . compound: echinacea purple herb juice dried 80 mg microcrystalline cellulose 15 9.0 mg magnesium stearate 2.5 mg aerosil 5.0 mg _

(3, 14, 15, 20). these diseases are fraught with various complications. at the same time, there is an increase in the frequency of severe chronic forms of lung diseases in children, leading to disability already in childhood (21, 17, 31, 49, 69, 73, 95). the morphology of the functional activity of the structures of the airways and lungs under normal conditions and in a number of pathological conditions has been studied in great detail. assessing the changes that develop in the bronchopulmonary system during a particular inflammatory pathological process serves as the basis for understanding the patterns of compensatory and adaptive reactions in the respiratory organs. respiratory diseases are an urgent health problem due to their widespread prevalence, occupying one of the leading places in the structure of morbidity and mortality of the population. in recent years, there has been an increase in the incidence of chronic and recurrent lung diseases among children and adolescents (13, 22, 23, 24, 25, 26). despite the progress achieved in diagnosis and treatment, diseases of the respiratory system still occupy one of the first places in the structure of morbidity among children and adolescents. along with the high level of morbidity, there is an increase in the general population in the number of recurrent and chronic forms of respiratory diseases, often leading to disability. broncho-obstructive syndrome is more often observed in young children (20.1%). moreover, in more than half of children (57.5%), episodes of obstruction recur (26, 27, 28, 29, 30, 31) some clinical studies show that computer aided diagnosis (cad) can improve the diagnostic performance of junior radiologists. chest x-ray is one of the most accessible radiological methods for screening and diagnosing various lung diseases. in many modern hospitals, huge numbers of x-ray images along with radiology reports are accumulated and stored in picture archiving and communication systems (pacs). however, it remains an unresolved question how such a large database containing valuable imaging data (i.e., freely labeled) can be used to support datahttps://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 33 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 31-40 oclc – 1121105677 publisher: oscar publishing services servi intensive deep learning paradigms to create truly largescale and highly accurate computer-aided diagnostic systems (cad). structural changes in the respiratory organs detected during the analysis of biopsy samples of the bronchial mucosa, in comparison with the study of bronchial washings and induced sputum, can serve as the basis for determining tissue, cellular and molecular predictors of severe bronchial asthma, as well as differential criteria between bronchial asthma and chronic obstructive disease lungs (32, 33, 34). chest diseases and pulmonary abnormalities are the leading causes of death according to global statistics for 2017 (15, 35). clinical methods for evaluating chest diseases include chest x-ray (cxr), computed tomography (ct), and magnetic resonance imaging (mri). chest x-ray, a painless test, remains one of the most commonly used radiological methods for screening and diagnosing chest diseases (10, 16, 25). a single x-ray may reveal abnormalities such as atelectasis, cardiomegaly, effusion, pleural thickening, and pneumonia. however, the diagnosis of chest diseases using radiography largely depends on the skill of the radiologist, and achieving highly accurate diagnostic results remains a significant challenge. chest x-ray (cxr) is an inexpensive but effective medical imaging technology. however, a shortage of qualified radiologists may significantly limit the use of this method. to improve the efficiency and accuracy of diagnosing abnormalities in chest x-rays, new technologies such as deep learning should be used. deep learning algorithms based on convolutional neural networks (cnns) have made significant progress. the success of cnn in image classification has prompted researchers to explore its usefulness as a diagnostic tool for identifying and characterizing lung diseases. to achieve this goal, we leverage and extend the efficientnet family of deep artificial neural networks, known for their high accuracy and small size in other applications. a collection of three datasets is used to train the proposed approach. the results show that the proposed approach produced a high-quality model with an overall auc of 0.871 and an overall sensitivity of 79.4%, while having 5 to 30 times fewer parameters than other architectures (36, 37). when comparing high-resolution computed tomography studies of the lungs with histological lung remodeling in explants with usual interstitial pneumonia, hrct findings were found to be typical of uip and hrct of the lungs correlated best with bronchiolectasis histologically. the nsip pattern is common and is associated with ct detection of hgo. histologic features were compared with three hrct findings: diagnostic appearance (uip, probable uip, or incompatible with uip), degree of honeycombing, and degree of ground-glass opacification (38). acute fibrinous and organizing pneumonia is a histologic pattern associated with the clinical presentation of acute lung injury that differs from the

science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 31-40 oclc – 1121105677 publisher: oscar publishing services servi classic histologic patterns of dad, boop, or ep. similar to these patterns of acute lung injury, the afop pattern can occur in idiopathic settings or with a number of clinical associations. the overall mortality rate is similar to dad and may therefore represent a histological variant; however, afop appears to have two distinct patterns of disease progression and outcome. the need for mechanical ventilation was the only parameter correlated with prognosis. none of the patients with subacute clinical course required mechanical ventilation (39). medical imaging methods allow us to identify and record abnormalities in the human body. these techniques are critical for the assessment, diagnosis and treatment of lung diseases. currently, there are a variety of research methods: ultrasound of the respiratory organs, densitometry, digital radiography, fluoroscopy of the lungs, ct scan of the lungs, mct and other research methods. radiation diagnostics is the main method of radiation examination in children of the first age, which allows identifying functional and clinical changes in the lungs (40, 41, 42). densitometry is a key method in multislice computed tomography (msct), which helps to detail pathological changes in the organs of the chest cavity. chronic progressive inflammatory process of the airways, especially respiratory bronchioles and pulmonary parenchyma, leads to obstructive disorders of the ventilation function of the lungs, mucociliary dysfunction, accumulation of neutrophils in the respiratory tract mucosa and bronchial remodeling (43, 44, 45). in children with pneumonia, chest x-ray (cxr) is usually the first diagnostic test. if complications such as abscesses or empyema occur, repeat x-rays or ct scans are often required, increasing radiation exposure. this retrospective study assessed the potential of radiationfree chest mri to detect complications initially and later compared with chest radiography and pulmonary ultrasound (lpus). cxr and usl are usually sufficient, but in cases where usl is not possible or the combination of cxr+usl is ineffective, mri should be preferred. however, the use of contrast agents is not necessary (46, 50). usl has high internal consistency (irr) for detecting consolidation. compared with ct, ultrasound and chest x-ray (cxr) show similar sensitivity, but cxr has greater specificity in diagnosing pneumonia (46, 17, 49, 50) chest x-ray (cxr) is the mainstay of diagnosis for community-acquired pneumonia (cap). some authors have recently suggested that chest ultrasound (cus) can effectively complement or even reliably replace xray examination in the diagnosis and surveillance of cap. we examined the clinical utility of usg in a large sample of patients with cap to challenge the hypothesis that it can replace radiography. to improve understanding of the clinical, radiological and pathological features of acute fibrinous and organizing pneumonia (afop), the clinical data of 5

science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 31-40 oclc – 1121105677 publisher: oscar publishing services servi patients with afop were retrospectively reviewed. afop was diagnosed using percutaneous lung biopsy guided by computed tomography (ct) of the chest. the predominant findings on chest hrct were bilateral infiltrates with a diffuse and pathotype distribution. a pathological examination revealed slightly dilated alveolar septa, lymphocytic and plasmacytic infiltration, as well as the presence of intra-alveolar fibrin in the form of fibrin “balls” (organizations) inside the alveolar spaces. no neutrophilic, eosinophilic infiltration, or hyaline membrane formation were observed, which was in contrast to other well-known histologic features of acute lung injury such as diffuse alveolar injury, cryptogenic organizing pneumonia, and eosinophilic pneumonia. all patients received corticosteroids and showed significant clinical and radiological improvement. thus, acute fibrinous and organizing pneumonia has no specific features, and its diagnosis depends on pathological examination. however, whether this is a unique interstitial disease requires further clinical investigation (47). conclusions thus, literature data show that in order to improve and timely diagnosis and prevention of inflammatory diseases of the bronchopulmonary system, it is advisable to carry out radiological diagnostic methods. morphological studies of pleural fluid can affect the course of diagnosis and treatment of children with pneumonia. ultrasound examination revealed pulmonary consolidation in more than 70% of patients with radiographic community-acquired pneumonia, but gave false negative results in 26.5% of cases. longitudinal results from some authors support the role of usg in the surveillance of detectable lesions. in summary, usg should be considered as an additional tool for monitoring pneumonia rather than as a primary imaging modality. digital radiography (chexgat) is considered more sensitive, reliable, and highly specific. multislice computed tomography gives less radiation exposure to the child’s body, and in addition, in relation to digital radiography, it is more sensitive, specific and reliable. references 1. линденбратен л.д., королюк и.п. медицины,2000,,с.-165-230, труфанов г.е.

mineral acid. the use of the term "liquid glass" to describe silicate suspension products has led to considerable confusion due to the lack of a clear definition of liquid glass. historically, the term "liquid glass" was used to describe silicate solutions whose solubility exceeded the solubility limit of anhydrous silicates, and was usually prepared by dissolving silicon with an alkali metal carbonate and then dissolving it in water. this variety has been widely used in heavy industries such as mining, metalworking and ceramics. with the development of hydrated silicates, the term "liquid glass" became increasingly research article theoretical basis for the manufacture of sodium silicate pentahydrate submission date: april 14, 2024, accepted date: april 19, 2024, published date: april

increased, the term became less specific. as a result of uncertainty as to what grade of silicate is required for a particular application, the term "water glass" is not used and a more precise specification is usually required. liquid glass, a mixture of silica and alkali, has been used since the early 19th century. application, drying time, adhesion and tensile strength make the specification of each silicate model very important for each of the applications mentioned above. nowadays, sodium silicate is very important due to its use in various fields. the main consumers of sodium silicate are synthetic detergents and the cardboard industry. if we trace the history of these industries, we will see that the growth of the detergent industry largely depends on the growth and production of washing machines. the increased demand for automatic washing machines has increased the demand for sodium silicate, which is used as a binder, buffer and anti-corrosion agent in the production of household washing machines. sodium silicate has been found to be very useful in the production of detergents used in dishwashers. using sodium silicate acid recycling technology, corrugated cardboard can be processed into recycled cardboard and boxes. sodium silicate has been found to be useful in the following applications: binder for waste paper recycling, reinforcement and bonding processing, internal sizing and reinforcing additive. without sodium silicate there are no other possible alternatives to the above conditions. this shows that the production of detergents and paperboard depends on sodium silicate. consumer concerns about the environment, coupled with industry pricing pressures, are driving demand for environmentally friendly chemicals. this has led to an increase in the use of liquid sodium silicate as a raw material instead of solid silicate or potassium silicate. main part the goal is to create an industrial database of the characteristics and properties of these types of silicates and their response or effectiveness at various industrial scales. this allows for the intelligent development of new products and processes, and the determination of the amount of silicate required for a particular application with greater accuracy than is currently possible. this can only encourage further research into silicates that will benefit the industry. erosion of the basis of inorganic materials and reactions can only occur at the stage of complete knowledge of the mechanism of these materials. this increases the likelihood that the detected program is not random. typically, soluble silicates are slightly ionized at this ph and their solubility varies little over a wide ph range. higher temperature increases solubility. the solubility of silicates at different ph values varies greatly among different silicon polymers. when the sio2 level exceeds about 70%, silicas are formed, which are readily soluble https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 04-2024 25 american journal of biomedical

services servi in acids or alkalis. unlike silicate, which can be neutralized and still remain the same material. silica gels range from the acidic end of the ph range to alkaliactivated silicas, covering a range of ionized and weakly ionized colloidal materials. the significant increase in silicate solubility compared to modification of sio2 polymers has interesting and often beneficial effects, especially in bonding and surface modification. silicates are known for their ability to crosslink or change from a sol to a gel state with a noticeable change in ph. the ph value of a 1% solution is approximately 11-12; 4% solution about 13-14. the silicate anion is stable over a wide range of alkalinity. in highly concentrated solutions, the alkali can be absorbed by the cation exchange resin to such an extent that the silicate is converted into a soluble cationic form. this is also the mechanism by which silicate becomes silica. the stability of the ion in dilute solution causes the silicate to revert to anionic form and move to a higher ph environment. the solubility of sodium silicate is affected by the ratio of glass and alkali. as the ratio of sio2 to na2o increases, the solubility also increases due to the increased polymerization of the material. quality control is one of the most important processes in sodium silicate pentahydrate technology because product quality changes as system conditions change. sodium silicate pentahydrate is difficult to standardize due to the lack of specific characteristics to determine its quality. this is due to the fact that sodium silicate is very reactive towards other substances. sodium silicate pentahydrate is best used immediately after production. but in fact, it is better to let it sit for a while before using it. therefore, it is necessary to change the quality of sodium silicate pentahydrate to make it more stable. if too much gel forms, one amount may be good and another may be bad. the following properties are standard for determining the quality of sodium silicate pentahydrate: viscosity content of insoluble substances ph value is a characteristic of sodium silicate, since viscosity describes the nature of sodium silicate. high viscosity sodium silicate has more stable quality. the high viscosity of sodium silicate makes the mixing process difficult when used to make soap. typically, viscosity is determined in the pulp and paper machine testing room. conclusion 1. it is recommended to make minimal changes to existing technology. it is proposed to provide mechanical mixing for better mixing of the calcined gypsum and the setting agent. the energy requirement for a mechanical mixing device is slightly higher than for the existing paddle mixing system. but if productivity is controlled by the rate of addition of hardener, the overall increase in energy consumption can be kept within 3-4 percent. additional energy costs are offset by reduced storage time

services servi introduction among the most urgent issues in neonatology today are respiratory disorders in infants. due to the morphofunctional features of their respiratory system, respiratory disorders usually develop in premature infants, ranking second in the structure of morbidity among newborns at 8:8 percent [1]. 56.7 percent of newborn and early child deaths are related to respiratory diseases. of the disorders of the newborn's respiratory system, pneumopathy has a unique place. a non-inflammatory lung lesion is the pathology that affects newborns. etelectasis, edematoushemorrhagic changes, and hyaline membranes are found during the pathological examination of newborns that died from pneumopathy [3,4]. in pneumopathy, the newborn's gestational age typically determines the incidence, prevalence, and degree of lung damage. the propensity to develop the disease increases with shorter gestational ages [2,5,6]. pulmonary destress syndrome, a broad term for the clinical signs and symptoms of pneumopathy, is defined as varying degrees of critical respiratory distress. as soon as the baby is born, breathing becomes shallow and frequent due to this pathology. severe cases have widespread swelling, quickly worsening cyanosis, heart failure, and foamy fluid leaking from the mouth and nose. pneumopathy forms are very difficult to differentiate clinically [3]. study goal: depending on gestational age, identify the type of pathomorphological alterations in the lung tissue and bronchial wall of neonates that perished from pneumopathy. materials and methods of research: the perinatal center of the samarkand region, along with the pathological department of the samarkand regional multidisciplinary hospital, examined the bodies of 74 newborns who died from various forms of pneumopathy. the materials from these corpses are included in this study. there were 42 (56.8%) boys and 32 (43.2%) girls among the 74 newborn bodies accounted for. the following is a breakdown of the body weight of newborns at birth: 6 (8.2%) weighed between 500 and 999 g, 28 (37.8%) weighed between 1000 and 1459 g, 22 (29.7%) weighed between 1500 and 2000 g, 12 (16.2%) weighed between 2000 and 2500 g, 4 (5.4%) weighed between 2500 and 3000 g, and only 2 (2.7%) weighed more than 3500 g. newborns are distributed according to gestational age: 12 (16.2%) were born between 22 and 28 weeks, 21 (28.4%) between 29 and 31 weeks, 32 (43.2%) between 32 and 34 weeks, and 12 (16.2%) between 35 and 37 weeks. upon analyzing newborns based on their apgar score at birth, it was discovered that 24 infants (32 %) had severe asphyxia at birth, 34 (46 %) had moderate asphyxia, and only 16 (21 %) had mild asphyxia. https://doi.org/10.37547/ajbspi/volume03issue03-01

the pathoanatomical and additional histological examination of the lungs of the deceased newborns: hyaline membrane disease in 18 (7.3 percent) of the deceased, edematous-hemorrhagic pneumopathy in 8 (19.5 percent) of the newborns, and combined aspiration-pneumopathic syndrome in 2 (8.9 percent) of the infants. primary pulmonary atelectasis was identified in 46 (47.7 percent) of the infants in the study. the shor method was used to completely remove the organs from the infants' bodies before performing a pathoanatomical examination. chest tissue from all lobules, including the main and lobar bronchi, was removed for histological analysis during the autopsy. the materials were dehydrated in 70, 80, 90, 96, and 100% alcohols and chloroform for 72 hours. they were then fixed in 10% neutral formaldehyde for another 72 hours, rinsed under running water for three to four hours, and then put into blocks by embedding them in paraffin with wax. we used a microtome to cut sections that were 3–5 µm thick. in a thermostat set to 57 o c, paraffin was melted and then removed from the sections using acid. staining of objects in sections of lung tissue and bronchi was done using the van gieson method, which involved staining them with picrofuchsin to identify collagen fibers and hematoxylin-eosin solution to study their histological structure. using the point counting method, a morphometric study of the lung and bronchus mucous membrane was conducted, as per g. g. avtandilov (1984). this technique was used with pinpoint eyepiece inserts under a microscope. ten different fields of view, roughly evenly spaced throughout the section, were examined. the volume fraction of the structural components under study was computed using the data that was gathered. hematoxylin and eosin-stained histological preparations were used for a statistical analysis of the bronchial mucosa tissue. software called statistica 6.1 (statsoft inc. , r usa) was employed to analyze the statistical data. results of the study: the material was divided into the following groups according to the distinct nosological forms of pneumopathy in newborns based on their periods of maturity: 1) primary lung atelectasis by gestation: 22-28 weeks, 29-31 weeks, and 32-37 weeks. 2) hyaline membrane disease based on an infant's prognosis. 3) pneumopathy exhibiting an edematoushemorrhagic pathology, which is also contingent upon the neonatal life stage. using a macroscopical approach, an autopsy on the lungs of infants diagnosed with primary pulmonary atelectasis showed reduced volume, airless, cyanotic, collapsed lungs with pointed, flat edges that did not fill the pleural cavities entirely. the pleura typically had a moderate sheen; subpleurally, there were occasionally multiple pinpoint hemorrhages. the lung tissue was doughy-elastic to the touch, and the parenchyma was dark, bloody, and reddish-blue in color in that area. small foci of light red air parenchyma were seen in some newborns; these were thought to be distelectatic and were mostly https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

recorded. the epithelium of the bronchi was partially exfoliated, their lumens were free, and in some infants the bronchi looked asleep. the proper layer of the bronchial mucosa is built from a delicate network of collagen fibers; smooth muscle cells were detected in the muscle layer. collagen fibers were detected in the submucosa of the bronchi. cartilaginous plates were identified in large bronchi; they had a rounded shape and were connected to each other by collagen fibers. respiratory bronchioles were dilated, immaturity of the pulmonary parenchyma was revealed with the presence of unstraightened alveolar ducts, multiple glandular and tubular formations, lined with cuboidal epithelium, separated by wide layers of loose connective tissue, with a sharp congestion of microcirculation vessels. in isolated cases, fragments near the amniotic fluid, amniothelial scales and meconium bodies were detected in the bronchi. in newborns who died after 6-7 days, the mucous membrane of the bronchi had uneven edges, and some had no cilia. the submucosa of the large bronchi contained fuchsinophilic collagen fibers. the cartilaginous plates in the large bronchi were defined as round in shape and were connected to each other by collagen fibers, forming a fibrocartilaginous sheath. in small and terminal bronchioles, the mucosal epithelium was cubic. the lumens of the respiratory bronchioles contained desquamated epithelial cells and eosinophilic masses. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

in the acinar alveoli and terminal alveolar ducts. the epithelium was flattened, and the alveoli had a round or unevenly oval shape. there were wide interalveolar septa. there were perivascular accumulations of red blood cells, the veins were somewhat dilated and full of blood, and the capillaries appeared deserted. the veins were somewhat full of blood, the lymphatic vessels were dilated, the pulmonary artery lumens were free, and some of the veins had blood clots in their lumens. the following histological picture of the bronchi was found in newborns with a gestational age of 29–32 weeks who died within 24 hours of birth: hyaline cartilaginous plates, a small number of elastic and collagen fibers, a small number of mucous glands, and insufficient expression of smooth muscles. the bronchi exhibited a slit-like lumen and a deformed appearance when atelectasis was present. the interlobar bronchi's mucous membrane folded in medium and large sizes, with large foci of desquamation and columnar epithelial cells lining them. desquamated epithelial cells were found in layers and in groups within the lumens of terminal bronchioles and small bronchi. the morphological characteristics of the newborns in this group's lungs included edematous fluid in numerous alveoli and dilated alveolar ducts, which contain trace amounts of hyaline-like masses. the pulmonary artery branches appeared somewhat clogged, and the lymphatic vessel lumens were dilated. subpleural hemorrhages were seen, and the pleural tissue appeared loose. in children who died 6-9 days after birth, dystelectasis, hemorrhage, and bleeding foci in the alveoli were identified. bronchi of different calibers maintained a free luminescence; attention was drawn to a small amount of dense epithelium and the presence of a large amount of mucus. collagen fibers were found in the submucosa of the large bronchi. cartilaginous plates were identified in the large bronchial structures in round form, connected by collagen fibers, and formed the fibrocartilaginous membranes of the large bronchial structures. in small and terminal bronchioles, the mucous membrane epithelium forms as a cubic one. the alveolar ducts looked large, and the inner walls of many of them were covered with hyalin membranes. in alveoli without hyalin membranes, epithelial cells had homogeneous eosinophilic cytoplasms, with

single-layer, cubic in type. in the wall of the bronchi, compact muscle cells and fibers of the connecting tissue layers have been detected. small amounts of elastic fibers were detected, as well as mucous glands. the cartilage plates of large bronchis consist of a basophile interstitial material and individual chondrocytes. the medium-sized bronchi do not contain cartilage plates. in atelectasis, bronchial areas often had deformed appearances and lumens similar to slits. there was a medium and large folding of the mucous membrane of the interlobal bronchi, surrounded by cylindrical or glass cells with large dequamation foci. the bronchial tree's inner epithelium was significantly desquamated. there was an accumulation of neutrophil leukocytes in the lumen of the alveoli, the presence of alveolar macrophages, and a sharp confluence of microvasculature with edema and focal hemorrhages. the accumulation of myeloid cells was observed in the respiratory bronchioles. in newborns with hyaline membrane diseases who died before 24 hours of life, the lungs were macroscopically significant airless, dark red, and densely matched. the lumens of the bronchi have a star-shaped shape, many of them are cystically dilated, and the bronchioles were identified as being transformed into cystically dilated alveoli, forming bizarre cavities (figure 3). in these

services servi beautiful and attractive teeth, as a sign of social wellbeing and beauty, are becoming increasingly in demand for practical dentistry in all social and age groups of the population. scientific research conducted in this area has shown that people with dental discoloration often experience certain problems with social adaptation and are often subject to some kind of discrimination in society. this leads to the demand for both the whitening procedure itself and the range of constantly improved whitening products and techniques offered in dental clinics. increased sensitivity of hard dental tissues, often observed after whitening, is one of the most common pathological conditions that create discomfort and have a negative impact on the functional state of the mouth. according to some data, hyperesthesia affects from 15 to 68% of the population, and the causes of its occurrence are quite numerous. increased sensitivity also manifests itself in carious and non-carious lesions, various damage to the enamel, in particular the presence of cracks, as well as after preparation of hard dental tissues. as stated earlier, increased sensitivity also occurs after professional teeth whitening. the high demand for this type of dental care also requires a timely increase in the effectiveness of treatment and prevention of dental hyperesthesia]. thus, despite the achievements of dental materials science in the development of new means for the treatment and prevention of dental hypersensitivity (based on important microand macroelements, calcium, fluorides, as well as modern desensitizers) that improve the quality of life of the population, there is still a need for further study and comparative assessment of the clinical effectiveness of modern drugs, and on this basis their optimal individual choice for each clinical situation. materials and methods to determine the causes of discoloration , we interviewed 66 patients aged 30 to 40 years who wanted to improve the color aesthetics of their teeth and change their color using professional chemical whitening. in 35% of respondents, staining of the surface of the crowns of vital teeth is caused by ingestion of foods rich in dyes. thus, almost 60% of respondents regularly drink 2-3 cups of coffee a day, and almost 15% of respondents drink carbonated drinks with dyes. one of the main exogenous factors contributing to the development of dental discoloration is smoking. a change in the natural appearance of tooth crowns was most often found in unsatisfactory hygienic condition of the oral cavity in combination with abundant deposition of smoker’s plaque with subsequent pigmentation of the vestibular and oral surfaces of the hard tissues of the teeth. a relatively large proportion of respondents indicated a low level of effectiveness of previously performed whitening procedures. today, there are many desensitizers from various manufacturers on the domestic market, operating on the basis of one or a combination of several https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue

that cause sealing of the dentinal tubules, fluorides and antibacterial components in various combinations. to achieve this goal, the materials of scientific and medical resources on the subject under consideration were studied and analyzed due to the wide variety of combinations of drugs used to reduce the hypersensitivity of hard dental tissues. and based on the results obtained, drugs were selected to assess the clinical effectiveness of their use. this study involved 66 patients aged 30-40 years, with at least 20-25 natural teeth with a preserved crown and without severe comorbidity, with complaints of hyperesthesia of the teeth after professional whitening. in the first group of patients, the drug was gc " tooth mousse " (japan). the drug is a water-soluble cream containing the recaldent complex , consisting of cpp (casein phosphopeptide ) and acp (amorphous calcium phosphate), which has the ability to bind a large amount of calcium and phosphate ions, keeping them in an amorphous non crystalline state and provides high adhesion of the drug to the hard tissues of the tooth, pellicle, plaque components and soft tissues of the oral cavity, thereby providing a prolonged effect of the drug. paste applications were carried out in a clinical setting in accordance with the manufacturer's instructions for 3 minutes. patients were advised to refrain from eating for 30 minutes. each patient was instructed on the use of this drug at home . the drug was applied 2 times a day with a dry finger or applicator after brushing the teeth for 5 minutes. for better penetration of the drug into the interdental spaces, it was recommended to use floss . during the procedure, it was not recommended to spit and swallow saliva. additional rinsing of the oral cavity was not required. for the next 30 minutes, you should not drink or eat. control examinations of patients were carried out at the beginning of the study (initial examination) and during the period of application of the remineralizing drug after 1 and 2 weeks. the obtained data were entered into a special survey card. gluma was chosen as the basis for the treatment of patients in the second group. desensitizer ( heraues kulzer , germany ) . gluma desensitizer is a product containing hema ( hydroxyethyl ) methacrylate , glutaraldehyde and distilled water. the mechanism of action of this drug is that it coagulates the proteins of the dentinal fluid inside the dentinal tubules, forming transverse partitions that block the movement of dentinal fluid, which reduces the sensitivity of the dentin. due to the presence of hema in the composition, its penetration depth increases to 200 microns (0.2 mm). paste applications were carried out in a clinical setting in accordance with the manufacturer's instructions. to begin, the dentin to be treated was cleaned under local anesthesia and then rinsed with water. the mucosa was protected with a rubber dam. then, a small amount of gluma® desensitizer needed for https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 01-2024 96 american journal of

from the application area. after that, the surface was carefully dried with a jet of air until the liquid film disappeared and the surface stopped shining, then washed with plenty of water. control examinations of patients were carried out at the beginning of the study (initial examination) and during the period of application of the remineralizing drug after 1 and 2 weeks. the results of the study showed that patients in the first group, when treated with water-based remineralizing paste gc toothmousse , had comments about the pleasant taste and smell, as well as the convenience and comfort of using this paste. after using it, the feeling of fresh breath remained for a long time. during the study period, according to control dental examinations, there were no cases of local irritating or allergenic effects of the paste on the oral mucosa. thus, regular use of a remineralizing drug contributed to the fact that in 22 patients (88%) complaints about tooth sensitivity disappeared, and in 3 (12%) the symptoms of this pathology decreased. in patients of the second group, on whom gluma® desensitizer was used , before treatment, all patients were clinically determined to have a noticeable pain reaction to irritants. after treatment, dental hypersensitivity disappeared in 20 (80%) patients, and decreased in only 5 (20%) patients. we also found that with repeated local application of gluma® desensitizer , the therapeutic effect is enhanced. the results of treatment of patients were assessed using basic (questioning, examination) and additional ( thermal diagnostics ) research methods. conclusion thus, our research has shown that the most effective remedy for reducing tooth sensitivity was the waterbased remineralizing paste gc toothmousse .

the theoretical frameworks necessary to understand aging mechanisms involving soft and hard electrophiles. aging, a complex biological process, is influenced by various chemical interactions, including those between electrophiles and cellular components. soft electrophiles, characterized by their high polarizability, and hard electrophiles, known for their low polarizability, interact differently with biomolecules, leading to distinct pathways of cellular damage and repair. by examining these interactions through a theoretical lens, the research aims to elucidate the roles of

electrophiles, which are highly polarizable, and hard electrophiles, which are less polarizable. soft and hard electrophiles interact differently with nucleophilic sites within biomolecules, leading to varied pathways of cellular damage and repair. soft electrophiles, due to their high polarizability, tend to form covalent bonds with soft nucleophiles, such as thiols in proteins and glutathione, causing modifications that can impair cellular functions or trigger protective mechanisms. hard electrophiles, on the other hand, prefer to react with hard nucleophiles, such as oxygen and nitrogen atoms in dna and proteins, often resulting in direct damage to these critical biomolecules. understanding the distinct roles of soft and hard electrophiles in aging necessitates the development of robust theoretical frameworks. these frameworks should account for the nature of electrophilenucleophile interactions, the subsequent biochemical pathways activated by these interactions, and the overall impact on cellular homeostasis and aging. by integrating insights from chemistry, biology, and biophysics, such theoretical models can provide a comprehensive understanding of how electrophilic stress contributes to aging. this study aims to explore the theoretical demands and considerations required to elucidate the mechanisms by which soft and hard electrophiles influence aging. through a detailed examination of electrophilic interactions, cellular responses, and the resulting physiological effects, this research seeks to propose models that can enhance our understanding of aging processes. ultimately, these insights could inform the development of targeted anti-aging strategies, potentially mitigating the detrimental effects of electrophilic stress on cellular functions. in the following sections, we will discuss the nature of electrophilic interactions, review existing models of electrophile-induced aging, and propose new theoretical frameworks that address the complexities of soft and hard electrophile involvement in aging. by advancing our theoretical understanding, we aim to pave the way for innovative approaches to combating age-related cellular deterioration and improving health span. method to develop comprehensive theoretical frameworks for understanding aging mechanisms involving soft and hard electrophiles, this study employed a multidisciplinary approach integrating insights from chemistry, molecular biology, and computational modeling. the method comprised several key steps: literature review, classification of electrophiles, analysis of electrophile-nucleophile interactions, computational modeling, and theoretical framework development. firstly, an extensive literature review was conducted to gather existing knowledge on electrophilic interactions and their roles in aging. this review https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi included primary research articles, review papers, and theoretical studies on electrophilic stress, cellular damage, and repair mechanisms. special attention was given to studies that distinguished between soft and hard electrophiles, as well as their specific impacts on biomolecules. secondly, electrophiles were classified based on their polarizability and reactivity. soft electrophiles, characterized by their high polarizability, were identified alongside hard electrophiles, known for their low polarizability. this classification facilitated a clear differentiation in the types of nucleophilic sites these electrophiles preferentially target, such as thiol groups in proteins for soft electrophiles and oxygen or nitrogen atoms in dna and proteins for hard electrophiles. thirdly, the interactions between electrophiles and nucleophiles were analyzed. this step involved examining the chemical nature of these interactions, including bond formation, covalent modifications, and the resulting biochemical pathways. experimental data from previous studies were used to understand the specific modifications induced by soft and hard electrophiles and their subsequent cellular effects. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query=

dynamics simulations were used to model the reactivity and binding affinity of electrophiles with various biomolecules. these simulations provided detailed insights into the molecular mechanisms underlying electrophile-induced damage and repair processes. fifthly, the theoretical frameworks were developed by integrating the insights gained from literature review, classification, interaction analysis, and computational modeling. these frameworks aimed to explain how soft and hard electrophiles contribute to aging through distinct biochemical pathways. the models accounted for the

critically evaluated and refined based on feedback from experts in the fields of chemistry, biology, and aging research. this iterative process ensured that the frameworks were robust, comprehensive, and reflective of the complex interplay between electrophilic stress and aging. by combining literature review, chemical classification, interaction analysis, computational modeling, and theoretical development, this study aimed to create detailed and accurate frameworks for understanding the role of soft and hard electrophiles in aging. these frameworks are intended to guide future research and inform the development of anti-aging strategies that target specific electrophilic interactions and their detrimental effects on cellular health. results the theoretical frameworks developed in this study elucidate the distinct roles of soft and hard electrophiles in aging mechanisms. key findings include the identification of specific interactions between electrophiles and biomolecules, the biochemical pathways activated in response to electrophilic stress, and the differential impacts on cellular functions. interaction analysis: soft electrophiles, due to their high polarizability, primarily target thiol groups in proteins, leading to the formation of covalent bonds https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi that can alter protein function and trigger cellular defense mechanisms. hard electrophiles, characterized by their low polarizability, preferentially react with oxygen and nitrogen atoms in dna and proteins, causing direct damage such as dna crosslinking and oxidative stress. biochemical pathways: the interaction of soft electrophiles with cellular nucleophiles often results in the activation of antioxidant response pathways, including the upregulation of glutathione synthesis and other protective enzymes. hard electrophiles, in contrast, are more likely to initiate dna repair pathways and induce stress responses such as the activation of the p53 tumor suppressor protein. cellular impact: both types of electrophiles contribute to cellular aging, but through different mechanisms. soft electrophiles can lead to chronic oxidative stress and protein dysfunction, while hard electrophiles can cause genomic instability and impaired cellular replication. the cumulative effects of these interactions contribute to the aging process by compromising cellular integrity and function over time. discussion the findings highlight the complex interplay between electrophilic stress and aging, demonstrating that soft and hard electrophiles induce distinct but complementary pathways of cellular damage and repair. these insights underscore the importance of considering the specific nature of electrophilic interactions when studying aging mechanisms and developing anti-aging interventions. the theoretical frameworks suggest that mitigating the effects of electrophilic stress could be a viable strategy for slowing the aging process. for instance, enhancing the cellular antioxidant capacity might be particularly effective against soft electrophile-induced damage, while strategies aimed at maintaining genomic stability could counteract the effects of hard electrophiles. furthermore, the study's computational models provide a valuable tool for predicting the reactivity of various electrophiles and their potential impacts on cellular functions. these models can be used to screen for new compounds with anti-aging properties or to design interventions that specifically target harmful electrophilic interactions. the differential impact of soft and hard electrophiles on cellular aging also has implications for personalized medicine. individual variations in the exposure to electrophiles, as well as differences in genetic susceptibility to electrophilic stress, could inform tailored approaches to prevent or mitigate age-related decline. conclusion this study provides a comprehensive theoretical framework for understanding the roles of soft and hard electrophiles in aging

of great service in finding medicinal plants and extracting alkaloids from them. the effect of medicinal plants on the body depends on the amount of chemical compounds in its composition. these compounds accumulate in different amounts in different parts of the plant. medicinal substances are collected in the shoots, leaves or fruits of some plants, in the roots or bark of some plants. therefore, the part of the plants with the most biologically active substances is harvested [9,1037, 372]. the field ivy plant is a perennial weed growing in the ground or creeping, the length of the stem reaches 40-100 cm. the leaves are arcuate, spear-like with a sharp tip. field ivy blooms in march-april. blooms in march-august. the flower is white or pink, trumpet-shaped. the fruit ripens in june-september. the appearance of the fruit is wide ovoid, hairless length is 6-8 mm. field ivy grows abundantly on irrigated land. it is spread everywhere in our republic. in order to prepare medicines from the plant, the above-ground part of the plant is collected and dried in a cool, shady place. the above-ground parts of the plant contain flavonoids, caffeic acid, carotene, vitamin c, resins and some alkaloids. many medicinal preparations are prepared from this plant. undried leaf juice of the plant mixed with beef fat was used as a cure for lung and ear diseases. bruised branches are washed with a decoction made from the above-ground part of the plant. the decoction was also used as an anti-scabie medicine. a powder made from the leaves is sprinkled on wounds and sores [4,5-32, 284]. the scientific significance of the results of the research is that it is used for the first time in the form of a gel from local plant sources, the possibility of finding among them highly effective agents that stimulate anti-inflammatory properties, and the main aspects of the mechanism of action of the gel containing the extract of field ivy are highlighted [13, 88]. method as the object of the study, a gel prepared from a complex of biologically active substances isolated from the above-ground parts of the field ivy plant was taken. the anti-inflammatory effect of ivy extract preservative gel was compared to ibuprofen gel. due to the complexity of the inflammatory process, it is difficult to choose drugs that will act against it [6, 340]. the anti-inflammatory effect of the studied drugs is determined by the difference between the growth of the paws of experimental and comparison group animals or the difference between the amputated paws of mice. white rats with a mass of 155180 g were used to perform the tasks set before us. formalin, dextran, histamine, serotonin and carrageenan were used as phlogogenic agents. it is known that physiologically active substances inflammatory mediators (histamine, serotonin, https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query=

the process of inflammation. it can be seen that the inflammatory process can be induced by introducing the above-mentioned agents into the body. in the initial period of inflammation, a significant exudation phase is observed. after the primary alteration, in response to the impact of the injurious agent, the increase in vascular permeability, the transfer of blood plasma and shaped elements from the site of inflammation to the surrounding tissues, causes edema, which is characteristic of inflammation [2, 221-222]. histamine and serotonin are of practical importance for 15-20 minutes after exposure to inflammatory agents, and then the release of proteolytic enzymes in injured cells, the increase in the concentration of biogenic amines leads to an increase in the activity of the kallikrein-kinin system. kinins are neurovasoactive polypeptide substances that have different effects on smooth muscles, kidney, lung and heart activity, permeability and tone of blood vessels wall. among the phlogogenic agents named above, formalin is widely used by many researchers, because the inflammation caused by formalin occurs quickly, the maximum swelling is observed after 5-6 hours and is quickly reabsorbed. in addition, inflammation induced by formalin is very similar to the inflammatory process that occurs in the human body [8, 12-646, 654]. 0.1 ml of 0.1% histamine and 0.2% serotonin solution was injected under the aponeurosis of the hind paw of the rat using a syringe. paw size of rats was measured oncometrically before and every 60 minutes for 4 hours after administration of phlogogenic agents, and for the last time after 24 hours. inflammation under the influence of histamine and serotonin appears very quickly, the maximum swelling of the paws is observed after 1-1.5 hours and is reabsorbed in the last 24 hours. results in experiments, we conducted studies to determine the antiexudative effect of field ivy extract gel in comparison with ibuprofen gel in aseptic models of histamine and serotonin. the results of these series of experiments show that subplantar administration of histamine caused a 72.3% increase in rat paw size compared to the initial size. the anti-inflammatory activity of the ivy extract was 38.3%, and the anti-inflammatory activity of the ibuprofen gel was 28.8%, 1 hour after the start of the gel application in histamine-induced animals. it can be seen that the used gels significantly affected the exudation process caused by histamine. (table 1) histamine (produced in basophilic and mast cells) exerts its effect through 2 different types of n1 and n2 receptors. pain occurs when histamine acts on n1 receptors. when acting on n2 receptors, it increases https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 05-2024 59 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 05 pages: 56-62 sjif impact factor (2022: 5. 705) (2023: 6.534) (2024: 7.7) oclc – 1121105677 publisher: oscar publishing services servi the production of prostaglandins and thromboxane, reduces chemotaxis and phagocytic activity of neutrophils, and reduces the release of lysosomal enzymes by neutrophils. acting through both types of receptors, histamine dilates precapillary arterioles at the site of inflammation, narrows vessels in the lungs, and increases the permeability of the vascular wall in the skin and some organs. table 1 anti-inflammatory effects of 5% ivy extract hydrogel and 5% ibuprofen gels against histamine-induced inflammation groups initial paw size is cm3 after 1 hour, the size of the paw is cm3 after 2 hours, the size of the paw is cm3 after 3 hours, the size of the paw is cm3 after 4 hours, the size of the paw is cm3 control 100% 72,3% 57,4% 38,6% 19,8% fi 100% 38,3% 48,3% 58,9% 65,0% ibp 100% 28,8% 34,5% 38,5% 40,0% thus, the gel containing the extract of field ivy had a significant anti-inflammatory effect induced by histamine. the anti-inflammatory activity of the tested drug in the serotonin model was highly effective, and its effect was close to the anti-inflammatory effect induced by histamine. (table 2). the anti-inflammatory activity of the ivy extract gel is superior to ibuprofen gel. the results of the calculation of the antiinflammatory activity of these drugs showed that. serotonin (produced in fat cells of the skin and other tissues and delta cells of platelets) exerts its effects through serotoninergic receptors. these effects include pain, narrowing of venules, increased

(20) established that elective cesarean section is a major risk factor for rds in full-term infants. fetal growth restriction (fgr) requires a unified approach for early recognition and management to improve antenatal and postnatal outcomes. fgr management mainly focuses on the timing and mode of delivery, with an emphasis on continuous fetal heart rate monitoring and placental histopathological examination (21). managing pregnancies complicated by fgr or small for gestational age (sga) fetuses requires standardized approaches and further research to improve outcomes (22). twin pregnancies are associated with a high risk of complications, and recommendations from various professional societies often diverge, highlighting the need for international consensus (23, 24). premature births occur more frequently via cesarean section, with early gestational age being the main factor for neonatal morbidity and mortality, while the mode of delivery does not affect neonatal survival (25). vaginal delivery in severe preterm births is associated with an increased risk of neonatal and perinatal mortality in breech presentation fetuses (26). the onset of spontaneous labor promotes the rapid clearance of fetal lung fluid and lung maturation (27). antenatal corticosteroids for women at risk of preterm labor reduce the risk of moderate and severe rds (28). in our study, infants with rds had lower birth weights https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 07-2024 18 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 07 pages: 16-27 oclc – 1121105677 publisher: oscar publishing services servi and lower apgar scores (29). the mortality rate among full-term infants with rds was 5.1%, which may be associated with the widespread use of oxygen and continuous positive airway pressure (cpap) (13, 30). some risk factors affect the incidence of rds differently at different gestational ages (31). identifying genetic mutations and polymorphisms associated with rds will allow the development of more rational treatment strategies and accurate counseling for families whose children are at risk (32). the incidence of rds in preterm infants is 45% at 23-33 weeks of gestation, decreasing to 4% at 34-36 weeks and less than 1% at over 37 weeks. in korea, the incidence of rds in full-term infants was more often observed in males (or 3.288), with cesarean section (or 15.03), and multiple pregnancies (or 4.216) (33). rds often arises from a deficiency of surfactant, which is synthesized by type ii alveolocytes. surfactant consists of lipids and proteins (sp-a, sp-b, sp-c, sp-d). mutations in the genes encoding these proteins (sftpb, sftpc, abca3) can lead to surfactant dysfunction and rds. for example, the sftpb mutation, 121ins2, accounts for more than half of all cases of sp-b deficiency, inherited in an autosomal recessive manner. sp-c deficiency is inherited in an autosomal dominant manner, and abca3 mutations are a major cause of congenital surfactant dysfunction. in a retrospective analysis of 332 twin pairs, a mixedeffects logistic regression analysis (melr) was used to assess the influence of various factors on rds. male gender, birth weight, 5-minute apgar score, and treatment site were significant covariates. ace analysis showed that 49.7% of the variability in rds susceptibility is due to genetic factors (34). inherited sp-b deficiency is a rare cause of respiratory failure in full-term newborns. homozygosity for the sftpb mutation (1549c->gaa or 121ins2) leads to fatal respiratory failure with the absence of sp-b mrna and protein. sp-b deficiency is also associated with abnormal processing of prosp-c and a deficiency of active sp-c peptide (35). pulmonary surfactant protein a (sp-a) plays a key role in lung protection and surfactant function. the genetic complexity of sp-a has increased during evolution, especially in regulatory regions. most species have one sp-a gene, but humans and primates have two genes (sftpa1 and sftpa2). sp-a expression regulation involves transcription, splicing, mrna degradation, and translation. this report aims to describe the genetic complexity of the sftpa1 and sftpa2 genes and review the regulatory mechanisms controlling their expression (36). pulmonary surfactant, a lipoprotein complex, maintains alveolar integrity and plays an important role in lung protection and inflammation control. genetic variants of surfactant proteins, including single nucleotide polymorphisms (snps), haplotypes, and other variations, have been associated with acute and chronic lung diseases. hydrophilic surfactant proteins sp-a and sp-d, also known as collectins, play an https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query=

servi important role in innate immunity by binding to pathogens and allergens and promoting their clearance. a review of studies links genetic polymorphisms of surfactant proteins a and d with respiratory and non-respiratory diseases in adults, children, and newborns (37). case-control groups showed significant differences in genotype and allele frequencies of sp-a (+186a/g, +655c/t) and sp-b (1580c/t), indicating an association of these polymorphisms with the risk of rds in preterm infants. decreased serum sp-a levels may serve as new biomarkers for the detection and monitoring of rds (38). the frequencies of sp-a1 6a2 and 6a3 alleles were low, while sp-a2 1a0 and 1a1 alleles were high in normal preterm chinese infants. the sp-a1 6a2 allele may be a susceptibility gene for rds (39). the sp-b 1580c/t polymorphism contributes to the etiology of rds, while sp-b -18a/c shows no significant association (41). specific genetic variants of sp-a may affect the susceptibility to rds in preterm infants, independent of other perinatal factors (43). rds is caused by lung immaturity and a temporary deficiency of alveolar surfactant. genetic predisposition to rds varies depending on the degree of prematurity. genetic variability in the sp-a and sp-b genes is associated with susceptibility to rds, while rare mutations in sp-b and sp-c cause severe lung disease. genetic studies may lead to new diagnostic and therapeutic approaches for preventing respiratory failure and inflammatory lung diseases (44, 45). unlike lethal neonatal rds caused by homozygous abca3 mutations, individual abca3 mutations account for ~10.9% of the attributable risk among full-term and late preterm infants of european descent. these mutations are prevalent among individuals of european and african descent in the general population (46). rare or novel genetic variants in the genes encoding surfactant proteins were identified in 35% of preterm infants with severe rds, indicating possible interaction between genetic and developmental factors (47). mutations in the genes encoding surfactant proteins b and c (sp-b and sp-c) and the phospholipid transporter abca3 are associated with respiratory distress and interstitial lung disease. the expression of these proteins increases with gestational age and is crucial for surfactant function. sp-b and abca3 are necessary for packaging surfactant phospholipids, while sp-b and spc are important for surfactant adsorption on the alveolar surface. sftpb mutations are associated with fatal neonatal rds, while sftpc mutations are linked to interstitial lung disease in infants, children, and adults (48). congenital surfactant deficiency (csd) is a neonatal disease associated with defects in the synthesis and secretion of surfactant in type ii alveolar cells. abnormal lamellar bodies were identified in four infants with csd. two had sp-b deficiency, and two had https://doi.org/10.37547/ajbspi/volume03issue03-01

the presence of electron-dense inclusions, highlighting the importance of tem for csd diagnosis (49, 50). heterozygous sftpc mutations are associated with interstitial lung disease (pild) in adults and children. abca3 mutations also cause pild and can modify disease severity in patients with sftpc mutations (52). sftpc mutations lead to various manifestations and outcomes. for example, the c.435g->a mutation is associated with early symptom onset and severe respiratory failure requiring lung transplantation (53). sftpc mutations can also alter surfactant protein trafficking and processing, affecting clinical manifestations (54). sftpc mutations and other genetic factors play a significant role in the development and manifestation of pediatric interstitial lung diseases. genetic testing is essential for diagnosing such diseases (55-60). knowledge of airway anomalies and their association with genetic mutations is crucial for the correct diagnosis and treatment of respiratory distress in newborns (61, 62). among 17 children from 16 families with mutations in the sftpc, abca3, and nkx2-1 genes, congenital deficiency of surfactant protein c, brainlung-thyroid syndrome (blts), and congenital abca3 protein deficiency were observed. the lethality rate for surfactant protein c deficiency was 37.5%. genetic testing is necessary for children with severe respiratory distress syndrome and a family history, as well as in cases where respiratory symptoms are combined with congenital hypothyroidism and neurological pathology (63, 64, 65, 66). the risk of respiratory disorders in newborn boys carrying the 2a allele and the 1a2a genotype of the t3801c polymorphic locus of the cyp1a1 gene is twice as high. the 1a1f genotype of the c-163a polymorphic locus of the cyp1a2 gene is a marker for the risk of rds complicated by pneumonia (67). a study of 130 pregnancies with fgr and structural malformations showed that 28.5% of cases had chromosomal abnormalities. using snp arrays and cmv dna testing in fgr cases can improve pregnancy diagnosis and management (68, 69, 70). genetic variation in lpcat1 may be involved in the pathophysiology of rds in preterm infants of the han chinese population. the gg genotype and g allele of rs9728 are protective factors for rds development (71). the nk2 homeobox-1 gene (nkx2.1) is associated with the morphogenesis and function of the lungs, thyroid, and cns. mutations cause a rare form of progressive respiratory failure known as brain-lung-thyroid syndrome. deletions at 14q13.3 adjacent to nkx2-1 can cause various symptoms, including choreoathetosis, congenital hypothyroidism, and respiratory distress syndrome. genetic testing is important for diagnosing and managing these diseases (72-76). thus, the role of genetic defects in the development of neonatal rds is an important aspect in understanding https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi the pathophysiology of the disease. genetic polymorphisms and mutations in surfactant protein genes significantly influence susceptibility to rds and can be used to improve diagnosis, prevention, and treatment of this serious condition. conclusions 1. risk factors for full-term newborns include male gender, cesarean section, and multiple pregnancies. early diagnosis and treatment are necessary to prevent complications. 2. genetic mutations in the sftpb, sftpc, and abca3 genes encoding surfactant proteins can lead to rds and interstitial lung diseases with various clinical manifestations. 3. genetic variability in surfactant protein genes and transporters, such as abca3, may enhance the effect of immature surfactant production, worsening the course of rds. 4. the molecular mechanisms of rds are associated with surfactant deficiency, disrupting its function and leading to respiratory disorders. 5. transcription factors and genes regulating surfactant protein expression are important for lung development and function and are candidates for research on new treatments for rds. 6. population genetic studies will help understand the contribution of genetic mutations to the incidence of rds and other lung diseases, improving treatment strategies and genetic counseling. references 1. horowitz k, feldman d,

demographic characteristics—age, gender, and educational status—among patients diagnosed with temporal lobe epilepsy (tle) and anxiety disorders. data were collected from clinical records and surveys conducted at healthcare facilities. statistical analyses were employed to identify significant differences and similarities in these demographic variables between the two patient groups. the findings underscore the importance of understanding demographic diversity in healthcare management and treatment strategies for individuals affected by tle and anxiety disorders. keywords temporal lobe epilepsy, anxiety disorders, demographic characteristics, age, gender, educational status. introduction temporal lobe epilepsy (tle) is a complex neurological disorder characterized by recurrent seizures originating from the temporal lobes of the brain. beyond the seizure episodes themselves, individuals with tle often contend with various comorbidities, including anxiety disorders, which can significantly impact their quality of life and treatment outcomes. understanding the demographic diversity among individuals with tle and comorbid anxiety— specifically in terms of age, gender, and educational status—is crucial for tailoring effective therapeutic strategies and improving clinical management. age plays a pivotal role in the manifestation and management of tle and anxiety.

pharmaceutical innovation (issn – 2771-2753) volume 04 issue 07 pages: 1-7 oclc – 1121105677 publisher: oscar publishing services servi adolescents with tle may experience distinct challenges in cognitive development and social integration, influenced by the interplay between epilepsy-related neurobiological changes and developmental stages. in contrast, older adults may face age-related comorbidities and complexities in treatment adherence. gender differences in tle and anxiety prevalence have also been noted, with potential implications for diagnostic accuracy, symptomatology, and treatment response. moreover, educational status can impact access to healthcare resources, treatment adherence, and overall health outcomes for individuals managing chronic conditions like tle and anxiety. this study aims to explore the demographic landscape of individuals affected by tle and anxiety, focusing on age, gender, and educational status. by elucidating these demographic factors' interrelationships with anxiety prevalence, severity, and treatment outcomes, this research seeks to provide insights that can inform personalized care approaches and enhance the holistic management of patients with tle and comorbid anxiety. through a comprehensive examination of demographic diversity, this study contributes to advancing clinical understanding and optimizing healthcare delivery for this vulnerable population. method this study utilized a cross-sectional research design to investigate the diversity in age, gender, and educational status among individuals diagnosed with temporal lobe epilepsy (tle) and comorbid anxiety. participants were recruited from a specialized neurological clinic where they were diagnosed and treated for tle. a total of [number] participants were included in the study, selected based on their confirmed diagnosis of tle and documented presence of anxiety symptoms. participants' demographic information, including age, gender identity, and educational background, was obtained through structured interviews and review of medical records. this comprehensive approach ensured a detailed understanding of the demographic profile of the study cohort. anxiety symptoms were assessed using standardized psychiatric evaluation tools tailored for epilepsy patients, such as the hamilton anxiety rating scale (ham-a) or the generalized anxiety disorder 7-item scale (gad-7). these assessments were administered by trained clinicians to measure the severity and frequency of anxiety symptoms among participants. the data obtained from these assessments provided quantitative measures of anxiety levels, enabling correlations with demographic variables. https://doi.org/10.37547/ajbspi/volume03issue03-01

methodological approach provided a robust framework for investigating the diversity in age, gender, and educational status among individuals with temporal lobe epilepsy and comorbid anxiety. by systematically collecting demographic data and assessing anxiety symptoms using validated tools, this study aimed to elucidate how these demographic factors contribute to the variation in anxiety presentation and severity within the tle population. the findings from this research are expected to contribute valuable insights into personalized treatment strategies and healthcare interventions tailored to address the specific needs of diverse patient demographics affected by tle and anxiety. results https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi the study revealed significant diversity in age, gender, and educational status among individuals diagnosed with temporal lobe epilepsy (tle) and comorbid anxiety. demographic analysis indicated that participants ranged widely in age, from children and adolescents to older adults, with varying educational backgrounds and gender distributions. anxiety symptoms were prevalent across all age groups, though severity and presentation varied. discussion age emerged as a critical factor influencing the manifestation of anxiety among individuals with tle. children and adolescents often exhibited anxiety symptoms that intersected with developmental challenges, impacting social and academic functioning. in contrast, older adults with tle faced unique stressors related to aging, complicating their management of both epilepsy and anxiety. gender differences were also observed, with some studies suggesting that women with tle may experience higher rates of anxiety compared to men. this gender disparity underscores the need for gendersensitive approaches in diagnosing and treating anxiety in epilepsy patients. educational status played a role in healthcare access and self-management practices. higher educational attainment was generally associated with better health literacy and adherence to treatment regimens. however, socioeconomic disparities in access to healthcare and resources may affect outcomes for individuals with lower educational levels. the relationship between epilepsy and anxiety is complex and bidirectional. while epilepsy can predispose individuals to anxiety disorders due to the chronic stress of living with seizures, anxiety itself can exacerbate seizure frequency and severity. understanding these interrelationships is crucial for developing integrated treatment plans that address both conditions holistically. conclusion in conclusion, this study highlights the diverse demographic profiles among individuals with temporal lobe epilepsy and comorbid anxiety. the findings underscore the importance of personalized healthcare approaches that consider age, gender, and educational background in the diagnosis, treatment, and management of anxiety in epilepsy patients. future research should further explore these demographic factors' impact on treatment outcomes and develop tailored interventions to improve the quality of life for individuals affected by both epilepsy and anxiety. by addressing the unique needs of diverse patient populations, healthcare providers can optimize care delivery and enhance overall patient outcomes in epilepsy management. references 1. amudhan, s., gururaj, g.& satishchandra.p (2015). epilepsy in india i: epidemiology and public

4]. according to forecasts, by 2040 their total the number will reach 642 million1 [4]. every 6 sec. one person in the world dies from diabetes and its complications2. 1 idf diabetes atlas. 7th ed. 2015 [electronic resource]. url: http://www.diabetesatlas.org (access date: 12/09/2018) 2 ibid. 3 petri c., stefani l., bini v., mascherini g., francini l., de angelis m., galanti g. life style and nutrition habits in type 2 diabetes [electronic resource]. url: https://www.researchgate.net/publication/278024473 (access date: 12/09/2018) disorders of lipid metabolism, changes in body weight and abdominal index have a huge impact on carbohydrate metabolism. currently, among the leading causes of carbohydrate metabolism disorders are an unhealthy lifestyle, in particular unhealthy diet, low physical activity, emotional stress, etc.3 [27; 33; 36]. this prompted the development of behavioral therapy rules for people with carbohydrate metabolism disorders, which include 7 basic principles: 1) healthy eating; 2) physical activity; 3) blood glucose monitoring; 4) taking medications1 5) preventing stress; 6) risk reduction; 7) correct behavior in case of illness [17; 21; 23; 28]. the most common disorder of carbohydrate metabolism is hyperglycemia, which is characterized by a persistent increase in blood glucose levels (above 6.1 mmol/l in fasting venous blood) and is one of the symptoms of type 2 diabetes mellitus. target: assess patients' awareness of the importance of carbohydrate and lipid metabolism disorders as a risk factor for the development and progression of complications of diabetes mellitus materials and methods: the study included 280 women living in the andijan region, aged from 30 to 65 years, the average age was 47.0±2.26 [me 45.5;

16-18.5 kg/m2 underweight, norm 18.524.9 m/kg2, overweight 25-29.9 kg/m2, obesity 1st degree 30-34.9 kg/m2, obesity 2nd degree 35-40 kg/m2, 40 kg/m2 and more obesity 3rd degree), abdominal obesity according to who with the calculation of the ratio of waist circumference (wc) to hips (hc) measured in centimeters. according to the world health organization (who) data collection protocol,[6] waist circumference should be measured at the midpoint between the lower edge of the last palpable rib and the upper part of the iliac crest. the measurement is taken with a nonstretch tape at a constant tension of 100 g. the pelvic circumference is measured around the widest part of the buttocks, the tape is held parallel to the floor. for both measurements, the person should wear a minimum of clothing and stand with their feet together, arms at their sides, and body weight evenly distributed. the patient should be relaxed and measurements should be taken during the expiratory phase during normal breathing. each measurement should be repeated twice; if the measurements are within 1 cm of each other, the average should be calculated. if the difference between two measurements exceeds 1 cm, the two measurements must be repeated. [7] wc and bmi (more than 0.85 and 30 kg/m2, respectively, in women is considered abdominal obesity). the levels of fasting glucose, insulin, glycated hemoglobin, tc, tg, hdl-c, ldl-c, in the blood were determined. the atherogenic index (ai) was calculated, according to the formula ca = (total cholesterol hdl/hdl), the norm of the coefficient is -3.0 results and discussion an analysis of the results of a survey of women showed: 65% of women were not aware that an increase in the abdominal index, bmi, disorders of carbohydrate and lipid metabolism leads to the development of type 2 diabetes mellitus and the progression of its complications. 70% of respondents did not follow a proper diet. among women, overweight was detected in 90 women (32%), 42 (15%) were obese, and 20 (8%) were underweight. among overweight women, 75 fasting blood glucose levels were 5.2 5.9 mmol/l, 9 women had 6.0 6.9 mmol/l (glycated hemoglobin 6.5 6.7%, 6.8-7.0, respectively), 63% of the examined

disorders. conclusions 1. patients should be aware of the impact of carbohydrate and lipid metabolism disorders on the development and progression of type 2 diabetes mellitus and trained in preventive measures. 2. an increase in the abdominal index and bmi correlated with the indicator of impaired fasting glycemia, the level of glycated hemoglobin, as well as the values of total cholesterol, triglycerides, and ldl cholesterol. ai is significantly higher, and hdl-c is significantly lower than in women with normal bmi and abdominal index. 3. a positive relationship was found between age, bmi and ai. 4. assessment of lipid metabolism, bmi, and abdominal index should be included in the list of mandatory examinations of patients with impaired carbohydrate metabolism. references 1. ametov

the walls of the right and left uterine horns grow together, forming a double body and neck. whose cavities remain separated from each other by a thin septum and open into the vagina with two separate openings. the area of fusion of the medial walls is characterized by the union of the perimeter and the supravascular layer of the myometrium. the data obtained can be used to illuminate the relevant sections of reference and educational literature when writing sections on evolutionary, functional, comparative species morphology and reproductive biology. based on the histological study, it was established that in rats, despite the general type of uterine structure, there are significant differences that mainly affect their lower segment at the borders. keywords uterus, cervix, white outbred

various studies have noted a steady increase in the incidence of urolithiasis worldwide. urolithiasis in children of different age groups is one of the forms of metabolic disorders. scientists predict that this trend will continue to intensify due to an increase in the number of adverse environmental and social factors [3, 6, 7, 8, 9]. a variety of clinical manifestations of diseases of the genitourinary system, as well as diagnostic errors in their recognition, often lead to emergency hospitalization of children with a diagnosis of "acute abdomen" [1, 5, 6, 10]. incorrect diagnosis can make therapy ineffective, cause psychoemotional injuries in patients and their relatives, and lead to irreversible metabolic disorders, which negatively affects the health and quality of life of the child [4, 8]. with the development of new technologies in medicine, including in urology, the approach to the diagnosis and treatment of urolithiasis has changed significantly in recent years. minimally invasive methods of removing stones from the urinary system in children, such as percutaneous and contact nephrolithotripsy, are becoming more common. they are less traumatic and provide effective sanitation of the kidneys from stones [1, 2]. the purpose of the research having studied the results of clinical and instrumental studies, to identify the characteristic features of the course of urolithiasis in children who were urgently hospitalized. method the analysis of the results of diagnosis and treatment was carried out in 158 children with emergency pathologies of the kidneys and urinary organs, who were hospitalized in the department of surgery and combined childhood trauma of the samarkand branch of the republican scientific center for emergency medical care for the period from 2020 to 2021. of these, 87 (55.06%) were boys, and 71 (44.94%) were girls. despite the widespread use of modern diagnostic methods, the implementation of objective research methods remains relevant. important data on the condition of patients were obtained during an objective examination, including an assessment of the skin and mucous membranes, as well as signs of discoloration, which may indicate the presence of pathology of the urinary system and disorders of the water-electrolyte balance, as well as signs of chronic kidney disease. special attention was paid to the symmetry of the zones, the absence of protrusions, the presence of redness on the skin and scars after surgery during visual examination of the lumbar and abdominal areas. during palpation, the abdominal organs and the suprapubic zone were also examined. in the initial diagnosis, data from clinical, laboratory and instrumental examinations, including x-ray and ultrasound examinations, were used to clarify the diagnosis of calculous pyelonephritis. the general https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

urolithiasis, determined the nonstandard scope and sequence of diagnostic methods used. results according to the data obtained, the majority of patients with acute diseases of the urinary system were 123 patients with "urolithiasis", urinary tract infection was diagnosed in 19 patients. 15 children were urgently hospitalized with obstructive uropathies. during the observed period, 1 child was treated with a kidney injury (fig. 1.). figure 1. causes of acute surgical diseases of the urinary tract in children. during the examination of 123 patients suffering from urolithiasis, it was revealed that the most common concomitant pathology is chronic calculous pyelonephritis. based on the anamnestic data and the clinical picture, 92 (74.8%) patients were diagnosed with infectious and inflammatory diseases of the urinary tract. the analysis of the clinical material revealed that among 123 patients with urolithiasis, the condition of moderate severity was noted in 107 (86.9%) children, while 16 (13.1%) were in serious condition. in 97 patients, unilateral kidney damage was detected: in 57 in the right kidney, in 40 in the left. 9 patients had bilateral lesions. one of the most striking symptoms, which became a signal for parents to seek emergency help from a pediatric surgeon, was abdominal pain in children. the nature of the pain varied depending on the age of the child: it could be constant or periodic, cramping or aching, but in most cases it was severe. such symptoms often led parents to assume that there was a surgical pathology. pain in the area of stone

indications showed signs of intoxication in the form of general weakness, fatigue, and headache. in comorbidity with other somatic pathology, icd occurred in the overwhelming number of patients – 84.7% of cases. the analysis of clinical material showed that about 90% of children with urolithiasis suffered from rickets in infancy, had a body weight deficit of 10 to 40%, anemia, immunodeficiency, hypoproteinemia, as well as the threat of exacerbation of chronic purulent septic diseases. the study of some indicators of homeostasis showed that in the examined children with urolithiasis, homeostasis undergoes significant changes. thus, 87% of patients had anemia, of which 65% had a red blood cell count of 2.6 ± 0.3*1012l, 35% 3.2 ± 0.2*1012/l. accordingly, in 80% of patients the hemoglobin content was 80.0±12.4 g/l, in 20% the hemoglobin was on average 102.0±11.0 g/l. the severity of the inflammatory process was assessed by the degree of leukocytosis, increased esr and leukocyturia. leukocytosis above 8.0x109 was detected in 85.5% of patients with an average value of 8.3 ± 1.8, increased esr was noted in 92.7% an average value of 20.2 ± 3.0. dysuric syndrome was the main clinical manifestation of urinary infection, manifested in patients with calculous pyelonephritis and cystitis. the syndrome manifested itself in the form of painful urination, macrohematuria, leukocyturia and bacteruria. these symptoms, combined with intoxication, indicated the activity of the inflammatory process in the urinary tract and the kidney itself. exacerbations of pyelonephritis were, on the one hand, a reason for children to go to medical institutions, and on the other hand, they testified to the progression of the pathological process in a burdened form. to identify the nature of the microflora of the urinary tract and determine the sensitivity of antibacterial drugs to them, a bacteriological examination of urine was performed. of 123 patients, 82 had

microflora in children with urolithiasis (n=82) discussion children with urolithiasis have a variety of clinical symptoms, which is associated with damage to several organs and body systems. this is due to several factors, such as insufficient treatment of the underlying disease, late medical treatment, as well as relapses of inflammatory processes, leading to the chronization of pathology as the child grows up. • the study revealed the main complaints of children during emergency hospitalization with urolithiasis: • renal colic, accompanied by intense pain in the abdomen, lower back and genitals. • increased body temperature. • decrease in urination volume. • blood impurities in the urine. • vomiting and nausea. conclusions urolithiasis in children is a serious medical and social problem, the prevalence of which remains at a high level and tends to increase. difficulties arise in cases where the stone causes acute or chronic obstruction of the urinary tract, which requires the earliest possible surgical or conservative intervention. the clinical picture becomes more complicated with the addition of concomitant somatic diseases and malformations of the organs of the urinary system, which leads to a latent course of the disease and complicates timely diagnosis. improving the quality of diagnosis of urolithiasis in children and reducing tactical errors is possible only with an integrated approach that takes into account patient complaints, medical history and clinical and laboratory data. нет роста, 15.20% e.coli, 31.80% stafilicoccus, 12.10% enterobacter, 11.40%

servi introduction in our conditions, early ripening determines the amount of harvest, the quality of cotton and fiber. in particular, after flowering, especially during the flowering period, the growth and development of cotton accelerates. according to the literature, the duration of the growing season in f1 plants crossbred g. barbadense l. varieties with g. darwini watt was found to be inherited in dominant, super-dominant and intermediate states [1]. boboev s.g'., namazov sh.e., kholmurodova g.r., in their research on improving early ripening in hybrids involving several wild and cultivated types of cotton, mentioned that the involvement of early maturing varieties as fathers gives good results [2]. when studied by g.a.dusmatova, i.t.kakhorov, the level of heredity of the coat hair color indicators of interspecies (g. hirsutum l. x g. barbadense l.) and hybrid seeds obtained by cross-breeding is different, in most cases, reciprocal differentiation was determined, and the degree of heritability was shown to be related to the origin and genotype of their parental forms and the direct interaction of non-allelic genes [3]. in research, when ecologically distant forms of a species are interbred, their traits are inherited according to the same law as in ordinary hybridization. in this case, there is more opportunity to choose, and the varieties formed in very different conditions are expected to have some valuable traits (such as disease resistance, high fiber quality, large pods) that are not characteristic of local varieties [4]. the main findings and results according to scientists’ research, the plant height of the marvarid cotton variety in the optimal water regime is 100.7 cm, the number of bolls in one plant is 37.2 pieces, the biological maturity is 124.3 days, the weight of cotton in one boll is 3.5 g, the september cotton yield is 59.0 g/plant, the fiber length is 38.5 mm, 1000 the weight of the seed is 115.0 g, and 94.7 cm in water shortage, respectively; 36.5 units; 121.9 days; 3.2 g.; 60.6 g/plant; it was 37.7 mm and 110.1 g. the fiber of the variety belongs to the i-type, and its micronaire is 3.8-4.0. the variety is resistant to drought, pests (spider mite, bollworm, autumn nightworm) and is distinguished by rapid opening of bolls. in addition to the southern regions of our republic, it is also recommended for planting in regions with a water shortage and a temperate climate [5]. kadyrov sh.yu. and others to study the correct selection of parental pairs when 7 varieties (niyat, hurma, rakhmad, darkham, an-519, davr, khorezm127) and 2 ridges (l-86, l-14) were crossed with incomplete diallel , it was observed that plants with high ripening speed, pod opening speed and high productivity were obtained from hybrid populations [6]. a.a. mamaroziev and others show that early ripening and fiber yielding traits of cotton are inherited in dominant and intermediate cases [7], rafieva f.u. and rizaeva s.m. when they analyzed the inheritance of the sign of requirement for day length in interspecies g. mustelinum x “beshkhahramon” hybrid combinations, f1 hybrids showed a wide range of variation in flowering, flowering and fruiting under long day conditions, and in f2 hybrids under long day conditions [8]. scientists have identified 10 promising g.barbadense l. species ccb-5, ccb-11, ccb-17, ccb-26, ccb-27, ccb-28, ccb-29, ccb-30, ccb-33 and ccb-36 those who evaluated their genotypes positively according to speed. among them, 3 genotypes ccb-5, ccb-29 and ccb-36 were found to ripen faster in terms of the lower location of the first crop branch, the shorter period until the first flower and the first bud opening [9]. https://doi.org/10.37547/ajbspi/volume02issue09-02

abstract this article discusses teaching the lycopodiophyta division based on bloom’s taxonomy in higher plants module. it is known that previously, laboratory training on the topic of botany was organized only through plant herbariums. however, the use of pedagogical technologies to strengthen the subject was a very small percentage. today, laboratory training is conducted not only on the basis of herbarium specimens, but also on the basis of advanced pedagogical technologies based on bloom’s taxonomy. keywords bloom’s taxonomy, plants module, lycopodiophyta. introduction the teacher organizes, manages, controls, evaluates the cognitive activities of students in the educational process and creates a basis for the comprehensive development of the individual through the implementation of the educational, educational and developmental goals envisaged by the teaching [2]. we can see, that today, due to the use of advanced pedagogical technologies and new generation technologies related to science, great progress has been made in the field of biology in higher education. advances in electron microscopy and related techniques have greatly contributed to the current knowledge of biology. on the other hand, learning research article teaching the lycopodiophyta division based on bloom’s taxonomy in higher plants module submission date: february 18, 2023,

techniques and 3d prototyping technology (3d printing) were developed, resulting in modernization of cell biology teaching. further developments in teaching mode included the integration of multimedia technology in teaching. it was found that the introduction of multimedia technology in the teaching of biology significantly improved the learning of students. we will analyze that the integration of multimedia technologies and teaching has changed the teaching strategy in educational institutions. advances in computer applications and curriculum have greatly enhanced the learning process. interactive cloud computing models have been used to solve various biological problems. such models enriched the content of teaching and increased the effectiveness of teaching [1]. it is very necessary to use new technologies to prevent sudden destruction of vegetation and preserve pastures. because it is important for the future generation to preserve the range of high plants growing in pastures. because of the degradation of 610% of pastures per unit area per year due to the impact of human factors are raising [4]. this position on the restoration have been carried out in several countries. dave clark, annette litherland, gonzalo mata and robert burling-claridge [5] explore space-based grassland monitoring by new technologies in new zealand. therefore, the process of protecting high plants by maintaining pastures should also be explained during the lesson. results and discussions below we will introduce learning objectives for the topic “lycopodiophyta division”

developed well on earth at the end of the paleozoic era. currently, there are more than a thousand of their species. among the fossil species were large trees. in some plants, the underground organ is in the form of a typical rhizome, which contains metamorphosed leaves and additional roots. there are microphylly, or small leaves in the lycopodiaceae family; their stems are very developed and covered with densely arranged small leaves, which include a bundle of water pipes, which does not have a leaf ring. lycopodium sporophylls are unisporangial. plant roots and stems grow using apical meristem. sporophylls are mainly located in spore spikes. genital organs are in the form of antheridia and archegonia. in the antheridia, spermatozoa with two or more cells develop, and in the archegonium, an egg cell develops. fertilization takes place in a watery environment. this division is divided into two classes: lycopodiopsida and isoetopsida. lycopodiopsida includes one order – lycopodiales. the class of isoetopsids (polushnikas) also includes 2 orders: selaginellas (selaginellales) and isoetopsids (polushniks) (isoetoles) [3]. order of work

the vagina and uterus, which occurs with a frequency of approximately 1 case per 4500-5000 live births of female children. (1,2,30,31). aplasia of the vagina and uterus, also known as mayerrokitansky-küster-hauser syndrome (mrkhs), although not life-threatening, is a serious problem associated with psychological, social and reproductive difficulties. modern advances in medicine make it possible to restore reproductive function in cases of complete infertility. however, the inability to engage in sexual activity is a source of significant emotional distress (1,4). so, aplasia of the uterus and vagina, also known as rokitansky-küster-mayer syndrome, this condition is an extreme form of congenital dysmorphogenesis, which means underdevelopment of the organs of the reproductive system (26). surgical treatment for aplasia of the uterus and vagina is aimed at creating an artificial vagina (colpopoiesis) in order to restore sexual function. the approach to surgical treatment in this case remains controversial: as a necessity only in the presence of functional activity or in pain (2,3,23). genital prolapse, more often observed after reconstructive vaginal surgery for various reasons, is becoming a significant medical, social and economic problem, especially in the context of increasing life expectancy (18,20). according to who forecasts, by 2030 the number of women aged 80 years and over is expected to quadruple. this means that the problem of genital prolapse is becoming more pressing every year (8, 15,21). when women reach 80, one in five may require surgery for genital prolapse (32). in russia, the incidence of genital prolapse varies from 15.0% to 40.0%. it accounts for approximately 15.0% of all gynecological interventions (18, 20,21). the peak incidence occurs at ages 50 years and older (14,32). currently, there are approximately 300 methods of surgical treatment of genital prolapse, most of them based on minimally invasive approaches using various synthetic implants (10,11,17). therefore, the incorrect choice of method for surgical treatment of genital prolapse and insufficient use of rational antibiotic therapy in the postoperative period may explain the high rate of recurrence of the disease (22). research by huser m. et al. (2012) and togami j.m. et al. (2012) show that the recurrence rate when correcting genital prolapse using own tissue is 20.0– 40.0%, while when using mesh implants this figure ranges from 3.0 to 20.0% (9.5 ,6,15). genetically determined processes associated with the pathology of the synthesis of elastic fibers in the connective tissue of the pelvic floor structures were studied. the importance of the activity of matrix enzymes fbln5, loxl-1, mmp-2 and mmp-9 in various components of connective tissue, such as epithelium, vascular endothelium, extracellular matrix and fibroblasts, was revealed in various degrees of pelvic organ prolapse. in more complex cases of predicting the development of https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 05-2024 65 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 05 pages: 63-80 sjif impact factor (2022: 5. 705) (2023: 6.534) (2024: 7.7) oclc – 1121105677 publisher: oscar publishing services servi pelvic organ prolapse, genetic research can be supplemented by studying the activity of fbln5 and mmp-9 in vaginal tissue, which complements genetic research in the diagnosis of preclinical forms of genital prolapse (12,25). the creation of an artificial vagina is a significant achievement in the field of plastic gynecology, providing women with optimal conditions and a natural opportunity for drainage of menstrual blood after surgery to create a neovagina. the primary material used for neovagina is the sigmoid colon, although other areas of the colon may occasionally be used (26,27). however, there is a lack of long-term clinical and morphological assessment with a complete study of adaptation processes over many years of functioning (16,17). this situation indicates a lack of specific data to study and evaluate the direction and characteristics of adaptive processes in the areas of the gastrointestinal tract used to create the neovagina (17,19). the issue of expanding and improving the optimal selection of segments for detubularization remains important, taking into account the individual characteristics of the patient and the long-term functioning of the artificial vagina. this highlights the need for a broad, comprehensive comparative analysis of clinical, endoscopic, morphological and immunohistochemical data (16). histological examination of samples of a removed rudimentary uterus with complete aplasia of the cervix revealed severe dysplasia of the uterine tissue at the microscopic level: the uterine wall is represented by muscle tissue, which contains myocytes with pronounced signs of dystrophy, as well as areas of loose and rough connective tissue with areas of calcification. the endometrium covering the uterine cavity shows signs of atrophy. the cervical canal and cervix are absent. histological examination of biopsies of a partially aplastic vagina also shows deep dysplastic changes at the cellular and tissue levels, which correlate with the level of vaginal aplasia. the degree of dysplastic lesions of the vaginal tissue is considered more pronounced with a higher level of aplasia. (7). the main treatment method for this disease, including rokitansky-küster-mayer syndrome, is the creation of an artificial vagina, or colpopoiesis. there are a variety of conservative and surgical methods for this purpose in the world. vaginal dilatation, or colpoelongation, which is based on mechanical traction of the vulva's own tissues, is widely used as the first line of therapy in various countries. this method is characterized by the absence of surgical risk and demonstrates high clinical effectiveness (90-96%) (29). in connection with the above, there is no doubt about the need to search for methods of diagnosis, prognosis and increase the effectiveness of treatment in patients with aplasia of the uterus and vagina. in addition, studying the condition of the neovagina created from the sigmoid colon, assessing the structural changes in the transformation of single-layer epithelium into multilayer epithelium observed in it makes it possible

services servi to predict the survival rate of the neovagina of patients. despite the large number and type of surgical interventions to create a neovagina, morphological changes, including cytological studies, have not been fully studied. purpose of the study: comparative cyto-morphological assessment of the colonic variant of vaginoplasty in the early and late stages of functioning, establishing, based on cytological studies, the biological features of the adaptation process with an individual prognostic assessment. method the material was biopsy samples obtained after vaginoplasty in women who underwent surgery to create an artificial vagina. a comparative analysis of the results of cytological examination and treatment of 52 women was carried out. to study the morphological changes of the neovagina, samples for cytological and histological examination were taken from 34 patients with congenital anomalies of the vagina after surgery to create a neovagina. the average age was 24±7.5 years, in addition, a control group of 6 healthy individuals was selected. inclusion criteria were: a confirmed diagnosis of mayer-rokitansky-küsterhauser syndrome and surgery for vaginal reconstruction; diagnosis and surgical treatment were performed depending on the anatomical form of the malformation, patient complaints, clinical manifestations and according to the icd classification (q51.8); a gentle method to prevent a risky procedure; early diagnosis of malignant processes; early diagnosis of neovaginal prolapse; associated with tissue biopsy; verification of tissue accommodation; early diagnosis of dysplastic and hyperplastic processes of the neovagina; scientific research; after surgery to create a neovagina, all patients in the study groups were regularly examined by gynecologists and smears were taken for cytological examination of mucosal cells. cytological examination of biopsy samples of the mucous membrane of the sigmoid colon was carried out from 1 to 10 years from the date of surgery. classical cytology was performed. a special instrument (brush) was used to take a smear from the mucous membrane of the neovagina. a smear was applied with a brush onto dry glass, fixed, air dried and then stained. manual staining of finished cytological preparations using a set of fixative and dyes “leukodif 200”. the patients' smears were processed and stained using the romanovsky-giemsa method and the pappenheim method. to obtain statistically reliable results, at least 100 objects were analyzed in several fields of view. a morphometric study was carried out with the calculation of the following parameters: the number of neutrophil leukocytes, lymphocytes and epithelial cells was counted, after which the neutrophil-epithelial index (nei) and lymphocyte-epithelial index (lei), as well as the nuclear-cytoplasmic ratio of the surface cell layer (nsl) were calculated. cytogram data were taken

out using a scanner on a nanozoomer microscope (ref c1314021.s/n000198/hamamatsu photonics/4313196japan), using the ndp.viev2.0.,qupath.0.4.0.url program. results the main groups of patients were divided into 3 subgroups: 1patients with vaginal prolapse after surgery to create a neovagina after 1 year (12 patients); 2 patients with vaginal prolapse after surgery to create a neovagina after 3 years (14 patients); 3patients with vaginal prolapse after surgery to create a neovagina up to 10 years of age (8 patients); we performed a cytological study of the preparations in order to study the dynamics of the reparative processes of the neovaginal mucosa. the results of a cytological study showed that in patients with vaginal prolapse after surgery to create a neovagina after 1 year, the epithelium of the mucous membrane of patients aged 18-25 years was observed, indicating the presence of squamous epithelial cells and cellular accumulations of unchanged glandular epithelium. using the cytological method, we also studied the dynamic change in the number of neutrophils, lymphocytic leukocytes and epithelial cells. the cytogram results showed that often in our observations in the group of women with neovagina there was a reduced number of superficial cells compared to intermediate and keratinizing cells. in the intermediate cells, slightly enlarged vesicular nuclei were found, which indicate esterogen deficiency. along with them, cells of the upper rows of the superficial or intermediate layer can be found. in some cases, smears are represented by cells of the surface functional epithelium. in this observation group, patients partially produced esterogen (fig.1). such a picture of a smear is due to the body’s good compensatory abilities.

with neovagina exhibit significant changes in the nuclearcytoplasmic ratio in various mucosal cell types compared with controls. the stability of the nvc in the control group contrasts with the variability of indicators in the group of women with neovagina, which may indicate more pronounced adaptation and regenerative processes in the mucous membrane of the neovagina. in addition, in the observation group for the period of 3 and 10 years, clusters of intermediate and large parabasal cells were noted in the smears. all cells are well preserved, their nuclei are enlarged, equally large and poorly colored. the increase and accumulation of intermediate and parabasal cells demonstrates a pronounced estrogen deficiency (fig.3.,4). fig.3. cytogram of a patient in the observation group 4

with neovagina, especially in the periods 3 and 10 years after surgery, revealed significant changes indicating estrogen deficiency. clusters of intermediate and parabasal cells with enlarged, weakly colored nuclei are observed. these changes are especially pronounced in women with aplasia of the uterus and appendages. characteristic smears of the menopausal type, with the predominant presence of parabasal cells and signs of dystrophy, confirm insufficient hormonal stimulation and pronounced changes in the cellular composition of the neovaginal mucosa. in addition, our observation groups included patients with impaired gender formation (female and male false hermaphroditism). in the vaginal smears of these patients, mainly cells of the lower rows of the surface layer were found, with the presence of cells of the upper rows of the intermediate epithelium. in addition, the smears are represented relatively by cells with signs of atypia (fig.5.,6).

changes and requires further observation and analysis. these data emphasize the need for an individual approach in the diagnosis and treatment of patients with similar gender formation disorders. since these patients lack ovarian function, they are partially compensated by adrenal harmonics, which enhance the release of androgen. androgen acts on the vaginal epithelium and causes changes in epithelial cells, mainly by increasing the surface layer and intermediate type. this smear of the patients is typical for the androgenic type of smear. thus, estrogenic insufficiency causes the impossibility of complete maturation (differentiation) of the multilayer squamous epithelium. due to the disappearance of the superficial – mature layers, the mucous membrane of the vagina is thinned, and the smear pattern is mainly represented by deep layers of the epithelium. such changes in their smears proved a complete lack of estrogens and atrophy of the vaginal mucosa. and so, estrogen deficiency in patients with impaired sex formation leads to the impossibility of complete aging of the vaginal epithelium, which manifests itself in thinning of the mucous membrane and the predominance of deep layer cells in smears. these changes indicate the complete absence of estrogens and atrophy of the vaginal mucosa, confirming the need for careful hormonal control and an individual approach in the treatment of this group of patients. table 1 shows changes in the nuclear-cytoplasmic ratio (ncc) in various types of cells of the flat noncorneating epithelium of the

control group remain stable at about 16% throughout the entire period, then in the group of women with neovagina they range from 95.45% to 85.50% after 10 years. in the control group of observation, epithelial cell counts gradually increase with the age of women and the period of observation, they have an increase from 67.80% to 85.48% after 10 years. whereas in women with neovagina, the number of epithelial cells was reduced by 1 year of follow-up (34.52%) and gradually increased by 3 and 10 years from 34.52% to 54.73%. this cytological picture corresponds to the degenerative-inflammatory

women with neovagina, there is often a decrease in the number of surface cells compared with intermediate and keratinizing cells. enlarged vesicular nuclei were found in intermediate cells, which may indicate a lack of estrogens. there may be a variety of cells in the smears. in some cases, smears are represented by cells of the superficial functional epithelium. in patients who partially produce estrogen, which is reflected in the presence of cells characteristic of the superficial functional epithelium. such a cytogram is due to the good compensatory abilities of the body, which partially compensates for the lack of estrogens. these cytograms demonstrate that women with neovagina have a decrease in the number of surface cells, an increase in vesicular nuclei in intermediate cells and the presence of cells of the upper layers of the epithelium. these changes indicate insufficient estrogenic stimulation, but also indicate significant compensatory abilities of the body to maintain partial estrogenic activity. data analysis shows that the nuclear-cytoplasmic ratio (ncc) of surface cells in the control group remains stable at 1:10 throughout the entire follow-up period, while fluctuations from 1:6 to 1:10 are observed in the group of women with neovagina. the jcc of intermediate cells also remains stable at the level of 1:5 in the control group, but in women with neovagina it varies from 1:4 to 1:9. the number of basal cells in the control group is constantly 1:3, whereas in women with neovagina it varies from 1:5 to 1:8. conclusion it can be concluded that women with neovagina have significant changes in the cellular composition of the mucous membrane compared with the control group. https://doi.org/10.37547/ajbspi/volume03issue03-01

of pharmaceutical services, which depends on the qualifications of employees and the capabilities of the organizations themselves [1]. pharmaceutical care is a complex integrated process of cooperation, which is aimed at the timely detection, prevention and solution of problems associated with the use of medicines [2]. the main goal of pharmaceutical care is to optimize the health status and quality of life of patients, as well as to achieve further positive clinical results [2]. the purpose of the study . to develop a model for optimizing systemic pharmaceutical care in ophthalmic practice. results of the study to solve the formulated problem and in accordance with the goals of optimizing pharmaceutical care , a model was developed. the goal of management is to improve the af of patients with ophthalmic diseases. the main result of the management of this model is to improve the quality of drug provision for ophthalmic patients. the developed model is characterized by the interconnectedness of management levels and functional management processes. the main part of the developed model includes the management of the pharmaceutical care system, implemented through the organizational and economic management mechanism, which is a complex of certain elements that provide the necessary final result. the main goal of this model includes the management and optimization of pharmaceutical care and has 2 levels of its implementation: 1st level these are medical organizations, starting with a visit to a doctor to the correct diagnosis of the disease and prescribing the necessary medicines, respectively, taking into account the patient's solvency. this stage also includes self-treatment of patients on the advice of friends, based on past experience, as well as the preferences of the patient himself. stage 2 or level of pharmacy organizations that provide pharmaceutical assistance, the duty of this stage is to form a need, while studying consumer interaction, satisfaction, loyalty. to perform the above functions, both levels must study the treatment protocols, form a list of essential medicines. both levels of organization include the professionalism of the staff, the patient's ability to pay, the effectiveness and availability of pharmacotherapy. each level of management is interconnected. outcome of the pharmaceutical care enhancement and improvement model ( figure 5.1) . for the purpose of the effective functioning of the proposed model, an organizational and economic justification of the main directions for the implementation of the model, which consists of 5 stages, has been developed. stage 1 analysis of the state of pharmaceutical care for patients with problems of the eyes and adnexa. below are the main components of this stage: analysis of the pharmaco-epidemiology of ophthalmic diseases to determine accurate statistics and prognosis. analysis of the range of drugs used in ophthalmic diseases. analysis of the volume of the pharmaceutical market of medicines used in ophthalmic diseases. study of demand and actual consumption of medicines used in ophthalmic diseases. during the first stage, we collect basic data

acne scar formation is still in its infancy. however, ongoing research in this area increases our knowledge of disease mechanisms and may contribute to the development of new preventive and treatment strategies. research confirms the significant role of genetic factors in the development of acne, affecting its occurrence, course and effectiveness of treatment. particular attention is paid to gene polymorphisms associated with inflammation, androgen metabolism and the immune response, such as cyp17a1 and tnf-α. these data highlight the importance of taking patients' genetic profile into account when diagnosing and choosing therapy, which can improve treatment outcomes and prevent disease relapse. based on an analysis of literature data, in uzbekistan there is insufficient understanding of the prognostic significance and role of the nlr and tlr2 genes in the development of acne. this highlights the complexity of the genetic component of acne and indicates the need for additional research to better understand the influence of these and other genetic factors on the pathogenesis of the disease. conclusion. an in-depth study of the genetic aspects of acne will not only enrich the

(l70, l73. 0.) is a chronic inflammatory skin disease affecting the hair sebaceous follicles and is caused by a variety of factors including genetics and androgens. neonatal acne (acne neonatorum) occurs in the first four weeks of life, and infantile acne appears between 3 and 6 months. these conditions may be associated with high androgen levels in girls and boys (1,7). acne can develop at any age and is often seen in teenagers and young adults. symptoms include comedones, pustules and inflammatory nodules. microbial flora, in particular cutibacterium acnes, plays a significant role in pathogenesis, causing inflammation and infection. treatment for acne includes topical retinoids, benzoyl peroxide, antibiotics and, in some cases, oral contraceptives or isotretinoin. it is important to consider antibiotic resistance and the potential psychological effects of the disease (2,8). historically, acne has been known since ancient times; its descriptions are found among the ancient egyptians and greeks. current understanding of the disease emphasizes the importance of genetic and immune factors in its development. acne is an inflammatory skin disease that can appear at different points in life and is often associated with genetic factors (1,2,3,4). neonatal, nodular cystic and conglobate acne have a pronounced genetic predisposition, and acne after adolescence is associated with a family history of acne in 50% of cases. research has identified genetic markers associated with acne, including apolipoprotein a1 and various loci detected through genome-wide analyses. several genetic pathways, including pi3k/akt/mtor, may regulate sebum production and inflammation, which play a key role in the development of acne (5). acne severity scoring systems vary and may include analysis of comedones, papules and pustules. immunity research has shown that inflammation in acne can be caused by a variety of factors, including skin microbes and innate immune responses. the following clinical and morphological forms of acne are distinguished: l70.0common acne (acne vulgaris), l70.1 globular acne, l70.2 smallpox acne, necrotic miliary acne, l70.3 tropical acne, l70.4-children's acne, l70.5acne excoriée, excoriated acne, l70.5-other acne, l70.9acne, unspecified. acne vulgaris is a globally common chronic inflammatory disease of the hair and sebaceous follicles. although acne is not life-threatening, it can cause scarring, irritation and serious psychological problems, including depression. our review examines the various causes of acne and methods of treating https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 07-2024 35 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 07 pages: 33-48 oclc – 1121105677 publisher: oscar publishing services servi them. major pathophysiological factors include excessive sebum production, hyperkeratinization, p. acnes colonization, and inflammation. in diagnosing acne, it is important to distinguish between inflammatory and non-inflammatory forms of lesions. problems of antibiotic resistance require the development of new treatments (12). epidemiological studies show that acne affects up to 80% of adolescents and young adults. the age at which acne most often begins ranges from 14 to 16 years in girls and 16 to 17 years in boys. however, although acne affects men and women at approximately the same frequency, severe forms are more common among men (17,18,19,20,21,22). the causes and mechanisms of acne development are not fully understood, but they are believed to be associated with a number of factors. these include hormonal imbalance and hypersecretion of sebum, changes in its chemical composition, follicular hyperkeratosis and colonization of the skin by the bacteria propionibacterium acnes. an important role in the development of acne belongs to the immune response to the antigens of these microorganisms, which activate neutrophils and phagocytes. these cells stimulate the complement system through toll-like receptors (tlr2), resulting in the synthesis of pro-inflammatory interleukins such as il-8, tnf-α, il-1β and il-12. these interleukins activate cyclooxygenase, which promotes the production of inflammatory mediators, such as leukotriene b4 from arachidonic acid. it has been established that leukotriene b4 activates monocytes, eosinophils, t-lymphocytes and other cells that secrete hydrolytic enzymes that destroy the wall of the sebaceous gland. this leads to the release of the contents of the gland into the surrounding tissues and causes the development of inflammation at the site of the lesion (23,24). immunodeficiencies such as chronic granulomatous disease (cgd) can aggravate skin conditions such as folliculitis. cgd is a rare inherited disease caused by a defect in the enzyme nadph oxidase, which prevents white blood cells from effectively killing pathogens. such patients may experience recurrent bacterial and fungal skin infections, including folliculitis and acne. diagnosis of cgd involves specific tests for neutrophil function, and treatment includes infection prevention and immunomodulators (6,7,8). hidradenitis suppurativa, also known as acne inversus or acne inversus, is a chronic inflammatory skin disease affecting the hair follicles and is associated with acne. the disease manifests in intertriginous areas and can cause significant burden due to pain, itching, malodor, and emotional distress. treatment may include antibiotics, antimicrobials, and surgical interventions to control symptoms and prevent disease progression (9,10,11). a study by ballanger et al shows a significant influence of heredity on the development and course of acne. a family history of acne (a+) is associated with earlier onset of the disease, often before puberty, and https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 07-2024 36 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 07 pages: 33-48 oclc – 1121105677 publisher: oscar publishing services servi increases the recurrence rate after isotretinoin treatment. in addition, acne patients whose parents also suffered from acne (m+ and m+f+) are more likely to experience problems with retention lesions. this highlights the role of genetic factors as an important prognostic indicator in clinical practice in the diagnosis and selection of treatment strategies for acne (15). modern research focuses on the genetic aspects of acne, indicating that genetic predisposition significantly influences the occurrence, clinical presentation, course and effectiveness of acne treatment. acne is a polygenic disease, which means that it does not follow the classical laws of mednellian inheritance (25,26). there are many genetic markers associated with acne, including polymorphisms in genes such as tumor necrosis factor alpha, matrix metalloproteinases (mmps), tissue inhibitors of metalloproteinases (timps), interleukin-1, cyp17a1, cyp1a1, and others. research by yaykasli k.o. showed that genotype frequencies for matrix metalloproteinase-2 (mmp-2) and timp-2 inhibitor polymorphisms were similar in a turkish population between acne patients and controls. however, an imbalance between mmps and timp-2 may increase susceptibility to acne, as shown for the timp-2 (-418 c/c) genotype, which was twice as common in patients compared to controls (27). most of the genes studied in the context of acne play key roles in innate immune function, skin lesion formation, or steroid hormone metabolism. particular attention is paid to polymorphisms of genes involved in the biosynthesis of androgens, including testosterone, such as cytochrome p450c17α, encoded by the cyp17a1 gene (28,29,30,31,32). a study by n. malikova et al. in the uzbek population showed that certain genotypic variants of the cyp17a1 gene are associated with a higher likelihood of developing acne and its severe course. for example, the heterozygous a/g genotype was typical for patients with moderate acne, while the g/g genotype was more common in patients with severe acne. the a/a variant was protective and associated with a reduced risk of acne (33,34). in china, the cyp17-34t/c polymorphism was associated with acne, with men with the homozygous c/c variant and the c allele having a high risk of severe acne, in contrast to women with mild to moderate acne, where no such association was observed (35 ,36). a polymerase chain reaction (pcr) study examined the effect of cyp17 gene polymorphisms on the development of acne in chinese men. the homozygous c/c variant and the c allele were found to be significantly more common in men with severe forms of acne compared to the control group, confirming statistically significant differences. however, among women with mild and moderate forms of acne, no statistically significant differences were found with the control group, indicating a possible sex difference in the genetic predisposition to severe forms of acne. another study among indonesian patients showed https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 07-2024 37 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 07 pages: 33-48 oclc – 1121105677 publisher: oscar publishing services servi that polymorphisms in the cyp17a1, cyp1a1 and tnf-α genes did not correlate with the risk of developing severe acne. however, it has been found that polymorphisms in the cyp1a1 gene may contribute to acne in general. these findings highlight the complexity of the genetic background of acne and the need for further research to determine the precise role of these and other genetic factors in the development of the disease (37). researchers in germany found that having the gg genotype of the cyp1a1 gene may increase the risk of developing acne. this genotype is thought to contribute to a deficiency of natural retinoids leading to follicular hyperkeratosis and acne vulgaris. this may also explain the high effectiveness of retinoids in the treatment of severe acne in patients with this polymorphism, since they show a better therapeutic response than patients without this polymorphism (38). studies have shown that the -308 g/a and -238 g/a polymorphisms in the tnf gene are significantly more common in patients with acne vulgaris, especially those suffering from severe forms of acne, than in healthy individuals. this is confirmed by the increased risk of developing acne in the european population compared to the asian population. in addition, high levels of the proinflammatory cytokine il-8 and a significant frequency of the il-8-251t>a polymorphism are found in pakistani patients with acne, highlighting a genetic predisposition to the development and severity of acne (39,40,41,42). in addition, analysis of the rs4646421 polymorphism of the cyp1a1 gene showed that although the activity of the cytochrome cyp1a1 enzyme is important for the metabolism of sex hormones and vitamin a, a direct connection of this polymorphism with the development of acne was not found. however, this genetic marker has been shown to have significant prognostic value for predicting severe acne, as patients with severe acne are more than twice as likely to have an unfavorable allelic variant as controls (43). an increase in the level of tspo in the skin of patients with acne, along with other enzymes that metabolize steroids 3βhsd, cyp11a1, may indicate an intensification of the synthesis of steroids in the skin during this period. pathology, as well as their contribution to the development of chronic inflammation in acne (50). a study from western iran found that the pparγ pro12ala and c161t polymorphisms do not directly influence the risk of developing acne vulgaris (av), but the pparγ pro allele is associated with increased susceptibility to av in adults over 20 years of age. in addition, polymorphisms influence the lipid profile of patients, indicating significantly higher levels of total cholesterol and triglycerides in carriers of the variant cg genotype compared to the cc genotype. the study also found that ct and tt genotypes were associated with lower serum cholesterol and ldl-c levels. these https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 07-2024 38 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 07 pages: 33-48 oclc – 1121105677 publisher: oscar publishing services servi data highlight the importance of genetic factors in the pathogenesis and clinical presentation of acne, as well as their possible influence on the lipid profile, which may have implications for the choice of acne treatment strategy (16). a study conducted among turkish patients with acne vulgaris found significant differences in the frequency of the igf-i (ca)19 genotype between affected and healthy subjects, supporting its possible influence on the development of acne (p=0.0002). this genotype was also found to be associated with acne severity (p=0.015), suggesting a role in disease progression in this ethnic group (44,45). studies have also shown that tumor necrosis factor alpha (tnf-α), a powerful pro-inflammatory cytokine, plays a key role in triggering and regulating the cytokine cascade in inflammation and the immune response. one of the functional polymorphic loci, g308a, has a significant effect on the synthesis and level of tnf-α in the body, which emphasizes its potential importance in the pathogenesis of acne and its clinical course (46,47). the authors concluded that elevated levels of interleukin-8 and its genetic polymorphism il-8-251t>a may contribute to the development of acne in the population. genetic markers play a key role in the development and progression of acne. a detailed study of the genetic and immunogenetic factors associated with acne may lead to a better understanding of the molecular and genetic mechanisms of this condition. this knowledge will help in the development of new methods to predict the course of the disease and effective therapeutic approaches to treat acne, taking into account genetic polymorphisms (48,49). the formation of scar tissue includes three phases that follow in a certain time sequence: inflammatory, proliferative and remodeling phase (51). the main structural units active in the inflammatory and proliferative phase are fibroblasts, capillary endothelium, transform-transient growth factor (tgf) β1 and β2, platelet-derived growth factor (pdgf), insulin-like growth factor (igf-1) and epidermal growth factor (egf). vascular endothelial growth factor (vegf), which is produced by epidermal cells, acts as a positive regulator of angiogenesis. tissue inhibitors of metalloproteinases (timps) are endogenous inhibitors of matrix metalloproteinases (mmps). thus, increased levels of timp are presumably associated with hypertrophic scar formation. tumor necrosis factor α (tnf-α) is an inflammatory cytokine produced by monocytes and macrophages during the inflammatory phase. this cytokine is known to cause collagen degradation and help minimize excessive scarring (52). during the remodeling phase, excess extracellular matrix is degraded and type iii collagen, the immature form of collagen, is replaced by mature type i collagen. tgf-β3 is believed to play a leading role in this process. also, members of the mmp family have a significant effect on the degradation and remodeling of the ecm and mediate the degradation of collagen types i and iii, https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query=

servi reducing inflammation and neutralizing the effects of chemokines (53). decorin is a proteoglycan component of cutaneous connective tissue that binds to type i collagen fibrils and influences tgf-β. by binding and neutralizing tgfβ, decorin reduces the stimulating effect of tgf-β on the synthesis of collagen, fibronectin and glycosaminoglycan. decorin levels are reduced in keloids and hypertrophic scars, and its antifibrotic properties have attracted attention as a possible therapeutic agent (54,55). the role of periosteum (extracellular matrix protein), the level of which is sharply increased in hypertrophic scars and keloids compared to normal tissues, is also actively discussed (56,57). proinflammatory factors such as interleukins il-1α, il1β, il-6, and tumor necrosis factor alpha are upregulated in keloid tissues, suggesting that patients with keloids have increased expression of proinflammatory genes in the skin. this may contribute to chronic inflammation, which, in turn, can cause invasive growth of keloids, although according to the results of a study that was conducted in turkey (90 people in the study group and 30 in the control group), polymorphic variants ants tnf-α (-308 g/a) and il-1β (-511 c/t) were not associated with acne susceptibility, acne scarring, or acne severity (58). increased expression of pro-inflammatory factors means that keloids and hypertrophic scars are a consequence of inflammatory processes in the reticular layer of the dermis. various external and internal stimuli (local, systemic and genetic) after injury can contribute to inflammation. the nature of these irritants most likely determines the characteristics, number, and development of keloids and hypertrophic scars. in england, when studying a small group of patients with keloid scars (including acne), they found that the presence of hladrb5 and hla-drb1*15 was associated with keloid disease (59). a meta-analysis of the association of the arg72pro polymorphism of the p53 gene with keloid scars in the chinese population included the results of 6 studies, which included 359 patients with keloid scars and 493 people. as a control. it was determined that the pro allele of the arg72pro polymorphism of the p53 gene is a risk factor for the development of keloids in the chinese population compared to the arg allele (or = 2.29, 95% ci = 1.45–3.60) (60). a study was conducted in china in which the first stage analyzed 1056 patients with acne and 1056 controls using high-density chips. at the second stage of the study, in an independent cohort (1860 patients and 3660 people in the control group), 101 single nucleotide polymorphisms were tested, of which 3 showed an association: rs747650 of the ddb2 gene and rs1060573 (11p11.2), rs7531806 of the sell gene (1q24.2), which are involved in androgen metabolism, inflammation, and scar formation in severe acne (61). https://doi.org/10.37547/ajbspi/volume03issue03-01

volume 04 issue 07 pages: 33-48 oclc – 1121105677 publisher: oscar publishing services servi keloids develop in fibroproliferative disorders against the background of chronic inflammatory processes in the skin. a genome-wide association study showed an association with rs8032158 in the nedd4 gene. this gene is expressed by neural progenitor cells and has six different transcripts. carriage of the rs8032158 risk allele c in patients with keloids is associated with selectively higher expression of type 3 transcript (tv3 nedd4) and activation of the nf-κb pathway. the analysis revealed that nedd4 tv3 is involved in nf-κb activation through its association with the adapter protein rip. these results suggest that nedd4 tv3 is a potential diagnostic marker and therapeutic target for chronic skin diseases, including keloid (62). a genome-wide association study of 478 african americans (122 cases, 356 controls) was conducted in the usa in 2014. an association was found with the q21.2-22.3 locus on chromosome 15, which includes the nedd4 gene. this gene has previously been shown to be associated with keloid scars in japanese and chinese populations. but in african americans, a more significant association was found with the myo1e gene. in addition, an association was established with the q13.5 locus on chromosome 11 (myo7a gene, rs35641839, or = 4.71, 95% ci 2.38–9.32, p = 8.34 × 10– 6). the authors suggest that the identification of polymorphisms associated with the formation of keloid scars in two myosin genes indicates that the altered cytoskeleton contributes to enhanced migratory and invasive properties of keloid fibroblasts (63). long non-coding rnas (lncrnas) are believed to play a significant role in human diseases. studies have shown that overexpression of long non-coding rna ac067945.2 did not affect cell proliferation in hypertrophied scar tissue, but promoted early apoptosis in normal skin fibroblasts. except moreover, overexpression of ac067945.2 inhibited the expression of col1a1, col1a2, col3a1 and α-sma proteins. in turn, tgf-β1 can inhibit the expression of ac067945.2. in the group with overexpression of ac067945.2, 138 mrna expression differed from the control group, of which it was increased in 14 and decreased in 124. overexpression of ac067945.2 correlated with developmental processes, binding, extracellular region and the vegf and wnt signaling pathways. the study revealed the functions of the novel lncrna ac067945.2, which may help understand the mechanisms regulated by ac067945.2 in the pathogenesis of hypertrophic scars (64). overexpression of long non-coding rna ncrna8975-1 was found in hypertrophic scars and skin fibroblasts. overexpression of lncrna8975-1 prevents cell proliferation and reduces the expression of col1a2, col1a1, col3a1 and α-sma in hypertrophic scar fibroblasts, whereas knockdown of lncrna8975-1 has the opposite effect. further studies of the mechanisms by which lncrna8975-1 expression is regulated may https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 07-2024 41 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 07 pages: 33-48 oclc – 1121105677 publisher: oscar publishing services servi lead to a better understanding of the pathogenesis of hypertrophic scars (65). the study of the genetic aspects of the problem of scar formation after acne, as well as the determination of molecular genetic markers of this condition, is almost at the very initial stage. it is likely that this gap will be filled in the coming years, which will provide impetus for the development of new effective means of preventing and treating this disease (71). regulators of androgen receptors 25-oh-vd, cytochrome p 450 (17alpha hydroxylase), insulin-like growth factor are important in the pathogenesis of rapid non-genomic molecular cellular reactions of peripheral androgen metabolism and, in the future, may determine new algorithms for the diagnosis and treatment of acne diseases (66). an important aspect of acne pathogenesis is the participation of keratinocytes in the inflammatory response. c. acnes activates toll-like receptor (tlr)-2 and tlr-4 on keratinocytes, leading to activation of signaling cascades including the nf-κb pathway and the mapk pathway. subsequently, keratinocytes produce il-1, il-8, il-6, granulocyte-macrophage colony-stimulating factor (gm-csf), tnf-α, matrix metalloproteinases (mmps) and human β-defensin-2 (hbd-2). in addition to tlr-2 and tlr-4, the cd36 receptor expressed on keratinocytes is also involved in the recognition of c. acnes. once c. acnes cd36 is detected, keratinocytes begin to synthesize reactive oxygen species (ros), especially superoxide anion, generated from the cytosolic enzymes nad(p)h oxidases. these ros provide an antibacterial effect and trigger an inflammatory response. analysis of identified variants of the nucleotide sequence of keratinocyte proliferation and differentiation genes showed that severe acne is likely associated with polymorphic loci ap3b1, fermt1, fermt3, gba, sufu (67). data on the role of family history and possible inheritance of acne have been confirmed in a number of studies on familial cases of this dermatosis, its more frequent development in monozygotic twins, but the significance of genetic associations is not fully known. thus, he l. et al. (2014) revealed a connection between acne and tp63, which ensures the regulation and differentiation of epithelial stem cells (68). in another study, the authors suggested an association of acne development with lgr6, which is a mediator of the wnt signaling pathway and ensures the functioning and differentiation of sebaceous gland stem cells. additional associated genes were lamc2, encoding a major component of the basement membrane, and specc1l, encoding a cross-linking cytoskeletal protein that plays an important role in cell adhesion and migration (69). it has been shown that the presence of the disease in first-degree relatives may be a risk factor for the development of dermatosis. a case of identification and determination of the significance of polymorphism of the ncf1, cd3e, orai1, ighm, taz genes in patients https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 07-2024 42 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 07 pages: 33-48 oclc – 1121105677 publisher: oscar publishing services servi with severe forms of the disease with a family history is presented. the conducted studies revealed identical allelic variants in five genes: ncf1, cd3e, orai1, ighm, taz in two closely related patients (father and son) with severe acne. polymorphisms of the studied genes probably influence the development of an imbalance in the oxidase system, the functioning of mitochondria, reduced proliferation of t cells, as well as the formation of an imbalance in the secretion of immunoglobulins. the data obtained may be factors in the torpid course of severe dermatosis, which determines the need for further research (70). based on the analysis of literature data, it can be noted that in our republic of uzbekistan, the prognostic values, features and role of the nlr and tlr2 genes, and their relationship in the development of acne have not been fully studied. references 1. s. a. davis, l. f. sandoval, c. j. gustafson, s. r. feldman, k. m. cordoro treatment of acne in adolescents in the united states: analysis of nationally representative data.pediatrician dermatol, 30 (6) (2013), p. 689-694 view at publisher, r. 2. ashton, m. weinstein acne vulgaris in children pediatr rev, 40 (11) (2019), pp. 577 – 589, 3. k. schnopp, m. mempe. acne vulgaris in children and adolescents minerva pediatrician, 63 (2011), p. 293-304, 4. a.u. tan, b.j. schlosser, a.s. paller review of diagnosis and treatment of acne in adult female patients int j women dermatol, 4 (2) (2018), pp. 56-71. 5. a. l. chien, j. qi, b. rainer, d. l. sachs, y. r. helfrich acne treatment during pregnancy.j am board fam med, 29 (2) (2016), p. 254-262. 6. h. berendes, r.a. bridges, r.a. good fatal granulomatosis of childhood: clinical study of a new syndrome minn med, 40 (5) (1957), p. 309312 view in scopus google scholar, 7. c. guo, x. chen, j. wang, etc. clinical manifestations and genetic analysis of 4 children with chronic granulomatous disease medicine, 99 (23) (2020), pp. view at publisher view in scopus google scholar 162.523, 8. r. lacerda-pontes, l. n. gomes, r. s. albuquerque, p. v. soeiro-pereira, a. condinoneto expanded understanding of chronic granulomatous disease curr opin pediatr, 31 (6) (2019), p. 869-873,10.1097/view at publisher 9. j. au, f. t. gibson, i. k. aronson triad of follicular occlusion: isotope response or side effect of rituximab? dermatol online j, 26 (2) (2020) 13030/qt0wr0k6fx. published february 15, 2020 google scholar 217.295, 10. zn chicarilli triad of follicular occlusion: hidradenitis suppurativa, acne conglobata and dissecting cellulitis of the scalp ann plast surg, 18(3) (1987), p. 230-237,10.1097/00000637https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 07-2024 43 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 07 pages: 33-48 oclc – 1121105677 publisher: oscar publishing services servi 198703000-00009 finding pdf... view in scopus google scholar 218.296, 11. v. vasanth, b.s. chandrashekar tetrad of follicular occlusion indian dermatol online j, 5 (4) (2014), pp. 491-493,10.4103/22295178.142517 12. vasam m., korutla s., bohara r. a. acne vulgaris: a review of the pathophysiology, treatment, and recent nanotechnology based advances //biochemistry and biophysics reports. – 2023. – т. 36. – с. 101578 13. lichtenberger r. et al. genetic architecture of acne vulgaris //journal of the european academy of dermatology and venereology. – 2017. – т. 31. – №. 12. – с. 1978-1990, 14. evans d. m. et al. teenage acne is influenced by genetic factors //british journal of dermatology. – 2005. – т. 152. – №. 3. – с. 579581., heran, maria i. and iwao ando.

publisher: oscar publishing services servi allergic diseases (ad) are one of the most urgent problems of modern medicine. this is due to the high level of their prevalence, the ongoing growth of severe clinical manifestations, which often cause a deterioration in the quality of life, disability, and in some cases deaths among the population [1] the most serious allergic disease is bronchial asthma (ba), which is currently considered as not only a medical but also a social problem [5]. all over the world, including in uzbekistan, there is a tendency to increase the incidence of bronchial asthma and its more severe course. epidemiological studies indicate that in different regions of the world bronchial asthma affects from 4 to 8.2% of the population [1,4]. at the same time, in the adult population, the frequency of bronchial asthma varies within 5%, and in the children's population it increases to 5-12% [2]. introduction: the study of the prevalence and risk factors for the development of the incidence of bronchial asthma in children and adults in the bukhara region. methods a descriptive ecological epidemiological study was carried out. according to the statistical

servi almost 3 times higher than official statistics (average 2.3%) (2). the study of the distribution of indicators of the incidence of bronchial asthma in the bukhara region revealed that the areas of risk for this pathology are areas with industrial zones: karakul, karulbazar and the city of kagan. the risk groups for the incidence of bronchial asthma are children under 9 years of age and adults aged 60 years and older. the prevalence of bronchial asthma ranges from 5.5 per 1,000 population in relatively clean areas of residence to 33.5 per 1,000 population in industrialized areas. the researchers, having analyzed the case histories of patients with bronchial asthma, found that at the time of admission to the hospital, 72.1% of the inhabitants of the industrial territory of karakul had 5 or more asthma attacks, while in relatively clean areas (in the control group) 56% (p < 0 .05). in addition, 21 the conjugated analysis of hygienic indicators characterizing the state of the habitat, and indicators of the health of the population, performed on the territory of the korakul district, made it possible to assess the contribution of the technogenic load to the formation of environmentally caused diseases. the incidence of bronchial asthma in children was statistically significantly higher in areas with a high level of air pollution (p<0.05). indeed, the long stay of children in the home, the use of modern finishing materials, heating, humidification and ventilation technologies in residential buildings have changed indoor air quality and increased its impact on the respiratory system. living in dusty, poorly ventilated, damp rooms, keeping and breeding various animals and birds at home significantly affect the incidence of bronchial asthma. in addition, cigarette smoking, including the passive form, increases the risk of developing and aggravates the course of bronchial asthma. bronchial asthma can occur at any age. approximately half of the patients develop the disease in the first 10 years of life, another third up to 40 years. the results of this study showed that the risk groups for the incidence of bronchial asthma in the districts of the bukhara region are children in the age groups of 3–4, 5–6 and 7–9 years, which is consistent with the data of a study performed in the tashkent region, where the highest prevalence of bronchial asthma occurs at the age of 5 up to 9 years [1]. at the same time, the authors note the highest rate of new cases of bronchial asthma among children aged 2 to 4 years in girls and from 1 to 4 years in boys. apparently, this age is critical for the clinical manifestation of the disease. in this regard, the development of bronchial asthma in children, as an environmentally determined disease, is genetically determined and depends on the genetic characteristics of the organism, which determine the formation of the disease only in hereditarily predisposed individuals. 5-6 and 7-9 years old,

structure of the adult population with that of the entire adult population revealed the highest incidence of the disease in the population of 60 years and older (see table 2). similar results were obtained in tashkent, where the highest prevalence of bronchial asthma among the adult population falls on the age group of 60–69 years (1.24–1.26%) [2]. gerontological features of the incidence of asthma in the literature are poorly reflected and studied, since it is believed that the occurrence of a primary incidence of bronchial asthma in the elderly is a rare phenomenon. in accordance with the models of the development of diseases, it can be assumed that the occurrence of bronchial asthma in the older population occurs according to accumulation or ontogenetic mechanisms. conclusion thus, the study showed that the highest incidence of general morbidity with bronchial asthma in children and adults is observed in the city of kagan with the operation of an oil extraction plant, in the karaulbazar district with an oil refinery and in the karakul district with a kandim gas processing plant. an increased risk of primary incidence of bronchial asthma exists for children aged 3 to 9 years and for adults 60 years of age and older. pollutants, in particular chemical impurities, contained in the emissions of industrial enterprises karaulbazar and karakul, being a component of a sufficient cause, contribute to an increase in the frequency of seeking medical help for bronchial asthma. references 1. asher mi, keil u., anderson hr et al. international study of asthma and

the results in the context of existing literature on metal exposure and cataract development. discuss the potential implications of metal accumulation in serum on cataract etiology, considering oxidative stress and lens opacification mechanisms. by systematically following these methodological steps, this study aims to provide valuable insights into the role of metals in cataract development by analyzing serum metal concentrations in cataract patients. the integration of metal analysis and cataract assessment offers a unique perspective on potential environmental factors contributing to this age-related ocular disorder. results the study explored the relationship between serum metal concentrations and cataract severity in a cohort of cataract patients. advanced analytical techniques revealed varying metal profiles in serum samples collected from participants across different stages of cataract severity. analysis indicated that certain metals, such as lead and cadmium, exhibited higher concentrations in participants with more advanced cataracts, while levels of other metals like zinc and selenium showed different patterns. correlation analyses further illuminated potential associations between specific metals and cataract severity. discussion the discussion centered on the implications of the observed associations between serum metal concentrations and cataract severity. elevated levels of metals such as lead and cadmium in cataract patients with advanced lens opacities suggest a potential role for metal exposure in cataract development. these metals are known to induce oxidative stress and promote lens opacification. the study findings align with the emerging understanding that environmental factors, including metal accumulation, can contribute to the multifactorial etiology of cataract. the discussion also acknowledged the complex interplay of genetic susceptibility, age-related changes, and environmental factors in cataract formation. metals present in serum may originate from various sources, including diet, occupational exposure, and environmental pollution. therefore, the metal profiles observed in serum might reflect a cumulative effect of multiple exposure pathways. conclusion in conclusion, this study sheds light on the potential role of serum metal concentrations in cataract severity, contributing to our understanding of the interplay between environmental factors and cataract development. the correlation between certain metals and advanced cataracts underscores the importance of investigating the impact of metal exposure on ocular health. while the study highlights associations, https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

great and diverse in all periods of a person's life, including intrauterine [1]. they regulate and coordinate the development of the fetus, the processes of growth and differentiation of tissues, especially the nervous one [3]. thyroid hormones affect almost all metabolic processes, determine postnatal growth, psychomotor, physical and intellectual development [2,4]. the functioning of many organs and systems largely depends on how fully the child's needs for thyroid hormones are met [3]. an actively functioning thyroid system determines the level of the child's general health [5]. a complex of unfavorable factors, including, first of all, a complicated course of pregnancy, childbirth, diseases of newborns lead to a violation of the postnatal adaptation of the pituitary-thyroid system of newborns, which manifests itself in the form of a transient increase in the level of thyroid-stimulating hormone during the first month of life and is defined as neonatal transient hypothyroidism [3,7]. the course of pregnancy in women with various pathologies of the thyroid gland may be accompanied by intrauterine growth retardation, low birth weight, and antenatal death [6]. however, according to the literature, we did not find information about the anatomometric features of the fetus at different stages of pregnancy in women in a state of thyroid insufficiency. an indepth study of this issue will make it possible to develop recommendations for a rational assessment of fetal development in this category of pregnant women. the aim of our study was to study the anthropometric parameters of the fetus in healthy and pregnant women in condition of hypothyroidism. materials and research methods mandatory screening tests in the i, ii and iii trimesters are performed in accordance with the order of the ministry of health of uzbekistan of june 2018, po 5590 “on improving prenatal diagnostics in the prevention of hereditary and congenital diseases in children.” fetometry data of 25 healthy fetuses and 32 fetuses in condition of hypothyroidism were determined. screening studies were conducted according to the standard at a certain time: the first screening at 12-13 weeks, the second screening at 22-23 weeks, and screening in 22-23 weeks. the average age of pregnant women in both groups averaged 33 ± 0.4 years, all pregnant women had singleton pregnancies. examination of pregnant women includes a mandatory three-time screening ultrasound examination: in 10-14 weeks of pregnancy, when the thickness of the collar space of the fetus is mainly assessed; in 20-24 weeks, ultrasound is performed to identify malformations and echographic markers of chromosomal diseases; ultrasound examination in 32 34 weeks is carried out in order to identify malformations with their late manifestation, as well as for the purpose of functional assessment of the state of the fetus. the main purpose of these studies is to assess the capabilities of the fetoplacental system in terms of providing appropriate conditions for the development of pregnancy and its successful completion. main part the results of the study showed that the biparietal head diameter in fetuses of healthy pregnant women at the stages of the first screening examination in 12-13 weeks averaged 22.2 ± 1.3 mm, in fetuses of pregnant women in a state of hypothyroidism at the

down by 2 times. at the same time, indicators of biparietal head diameter in healthy pregnant women increased by 23.9%, parameters of frontal occipital head size by 21.6%, head circumference by 34.8%. these indicators in fetuses of pregnant women in a state of hypothyroidism had similar values to those in fetuses of healthy pregnant women, the biparietal diameter increased by 26.9%, the frontal-occipital size by 24.3%, the head circumference by 26.4%. in the periods between the second and third screening examinations (26-30 weeks), the intensity of the growth of the head size in fetuses increased more intensively in pregnant fetuses in a state of hypothyroidism. analysis of the data shows that the rate of increase in biparietal head diameteres in fetuses of healthy pregnant women was 18.7%, frontal occipital size by 23.6%, head circumference by 14.8%. in fetuses of pregnant women in a state of hypothyroidism, these indicators were 19.4%, 17.7%, 21.3%. the smallest growth rate of fetometry indicators was noted during the third screening examination. the biparietal diameter in fetuses of healthy pregnant women increased by 3.1%, the frontal occipital size by 5.7%, and the head circumference by 14.8%. in fetuses of pregnant women in a state of hypothyroidism, these indicators were 3.4%; 7% vs. 16%. the growth rate of fetometry values in 12 to 35 weeks in fetuses of healthy pregnant women increased biparietal head diameter by 292.7%, frontal occipital size by 297.8%, and head circumference by 313.7%. in fetuses of pregnant women in a state of hypothyroidism, during the studied period, the growth rate of head parameters increased biparietal diameter by 296%, frontal occipital size by 295.6%, head circumference by 302.8%, conclusion thus, it can be concluded that in fetuses of pregnant women in a state of hypothyroidism, the biparite and frontal occipital head sizes are significantly smaller at the stage of the second screening examination than in fetuses of healthy pregnant women. the head circumference of the fetuses of pregnant women in a state of hypothyroidism at all stages is less than that of the fetuses of healthy pregnant women.

to evaluate the shear bond strength of composite resin to dentin after rewetting with a desensitizer. the study involved 60 extracted human molars, which were randomly divided into three groups: group a (control) without desensitizer treatment, group b with desensitizer treatment followed by rewetting, and group c with desensitizer treatment without rewetting. the dentin surfaces were prepared and treated according to the assigned group. composite resin cylinders were bonded to the dentin surfaces, and shear bond strength testing was performed using a universal testing machine. the results revealed that group b, which underwent desensitizer treatment followed by rewetting, exhibited significantly higher shear bond strength compared to group a (control) and group c (desensitizer treatment without rewetting). these findings suggest that rewetting dentin treated with a desensitizer enhances the shear bond strength of composite resin, potentially improving the long-term success of restorative dental procedures. keywords shear bond strength, composite resin, dentin, desensitizer, rewetting, in-vitro study. introduction research article evaluation of shear bond strength of

dentin is crucial for the success and longevity of restorative dental procedures. dentin desensitizers are commonly used to alleviate tooth sensitivity and improve patient comfort. however, the effect of desensitizer application and subsequent rewetting on the shear bond strength of composite resin to dentin remains uncertain. this in-vitro study aims to evaluate the shear bond strength of composite resin to dentin after rewetting with a desensitizer, providing valuable insights into the potential impact of desensitizer application on the bonding effectiveness. the success of dental restorations relies on the strong and durable bond between the composite resin and the underlying dentin. dentin desensitizers are commonly used to alleviate tooth sensitivity before restorative procedures. however, the effect of desensitizer application and subsequent rewetting on the shear bond strength of composite resin to dentin remains unclear. understanding the impact of these factors is essential for optimizing bonding effectiveness and ensuring the longevity of dental restorations. dentin hypersensitivity affects a significant number of patients and can cause discomfort during daily activities, such as eating and drinking. desensitizers are designed to alleviate this sensitivity by occluding dentinal tubules and reducing the fluid movement within them. these desensitizers often contain hydrophilic components that promote adhesion and sealing of the tubules. while desensitizers have been shown to effectively manage tooth sensitivity, their influence on the shear bond strength of composite resin to dentin has not been extensively studied. furthermore, the effect of rewetting the desensitizer-treated dentin surface on the bonding strength remains unclear. rewetting, which involves moistening the treated surface, may facilitate the penetration and activation of the desensitizer components, potentially enhancing the bonding effectiveness. this in-vitro study aims to evaluate the shear bond strength of composite resin to dentin after rewetting dentin treated with a desensitizer. the study will provide insights into the potential influence of desensitizer application and rewetting on the bonding effectiveness, allowing for better understanding and optimization of restorative dental procedures. by investigating the shear bond strength of composite resin to dentin in the context of desensitizer application and rewetting, this study aims to contribute to the existing knowledge on adhesive dentistry. the findings will provide valuable information for dental practitioners, enabling them to make informed decisions regarding desensitizer use and the subsequent rewetting step. additionally, this study may pave the way for the development of improved

solution to maintain their hydration. the teeth were randomly divided into three groups: group a (control), group b (desensitizer treatment followed by rewetting), and group c (desensitizer treatment without rewetting). the occlusal surfaces of the teeth were ground to expose the dentin, and the dentin surfaces were etched with phosphoric acid for 15 seconds, rinsed, and gently air-dried. in group b, a desensitizer was applied to the dentin surfaces according to the manufacturer's instructions. subsequently, the dentin surfaces were rewetted with distilled water for a specific duration to simulate the conditions encountered during restorative procedures. in group c, the desensitizer was applied to the dentin surfaces without rewetting. after the desensitizer treatment and rewetting (for group b), a bonding agent was applied to the dentin surfaces of all groups according to the manufacturer's instructions. composite resin cylinders were then placed onto the dentin surfaces using a standardized template and light-cured. the specimens were stored in distilled water at 37°c for 24 hours to ensure complete polymerization. shear bond strength testing was conducted using a universal testing machine at a crosshead speed of 0.5 mm/min until bond failure occurred. the peak load at bond failure was recorded, and shear bond strength values were calculated by dividing the peak load by the bonding surface area. the data obtained were analyzed using appropriate statistical tests to determine any significant differences between the groups. this in-vitro study design allows for controlled testing of the shear bond strength of composite resin to dentin after rewetting with a desensitizer. by comparing the results of the control group and the desensitizer-treated groups, valuable insights can be gained regarding the potential influence of desensitizer application and rewetting on the bonding effectiveness, aiding in the optimization of restorative dental procedures. results the shear bond strength values obtained for each group were as follows: group a (control) had a mean shear bond strength of 23.5 mpa, group b (desensitizer treatment followed by rewetting) had a mean shear bond strength of 29.8 mpa, and group c (desensitizer treatment without rewetting) had a mean shear bond strength of 18.9 mpa. statistical analysis revealed a significant difference in shear bond strength between the groups (p < 0.05). discussion https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

factor (2021: 5. 705) (2022: 5. 705) (2023: 6.534) oclc – 1121105677 publisher: oscar publishing services servi the findings of this study indicate that rewetting dentin treated with a desensitizer significantly enhances the shear bond strength of composite resin compared to both the control group (group a) and the group treated with the desensitizer without rewetting (group c). this suggests that the rewetting process plays a crucial role in improving the bonding effectiveness of composite resin to dentin following desensitizer treatment. the desensitizer used in this study is known to contain components that help seal dentinal tubules and reduce hypersensitivity. it is possible that the rewetting process aids in the penetration and activation of these components, leading to a more effective sealing of the dentinal tubules and improved bonding strength. the rewetting may also contribute to the removal of any residual desensitizer remnants, allowing for better adhesion between the composite resin and dentin. the higher shear bond strength observed in group b could have significant clinical implications. improved bond strength ensures better retention of composite restorations and reduces the risk of restoration failure or debonding. this is particularly relevant in cases where desensitizer application is necessary to manage tooth sensitivity prior to restorative procedures. conclusion based on the results of this in-vitro study, it can be concluded that rewetting dentin treated with a desensitizer significantly enhances the shear bond strength of composite resin compared to both the control group and the group treated with the desensitizer without rewetting. the rewetting process appears to play a crucial role in optimizing the bonding effectiveness of composite resin to dentin following desensitizer treatment. these findings highlight the importance of considering the rewetting step after desensitizer application in restorative dental procedures. by ensuring proper rewetting, clinicians can potentially improve the longterm success and durability of composite restorations. however, further research is warranted to explore the underlying mechanisms and to validate these findings in clinical settings. references 1. mclean de, meyers ej, guillory vl, vandewalle ks. enamel bond strength of new universal adhesive bonding

of soil fertility in early spring. we know that one of the important factors of extracting energy from plants is the exact depth of bending of the egg. in this section, there is some clear information about the exact distribution of the eggs of small-seeded plants. when looking at the opinion of some scientists, it is better to bend the seeds of smallseeded plants, because it reduces the fertility of the eggs, while other scientists said that it is necessary to bend the seeds of small-seeded plants [1:94-b,2: 183184-b, 3 : p. 18-25]. in order to solve this problem, we experimented with field eggs at different depths (0.3 cm, 0.5 cm, 1 cm, 2 cm, 3 cm, and 4 cm). in each case, 100 eggs were counted and bent to 4 m. the received information is presented in table 3.3.1. it can be seen from

bent in this way, lasted for 158 days. such a connection is attractive in the years 2022-2023. it was observed that there is shedding due to bent hairs at the beginning of dalashay eggs. for example, in 2021, the initial yield of field eggs was 40%, in sowing year (2022) 55%, and in harvesting year (2023) 55-60%. when bending methods were used as an example, almost no hair loss was observed. the duration of the next vegetation phases (growing, flowering, fruiting) was almost the same in all variants. in summary, the first year (2021) lasted 102 days, from total flowering to 30 days from total flowering to 26 days from total flowering to fruit ripening. in the second year (2022), the length of the vegetation cycle was 155 days, and it lasted 94 days from the emergence of the dalashay plant

oscar publishing services servi very often one of the etiological causes of the heart disease is the toxic factor. currently different chemical products used in agriculture for the treatment of grape, vegetable and especially cotton fields. most of chemical compounds such as pesticides have adverse effects on the body. at the present time more than 1000 kinds of pesticides are being used around the worldwide and every year their number is increasing. it is well known, that prolonged exposure to even small doses of pesticides on the body increases frequency and enhances diseases of cardiovascular system, myocarditis of various etiologies. therefore, of great interest is the study of pesticide effects on human and animals, in particular on the cardiovascular system. significant relevance is acquired by the problem of pesticide influence on growing young organisms. heart variability is not only general biological interest, but has a curtain significance in the disclosure of physiological processes developing therein, depending on the environmental conditions. the purpose of the study to determine the characteristics of anatomical, microscopic, submicroscopic and morphometric changes of different layers of the heart wall in rats at an early postnatal ontogenesis under the influence of pesticides through breast milk. material and research methods. in total, 205 rat hearts ages a day olds, 6 day olds, 11days olds, 16 days olds and 21days olds were used. the animals were divided into 3 groups. to obtain this goal several series of experiments were conducted. in the first series after the birth of rat pups, to a mother rats were administered pesticide cotoran at a dose 1/100 ld50 intra-gastrically through a catheter. in the first group of female mother rats starting from the day after giving birth cotoran was administered for 5 days, and rat pups died on the 6th day. in the second group cotoran was administered to mother rats after giving birth for the 10 days and the slaughter of animals made on day 11. in the third group cotoran was administered to the mother rats from the first day after giving birth for 15days, and rat pups died at 16days of age. in the fourth group pesticide was administered to mother rats also after giving birth and rat pups died after 21days of age. in the second series, pesticide β-tetramethyl at a dose of 5mdu was administered in the same way to the mother rats, and rat pups died in an analogical experiment days. to the mother rats in the control group, in the morning on empty stomach depending on the term injected 1 ml of distilled water daily. as a probe, for female rats subclavial catheters№1. were used. the animals were anesthetized with either at 1, 6, 11, 16, 21 days after birth. we used a range of methods including: general histological method, organometry, morphometry, ecg of the heart and mathematical modeling and prognosis of toxic myocarditis. after removing the hearts from thorax measurements for the lengths, widths, thicknesses of the rat hearts were conducted. to determine the linear methods calipers with 0.05 mm scales were used. the length of the heart is determined from thee tip to the outermost part of the base of the heart. heart width defined as a distance between the most projecting portions at atriaventricular groove in a direction from left to right. the thickness of the heart is a distance between the most prominent parts on the level of atria-ventricular groove from front to back. heart shape is determined visually. to determine the heart mass and mass of the rat electronic weight is used. histological sections were made in a plane perpendicular to the long axis of the heart. paraffin sections with 8-10mcm thickness, made using a rotary microtones staining with hematoxyllin and eosin by standard methods. collagen fibers in the connective tissue skeleton of the heart walls were detected with hematoxyllin and picrofuchsin by van gieson’s staining method

thoracic cavity and occupies a large area on the left. the absolute heart weight is significantly increased with increasing body mass. weight of a newborn ups is in average 8±0,4 gr, and the absolute heart weight averaged 140±1,7 mgr. the highest rate of weight gain in rats observed at 16 days of age up to 50%, and heart weight at 6days of age growth rate equals to 21%. from newborn to 22 days of old rat weight increased by 3 times, and the heart weight increases by 1.7 times. our data analogic with the data of the authors that the relative weight of human heart and rat hearts are greatest during neonatal age. heart weight of newborn rat pups are 1.75% from body mass. with age, the heart mass is reduced in relation to the body weight and on the 22 day of postnatal ontogenesis it equals to 1.1% (figure1). the results of the study show that the shape and size of the heart during postnatal ontogenesis at different ages is constantly changing. in newborn rat heart length in average is -4.5±0,02mm, width in average is 4,3±0,3mm, anterior posterior size is-3,8 ±0,2mm. since newborn rats all anatomical parameters are almost the same and in most cases the heart shape newborn rats come close to spherical. during the early postnatal ontogenesis growth in length, width and anterior posterior size is irregular. starting from day 6 rat heart length increases more than the width and anterior posterior size and shape of the heart approaches elongated form. the highest growth rate of anatomical parameters observed in rats is at 6 days of age. anterior posterior size of the rat heart increases in 22 days of age, and heart approaches conical shape. body mass, in grams heart mass, in mgs coefficient figure-1. ratio of heart weight to the weight of the rats.

of ventricular and atrial heart walls, in control group animals showed dynamic growth on the thickness of walls for both the left and right atriums and ventricles of the heart at different times of postnatal ontogenesis and it occurs uneven. growth dynamics of the wall thickness for both left and right ventricles of heart at different terms of development depend from the parts of the heart wall. growth rate of the atrial wall thickness greater in rats 6 days of age. ventricular wall thickness mostly increases in rats 6 and 22 days of ages. the thickness of atrial endocardium is greater on the walls of atrium than in the ventricles. the thickness of myocardium and epicardium is greater in the left ventricle on the posterior part. the thickness of the ventricular wall on posterior part increases more than the atrial wall and on the anterior part. the thickness of the epicardium in age aspect compared with other layers varies slightly. microscopic examination can be traced a certain pattern of development and differentiation in the dynamics of early postnatal ontogenesis in the histological structure of the structural elements of the layers of the wall of the atria and ventricles of the heart in intact rats. this provision is the conclusion of the development and differentiation of the structural elements of the atrial wall and ventricular dynamics in early postnatal ontogenesis. in the early period (6 th and 11 th days) study the structural elements of all layers of the heart wall remain undifferentiated, especially in the myocardium, where cellular elements predominate over the myofibrils. the left ventricle distinguish subendocardial, subepicardial and intermediate layers. subendocardial infarction layer is more differentiated than the other layers and is composed of parallel beams cardiomyocytes that are parallel to the endothelium. subepicardial myocardial layer has a loose structure and puchkoobraznoe, cardiomyocytes it arranged randomly and are larger. in individual cardiomyocytes myofibrils thicker in others a vague and vacuolated. the intramural layer left ventricular myocardial muscle cells are arranged perpendicular to the subendocardial layer. the interventricular septum myocardium heart denser, thicker form cardiomyocytes parallel beams. around cardiomyocytes and around the vessels are arranged bundles of collagen and elastin fibers. reticular fibers are arranged between the cardiomyocytes as a winding dark brown fibrous structure that envelop the individual muscle bundles, forming melkopetlistuyu, and around the vessels in the epicardium krupnopetlistuyu network. in the later stages of research, to the 21 th day, the structural elements of all layers of the heart wall is completely formed, gaining their true morphological and functional features. in the wall of the left ventricle of the heart, all three layers are clearly distinguishable as compared with the previous study periods well developed subendocardial layer which is thicker than the other layers. from the endocardial penetrate deep cracks and tebeziya vessels that reach the intramural myocardium layer. this layer of the myocardium loose and consists of multiple individual beams of cardiomyocytes, between which there are enlightened cracks, small vessels and soft connective tissue stroma. intramural myocardial layer is presented in parallel reaching cardiomyocytes myofibrils which significantly prevail over the nuclear structures. subepicardial layer compared to other layers composed of thin and cut transversely cardiomyocytes that exist between arterial and venous vessels. this venous sinus have different shape and size, some of them form large elongated blood lake. in histochemical staining according to the

the stroma infarction the gentle collagen and discontinuous fibers. when painting pas-reaction compared to previous periods of research in the walls of blood vessels, and connective tissue in epicardium defined decrease in pas-positive substance. in the walls of blood vessels increases the amount of elastic fibers. especially thickens subendothelial inner elastic membrane, which is represented by a thick winding material of uneven thickness deep purple color. the muscular and adventitial layers of artery walls elastic fibers is small, and they are presented in the form of bluish shadow structures. the blood vessels of the rat heart are presented by arterioles, capillaries, venules and sinusoids. the myocardial blood vessels are directed along the bundle of cardiomyocytes. around the cardiomyocytes and vessels located bundles of collagen and elastic fibers. parallel arrangement of muscular fibers and capillaries in the myocardium may create conditions for even pressure on the walls of capillaries thus preventing its clamping in systole. there is no significant difference in diameters of the blood vessels walls of a right and left ventricles. arterioles are characterized by thin inner layer, clearly pronounced middle layer, and outer layers. inner layer of arterioles are presented by the nuclei of endothelial cells with round shape. they are located at a slight distance from each other. well pronounced middle layer consist of circular bundles of muscular fibers. they form two layers. the outer layer is formed by loose fibrous tissue and adventitial cells. the inner diameter of arterioles of newborn rats of control group on average varies11.7±0,6mcm, up to the 6th day there is the greatest pace of growth up to 40% in diameter of arterioles, in the next age group there is an insignificant growth rate for inner diameter of arterioles. capillaries have a diameter in average 4.7±0,6microns. capillaries of myocardium consist of 3 layers. the inner layer is formed by endothelial cells. middle layer is from basal membrane and outer layer from elastic membrane. mainly capillaries of myocardium are found in subepicardial layer. in subepicardial layer blood vessels are rare. the wall of the venules is presented by the endothelial cells which are located at a great distance from each other. muscular layer in venules are underdeveloped. venules thickness on average varies 16.7±1,2mcm. in the walls of left ventricles sinusoids are found. the walls of the sinusoids by structure do not differ from the capillaries. by the diameter sinusoids are bigger than capillaries and reach up to 35-42mcm. sinusoids usually are oval or round shape. the study of morphometric data of the left and right atrium and ventricles inexperimental group show that under the exposure to cotoran observed a decrease in all parts of the heart wall. analysis of the table shows that rats 6days of age have decreased thickness down to 10% on the walls of left and right atrium under the exposure to cotoran. the thickness of the left and right ventricles are less in atrium part by 11-13% compared with control group under the exposure to cotoran. on the 11th day there is an 18% decrease of the thickness of the left and right ventricles are less in anterior part by 23% compared with control group under the exposure to cotoran.. the

part by 9% and posterior part by 11% compared with control group under the exposure to cotoran. findings 1. in postnatal ontogenesis changes in heart position of rat pups occur from cranial to caudal direction. the greatest increase in length, width and anterior posterior sizes occur from the moment of birth to 6 days of age, further mostly the length of the heart grows. from birth to 21 days of age, the ratio relative heart weight to the body weight is reduced from 1.75 to1.1.during the postnatal development of rat pups heart position is displaced from cranial to caudal part. comparative changes occur in heart, body mass and in their rate, and also there are changes in the shape of the heart and the development of the chest. 2. traced a definite pattern of development and differentiation in the dynamics of early postnatal ontogenesis in the microscopic structure of the structural elements of the wall layers of the atria and ventricles of the heart in control rat hearts. 3. the toxic effects of pesticides on the heart of rats manifested pathologic-morphologic changes developing in the wall of arterioles and capillaries in the form of disorganization of fibrous structures, the development of proliferative processes of proper cell walls of blood vessels as well as changes in myocardial muscle fibers in the form of protein dystrophy, disintegration of

services servi c3435t polymorphism in the mdr1 gene involves a substitution of cytosine (c) for thymine (t) at position 3435 of the sequence and is associated with changes in p-gp expression and function, potentially affecting its ability to efficiently pump drugs out of cells. variations in p-gp expression or function due to the c3435t polymorphism could potentially influence the metabolism of endogenous substrates or environmental toxins, which could influence cellular processes associated with leukemogenesis. moreover, altered p-gp expression or function due to the c3435t polymorphism may disrupt cellular homeostasis, potentially leading to increased genomic instability or disruption of dna repair mechanisms, which are known to contribute to the development of leukemia [1,2,3,4, 5]. purpose of the study to develop a pcr method to detect the c3435t polymorphism of the mdr1 gene and evaluate its role in the formation of acute and chronic leukemia. materials and methods of research the study included 103 patients suffering from acute leukemia, who were registered at the republican specialized scientific and practical medical center for hematology of the ministry of health of the republic of uzbekistan, and 90 conditionally healthy individuals were selected as a control group, of which 50 people did not have oncohematological diseases or history of thrombosis. results carriers of the c allele showed a significant decrease in the likelihood of developing the disease by 41% (or = 0.59, 95% ci: 0.39-0.89; p = 0.01), while the minor t allele of the mdr1 c3435t gene significantly increased the risk 1.69 times (or = 1.69; 95% ci: 1.13-2.55; p = 0.01). analysis of the c3435t polymorphism showed that the tt genotype increases the risk of the disease by 2.31 times (or = 2.31; 95% ci: 1.09-4.89; p = 0.027), while the cc genotype demonstrates a 44% reduction in risk (or = 0.56, 95% ci: 0.31-1.03, p = 0.06). it is noteworthy that in this study, the tt genotype was found to be a significant risk factor for the development of the disease. in our study, the main group of patients (n=103) was divided into subgroups depending on the acute (first subgroup) or chronic (second subgroup) course of leukemia. regarding the pathogenetic significance of the c3435t polymorphism of the mdr1 gene in the first subgroup, carriers of the c allele had a noticeable reduction in the likelihood of developing the disease by 48% (or = 0.52, 95% ci: 0.32-0.84; p = 0.008). conversely, the minor t allele of the mdr1 c3435t polymorphism significantly increased the risk of the disease by 1.93 times (or = 1.93; 95% ci: 1.19-3.15; p = 0.008), becoming a significant risk factor for the development of acute leukemia in our research. on the other hand, our study did not reveal a statistically significant relationship between the second group (chronic leukemia) and the c3435t polymorphism of the mdr1 gene (χ2<3.85; p>0.05).

accepted standard. if you summarize all the data, you can get a generalized list of types of lesions. 1. pathology of development during teething: anomaly of shape, size. fluorosis (speckled teeth). enamel hypoplasia (developmental disorder). pathology of the structure of teeth of a hereditary nature (odontogenesis, amelodentinogenesis). syphilis (congenital). other developmental pathologies associated with external factors (taking antibiotics, rhesus conflict). 2. pathological changes in the hard tissues of the tooth: complete loss of the tooth. erosion. color change after eruption. hypersensitivity of tissues. 3. changes in the internal structure of the tooth: root fracture. dislocation of the root. fracture of the tooth crown. opening of the pulp. in our country, another classification is more often used, proposed in 1968 by v. k. patrikeev. according to it, non-carious lesions of the teeth are divided into two groups. 4. lesions that occur before eruption: an anomaly of eruption and development. hypoplasia of teeth. hyperplasia. fluorosis. hereditary pathologies. 5. lesions that occur after eruption: erosion. wedgeshaped defect. necrosis of hard tissues. hyperesthesia of teeth. erasure. tooth injury. pigmentation. hypoplasia. this is the name of the pathology of the development of dental tissue during its formation, that is, in children before teething. such a violation is caused by insufficient mineralization of tissues. the main sign is the complete absence of an organ or its abnormally small development. hypoplasia of teeth can be both congenital and develop after the birth of a child. there are several reasons for this: the conflict of rh factors of mother and child, an infectious disease suffered by the mother during pregnancy, infections in the child after birth, severe toxicosis accompanying pregnancy, premature birth, trauma during childbirth, pathology of the child's development after birth, dystrophy, diseases of the gastrointestinal tract, metabolic disorders, developmental disorders brain activity, mechanical damage to the jaw bone. there are two types of hypoplasia – systemic and local. the first is characterized by the defeat of all teeth, low enamel thickness or its absence. yellow spots appear. local is characterized by the defeat of one or two organs. there is a lack of enamel (partial or complete), structural defects of teeth – they can be deformed. such violations cause pain. severe hypoplasia causes increased tooth abrasion, tissue destruction or complete organ loss, and the development of malocclusion. treatment of hypoplasia includes teeth whitening (at an early stage) or filling and prosthetics (with severe disease). at the same time, the enamel is remineralized with medical preparations (for example, calcium gluconate solution). in order to prevent the https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

diet containing vitamins for teeth (d, c, a, b), calcium and fluoride, as well as strict observance of oral hygiene. hyperplasia hyperplasia – non-carious lesions of the teeth associated with excessive formation of tooth tissues. their appearance is caused by an anomaly in the development of epithelial cells, enamel and dentin. it manifests itself in the form of "drops", which are also called "enamel pearls". they can reach 5 mm in diameter. the main area of localization is the neck of the tooth. such a drop consists of tooth enamel, inside there may be dentin or soft connective tissue resembling pulp. there are five types of such formations according to their structure: true-enamel – consist only of enamel, enamel-dentine – the enamel shell contains dentin inside, enamel-dentine drops with pulp – connective tissue is inside, rodriguez-ponti drops – enamel formations in the periodontium between the root and the alveolus, intra–dentine located in the thickness of the dentin. hyperplasia of dental tissues does not manifest itself clinically in any way, it does not cause pain, inflammation or any discomfort. it is only possible to single out an aesthetic factor if the anomaly affects the front teeth. in this case, grinding and leveling of the surface is carried out. in other cases, if nothing bothers the patient, treatment is not carried out. preventive measures are to protect baby teeth from caries, since their destruction can cause disturbances in the development of permanent ones. fluorosis fluorosis occurs during the formation of dental tissue due to increased intake of fluoride into the body. it changes the correct structure of the enamel and causes its external defects – the appearance of spots, stripes, furrows, dark inclusions. in the development of such pathology, not only an overabundance of fluoride plays a role, but also a lack of calcium. in the child's body, fluoride accumulates more and faster than in adults, coming with food and water. there are such forms of fluorosis: dashed – manifested by the appearance of white stripes without a clear contour; spotted – characterized by the presence of yellowish spots with a smooth surface; chalky-speckled – matte or shiny spots having a white, brown or yellow color (can affect all teeth); erosive – multiple erosion of the enamel surface; destructive (a tooth has broken off or completely collapsed) – harmful processes accompanying fluorosis. methods of treatment of fluorosis vary depending on the form of the disease. so, with a spotty form, bleaching and remineralization is carried out, if necessary, grinding of the top layer of enamel. but the erosive form cannot be cured in such ways, it is necessary to restore teeth with veneers or crowns. general

services servi erosion non-carious lesions of the teeth include such damage to the enamel as erosion. its formation leads to discoloration, aesthetic damage to the tooth, as well as increased sensitivity. it is detected by visual inspection. tooth erosion is characterized by progressive destruction of enamel and dentin, the course of the disease is chronic, can take a long time. the cause of the pathology may be mechanical, for example, when using hard brushes or pastes with abrasive particles. also, erosion can be caused by chemical effects on the enamel when eating foods and beverages with high acidity (pickles, marinades, citrus juices and others). production workers associated with the constant inhalation of harmful substances most often suffer from such a lesion of the teeth. the use of certain medications can contribute to the onset of the disease (for example, a large amount of ascorbic acid has a detrimental effect on the enamel). the cause of tooth erosion can also be disorders in the work of the stomach (increased acidity of its environment) or the thyroid gland. it is difficult to identify the disease at an early stage, since it manifests itself only by the loss of shine on a separate small area of the tooth. the further course of the disease leads to a gradual decrease in enamel and dentin. it looks like worn teeth, most often at the base. treatment is based on stopping the destruction of dental tissues. it includes the use of applications containing fluoride and calcium for about 20 days, then the affected area is covered with fluorolac. it is possible to use veneers or crowns to restore an aesthetic appearance. the complex therapy includes calcium and phosphorus preparations, as well as vitamins for teeth. if erosion is not treated, it can cause hyperesthesia of the teeth. hyperesthesia hyperesthesia of teeth is manifested by increased sensitivity of the enamel and in most cases is a concomitant symptom of other non-carious diseases. the prevalence of this pathology is high: about 70% of the population suffer from hyperesthesia, women are more prone to it. the manifestation is a sharp, severe pain that lasts no more than thirty seconds and appears when external factors affect the enamel. hyperesthesia is divided into types according to several criteria: 1. distribution: limited form affects one or more teeth; generalized characterized by sensitivity of all organs. 2. origin: a form of hyperesthesia associated with the loss of dental tissues; not associated with loss, due to the general condition of the body.

surface of the plant leaf as well as the stem [1]. the stoma consists of guard cells surrounding it, which work to close and open the stomata [2]. the stomata regulate the evaporation of the amount of water and the preservation of carbon dioxide by controlling the work of the guard cells [3]. the spread of water evaporation through the stomata depends on the dimensions of the stomata as well as their density, and through the concentration difference between the outer circumference and the inner circumference of the leaf, water is evaporated through the difference in mole fraction of the leaf and the air, and through the change in the conductivity, opening, and density of the stomata, water absorption is regulated, that is, by reducing or increasing the stomata's opening and flow area, thus controlling the spread[4]. the shape and size of the stomata, as well as its number, vary according to the type of plant [5]. it is possible that there is an adaptive relationship with the environmental conditions that surround the plant, through the change that occurs in the growth and opening of the stomata, meaning that the growth and opening of the stomata is adaptive, and this includes the size and shape of the stomata. genetic factors have an effect on the number and density of stomata, as well as their distribution on the surface of the leaf [6]. plants can adaptation to external factors because they are stable, and this adaptation comes from changing the stomata, their function and distribution. in order to obtain an increase in the rate of photosynthesis, the guard cells emit a different environmental signal that must be responded to in order to improve gas exchange in plants. thus, the process of photosynthesis will increase. when climate conditions change, the stomata work to adjust the closure of the stomata.in order to reduce water loss and reduce its absorption carbon dioxide [7]. the concentration of carbon dioxide, as well as the rate of light flow, are two environmental factors that are sensed by guard cells and work to coordinate the opening of stomata [8]. there are previous studies that have confirmed that stomata are sensitive to carbon dioxide through the synthesis of abscisic acid resulting from drought [9]. guard cells work to regulate the opening of the stomata [10]. dicotyledonous and monocotyledonous plants, with the exception of grass plants, have kidneyshaped stomata [11]. as for herbs, they have dumbbellshaped stomata. controlling the opening and closing of the stomata is important to protect plants from excessive water loss as well as a lack of concentration [2]. carbon dioxide: the role of guard cells is significant in protecting the plant from changing environmental conditions, including temperatures, humidity, water shortages, hormones, and sugars [5]. there are channels in the plasma membrane that regulate ions and transporters, as well as pumps found in the guard cells [12].

dumbbell-shaped stomata on the left. forms of stomata in leaves the epidermis of mature leaves generally consists of three types of cells: guard cells, hairs, and pavement cells [13]. stomata are found on both surfaces of the leaf, and their presence may be limited to the upper surface of the leaf [14]. the density of the stomata may be greater on the adaxial surface of the leaf, and this works to prevent water loss [15]. because this surface of the leaf is less exposed to heat, the pattern of stomata in monocot plants is of the regular type [16]. as for dicotyledon plants, the type of stomata is random [9]. the mature stomata are separated from each other by a human cell, and this works to perform the function of the stomata in the best way that the cells need [16]. it ensures that ions and water are exchanged with the surrounding cells [11]. the effect of light on the development of stomata light is considered an important environmental factor as it affects the growth and development of plants. plants need light in order to carry out the process of photosynthesis, as well as to regulate plant growth [17]. photoreceptors control photosynthesis and development through light [18]. phytochromes absorb red light, with wavelengths reaching 600 nanometers [12]. far-red light has wavelengths of up to 730 nanometers [3]. phototropin and cryptochromates mediate the effect of ultraviolet rays, as well as blue light [19]. an increase in light intensity leads to an increase in the number of stomata, while an increase in light intensity does not affect the area of stomata [20]. regulating the opening of stomata according to their response to light is very important for crop production [8]. the change in the voltage of the plasma membrane that results from light has been observed, and this works to change the transport of potassium through the plasma membrane located in the stomata guard cells on the surface of the leaves. both blue and redlight work on stimulating the opening of the stomata https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 08-2024 26 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 08 pages: 23-31 oclc – 1121105677 publisher: oscar publishing services servi through two paths [21]. red light stimulates the opening of the stomata through photosynthesis, specifically in the middle layer, as well as the chloroplasts present in the guard cells [20]. this leads to reducing the concentration of carbon dioxide present between the cells. that is, red light acts as a signal as well as a source of energy [6]. the response of the guard cells to the rate of decrease in carbon dioxide present between the cells and the direct response of the plastids present in the guard cells results in the opening of stomata resulting from red light [13]. the response to blue light of the guard cells is considered independent of the process of photosynthesis [22]. changes in the light spectrum affect the behavior of the gap, and this change is considered a result of the daily change in the light spectrum, as well as the shading of trees or leaves at sunrise or sunset [17]. the sun is near the horizon or below the horizon, and this leads to a smaller solar angle, and thus the rays travel a greater distance through air [15]. the effect of the concentration of carbon dioxide on the opening of stomata plants work to coordinate the flow of carbon dioxide in order to complete the process of photosynthesis [23]. this is accompanied by a loss of water vapor through the pores in the stomata [21]. when there is an increase in the level of concentration of carbon dioxide present in the atmosphere, the stomata it will close, and this affects the growth of the plant and the temperature of the leaf, as well as the efficiency of water absorption [24]. that is, the concentration of carbon dioxide affects the opening of the stomata, and it also works to regulate its growth through the stomata [12]. approximately 40% of carbon dioxide enters the leaves of plants during one year [25]. it is affected the process of photosynthesis changes the stomatal indicator that occurs in response to carbon dioxide in the atmosphere, and this works to change the concentration of carbon dioxide in the atmosphere [26]. the reason for global warming is the continuous increase in the concentration of carbon dioxide in the atmosphere, and this increase affects the development of terrestrial plants [27]. when the concentration of carbon dioxide continues, it leads to a negative effect on the development of stomata in the leaves [28]. that is, the relationship is inverse between the increase in the concentration of carbon dioxide and the development of stomata [29]. the greater the concentration of carbon dioxide, the greater the decrease in the stomatal index. that is, the response of plants to changes in the concentration of carbon dioxide [30]. the greater the flow of carbon dioxide. water and materials are transferred to the guard cells that surround the pores of the stomata. the opening of the stoma is regulated [22]. the dissolved potassium works to regulate the closing of the stoma [31]. this is done through the guard cells that work on the flow of materials and water. the guard cells work to control the movement of the stomata [32]. the increase in the https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi concentration of carbon dioxide and abscisic acid work. on closing the stomata, through studies, it has been found that there is a convergence between the pathway of carbon dioxide and abscisic acid, and that as the concentration of carbon dioxide increases, it stimulates an increase in the concentration of abscisic acid present in the guarding cells of the stomata, and thus leads to the closure of the stomata [33]. stomata and temperature: stomata are affected by high temperature, as temperatures lead to the development of stomata and their opening, and high temperatures will lead to preventing the production of stomata [34]. that is, high temperatures pose a danger to the plant because they cause water shortages and thermal damage [35]. plants take several mechanisms to reduce the effect. high temperatures until the leaves take the form of elongating their petioles, which works to cool the plant [36]. the process of transpiration also works to cool the leaves. the fewer the number of stomata, the more this indicates a response to high temperatures, which leads to a decrease in cooling of the plant. plants coordinate the process of cooling the leaves through the process of transpiration in return [37]. it loses its response to elongation, meaning that high temperature and the density of stomata are two factors that control the coordination of the plant’s response [38]. high temperature affects the process of photosynthesis, as the rubisco (ribulose-1,5bisphosphate carboxylase /oxygenase) enzyme has an important role in the process of photosynthesis [39]. also, this enzyme is sensitive to high temperatures, and the more this enzyme is affected by temperature, the more it has a negative effect [40]. on the activity of the krebs cycle, 1-it works more quickly to stop the action of the rubisco enzyme, which is active. 2it reactivates it more slowly, through the enzyme, which is sensitive to high temperatures. high temperatures stimulate the opening of the stomata, and this leads to coordination between the cooling of the leaves and the activity of using them [41]. water for the movement of guard cells caused by high temperatures, components that work to open stomata through blue light [42]. humidity and stomatal development humidity has a close relationship with temperature because during the saturation process it will increase as the surrounding air temperature rises, and this affects the stomata, as they close in response to this deficit in vapor pressure, that is, less humidity, and this has an important role in the ability of plants to control water loss when the environmental conditions surrounding the plant are dry, as the stomata are closed to prevent the plant from drying out. when plants are affected by moisture, it has the ability to close the stomata. it also has an effect on the density and size of the stomata [43]. the stomata are sensitive to air humidity, as they have a high response to humidity, as high relative humidity increases the size of the stomata, and this it leads to the expansion of

science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 08 pages: 23-31 oclc – 1121105677 publisher: oscar publishing services servi leaves, meaning that the density of stomata will increase in many types of plants due to high humidity [44]. when an imbalance in humidity occurs, it will negatively affect the absorption of carbon dioxide and water loss, leading to the death of the plant [39]. conclusion the stomata have an important role in balancing the water loss of plants with the process of photosynthesis. it is known that the stomata change their pattern according to the environment in which the plants are located. they are considered important organizing centers in the plant leaf and work to increase the absorption of carbon dioxide so that the process of photosynthesis can take place, by opening. when closing the stomata can reduce water loss through the process of transpiration, meaning it is very important for balancing water loss. the process of photosynthesis stimulates the opening of the stomata through light, especially red and blue, which work to open the stomata, while high temperatures prevent the growth and development of the stomata. as for humidity, it is an environmental factor that affects when it decreases, the stomata close, and the higher the carbon dioxide concentration, the more this leads to the closure of the stomata, because the relationship between the stomata and the carbon dioxide concentration is inverse. references 1than, x-h, matsui, t., li, s. h, and lin, j. c.

(90% have type 2 diameters mellitus-t2jm). among patients with t2d m, cardiovascular embarrassment are the leading cause of morbidity and mortality, and kidney embarrassment are highly prevalent in patients. management strategies including lifestyle modifications, social support and ensuring medication adherence are key to reducing the incidence of diameters mellitus embarrassment. by making bad lifestyles changes, people can increase risk of developing type 2 diameters. these include an unbalanced diet, lack of activity, lack of sleep, stress, smoking and alcohol. type 2 diameters mellitus is emerging as a replacement clinical problem within pediatric practice. recent reports indicate an increasing prevalence of type 2 jm in children and adolescents around the world in all ethnicities.3embarrassment from diameters mellitus are broadly classified as micro vascular, including neuropathy, nephropathy, and retinopathy, or macro vascular, including cardiovascular and peripheral vascular disease. the risk for developing embarrassment is influenced by many factors including duration of diameters and genetic factors. current treatments have resulted in only a partial reduction in this risk, and the management of those conditions.4patients with diabetic retinopathy are not treated in area of physical medicine. but other embarrassment like circulatory changes, in

country, data on the epidemiology of keratoderma is extremely scarce, which is due to a number of reasons. firstly, the analysis of statistical data and publications in the scientific literature is complicated by the presence of many synonyms for the disease: seborrheic wart, seborrheic keratoma, senile wart, basal cell papilloma, pigmented epithelioma, pigmented papilloma, seborrheic acanthoma, pigmented basal cell epithelioma, senile papilloma, etc. secondly, despite the fact that this benign tumor was first mentioned by s. pollitzer at the end of the 19th century (1890) (1,4,7), its detailed description by d.i. golovin did it relatively recently in 1958 (2,3). and thirdly, to date the etiology of this proliferative process research article morphogenetic characteristics of

volume 04 issue 06 pages: 54-69 oclc – 1121105677 publisher: oscar publishing services servi on the skin is not clear. according to the international histological classification of skin tumors “pathology and genetics of skin tumors”, published under the auspices of the international agency for research on cancer (5,6,7), seborrheic keratosis is a benign epithelial tumor and is a type of acanthoma. the disease affects men and women almost equally, predominantly over 40 years of age (17). a clear correlation of its debut with age has been established. thus, in the cohort of 24–49 year olds, the prevalence of seborrheic keratosis was 38%, in 50–59 year olds – 69%, in 60–69 year olds – 86%, and among 70–79 year olds – more than 90% (34). the disease is extremely common in countries with high levels of insolation, for example, in australia, where it occurs in 100% of cases in the population over 50 years of age. (35). european studies indicate a slightly lower incidence of this epithelial tumor: 82% among men and 62% among women aged over 70 years (8,9,10,37,39). russian researchers point out that closed areas of the skin exposed to mechanical stress (friction, pressure) are most affected. in patients with numerous elements of seborrheic keratosis, a positive family history is often recorded (11,12,13,42,49). seborrheic keratosis is represented by multiple foci of proliferative growth (14,16,21,45). dermatoscopic and histological examination is mandatory to verify the diagnosis (15,16,23,28,29). seborrheic keratosis (sk) is a common benign tumor of the epidermis in men and women, occurring more often after 45-50 years. ks elements appear as distinct brown spots and/or plaques widely distributed along the edges of the skin (17,18,19,25,26). there is no unified morphological classification of this disease, since the histological manifestations of ks are varied symptoms of several histological types may be present in the same lesion (20,25,28,29). in foreign literature they are divided into acanthous, hyperkeratotic, adenoid, irritated, clonal type and melanoacanthomas. the diagnosis of ks in most cases is not in doubt, but the tumor can mimic other skin neoplasms: common warts, lentigines, melanocytic nevi, actinic keratosis, bowen's disease, squamous cell carcinoma both clinically and during pathological examination (21,22,32,38). the etiology of ks is unknown, although genetics, increased sun exposure, somatic mutations in fibroblast growth factor receptor 3 (fgfr3), and human papillomavirus have been identified as risk factors (23,24,31,35). currently, the theory of keratinocyte aging and impaired apoptosis in ks is widely accepted. studies are rare, and the reasons for changes in the proliferative properties of cells in ks are unclear (25,26,27). in addition, mk is of interest for studying cell cycle disorders, since according to modern histological criteria it is classified as a benign tumor (28,29,30). however, many immunohistochemical features of malignant neoplasms and clinical cases of malignant transformation within mc foci make it necessary to continue the targeted study of the pathogenesis of the https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 56 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 54-69 oclc – 1121105677 publisher: oscar publishing services servi neoplasm. the main mechanism of proliferation impairment is a defect in the function of suppressor genes. in addition to high proliferation, tumor growth is associated with impaired cell ability to regulate apoptosis. the most studied cell cycle markers that are involved in the control of the proliferative potential of any cell are p53, p21, p27 and p16. determination of their expression level using immunohistochemical methods allows us to identify the degree of proliferation disorder, which is invariably accompanied by tumor growth, the ability of the tumor to invade and metastasize (10,12,13,14). p27 (kip1) is an inhibitor of cyclin-dependent kinase 1b, a product of the human cdkn1b suppressor gene, a member of the cip/kip protein family. this protein regulates the course of the cell cycle, is responsible for its arrest in the g1 phase by suppressing the activity of the cyclin a/cyclindependent kinase 2 and cyclin e/cyclin-dependent kinase 2 complexes. p27 is a nuclear-cytoplasmic protein, its intracellular localization is regulated posttranslational modifications. it performs its inhibitory functions in the nucleus; after its movement into the cytoplasm, further advancement of the cell through the cycle becomes possible (10,11,15). overexpression of p27 has been studied in malignant neoplasms of internal organs and is an unfavorable prognostic factor for tumor progression (24,27,28). there are few studies on benign neoplasms, and they contain conflicting data. thus, in a study of 10 irritated and acanthotic scs, a. brueks et al. (8) overexpression of only p27 was detected along with the absence of expression of p53, p16 and a low proliferative index, which allowed the authors to talk about the leading role of p27 in the control of cell proliferation. however, it seems to us appropriate to study p27 in all types of ks, taking into account their morphological diversity. as a result of the study, a violation of p27 protein expression was revealed in all histological types of ks, which indicates its significant role in the pathogenesis of the disease. increased expression of p27, normally found in the greatest quantity in cells in the g1 phase (19,20), was found in the authors’ studies in irritable, adenoid and some cases of clonal types. considering that p27 is a “reserve brake” of cell division (12,13), its significant increase in ks may indicate the absence or insufficient response of the first link of cell cycle regulators p53 and p16 to an increase in the proliferative activity of cells. the staining of nuclear membranes and adjacent areas of the cytoplasm was considered as a decrease in the nuclear content of p27 and its release into the cytoplasm. an imbalance between the amounts of nuclear and cytoplasmic p27 is a poor prognostic sign and is found mainly in malignant skin tumors. according to the literature (12,13,40,41,46), more than 70% of metastatic melanomas contain p27 in the cytoplasm, while melanomas without metastases contain p27 in the nucleus. the appearance of a significant number of cells with nuclear membrane staining, predominantly in the irritated and adenoid https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 57 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 54-69 oclc – 1121105677 publisher: oscar publishing services servi type of ks, indicates a greater risk of malignancy than in other histological types of tumors, where there is no membrane staining. a negative reaction during an ihc study or the detection of single positive nuclei of tumor cells in hyperkeratotic, acanthotic and clonal (in some cases) mc can be regarded, on the one hand, as the absence of significant proliferative activity of cells and the lack of inclusion of a “reserve” mechanism" in the form of p27, on the other hand, indicate a defect in apoptosis, given the slow, steady growth of elements. in none of these cases, specific staining of nuclear membranes was detected, which indicates different mechanisms of cell cycle disorders in different histological types of keratomas. thus, morphological variants of mc have different prognosis for development, growth and risk of malignant transformation. the identified features of p27 protein expression indicate the presence of disturbances in the regulation of the cell cycle and proliferative activity of tumor cells, characteristic of each histological type of ks, which must be taken into account in a comprehensive assessment of the expression of other cell cycle markers in ks (13,45). the role of insulin resistance in the pathogenesis of ks brings us closer to the theory of keratinocyte aging. in a study by a. saraiya et al. in 2013, a case was described in which the appearance of multiple mcs in the absence of a genetic predisposition was associated in patients with insulin resistance and type 2 diabetes mellitus (type 2 diabetes). thus, a major role for high insulin concentrations was suggested in stimulating dna synthesis and cell proliferation. also, m. blomberg et al., based on their observations, recommended that when fgfr mutations are found and concomitant skin pathology in the form of papillary pigmentary dystrophy of the skin or multiple mcs, insulin studies are carried out in order to detect hyperinsulinemia 2. it should be taken into account that type 2 diabetes is one of the most common diseases; every 20 inhabitants of the planet suffer from it after 35–40 years. in addition, it is included in the so-called group of “old age” diseases along with ischemic heart disease, stroke, and atherosclerosis. in a study by a number of authors of 150 patients with multiple ks, type 2 diabetes occurred in 65.3% of cases (98 patients), and impaired glucose tolerance – in 24% of cases (36 patients). such a high percentage of a combination of carbohydrate metabolism disorders and multiple ks can hardly be considered a mere coincidence, given that both diseases are genetically determined and develop in middle and old age. interestingly, one of the possible factors in the development of type 2 diabetes is considered to be an increase in the level of p16 in the pancreas during aging, leading to inhibition of beta cell proliferation and a decrease in their ability to respond to damage, which subsequently leads to insulin resistance (50). morphologically, 6 histological types are distinguished: acanthotic, adenoid (reticular), hyperkeratotic (papillomatous), clonal, melanoacanthoma and https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 58 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 54-69 oclc – 1121105677 publisher: oscar publishing services servi irritated. in all histological types, hyperkeratosis, acanthosis, papillomatosis, horny and pseudohorny cysts are present to varying degrees of severity. the intensity of melanin pigment varies from almost completely absent to strong. in addition, 2 rare histological types of seborrheic keratosis have recently been described with a large amount of mucin in the cells adamantinoid and when basaloid keratinocytes are arranged like “pseudorosettes”. currently, there is no consensus on the etiology and pathogenesis of ks. most theories are contradictory and do not explain the essence of the pathological process and the variety of forms. follicular keratoses represent a disorder of keratinization and differentiation of keratinocytes, leading to the formation of keratotic plugs and parakeratotic cones that penetrate the dermis, causing perforation of the epidermis. there is no uniform classification of keratoses pilaris. there are papular, atrophying and vegetative forms (4,29,30). the etiology and pathogenesis have not been fully studied. the previously assumed role of a viral or bacterial infection, a violation of vitamin a metabolism in the development of this dermatosis is only of historical interest. a certain significance in the development of the disease, in addition to impaired carbohydrate metabolism, is attributed to liver damage (chronic hepatitis) with the development of secondary vitamin a deficiency (4.14). a genetic predisposition to the development of kirle disease (kd) has not been conclusively proven, although cases of the disease among relatives in the same family with consanguinity (first-degree relatives) have been described. as originally defined by j. kirle (30), it is a disease in which an atypical clone of keratinocytes penetrates through the epidermis into the dermis. it is believed that the basis of the pathological process is a violation of keratinization, differentiation and keratinization of keratinocytes (formation of dyskeratotic foci and acceleration of the keratinization process). this leads to the formation of keratotic plugs with areas of parakeratosis. keratification begins already at the border of the epidermis and dermis. the rate of differentiation and keratinization exceeds the rate of cell proliferation, therefore the parakeratotic cone partially penetrates deeper into the damaged epidermis and causes its perforation into the dermis (4,5,43,49). there is no uniform classification of keratoses pilaris. among the independent nosological forms, papular, atrophying and vegetative follicular keratoses are distinguished. some authors note the similarity of kirle disease (kd) with lenticular persistent hyperkeratosis of flegel, considering the latter as a variant of kd, although the clinical manifestations differ. other authors (5,7,18) classify cd as vegetative follicular keratoses, and flegel's disease as papular. there is a concept of reactive perforating keratinization disorder in kidney disease, liver disease and diabetes mellitus. the concept of perforating skin

science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 54-69 oclc – 1121105677 publisher: oscar publishing services servi diseases has emerged, in which the elimination of altered skin components occurs through the epidermis (transepidermal elimination). some authors dispute the independence of cd as a nosological entity (45,47). in icd-10, in class xii (diseases of the skin and subcutaneous tissue), cd has a subcategory l87.0 transepidermal perforated changes. pathomorphologically, there are depressions in the epidermis and dilated orifices of hair follicles filled with hyperkeratotic plugs. under the plugs, the growth of the granular layer is pronounced, and in places without hypergranulosis there is parakeratosis, penetrating to the dermis. next, the epidermis becomes thinner and horny masses penetrate into the dermis, and inflammatory infiltrates such as granulomas are formed from lymphocytes, leukocytes, histiocytes and giant cells. death of the sebaceous glands, degeneration of collagen fibers, and hyperelastosis are observed (49). clinically, the onset is gradual, new rashes appear as old ones disappear. characteristic are follicular or parafollicular papules, first the color of healthy skin, then a grayish or brownish-red hue, up to 1 cm in diameter. in the center of the elements there is a horny plug, when removed, a crater-shaped depression is formed. papules tend to grow peripherally and coalesce, forming dry polycyclic plaques covered with scales and crusts. the consistency is dense, the surface is uneven, warty. fresh rashes are accompanied by mild itching (more often in patients with diabetes) or do not bother. old lesions are painful when pressed. localization of rashes extensor surfaces of the limbs, torso, buttocks. koebner phenomenon and secondary infection are possible (30). the mucous membranes are not affected, and rashes on the palms, soles, genitals and mouth are rare. the course of kirle disease (kd) is chronic and relapsing, treatment is difficult, and the prognosis depends on the underlying disease. diagnosis is based on history, clinical and histological picture. differential diagnosis includes devergy's lichen pilaris, darier's follicular dyskeratosis, mibelli's porokeratosis, elastosis perforating creeping, reactive perforating collagenosis and flegel's disease (31,32). flegel's disease, like cd, a rare form of keratosis pilaris, is associated with impaired synthesis of keratin 55k. histologically, thinning of the epidermis, follicular orthokeratosis with parakeratosis, spongiosis and lymphocytic infiltrate in the dermis are revealed. the previously assumed importance of odland bodies in the pathogenesis of dermatosis is now doubtful. unlike cd, this dermatosis appears in adolescence and middle age and is characterized by small horny papules that are not prone to plaque formation (27,29,31,32,33). actinic keratosis is a skin disease characterized by limited, dense hyperkeratotic lesions in areas exposed to solar radiation. the probability of occurrence of squamous cell carcinoma in lesions of actinic keratosis, according to some data, is estimated from 0.85 to 10% per lesion per year [48,49,50]. as a rule, squamous cell carcinoma that develops in areas of actinic keratosis https://doi.org/10.37547/ajbspi/volume03issue03-01

volume 04 issue 06 pages: 54-69 oclc – 1121105677 publisher: oscar publishing services servi has a favorable course, but in rare cases it can metastasize (15,16,17). porokeratosis is a rare group of acquired or hereditary dermatoses characterized by linear or annular plaques with a keratotic border. disseminated superficial actinic porokeratosis (dsap) is a disease characterized by impaired keratinization. disseminated superficial actinic porokeratosis is one of six types of porokeratosis. it has wider participation than most other options. these other variants include linear porokeratosis, mibelli porokeratosis, punctate porokeratosis, palmar and plantar disseminated porokeratosis, and disseminated superficial porokeratosis. other rare variants are ptychotropic porokeratosis, facial porokeratosis, giant porokeratosis, hypertrophic verrucous porokeratosis, reticular porokeratosis, and eruptive pruritic papular porokeratosis. the eruptive form of porokeratosis is associated with malignancy, immunosuppression, and a proinflammatory state. rashes appear all over the body. a feature that is observed in all these variants is the horn-shaped plate. on histology, it appears as a column of parakeratotic cells and is characterized by a raised ridge bordering the porokeratotic lesions. risk factors for porokeratosis include genetics, immunosuppression, and ultraviolet light. lesions in disseminated superficial actinic porokeratosis begin as papules and pink to brown macules with a raised border on exposed skin that may be asymptomatic or mildly itchy. these lesions are considered precancerous. there is a risk of malignant transformation to squamous cell or basal cell carcinoma from 7.5 to 10% (12,22,23) eruptive pruritic papular porokeratosis is a rare subtype of porokeratosis that manifests as an acute exacerbation of an annular papule with a distinct peripheral border of a hyperkeratotic ridge and intense itching. eppp mainly occurs in older east asian men. its etiology and pathogenesis are unknown (24). the development of disseminated superficial porokeratosis is sometimes observed in association with renal transplantation, autoimmune diseases, and various hematologic disorders, suggesting that certain immunosuppression may cause widespread abnormal keratinization. it may also be associated with exacerbation of diabetes mellitus due to the formation of anti-insulin antibodies (32). benign lichenoid keratosis (blk, lplk) is clinically often misdiagnosed as superficial basal cell carcinoma (bcc), especially when it occurs on the trunk. however, regression of the bcc may be associated with lichenoid interface dermatitis, which may be misinterpreted as blk on histopathological sections (48). benign lichenoid keratosis is a skin lesion consisting of a non-pruritic papule or slightly indurated plaque, histologically characterized by a band-shaped inflammatory infiltrate involving the surface of the skin. the authors believe that benign lichenoid keratosis may be a specific disease rather than an inflammatory https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 61 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 54-69 oclc – 1121105677 publisher: oscar publishing services servi stage of regressive solar lentigo, large cell acanthoma, or reticulate seborrheic keratosis (16,17,19). a study of palmoplantar keratoderma in eighty-two cases showed that the cause of palmoplantar keratoderma is twenty different diseases, both hereditary and acquired. the maximum number of cases occurs in the hereditary variety of palmoplantar keratoderma (unna-tost syndrome) (28.05%). while among acquired diseases the leading cause was psoriasis (17.07%). two histopathological types of unna-tost syndrome and their correlation with clinical features have been reported (4,5) keratoderma spinosa is a rare dermatosis consisting of multiple projections located on the palms and soles, with a distinct histopathological feature of a parakeratotic column over a hypogranular epidermis. although there are some hereditary cases, most are acquired. the latter may be idiopathic or associated with neoplasms and chronic systemic diseases (15,25). in some literature sources, keratoderma spinosum is referred to as keratoderma spinosa. this condition is identified under several names, such as “music box spinal keratosis” and “palmoplantar filiform hyperkeratosis,” which creates ambiguity in the diagnostic and histopathological features of the disease. because of its association with cancer, all patients with keratoderma spinosa should undergo baseline cancer screening based on age and then once or twice a year or as symptoms appear (3,4). the incidence of skin malignancies has been increasing over the years (46,47). since 1960, their incidence worldwide has increased annually by 4–8% and amounts to about 3 million newly identified cases per year. one of the most significant etiological factors is considered to be excessive insolation frequent exposure to the sun for a long time and repeated sunburn. in many cases, malignant epithelial skin tumors develop in the setting of preexisting dermatoses such as actinic keratosis and bowen's disease (22). bowen's disease is an intraepidermal form of squamous cell carcinoma (or squamous cell carcinoma in situ) in the form of a single, slowly growing plaque. its development is most often associated with exposure to ultraviolet radiation, less often with skin trauma or contact with arsenic. in this regard, two forms of the disease are considered: one is localized in open areas of the skin (exposed to insolation), and the other is localized in closed areas. the course of bowen's disease is steadily progressive, although in the vast majority of cases it remains cancer in situ throughout the patient's life. invasive squamous cell skin cancer develops against the background of bowen's disease with a frequency of 5% to 11% of cases of long-term existence of the pathology. as long as the disease remains in the intraepidermal stage, metastases do not occur. it is possible to differentiate actinic keratosis and bowen's disease only on the basis of histological examination. thus, with actinic https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 62 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 54-69 oclc – 1121105677 publisher: oscar publishing services servi keratosis, dysplastic changes in the epidermis are observed, which occupy no more than ⅔ of its thickness, sometimes with penetration of epidermal strands into the upper parts of the dermis. however, atypical cells can spread throughout the entire thickness of the epidermis in such cases they are called bowenoid actinic keratosis (22,24). bowen's disease is characterized by a sharp thickening of the epidermis, consisting of enlarged cells, in places piling up on each other, with pronounced polymorphism and polychromasia, with acanthotic growths to the reticular layer of the dermis (23,26). proliferation of atypical keratinocytes, as in bowenoid actinic keratosis, is observed throughout the entire thickness of the epidermis. actinic keratosis with foci of bowenization and bowen's disease are distinguished by dysplastic changes in the keratinocytes of the follicular epithelium a sign inherent in bowen's disease. in addition, with bowenoid actinic keratosis, manifestations of solar elastosis are always observed in the dermis. however, according to some authors, the bowenoid type of solar keratosis is histologically indistinguishable from bowen's disease and at this stage of development is regarded as carcinoma in situ (1,22,6,28). despite the atypia of keratinocytes, characteristic of both actinic keratosis and bowen's disease, there are no signs of true invasion the boundary between the epidermis and dermis remains clear. of particular importance in all cases is the study of the expression of a number of cellular markers involved in the mechanisms of development of malignant skin tumors, such as oncoproteins associated with intercellular adhesion and proliferation. several nuclear and membrane antigens are known, changes in expression of which are due to proliferative activity cells. one of the most studied molecular biomarkers is the indicator of proliferative activity ki-67, whose antibodies react with proliferating cells. if the cell does not proliferate, this interaction does not occur. normally, in healthy epidermis, ki-67 expression is observed only in the basal layer, and the average proliferative index, according to various sources, varies from 0.8 to 11% (24,25,34,35,36). the architectural integrity of the epidermis is ensured by keratins and intercellular adhesion molecules epithelial cadherins. e-cadherin is a calcium-dependent adhesion molecule characteristic of epithelial tissue cells. its long extracellular sections form parallel dimers on the cell surface, which, when in contact with e-cadherin molecules of neighboring keratinocytes, form strong zipper-type bonds. a decrease in intercellular adhesion allows affected cells to split off from normal ones, which leads to destruction of histological structures. normally, in the epidermis, ecadherin is detected in 100% of cells in the form of uniform membrane staining. increased cell proliferative activity and impaired expression of ehttps://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 63 american journal of biomedical

capacity (26,27). data from a number of authors indicate that actinic keratosis, bowenoid actinic keratosis and bowen's disease represent different stages of the development of the same malignant process. the predominance of low proliferative activity, the expression of ki-67 in the lower parts of the epidermis and the preservation of adhesive interactions between cells in actinic keratosis indicate the initial stages of the process and its low invasive potential (22,23). epithelial skin tumors are common human neoplasms, accounting for from 20–24.9 to 55.4–61.7% of calls for skin neoplasms. one of the key factors contributing to the activation of proliferative processes in the skin with the subsequent development of neoplasms of various natures is the infection of skin cells with the human papillomavirus (hpv). certain characteristic hpv fragments suppress the activity of the keratinocyte p53 gene, which leads to uncontrolled proliferation of keratinocytes. the importance of certain types of hpv in the development of a number of skin tumors has been shown (27,47,49). the pcna protein is recognized as a more accurate indicator of proliferation, identifying cells in the process of preparing for division in the s-phase of the cell cycle. the evidence that the s-phase in cells affected by hpv is longer (from 18 to 20 hours) than the s-phase in normal epidermal keratinocytes (16 hours) is confirmed by immunohistochemical studies. seborrheic keratosis is the most common benign skin tumor in different regions of the world (47,49). it is known that the vast majority of proto-oncogenes and tumor suppressors are components of several common signaling pathways that control the cell cycle, apoptosis, genome integrity, morphogenetic reactions and cell differentiation. changes in these signaling pathways ultimately lead to the development of tumors. to date, about a hundred potential oncogenes (cellular and viral) and about two dozen tumor suppressors are known. changes characteristic of predominantly malignant human tumors have been identified, including highly specific anomalies used to make a diagnosis, while almost no attention has been paid to benign formations (16,22). two families of proteins, inhibitors of cyclin-dependent kinases, have been identified: ink4 and cip/kip. the first includes four members, including the tumor suppressors p15ink4b and p16ink4a. ink4 proteins have a fairly narrow specificity: by binding the cyclindependent kinase (cdk) cdk4 and cdk6, they prevent the formation of their complexes with cyclins d. the cip/kip family consists of three members: p21waf1/cip1, p27kip1a and p57kip2. these proteins bind and inhibit already fully formed complexes of cyclin d – cdk4(6), cyclin e – cdk2 and cyclin a – cdk2 [5, 6]. inhibition of the functions of cyclin-dependent kinases leads to hypophosphorylation of the prb protein, which reduces the expression of e2fdependent genes, blocks the transition of the cell from https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 64 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 06 pages: 54-69 oclc – 1121105677 publisher: oscar publishing services servi the g1 phase to the s phase, and controls cell division and proliferation. many sources confirm that disturbances in the g1 phase and g1/s checkpoint lead to uncontrolled tumor growth. thus, it has been experimentally proven that a decrease in p16 protein expression leads to hyperphosphorylation of prb and subsequently leads to activation of the transcription of s-phase-specific genes. the p16 protein was discovered by researchers in 1993 and since its discovery has become one of the most sought-after markers in the field of cancer research [10]. it is encoded by the tumor suppressor gene cdkn2a, located on chromosome 9 (9p21.3). the participation of this gene has been noted in the development of both sporadic and familial forms of melanoma, glioma, lung cancer, t-cell leukemia, and b-cell leukemia. in addition, p16 is currently used as a prognostic biomarker for patients with oropharyngeal squamous cell carcinoma and cervical cancer. the expression of this protein and its role in the pathogenesis of benign skin tumors, in particular seborrheic keratosis, have been little studied (22,24,44,45,49). thus, y. h. wu et al. in 17 cases of seborrheic keratosis with signs of bowenoid transformation, he found increased expression of p16 and p21 in the cells, which is also characteristic of bowen's disease and bowenoid papulosis. they were asked to study p16 in patients with seborrheic keratosis to identify possible malignancy of the elements. other authors s. nakamura et al., having identified in skin samples from ks lesions (including in cultured keratinocytes from patients with ks) a pronounced expression of the p16 protein in all tumor cells, associated this not with the possibility of malignancy, but with a violation of the cell cycle , blocking the entry into the s-phase of cells and their premature aging. in support of this hypothesis, in the 4 studied sc samples, genetic analysis revealed the absence of dna fragmentation in tumor cells, whereas in normal epidermis fragmentation was present in the granular and stratum corneum. this indicates that apoptosis is inhibited in ks. brueks et al., studying 10 cases of seborrheic keratomas of exclusively acanthotic and irritable types, noted an average level of expression of the p16 protein and a pronounced, diffuse expression of another protein, the p27 kinase inhibitor, which, in his opinion, indicates the dominant influence of this protein on cell proliferative activity. like p16, the p27 protein (kip1) regulates the course of the cell cycle and is responsible for its arrest in the g1 phase. it is the product of the human cdkn1b gene (22,43). so, today, ideas about the role of proteins inhibitors of cyclin-dependent kinases in oncogenesis are not entirely clear; the data from most studies are contradictory. the possibility of using them in practice as prognostic biomarkers opens up prospects for an individual approach to the treatment of each patient, understanding the pathogenesis of many both malignant and benign human tumors, which https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue

the relevance and need for their further study. conclusions studying the morphological and genetic different types of keratoses is key for correct diagnosis and choice of treatment. the association between metabolic disorders and skin diseases highlights the need for an integrated approach to the management of patients with chronic diseases, including diabetes mellitus. further research is needed to better understand the pathogenesis and develop effective treatments. references 1. кожные и венерические болезни. справочник. под ред. о.л.иванова. м: медицина 2007; 117—118. 2. родионов а.

structure, ligament laxity, and muscle composition influence injury vulnerabilities among female athletes. knowledge of these biomechanical disparities allows for targeted injury prevention strategies, considering anatomical variations unique to women. energy systems and metabolic specificities fuel utilization and nutritional needs differ across menstrual phases. addressing these variations ensures optimal energy availability during training and competition. integrating nutrition plans attuned to hormonal fluctuations maximizes performance potential while supporting overall health. recovery patterns and training adaptations hormonal influences impact recovery kinetics and physiological adaptations in women athletes. tailoring recovery protocols to align with hormonal phases facilitates effective recuperation, enhancing training adaptations and performance outcomes. optimizing training programs for women developing training programs that consider menstrual cycles, biomechanics, and hormonal influences is paramount. customizing training methodologies ensures efficient skill acquisition, strength development, and performance optimization for female athletes. balancing performance and long-term health striking a balance between performance enhancement and menstrual health is crucial. neglecting menstrual irregularities can lead to long-term health issues. advocating for a holistic approach that nurtures both performance excellence and reproductive health is imperative. embracing women's physiological uniqueness understanding the physiological nuances unique to women in sports training isn't merely beneficial but essential for fostering athletic excellence and preserving overall health. recognizing, embracing, and incorporating these nuances in training methodologies not only elevates performance but also advocates for women's holistic well-being in sports. by acknowledging and integrating these physiological intricacies into sports training, we empower female athletes to reach their full potential, excel in their respective sports, and thrive in a supportive and adaptive training environment that respects their physiological distinctiveness. hormonal fluctuations, particularly those occurring during the menstrual cycle, exert notable effects on training adaptations, recovery processes, and overall performance in female athletes. understanding these influences is crucial for optimizing training regimens and enhancing athletic performance. here's an exploration of how hormonal fluctuations impact training adaptations, recovery, and performance: training adaptations: https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03

oclc – 1121105677 publisher: oscar publishing services servi hormonal phases: the menstrual cycle consists of distinct phases follicular, ovulatory, and luteal phases characterized by varying hormone levels (estrogen, progesterone). hormonal effects on energy levels: hormonal fluctuations affect energy availability and utilization. during the follicular phase (increased estrogen), women may experience enhanced endurance and strength due to higher estrogen levels supporting glycogen utilization. strength and muscle function: research indicates that during the ovulatory phase (peak estrogen), women might exhibit improved muscle function, potentially enhancing strength and power output. injury risks: the fluctuation in hormone levels, especially estrogen, can influence ligament laxity, potentially increasing injury susceptibility, particularly for non-contact injuries like acl tears. recovery processes: recovery patterns: hormonal fluctuations impact recovery kinetics. women might experience increased muscle soreness and delayed recovery during the luteal phase (high progesterone), potentially affecting subsequent training sessions. inflammatory response: hormonal changes influence inflammatory responses, affecting recovery from training-induced muscle damage. progesterone dominance during the luteal phase may heighten inflammatory responses, impacting recovery timelines. performance: endurance and metabolic changes: hormonal variations, especially in estrogen levels, affect substrate utilization. increased estrogen levels might enhance fat oxidation, potentially influencing endurance performance. strength and power: timing training sessions to coincide with hormonal phases may optimize strength and power adaptations, capitalizing on the potential performance advantages offered during specific phases. considerations for training and performance optimization: periodization: adapting training cycles based on hormonal phases may enhance training adaptations. adjusting training intensity and volume to align with hormonal fluctuations can optimize performance outcomes. nutrition and recovery strategies: tailoring nutrition and recovery protocols to support energy availability and mitigate recovery challenges during different menstrual phases can aid in optimizing training adaptations and performance. understanding the influence of hormonal fluctuations on training adaptations, recovery, and performance is critical for coaches, trainers, and female athletes. tailoring training regimens, recovery protocols, and nutrition

services servi designing training programs that align with women's physiology involves a multifaceted approach, integrating considerations for hormonal cycles, biomechanics, and recovery patterns. here are strategies to tailor training programs specifically for women athletes: 1. tracking menstrual cycles and hormonal phases: cycle monitoring: encourage athletes to track their menstrual cycles to identify hormonal phases (follicular, ovulatory, luteal). training emphasis: plan training phases to coincide with hormonal fluctuations. during the follicular phase (higher estrogen), focus on high-intensity training or strength development. in the luteal phase (higher progesterone), prioritize recovery, skill refinement, or lower-intensity sessions. 2. adjusting training intensity and volume: phase-specific adaptations: modify training intensity, volume, and recovery periods based on hormonal phases. consider reducing training loads during the luteal phase to accommodate potential performance fluctuations or recovery challenges. strength and power emphasis: capitalize on peak estrogen levels during the ovulatory phase by incorporating strength and power workouts to leverage potential performance advantages. 3. biomechanical considerations: injury prevention: develop injury prevention strategies based on biomechanical differences unique to female athletes. emphasize neuromuscular training, proprioceptive exercises, and techniques to address joint stability. strength training emphasis: tailor strength training programs considering female biomechanics to optimize muscle recruitment patterns and reduce injury risks. 4. recovery protocols and nutrition: recovery strategies: implement recovery protocols that support hormonal variations. adjust recovery modalities and durations during different menstrual phases to address potential recovery challenges. nutritional support: offer nutritional guidance aligned with hormonal fluctuations. emphasize adequate nutrient intake, especially iron and calcium, to address potential deficiencies during specific menstrual phases. 5. comprehensive approach and individualization: holistic athlete development: foster a holistic approach that considers overall well-being. address mental health, stress management, and sleep quality, recognizing their impact on hormonal balance and performance. individualized plans: recognize individual differences among female athletes. tailor training plans based on individual responses to hormonal fluctuations, performance indicators, and recovery patterns. 6. consistent monitoring and adaptation: regular assessment: continuously monitor performance metrics, recovery status, and athlete feedback to adapt training plans accordingly.

provides excellent results, bypassing the need for regular dilatation and providing natural lubrication [3, 16, 17]. numerous proposed treatment methods, which are even more diverse when taking into account their modifications, reflect the complexity of solving this problem. nevertheless, the relevance of this problem remains, and for gynecologists it will always be an important issue to adequately solve it. conservative and surgical treatment methods have been developed and used for a long time with possible modifications. surgical methods can be divided into traction and transplantation. methods such as vecchietti, abbemcindoe and davydov are considered among the most commonly used and recognized in the world. intestinal vaginoplasty is a well-studied procedure that uses a pedunculated segment of the large or small intestine. this method is often used for vaginal agenesis, male-to-female sex reassignment surgery in cases of lack of phallic skin, and for revision after unsuccessful primary reconstruction. in our study, we describe the use of a pedunculated colon segment for vaginal reconstruction after serious complications of the initial surgery [8, 21, 22]. currently, operations to reconstruct an artificial vagina are becoming increasingly common. however, histological analysis of the morphofunctional changes occurring in the functionally leading tissue of the formed bioprosthesis the intestinal epithelium remains insufficiently studied. clinical specialists are naturally focused on the clinical and functional changes occurring both in the artificial vagina and in the patient as a whole. thus, it is necessary to recognize that these changes are a consequence of reactive compensatory transformations in the mucous membrane, which interacts with an unusual microenvironment. based on clinical biopsy material obtained from 15 to 40 months after surgery, two-phase changes in the epithelium were identified: first, a mosaic loss of microvilli by enterocytes was observed, and then the appearance of signs of transitional cellular metaplasia [18]. additionally, some researchers, based on short-term observations of morphology, identify a period of three years during which the intestinal epithelium fully adapts to new conditions [12, 14]. however, such studies remain isolated, usually lacking theoretical justification and focused on solving specific clinical problems [13]. it was previously discovered that reactive compensatory processes in the mucous membrane of the urinary reservoirs, especially in the epithelium, develop in accordance with well-known classical patterns [4,20]. traditionally, the reactive change process is thought to involve three main phases. the first of them is “emergency mobilization,” characterized by the activation of morphofunctional reserves in response to a sharp change in influencing factors. then comes the “plateau” phase, when the system reaches relative stability at a new level of https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 05-2024 31 american journal of biomedical

services servi functioning. with prolonged exposure to extreme factors, a phase of “failure” or decompensation may occur, characterized by a violation of the structural and functional organization. [15, 19]. it is clear that the duration of these phases depends not only on the characteristics of the influencing factor, but also on the histogenetic properties of the tissue on which it affects. consequently, this also influences the choice of diagnostic and treatment strategies in the follow-up care of these patients after surgery. in addition, it is known that such an adaptation process covers all levels of the structural organization of matter, which are analyzed by a histologist, including subcellular, cellular, cellular-tissue and structural-functional units [4, 15].transformations of the intestinal epithelium in the structure of the artificial vagina have not been fully considered from the point of view of the described general patterns of pathology. the epithelium of the intestinal type interacts with the connective tissue, forming the morphofunctional complex “crypt-villus” in the intestine. this complex is a self-regulating system characterized by constant renewal of enterocytes due to the proliferation of undifferentiated cells in the crypt [2]. in the lower part of the crypts there are intestinal epithelial stem cells that can differentiate into various cell types. this differentiation occurs in several directions, leading to the formation of prismatic enterocytes (villous epithelial cells), goblet exocrine cells, paneth cells (with acidophilic granules) and enteroendocrine cells (gastrointestinal endocrinocytes) [6]. under normal conditions, the cellular components that make up a particular tissue should maintain a standard ratio. this ratio ensures the full functioning of the tissue, including its ability for physiological regeneration and cell renewal [7]. it is assumed that under changed environmental conditions these ratios can change in order to maintain the initial state of the tissue, which indicates their adaptive nature [4]. tissue reactivity is a term that is used to denote the individual ability of tissues to make compensatory-adaptive morphofunctional changes in response to various superphysiological influences [7]. the purpose of the study is to determine the patterns of changes in the cellular renewal of the intestinal epithelium in the vagina formed from the sigmoid colon. materials and methods of research. the material was biopsy samples obtained during vaginoplasty after prolapse in women undergoing surgery to create an artificial vagina. at the same time, material obtained from different patients within a period of 6 months to 10 years after reconstructive surgery was available for study. biopsies were taken from several areas of the artificial vagina, usually from the anterior, left and right walls, as well as from the posterior wall. the obtained samples for histological examination were taken from 38 patients with congenital anomalies of the vagina. these specimens were fixed in 10% neutral formalin for 24–48 hours and subjected to

membrane and glands of the submucosal layer, a histochemical study was performed using alcian blue staining. to identify glycol or aminohydroxyl groups that form dialdehyde, a pir reaction (schiff reagent staining) was performed. in addition, using the pas reaction, it is possible to analyze the accumulation of mucin, glycogen, flu-like lesions, as well as lymphoproliferative processes in neovagina tissue. the results were assessed semiquantitatively (in points). a total of 76 blocks were processed, from which 208 drugs were manufactured and studied. when studying micropreparations, histological and histomorphometric analyzes were performed. histomorphometric analysis was carried out using a scanner on a nanozoomer microscope (ref c1314021.s/n000198/hamamatsu photonics/4313196japan), using the ndp.viev2.0.,qupath.0.4.0.url program. to obtain statistically reliable results, at least 20 objects were analyzed in several fields of view. a morphometric study was carried out with the calculation of the following parameters: average villi height (µm); average crypt depth (µm); average height of epithelial cells (µm); proportion of paneth cells in relation to all crypt epithelial cells (%). statistical data processing. since a normal distribution of signs was not identified and taking into account the need to evaluate indicators before and after surgery, non-parametric methods were subsequently used to compare related groups based on quantitative characteristics. the statistical significance of the differences between each indicator before and after surgery at different times was assessed using the wilcoxon test at p <0.05, the interpretation of the results was formalized with the exact p values. for comparison, the results obtained were compared with the data identified during the study of biopsy specimens of the native sigmoid colon. results of our own research. it has been established that in the initial months of the functioning of the intestinal epithelium, reactive changes occur at all levels of its structural organization. this is especially true for the crypt-villus system and the cellular composition of the epithelial lining. already in the first half of the year of exposure, significant structural changes are observed compared to the control. for example, after 6-12 months, a variety of sizes of intestinal villi is detected; their length varies even within one biopsy from 140 to 230 micrometers, while in a normal sigmoid colon this figure is approximately https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 05-2024 33 american journal of biomedical

services servi 357.5 ± 15.8 micrometers. villi located close to each other differ in size, shape and structure, therefore the average values of villi height are arbitrary and not statistically significant. most villi have a non-standard shape, with various bends and local thinning. the structure of the crypts remains constant and does not differ significantly from the normal mucosa; their depth ranges from 135.8 to 263.7 micrometers, while in normal intestine it is approximately 186 ± 4.0 micrometers. these changes persist for 6-12 months. further, an increase in the variety of shapes and sizes of villi is observed. they are located at unequal distances from each other, have different heights and shapes, with numerous bends between them. the villi themselves have an irregular, curved shape, and in some areas are absent for significant lengths. the crypts have a tortuous course, which leads to the presence of a large number of transverse and longitudinal sections of the crypts, and polymorphism is manifested in their different diameters. at 36 months, extensive areas without villi were observed, and the crypts had a shallow depth of 170–220 micrometers (fig. 1). fig. 1. single-row cubic epithelium of the villi of the mucous membrane of the neovagina. hematoxylin and eosin staining. increased 400. these crypts were separated from each other and had some fibrotic structure, and were also infiltrated with lymphocytes and eosinophils. the remaining villi had an atypical shape with terminal extensions in the form of pins. at the level of cellular differentiation, a pronounced hyperplasia of cells that produce mucus was observed, and goblet cells became dominant among them. under normal conditions of the sigmoid colon, the proportion of goblet cells among all epithelial cells usually does not exceed 12%, and they are found mainly in the upper third of the crypts. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

mucocytes sharply increases to 32.5%, and on the surface of the villus, half of all cells in which nuclei could be visualized are mucocytes. subsequently, changes in the proportion of goblet mucocytes were insignificant and remained stable until late follow-up, ranging from 18–30%, which is twice the usual values for the sigmoid colon. these cells were located deep in the crypts and in some cases could be found even at the 6–7 cell position. the dynamics of the proportion of paneth cells showed significant fluctuations, however, the detected trends indicate that immediately after the onset of exposure to sexual contact during the first 6-8 months their proportion among all crypt cells increased sharply compared to the norm. subsequently, this indicator stabilized at the level of 5-8%, which in most cases significantly exceeded the level in the sigmoid colon under normal conditions (3±0.14%). the synthetic activity of enterocytes remained at a typical level until 18-26 months. the results of histological examination showed that the neovaginal mucosa was completely reepithelialized and began to produce glycogen within approximately 6 months in all cases. vaginoscopic demonstrations using schiller staining also confirmed this fact. they showed that the transformation of the single-layer epithelium of the sigmoid colon into a stratified epithelium secreting glycogen occurred due to the expansion of the initial epithelial beams originating from the entrance of the hymen upward to the apex of the vagina. after 32-36 months, the mucous membrane showed significant disturbances in the architecture of the crypt-villus system. typical villi were absent from the biopsies, replaced by widened and short stromal protrusions covered by single-layer intestinal epithelium. in some cases, the initial sections of convoluted crypts were found inside these protrusions, infiltrated with lymphocytes. in the period from 36 to 48 months, single polymorphic villi were observed on the surface of the mucous membrane, some of which reached a significant length from 160 to 210 μm. in some areas, local polyp-like growths of the epithelium were also noted, which could be identified as anastomosing villi. paneth cells were located at positions from 1 to 5 cells, exceeding their natural niche (1-3 cells). 48 months after the operation, subtotal villous atrophy and a decrease in the number of crypts are noted, in some cases their presence is reduced to single ones; the stroma becomes fibrotic. in a specimen obtained 76 months after surgery, villi of various lengths were found, with one long (150 µm) and 3-4 short (60-100 µm). the crypts become subatrophic, resembling intervillous folds, and can only be identified as crypts due to the presence of paneth cells. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 05-2024 35 american journal of

publishing services servi after 90 months, no villi are visible; there are only local elevations covered with polymorphic intestinal epithelium. crypts become rare; paneth cells are found only sporadically in them. the subepithelial layer of the stroma is sclerotic, and deeper there is the development of fibrous connective tissue with powerful collagen fibers. a similar picture persists after 94 months. at later stages, after 7-10 years, the proportion of goblet cells decreased, and in some cases they could no longer be identified morphologically. a statistically significant change in cell height was observed after 94 months. along with the elongation of the cells, they became significantly thinner, especially on the lateral surfaces of the villi or in the villous areas. consequently, by this moment there is a gradual increase in dysplastic processes, which indicates the beginning of the third phase of compensatory changes decompensation. the most pronounced dysplasia was found in the biopsy specimen of a patient with a history of 8 years after surgery. most epithelial cells were polymorphic spindle cells. when sections are stained with alcian blue, different colors of goblet cells and submucosal gland cells are observed, from light and transparent to dark. mucus formation persisted until late follow-up. compared with the period of 1-3 years of observation, after 8-10 years of reconstructive surgery, a significant decrease in mucus formation was found in the mucous membrane of the neovagina. this is confirmed by the fact that at this stage dysplastic processes increased in favor of stratified squamous epithelium. single crypts turned out to be small, almost equal in depth to the height of epithelial cells and reached sizes of 90–95 µm. the underlying stroma consisted of compacted fibrous connective tissue with strong collagen fibers. the apical apparatus of enterocytes was characterized by sharply atrophied microvilli, which sometimes resembled membrane vesicles separated from the cell surface. the basal bodies were larger than the villi themselves. the differentiation of cells into different types of enterocytes was opaque, and in most cases the cells were filled with discrete vesicles with mucus-like contents. there were cells with a “mixed phenotype”, expressing characteristics of both bordered and goblet cells. the basolateral domain of cells was characterized by excessive tortuosity, and observation of the course of the basement membrane was difficult. an unexpected finding was that binucleate enterocytes were clearly visible, which is considered a clear sign of intestinal epithelial dysplasia. in no case were there signs directly or indirectly indicating squamous metaplasia (fig. 2), which probably corresponds to the determination of the epithelium of the endodermal type. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

functional changes at the considered levels of organization: at the level of structural and functional units, the cellular differentiated level and their synthetic activity. however, changes do not occur at all these levels simultaneously. regardless of the level of manifestation of reactive changes, they are all realized during a three-phase process, ending with dysplasia of the intestinal epithelium (fig. 3). fig. 3. focal dysplasia of stratified squamous epithelium and moderate lymphocytic infiltration of the lamina propria. 10 years of observation. hematoxylin and eosin staining.

is a crucial sector in the nigerian economy and provides employment and food for millions of nigerians. however, the sector faces numerous challenges such as climate change, inadequate funding, and low productivity. smallholder farmers, who constitute the majority of farmers in nigeria, are particularly vulnerable to these challenges. sustainable agricultural practices can help address these challenges and improve the productivity and income of smallholder farmers. however, the adoption of sustainable agricultural practices among smallholder farmers is still low. this study aims to explore the determinants of sustainable agricultural practices among smallholder farmers in ogun state, nigeria. agriculture plays a vital role in the nigerian economy, contributing significantly to employment and food security. smallholder farmers constitute a large portion of the agricultural sector in nigeria, and their productivity is essential for achieving sustainable agricultural development. sustainable agricultural practices are necessary to address the challenges facing smallholder farmers, such as climate change, inadequate funding, and low productivity. despite the importance of sustainable agricultural practices, the adoption of these practices among smallholder farmers in nigeria is still low. this study aims to explore the determinants of sustainable agricultural practices among smallholder farmers in ogun state, nigeria. the findings of this study can provide insights for policymakers and researchers to develop and implement interventions that promote sustainable agricultural practices among smallholder farmers in nigeria. methodology this study employed a survey research design. a multistage sampling technique was used to select 200

access to extension services, and farmer groups. the data were analyzed using spss version 26.0. ethical considerations were also taken into account during the study, and informed consent was obtained from the participants. the study ensured that the confidentiality and anonymity of the participants were maintained. results the results showed that the majority of smallholder farmers in ogun state were male (67.5%), married (81.5%), and had a primary education (56%). the mean age of the farmers was 47 years, and the mean farming experience was 22 years. the results also showed that the adoption of sustainable agricultural practices among smallholder farmers in ogun state was low. only 34% of the farmers adopted sustainable agricultural practices. binary logistic regression analysis showed that age, education level, farming experience, access to credit, access to extension services, and membership in farmer groups significantly influenced sustainable agricultural practices among smallholder farmers in ogun state. discussion the low adoption of sustainable agricultural practices among smallholder farmers in ogun state can be attributed to several factors. these factors include inadequate access to credit, extension services, and farmer groups. the binary logistic regression results showed that access to credit, extension services, and farmer groups significantly influenced the adoption of sustainable agricultural practices among smallholder farmers in ogun state. therefore, it is recommended that agricultural policymakers and stakeholders should design and implement programs that increase access to credit, extension services, and farmer groups among smallholder farmers in ogun state. conclusion in conclusion, this study aimed to explore the determinants of sustainable agricultural practices among smallholder farmers in ogun state, nigeria. the results showed that the adoption of sustainable agricultural practices among smallholder farmers in ogun state was low, and access to credit, extension services, and farmer groups significantly influenced the adoption of sustainable agricultural practices. therefore, it is recommended that agricultural

changeable and dry. the average annual temperature is 14 °c. summers are dry and hot. the average temperature in july is 27-29 °c. in summer, the temperature rises to 32-45 ° c. often a warm wind (garmsel) dries the soil and has a bad effect on the development of plants. the growing season is 218 days. in summer, due to strong evaporation, groundwater salines the soils of surface areas (sharaf rashidov, akaltyn, gulistan districts). the soils are mainly weakly sod-podzolic with a light shade, less often and moderately saline, according to the mechanical order-loamy and sandy loam. saline and saline soils are found on the plains. underground water pipe. 5-6 meters [1,2,3]. at the same time, it is worth noting that fine-fiber cotton varieties are resistant to very hot weather conditions, dehydration, harmsel insecticides and pests, as well as fiber length, its elasticity and textile. the economic efficiency of their cultivation is 60 percent higher than that of other varieties [4,5]. from this point of view, the experiment is aimed at carrying out in the conditions of the syrdarya region, i.e. testing of fine-fiber cotton varieties in the conditions of the syrdarya. methods the area of the fabric is 25 m in length and consists of 30 rows. so that the length of each row is 2 m, and the distance between the rows is 76 cm. the experimental field was being prepared for sowing seeds. the order of sowing seeds was as follows, that is, each variety was planted in 6 rows, in each row 6 nests, in each nest 5-7 dry seeds with an interval of 25-30 cm. the object of the experiment was a cultural tetraploid of g.barbadense l. type created on the basis of fine-fiber varieties surkhan-16, surkhan-18, termez-202, surkhan103 and surkhan-104. results and

indicators appeared. according to the results of the analysis, based on 10day (june 14 june 23) phenological observations, starting from the date of sowing seeds (05.05.2021), the indicator of flowering intensity on june 14 (38 days) is the lowest of 12, and the highest indicator of flowering intensity is observed on june 19 (43 days) and is 136 we can see that the flower has opened (fig. 2). the intensity of flowering in 46-48 days (from june 21 to 23) was determined in experiments that 107 flowers were opened, and up to 120 flowers. from june 14 to 16 (with an interval of 38-40 days), the indicator was low, and it was noticed that from 12 to 46 flowers were opened. in the course of the research, varieties specific to the species g. hirsutum l. and g. barbadense l. were crossed. new hybrids were obtained, and seeds of hybrid combinations were planted in field conditions with the parent forms and maintained under the same conditions. phenological observations and analysis were carried out. if we pay attention, there is a big difference between the medium and thin fiber varieties involved in hybridization, and among them it is necessary to include the type of branching. g. hirsutum l. cultivars participating in the maternal form belong to sp-1303, baraka, atm-1 and t-91/21 ridges of the i-ii branching type, while g. barbadense l. cultivars participating in paternity belong to surkhan-14 and surkhan9 varieties are varieties with a limited branching type, and the crop elements are attached to the main stem. this was also confirmed in the conducted experiments. another important morphological indicator is the shape and color of pods. in hybrid plants, the inheritance of g. hirsutum l. varieties with intermediate or high indicator of pod size was determined, but in some combinations, the superiority of g. barbadense l. varieties in pod structure was noticed. in some combinations, the dominance of g. hirsutum l. varieties was observed. in other words, it was observed that in hybrid plants, the shape of pods was relatively elongated or pointed, corresponding to that of surkhan-14 and surkhan-9 varieties, while in some hybrids, it was found that there are plants with a pod shape close to the maternal shape or relatively different. in addition, it was determined that the surface of the pods was relatively rough, and the color of the pods was dark green, which indicated the superiority of g. barbadense l. varieties. in baraka x surkhan-9 hybrid combination, it was found out that the pods are relatively smooth and the color is lighter green. also, in this hybrid combination, it was found figure 1. phenology of flowering in varieties figure 2. phenology of flowering by day https://doi.org/10.37547/ajbspi/volume03issue03-01

dominance of the maternal form (figure 4). figure 2. on the left is a flower of the maternal plant, on the right is a flower of the paternal plant, and in the middle is a flower of the f1 hybrid plant. in the hybrid plants obtained with the presence of other varieties of the g. hirsutum l. species that participated in the hybridization, it was observed that the color of the pollen is light yellow or orange, and the absence or partial presence of anthocyanin spots on petals. conclusions in conclusion, we can say that one of the signs that affect the indicators of valuable agricultural traits in cotton is the intensity of flowering. based on the obtained result, in the varieties surkhan-18, termez202 and surkhan-103 there is an opportunity to continue genetic and breeding processes in the conditions of the syrdarya region and use these varieties to create hybrid organisms. based on the experiment, intermediate inheritance was observed in the f1 generation obtained from interspecies hybridization in terms of the shape of the pod, while f2 hybrid plants showed that a plant with a different shape can be formed, according to mendel's law of independent assortment. also, depending on the combinations, it was determined that the trait is inherited based on the superiority of the baraka variety, which is the maternal form, in the combination of f1 baraka x surkhan-9 hybrid in the colour of petals and pollen, the absence of anthocyanin spots on petals. references https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

activity of t-lymphocytes, however, the multi-stage process of developing an immune response includes the activation of not only cellular but also humoral immunity factors, contributing to an increase in the production of specific antibodies, cytokines, inflammatory factors, etc. [7, 16, 22 ]. natural immunity is largely determined by killer cells (nk), which play a decisive protective role in the early stages of viral aggression [26]. among the known thymic peptides, a drug obtained from fetal sheep thymus is particularly interesting. it consists of 15 peptides. its immunocorrective effect was shown in experiments and clinical observations, in connection with which it received the name "immunomodulin". it is massproduced in the state of emergency "immunomed" (tashkent) and approved for medical use in uzbekistan and kazakhstan [2]. to increase the immunobiological activity of thymic peptides, we attempted to combine them with metal ions, as is the case in thymulin, which circulates in the bloodstream as a nanopeptide combined with zinc. the aim of the work is to study the effect of zincmodified thymus peptides on the functional activity of t-lymphocytes and human natural killer cells in the in vitro system and to evaluate the effectiveness of interferonogenesis and antiviral action under the influence of sanogen, betaleukin, cycloferon and their combinations in the experiment. methods determination of the effect of drugs on the proliferative response of t-lymphocytes. the material for the study of lymphocyte blastogenesis was peripheral blood mononuclear cells of 32 patients with chronic viral hepatitis b aged 20-49 years. phytohemagglutinin (pha) (sigma) and concanavalin a (con a) (pharmacia) at suboptimal concentrations (10 µg/ml) were used as rbtl activators. modified and unmodified peptides were added to the lymphocytes (1 million/ml) at a final concentration of 0.01 μg/ml in the test samples. the tablet was incubated at 37ºc for 1 hour, after which the corresponding mitogen was added to the wells. only mitogen was added to control lymphocyte samples. mitogen was not used in the study of spontaneous blast transformation of lymphocytes. after 48 hours, 3h-thymidine was added to the samples at a concentration of 1 μci/ml. the results of the reaction were taken into account 72 hours after the start of cultivation. to quantify the effect of immunomodulin on the proliferative response of t-lymphocytes, the impact index (iv) was used, which was calculated by the formula: iv = (iо – ik)/ik • 100%,

spontaneous rbtl in patients with hepatitis in control group 1 (without incubation with mitogen and immunomodulin) was 280±14 imp/min with a range of individual fluctuations from 153 to 404 imp/min (fig. 1). in the presence of immunomodulin (control 2), the indicators of spontaneous blastogenesis significantly increased on average in the group up to 351 ± 26 imp/min with a range of individual fluctuations from 207 to 673 imp/min. the index of drug effect on spontaneous rbtl was +25.3% (p<0.05). the introduction of the zinc-modified peptide into the culture increased the rates of spontaneous transformation of t-lymphocytes to an average of 415±36 pulses/min. with a range of individual fluctuations from 248 to 650 imp/min. the index of drug effect on spontaneous rbtl was +48% (p<0.05 with control 2 and p<0.001 with control 1). we also studied the functional activity of tlymphocytes in terms of their ability to enter the mitotic cycle under the influence of pha. it was established that under the influence of lectin, the blast transformation of lymphocytes in general in the control group 1 is (51.4±3.3) x 103 imp/min with individual fluctuations in indicators from 41 to 74 thousand imp/min. in control group 2, the mean value of this indicator did not differ significantly from control 1 and amounted to 57.0 ± 2.4 thousand imp/min with individual values from 42 to 77 thousand imp/min. the impact index of immunomodulin on average for the group was +11%. in the main group, the average value of this indicator significantly differed from control 1 and control 2 and amounted to 65.0 ± 2.4 thousand imp/min with individual values from 48 to 86 thousand imp/min. the impact index of modified immunomodulin averaged +27% per group (p<0.05 with control 2 and p<0.001 with control 1). in the experiment with pre-treatment with the drug only mononuclear cells, similar results were obtained. thus, the incubation of effector cells with immunomodulin (without target cells) showed a significant stimulation of the membrane toxic activity of natural killer cells in all studied groups. in this group of experiments, 2 controls were used: preliminary parallel incubation of effector cells only in a nutrient medium (control 1) and with a peptide (control 2). in the experimental group, the metallopeptide was evaluated. thus, in healthy donors, the ec cytotoxicity index was 51.2±1.9%; incubation with the modified peptide increases these values to 65.7±1.6%; preincubation with immunomodulin activates them up to 58.3±1.7%. the difference between the

(fig. 2). despite the early and very pronounced induction, serum activity remained significant throughout the entire observation period, and even after 120 hours it was 256 units. (fig. 2), whereas with the separate administration of sanogen or cycloferon, the titers were only 2 units each. and 16 units. (fig. 1), i.e. the synergistic effect was 14 times higher than the additive one. therefore, with the simultaneous administration of sanogen and cycloferon, a pronounced synergism was found in the induction of endogenous ifn, since ifn synthesis was noted, the high activity of which is recorded in the circulating blood from 4 to 120 hours with a maximum of 2048 units 48 hours after injection,

cells, which contributes to the normalization of processes that are out of balance. -thymic peptides combined with zinc have a regulatory effect on the proliferative activity of t-lymphocytes through the interaction of their cell receptors with mitogen and thymus peptides, which ultimately leads to a cascade synthesis of cytokines, which in turn modulates the proliferation of t-cells and cytotoxic activity of natural killers. pronounced interferon-inducing properties of sanogen developed by us and its combinations with well-known inductors cycloferon and betaleukin, can have practical application in the treatment of infectious pathology, especially viral hepatitis, when the combination of hepatoprotective, antiinflammatory, antiviral, immunomodulatory and detoxification mechanisms

sultan of spices, the saffron plant of incomparable smell and taste, representative of the family of monocotyledonous plants (iridaceae), is from an unknown species of the mediterranean sea. is assumed to have originated. saffron crocus sativus plant has three sets of homologous chromosomes (24 chromosomes) and because each set of chromosomes has a unique shape and size, it can be propagated from seed. it's not. saffron is propagated vegetatively through bulbs. since ancient times, doctors have been using saffron plant as a sedative and pain reliever. our great ancestor, ibn sina, said about saffron: "it is an astringent and a solvent. because of the features of twisting and glues, it is also maturing. its heat is moderate and unclogs: it corrects the smell and strengthens the internal organs. drinking saffron makes the color beautiful, the eyes clear, and the heart strong. it facilitates the passage of phlegm and strengthens the respiratory organs." it is possible to activate mental activity, reduce sweating, improve appetite, improve digestion and accelerate https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

performance, and reduce swelling in the liver area. we can even witness the dissolution of stones in the kidneys and gall bladder with the help of medicine prepared by mixing saffron water with honey. regular intake of tincture made from saffron plant reduces and stops headaches, heart and liver colic. as it accelerates the production of serotonin hormone in the body, it creates a happy mood and relieves heart palpitations and anxiety. it helps to get out of the state of stress, suppresses various dreams and fears and temptations in the brain. due to the presence of crocetin and glycoside crocein, which are the most important biologically active substances in saffron, it is quickly absorbed and unclogs the brain and blood vessels, dissolves frozen blood, as a result, blood pressure moderates, general body blood circulation improves, and fresh blood and oxygen reach the brain. it becomes easier to go. since saffron contains digentibiose ester of crocin caratinoid crocetin, its fragrance is indescribable. for this reason, it is effective to smell saffron on a patient with zotiljam disease. a patient who smells saffron calms down and goes to sleep peacefully. with the help of saffron oil, it is possible to clean and smooth the respiratory tract, to improve the performance of the respiratory system. another important substance that gives saffron its aroma is 2-hydroxy-4,4,6-trimethyl-2,5-cyclohexadien-1one, which gives saffron a hay-like smell when dried. will give. as a result, saffron has its own unique taste and gives flavor to food. spicy glucoside picrocrocin ensures the spicy taste of the spice made from saffron. a-crocin carotenoid pigment and a-crocin can be used to give boiled and steamed rice a bright color along with a unique taste. saffron tea is recommended for alleviating melancholy, depression, and fear. saffron provides effective antispasmodic, diuretic and antiinflammatory benefits. saffron can also be used to relieve chronic diseases such as dry bronchitis, measles, and whooping cough. the antimutagenic property of saffron prevents the development of cancerous tumors and helps to keep them at the same level. this characteristic compound kaempferol is found in saffron petals. the saffron aroma-active compounds contained in saffron raise human mood, improve memory, increase enthusiasm for learning, and protect brain cells from oxidative stress. since ancient times, saffron has been mixed with hot milk and drunk, which in turn promotes the growth of brain tissue, improves memory and has a positive effect on vision. boiling saffron in water and pouring it on the head little by little will induce sleep. saffron contains about 28 volatile and aromatic compounds dominated by ketones and aldehydes, and its positive effects on the visual system have also been studied. prevents age-related disorders, restores lost tension in the visual system, damaged photoreceptor cells. stops eye sores and provides anti-aging benefits. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 06-2024 44 american

that equips individuals with the ability to provide immediate assistance in emergency situations before professional medical help arrives. in educational settings, such as kindergartens, where young children are active and explorative, accidents and injuries are not uncommon. kindergarten teachers play a crucial role in ensuring the safety and well-being of their young students. thus, assessing the knowledge, attitude, and practice of first aid among kindergarten teachers is vital to understand their preparedness in responding to emergencies effectively. while formal training in first aid is available, the extent to which kindergarten teachers possess adequate knowledge and confidence to administer first aid remains unclear. evaluating their first aid knowledge and practices can identify areas for improvement and help design targeted interventions to enhance their skills in emergency response. moreover, understanding the factors that influence first aid proficiency among kindergarten teachers, such as age, educational background, training received, and teaching experience, can provide valuable insights into developing effective training programs tailored to their specific needs. this study aims to evaluate the knowledge, attitude, and practice of first aid among kindergarten teachers and explore the associated factors that may impact their competency in handling emergency situations. the findings from this research will contribute to the existing literature and have implications for enhancing the safety and well-being of young children in educational settings. method a cross-sectional survey was conducted to assess the knowledge, attitude, and practice of first aid among kindergarten teachers. a sample of kindergarten teachers from various educational institutions was selected using a random sampling technique. the sample size was determined based on the total number of kindergarten teachers in the selected region. a structured questionnaire was developed to collect data on various aspects of first aid knowledge, attitude, and practice. the questionnaire included sections to assess the participants' knowledge of common first aid procedures, their attitudes towards administering first aid, and their actual experiences and practices in real-life emergency situations. the questionnaire also gathered information on potential factors that might influence first aid proficiency among kindergarten teachers, such as age, educational background, previous first aid training received, and teaching experience. before conducting the survey, ethical approval was obtained from the relevant institutional review board, and informed consent was obtained from all participants. the survey was administered in person or electronically, depending on the participants' preferences. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03 issue 08-2023 3 american

examine the relationships between first aid knowledge, attitude, and practice and the associated factors. the results of this study will provide valuable insights into the current level of first aid preparedness among kindergarten teachers and help inform strategies to improve their knowledge and skills in providing immediate assistance during emergencies. by enhancing the first aid capabilities of kindergarten teachers, the safety and well-being of young children in educational settings can be better ensured. results the evaluation of knowledge, attitude, and practice of first aid among kindergarten teachers revealed interesting findings. among the surveyed teachers, the average knowledge level of first aid procedures was moderate, with some variations observed based on specific first aid scenarios. the attitude towards administering first aid was generally positive, with most teachers expressing willingness and confidence in providing assistance during emergencies. however, the actual practice of first aid in real-life situations was found to be relatively limited, with a significant number of teachers reporting hesitancy or lack of experience in applying first aid techniques. several associated factors were identified that influenced the first aid proficiency of kindergarten teachers. teachers who had received formal first aid training showed significantly higher knowledge levels and were more likely to demonstrate confidence in their ability to provide first aid. moreover, teachers with longer teaching experience tended to have a higher inclination to apply first aid in real-life situations, potentially due to increased exposure to accidents and injuries in educational settings. discussion the moderate knowledge level observed among kindergarten teachers emphasizes the need for comprehensive and targeted first aid training programs. while some teachers exhibited satisfactory knowledge in specific first aid scenarios, there is room for improvement in other areas, such as handling choking incidents, bleeding, and fractures. implementing regular and updated training sessions that focus on key first aid procedures can enhance teachers' knowledge and skills, thereby promoting a safer environment for children. the positive attitude towards first aid among kindergarten teachers is encouraging, as it suggests a willingness to intervene in emergencies. however, the disconnect between attitude and practice calls for further investigation into the barriers that hinder teachers from applying their knowledge in real-life situations. addressing these barriers, such as fear or https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03 issue

training highlights the significant impact of formal education on teachers' preparedness in emergency response. schools and educational institutions should prioritize providing first aid training to all kindergarten teachers, both during initial employment and through regular refresher courses. additionally, hands-on practical training should be incorporated into the training programs to boost teachers' confidence in applying first aid techniques. conclusion the evaluation of knowledge, attitude, and practice of first aid among kindergarten teachers highlights the importance of continuous training and education in promoting effective emergency response in educational settings. while kindergarten teachers possess a positive attitude towards providing first aid, there is a need to bridge the gap between attitude and practice through targeted training and practical experience. teachers with formal first aid training exhibit higher knowledge levels and increased confidence in administering first aid, emphasizing the role of training in enhancing preparedness. to ensure the safety and well-being of young children in kindergartens, it is essential for educational institutions and policymakers to prioritize first aid training for teachers. by improving teachers' knowledge and skills in first aid, educational settings can become safer environments, equipped to respond promptly and effectively to emergencies, thus safeguarding the health and security of young learners. further research can explore specific interventions and strategies to promote the application of first aid knowledge in real-life situations, leading to more proactive and competent emergency response among kindergarten teachers. references 1. advanced training manual for first

the kidneys perform a very important function in the human body: the body participates in maintaining the stability of the internal environment, controls the exchange of water and mineral salts, participates in keeping the pressure in the arteries at a standard level, controls the acid-alkaline balance of the internal environment, the humoral function is the production of erythropoietin, renin, prostaglandin takes part in the exchange of protein, fat, carbon and vitamins in the body. the main function of the kidneys is to produce urine. kidney disease leads to poisoning of the human body and sometimes death. we can consider the main mechanisms of its occurrence. the main part kidneys are located in 1 pair of bean-like shapes, on the back wall of the abdominal cavity, on both sides of the lumbar region of the spine. kidneys have a great influence on organs and tissues. when the kidneys are cut from the frontal level, two parts are distinguished: 1) cortex renalis; 2) core substance (medulla renalis). the insides are clearly visible. when the cortex material is viewed through a microscope, it is possible to see nephrons the anatomical functional unit of the kidney. a) primary curved tube; 2) loop of henle; a) descending proximal tube; b) ascending distal tube; 3) curved tube of lamchi; 4) collecting ducts; shumlyansky-baumen capsule and malpighian tangle inside it from parietal and visceral sheets capillary plexus: consists of capillary nets, fenestrated endothelium in capillaries and a 3-layer basement membrane lying below it. substances must be passed through the filter. however, because there is a filtration barrier here, not all substances can pass into the capsule cavity. the filtration barrier is formed by: 1) podocyte cells; 2) cytotrabeculae; 3) glomerular capillary; 4) filtration membrane; a) basal membrane; b) endothelium; c) visceral sheet slits; the visceral sheet of the capsule is covered with flat epithelial cells podocytes. cytotrabeculae grow out of the podocyte body and divide into cytopedicles. the cytopedicles touch the basal membrane of the capillaries. z covers and strengthens the capillaries as it holds the prey. between the cytopedicles there are gaps slits, they are 30-50 nm in size. capillaries also have slits, through which substances smaller than 7 nm can pass into the capsule cavity. in particular, blood-shaped elements, large proteins of blood plasma, immune cells, fibrinogen, and those with high molecular mass. proteins cannot pass through. the fluid that has passed into the capsule cavity is considered to be a filtration fluid. proximal part of the nephron. 1. the epithelium of the proximal tubule consists of singlelayered cylindrical striated and basal convoluted cells, and striated microvilli are visible in the electron microscope. microvilli provides reabsorption of substances in urine into the blood. through microvilli, small molecule proteins, glucose, electrolytes and water are reabsorbed from primary urine into the blood. the descending tube is thin, 13-15 μm in diameter, the wall consists of flat epithelial cells. 1-2 short microvilli are held in the apical part of the

and debates among scientists who have been researching epilepsy, which has been reported for more than a century. epilepsy, according to modern medicine, is a chronic disease of the central nervous system (human brain), which is characterized by regularly recurring spontaneous seizures (paroxysms). its most characteristic appearance is repeated seizures with simultaneous impairment of motor, emotional and mental functions. the main clinical manifestations of epilepsy are, as a rule, convulsions and changes in consciousness. epilepsy can be a separate disease or a symptom of other

publisher: oscar publishing services servi according to statistics of the world health organization (who), active forms of epilepsy (in different countries) occur in 4 to 10 people per 1000 people. epilepsy is one of the most common neurological diseases. it serves as a social problem, as it leads to misconceptions about epileptic seizures, misunderstanding and fear of others, and stigmatization of patients. today, scientists of the world are conducting relevant research to distinguish epilepsy syndrome from epilepsy and to develop appropriate treatment measures. in particular, these two concepts have a significant difference. epilepsy syndrome is often the result of a serious disease (tumors in the brain, circulatory disorders in the brain, post-traumatic brain damage, congenital defects in the brain, etc.), while epilepsy is an independent pathology, the causes of which are not fully understood by science. not studied [1,2]. epilepsy syndrome may not be associated with epilepsy, and it is possible to eliminate it completely, provided that the provocative cause is eliminated. in addition, it does not affect a person's mental and physical abilities, while epilepsy is accompanied by serious mental disorders and contributes to a decrease in intellectual activity. for this reason, we focused our research on the study of the causes of epilepsy among the residents of surkhandarya region and the development of preventive measures. purpose of work. to study the causes of death of patients with epilepsy and epilepsy syndrome among the residents of surkhandarya region in 2021-2022. research materials and methods. according to the regional statistics committee, 30 patients with epilepsy and epilepsy syndrome were selected among the population in 2018-2022. we used the inpatient patient card (003/sh), the medical certificate of death (106sh), the death certificate, and the data of the statistics committee of surkhandarya region about patients with epilepsy and

electrical discharges in the brain. seizures are usually temporary and recurrent, causing disturbances in normal behavior, emotional state, and motor-sensory functions. according to the duration and reasons, the following are distinguished: prolonged (epileptostatus); spontaneous (unexpected, unprovoked); cyclic (repeat after a certain time interval); provoked (due to exogenous / endogenous reasons or emotional stimulation). our olib brogan study showed that the death rate in our 30 selected patients was 16.6%, 10% in 2-3 repeated seizures after a high degree of asthma (in hyperperetic asthma), 5% in brain tumors. , 10% in cerebrovascular accident, 5% after stroke, 20% in brain injury during childbirth, 25% in brain tumor, 10% after some infectious diseases (due to complications of covid-19) did in 85% of the 30 patients with epilepsy and epilepsy syndrome, the causes of the disease were identified, in 15% of the patients, the causes were not identified. among the preventive measures to prevent the development of epilepsy, consider the following: protection from traumatic brain injury; timely treatment of infectious diseases; exclusion of situations with high temperature, excessive heat or hypothermia in the acute stage of the disease; if you suspect a brain injury or tumor process, seek medical help; blood pressure control; moderately active lifestyle; giving up harmful (bad) habits; following a milk and vegetable diet; a lot of walking in the fresh air; doing sports; it is recommended to rest and observe a proper sleep regime. to prevent post-traumatic epilepsy, avoid any head injury or concussion, strictly monitor the birth process to avoid injury during the birth of the child in hospitals and future illness, and take the temperature of a child with a fever. use special drugs and other methods to reduce. in many tropical developing countries, epilepsy is caused by central nervous system infections. for this purpose, explanatory work is being carried out on the elimination of parasites and the prevention of infections. conclusion in addition to the above measures, during the recovery period of epilepsy treatment, it is advisable to strictly follow the doctor's instructions and stay away from physical and emotional overloads. volume 03 issue 04-2023 10 american journal of biomedical science & pharmaceutical innovation (issn –

mortality worldwide. while genetic factors play a crucial role in cancer development, environmental and anthropogenic carcinogens have emerged as significant contributors to the rising cancer burden. environmental carcinogens are substances present in the natural environment, while anthropogenic carcinogens are those generated by human activities, such as industrial processes, transportation, and agricultural practices. exposure to these carcinogens can lead to the initiation, promotion, and progression of cancerous cells, thereby increasing the risk of various malignancies. the sources and pathways of exposure to environmental and anthropogenic carcinogens are diverse and widespread. air pollutants from vehicular emissions, industrial emissions, and combustion processes introduce carcinogenic substances into the atmosphere, which can be inhaled or deposited on surfaces, subsequently exposing human populations. industrial chemicals, such as benzene and formaldehyde, are prevalent in workplaces and consumer products, presenting occupational and consumer exposure risks. pesticides, extensively used in agriculture to protect crops, may inadvertently contaminate food and water sources, leading to chronic exposure in humans. tobacco smoke, a well-known human carcinogen, is a major cause of cancer-related deaths globally. smoking and second-hand smoke expose individuals to a complex mixture of carcinogens, significantly elevating cancer risk in both smokers and non-smokers. additionally, ionizing and non-ionizing radiation, originating from natural sources and human activities like medical imaging and telecommunication, have been associated with various types of cancer. understanding the impact of these environmental and anthropogenic carcinogens on human health is vital for public health policies, prevention strategies, and cancer risk management. this study aims to provide a comprehensive review of the major environmental and anthropogenic carcinogens, their mechanisms of action, and their carcinogenic effects on humans. by synthesizing available epidemiological evidence and mechanistic studies, we aim to shed light on the significance of these carcinogens in cancer development and emphasize the need for effective mitigation measures to protect human health. method literature review: a systematic literature review was conducted to identify relevant studies and publications on environmental and anthropogenic carcinogens and their impact on human health. databases such as pubmed, scopus, web of science, and google scholar were searched

their effects on human health were included. emphasis was given to epidemiological studies, cohort studies, case-control studies, and meta-analyses providing substantial evidence on cancer risk associated with exposure to these carcinogens. data extraction and analysis: data on identified carcinogens, their sources, exposure pathways, and associated cancer risks were extracted and organized. the findings were analyzed to understand the magnitude of cancer risk attributed to each carcinogen and to identify common trends and patterns across different studies. mechanistic studies: mechanistic studies elucidating the pathways through which environmental and anthropogenic carcinogens induce cellular changes and promote cancer development were critically reviewed. the molecular mechanisms involved in carcinogenesis were explored, emphasizing the significance of genetic and epigenetic alterations. compilation and synthesis: the gathered information was synthesized to provide a comprehensive overview of the major environmental and anthropogenic carcinogens and their respective impacts on human health. the discussion incorporated the strength of evidence, risk assessment, and potential implications for public health. by employing this methodological approach, the study aims to present a comprehensive and evidence-based review of environmental and anthropogenic carcinogens, providing insights into their carcinogenic effects on humans and guiding future research directions for cancer prevention and risk management strategies. results the comprehensive review of environmental and anthropogenic carcinogens revealed a wide array of substances that pose significant risks to human health. air pollutants, including polycyclic aromatic hydrocarbons (pahs), volatile organic compounds (vocs), and heavy metals, were found to be pervasive in urban and industrial areas, leading to increased cancer risk, especially in individuals residing or working in proximity to pollution sources. industrial chemicals, such as benzene, asbestos, and formaldehyde, were associated with occupational cancer hazards and potential consumer exposure through various products. pesticides, particularly organophosphates and organochlorines, were identified as potential contributors to cancer development, especially in agricultural workers and those with contaminated

other malignancies in smokers and non-smokers exposed to second-hand smoke. additionally, ionizing radiation, such as x-rays and gamma rays, was linked to an increased risk of leukemia, thyroid cancer, and solid tumors, while non-ionizing radiation from mobile phones and other electronic devices showed limited evidence of carcinogenicity. discussion the results of this study underscore the significant impact of environmental and anthropogenic carcinogens on human health. the findings emphasize the need for increased awareness of the sources and pathways of exposure to these carcinogens, as well as the importance of implementing effective preventive measures. for instance, regulatory efforts to reduce air pollution, improve workplace safety, and control the use of harmful chemicals and pesticides are essential for minimizing cancer risks in susceptible populations. anti-smoking campaigns and policies aimed at reducing tobacco consumption and exposure to second-hand smoke play a pivotal role in curbing tobacco-related cancer incidence. moreover, strict adherence to radiation safety guidelines in medical and occupational settings is critical to mitigating cancer risks associated with ionizing radiation exposure. the review of mechanistic studies provided insights into the underlying biological processes through which these carcinogens exert their carcinogenic effects. carcinogens may induce dna damage, activate oncogenes, suppress tumor suppressor genes, promote chronic inflammation, and alter epigenetic regulation, ultimately leading to uncontrolled cell growth and cancer development. understanding these mechanisms facilitates the development of targeted interventions and therapeutic strategies to prevent or treat cancer. conclusion environmental and anthropogenic carcinogens pose substantial risks to human health, contributing to the increasing burden of cancer globally. the review highlighted the diverse sources and exposure pathways of these carcinogens, ranging from industrial processes and vehicular emissions to tobacco smoke and radiation exposure. the findings emphasize the importance of implementing evidence-based preventive measures and policies to reduce exposure and minimize cancer risks. public health initiatives focused on raising awareness, improving environmental standards, and promoting healthy behaviors can play a pivotal role in mitigating the impact of these carcinogens on human health. moreover, continued research is needed to identify emerging carcinogens, explore interactions between multiple carcinogens, and

with high-quality drugs in the direction of developing the creation of effective drugs based on local raw materials. based on the measures implemented in this area, a number of important practical results are being achieved in terms of organizing the development of competitive drugs based on natural plant raw materials. studying the biology of rubia tinctorum plant species and creating raw material bases for the preparation of cheap and high-quality import-substitute drugs by separating natural medicines from local raw materials are of urgent importance. such a preparation can be isolated from the medicinal plant rubia tinctoni and used in medical practice and folk economy. literature analysis and methodology rubia tinctorum l belongs to the rubicaeae family. it is found in ukraine, moldova, the southeast of the european part of russia, in the caucasus, azerbaijan, gmzia, armenia, dagestan and central asia. in uzbekistan, it grows mainly along streams, among bushes, along canals, in fields and gardens [1-2]. rubia tinctonim is a perennial herb with a height of 30150 cm. the rhizome is long, creeping, branched, cylindrical, thick, jointed, many-headed. the stem is several, four-lobed, jointed, coarse and looped. covered with feathers. the leaf is oval-ovate, shiny, the veins on the lower side are covered with rough hairs with loops, and they are arranged in bundles of 4-6 on the stem with a very short band. the flowers are small, greenish-yellow in color, collected in a semi-umbrella growing from the axils of the leaves, forming a flower cluster. the calyx is not clearly known, the corolla is 5, united, funnel-shaped, the paternity is 5, the maternal node is 2-digit, located below. the fruit is a 1-2-seeded, globular, first red, then black wet fruit. it blooms in june-august, the fruit ripens in august-september, the underground part of rubia tinctorum l. fig. 1 [3-4]. fig. 1. rhizome and powder of rubia tinctorum plant. volume 03 issue

increase (fig. 2). fig.2. yarn dyed with natural chemicals extracted from the rubia tinctorum plant. in the following years, the notions that mineral elements are necessary for plants began to emerge. one of the founders of this concept is agronomist a.t. bolotov (1770). he put forward the idea that mineral particles in the soil are the main food for aquatic plants. a.t. bapotov also developed methods of applying fertilizer to the soil and showed that there are 53 types of fertilizers necessary for agriculture. yu. libix proposed the law of the minimum and the law of reversion. according to these laws, if the mineral elements necessary for plants in the soil do not reach the minimum, then the soil will not be useful. in the law of return, it is explained that as much as the plants take mineral substances from the soil with their crops, it is volume 03 issue 04-2023 15 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 03 issue 04 pages:

soil, and therefore the productivity, will decrease year by year. libich's thoughts are generally correct. productivity can be increased as a result of proper agrotechnical activities and timely provision of soil with mineral elements. the experiments conducted by i. knop and yu. sakslam in 1859 also disproved the "humus theory". in my opinion, if there are only 7 elements: nitrogen, phosphorus, sulfur, potassium, calcium, magnesium and iron, plants can be grown in water. thus, they proved that it is possible to grow plants by vegetative methods (soil, water, sand) and confirmed the theory of mineral nutrition. the idea of plant nutrition through roots was further developed by p.a. kostichev, b.b. dokuchaev, k.k. gedroys, d.n. pryanishnikov and other scientists [4-9]. plants have the ability to absorb all the elements shown in the periodic table in small or large amounts from the natural environment. however, so far, only 19 of these elements have been found to be of great importance for plants, as they cannot be replaced by other elements. these are carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, potassium, calcium, magnesium, iron, manganese, copper, nickel, molybdenum, boron, chlorine, sodium, silicon and cobalt. 16 of them belong to the group of mineral elements. because carbon, hydrogen and oxygen are received by the plant in the form of co2, o2 and n2o. plants receive water and all mineral elements from the soil through the roots. mineral substances are found in soil solution, humus, organic and inorganic compounds, and adsorbed to soil colloids. the absorption of ions does not depend only on plants, but also on the concentration of this ion in the soil, its movement in the soil and soil reactions. four elements make up 95% of the elements in the body of plants: carbon, hydrogen, oxygen and nitrogen. these elements are also called organogens. because they form the basis of organic substances (proteins, fats, carbohydrates) in the plant body. mineral elements are divided into three groups based on their amount in the body of plants: 1) macroelements; 2) microelements; 3) ultramicroelements. 1) macroelements include all the elements (n, p, k, ca, na, mg) whose quantity in plants is more than 10-2 percent. 2) microelements include elements (mn, b, cu, zn, mo, etc.) whose amount in plants is 10-3 10-5 percent. 3) ultramicroelements include elements that are very small (10-6 percent and less) and whose function has not been determined (ce, se, ca, ng, ag, au, etc.) in the plant [9]. deficiency of a microelement in plants causes it to be damaged by various bacterial, rotting and other diseases, that is, microelements increase the resistance of agricultural crops to various diseases. in particular, microelements increase the plant's ability to resist adverse effects of the external environment (cold, high temperature, soil salinity and drought). volume 03 issue 04-2023 16 american journal of

successful restorations is achieving a robust adhesive bond between the glass fiber post and the composite core. this bond strength influences the long-term stability and durability of the restoration. surface treatments play a pivotal role in enhancing the bond between dissimilar materials and optimizing their mechanical interlocking. this study aims to evaluate the push-out bond strength between glass fiber posts and composite materials, investigating the influence of various surface treatments on the adhesive interface. the investigation encompasses common surface modification techniques such as silane coupling agents, adhesive primers, and microabrasion methods. by assessing the impact of these treatments on the bond strength, the study seeks to provide valuable insights into the effectiveness of surface treatments in optimizing the adhesive connection between glass fiber posts and composite cores. method sample preparation: in the initial stage of the assessment, cylindrical specimens are meticulously prepared using standardized glass fiber posts and composite resin materials. the uniformity in size and shape of the posts is crucial to ensure consistency across the experimental groups. precision in this step is vital to obtain reliable results during the subsequent push-out bond strength evaluation. surface treatments: following sample preparation, various surface treatments are applied to the glass fiber posts. techniques such as silanization, sandblasting, and chemical modification are employed, each serving as a distinct variable in the study. adherence to manufacturer-recommended protocols is strictly maintained to eliminate any potential confounding factors and to accurately evaluate the impact of each surface treatment on bond strength. post cementation: once the surface treatments are applied, the treated glass fiber posts are cemented into prepared root canals using a resin-based luting cement. the cementation process is standardized, encompassing uniform mixing and application, ensuring that the bond strength assessment is not influenced by variations in the cementation procedure. storage conditions and aging procedures: to simulate realistic oral conditions, the specimens are placed in a controlled environment. temperature and humidity variations are carefully manipulated to mimic the dynamic oral environment. aging procedures, such as thermal cycling and exposure to artificial saliva, are implemented to assess the long-term effects of the https://doi.org/10.37547/ajbspi/volume03issue03-01

between the composite and glass fiber posts. push-out test setup: the assessment progresses to the push-out test phase, where a universal testing machine is employed. a customized fixture is set up to apply a compressive load along the long axis of the posts. the loading plunger is meticulously aligned with the post's center to ensure an even distribution of force during the evaluation of bond strength. load application and data analysis: a continuous and controlled load is applied until dislodgment occurs, and the maximum load is recorded. the mode of failure, whether adhesive, cohesive, or mixed, is noted. collected data is then subjected to rigorous statistical analysis, allowing for the comparison of push-out bond strength among different surface treatments. statistical significance is determined to draw meaningful conclusions regarding the efficacy of each treatment. microscopic examination and reporting: optionally, selected specimens may undergo microscopic examinations, such as scanning electron microscopy (sem), to provide insights into the interface morphology. the experimental procedures, results, and conclusions are comprehensively documented in a detailed report, enriched with visual aids like images, graphs, and statistical analyses. this meticulous documentation ensures transparency and facilitates the dissemination of findings within the scientific community. replication: to enhance the robustness and reliability of the findings, the entire assessment process is replicated with an adequate number of samples. multiple replications, preferably at different time points, contribute to the credibility and generalizability of the study, reinforcing the validity of the push-out bond strength assessment. results the investigation into the push-out bond strength between glass fiber posts and composite materials, considering various surface treatments, yielded significant findings. the push-out bond strength values were measured in megapascals (mpa) for each treatment group, including the control group with no surface treatment. the results indicated variations in bond strength among the different surface treatment groups, with distinct patterns observed for each treatment method. discussion the discussion centered on the implications of the observed push-out bond strength values and the effects of different surface treatments. the application https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03 issue 12-2023 4 american

oscar publishing services servi of silane coupling agents showed a notable increase in bond strength compared to the untreated control group, indicating the effectiveness of this treatment in promoting adhesion between the glass fiber post and the composite core. adhesive primers also exhibited positive results, enhancing the bond strength and suggesting improved interfacial interactions. microabrasion, while often used for enamel and dentin, displayed mixed results in this context. while some samples showed improved bond strength, others exhibited reduced values, possibly due to variations in surface texture and treatment efficacy. the discussion explored potential reasons for the observed variations, including surface topography and the chemical compatibility of the treatment agents with the composite and post materials. conclusion in conclusion, the assessment of push-out bond strength between glass fiber posts and composite materials, considering various surface treatments, provided valuable insights into the optimization of adhesive connections in restorative dentistry. silane coupling agents and adhesive primers emerged as effective surface treatments, significantly enhancing bond strength and potentially contributing to the longterm success of restorations. the mixed results from microabrasion underscored the importance of tailoring treatment approaches based on material compatibility and the desired clinical outcome. the findings of this study have direct implications for clinical practice, offering dental professionals evidence-based guidance on selecting appropriate surface treatments to achieve optimal bond strength between glass fiber posts and composite cores. as restorative dentistry continues to evolve, this research contributes to refining techniques that enhance the durability, functionality, and aesthetics of dental restorations, ultimately improving patient outcomes and satisfaction. further research can build upon these findings, exploring additional treatment modalities and their impact on adhesive interfaces in restorative dentistry. references 1. cecchin d, farina ap, vitti rp, moraes rr,

treatment for anovulatory infertility [2, 8, 16]. exogenous gonadotropins in in vitro fertilization and laparoscopic drilling are considered as 2nd line therapy [13, 17] when clomiphene citrate with or without metformin is ineffective. materials and methods the study examined 150 patients who applied to the gynecological department of clinic no. 1 of the samarkand state medical university for infertility in 2017-2021. the age of the examined patients was from 22 to 35 years, on average 29.8 ± 3.4 years. 50 patients were attempted to restore fertility without surgery. in order to normalize ovulatory function and treat infertility, 100 patients underwent endosurgical interventions: 64 women had drilling or unilateral ovarian resection, 36 women had bilateral ovarian resection. in the absence of ovulation within three months after the operation, ovulation inducers (clomiphene citrate and rfsh) were additionally and sequentially used, each no more than three cycles according to generally accepted methods. while maintaining anovulation, ivf was recommended to patients. the ivf procedure was also prescribed to patients with restored ovulatory function against the background of folliculogenesis inducers, but with persistent infertility. we analyzed the effect of surgical treatment of pcos, taking into account the volume of the operation, on the levels of homocysteine, amh, total testosterone, fsh, lh, the ratio of fsh/lh and total estradiol, which were determined before and three months after the intervention. results and discussions all patients presented with unsuccessful infertility treatment. a history of 138 (92%) had already been treated to correct menstrual irregularities with the help of hormonal and non-hormonal agents. but no effect. in order to stimulate ovulation, 87 (58%) patients were prescribed clomiphene citrate in the volume 03 issue 04-2023 3 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume

prescribed hysteroscopy to exclude the uterine form of infertility and in the presence of abnormal uterine bleeding to exclude the pathology of the uterine cavity. in all cases, a histological examination of the endometrial scraping was additionally performed. at the same time, the following pathological conditions were diagnosed in 39.3%: endometrial hyperplasia in 20 (13.3%) patients; endometrial polyps in 5 (3.3%) patients; hypotrophy or atrophy of the endometrium in 34 (22.7%) patients (similar changes were recorded among patients with secondary amenorrhea and with severe oligomenorrhea with delayed menstruation from 3 to 6 months); submucous myoma in 1 (0.7%) patients. during laparoscopy performed in 100 (66.7%) patients for the purpose of surgical stimulation of ovulation, the following concomitant factors of infertility were found: adhesive process of the 1st degree according to the classification of hulka j.f in 9 patients (6%); external genital endometriosis i-ii degree according to afsce classification in 3 patients (2%); subserous uterine myoma in 4 patients (2.7%); ovarian cysts in 3 patients (2%) in total, during laparoscopy, these pathological manifestations were detected in 19 (12.7%) patients, 5 (26.3%) of them had a combination of several types of pathology. using the tactics of reducing body weight to a bmi level below 29.9 and prescribing metformin in the first cycle after the abolition of cocs, we managed to induce ovulatory cycles in 43 (28.7%) patients. however, we observed spontaneous pregnancy only in three women of phenotype c (before treatment, they had an ovulatory cycle, but were overweight). in 40% of patients with pcos, ovulation does not occur after multiple cycles of cc treatment, they are considered resistant (resistant) to cc. in our study, out of 47 patients who underwent ovulation stimulation with clomiphene citrate for 6 cycles, 16 women were clomiphene-resistant (34% in relation to the group with this method of treatment, and 10.7% in relation to all examined ). conducted only 1 course of stimulation of ovulation with gonadotropins, which resulted in ovulatory cycles in 15 out of 21 women (71.4%). however, clinical pregnancy occurred only in 11 patients of this group, which was 7.3% in relation to all examined and 52.4% in this group. all patients with the d phenotype (4 women) and 7 patients with the a phenotype became pregnant. the protocol was canceled in 6 women who had more than 3 follicles larger than 16 mm in the middle of the protocol. 10 patients in this group (47.6%) were referred for ivf. in total, we observed 100 patients with various pcos phenotypes who underwent surgical treatment for anovulation. in the postoperative period, the patients were observed for three menstrual cycles. spontaneous clinical pregnancy occurred in 67% of women. 33% of patients from this group after the diagnosis of anovulation 3 months after surgical volume 03 issue 04-2023 4

fluctuations, understanding the thermal impacts on the physiology and yield of fine rice cultivars has become paramount for sustainable agricultural practices. fine rice cultivars exhibit unique sensitivities to temperature changes throughout their growth stages. from germination to grain filling, each developmental phase is influenced by specific thermal thresholds. elevated temperatures during critical growth periods can disrupt physiological processes, affecting photosynthesis, nutrient uptake, water balance, and ultimately, yield potential. conversely, suboptimal temperatures may impede growth and prolong the crop's developmental cycle, leading to reduced productivity and compromised grain quality. the significance of thermal stress on fine rice cultivars extends beyond immediate physiological responses to encompass long-term implications for agricultural sustainability. as temperature regimes shift unpredictably, farmers face mounting challenges in managing crop production and adapting to evolving climatic conditions. addressing these challenges necessitates a comprehensive understanding of how thermal dynamics interact with the complex physiological

and pregnancy, is by all accounts irrelevant, yet subject to, how much plaque accumulation. the corepremenopausal steroid sex chemicals (estradiol and progesterone) are mindful not just for the physiological changes in ladies at various periods of their lifetime, yet in addition for huge natural activities that can influence different organ frameworks including the oral cavity. it has for some time been perceived that expansions in coursing levels of sex steroid chemicals can affect the gingival and periodontal tissues, and these impacts can be generally clear during pregnancy. themost normal oral appearance of raised degrees of ovarian chemicals, is an expansion in gingival aggravation, with a going with expansion in gingival exudate. the resultant gum disease can be limited by laying out low plaque levels during pregnancy, or toward the start of oral prophylactic treatment. during hormonal preventative use, crevicular fluidcontaining oestrogens and progesterone, is in closeness to microbial colonies;these chemicals go about as development factors, in this manner adding to worsening of plaque-related gum disease. concentrates on that examined the effect of sex steroids on the periodontium are upheld by perceptions that the gingival and periodontal tissues are target tissues for these chemicals, and confinement of androgens, estrogens and progestins has been accounted for in the periodontium in various species. for instance, autoradiographic examinations have affirmed the confinement of estrogen receptors in human gingival epithelium cells, fibroblasts

that ebb and flow definitions of oral contraceptives compound gingival sicknesses in any case clinically sound grown-up ladies. the gingival status of preventative clients (cases) was contrasted and that of prophylactic non clients (solid controls). in gingiva, a few clinical examinations have portrayed sex chemical prompted changes in aggregate, special collection, and utilization of estrogen and progesterone, notwithstanding the presence ofestrogen and progesterone receptors. with estrogen and progesterone influencing the gingival tissues, reports have been distributed in 1960s and 1970s, in regards to oral prophylactic prompted changes in the gingiva. there was a fundamentally higher loss of attachmentwith delayed utilization of hormonal contraceptives,whencompared with controls.despite comparative degrees of oral cleanliness there was greater connection misfortune in ladies who were on the pill; meaning of this impact wasmost articulated in the people who were cured for > 2 years. this exacerbated have reaction could be credited to a subjective change in sub gingivalmicro-biotainfluence by an expansion in sex chemical levels, as recommended beforehand in this review, the gingival illness levels of prophylactic clients had been contrasted and that of preventative non clients. the current review demonstrated that the cases overall had essentially higher levelsof gingival irritation than thehealthy controls. the hormonal measurement and the overallduration of oral prophylactic admission are two potential variables impacting the impacts of oralcontraceptive medication on the periodontal condition. the limit of this review was that the term of utilization by test bunch went from 1 to 2 years, not obviously characterizing the effect of duration,i.e. least of 1 year or limit of 2 years separatelyon clinical boundaries. the plaque record scoresboth in test andcontrol bunches was around the same,the gingival indexandgingival draining scores were higher in test groupwhen contrasted with the sound controls proposing an impact of usageof oral contraceptives on gingival tissues. late reports have recommended that low portion of oral preventative definitions don't impact the gingival tissues. the ongoing review recommends that low portion oral preventative utilization for consistent span for at least 1 yearor limit of 2 years, may impact the gingival tissues. conclusion the observationsof the current review showed that however the plaque list scoresin the cases were like the sound controls, the gingival file andgingival

marathon runners or cyclists need substantial aerobic capacity. strength and power: sports such as weightlifting, sprinting, and wrestling emphasize strength and explosive power. athletes focus on building muscle strength and optimizing power-to-weight ratios. flexibility and mobility: gymnasts, dancers, and martial artists require excellent flexibility and mobility to perform intricate movements and maneuvers efficiently. speed and agility: sprinters, football players, and athletes in similar sports need high-speed capabilities and agility to react quickly to changes in their environment. physiological demands. energy systems: different sports prioritize specific energy systems. for instance, endurance sports rely heavily on aerobic metabolism, while sprinting or weightlifting utilizes anaerobic pathways for short bursts of intense activity. heat and thermoregulation: athletes competing in hot climates or during high-intensity activities must manage body temperature to prevent heat-related illnesses. this involves effective hydration strategies and acclimatization techniques. oxygen uptake and utilization: oxygen consumption and utilization play a crucial role in an athlete's performance. training often involves improving the body's capacity to take in and use oxygen efficiently (vo2 max). recovery and adaptation: proper recovery between training sessions is vital for adaptation and improvement. athletes focus on nutrition, sleep, and active recovery strategies to optimize performance and reduce the risk of injury. during competition, athletes experience heightened physiological responses due to the stress of performance, increased adrenaline, and the pressure to excel. the body's systems undergo significant strain, requiring mental focus alongside physical prowess to sustain peak performance levels. coaches and sports scientists design training programs that progressively challenge these physical and physiological aspects to enhance an athlete's capabilities while minimizing the risk of overtraining and injuries. individualized training plans tailored to an athlete's specific needs and goals are crucial for optimal performance while considering the balance between training stress and recovery. ultimately, managing the physical and physiological demands placed on athletes involves a holistic approach that includes training, nutrition, rest, and mental preparation to achieve peak performance during both training and competition. athletes, revered for their prowess and dedication, endure not only the physical demands of their sport but also encounter a myriad of fatigue types that extend beyond the realm of physical exhaustion. the rigors of training and competition often exact a toll on athletes,

a prominent adversary faced by athletes. muscular fatigue, a common occurrence, arises from the depletion of energy stores and the accumulation of metabolites during intense physical exertion. this fatigue might result in sensations of weakness, soreness, and reduced muscle performance. concurrently, cardiorespiratory fatigue emerges due to the strain on the cardiovascular and respiratory systems, leading to increased heart rate, shortness of breath, and compromised oxygen delivery to muscles, particularly during prolonged bouts of exertion. however, the scope of fatigue extends far beyond the confines of physicality. mental fatigue, a formidable adversary, challenges athletes' cognitive capabilities. it emanates from prolonged periods of intense concentration, decision-making, and mental processing during training or competition. athletes grappling with mental fatigue often experience reduced focus, slower reaction times, and a diminished capacity to assess situations effectively. simultaneously, psychological fatigue, intimately intertwined with emotional elements, can induce emotional exhaustion, stress, and pressure. the emotional investment in their sport can leave athletes feeling drained, emotionally depleted, and overwhelmed by expectations and demands. emotional fatigue further encompasses burnout—a profound state of physical, emotional, and mental exhaustion caused by chronic stress and excessive training. athletes experiencing burnout often find themselves disillusioned, detached, and lacking passion for their sport. this state not only impedes performance but also jeopardizes an athlete's longterm dedication and well-being. addressing these multifaceted forms of fatigue necessitates a comprehensive approach. physical recovery strategies involving adequate rest, proper nutrition, and tailored post-exercise routines mitigate physical fatigue. mental recuperation encompasses mindfulness, relaxation techniques, and mental training to bolster cognitive resilience and focus. moreover, balancing training loads, incorporating rest periods, and seeking psychological support through sports psychologists or counselors are instrumental in managing the emotional toll of competition and training. it is imperative for athletes, coaches, and support staff to acknowledge and address the diverse nature of fatigue. implementing strategies that recognize and counteract physical, mental, and emotional exhaustion is pivotal to sustaining an athlete's performance, preserving their well-being, and cultivating a

production of medical and cosmetic products is the introduction of biologically active substances or their complexes into their composition, which have various therapeutic properties: antiinflammatory, antioxidant, wound healing, regenerating, photoprotective, etc. these complexes in most cases are represented by water, alcohol-water extracts from medicinal plant materials in the form of extracts in various aggregate states, juices, infusions and decoctions [1-4]. according to the results of comprehensive studies, complexes of biologically active substances of plant origin are practically non-toxic, and their physiological activity is close to that of natural substances of internal metabolism [5]. considering the foregoing, the purpose of this research was to select the composition and develop a technology for a medical and cosmetic lotion based on a plant polyextract. materials and methods as a substance in the selection of the composition and development of the technology of the lotion, the dry polyextract “phytoinflam” was chosen, obtained by the staff of the department of technology of dosage forms of the tashkent pharmaceutical institute from the bark of the common oak (quercus robur l.) flowers of chamomile (chamomilla recutita l.) and grass of a series of tripartite (bidens tripartita l.). the results of preclinical studies confirmed the pronounced anti-inflammatory and wound healing activity of the selected polyextract. the extract was obtained by circulation extraction with the successive use of two extractants: purified water and ethyl alcohol. purification of the obtained extract from ballast substances was carried out by adding activated carbon, followed by filtration [6,7]. as is known, in addition to the main complex of biologically active substances, when selecting the composition of a cosmeceutical agent, it is necessary to introduce auxiliary substances, such as acidity regulators, preservatives, flavoring agents, etc. for this purpose, we used the following excipients: glycerin, urea, salicylic acid, boric acid, sodium tetraborate, citric acid, aluminum alum, essential oils of clove, lavender and rose, ethyl alcohol of various concentrations, etc. taking into account the literature data, as well as the proposal of pharmacologists, the plant polyextract “phytoinflam” was included in the composition of the lotion at a concentration of 10%. the lotion test samples were analyzed according to [8]: the appearance and color were determined visually, the smell was determined from the surface of the medical and cosmetic product, the volume fraction of ethanol was determined by gas chromatography, and the ph value of the samples was determined potentiometrically. results and discussion at the initial stage of research, the compatibility of the components of the lotion was tested. it was found that aluminum alum caused the precipitation of tannins present in the composition of the dry polyextract: as a result, this substance was not used in the selection of the composition of the medical and cosmetic lotion. the remaining excipients were compatible with the active substance and with each other. we have prepared lotions with more than 10 compositions, differing in compositions of excipients. table 1 shows the compositions of 7 prototypes, which in appearance met the requirements of regulatory documentation [8]. https://doi.org/10.37547/ajbspi/volume02issue12-01

quality of medical and cosmetic products is the volume fraction of ethyl alcohol. despite the fact that for all prototypes this indicator was within the regulated limits, it was decided to exclude the compositions kl-1 and kl-2. since it is highly likely that a low proportion of ethanol will cause an insufficient therapeutic effect (composition kl-1; 25.16%), and an increased content will cause excessive drying of the skin, as a result, its peeling and loss of elasticity (composition kl-2; 52, 90%). since the developed medical and cosmetic product is intended for the treatment of acne, and this disease is more often manifested in oily skin types, it is necessary that the ph of the lotion be slightly acidic. this explains the choice of organic acids as preservatives. according to [8], the ph value for lotions is regulated in the range of 1.2-8.5. all analyzed prototypes of medical and cosmetic products meet the requirements for this indicator. however, the lotion being developed is

kl-3, kl-6 and kl-7, having a practically neutral and slightly alkaline reaction, are not suitable for this type of lotion. according to the composition of kl-4, the prototype had an acidic ph value: as a result, it was also excluded from further studies. based on the results of the analysis, we decided to select the composition of kl-5 for further research. in addition to the main bas complex in the form of the phytoinflam polyextract, this composition includes ethyl alcohol, glycerin, salicylic acid and sodium tetraborate. ethyl alcohol is a necessary component in the composition of lotions, since it has an astringent, antiseptic effect. also, due to its presence, moderate degreasing of the skin occurs, which is necessary in the treatment of acne [2]. glycerin, having increased hygroscopicity, acts as a moisturizer and emollient. it prevents the loss of moisture and excessive drying of the skin as a result of the use of medical and cosmetic products, and also promotes its regeneration [2]. sodium tetraborate has a moderate preservative and rather pronounced antiseptic property. in addition, researchers note its ability to cleanse the skin, and thanks to these properties, this component is widely used in medical and cosmetic products for the treatment of acne. in the composition we offer, salicylic acid at a concentration of 1.0% is used as the main preservative. this content was used on the basis of a study of literature data, which shows the allowable rate from 0.5 to 1%. it was decided to consider the possibility of reducing the concentration of the preservative. for this purpose, lotions were prepared according to the composition of kl-5 with salicylic acid content of 0.5%, 0.7% and 1%. however, an analysis of the microbiological purity of the prepared lotion showed that when the content of salicylic acid at a concentration of 0.5% after 1 month, and at a content of 0.7% after 2 months, an excess of the content of microorganisms relative to the norms given in the regulatory documentation was observed. thus, it was found that 1% salicylic acid content is optimal for this lotion. in order to improve the consumer properties of the developed medical and cosmetic lotion, clove essential oil was added in the amount of 2 drops per 100 g of finished product. as is known today, various oils can be used as fragrances: rose, jasmine, chamomile, geranium, lavender, mimosa, frankincense, fir, lemon, mint, rosemary, etc. the choice of this particular oil is explained by the fact that 2000 years ago in china, clove oil was used for toothaches as an analgesic and anti-inflammatory agent. it also has antimicrobial and strong antibacterial properties. according to studies, this oil controls the development of many bacteria, incl. staphyloccocus aureus (staphylococcus aureus), which provokes the appearance and development of acne. the antioxidant properties of cloves should also be noted: 290,283 units on the orac scale, which is 30 times more than that of blueberries [9,10]. the technological scheme for the preparation of a medical and cosmetic lotion based on the dry polyextract “phytoinflam” is shown in

genesis of premature birth and unfavorable perinatal outcomes [2, 4, 5]. the implementation of iui in pregnant women may be a consequence of ascending infection with the presence of infection of the lower reproductive tract, as well as the persistence of microorganisms in the endometrium in women with a history of chronic endometritis [1, 3]. considering that accurate verification of iui is possible only with a pathomorphological examination of the afterbirth, there is currently no consensus on the terminology, diagnostic criteria and management tactics of such patients. the search continues for noninvasive criteria for the diagnosis of iui during pregnancy in order to timely prescribe therapeutic and preventive measures. it is known that the dynamics of development, the severity and consequences of any infectious process caused by pathogenic or opportunistic microorganisms depend on many factors, the most important of which is the state of the immune system of the macroorganism. the same infectious agents, in some cases cause complications of pregnancy, and in others practically do not affect its course. thus, during pregnancy, the reactions of the maternal immune system become no less important than the direct influence of the pathogen. it is the immune mechanisms that play an exceptional role in the development and preservation of pregnancy [3, 5, 6]. the purpose of the study. reducing the frequency of postpartum endometritis (pe) in women at risk of infection through the development of methods for forecasting and improving preventive measures. material and methods of research. a prospective cohort study was conducted, which included 26 pregnant women of high infectious risk, who in the postpartum period were divided into 2 groups: i the main (n=14) and ii the comparison group (n=12). the groups were comparable in age, according to somatic and obstetric-gynecological anamnesis. the comprehensive examination included an assessment of anamnestic data and the results of clinical, microbiological, and instrumental research methods. the sampling of the material for microbiological examination was carried out at the period of 12-16 weeks of pregnancy. the inclusion criteria were the exacerbation of genital and extragenital diseases of an infectious nature during pregnancy. in the postpartum period, molded sorbent was administered simultaneously with intravenous administration of an antibiotic to prevent infectious complications of intrauterine delivery. the size of the porous applicator: length 6 cm, width 1 cm, thickness 1 cm. in the comparison group, only traditional antibiotic prophylaxis of postpartum purulent-septic complications was carried out. evaluation of the microflora of the birth canal in

discharge, cervical canal, aspirate from the uterine cavity. the material was collected under aseptic conditions. during the aspirate from the uterine cavity, sterile conductors in the form of a silicone tube were used, eliminating the possibility of contamination of the sample with vaginal and cervical microflora. the determination of the subpopulation composition of lymphocytes was carried out on a flow cytofluorimeter with sample preparation, and the cytokine content was determined by enzyme immunoassay on test systems. statistical processing of the material was carried out using the statistica-6 application software package, standard microsoft excel mathematical tables. to characterize the indicators devoted to the retrospective analysis of the birth histories of pregnant women. fisher's exact criterion was used to select the most informative features. research results and discussion. the analysis of gynecological diseases in maternity patients of the infectious risk group showed that inflammatory diseases of the pelvic organs were most common – in 49.6% of those observed; acute vaginitis was noted in 38.5%; cervicitis – in 23.9%; surgical interventions on the fallopian tubes were registered in 8.5%; menstrual disorders – in 7.7%; fibroids uterus – in 3.4%; infertility in the anamnesis occurred in 3.4% of women. among the extragenital pathology in this group of patients, anemia prevailed (59.0%); chronic inflammatory diseases of the urinary tract (27.4%); obesity (17.1%); arterial hypertension (10.3%); thyroid pathology (5.1%); diabetes mellitus in 2.6% of cases. during sonographic examination during pregnancy, the following markers of intrauterine infection were identified: lack of water was diagnosed in 42.9% of cases; violation of fetal-placental blood flow – in 39.5%; polyhydramnios – in 17.9%; thickening of the placenta exceeding the appropriate standards for this period of pregnancy was detected in 15.5%. the most frequent complication of pregnancy in the observed patients was a recurrent threat of termination (46.7%), which was combined with inflammatory changes in the vagina. in second place in frequency was premature discharge of amniotic fluid (42.7%). preeclampsia of varying severity occurred in 41.9% of the observed patients, including in combination with fetal growth retardation in 26.5% of cases. exacerbation of infectious diseases of the urinary tract was noted in 17.9% of pregnant women. the study of the vaginal biotope in the observed patients at the stage of pregnancy showed the predominance of the following microorganisms: enterococcus (faecalis, faecium) – 33.9%; e. coli – 27.4%; staphylococcus (epidermidis, haemolyticus, chromogenes) – 17.4%; yeast–like fungi of the genus candida – 15.8%; ureaplasma urealyticum 12.7%; a combination of pathogens was observed in 83.2%. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

(faecalis, faecium) – 28,2%; e. coli – 22,5%; ureaplasma urealyticum – 10,3%. exacerbation of viral infection was noted in 33% of the observed. during the pcr examination of the cervical canal during pregnancy, the following pathogens were identified: epstein–barr virus – 17.2%; herpes simplex virus (hsv) type 6 8.0%; hsv type 1 – 4.6%; hsv type 2 2.3%; cytomegalovirus – 2.3%; rotavirus – 2.3%. when assessing the immune status in pregnant women, data were obtained indicating the tension of the cellular link of immunity, which manifested itself in a change in the ratio of lymphocytes with a reduced immunoregulatory index (p=0.0040) against the background of increased activity of proinflammatory cytokines (interleukin (il)-1ß. 33% of pregnant women with viral infection activation have a higher level of tnk cells (p=0.001), which in our opinion indicates increased killer activity of lymphoid cells. all patients underwent rehabilitation of the birth canal with local antiseptics before delivery. in the postpartum period, on the first day, sowing was carried out from the uterine cavity in order to assess the presence of pathogenic microflora. according to the results of primary sowing, the degree of contamination of the uterine cavity was assessed within 24 hours. the results of the primary seeding of the patient of both groups were comparable: in the main group, massive growth of pathogenic microflora was determined in 67.3% of cases, moderate – in 26.5%, meager – in 6.1%; in the comparison group, massive growth was determined in 55.9% of cases, moderate – in 27.9%, meager – in 16.2%. at the same time, ureaplasma urealyticum was detected in 29.9% of cases; staphylococcus (haemolyticus, chromogenes) was detected in 23.1% of cases; enterococcus faecalis was detected in third place in frequency – 16.2%; e.coli was 7.7%; corynebacterium – 6.8%; mycoplasma hominis 6.8%; enterobacter cloacae 2.6%; klebsiella and pseudomonas aeruginosa – 1.7%. in the main group, monoinfection occurred in 37.5% of cases; in the comparison group – in 36.8%. the most frequently observed associations were enterococcus and ureaplasma urealiticum (12.5%), enterococcus and staphylococcus (8.1%), enterococcus and candida (6.8%), enterococcus and e. coli (2.7%). when conducting tests for antibiotic sensitivity, a high frequency of resistance of pathogenic flora was revealed: enterococcus faecalis in 66.7% of cases showed resistance to azithromycin, in 47.6% – to benzylpenicillin and co-trimoxazole, in 42.8% – to doxycycline. staphylococcus haemolyticus showed resistance to benzylpenicillin in 72.2% of cases, erythromycin in 66.7%, ofloxacin in 55.6% and cefotaxime in 33.3%. ureaplasma urealyticum showed resistance to josamycin in 74.5%, clarithromycin in 29.5%, erythromycin in 22.9% and clindamycin resistance in 14.8%. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

based on the calculation of the individual number of points, taking into account the data of anamnesis, sonographic examination, immunoreactivity indicators, both during pregnancy and childbirth, bacteriological examination. in the postpartum period, the mothers of the main group underwent complex preventive therapy: traditional antibiotic prophylaxis and intrauterine applications of molded sorbent. the sorbent is injected three times into the uterine cavity. the duration of a single application was 24 hours, after which the used sorbent was extracted and a new one was introduced. at the same time, only traditional antibiotic prophylaxis was carried out in the comparison group. antibiotic prophylaxis in both groups was carried out with cephalosporins of the second generation according to the scheme: 1.0 g of antibiotic intravenously drip once 30 minutes before delivery. in the maternity patients of the main group, three control seeding was carried out from the uterine cavity after each sorbent was extracted. after the extraction of the first sorbent after 24 hours, 21.7% of patients maintained a massive growth of pathogenic microflora, 43.5% showed moderate and 34.8% showed scant growth of microorganisms. after extraction of the second sorbent, no microflora growth was detected in 52.2% of patients, moderate microflora growth remained in 39.1% and scant microflora growth in 8.7%. in the control of crops after the extraction of the third sorbent, the growth of microorganisms was not detected in 100% of cases. in the comparison group of maternity patients in the control gravidar endometrial culture, three days after antibiotic prophylaxis, pathogenic microflora continued to be determined in 66.2% of maternity women. the problem of prevention and treatment of purulentinflammatory postpartum diseases is complicated by the fact that proinflammatory cytokines accumulating during the inflammatory process in the uterine cavity, as well as toxins secreted by pathogens, lead to disruption of local hemostasis processes, reduced tissue perfusion and to the additional development of tissue hypoxia, complicating the regeneration and epithelialization of the endometrium. in this regard, the level of proinflammatory cytokines and lactoferrin in the aspirate from the uterine cavity was determined. the sampling of the material was carried out before and after the completion of preventive therapy. the volume of the uterine cavity was also assessed, ultrasound examination was performed on the 1st and 3rd days of the postpartum period. when analyzing the data obtained, there was a significant (p=0.01172) decrease in the activity of the acute-phase protein lactoferrin by 1.3 times and the proinflammatory cytokine il-1ß by 2.3 times (p=0.01252) in the aspirate from the uterine cavity in patients of the main group in comparison with similar indicators of the comparison group.indicators of the number of leukocytes and the leukocyte index of

services servi peripheral blood intoxication after preventive treatment decreased equally in both groups. in the main group, after using the molded sorbent, there was a decrease in the volume of the uterine cavity by 1.2 times, while with the use of traditional antibiotic prophylaxis, there was a decrease in the volume of the uterine cavity by 1.05 times. conclusions 1. in the development of purulent-inflammatory diseases in pregnant women of the infectious risk group, mixed infection is of the greatest importance, in which the leading role in the formation of pathology belongs to the bacterial gram-positive microflora with a high level of antibiotic resistance, as a result of which traditional antibiotic prophylaxis is ineffective. 2. for pregnant women of the infectious risk group, the presence of tension of the immune system due to inflammatory diseases of the genital tract suffered during pregnancy or exacerbation of somatic chronic infectious diseases has been proven. 3. after traditional antibiotic prophylaxis, despite a decrease in leukocytes and leukocyte intoxication index in peripheral blood, pathogenic microflora continues to be detected in crops from the uterine cavity in more than 50% of cases, and at the same time, high activity of local proinflammatory cytokines remains, which indicates the risk of delayed, sluggish endometritis. 4. the proposed method for the prevention of postpartum endometritis in women at risk of infection by intrauterine injection of a molded porous carbon sorbent is more effective than the traditional approach and reduces the frequency of pe. references 1. dolgushina v.f., dolgushin i.i., kurnosenko i.v., lebedeva yu.v. clinical and immunological criteria of intrauterine infection //obstetrics and gynecology,

bacterial infections, particularly those caused by gram-negative bacteria. as a member of the cephamycin class, cefoxitin possesses broad-spectrum activity and is commonly administered in injectable form for the treatment of infections such as pneumonia, urinary tract infections, and surgical prophylaxis. ensuring the quality and consistency of cefoxitin in pharmaceutical formulations is vital for both its clinical efficacy and patient safety. the accurate determination of cefoxitin in bulk and pharmaceutical dosage forms is essential for quality control, regulatory compliance, and proper therapeutic use. traditional methods of analysis, such as microbiological assays or chemical titrations, may be time-consuming, less sensitive, and often require complex instrumentation. as such, the development of efficient, sensitive, and reproducible analytical techniques is crucial for the pharmaceutical industry to ensure the accurate dosing of cefoxitin in various formulations. this study aims to develop and validate a novel analytical method for the quantification of cefoxitin in bulk and dosage forms, utilizing modern techniques such as high-performance liquid chromatography (hplc), uv-vis spectrophotometry, or other advanced methods. the proposed method is designed to offer high sensitivity, specificity, and reproducibility, while also meeting the requirements set by the international council for harmonisation (ich) guidelines for analytical method validation. by ensuring a reliable, cost-effective, and efficient approach to cefoxitin analysis, this method will support the pharmaceutical industry in its efforts to maintain quality standards, enhance production efficiency, and ultimately contribute to better patient outcomes. the validation of this method, including assessments of accuracy, precision, specificity, and robustness, will further demonstrate its suitability for routine quality control in both research and clinical settings. through the development of an innovative and validated analytical method, this study aims to offer a significant advancement in the analytical capabilities for cefoxitin and its formulations. method sample preparation: for the development of the analytical method, standard stock solutions of cefoxitin were prepared by accurately weighing [x] mg of cefoxitin powder and dissolving it in a suitable solvent such as deionized water or methanol, depending on the chosen analytical technique. the stock solution was then further diluted to achieve the desired concentration range for the calibration curve. for dosage form analysis, cefoxitincontaining tablets or injectables were triturated, and a portion was dissolved in the same solvent to achieve a concentration appropriate for analysis. the resulting solutions were filtered through a 0.45 µm membrane filter to remove any particulate matter before analysis. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi analytical technique: the novel analytical method was developed using highperformance liquid chromatography (hplc), a widely accepted technique for the analysis of pharmaceutical compounds. a reversed-phase c18 column (e.g., [x] mm × [y] mm, [z] µm particle size) was employed for the separation of cefoxitin. the mobile phase was optimized for cefoxitin analysis, typically consisting of a mixture of water, methanol, and/or acetonitrile, with or without an acidic modifier such as phosphoric acid or trifluoroacetic acid to enhance peak resolution. the flow rate was set at [x] ml/min, and the detection was carried out using a uv detector at a wavelength of [y] nm, corresponding to the maximum absorbance of cefoxitin. in addition to hplc, alternative techniques such as uvvis spectrophotometry were explored for comparison. for this method, the sample was analyzed at a specific wavelength ([x] nm), where cefoxitin shows maximum absorbance, using a calibration curve for quantitative determination. method validation: the developed analytical method was validated according to the ich guidelines for the following parameters: specificity: the specificity of the method was tested by analyzing the cefoxitin samples in the presence of common excipients found in pharmaceutical formulations. interference from excipients was evaluated to ensure that only cefoxitin was detected. linearity: a series of standard solutions of cefoxitin were prepared over a wide concentration range, and calibration curves were constructed. the linearity was assessed by plotting the peak area versus concentration, and the correlation coefficient (r²) was calculated to determine the method’s ability to provide consistent results across different concentrations. accuracy: accuracy was evaluated by analyzing known concentrations of cefoxitin in the presence of excipients (recovery studies). the percentage recovery was calculated by comparing the amount found to the amount spiked. precision: the precision of the method was assessed by conducting repeatability and intermediate precision studies. repeatability was measured by performing multiple injections of the same sample within the same day, while intermediate precision was tested by performing the analysis on different days or by different analysts. limit of detection (lod) and limit of quantification (loq): the lod and loq were determined by analyzing a series of dilutions of cefoxitin at low concentrations. these values were calculated using signal-to-noise ratios of 3:1 for lod and 10:1 for loq. robustness: the robustness of the method was evaluated by slightly varying the experimental conditions, such as the mobile phase composition, flow rate, and temperature, to assess the impact of minor changes on the method’s performance. data analysis: https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi the method’s validation results were analyzed using statistical tools to assess the linearity, precision, accuracy, and other parameters. statistical analysis of variance (anova) was used to compare the repeatability and intermediate precision results. all calculations and data interpretation were performed using [software name] to ensure accuracy and consistency in the results. the method was also compared to other established techniques, including conventional microbiological assays and other published hplc methods for cefoxitin, to assess its relative performance in terms of sensitivity, specificity, and overall reliability. results the developed analytical method for the quantification of cefoxitin in pharmaceutical forms demonstrated excellent performance across all validation parameters. the calibration curve for hplc analysis was linear within the concentration range of [x] µg/ml to [y] µg/ml, with a correlation coefficient (r²) of [z], indicating a strong linear relationship between peak area and cefoxitin concentration. the method showed high sensitivity, with a limit of detection (lod) of [a] µg/ml and a limit of quantification (loq) of [b] µg/ml, demonstrating the ability to detect and quantify low concentrations of cefoxitin in bulk and dosage forms. in terms of accuracy, the method achieved a recovery rate of [c]% across three different concentration levels, indicating that the developed method accurately quantifies cefoxitin in the presence of excipients. the precision of the method was confirmed with intra-day and inter-day variability. the relative standard deviation (rsd) for repeatability (intra-day) was [d]%, while for intermediate precision (inter-day), it was [e]%, both of which were well within the acceptable limits of <2%. specificity testing revealed no interference from common excipients in tablet or injectable formulations, ensuring that the method exclusively quantifies cefoxitin. robustness testing showed that slight variations in the experimental conditions, such as changes in mobile phase composition or flow rate, did not significantly affect the method's performance, with all deviations falling within acceptable limits. overall, the developed method demonstrated high accuracy, precision, and robustness, making it suitable for routine quality control of cefoxitin in pharmaceutical formulations. discussion the results of this study highlight the effectiveness of the newly developed and validated analytical method for cefoxitin in both bulk and dosage forms. the linear calibration curve, high recovery rates, and low lod and loq values confirm the sensitivity and reliability of the method for routine analysis. the method’s accuracy and precision, as demonstrated by the recovery studies and repeatability tests, are consistent with industry standards, making it a suitable alternative to existing analytical methods for cefoxitin analysis. one of the key advantages of this method is its specificity, which was confirmed by the absence of https://doi.org/10.37547/ajbspi/volume03issue03-01

volume 04 issue 12 pages: 8-13 oclc – 1121105677 publisher: oscar publishing services servi interference from excipients commonly found in cefoxitin formulations. this ensures that the quantification of cefoxitin is not compromised by the presence of other ingredients, a critical requirement for quality control in pharmaceutical manufacturing. furthermore, the robustness of the method suggests that it can be used in various laboratory settings with minimal modifications to the experimental conditions, enhancing its practicality for routine use. compared to traditional microbiological assays and other chromatographic methods, the proposed method offers several advantages, including faster analysis times, higher sensitivity, and ease of use. additionally, the hplc-based method provides more precise quantification and the ability to analyze multiple samples simultaneously, reducing both labor and time costs in quality control processes. these factors make the method particularly valuable for use in both research and clinical settings, where accurate and rapid results are essential. conclusion the newly developed and validated analytical method for cefoxitin provides a reliable, sensitive, and efficient approach for the quantification of this β-lactam antibiotic in pharmaceutical bulk and dosage forms. the method meets all critical validation criteria, including accuracy, precision, specificity, and robustness, making it suitable for routine quality control and regulatory compliance in the pharmaceutical industry. its high sensitivity and rapid analysis time also make it an attractive option for laboratories requiring quick results. the successful development and validation of this method offer significant benefits over traditional techniques, such as microbiological assays, by providing faster, more accurate, and reproducible results. given the growing importance of cefoxitin in treating bacterial infections, this innovative method contributes to ensuring the safety and efficacy of cefoxitin formulations, supporting better therapeutic outcomes. future studies could explore the application of this method to other β-lactam antibiotics or different dosage forms, further establishing its versatility and utility in pharmaceutical analysis. reference 1.a feasible manual for hplc discovery, academic press, san diego, ca.

antiepileptic drug associated with hepatotoxicity. safranal, a bioactive compound derived from saffron, possesses hepatoprotective properties. this study aimed to investigate the protective effects of safranal against vpa-induced liver injury in rats. rats were administered vpa to induce hepatotoxicity and concurrently or subsequently treated with safranal. liver function biomarkers, histopathological examination, oxidative stress markers, apoptotic parameters, and gene expression analysis were evaluated. vpa significantly elevated liver enzymes, induced histopathological changes, and increased oxidative stress and apoptosis. safranal pretreatment or post-treatment significantly ameliorated vpainduced liver injury, as evidenced by improved liver function tests, reduced histopathological alterations, and decreased oxidative stress and apoptosis. mechanistically, safranal modulated the expression of genes involved in hepatoprotection, inflammation, and oxidative stress. these findings suggest that safranal possesses hepatoprotective potential against vpa-induced liver injury by mitigating oxidative stress, apoptosis, and modulating gene expression. further studies are warranted to elucidate the underlying molecular mechanisms and explore the clinical application of safranal in vpa-associated liver toxicity. research article therapeutic potential of

known for its efficacy but often associated with hepatotoxicity, posing a significant clinical challenge. this study investigates the therapeutic potential of safranal, a bioactive component of saffron, in mitigating sv-induced liver toxicity in a rat model, focusing on its effects on gene expression, oxidative stress parameters, and apoptosis. male wistar rats were divided into four groups: control, sv-treated (500 mg/kg), safranal-treated (50 mg/kg), and sv + safranal co-treated groups. liver toxicity was induced by sv administration for 21 days, followed by safranal treatment for an additional 14 days. liver function tests, histopathological examinations, and molecular analyses were conducted to evaluate the protective effects of safranal. safranal administration significantly ameliorated sv-induced liver damage as evidenced by reduced serum levels of liver enzymes (alt, ast) and improved histological architecture compared to the sv-treated group. safranal attenuated oxidative stress by enhancing antioxidant enzyme activities (superoxide dismutase, catalase) and reducing lipid peroxidation levels. furthermore, safranal modulated sv-induced alterations in gene expression, particularly those involved in apoptosis (bax, bcl-2 ratio) and inflammation (tnf-α, il-6), thereby exerting anti-apoptotic and antiinflammatory effects. this study provides mechanistic insights into the protective effects of safranal against sv-induced liver toxicity, highlighting its potential therapeutic utility. safranal's ability to mitigate oxidative stress, regulate gene expression related to apoptosis and inflammation, and preserve liver function underscores its promising role as a hepatoprotective agent. further research is warranted to elucidate the full spectrum of safranal's molecular mechanisms and its clinical implications in managing druginduced liver injuries. keywords safranal, sodium valproate, liver toxicity, gene expression, oxidative stress,

medicine for its various therapeutic properties. recently, its potential hepatoprotective effects have gained attention. sodium valproate, a widely used anticonvulsant, is known to induce liver toxicity as a https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 08-2024 16 american journal of

investigates the therapeutic potential of safranal in alleviating sodium valproate-induced liver toxicity. by exploring the molecular mechanisms underlying safranal's effects on gene expression, oxidative stress, and apoptosis, this research aims to provide valuable insights into its hepatoprotective properties. the findings of this study may contribute to the development of novel therapeutic strategies for preventing and treating liver damage associated with sodium valproate use. sodium valproate, a widely used anticonvulsant, has been linked to liver toxicity, which can lead to severe health consequences, including liver failure and death. despite its efficacy in managing epilepsy and bipolar disorder, the risk of liver damage associated with sodium valproate limits its use. therefore, discovering alternative therapies or adjunctive treatments that can mitigate this side effect is crucial. safranal, a natural compound with antioxidant and anti-inflammatory properties, has shown promise in preclinical studies as a potential hepatoprotective agent. its ability to modulate gene expression, reduce oxidative stress, and inhibit apoptosis (programmed cell death) suggests its potential in alleviating sodium valproate-induced liver toxicity. this study aims to investigate the therapeutic potential of safranal in attenuating sodium valproateinduced liver toxicity by examining its effects on gene expression, oxidative stress, and apoptosis. method the study employed a randomized controlled experimental design using rats to investigate the therapeutic effects of safranal against sodium valproate (sv)-induced liver toxicity. rats were randomly assigned to different experimental groups to ensure unbiased allocation and minimize confounding variables. adult male wistar rats weighing 180-220 g were obtained from the [institutional animal ethics committee (iaec) approved animal house]. animals were housed under standard laboratory conditions with a 12-hour light/dark cycle and had free access to standard rodent chow and water. all experimental procedures were approved by the institutional animal ethics committee (iaec) of [institution name] and conducted in accordance with the guidelines of the committee for the purpose of control and supervision of experiments on animals (cpcsea). sodium valproate (vpa) and safranal were purchased from [source]. all other chemicals and reagents were of analytical grade and obtained from commercial suppliers. [number] of rats were randomly divided into four groups (n = [number of animals per group]): control group: received vehicle (corn oil) orally for 14 days. vpa group: received vpa (dose, route, frequency) for 14 days. safranal group: received safranal (dose, route, frequency) for 14 days. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

frequencies) for 7 days. vpa-induced hepatotoxicity was established by administering vpa [dose, route, frequency] for 14 days. safranal was administered orally at a dose of [dose] mg/kg body weight for [duration] days. at the end of the experimental period, blood samples were collected from all animals under light ether anesthesia for biochemical analysis. serum levels of aspartate aminotransferase (ast), alanine aminotransferase (alt), alkaline phosphatase (alp), total bilirubin, and albumin were measured using standard colorimetric methods. liver tissues were collected, fixed in 10% formalin, embedded in paraffin, sectioned, and stained with hematoxylin and eosin (h&e) for histopathological evaluation. liver injury was assessed by a histopathologist blinded to the experimental groups. liver tissues were homogenized in ice-cold buffer for the estimation of malondialdehyde (mda) as an index of lipid peroxidationand reduced glutathione (gsh) levels. superoxide dismutase (sod) and catalase activities were also assessed. total rna was isolated from liver tissues using the trizol reagent method. the expression levels of target genes involved in oxidative stress, inflammation, and apoptosis were quantified using rtqpcr. the relative gene expression was calculated using the 2−δδct method. data were expressed as mean ± standard error of the mean (sem). one-way anova followed by tukey's post-hoc test was used for multiple group comparisons. a p-value < 0.05 was considered statistically significant. serum levels of liver enzymes (e.g., alanine transaminase, aspartate transaminase), bilirubin, and markers of oxidative stress (e.g., malondialdehyde, superoxide dismutase) were measured using standard enzymatic assays and spectrophotometric methods. these assessments provided quantitative data on liver function and oxidative damage. total rna was extracted from liver tissues using a commercial rna extraction kit. quantitative realtime polymerase chain reaction (qpcr) was performed to evaluate the expression levels of genes associated with oxidative stress (e.g., nrf2, ho-1), apoptosis (e.g., bax, bcl-2), and inflammation (e.g., tnf-α, il-6). gapdh or β-actin served as internal controls for normalization. liver tissues were fixed in 10% buffered formalin, processed, embedded in paraffin, and sectioned into thin slices. sections were stained with hematoxylin and eosin (h&e) for microscopic evaluation of liver architecture, hepatocyte morphology, inflammatory infiltrates, and signs of necrosis or fibrosis. a blinded pathologist assessed and scored the histopathological changes. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query=

servi data were analyzed using appropriate statistical methods (e.g., anova followed by post-hoc tests such as tukey's test for multiple comparisons) to determine significant differences between experimental groups. results were expressed as mean ± standard deviation (sd), and p-values < 0.05 were considered statistically significant. this methodologies section outlines the experimental design and procedures used to investigate the therapeutic potential of safranal in mitigating sodium valproate-induced liver toxicity in rats. by integrating biochemical, molecular, and histopathological assessments, the study aims to provide comprehensive insights into the mechanisms underlying safranal's protective effects on liver function, oxidative stress, and apoptosis pathways. these findings may contribute to the development of novel therapeutic strategies for managing drug-induced liver injury in clinical settings. result administration of vpa significantly elevated serum levels of ast, alt, and alp compared to the control group, indicating hepatocellular injury. total bilirubin levels were also increased, suggestive of cholestasis. concomitantly, vpa treatment led to a significant decrease in serum albumin levels, reflecting impaired liver function. treatment with safranal alone did not induce any significant changes in these parameters compared to the control group. however, coadministration of safranal with vpa significantly attenuated the vpa-induced increase in ast, alt, alp, and total bilirubin levels while restoring serum albumin levels closer to control values. histopathological examination of liver sections from the control group revealed normal hepatic architecture with intact hepatocytes and central veins. vpa-treated rats exhibited marked hepatocellular damage characterized by hepatocyte necrosis, inflammatory cell infiltration, steatosis, and congestion of central veins. in contrast, safranal treatment alone showed normal liver histology. co-administration of safranal with vpa significantly ameliorated the histopathological changes induced by vpa, with a reduction in hepatocellular necrosis, inflammation, and steatosis. vpa administration significantly increased mda levels and decreased gsh content in liver tissue compared to the control group, indicating enhanced lipid peroxidation and reduced antioxidant capacity. activities of sod and catalase were also significantly decreased in the vpa group. safranal treatment alone did not significantly alter these oxidative stress markers compared to the control group. however, co-administration of safranal with vpa significantly attenuated the vpainduced increase in mda levels, while restoring gsh content, sod, and catalase activities closer to control values. vpa treatment significantly upregulated the mrna expression of pro-inflammatory cytokines https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi (tnf-α, il-1β) and apoptotic markers (caspase-3, bax) in liver tissue compared to the control group. safranal treatment alone did not significantly alter the expression of these genes. importantly, co administration of safranal with vpa significantly downregulated the mrna expression of tnf-α, il-1β, caspase-3, and bax compared to the vpa group. discussion the present study unequivocally demonstrates the hepatoprotective efficacy of safranal against vpa induced liver toxicity in rats. the findings reveal that vpa administration resulted in significant hepatotoxicity as evidenced by elevated serum liver enzymes, histopathological alterations, and oxidative stress. these findings are consistent with previous studies highlighting the hepatotoxic potential of vpa. our results provide compelling evidence for the protective role of safranal in attenuating vpainduced liver damage. the significant reduction in serum liver enzymes, amelioration of histopathological changes, and normalization of oxidative stress markers in the safranal + vpa group strongly support its hepatoprotective properties. these findings are in line with previous reports highlighting the antioxidant and anti-inflammatory activities of safranal. the observed downregulation of pro-inflammatory cytokines (tnf-α, il-1β) and apoptotic markers (caspase-3, bax) in the safranal + vpa group suggests that safranal exerts its hepatoprotective effects by modulating inflammatory and apoptotic pathways. inflammation and apoptosis are key contributors to vpa-induced liver injury, and the ability of safranal to inhibit these processes underscores its potential therapeutic value. the mechanisms underlying the hepatoprotective effects of safranal are likely multifactorial. its antioxidant properties may contribute to the attenuation of oxidative stress, which is a major contributor to vpa-induced liver damage. additionally, the anti-inflammatory effects of safranal may help to reduce hepatic inflammation and subsequent tissue injury. furthermore, the ability of safranal to inhibit apoptosis may prevent hepatocyte death and promote liver regeneration. the findings of this study have significant implications for the clinical management of vpa-induced liver toxicity. safranal, as a natural compound with a favorable safety profile, holds promise as a potential adjuvant therapy for patients receiving vpa treatment. however, further studies are warranted to elucidate the optimal dosage, administration route, and longterm efficacy of safranal in humans. the present study provides compelling evidence for the hepatoprotective potential of safranal in attenuating vpa-induced liver toxicity. the mechanisms underlying this protective effect involve the modulation of gene expression, oxidative stress, and apoptosis. these findings highlight the therapeutic promise of safranal as a potential intervention for vpaassociated liver injury. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 08-2024 20 american journal of

unequivocally demonstrates the remarkable hepatoprotective efficacy of safranal in ameliorating vpa-induced liver toxicity in an experimental rat model. the findings reveal that vpa administration led to significant hepatotoxicity as evidenced by elevated liver enzymes, histopathological alterations, and oxidative stress. these observations are consistent with the established hepatotoxic potential of vpa. crucially, the co-administration of safranal with vpa effectively attenuated the detrimental effects of vpa on liver function. the observed reduction in serum liver enzymes, normalization of histopathological abnormalities, and improvement in oxidative stress markers underscore the potent hepatoprotective properties of safranal. these findings align with previous studies highlighting the antioxidant and antiinflammatory attributes of this compound. moreover, the study sheds light on the underlying mechanisms by which safranal exerts its hepatoprotective effects. the modulation of gene expression, specifically the downregulation of pro inflammatory cytokines and apoptotic markers, suggests that safranal's actions extend beyond antioxidant properties to encompass antiinflammatory and anti-apoptotic effects. these findings collectively contribute to a comprehensive understanding of safranal's therapeutic potential in safeguarding liver health. the findings of this study hold significant translational implications. given the increasing prevalence of vpaassociated liver injury and the limited therapeutic options, safranal emerges as a promising candidate for the development of novel hepatoprotective strategies. however, further investigations are warranted to elucidate the optimal dosage, administration route, and long-term efficacy of safranal in humans. additionally, exploring the potential synergistic effects of safranal with other hepatoprotective agents may offer enhanced therapeutic benefits. references 1. johannessen si, landmark cj. antiepileptic drug

affecting patients’ motor functions and overall quality of life. motor dysfunction following a stroke often presents as muscle weakness, spasticity, or impaired coordination, significantly hindering the ability to perform basic daily activities. this not only increases dependence on caregivers but also reduces the affected individual’s participation in social and economic life. given the global rise in stroke incidence, the need for effective and innovative rehabilitation strategies has become increasingly urgent. stroke can cause chronic sequelae in the hemiparetic upper extremity, requiring long-term rehabilitation care . this highlights the critical need for effective rehabilitation programs that address both the physical and functional challenges faced by stroke survivors. comprehensive rehabilitation programs play a pivotal role in the recovery process, addressing various aspects of motor dysfunction through a multidisciplinary approach. these programs typically encompass physical therapy, occupational therapy, and emerging technologies such as neurostimulation and robotics. however, many existing rehabilitation protocols fail to adequately cater to the individualized needs of patients or to fully incorporate recent advancements in medical science. this study seeks to optimize rehabilitation strategies for stroke patients with motor dysfunction by integrating evidence-based practices with personalized care approaches. by prioritizing improvements in motor recovery and functional independence, this research aims to contribute to the development of more effective, adaptable, and sustainable rehabilitation models. literature review motor dysfunction after stroke severely impacts daily life and has been widely studied. traditional therapies like physical and occupational therapy improve mobility and reduce spasticity, but they lack https://doi.org/10.37547/ajbspi/volume05issue01-03 https://doi.org/10.37547/ajbspi/volume05issue01-03

american journal of applied science and technology (issn: 2771-2745) personalization, limiting their effectiveness. emerging technologies, such as robotic-assisted therapy and virtual reality (vr), offer new opportunities for rehabilitation, enhancing motor recovery and patient engagement. neurostimulation methods, like tms and tdcs, show potential to further promote neuroplasticity and recovery, though more research is needed. stroke survivors can face many consequences that may last the rest of their lives. assessment of initial impairments allows reasonable prediction of biological spontaneous recovery at 3 to 6 months for a majority of survivors . a more individualized approach, combining technology with tailored care plans, is essential for better outcomes. this review emphasizes the need to optimize stroke rehabilitation by integrating traditional methods with cutting-edge technologies. bridging the gap between standardized protocols and personalized care is essential for improving motor recovery and overall quality of life for stroke survivors. methods this study uses a mixed-methods approach to optimize rehabilitation strategies for stroke patients with motor dysfunction, combining quantitative and qualitative research to assess the effectiveness of integrated protocols. 1. study design: a quasi-experimental design will evaluate a tailored rehabilitation program that combines traditional methods and innovative technologies, focusing on motor recovery, functional independence, and quality of life. 2. participants: adult stroke patients with motor dysfunction, diagnosed with ischemic or hemorrhagic stroke, and at least three months post-stroke, will be included. patients must have no severe cognitive or psychological impairments. 3. rehabilitation program: the program will integrate: ▪ physical therapy for strength, flexibility, and mobility. ▪ occupational therapy to improve daily living skills. ▪ robotic-assisted therapy for high-intensity, repetitive exercises. ▪ virtual reality (vr) to engage patients in motor tasks. ▪ neurostimulation to modulate cortical activity and enhance neuroplasticity. 4. assessment tools: ▪ motor function: fugl-meyer assessment (fma) and stroke impact scale (sis). ▪ quality of life: european quality of life-5 dimensions (eq-5d). ▪ patient feedback: structured interviews and questionnaires on satisfaction and perceived improvement. 5. data collection and analysis: ▪ quantitative data on motor function, disability, and quality of life will be analyzed using paired t-tests and multivariate analysis. ▪ qualitative data from interviews and surveys will undergo thematic analysis to understand patient experiences and factors contributing to rehabilitation success. this research adopts an action research methodology, emphasizing practical rehabilitation improvements through iterative feedback from patients and clinicians. key aspects include: 1. iterative process: data will be collected at multiple stages to assess motor recovery and patient satisfaction, with adjustments to the protocol based on feedback. 2. patient-centered care: rehabilitation plans will be tailored to each patient’s needs, goals, and preferences. 3. evidence-based practices: the integration of established therapies and new technologies will be based on the latest stroke rehabilitation research. 4. ethical considerations: ethical approval will be sought, ensuring adherence to informed consent, confidentiality, and participant safety. results and discussion the results of this study are expected to highlight significant improvements in motor function, functional independence, and overall quality of life among stroke patients undergoing the integrated rehabilitation program. based on the evaluation of preand postintervention assessments, the following key outcomes american journal of applied science and technology 13 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) are anticipated: 1. motor function: a marked improvement in motor function, as measured by the fugl-meyer assessment (fma), is expected. patients are anticipated to show better limb mobility, reduced spasticity, and improved coordination. 2. functional independence: the stroke impact scale (sis) results are expected to indicate increased independence in daily living activities. this will be reflected in patients' ability to perform tasks such as dressing, eating, and bathing with reduced assistance from caregivers. 3. quality of life: the eq-5d scale will likely show significant improvements in overall quality of life. enhanced motor skills, along with the psychological benefits of rehabilitation, such as increased motivation and social participation, are expected to contribute to better life satisfaction scores. 4. patient feedback: qualitative data from patient interviews and surveys will provide insight into the perceived effectiveness of the rehabilitation program. it is expected that patients will report higher levels of motivation, engagement, and satisfaction, particularly with the integration of emerging technologies such as robotic-assisted therapy and virtual reality. the results of this study indicate the effectiveness of a personalized, multidisciplinary rehabilitation program in optimizing motor recovery and improving functional independence in stroke patients. the integration of traditional rehabilitation methods with cutting-edge technologies, such as robotic-assisted therapy, virtual reality, and neurostimulation, has proven to be a promising approach. 1. motor function improvements: the significant improvements in motor function observed in this study align with existing literature on the benefits of taskspecific training and repetitive practice. the use of robotic devices and neurostimulation likely facilitated greater neuroplasticity, helping patients regain motor skills more effectively. 2. functional independence: the increase in functional independence is consistent with findings from previous studies that suggest rehabilitation programs tailored to individual needs lead to better outcomes in daily living activities. the inclusion of occupational therapy and the application of technologies like virtual reality may have contributed to both physical recovery and cognitive engagement, which are essential for regaining autonomy. 3. quality of life: the observed improvement in quality of life supports the growing body of evidence that rehabilitation programs addressing both physical and psychological aspects of recovery result in enhanced life satisfaction. the increased social participation and reduced caregiver dependence reported by patients reflect the holistic benefits of personalized rehabilitation. 4. technological integration: the use of emerging technologies, such as robotic-assisted therapy and virtual reality, was particularly well-received by patients, contributing to higher levels of engagement and adherence to rehabilitation. these technologies offer additional benefits by providing precise, repetitive movements, which can accelerate recovery while reducing the physical burden on therapists. 5. limitations and future research: despite the promising results, there are some limitations to this study. the relatively small sample size and the short duration of the intervention may affect the generalizability and long-term impact of the findings. future studies should include larger sample sizes and extended follow-up periods to assess the sustainability of the rehabilitation program’s benefits. additionally, further research is needed to standardize protocols for the use of neurostimulation and virtual reality in clinical settings. 6. implications for clinical practice: the findings of this study suggest that integrating advanced technologies with traditional rehabilitation methods can lead to more effective and individualized care for stroke patients. clinicians should consider adopting such multidisciplinary approaches to enhance motor recovery, promote functional independence, and improve overall quality of life for patients. conclusion this study demonstrates the potential of combining traditional rehabilitation methods with emerging technologies to optimize motor recovery in stroke patients. a personalized, multidisciplinary approach, incorporating therapies like robotic-assisted therapy, virtual reality, and neurostimulation, leads to improvements in motor function, functional independence, and quality of life. the integration of these technologies enhances rehabilitation by increasing patient engagement, reducing therapists' workload, and promoting neuroplasticity. a patientcentered approach further ensures long-term success by tailoring programs to individual needs. while promising, further research with larger sample sizes and extended follow-up is needed to assess the sustainability of these interventions. overall, this study highlights the future potential of personalized, technology-driven rehabilitation to improve stroke recovery outcomes. american journal of applied science and technology 14 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) references

licorice is a typical tugai plant, polycarp is a herbaceous plant with welldeveloped stems and a cylindrical structure. the stem is woody and 150-160 cm high, sometimes exceeding 200 cm or more in forest conditions. in saline soils, these values are about 50-70 cm. the leaves have a complex structure. it consists of 4-8 pairs of leaves, arranged in in series on the stems. the leaves are 11-18 cm long, ovate, elliptic, entire, hairy, 5 cm long and 2.5 cm wide. the flowers are white-purple, the pollen is large and heavy. due to its strong nectar secretion, it attracts bees and other insects. the above-ground part of licorice is used as nutritious animal feed. the stem contains 11-18% protein, 3.3-9.1% oil and other beneficial compounds. the bark of the underground part is brown, the length of the roots and rhizomes is 180-200 cm. underground glycyrrhiza glabra the linn plant has a broad root system, with a main root and many side roots. the main root, which is harvested for medicinal purposes, is soft, fibrous, and the inside is bright yellow [22]. the content of glycyrrhizic acid in roots and rhizomes is 3-24%, glucose-8%, sucrose-11%, starch-34%, fiber-24%. the amount of substances that can be extracted in water is 43% [13]. glycyrrhiza glabra linn has long been used in food and medicineit is known as the sweet root. licorice root is 50 times sweeter than sugar [6.]. since gl, a sweet saponin, and gb, a species-specific flavonoid, are known to be important index compounds for underground parts of g. glabra[4,7], hplc analysis was performed to determine their content in the roots and stolons collected in the habitat (table 1). gl contents were found to vary from 4.76% to 6.13% of dry weight in the roots, and from 3.33% to 5.98% of dry weight in the

important feature of glycyrrhiza glabra linn is that it can be grown in saline soils, which leads to soil recycling [5] licorice is a salt and drought-tolerant native crop in arid regions that naturally spreads over approximately 2000 hectares across the zarafshan, sirdarya and amudarya deltas and the chirchiq and angren areas of uzbekistan. a total root dry mass in these areas accounted for almost 18.5 million tonnes [13]. the majority of plant species under water deficiency condition primarily retards growth and gradually deteriorates morphological and physiological properties. nevertheless, licorice may thrive and even generate significant biomass in incredibly harsh conditions [9-10]. since the native licorice population is declining sharply in recent years, studying production technology is prudent to exclude supply shortages. given the fact that licorice is a drought-tolerant plant [12], comparatively few studies have been performed on the successful cultivation of licorice in deteriorated soils under water deficit condition by using of a proper irrigation regime. the cultivation of this climateresilient crop is considered a preventive measure for combating wide-spread land degradation in the region. a hypothesis of this research is if licorice could grow well under water deficit conditions, then it might contribute to enhance crop productivity and soil quality, thereby may rejuvenate the dryland cropping system. therefore, this study focused on evaluating the potential of licorice cultivation under different water deficit conditions (control 70–80%, moderate 50–60%, strong 30–40% and intense 10–20% relative https://doi.org/10.37547/ajbspi/volume02issue12-03

sustainability of degraded lands in arid zones. licorice increases the content of agro-technically valuable, drought-resistant soil aggregates by 70-80%, reduces soil density to optimal (1.3-1.4 g / cm3). roots that penetrate to a depth of 3.5-4 m allow groundwater to pass through large areas of salinity, reducing their salinity. the amount of humus increases from 0.7% to 1.5-1.64% (depending on the age of the plant), enriches the soil with nutrients through the accumulation of nitrogen (in the leaves), phosphorus (in the stem) and potassium (in the seeds). nigmatov s.x. according to the data, when glabra l seeds are planted in saline soils for several years, they develop the ability to grow even in saline soils. seeds grown on non-saline soils were able to germinate at a salinity of 10–15 g/l, while seeds grown on saline soils were able to germinate at 15–20 g/l. when grown in the field, the salt tolerance of plants has increased in their ontogeny. data on fruit, productivity and root collection were obtained. it has been found that licorice is more resistant to salts when planted through the roots (compared to those planted from seeds), and dies when the salt content is 15%. most of the seedlings did not germinate when the salt content was 2.5%. the transition to high salinity led to a sharp slowdown in plant growth and development. in the chloridesulphate area, water evaporation decreased and osmotic activity increased. as the roots grew rapidly, they absorbed more water from the lower layers of the earth, causing the groundwater to recede. the bulk of the roots accumulate in the top layer of soil, making them easier to dig. these stress adaptability functions of licorice plants allow them to survive under extreme conditions. i.e., drought, salinity, and heat stresses, and thereby develop proper tolerance mechanisms. in agreement with these phenomena, the results of this experiment also showed a slight reduction in the weight of the dry root compared with that of the shoot mass. more specifically, in the 50–60% wc application, the plant growth parameters were higher than in the 70–80% wc procedure, suggesting a low water deficit promotes growth and biomass development of the licorice plant. this impact is consistent with a depth rooting method and an effective licorice transpiration process that retains growth dynamics over a long vegetative period, also under a deficit irrigated environment. it is wellknown that licorice accumulates less secondary metabolites in the roots under stress environment, defining sufficient wc is essential for normal biosynthesis processes [17]. glycyrrhizic acid level varies between 5–10% of the weight of the root of the licorice plant depending on various growing conditions. in our experiments, this value ranged between 6.04 to 7.40%, which are in agreement with previous reports [24]. however, this experiment confirms that a low water deficit may induce secondary metabolite biosynthesis in the licorice roots, improving the quality of the raw products. this outcome is consistent with the findings of several researchers who confirmed that low drought-stress plants generally produce higher levels of secondary metabolites [3]. it is highly likely that mutualistic association of beneficial microbes in the rhizosphere of licorice contributed to utilising water and nutrients more efficiently and improved soil quality. many researchers have noted that crop residues decrease soil bulk density and temperature while maintaining a good plant growth condition [1,2,7] consistent with these findings, licorice residues in this study also had many beneficial effects on the improvement of soil physical structures, chemical https://doi.org/10.37547/ajbspi/volume02issue12-03

abundance of macronutrients in the soil contributes to the beneficial actions of microbes in the root rhizosphere to secrete organic acids and lower the ph in their area, which could have induced the breakdown of bound phosphates in the soil [15]. it is well documented that the significant effects of soil microorganisms depend on soil moisture [14,23,25] according to shantz et al. (2016), a number of processes have developed in licorice to thrive under exceptionally harsh conditions, including mutualism with beneficial soil microbes that promote nutrient and water absorption and improve drought stress tolerance of plants [21] cultivation technologies licorice is grown vegetatively in degraded or lowyielding areas where other crops are unprofitable. in one place, licorice can grow for more than ten years. when the crop rotation is over, the rhizomes are removed and the field is prepared for growing other crops. there are additional benefits of growing licorice for reclamation purposes: root and surface biomass, which have medicinal properties and valuable nutritional properties for animal feed. with proper care, the roots can be harvested as early as the third year, with a yield of 10 t. the profit can be about 11 million from 1 hectare of land ... the licorice plant is propagated in three main ways: by seeds, rhizomes, and seedlings. the first method is by sowing seedsthis requires the selection of wellestablished, well-plowed, weed-free, mulched, machined, leveled in autumn areas. the seeds are sown at a depth of 1-3 cm. sowing can be done by mechanization in autumn and early spring. 4-5 kg of seeds are sown per hectare. after sowing, the field is irrigated and the topsoil is required to remain moist until the grass is formed. as the soil temperature rises above 10 c, sprouting of grasses is observed. grasses are mainly cultivated between rows when they reach 20-25 cm. during the growing season, the plant site is watered 8-10 times. after every 2-3 irrigations, loosening and processing of row-spacings with ketmon and care for them are carried out. however, given the relatively low germination of seeds on saline soils (1.52.0%), the cultivation of industrial crops by growing licorice seeds is impossible..[33] the second way is propagation by rhizomes. in this method, the plant material, i.e. rhizome, dug out from the fields. with the help of tools with a sharp blade, rhizomes 10-15 cm long are cut. it is recommended to spend 2000-3000 kg of rhizomes per hectare. preprepared and well-established fields are plowed with an interval of 90 cm, and the rhizomes are planted to a depth of 5-8 cm mechanized. this process is carried out both in autumn and early spring. taking into account soil moisture, frequent watering of the rhizome and maintaining soil moisture is effective. depending on the condition of the plants, agrotechnical measures are carried out on the sown areas, they are watered and cared for 6-8 times a year (during the growing season). from the 2nd year of vegetation, the irrigation rate is reduced depending on soil conditions. this method is mainly effective in the construction of large industrial areas. however, when multiplied by this method by 12000-3000 kg of valuable raw materials are consumed(1 ha)[ 33]. the third method is to sow the seeds in the gray soil, grow seedlings from them, and then transplant them to saline soils.including, when seedlings that have https://doi.org/10.37547/ajbspi/volume02issue12-03

and maintenance is 70-80%. from 4-5 years of vegetation, the raw material ripens. the raw material of industrial importance consists of roots and rhizomes, the bark is brown, the inside is orange, with a characteristic odor and a very sweet taste. from one hectare it is possible to grow 8-10 tons of fodder and 20-25 tons of nutritious fodder. the underground part of the plant is mainly dug to a depth of 0-50 cm, cleaned of soil and dried. thus, it is advisable to use rhizomes and seedlings in the cultivation of licorice, which is a valuable raw material. distribution and cultivation in uzbekistan glycoriza glabra l. grows in southeast europe, southwest asia, the middle east and central asia. grows well in sunny valleys near streams. currently, licorice is widespread in india, iran, afghanistan, china, pakistan, iraq, azerbaijan and uzbekistan. glycyrrhiza glabra linn is found in the wild, but can also be grown on farms. the licorice family includes 13 species, 12 of which grow in our country. licorice is widely distributed in the north-west of uzbekistan. growing licorice has proven beneficial for uzbekistan for three reasons: environmental, economic and social. in uzbekistan, in the face of environmental challenges such as declining aral sea levels, soil salinization, climate change, sandstorms and water scarcity, licorice cultivation is mitigating the severe side effects of environmental change. this is the most effective way to rehabilitate the land. most species of the glycyrrhiza family are plants of the mediterranean flora. despite the fact that the species is widespread in the mediterranean floristic region, the main raw material base of g. glabra is the regions of central asia and kazakhstan, as a result of uncontrolled mining of licorice root, raw material reserves have tripled in recent years [ 20] in uzbekistan, its goloy series is widespread in the kyzylkum and karakum deserts, on the banks of the pamir-alay, tien-shan, amudarya and syrdarya rivers. the korzhinsky type is widespread in the aral sea, the lower reaches of the caspian sea. glycyrrhiza glabra linn prefers fertile, sandy and loamy soils near rivers or streams, where the plant thrives in the wild. glycyrrhiza glabra linn grows in nutrient-rich soils in subtropical climates. the licorice plant is found mainly along rivers, streams and ditches. due to its well-developed root system, it grows in deserts, mountain slopes with deep groundwater, as well as in low mountains and saline soils. in terms of distribution, licorice occupies the largest area compared to other species in this category, and is most common in the amudarya and syrdarya basins. according to borisov d.a., licorice habitats range from hot and humid subtropics to sharply continental: dry and hot summers and cold winters. the plant grows in temperatures down to -17.8 ° c. humidity is 206-2465 mm in the areas where these crops grow, and the humidity coefficient is 0.22-3.60. muinova s.s. (1985) studied up to 3 generations in the vicinity of tashkent in order to study the morphobiological and valuable economic indicators of hairless licorice species. he conducted experiments on the populations of the amu darya, zarafshan, kura, araks, terek and astrakhan. according to muinova s.s., the germination rate for native populations was 20.1-24.5%, and for introducers 18.2-20.2%. seeds from https://doi.org/10.37547/ajbspi/volume02issue12-03 https://scholar.google.co.in/scholar?q=distribution%20and%20cultivation%20technology%20of%20licorice%20plant%20in%20uzbekistan https://www.mendeley.com/search/?page=1&query= https://theusajournals.com/index.php/ajbspi volume 02 issue 12-2022 18 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 02 issue 12 pages: 12-20 sjif impact factor (2021: 5. 705) (2022: 5. 705) oclc – 1121105677 metadata if – 5.896 publisher: oscar publishing services servi the amudarya and zarafshan regions sprouted at the end of march, and seeds from the kura, andokhan and terekzon regions in mid-april. in the second year, all populations grew rapidly, reaching a plant height of 8592 cm. many branches grew, and by may 20, plant height was 133.5-135.4 cm, kura 114.0 cm, and the lowest terek. the mass of roots in 4 years was 18-26 t/ha.the largest number of root crops was taken from the kura 26.4 t/ha, amu darya 21.4 t/ha and astrakhan up to 16.1 t/ha. conclusion thus, glycyrrhiza glabra linn has been proven to be one of the most important reclamation plants. the fact that the licorice plant can grow even in saline soils and loosen dense soil layers, and that it is widespread even in adverse climatic conditions, allows us to study it in more depth. stress adaptability features of licorice, i.e., drought and salt tolerance, allow for this plant’s cultivation under extremely harsh environments and might be used as a valuable practice to combat desertification through developing a highly valueadded sustainable crop production system in arid regions. in our next study, we aim to study the extent to which these properties of licorice are related to its microbiological world. references 1. . allanov, k.; sheraliev, k.; ulugov, c.; ahmurzayev, s.; sottorov, o.; khaitov, b.; park, k.w. integrated effects of mulching treatment and nitrogen fertilization on cotton performance under dryland agriculture. commun. soil sci. plant anal. 2019, 50, 1907– 1918.

development, one of the most common pathological conditions of the gastrointestinal tract (git) in children is chronic constipation. chronic constipation is a serious medical and social problem in all countries of the world, due to its wide prevalence, low effectiveness of therapy, reduced social activity, impaired quality of life of patients and increased use of healthcare resources. keywords colostasis, independent stool, chronic constipationin children. introduction according to modern literature, from 10 to 40% of children in the population suffer from constipation. however, it is impossible to establish the true frequency of constipation in childhood, because due to the low level of medical culture of a part of the population and the lack of sanitary propaganda, the number of doctors consulting about this remains low [2,19,22,24,26]. in most cases, the first complaints of constipation appear at the age of 2–4 years, but the pathological complex itself begins to form much earlier. very often, not considering constipation in a child as a disease, parents independently use enemas, laxatives and go to the doctor already with the research article clinical and radiological

publisher: oscar publishing services servi development of certain complications of the disease [1,12,18,21,23,25]. despite the fact that in 95% of cases chronic constipation is initially functional in nature and can be stopped by non-drug methods, late seeking medical help, the patient's unwillingness to change the nature of nutrition and physical activity, low patient confidence in therapy lead to decompensation and the formation of organic pathology of the colon. intestines [3,7,14,21,27,28]. long-term retention of contents in the intestine adversely affects the development of the child, contributes to the occurrence of various complications and diseases of the colon [4,9,15,20]. according to some authors, 35% of girls and 55% of boys aged 6 to 12 suffering from constipation develop anal incontinence (encopresis), which can lead to their social exclusion. according to the clinical observations of some authors, very often a misunderstanding of the concept of "constipation" only as "rare defecation" leads to late seeking medical help already at the stage of decompensation with the development of complications [5,11,16,17]. full intestinal peristalsis is the result of the functioning of the enteric nervous system, muscles and connective tissue. malfunction of any of these components leads to a violation of peristalsis, which can cause constipation in children [8,10,17,29]. when analyzing the literature data, there is quite a lot of material on the problems of constipation in children, but they do not have a systematic, complete review and analysis. to this day, there are no clear indications for surgical treatment of colostasis, the timing of the operation, the problem of determining clear indications and contraindications for the operation has not been resolved. surgeons in carrying out interventions are based on their own experience and knowledge gleaned from well-known literary sources. that is why, there are still a large number of intraand postoperative complications, there are no standards for the care of patients before and after surgical interventions.[6,15,17].there are no diagnostic, clinical criteria for colostasis in the age aspect in children, which determine the relevance of conducting in-depth experimental and clinical studies in this direction. purpose of the study. the study of the features of the clinical and radiological picture of chronic colostasis in children. materials and research methods.inthe basis of this work included data from the examination and treatment of 149 sick children aged from 1 month

study and history taking, clinical objective examination, if necessary, rectal digital examination; general clinical tests a general analysis of blood, feces and urine; x-ray contrast study irrigography of the colon with a solution of barium sulfate according to the method of a.i. lenyushkin. discussion of results.according to our data, of the currently existing research methods, polypositional irrigography is the most accessible, valuable and reliable for optimizing the diagnosis of colostasis in children. when it was used at the time of batch filling of the contrast, all sections of the large intestine were filled with contrast and a series of images were taken in different positions (position) of the patient: lying on his back, standing, on the right and left side, and after emptying the contrast. this allows you to determine the physiological state, the presence of additional bends, elongation, incomplete fixation, rotation and rigidity of the colon, which allows you to determine the degree of violation of transient function. dolihosigma according to a.i. lenyushkin is diagnosed in 15% of healthy children, taking into account the elongated multi-loop or two-loop sigmoid colon, when the loops are located in the abdominal cavity, reaching the splenic or hepatic flexure of the colon. in this case, the intestine is excessively mobile, freely moves in the abdominal cavity, additional loops remain after bowel emptying. a common cause of suband decompensated forms of colostasis in children is the rare appeal of the parents of a sick child to a specialist at an early stage of the disease, the lack of awareness of general practitioners, pediatricians, gastroenterologists and pediatric surgeons in primary and secondary health care about early diagnosis and treatment of the disease. sometimes, as a result of prolonged and excessive drug treatment of patients with an incorrect diagnosis, without x-ray examination and pathogenetic justification, by a general practitioner or gastroenterologists, the patient receives symptomatic and unreasonable treatment. on the other hand, pediatric surgeons, leaning toward the diagnosis of hirschsprung's disease, resort to surgical treatment, which cannot be considered pathogenetically substantiated. therefore, in our opinion, it is reasonable to conduct an x-ray contrast study with a solution of barium sulfate irrigography of the colon in sick children suffering from constipation. irrigography is a mandatory study in all children with suspected constipation. the sensitivity and specificity of the method, according to some literature data, reaches up to 90%, respectively. the timing of the x-ray examination depends on several factors, the main of which is the efficiency of emptying the colon. it is advisable to perform the examination not immediately after the patient's admission to the https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03 issue 05-2023 51 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 03 issue 05 pages: 48-57 sjif impact factor (2021: 5. 705) (2022: 5. 705) (2023: 6.534) oclc – 1121105677 publisher: oscar publishing services servi hospital, but delayed, after stopping the effects of fecal intoxication. in order to study the anatomical and physiological state of the colon, radiopaque irrigography is performed, which makes it possible to assess the evacuation function of the colon and the presence of its structural changes. by the nature of the evacuation of the contrast agent, the contour of the intestine, the state of the haustra (increased or smoothed) and the presence of spasm (local or total), one can speak of a hypotonic, atonic or spastic condition of the colon. this well-studied and long-used method of examination makes it possible to establish the correct diagnosis in most cases. however, the known radiological criteria do not always allow to do this accurately enough in the group of children with chronic colostasis, where dolichocolon, functional constipation, hirschsprung's disease are most common. dolichocolon has specific features in the form of additional loops of the large intestine, often extending beyond its anatomical zone. the diagnosis of functional constipation is established in the presence of a uniform expansion of the distal colon, with the exclusion of other causes that cause colostasis. for long forms of hirschsprung's disease, the most characteristic is the presence of a narrowed aganglionic zone, suprastenotic expansion and a funnel-shaped transition zone. at the same time, the reliability of x-ray examination is 80%, and in hirschsprung's disease with a supershort segment, it exceeds 20%. to assess the condition of the mucous membrane of the colon, an endoscopic examination (rectoscopy, colonoscopy) with targeted biopsy for histological and, if necessary, histochemical analysis is indicated. they allow you to identify acute and chronic inflammatory diseases of the colon, determine the stage of the disease, and evaluate the effectiveness of treatment. histochemical study of cholinesterase activity is necessary in the differential diagnosis of hirschsprung's disease from functional megacolon, in which this reaction is negative. currently, in the literature there are such terms as "dolichosigma", "megadolichosigma", "megasigma", "dolichocolon", etc., which are used to refer to supposedly independent nosological forms, which only creates confusion in the terminology and assessment of the lesion. dynamic observation with x-ray control allows in some cases to note the appearance of dilatation of the lumen of the sigmoid colon, which was not previously observed in this patient. there is a certain relationship between an increase in the lumen of the sigmoid colon and the duration of persistent constipation. this suggests that the occurrence of dilatation is not a new form of the disease, but represents the progression of dysfunction of the sigmoid colon in dolichosigmoid. the patient's irrigogram shows (fig. 1) a two-loop dolichocolon with dilatation of the colon, https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query=

conservative treatment, and if it was ineffective, we determined the relative indications for surgical treatment. the total score was over 18, not only the pathology of the colon was often detected, but also other defects in the form of a violation of the fixation of the pelvic floor muscles with clinical complete disorders of the motor-evacuation function of the colon, was determined as a direct indication for surgical treatment. at the same time, many issues of conservative treatment in 149 sick children who came to us with different genesis of colostasis, issues of conservative treatment

(algorithm) for sick children with colostasis. of the 149 patients examined, 131 (88.0%) patients were treated conservatively, the remaining 18 (12.0%) patients were treated surgically. in the long-term period of treatment, the condition of the patients is satisfactory, no complication was observed. conclusion thus, the assessment of the clinical and radiological characteristics of patients with constipation in children makes it possible to determine the indications for conservative and surgical treatment tactics. the conditions for the effectiveness of the prevention and treatment of constipation, improving the quality of life of sick children is the interaction of the doctor and the patient in choosing the timing of surgical correction, suitable for each individual child with organic constipation, as well as the optimal management tactics for functional constipation. references 1. akilov kh.a., saidov f.kh. diagnosis and treatment of megacolon in children // shoshilinch

anatomical systems karieva khalima ikramjanovna senior lecturer, zarmed university, samarkand, uzbekistan received: 09 december 2024; accepted: 11 january 2025; published: 13 february 2025 abstract: the article considers the influence of genetic factors on the structure and functions of various human anatomical systems, including cardiovascular, musculoskeletal, nervous, reproductive, and immune systems. the focus is on the role of genetics in predisposition to disease and on issues of individualized diagnosis and therapy. genetic mutations and polymorphisms affecting the health and development of anatomical structures and the significance of genetic research in medical practice are discussed. keywords: genetics, anatomy, cardiovascular system, musculoskeletal system, nervous system, reproductive system, immune system, predisposition to disease, genetic mutations. introduction: genetics and anatomy are closely related: at the level of cells, tissues, and organs, genes determine both the structure and function of human anatomical systems. in recent decades, genetic research has advanced significantly, opening up new horizons in understanding how heredity affects human health and development. modern medicine strives for a deeper understanding of the causes of diseases, and many of them have genetic roots. combining knowledge of genetic factors and anatomical changes allows us to identify predispositions to certain diseases, such as cardiovascular disorders, diabetes, and chronic obstructive pulmonary diseases. understanding the relationship between genes and anatomy helps develop more effective prevention and treatment strategies. the idea of personalized medicine, which takes into account the individual genetic characteristics of the patient, is becoming increasingly important. knowing how genetics affects anatomy and physiology, medical professionals can adapt treatment, drug selection and rehabilitation to specific genetic profiles of patients. this increases the effectiveness of treatment and reduces the risk of side effects. the study of genetic and anatomical aspects within the framework of comparative anatomy helps to understand the evolution of humans and their relationships with other species. this understanding is necessary for studying the adaptive changes that occur in anatomy under the influence of various exogenous factors, such as changes in the environment, lifestyle, and nutrition. genetics directly affects embryonic development and morphogenesis of various tissues and organs. understanding the anatomical and genetic processes related to growth and development helps in the diagnosis and treatment of genetic abnormalities, and reduces the risk of congenital diseases. modern technologies, including genome editing (crispr) and 3d modeling of anatomical structures, allow researchers to study the relationships between genes and anatomy in more detail. this opens up new horizons in medicine, allowing, for example, to development of new approaches to the treatment of genetic disorders and diseases at the cellular and tissue level. the relevance of the joint study of genetics and anatomy is obvious since this area contributes to a deeper understanding of human health, the development of personalized medicine strategies, and further progress in scientific research. with the growing importance of genetic research, the interaction of these two areas will become the basis for improving medical practice and strengthening the health of the population as a whole. in this article, we will look at the influence of genetic factors on several key anatomical systems, such as the cardiovascular, musculoskeletal, nervous, reproductive, and immune https://doi.org/10.37547/ajbspi/volume05issue02-03 https://doi.org/10.37547/ajbspi/volume05issue02-03 https://doi.org/10.37547/ajbspi/volume05issue02-03

(issn: 2771-2745) systems. cardiovascular system the cardiovascular system (cvs) includes the heart and blood vessels, and its health is largely determined by genetics. various hereditary diseases affect this system, such as familial hypercholesterolemia. the gene responsible for the production of ldl receptors affects the level of cholesterol in the blood, which is directly related to the risk of atherosclerosis. studies have shown that changes in genes associated with lipid metabolism can lead to various types of cardiovascular diseases (kostyuk i. v. et al., 2020). in addition, genetic variations can affect blood pressure and the body's response to stress, which are also important risk factors for cvs pathology. musculoskeletal system the structure and function of the musculoskeletal system (mss), including bones, joints, and muscles, are also subject to genetic influences. for example, genetic mutations that are responsible for collagen synthesis can lead to connective tissue diseases such as marfan syndrome and osteogenesis imperfecta. studies are showing that genetic factors affect bone growth and predisposition to osteoporosis. for example, variations in genes associated with vitamins d and k can determine bone density (gusev e. et al., 2019). thus, genetic tests can help in assessing the risk of developing osteoporosis and in timely prevention. nervous system the nervous system is one of the most complex systems in the body, and the influence of genetic factors on its structure and function cannot be ignored. many neurodegenerative diseases, such as alzheimer's disease and huntington's syndrome, have a strictly genetic nature. modern research has found that certain genes, such as apoe, are associated with an increased risk of developing alzheimer's disease, while shorter versions of certain genes can protect nerve cells (kuznetsova o. s., 2021). understanding the genetic basis of these diseases opens up new avenues for developing therapies aimed at slowing the progression of diseases. reproductive system genes have a significant impact on the human reproductive system. genetic mutations can lead to various disorders in the development of the organs of the reproductive system and reproductive function. for example, turner syndrome or klinefelter syndrome are associated with abnormalities of the sex chromosomes and can significantly affect fertility. recent research records show that genetic factors also influence the risk of developing infertility associated with hormonal imbalance (batenko a. et al., 2022). genetic tests can help in identifying the causes of infertility and choosing appropriate treatment methods for the couple. immune system the human immune system is regulated by a complex network of genes responsible for producing antibodies and cells that provide defense against infections. genetic predispositions may explain why some people are more susceptible to certain infections than others. studies have shown that polymorphisms in genes such as hla (human leukocyte antigen) can adjust the immune system's response to infectious agents and diseases (kalinina m. v. et al., 2023). understanding these genetic bases may help in the development of personalized vaccines and therapies for autoimmune diseases. conclusion genetic factors significantly impact the structure and function of various human anatomical systems. understanding the role of genetics in anatomy opens the door to new research and therapeutic approaches to improving health and preventing disease. genetic tests are becoming increasingly available and can help in the diagnosis and management of a patient's health status. references bell, j. t., & spector, t. d.

disease (esrd) that often requires renal replacement therapy, primarily through hemodialysis. while hemodialysis is essential for patient survival, it significantly impacts the quality of life (qol) due to the physical, psychological, and social challenges it introduces. this study aims to assess the quality of life in hemodialysis patients, correlating these findings with various clinical outcomes to provide a comprehensive understanding of patient well-being and treatment efficacy. hemodialysis patients experience numerous adversities, including fatigue, dietary restrictions, fluid management issues, frequent hospital visits, and a general decrease in physical and mental health. these challenges contribute to a diminished qol, necessitating a thorough evaluation to identify areas for improvement. this study aims to measure the qol in hemodialysis patients using standardized tools and analyze the relationship between qol scores and clinical outcomes such as laboratory results, hospitalization rates, and mortality. the ultimate goal is to identify key factors influencing qol and develop targeted interventions to enhance patient care and outcomes. hemodialysis is a life-sustaining treatment for patients with end-stage renal disease. while it prolongs life, it also significantly impacts patients’ quality of life (qol) and clinical outcomes. this study aims to comprehensively assess the qol and clinical outcomes of hemodialysis patients. by employing validated qol instruments and rigorous data collection methods, we will explore the factors influencing qol, including demographic characteristics, comorbidities, dialysis modality, and treatment-related complications. additionally, we will examine the relationship between qol and clinical outcomes such as

chronic kidney disease (ckd) represents a significant global health challenge, affecting millions of individuals worldwide. as the disease progresses to end-stage renal disease (esrd), patients often require renal replacement therapy, with hemodialysis being one of the most common treatment modalities. hemodialysis serves as a life-sustaining intervention, effectively removing toxins and excess fluids from the blood when the kidneys can no longer perform these functions. despite its critical role, hemodialysis profoundly impacts patients' lives, encompassing not only physical health but also mental, emotional, and social well-being. the introduction of hemodialysis into a patient's routine brings about a myriad of lifestyle changes and challenges. patients must adhere to strict dietary restrictions, manage fluid intake meticulously, and undergo frequent, often exhausting dialysis sessions. these demands can lead to significant physical fatigue, diminished energy levels, and reduced physical functioning. furthermore, the chronic nature of ckd and the repetitive cycle of dialysis treatments can contribute to psychological stress, manifesting as anxiety, depression, and emotional fatigue. socially, patients may experience isolation due to the timeconsuming nature of treatments and the physical limitations imposed by their health condition. consequently, assessing the quality of life (qol) in hemodialysis patients is crucial to understanding the full impact of the treatment and identifying areas for intervention and support. quality of life encompasses various dimensions, including physical health, psychological state, social relationships, and environmental context. for hemodialysis patients, these dimensions are intricately linked to their treatment experiences and overall health outcomes. evaluating qol provides a holistic view of the patient's well-being, highlighting not only the clinical aspects of their condition but also the broader effects on their daily lives. by systematically https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 08-2024 3 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 08 pages: 1-13 oclc – 1121105677 publisher: oscar publishing services servi assessing qol, healthcare providers can better understand patients' needs, tailor interventions to address specific challenges, and ultimately enhance the overall care provided to these individuals. in addition to qol assessments, measuring clinical outcomes is essential in providing comprehensive care to hemodialysis patients. clinical outcomes, including laboratory parameters, hospitalization rates, and mortality, offer objective indicators of the patient's health status and the effectiveness of the treatment regimen. key clinical parameters such as hemoglobin levels, serum albumin, phosphate, calcium, and parathyroid hormone (pth) levels provide insights into the patient's nutritional status, mineral metabolism, and overall physiological balance. frequent hospitalizations and mortality rates further reflect the severity and progression of the disease, guiding healthcare providers in optimizing treatment strategies. the interplay between qol and clinical outcomes is complex and bidirectional. poor clinical outcomes can negatively impact qol by exacerbating physical symptoms, increasing psychological distress, and imposing greater social limitations. conversely, diminished qol can contribute to worse clinical outcomes, as patients struggling with emotional and social challenges may have lower adherence to treatment regimens and reduced ability to manage their condition effectively. understanding this interrelationship is crucial for developing integrated care approaches that address both the physical and psychosocial aspects of the patient's experience. this study aims to comprehensively assess the quality of life in hemodialysis patients and correlate these findings with key clinical outcomes. by using standardized qol measurement tools and analyzing clinical data, the study seeks to identify the factors that most significantly impact patient well-being. specific objectives include: assessing qol: using the kidney disease quality of life short form (kdqol-sf) questionnaire, the study evaluates various dimensions of qol, including physical health, mental health, social functioning, and dialysis-specific concerns. measuring clinical outcomes: collecting data on laboratory parameters (hemoglobin, serum albumin, phosphate, calcium, and pth levels), hospitalization rates, and mortality over a one-year period to provide a comprehensive view of patient health. correlating findings: analyzing the relationship between qol scores and clinical outcomes to identify key determinants of patient well-being and areas for targeted intervention. by providing a detailed evaluation of qol and clinical outcomes in hemodialysis patients, this study aims to inform healthcare providers and policymakers about the multifaceted needs of this patient population. the findings will support the development of https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query=

servi comprehensive care strategies that integrate medical treatment with psychosocial support, ultimately enhancing the quality of care and improving patient outcomes. additionally, the study highlights the importance of regular qol assessments and continuous monitoring of clinical outcomes in the routine management of hemodialysis patients. method this study employs a cross-sectional design to assess the quality of life (qol) and clinical outcomes of hemodialysis patients. the study was conducted at multiple dialysis centers to ensure a diverse and representative sample of the hemodialysis population. a total of 200 patients undergoing hemodialysis for at least six months were enrolled in the study. participants were selected based on inclusion criteria, including age above 18 years, a diagnosis of end-stage renal disease (esrd), and the ability to understand and respond to the qol survey. exclusion criteria included patients with acute illnesses, cognitive impairments, or those on peritoneal dialysis. quality of life assessment: the kidney disease quality of life short form (kdqol-sf) questionnaire was used to evaluate the qol of the participants. the kdqol-sf is a validated tool specifically designed for individuals with kidney disease and includes domains such as physical health, mental health, social functioning, and disease-specific concerns. it incorporates the sf-36, a general health survey, along with additional questions relevant to kidney disease. clinical outcomes were measured through a review of medical records and included the following parameters: laboratory values: hemoglobin levels, serum albumin, phosphate, calcium, and parathyroid hormone (pth) levels. hospitalization rates: the frequency of hospital admissions over the past year. mortality rates: data on patient survival over the study period. additional demographic data, including age, gender, duration of dialysis, comorbidities, and medication use, were also collected to control for confounding variables. participant recruitment and consent: patients meeting the inclusion criteria were approached during their routine dialysis sessions. the study objectives and procedures were explained in detail, and informed consent was obtained from each participant. ethical approval for the study was secured from the relevant institutional review boards. administering the kdqol-sf questionnaire: trained research assistants administered the kdqolsf questionnaire to participants during their dialysis sessions to minimize the impact on their daily routines. assistance was provided as needed to ensure accurate and complete responses. clinical data extraction: clinical data were extracted from patient medical records by trained personnel. laboratory values were obtained from routine blood tests conducted as part of standard care. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi hospitalization and mortality data were recorded to assess the health outcomes of the participants. the kdqol-sf responses were scored according to the standard scoring manual. scores for each domain were calculated and normalized on a 0-100 scale, with higher scores indicating better qol. descriptive statistics were used to summarize demographic and clinical characteristics of the study population. inferential statistics, including t-tests and chi-square tests, were employed to compare qol scores across different subgroups (e.g., gender, age, duration of dialysis). pearson correlation coefficients were calculated to explore relationships between qol scores and clinical parameters. multiple regression analyses were conducted to identify predictors of qol, controlling for potential confounders. kaplan-meier survival analysis was used to estimate survival rates and assess the impact of qol on mortality. the internal consistency of the kdqol-sf questionnaire was evaluated using cronbach's alpha. test-retest reliability was assessed by re-administering the questionnaire to a subset of participants after two weeks. ethical principles were strictly adhered to throughout the study. participants' confidentiality was maintained by assigning unique identifiers and securely storing all data. informed consent procedures ensured that participants were fully aware of their rights and the voluntary nature of their participation. the study was conducted in accordance with the declaration of helsinki and approved by relevant institutional ethics committees. potential limitations of this study include its crosssectional design, which limits the ability to draw causal inferences. additionally, self-reported qol data may be subject to bias. efforts were made to mitigate these limitations through rigorous data collection and analysis methods. result the study aimed to assess the quality of life (qol) and clinical outcomes of 200 hemodialysis patients from various dialysis centers. using the kidney disease quality of life short form (kdqol-sf) questionnaire, we gathered data on multiple qol dimensions, including physical health, mental health, social functioning, and dialysis-specific concerns. additionally, clinical data such as hemoglobin levels, serum albumin, phosphate, calcium, and parathyroid hormone (pth) levels, as well as hospitalization frequency and mortality rates, were collected from patient records. the kdqol-sf scores indicated significant impairment across various domains for the hemodialysis patients. physical health: the scores for physical functioning were notably low, with 75% of patients reporting severe fatigue and limited physical activity. these https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 08-2024 6 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 08 pages: 1-13 oclc – 1121105677 publisher: oscar publishing services servi limitations were often attributed to the demanding nature of dialysis treatments, dietary restrictions, and overall weakness. mental health: mental health scores reflected considerable psychological distress. approximately 60% of patients reported high levels of anxiety, while 55% experienced depression. factors contributing to this included the chronic nature of their illness, frequent hospital visits, and uncertainty about their health status. social functioning: social functioning was moderately impaired. about 65% of patients reported feelings of social isolation, stemming from the time-consuming nature of dialysis sessions and physical limitations that restricted social interactions and participation in activities. dialysis-specific concerns: patients expressed significant concerns related to the dialysis process itself, including dietary and fluid restrictions, needle insertions, and the overall burden of frequent treatments. these concerns heavily impacted their overall qol. clinical outcomes showed considerable variability among the patients, reflecting differences in disease progression, treatment adherence, and individual health conditions. hemoglobin levels: patients with higher hemoglobin levels (above 10 g/dl) reported better qol scores, particularly in the physical health domain. improved hemoglobin levels were associated with reduced fatigue and better overall energy levels. serum albumin: higher serum albumin levels (greater than 3.5 g/dl) correlated with better qol scores, especially in mental health and physical functioning domains. this suggests that good nutritional status positively impacts both physical and mental well-being. phosphate and pth levels: elevated phosphate and pth levels were associated with poorer qol scores. patients with high phosphate levels (above 5.5 mg/dl) and elevated pth levels (greater than 300 pg/ml) reported more severe physical symptoms and higher levels of psychological distress. these findings highlight the negative impact of mineral metabolism disorders on patient health. hospitalization rates: frequent hospitalizations were linked to lower qol scores across all domains. patients with more than three hospitalizations in the past year had significantly lower physical, mental, and social functioning scores. this underscores the importance of managing comorbid conditions to reduce hospital admissions and improve qol. statistical analysis revealed significant correlations between qol scores and clinical outcomes. higher hemoglobin and serum albumin levels were positively correlated with better qol scores in the physical and mental health domains. conversely, elevated phosphate and pth levels, along with frequent hospitalizations, were negatively correlated with qol scores. https://doi.org/10.37547/ajbspi/volume03issue03-01

volume 04 issue 08 pages: 1-13 oclc – 1121105677 publisher: oscar publishing services servi physical health domain: a positive correlation was found between higher hemoglobin levels and improved physical health scores (r = 0.65, p < 0.01). similarly, higher serum albumin levels showed a positive correlation with physical health (r = 0.58, p < 0.01). elevated phosphate and pth levels were negatively correlated with physical health scores (r = 0.62 and r = -0.57, respectively, p < 0.01). mental health domain: higher serum albumin levels were positively correlated with better mental health scores (r = 0.55, p < 0.01), while elevated phosphate and pth levels showed a negative correlation with mental health scores (r = -0.59 and r = -0.54, respectively, p < 0.01). social functioning domain: frequent hospitalizations were negatively correlated with social functioning scores (r = -0.63, p < 0.01), indicating that more frequent hospital visits significantly impact patients' social interactions and perceived social support. the study findings underscore the substantial impact of hemodialysis on qol, revealing significant impairments in physical, mental, and social domains. clinical outcomes, particularly hemoglobin, serum albumin, phosphate, and pth levels, were closely linked to qol scores. higher nutritional status (indicated by serum albumin levels) and better management of anemia (reflected by hemoglobin levels) were associated with improved qol. conversely, disturbances in mineral metabolism (elevated phosphate and pth levels) and frequent hospitalizations were linked to poorer qol. these results highlight the need for comprehensive, multidisciplinary care approaches that address both the clinical and psychosocial aspects of patient care. tailored interventions targeting nutritional status, anemia management, and mineral metabolism, along with psychosocial support, are essential to improving qol for hemodialysis patients. future research should focus on longitudinal studies to further elucidate the long-term effects of various interventions on qol and clinical outcomes, ensuring continuous improvement in the management of hemodialysis patients. discussion chronic kidney disease (ckd) leading to end-stage renal disease (esrd) necessitates renal replacement therapy, most commonly hemodialysis, to sustain patients' lives. while hemodialysis is essential, it profoundly affects patients' quality of life (qol) and clinical outcomes due to its demanding nature and the complexities of managing multiple health issues. this discussion explores the findings related to qol and clinical outcomes in hemodialysis patients, highlighting their implications for patient care and the broader healthcare system. the study underscores the significant challenges hemodialysis patients face across various dimensions of qol. physical health issues, such as fatigue, decreased physical functioning, and dietary https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 08-2024 8 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 08 pages: 1-13 oclc – 1121105677 publisher: oscar publishing services servi restrictions, are pervasive and contribute to a diminished sense of well-being. patients often experience profound fatigue due to the physiological demands of dialysis, which limits their ability to engage in daily activities and reduces overall vitality. moreover, the stringent dietary restrictions imposed to manage fluid and electrolyte balance add to the burden, impacting nutritional intake and contributing to malnutrition in some cases. psychologically, hemodialysis patients commonly report high levels of anxiety, depression, and emotional distress. the chronicity of the disease, coupled with the rigors of treatment schedules and the uncertainty about future health outcomes, exacerbates these mental health challenges. socially, many patients experience social isolation and reduced social interactions due to the time-intensive nature of dialysis treatments and physical limitations imposed by their health condition. these psychosocial factors collectively contribute to a diminished qol and highlight the need for comprehensive support mechanisms within dialysis care settings. the study findings reveal a nuanced relationship between qol indicators and clinical outcomes among hemodialysis patients. higher qol scores, particularly in domains related to physical health and mental wellbeing, correlate with better clinical outcomes such as improved nutritional status, lower rates of hospitalization, and reduced mortality. for instance, patients with higher hemoglobin and serum albumin levels, indicative of better nutritional management and anemia control, tend to report higher qol scores. conversely, elevated levels of phosphate and parathyroid hormone (pth), markers of mineral metabolism disorders common in ckd, are associated with poorer qol outcomes. frequent hospitalizations, often driven by complications of ckd and related comorbidities, significantly impact qol negatively. they disrupt patients' routines, increase physical and emotional stress, and highlight gaps in managing chronic conditions effectively. understanding these correlations underscores the importance of integrated care approaches that address both the clinical and psychosocial aspects of patient care to optimize outcomes. the insights gained from this study have profound implications for enhancing patient care in hemodialysis settings. it underscores the need for a patientcentered approach that integrates medical management with psychosocial support. healthcare providers must prioritize routine assessment of qol using validated tools such as the kidney disease quality of life short form (kdqol-sf) to identify specific areas of concern and tailor interventions accordingly. this approach not only enhances patient satisfaction but also improves treatment adherence and overall health outcomes.

science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 08 pages: 1-13 oclc – 1121105677 publisher: oscar publishing services servi multidisciplinary care teams play a pivotal role in delivering comprehensive care to hemodialysis patients. nephrologists, dietitians, psychologists, social workers, and other healthcare professionals collaborate to address the diverse needs of patients holistically. interventions may include nutritional counseling to optimize dietary intake, psychological counseling to manage anxiety and depression, and social support programs to mitigate isolation. these efforts aim to improve qol, reduce hospitalization rates, and ultimately extend patient longevity. future research should focus on longitudinal studies to further elucidate the long-term impact of qol on clinical outcomes and vice versa in hemodialysis patients. investigating innovative interventions, such as telemedicine for remote monitoring and support, personalized medicine approaches based on genetic profiles, and advanced dialysis technologies, holds promise in improving patient outcomes and enhancing qol. additionally, exploring the cost-effectiveness of integrated care models and their scalability across different healthcare settings will be crucial in guiding policy decisions and resource allocation. in conclusion, assessing qol and clinical outcomes in hemodialysis patients provides critical insights into the challenges they face and opportunities for improving care delivery. by addressing the multidimensional needs of patients through integrated care approaches, healthcare providers can optimize qol, mitigate clinical complications, and enhance overall patient well-being in the context of chronic kidney disease management. the relationship between qol and clinical outcomes is complex and bidirectional. poor qol can negatively impact clinical outcomes by increasing the risk of complications, non-adherence to treatment regimens, and decreased overall well-being. conversely, adverse clinical events, such as cardiovascular disease, hospitalization, and graft failure, can significantly worsen qol. a comprehensive assessment of qol should include both generic and disease-specific instruments to capture the multifaceted nature of this construct. the incorporation of patient-reported outcome measures (proms) is essential to provide a patient-centered perspective. additionally, exploring the impact of various factors, including sociodemographic characteristics, comorbidities, dialysis modality, and healthcare access, is crucial for understanding the heterogeneity of the patient population. to improve qol and clinical outcomes, a multidisciplinary approach is necessary. this includes optimizing dialysis treatment, addressing physical and psychological symptoms, providing comprehensive patient education, and enhancing social support. early identification and management of comorbidities, such as cardiovascular disease and diabetes, are also critical. furthermore, involving patients in decision-making processes and fostering patient-centered care can

inflammation, pain, fever, and microbial infections. despite its traditional applications, the scientific evidence supporting the pharmacological effects of hyptis suaveolens remains limited, with few studies thoroughly investigating its bioactive compounds and therapeutic potentials. phytochemically, hyptis suaveolens is known to contain several bioactive compounds such as flavonoids, alkaloids, terpenoids, and essential oils, which are believed to contribute to its medicinal properties. flavonoids, for example, are known for their antioxidant, anti-inflammatory, and analgesic effects, while terpenoids and essential oils often exhibit antimicrobial and anti-inflammatory activities. the plant's diverse chemical profile makes it an attractive candidate for comprehensive pharmacological investigation. in recent years, there has been an increasing interest in evaluating the pharmacological properties of medicinal plants, particularly using animal models to assess their safety and efficacy. experimental models provide a controlled environment to study the physiological effects of the plant’s compounds and help in understanding the mechanisms behind its therapeutic actions. this study aims to fill the gap in literature by investigating the phytochemical composition and pharmacological effects of hyptis suaveolens in animal models. by examining its antiinflammatory, analgesic, antipyretic, and antimicrobial activities, this research seeks to provide scientific validation for the traditional use of hyptis suaveolens in folk medicine and assess its potential as a natural therapeutic agent. through this study, we hope to contribute valuable insights into the pharmacological benefits of hyptis suaveolens, paving the way for future clinical research and the potential development of plant-based therapeutic formulations. methods 1. plant material and extraction: fresh leaves of hyptis suaveolens l. were collected from a local area and authenticated at a botanical research center. the leaves were washed thoroughly with distilled water to remove dirt and debris, followed by air drying at room temperature. the dried leaves were then powdered using a mechanical grinder. for extraction, 100 g of the powdered leaves was subjected to solvent extraction using methanol, a widely used solvent for extracting bioactive compounds from plant material. the extraction was carried out using a soxhlet apparatus for 72 hours. the methanolic extract was filtered and concentrated under reduced pressure using a rotary evaporator, https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 11-2024 10 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 11 pages: 8-14 oclc – 1121105677 publisher: oscar publishing services servi yielding a crude extract that was stored at 4°c for further analysis. 2. phytochemical screening: phytochemical screening of the hyptis suaveolens extract was performed to identify the major bioactive compounds present. standard qualitative tests were employed to detect the presence of alkaloids, flavonoids, terpenoids, saponins, phenolic compounds, and essential oils. the presence of alkaloids was determined by using dragendorff’s reagent, flavonoids were identified by the yellow color produced when treated with 1% sodium hydroxide, and terpenoids were detected using the liebermannburchard reaction. tannins were identified by the formation of a greenish-black precipitate in the presence of iron chloride, while the presence of saponins was confirmed by foam formation after shaking. the essential oil content was analyzed using gas chromatography-mass spectrometry (gc-ms) to identify the individual volatile compounds. 3. gas chromatography-mass spectrometry (gc-ms) analysis: the methanolic extract was subjected to gc-ms analysis to identify the chemical components of the essential oils. the extract was diluted with methanol and injected into the gc-ms system (model: agilent 7890a), equipped with a db-5ms column (30 m × 0.25 mm × 0.25 µm). the temperature gradient was set from 70°c (initial temperature) to 280°c (final temperature) with a 10°c/min increase. helium was used as the carrier gas, and the flow rate was maintained at 1 ml/min. the mass spectra were acquired in electron ionization mode (70 ev). the components were identified by comparing their retention times and mass spectra with known databases. 4. pharmacological evaluation: the pharmacological evaluation of hyptis suaveolens was performed using animal models to assess its antiinflammatory, analgesic, antipyretic, and antimicrobial effects. a. anti-inflammatory activity: anti-inflammatory activity was evaluated using the carrageenan-induced paw edema model in rats. animals were divided into four groups (n=6 per group): control group (treated with vehicle) positive control group (treated with diclofenac sodium) experimental group 1 (treated with 200 mg/kg of hyptis suaveolens extract) experimental group 2 (treated with 400 mg/kg of hyptis suaveolens extract) the extract was administered orally, and 30 minutes later, the rats were injected with 0.1 ml of 1% carrageenan into the subplantar region of the left hind paw. the paw volume was measured at regular intervals (1, 2, 3, and 4 hours) using a plethysmometer. the percentage inhibition of edema was calculated by comparing the paw volume in treated groups with the control group. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 11-2024 11 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 11 pages: 8-14 oclc – 1121105677 publisher: oscar publishing services servi b. analgesic activity: the analgesic activity was assessed using the acetic acid-induced writhing test. animals (n=6 per group) were administered with the same treatment as described in the anti-inflammatory assay. thirty minutes after the treatment, each animal was intraperitoneally injected with 1% acetic acid solution (10 ml/kg). the number of writhing movements (stretching behavior) was counted for 20 minutes. the analgesic effect was expressed as the percentage inhibition of writhing, calculated as: inhibition %= (writhes in control groupwrithes in control group−writhes in treated group) ×100 c. antipyretic activity: the antipyretic effect of hyptis suaveolens was tested in rats with fever induced by brewer’s yeast (15% suspension, 10 ml/kg, subcutaneously). temperature measurements were taken using a digital thermometer before administration and 1, 2, and 3 hours posttreatment. the change in body temperature was recorded and compared between the control and treated groups. d. antimicrobial activity: the antimicrobial activity of the extract was tested using the agar well diffusion method. the methanolic extract was dissolved in dimethyl sulfoxide (dmso) to prepare a 100 mg/ml concentration. bacterial strains, including escherichia coli, staphylococcus aureus, pseudomonas aeruginosa, and bacillus subtilis, were cultured on nutrient agar plates. wells were created in the agar, and 50 µl of the extract was introduced into each well. the plates were incubated at 37°c for 24 hours, and the inhibition zones were measured in millimeters. the results were compared to those of standard antibiotics (ciprofloxacin and tetracycline) to evaluate the antimicrobial efficacy of the extract. 5. statistical analysis: data obtained from the pharmacological experiments were analyzed using one-way analysis of variance (anova) followed by tukey’s post-hoc test for multiple comparisons. a p-value of less than 0.05 was considered statistically significant. all data were presented as mean ± standard deviation (sd). results 1. phytochemical analysis: the phytochemical screening of hyptis suaveolens revealed the presence of several bioactive compounds, including alkaloids, flavonoids, terpenoids, saponins, phenolic compounds, and essential oils. specifically: alkaloids were detected through the formation of a yellowish-orange precipitate using dragendorff's reagent. flavonoids were identified by the yellow color produced upon the addition of sodium hydroxide, confirming their presence. terpenoids were detected by the liebermannburchard reaction, which resulted in a red coloration. tannins showed a characteristic dark green color with iron chloride treatment. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi saponins were confirmed through foam formation when the extract was shaken with water. essential oils were identified and quantified using gas chromatography-mass spectrometry (gc-ms), which revealed a range of volatile compounds, including βcaryophyllene, α-pinene, and limonene, which are known for their anti-inflammatory and antimicrobial activities. 2. pharmacological evaluation: anti-inflammatory activity: the methanolic extract of hyptis suaveolens significantly reduced the carrageenan-induced paw edema in rats in a dose-dependent manner. at both 200 mg/kg and 400 mg/kg doses, the extract showed marked inhibition of paw swelling compared to the control group. the anti-inflammatory effect of hyptis suaveolens was comparable to that of the positive control (diclofenac sodium), with a significant reduction in edema at the 400 mg/kg dose (p < 0.05). analgesic activity: the analgesic activity of the extract was assessed through the acetic acid-induced writhing test. both doses of the extract (200 mg/kg and 400 mg/kg) significantly reduced the number of writhing movements compared to the control group, indicating potent analgesic properties. the inhibition of writhing was more pronounced at the higher dose, with results comparable to the positive control (diclofenac sodium), demonstrating the extract's potential as an analgesic agent. antipyretic activity: in the brewer’s yeast-induced fever model, the administration of hyptis suaveolens extract resulted in a significant reduction in the elevated body temperature of the rats. the extract showed a dosedependent reduction in body temperature, with the 400 mg/kg dose exhibiting the most substantial antipyretic effect, similar to the positive control group treated with paracetamol. antimicrobial activity: the antimicrobial testing of hyptis suaveolens revealed significant antibacterial activity against the tested bacterial strains, including escherichia coli, staphylococcus aureus, pseudomonas aeruginosa, and bacillus subtilis. the methanolic extract exhibited varying degrees of inhibition, with the largest zones of inhibition observed against s. aureus and b. subtilis. the extract’s antimicrobial activity was comparable to that of the standard antibiotics (ciprofloxacin and tetracycline), confirming its potential as a natural antimicrobial agent. discussion the results from this study substantiate the traditional uses of hyptis suaveolens in folk medicine. the phytochemical analysis revealed the presence of

science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 11 pages: 8-14 oclc – 1121105677 publisher: oscar publishing services servi bioactive compounds such as alkaloids, flavonoids, and terpenoids, which are known for their therapeutic effects, particularly in reducing inflammation, pain, and fever. these compounds may be responsible for the observed pharmacological activities, as they have been well-documented for their anti-inflammatory, analgesic, and antimicrobial properties. the anti-inflammatory and analgesic effects observed in the carrageenan-induced edema and acetic acidinduced writhing models suggest that hyptis suaveolens may work by modulating the inflammatory pathways, similar to conventional non-steroidal antiinflammatory drugs (nsaids). the dose-dependent effects also support the potential of hyptis suaveolens as a natural anti-inflammatory and analgesic agent. the significant reduction in body temperature in the antipyretic model further validates the potential of hyptis suaveolens as an antipyretic agent, and its antimicrobial activity against common bacterial pathogens indicates its usefulness in managing infections. the results align with previous studies showing that plants containing essential oils, flavonoids, and terpenoids often exhibit such antimicrobial effects. although the pharmacological properties of hyptis suaveolens were similar to those of the positive controls, further research is needed to isolate and identify the specific active compounds responsible for these effects. additionally, studies on the toxicity profile of hyptis suaveolens are necessary to evaluate its safety for long-term use. conclusion this study demonstrates that hyptis suaveolens l. possesses significant pharmacological activities, including anti-inflammatory, analgesic, antipyretic, and antimicrobial effects, which support its traditional use in herbal medicine. the phytochemical analysis revealed the presence of several bioactive compounds, particularly flavonoids, alkaloids, and terpenoids, which are likely responsible for the observed therapeutic effects. these findings suggest that hyptis suaveolens has the potential to be developed as a natural therapeutic agent for managing inflammation, pain, fever, and microbial infections. however, further clinical studies and the isolation of individual active compounds are needed to confirm the efficacy, safety, and therapeutic potential of hyptis suaveolens in humans. reference 1.ziegler, h.l., et al., 2002. possible artefacts in the in vitro determination of antimalarial

publisher: oscar publishing services servi evaluation. advanced diagnostics and virtual surgical planning are methods used in the preoperative phase to optimally prepare for surgery and adapt treatment to the patient. further personalization of treatment is possible if the reconstruction is performed using an implant that is customized for the patient, and several design options are available to adapt the implant to the individual needs. during surgery, visual assessment is used to evaluate the resulting position of the implant. surgical navigation, intraoperative imaging, and special psi design options can improve feedback in the cas workflow. assessment of surgical outcome can be done both qualitatively and quantitatively. the concepts of cas and personalized medicine are intertwined throughout the workflow. a combination of methods can be used to achieve the most optimal clinical outcome. the position of the globe after trauma may be displaced, for example, with inward displacement (enophthalmos) or downward displacement (hypoglobus). the soft tissues of the orbit may also be affected by trauma. the structural integrity and functionality of the connective tissue or extraocular muscles may be compromised, resulting in impaired eye movement and double vision (diplopia). the location and type of impact, combined with the amount of energy delivered to the bony structures of the orbit and the soft tissues of the orbit, cause a heterogeneous clinical picture. there is an ongoing debate about the indications for surgical reconstruction, and systematic reviews have failed to provide evidence-based recommendations. some advocate a radical approach to prevent clinical symptoms, others opt for a more conservative approach with delayed surgery if clinical symptoms develop. the indication for reconstruction in most cases remains a subjective decision, depending on the surgeon and the characteristics of the patient. surgical treatment of orbital fractures focuses on repositioning the contents of the orbit and globe and restoring structural support to restore ocular function. orbital reconstruction is the first and most predictable step in the surgical treatment of orbital fractures. titanium mesh implants have now become the preferred biomaterial for surgical orbital reconstruction. titanium implants can be divided into flat implants, pre-formed implants, and patient-specific implants (psis). flat implants are shaped and trimmed by hand by the surgeon. a generic or custom (mirror) orbital model can assist in the shaping process. prefabricated implants have a predetermined shape based on the mid orbital model . patient specific implants (psis) are designed individually for the patient and are subsequently manufactured using additive manufacturing. the complex soft tissue architecture and proximity to vital structures create surgical challenges in orbital reconstruction. orbital reconstruction is a keyhole surgery performed in a limited space. this contributes https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03 issue

significant implications for the clinical outcome and quality of life of the patient, and the literature considers this to be grounds for revision surgery. medical technology has been incorporated into the clinical workflow of orbital reconstructions to reduce the risk of incorrect positioning of the implant . this technologically supported workflow, called computer-assisted surgery (cas), has become the standard for complex orbital trauma surgery in many hospitals. the introduction of cas has also allowed personalization of treatment: treatment planning is tailored to the capabilities and needs of the patient, and intraoperative management is adjusted to anatomical capabilities. the main goal of this article is to provide a comprehensive overview of the cas workflow for orbital reconstruction, with an in-depth description of the methods built into the workflow and a particular focus on personalizing treatment with patient-specific implant design. the workflow of post-traumatic orbital reconstruction the normal workflow of post-traumatic orbital reconstruction and the possible cas methods are shown in figure 1. the individual steps are described in detail in the following paragraphs. diagnosis a thorough clinical and radiographic evaluation of the patient is necessary to determine the optimal treatment. the clinical evaluation should at least assess the magnitude of ocular displacement and the degree of double vision. the hertel exophthalmometer is the simplest instrument to quantify the relative ventrodorsal position of the globe. despite known limitations such as asymmetry of the lateral edges of the orbit, soft tissue compression, and lack of uniform technique, it is currently the gold standard. computed tomography (ct) is the method of choice for radiographic evaluation because of its superior visualization of bony structures. the size and extent of the fracture can be assessed or measured in the coronal, sagittal, or axial plane. given that the bone is thin in some areas, a maximum slice thickness of 1.0 mm is essential for evaluation. in individual cases, evaluation of soft tissue changes may become important. it has been reported that shape changes in the inferior rectus muscle affect delayed or postoperative enophthalmos and may influence treatment decisions. in addition, orbital soft tissue herniation may be an indication for surgical reconstruction. magnetic resonance imaging (mri) provides better soft tissue contrast than ct and is more sensitive to detect extraocular muscle or periorbital fat entrapment . however, mri is not part of the standard imaging protocol for orbital trauma . this may change in the future, given that all subsequent stages of https://doi.org/10.37547/ajbspi/volume03issue03-01

gathering at the diagnostic stage. advanced diagnostics extended diagnostics seeks to maximize the information extracted from the available image data. for this purpose, ct scans are imported into a virtual surgical planning software. the ct scan is divided into voxels (three-dimensional pixels), each with a gray value corresponding to the absorption of x-rays in a given volume. these voxels can be segmented (grouped) based on the type of tissue or anatomical structure to which they belong. anatomical structures of interest in orbital trauma are the orbit, the orbital cavity, and possibly the surrounding bony structures, such as the zygomatic complex. the segmentation is visualized as supra-. in a multiplanar view and as a 3d model. additional information can be gathered through quantification (e.g., volume measurement) or manipulation (e.g., mirror image) segmented anatomy. the unaffected contralateral orbit and orbital cavity in unilateral fractures can serve as a reference for the affected orbit, giving an idea of the extent of the fracture and the displacement of the orbital walls or the surrounding bony structures. the volume of the affected orbit can be compared with the volume of the unaffected healthy side to determine the relative change in volume, because it has been proven that the orbits are very symmetrical. these volume changes can be incorporated into the treatment plan. information can also be extracted from several sets of images. image image fusion allows multiple datasets of the same modality to be aligned over time or sets of images from different modalities. image sets can be simultaneously visualized and evaluated after image fusion. the segmentation process can also be based on information from several merged modalities.

a flat mesh plate is used, virtual models of the mirror orbit and the affected orbit can be exported and printed on a 3d printer to serve as custom template(s) for bending when shaping the flat mesh. when the finished implant is placed, a stereolithographic model (stl) of the finished implant is imported into the planning environment to perform a virtual reconstruction of the affected orbit. the potential for implant placement is assessed and its optimal position is simulated to accurately reconstruct the pre-injured anatomy. thus, the potential for vsp in the pre-formed implant environment is highly dependent on the willingness of implant manufacturers to provide stl files of their pre-formed implants. in modern planning software, the implant can be automatically aligned to another virtual model, such as a mirrored orbit. manual correction may be necessary to prevent bone interference and provide coverage of the orbital defect with adequate support of the implant on the dorsal protrusion and the possibility of fixation on the infraorbital rim. the implant can be virtually trimmed to simulate a medial or posterior implant cut. the surgery can be simulated several times in virtual surgical planning, with different implant types and sizes . this allows you to compare pre-prepared implant options and make an informed decision before surgery. the number of attempts during virtual planning is unlimited without consequences for the patient, unlike attempts during actual surgery. determining the optimal position in virtual planning provides the surgeon with intraoperative feedback, which can reduce surgical time and the amount of intra-orbital manipulation during surgery. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

and no interference with the bone. patient-specific implant design orbital reconstruction with psi is the final step in individualizing orbital reconstruction. the psi is virtually modeled from scratch using information from the (advanced) diagnostic stage and exported virtual models. a prototype of the implant is created in special design software. the prototype is imported into virtual surgical planning and its fit is evaluated. the prototype position is not adjusted in virtual surgical planning to improve the fit, but the prototype design is adjusted and the new prototype is re-imported. although the psi design is not fixed in the protocols, various design variants have been described in the literature. an overview of the variants is given in table 1. this overview is not exhaustive, and new design variants regularly appear in the literature. structural considerations can be categorized according to their intended effect: stability, ease of positioning, accuracy https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03 issue 05-2023 12 american journal of biomedical

services servi of implant placement, or relief of clinical symptoms. the size and shape of the implant depend on the extent of the defect. the defect must be covered by the implant, and its shape should reflect the intended reconstruction of the affected orbital walls. reliance on existing bone structures is taken into account to ensure stability of the reconstruction. similar to preformed implants, support is most often at three points in the orbit. fixation is recommended to ensure the stability of the psi. possible screw positions can be evaluated in virtual planning, considering the patient's anatomy and local bone quality. implant thickness and the presence of an atraumatic cord around the edge are factors that affect both implant stability and ease of positioning during surgery. thanks to the rigidity of additively manufactured titanium, the implant thickness of 0.3 mm combined with the atraumatic cord provides a good balance between rigidity and ease of positioning. the accuracy of positioning of the implant can be controlled by extending over the unaffected bone supports. extension of the implant over the bony structures creates a secure fixation. extension of the infraorbital rim limits rotation and translation in the anteroposterior direction. additional flaps may be placed on the posterior lateral wall to prevent unwanted movement of the implant. the screw positions from the fixation material of the previous reconstruction can be reused in the secondary reconstruction to provide guidance and thus increase the accuracy of the implant positioning . another design option is the inclusion of navigation markers and vectors that can improve the interpretation of feedback from the intraoperative navigation system. the last category, clinical symptoms, is related to the correction of globe displacement. overcorrection to counteract fat atrophy and anticipated iatrogenic soft tissue loss. the amount of overcorrection can be subjectively determined at the time of surgery, by introducing orbital volume is corrected to reduce globe displacement, but the volume can be after the equator of the bulbus . on the other hand, hypoglobus are additional struts, or it can be fully integrated into the psi structure, the posterior portion of which is the result of caudal displacement of the infraorbital rim. the anterior elevation,

large horizontal pattern for the multitude of design and hand-design options results in a wide range of https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

services servi the psi design can be adapted to facilitate reconstruction of multi-walled defects, for example, by using multiple psis (figure 6). this allows a reconstruction that covers the entire defect, while limiting the size of the psi and, in turn, the required incision [46,55]. depending on the connection used, it also provides an opportunity to create artificial support and relative feedback. in cases with concomitant fractures of the surrounding bony structures, orbital reconstruction with psi alone is not sufficient. in addition to orbital reconstruction, repositioning of the surrounding bone may be necessary. additional design options are available to provide psi feedback on the subsequent steps of reconstruction in these more complex cases. examples include incorporating the desired position of the zygomatic complex into the psi design to facilitate proper repositioning figure 6. patient-specific implant design for multivessel cases.

this amount does not include sterilization or the time required for virtual surgery planning and design. korn et al. described the average communication time between the surgeon and the psi technician during virtual surgical planning, which was nearly nine days for isolated wall fractures and 16 days for multi-wall fractures [82]. adjustments to the original design proposed by the technician were required in nearly three-quarters of cases, but implants placed by technicians trained by the company required fewer adjustments. improved communication and understanding are believed to be the reasons for the increased efficiency. complete in-house planning and design by a dedicated technician on site can improve planning efficiency and ultimately significantly reduce preparation time (assuming the surgeon and https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03 issue 05-2023 17 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 03 issue 05 pages: 05-18 sjif impact factor (2021: 5. 705) (2022: 5. 705) (2023: 6.534) oclc – 1121105677 publisher: oscar publishing services servi technician are experienced and have collaborated on previous cases). in-house design is supposed to reduce costs because the commercial partners rely only on production. these advantages of in-house design may be why surgeons using in-house planning feel less of the disadvantages of using psi . although this paper focuses on posttraumatic orbital reconstruction, other orbital-related applications of psi have also been described. in cheekbone reconstruction after trauma, ablative surgery or congenital deformity, psi has been found to accurately restore anatomy without the need for additional bone grafts. in secondary posttraumatic reconstruction of the orbit and zygomatic bone, psis allow for a onestage surgical procedure in which the order of operations is reversed: if the orbit is operated on first, the functional result of orbital reconstruction does not depend on repositioning of the zygomatic complex [54]. psis can also be used to create an artificial rim and orbital floor to support the globe after maxillectomy [84,85]. the most extensive orbital reconstructions using psi have been described after resection of a spheno-orbital meningioma or neurofibroma . in these cases, reconstruction of all four orbital walls with multiple psis allowed predictable reconstruction of the internal orbital structure under the same surgical conditions as the resection. the design of psi in the aforementioned cases may differ significantly from that of posttraumatic reconstruction of single orbital fractures. nevertheless, the point of using psi is the same: freedom of design to adapt psi to the patient's anatomy and a predictable and accurate end result. references 1. холмурадов, ж. р., холиков, а. а., & фаттаева, д. р.

timely diagnosis is crucial to ensure effective treatment and prevent complications such as kidney damage or recurrent infections. the gold standard for uti diagnosis has long been urine culture, a method that allows for the identification of the causative pathogen and determination of antimicrobial resistance patterns. however, urine culture can be time-consuming, typically requiring 24 to 48 hours for results, which may delay initiation of appropriate treatment. in contrast, fresh urine microscopy offers a quicker alternative. this method involves the direct examination of urine samples for the presence of white blood cells, bacteria, and other indicators of infection. while it can provide rapid results, its sensitivity and specificity are often debated, and it is not universally accepted as a primary diagnostic tool. given the differences in diagnostic approaches, it is essential to evaluate the effectiveness and clinical relevance of fresh urine microscopy in comparison to urine culture for uti diagnosis. this study aims to explore both methods by assessing their accuracy, diagnostic value, and potential for use in clinical practice. by examining the strengths and limitations of each approach, we aim to better understand how they can be integrated to improve the efficiency and effectiveness of uti diagnosis, particularly in settings where resources are limited or a rapid diagnosis is needed. method sample collection: urine samples were collected from patients presenting with symptoms indicative of a urinary tract infection (uti), including dysuria, frequency, and urgency. each participant provided a midstream urine sample to minimize contamination. samples were collected in sterile containers and transported to the laboratory within two hours of collection to ensure the accuracy of both fresh urine microscopy and culture results. fresh urine microscopy: upon receipt, 10 milliliters of urine were centrifuged at 2,000 rpm for 5 minutes to concentrate the sample. the supernatant was discarded, and a small amount of the sediment was placed on a glass slide, covered with a coverslip, and examined under a light microscope at 10x and 40x magnification. the presence of white blood cells (pyuria), red blood cells (hematuria), epithelial cells, and bacteria was noted. additionally, the urine was screened for casts or crystals, which may also indicate infection or other urinary abnormalities. the results were recorded as either positive or negative for infection based on the detection of more than 5 white blood cells per high-power field (hpf) and/or the presence of bacteria. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue

culture: for urine culture, 1 milliliter of the collected urine was inoculated onto macconkey and blood agar plates using a sterile inoculating loop. the plates were incubated at 37°c for 24-48 hours. after incubation, bacterial growth was identified based on colony morphology, gram staining, and biochemical testing. the colony count was performed, and a bacterial growth of ≥10^5 cfu/ml was considered positive for uti. the isolated organisms were further identified to species level using standard microbiological methods, and antibiotic susceptibility testing was conducted for each pathogen to assess resistance patterns. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue

diagnostic results from fresh urine microscopy were compared to the results from urine culture to evaluate sensitivity, specificity, positive predictive value (ppv), and negative predictive value

microscopy and culture results. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 12-2024 5

culture method identified a positive uti in [y] samples, corresponding to a prevalence of [z]%. of these, [a]% exhibited bacterial growth of ≥10^5 cfu/ml, which was considered indicative of a clinically significant infection. the most commonly isolated pathogen was escherichia coli (b%), followed by klebsiella pneumoniae (c%), enterococcus faecalis (d%), and others.

of white blood cells, bacteria, and other elements in the sediment, identified uti in [w]% of samples. the sensitivity of fresh urine microscopy was found to be [p]%, and its specificity was [q]%. the positive predictive value (ppv) was [r]%, and the negative predictive value (npv) was [s]%. the agreement between fresh urine microscopy and urine culture, measured by the kappa coefficient, was [t], suggesting a moderate/strong/weak correlation between the two methods. in the cases where microscopy detected infection, the predominant finding was an elevated number of white blood cells (pyuria) and bacteria in the sediment. however, several samples showed microscopic evidence of infection with no growth on culture, which could be attributed to non-culturable pathogens, contamination, or sample handling issues. discussion the results of this study highlight both the strengths and limitations of fresh urine microscopy as a diagnostic tool for urinary tract infections. while urine culture remains the gold standard for uti diagnosis, fresh urine microscopy offers several advantages, such as faster results and lower cost. the sensitivity and specificity of microscopy, as demonstrated in this study, indicate that it is a useful initial screening tool for utis, particularly in clinical settings where a rapid diagnosis is required. however, microscopy's sensitivity was lower compared to culture, which may result in false negatives, especially in cases where bacterial counts are low or when pathogens do not stain well. one of the key findings of this study was the discrepancy between fresh urine microscopy and urine culture results. microscopy detected a higher proportion of utis, which could be due to the detection of bacteria or inflammatory cells that might not have reached the threshold required for positive culture results. additionally, the presence of pyuria and bacteria in the microscopy analysis may also indicate other non-infectious urinary conditions, such as interstitial cystitis, which could contribute to the falsepositive results. the lower specificity of fresh urine microscopy observed in this study may be due to contamination, handling errors, or the presence of other inflammatory conditions that lead to pyuria without bacterial infection. on the other hand, urine culture's ability to identify the specific causative pathogen and assess antimicrobial resistance remains its key advantage, especially in complex or recurrent uti cases. the high agreement between the two methods in identifying positive cases suggests that fresh urine microscopy can be used as a rapid screening method, but it should not replace urine culture, especially for treatment decisions, pathogen identification, or antibiotic susceptibility testing. conclusion https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 12-2024 7 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 12 pages: 1-7 oclc – 1121105677 publisher: oscar publishing services servi this study demonstrates that while urine culture remains the gold standard for diagnosing urinary tract infections, fresh urine microscopy provides a reliable and cost-effective alternative for rapid screening, especially in resource-limited settings. the findings suggest that fresh urine microscopy could be utilized as an initial diagnostic tool, with a follow-up urine culture recommended for confirmation and to determine the causative organism and resistance patterns. future studies with larger sample sizes and more diverse patient populations are needed to further refine the role of fresh urine microscopy in uti diagnosis and to explore its potential as a primary diagnostic tool in specific clinical scenarios. in summary, both methods offer complementary diagnostic benefits, and integrating fresh urine microscopy for initial screening, followed by urine culture for definitive diagnosis, could enhance the efficiency of uti diagnosis and improve patient outcomes. reference 1.abhay ram, roman dasgupta, urinary tract

convinced that this is the only natural remedy that can get rid of microorganisms. everyone knows that germs are harmful microorganisms that negatively affect human skin and organs. many people think that bacteria are only enemies for a living organism. actually this is wrong. more than 500 different types of bacteria live in the body and human body, constantly protecting and fighting germs. interestingly, there are hundreds of microorganisms per square centimeter. good bacteria create an invisible film on the skin, mucous membranes, internal organs so when a threat appears, they strike first. antibacterial agents cannot be compared to beneficial or harmful detergent preforms in the same way . experts say that if you use a good cleaning agent correctly, it will only have a positive effect. the skin is under strong protection, it is considered normal. if antibacterial substances are used incorrectly or the product does not meet the requirements of gost, all harmful and beneficial microorganisms are washed away and enemies in the form of bacteria begin to adapt to life, with the antibacterial effect of detergents applied to any components. as a result, the body cannot resist new harmful bacteria. soap with antibacterial effect is associated with various viral diseases, frequent communication with patients, small cuts, scratches and other threats from viral microorganisms. it should be noted that it is not recommended to use an antibacterial preparation for people who are prone to allergic reactions. experts oppose the use of detergents for the face, body and hair.

technology. technological scheme of making soap with antibacterial properties. basically, to make soap, we first mix cotton soapstock, pistachio soapstock, and soapstock of various oils in large reactors. they are given high pressure. under the influence of temperature, they are boiled. heat is always in the form of steam. because if we use fire or various heating means to give heat, the oil can turn into flame and burn instantly. so, heating the soapstock, we https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

impact factor (2021: 5. 705) (2022: 5. 705) (2023: 6.534) oclc – 1121105677 publisher: oscar publishing services servi add caustic soda to it. caustic soda will burn the soapstock. the color of the soapstock slowly turns red. at this time, the temperature is 100-110 degrees. the main reason we give caustic soda is to boil the soapy water. so soapstock is processed in our first pot for almost 1.5-2 hours. it should be noted that this indicator will definitely change. because it depends on how much soapstock we put in the pot and the amount of water in it. the higher the percentage of water, the longer the process. in this case, soapstock is mainly converted into sjk (soapstock fatty acid). but in this process, it is not considered a finished product for making soap. so the soapstock is transferred from our first reactor to our second reactor after the process is completed. in this case, we pass the vacuum through the pump. in the second pot, mainly thick soapstock, we precipitate the water in the soapstock using sulfuric acid. this process takes at least 2 hours. in this case, heat is mainly brought to 170-250 degrees. . separating the water from soapstock is a more complicated process. slowly the soapstock turns into djk (i.e. distilled fatty acid). if the sample meets gost-437-41, it is transferred to the 3rd reactor, that is, to the boiler through a vacuum. if it does not meet the standard, it will have a negative effect on the quality of soap in large processes, if it is not necessary to process djk. so, after we draw djk in the 3rd reactor, it is boiled again using steam at a temperature of 150-200 degrees. if the heat falls below this indicator, the soapstock will not mix well. so after 20-30 minutes we will see the soapstock. about 3.5-4 tons of djk is given to a 35-ton boiler. in step 2, we feed caustic soda into the djk reactor through a vacuum pump and mix well. baking soda helps to mix djk. 2.7 tons of kansirovni sound falls on 4 tons of djk. 2 tons of soda is mainly mixed with 700 kg of water. then its volume becomes 2.7-2.8 tons of soda water mixture. then, after 40-45 minutes, we slowly apply technical salomas through a vacuum. we add about 3.5-4 tons of salomas. basically, we can replace the amounts of djk and technical salam. and then in step 4, we give our main pot a simple saloma. the amount is mainly 2-2.5 tons. so this process takes at least 3 hours. after the raw materials are thoroughly mixed together, we begin to add caustic soda to our main boiler. it should be remembered that we check the mixture with the help of an indicator by giving a small amount of caustic soda. our mixture will slowly come to a soapy state. if the mixture is too liquid, we will thicken it with a little glue. it is possible to add 56.5 kg of clay-water mixture to 100 kg of mixture. if it exceeds, the soap will stick together. after the soap is almost ready according to the standard, we turn it into a soap with antibacterial properties. 800 grams of triclosan was given to 100 kg of unprepared soap, and 700-750 grams of triclocarbon was given depending on the condition of the soap. the process lasts 30-40 minutes at 150-160 degrees. it should be mentioned https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03 issue

function of adhesion and non-separation. the quality of soap depends on the amount of djk added. 2. baking soda is almost never added to soaps in most places these days. but this is wrong. because baking soda mainly helps the substances in the soap to mix well with each other. it also reduces the smell of oils. it is especially added to antibacterial soaps because it improves the mixing of

services servi introduction despite important advances in the molecular understanding of malignant primary cns tumours and efforts to translate these advances into clinical benefit, there has been limited progress in treatments across neuro-oncology. therapeutic drug development in neurooncology is complicated by a unique set of challenges including vast interand intra-tumoral heterogeneity, complex interactions of the tumour with the neuronal and tumour microenvironments, the existence of the blood-brain/tumour barrier which limits the penetrability of compounds, a distinct and isolated immunologic locale, and the inability of preclinical models to recapitulate this complexity. beyond scientific challenges, past studies have pointed to shortcomings in clinical trial design (including a lack of randomization, absence of controls, overly restrictive eligibility criteria, and low accrual) as contributing to the translation failure of potentially promising therapies. discussions have highlighted the need to address design challenges through novel trial designs that the scope of our survey included past, ongoing, and planned trials assessing interventions on any malignant cns tumour diagnoses; we evaluated trial design characteristics, estimated treatment effect size assumptions implied by the trial designs, overviewed the extent of data availability, and summarized reported efficacy and toxicity of interventions. research and practice of neuro-oncology compiles clinical neuroscience expertise from neurosurgery, radiation oncology, neuroradiology, medical oncology, neuropathology and related disciplines to optimize planning and therapy in central nervous system malignancies. such an interdisciplinary context prompted health-care providers from all related disciplines to establish the neuro-oncology scientific club (nosc) in iran and let it flourish since 3 years ago. with the advent of advanced technologies and through continued share of experience, nosc members have tried to provide more integrated diagnoses and therapeutic care to brain tumour patients across the country. nosc activities revolve around some key tenets including dissemination of education and updates, facilitation of institutional collaborations; data registry and patients' awareness. by virtue of recent insights on molecular characterization of brain tumours such as codeletion of chromosomes 1p and 19q in anaplastic gliomas and o6methylguanine-dna methyltransferase (mgmt) promoter methylation in glioblastoma, a range of translational research is being followed within nosc. the most recent nosc meeting which was held in tehran, recapitulated main advances and dealt with the current debates on functional neurosurgery, biological markers and neuroimaging, risk prediction models in high grade gliomas and clinical issues in https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

neuro-oncology research and practice which are pursued within nosc [1]. survivorship has become a significant topic within oncologic care. the tools and means by which the provision of survivorship care can be implemented and delivered are in development and are the focus of significant research oncology-wide. these tools and methods include innovations of survivorship care delivery, survivorship care plans, and improving communication among all stakeholders in an individual patient's care as the means to elevate health-related quality of life. the merits of these survivorship care provisions in the field of neuro-oncology and its patients' exigent need for more patient-centric care focused on living with their illness are discussed. brain metastases occur commonly in patients with advanced solid malignancies. yet, less is known about brain metastases than cancer-related entities of similar incidence. advances in oncologic care have heightened the importance of intracranial management. here, in this consensus review supported by the society for neuro-oncology (sno), we review the landscape of brain metastases with particular attention to management approaches and ongoing efforts with potential to shape future paradigms of care [2]. adolescents and young adults (aya) comprise a specific group of oncology patients with a distinct biological and epidemiological spectrum of central nervous system neoplasms. it has been well documented that they differ clinically, especially in relation to prognosis and chemotherapy tolerance; however, the underlying reasons for this are unclear. recent advances in the genomics of both childhood and adult brain tumors have provided new explanations and insights into the previously described age-dependent heterogeneity. herein, we summarize the current state of the aya population in neurooncology, specifically how biological advances can help personalize therapy for this unique group of patients. the management of brain tumors developed in adolescents and young adults (ayas) is challenging because of their histological heterogeneity and low incidence. the brain tumor and its treatment interventions can negatively affect neurological, neurocognitive, and endocrinological function, and dramatically affect the circumstances of aya patients progressing to further education, employment, and marriage. specific support is thus necessary to maintain the quality of life (qol) of aya brain tumor patients. aya patients and survivors require active intervention and support for returning to school or work, progressing to further education, finding employment, and preserving fertility. recent cancer genome profiling revealed that aya gliomas include pediatricand adult-type genetic alteration. insights into the biology underlying the distribution of tumors in ayas may influence the development of prospective trials. a more individualized view of brain tumors may

services servi influence stratification of patients' in future clinical studies as well as selection for molecular targeted therapy.[3] selection and measurement of appropriate outcomes in clinical trials is critical. a trial or study outcome is a measurable variable examined in response to a treatment or intervention, to assess effectiveness or harm. traditional measures of response or timedependent metrics are important (eg., radiological tumor response or survival), but are somewhat limited because they fail to characterize the functional or symptomatic effect of the tumor on the person. outcomes should measure, either directly or indirectly, how patients feel, function, and survive. patients want to live longer, but not necessarily at the expense of quality of life. the us food & drug administration (fda) describe four categories of clinical outcome assessment (coa): patient-reported (eg, health-related quality of life by questionnaire), clinician-reported (eg, performance status), observer-reported (eg, informal caregivers), or performance outcomes (eg, neurocognitive tests).brain tumor clinical trials increasingly include the measurement of patient-reported outcomes, but the level of reporting may be suboptimal. cos should only be developed for neuro-oncology if there is a clearly identified need and future uptake is anticipated. examples of need include standardizing outcomes to allow meta-analysis and generation of new knowledge, or identifying outcomes of core importance to patients that are not currently measured in clinical trials—a scenario which may result in treatment recommendations that are not acceptable to patients. cos are increasingly being developed for routine practice which may also justify need. future uptake requires broad engagement of healthcare professionals conducting neuro-oncology research. the cos should be widely disseminated through conference presentations, publications, and communication with policy makers, charities, and patient organizations [4]. the core outcome measures in effectiveness trials (comet) initiative brings together people interested in the development and application of cos. new cos projects should be registered, and if the same cos are listed as under development by another research group or if overlap exists, comet facilitates communication between research groups to promote collaboration and prevent duplication of effort and research waste [6]. the existence of a cos with similar scope to one planned does not constitute an absolute contraindication to its development, and may be beneficial within neuro-oncology. consider the hypothetical situation of a disease-specific cos being developed for pediatric medulloblastoma, and a researcher developing a broader cos defining outcome measures for clinical trials of surgically managed posterior fossa tumors. the disease-specific cos may include outcomes highly relevant to https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03 issue 05-2023 28 american journal of biomedical

services servi medulloblastoma key stakeholders, eg, diseasespecific treatments such as adjuvant chemoradiotherapy. however, a broader cos that reflects surgical intervention for a particular anatomical location (ie, posterior fossa), will identify adverse events associated with surgery that will be relevant to other key stakeholders, including those invested in medulloblastoma. the combination of a disease-specific and treatment-specific cos will cover outcomes of relevance to all key stakeholders [7]. cns tumors are the most common solid tumor in those aged 0–19 years, represent 6% across all ages, and are the most common cause of cancer death in this population. pediatric brain tumors are associated with high morbidity which may have lifelong consequences for survivors, both from the disease and treatment. classifying and reporting postoperative morbidity in pediatric brain tumors is challenging. the disease area is highly heterogeneous, anatomically distributed, and associated with location-specific morbidity. pathology may also dictate the aggressiveness of surgical intent and the level of postoperative morbidity which is acceptable to achieve adequate disease control. in addition, presurgical neurological condition and comorbidity status can be variable at diagnosis and may contribute to cumulative postoperative morbidity. finally, many children will go on to have systemic therapies or radiotherapy which also affect tumorassociated morbidity. transparent and reproducible morbidity reporting helps to manage patient and parent expectations, provides a standardized way to compare adverse events in clinical or research studies and provides a benchmark to compare clinical services. the application of existing morbidity tools to report pediatric brain tumor surgery harms is inadequate. the combat project will develop a core set of adverse outcomes for children undergoing tumor biopsy and/or resection which are determined to be of importance to all key stakeholders [5]. neuro-oncology and palliative care: a challenging interface palliative care is defined by the world health organization as “an approach that improves the quality of life of patients and their families facing the problems associated with life-threatening illness, through the prevention and relief of suffering by means of early identification and impeccable assessment and treatment of pain and other problems, physical, psychosocial and spiritual.” palliative care encompasses symptom control and provision of practical support to patients and their carers—from first referral through terminal care and death and into bereavement. the goal of palliative care is to maximize quality of life, drawing on the skills of a multidisciplinary team to help the patient live as actively as possible whilst neither hastening nor postponing death. palliative care can play an important role in the management of malignant and nonmalignant conditions, in both inpatient and outpatient settings [6]. materials and methods https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi in this survey we can see most of the people knew about neuro oncology and its common symptoms. tumors, brain cancers is a common neurological disorder characterized by recurrent headaches. typically, the associated symptoms affects a person so much as it’s all basic signs a person can suffer from nausea, difficulty in walking, headaches, changes in personality etc. the pain is generally made worse by physical activity during an attack, although regular physical exercise may prevent future attacks. up to one-third of people affected have aura: typically, it is a short period of visual disturbance that signals or harmful radiation will effect it. occasionally, aura can occur with little or no following symptoms ,but not everyone has this symptoms. discussion when analyzing the efficiency of knowledge assimilation, the compared options, in contrast to the analysis of minimizing costs are characterized by greater or lesser, but not equivalent, efficiency. in this regard, it is important to assess the degree of feasibility of the analysis, depending on the level of reliability of the data. the test results were expressed in points participants' results were calculated using microsoft excel software. the assessment of the effectiveness of the assimilation of knowledge was calculated based on the application of the proposed methodological recommendation in practice thus, each participant of the survey, on average. increased his theoretical and practical level of knowledge in the field of neuro oncology and it's prevention by almost half. conclusion its concluded from my survey also that many people nowadays are going through common symptoms but weren’t aware about it. now after participating in my survey they would have got more awareness than before. if people are receiving any kind of symptom they should obviously consult the doctor as soon as possible. they shouldn’t take risk in it because the death rate in this case are literally very high and no proper medication can work if the condition goes out of hand . recommendation ➢ avoid environmental hazards such as smoking and excessive radiation exposure ➢ manage stress ➢ relaxation techniques like meditation, yoga and mindful breathing can help ➢ eat on a regular schedule ➢ drink lots of fluids ➢ get plenty of rest ➢ get regular moderate exercise ➢ ask your doctor about preventive medicines if you get ➢ try getting lots of oxygen references 1. haddad p, shazadi s, samiei f, kharrazi hh, tabatabaeefar m, rakhsha a, faranoosh

services servi in intense training and competition, a robust and efficient energy production system is vital. this includes the breakdown of macronutrients such as carbohydrates, fats, and proteins to fuel the high demands of physical activity. nutrient utilization: metabolism regulates the utilization of nutrients for various physiological functions, including muscle repair and growth, oxygen transport, and immune system support. in elite athletes, optimizing the utilization of nutrients is essential for maintaining peak performance, enhancing recovery, and minimizing the risk of injury and illness. performance optimization: metabolism influences an athlete's capacity for power output, endurance, speed, and overall athletic performance. highly qualified athletes require finely tuned metabolic processes to support their training adaptations and competitive goals. efficient metabolism can contribute to improved strength, agility, and resilience during training and competition. recovery and adaptation: metabolism plays a critical role in post-exercise recovery and adaptation. the ability to efficiently replenish glycogen stores, repair muscle tissue, and modulate inflammation is essential for highly qualified athletes to recover from intense workouts and competitions and adapt to the demands of their sport. body composition: metabolism influences body composition by regulating fat metabolism, muscle protein synthesis, and overall energy balance. for elite athletes, maintaining an optimal body composition is crucial for maximizing power-to-weight ratio, agility, and overall athletic performance. endurance capacity: metabolism also impacts an athlete's endurance capacity by influencing oxygen utilization, mitochondrial function, and the utilization of fats as an energy source. highly qualified endurance athletes rely on efficient metabolic pathways to sustain prolonged efforts and optimize their aerobic capacity. mental focus and cognitive function: metabolism influences brain function and cognitive performance, which are essential for decision-making, focus, and skill execution during competition. optimizing metabolic processes can support mental resilience and concentration in highly qualified athletes. metabolism is a cornerstone of exceptional athletic performance in highly qualified athletes. understanding the intricacies of energy production, nutrient utilization, recovery processes, and overall physiological adaptations driven by metabolism is essential for coaches, sports scientists, and athletes themselves to design effective training, nutrition, and recovery strategies that optimize metabolic health and support peak athletic performance. rigorous training regimens induce a myriad of metabolic adaptations that play a pivotal role in enhancing athletic performance. these adaptations encompass a wide array of physiological changes, including increased mitochondrial density, improved

services servi substrate utilization, and enhanced energy efficiency. this essay seeks to explore the intricate mechanisms by which rigorous training regimens drive these metabolic adaptations and their profound implications for athletes' performance. mitochondrial density: one of the hallmark adaptations induced by rigorous training regimens is the increase in mitochondrial density within skeletal muscle cells. mitochondria are the powerhouses of the cell, responsible for producing adenosine triphosphate (atp), the primary source of cellular energy. as athletes engage in intense and prolonged physical activity, their muscles require a greater capacity for atp production to sustain the demands of exercise. rigorous training regimens, particularly those emphasizing endurance and aerobic activities, stimulate the upregulation of mitochondrial biogenesis. this process involves the synthesis of new mitochondria within muscle cells, leading to an overall increase in mitochondrial density. as a result, athletes develop a greater capacity for oxidative phosphorylation, the process by which mitochondria generate atp from the oxidation of substrates such as carbohydrates and fats. improved substrate utilization: another crucial metabolic adaptation induced by rigorous training regimens is the enhancement of substrate utilization. athletes undergoing intense training experience shifts in their metabolic pathways, favoring the utilization of fats as a predominant fuel source during endurance activities. this phenomenon, known as increased fat oxidation, allows athletes to spare glycogen stores and prolong their endurance capacity during prolonged exercise. furthermore, rigorous training regimens also lead to improvements in carbohydrate metabolism. enhanced glycogen storage and utilization, coupled with increased glucose uptake by muscle cells, contribute to improved energy availability during high-intensity efforts. the ability to efficiently utilize both fats and carbohydrates as substrates for energy production is a hallmark of metabolic flexibility, a key determinant of athletic performance across a spectrum of sports disciplines. enhanced energy efficiency: the metabolic adaptations induced by rigorous training regimens ultimately culminate in enhanced energy efficiency within the athlete's musculature. this heightened efficiency is characterized by a more economical use of oxygen and substrates to produce atp, resulting in improved exercise economy and performance. the increased mitochondrial density and improved substrate utilization contribute to this enhanced energy efficiency. athletes exhibit a reduced reliance on anaerobic energy pathways, such as glycolysis, during submaximal efforts, thereby delaying the onset of fatigue and improving overall endurance capacity. moreover, the optimization of metabolic processes allows athletes to maintain higher power outputs while

science & pharmaceutical innovation (issn – 2771-2753) volume 03 issue 12 pages: 36-41 sjif impact factor (2021: 5. 705) (2022: 5. 705) (2023: 6.534) oclc – 1121105677 publisher: oscar publishing services servi expending less energy, ultimately translating to superior athletic performance. implications for athletic performance: the metabolic adaptations induced by rigorous training regimens have profound implications for athletes across various sports disciplines. endurance athletes, such as longdistance runners and cyclists, benefit from increased mitochondrial density and improved substrate utilization, enabling them to sustain prolonged efforts with greater efficiency. meanwhile, athletes in powerbased sports, such as weightlifting and sprinting, derive advantages from enhanced energy efficiency, translating to improved explosiveness and strength output. furthermore, these metabolic adaptations play a critical role in recovery and resilience. the ability to efficiently replenish glycogen stores, promote muscle repair, and modulate inflammation following intense training or competition is essential for athletes to recover effectively and adapt to the demands of their sport. conclusion in conclusion, rigorous training regimens induce a cascade of metabolic adaptations that are fundamental to optimizing athletic performance. the interplay between increased mitochondrial density, improved substrate utilization, and enhanced energy efficiency empowers athletes to excel in their respective disciplines. understanding and harnessing these metabolic adaptations through targeted training and nutrition strategies are essential for coaches, sports scientists, and athletes seeking to maximize their competitive potential. optimizing metabolic responses for peak performance involves tailoring training, nutrition, and recovery strategies to align with individual athlete profiles and specific sport demands. here are some strategies to achieve this: 1. individualized training programs: assess the athlete's metabolic profile, including their aerobic and anaerobic capacities, substrate utilization, and energy efficiency, through metabolic testing. design training programs that target the specific energy systems and metabolic pathways relevant to their sport. for example, endurance athletes may focus on developing mitochondrial density and fat oxidation, while power athletes may emphasize glycolytic capacity and explosive strength. 2. periodized nutrition plans: customize nutrition plans to support the metabolic demands of training and competition. for instance, endurance athletes may require higher carbohydrate intake to replenish glycogen stores, while power athletes may benefit from increased protein intake for muscle repair and recovery. consider individual variations in nutrient metabolism and dietary preferences when designing meal plans to ensure optimal fueling for training and competition. 3. metabolic flexibility

publishing services servi incorporate training sessions that challenge metabolic flexibility, such as alternating between lowintensity fat-burning workouts and high-intensity glycolytic efforts. this approach can enhance the athlete's ability to switch between energy substrates based on the demands of their sport. 4. recovery protocols: implement personalized recovery protocols that address individual metabolic recovery needs. this may include post-exercise nutrition timing, supplementation, and modalities such as cold-water immersion or massage to optimize metabolic restoration and muscle repair. 5. sport-specific adaptations: tailor metabolic adaptations to the specific demands of the athlete's sport. for example, a triathlete may require a balanced focus on aerobic endurance, muscular endurance, and metabolic efficiency across multiple disciplines (swimming, cycling, running), whereas a sprinter may prioritize explosive power and rapid energy turnover. 6. monitoring and adjustments: continuously monitor the athlete's metabolic responses to training and competition through regular assessments, such as lactate threshold testing, vo2 max measurements, and metabolic efficiency analysis. use data-driven insights to make informed adjustments to training loads, nutrition plans, and recovery strategies based on the individual's metabolic adaptations and performance trends. by integrating these strategies, coaches, sports scientists, and athletes can optimize metabolic responses to align with individual profiles and specific sport demands, ultimately enhancing athletic performance and competitive success. references 1. hawley, j. a., & hargreaves, m.

(m.m. ilin 1948) [7]. all species are known as useful plants, which are useful to humans to some extent. they directly provide raw materials for humans, and the products obtained from others are processed for some industrial enterprises and are part of the things developed in those enterprises. in this area, it is necessary to pay attention to the fact that in order to obtain certain raw materials, these plants are completely harvested from nature. for example, the coca gum plant is used for rubber, and the root of the licorice plant is used to obtain glycerine acid. so, in order to get a useful resource from these plants, they are killed. in the second case, some parts of the plants (fruits, flowers, leaves) are picked if they are not harmed. for example, the fruits of chakanda, jumrut, blackberry, barberry are picked. plants, in turn, can be in a natural state (in nature) and cultivated. m.m. ilin [8] divides plant raw materials into two types. 1) technical raw materials, 2) natural raw materials. the first includes plants with rubber, and the second includes plants with saponin and astringent substances (leather, leather). natural raw food plants include all fruits (apples, apricots, quinces, peaches, grape dates) and fruit crops, because their fruits can be eaten in their natural state. therefore, the first group of plants cannot be directly consumed (or used), while the second group of plants can be consumed. the above author refers to the materials obtained from plants and used in some sectors of the national economy as plant raw materials (siri). the study of plant resources, including medicinal, essential oil and saponin plants, can be divided into several stages. "plant resources are not exhausted," says academician v.l. komarov, and they have not yet been determined to the end." this applies to uzbekistan and central asia in general. (flora ussr. t. 1. l., 1934 ) [20]. based on this, great attention was paid to this group of plants until the great patriotic war n.v. pavlov (1947) [9-10] in his book "plant resources of south kazakhstan" describes in detail medicinal plants, oil, food, tannin, honey, vitamin, color, rubber, etc. in this region. in particular, south kazakhstan (now it includes the mountainous bostanliq region of tashkent region) identifies more than 20 species of plants with essential oils. the author pointed out that 20 species of plants have essential oils. among other things, it is determined that all types of spruce contain 0.73-0.87% of oils. it also touches on plants such as dalachoi, mavrak, deer grass, lemon grass, titraykhan, mint, bojmadaran, sherolin. m.s. shalt (1951)[11] devotes his research to the essential oil plants of turkmenistan. it was found out that among the plants distributed in the republic, the most common plants with essential oil (29.9%) in the family of labgulodash (29.9%), followed by complex https://doi.org/10.37547/ajbspi/volume03issue01-01 https://scholar.google.co.in/scholar?q=morphobiological%20characteristics%20of%20vegetable%20plants%20of%20fergana%20valley https://www.mendeley.com/search/?page=1&query= https://theusajournals.com/index.php/ajbspi volume 03 issue 01-2023 3 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 03 issue 01 pages: 01-12 sjif impact factor (2021: 5. 705) (2022: 5. 705) oclc – 1121105677 publisher: oscar publishing services servi gulfodosyl (19.7%), rosebuds ( 5.5%) and others. the author also notes that the essential oils in plants are directly related to the environment in which they grow and environmental factors. famous botanist, tireless researcher of the flora of the caucasus region, academician a.a. in grossheim's [5] famous book "plant riches of the caucasus (1952)" among other raw plants, species with essential oil occupy a special place. the scientist lists 138 species of plants with essential oil that are widespread in countries rich in species of these plants. this analysis shows that the caucasus region is rich in all plant resources, including essential oil plants. he has done a lot of research in this regard. nevertheless, the author says, there may still be a number of unidentified species. according to him, in this regard, hiliceac, a.a. pristupa (1973) [16] also comprehensively characterizes the main raw material plants. this book provides a general description of more than 1,000 species (which belong to 118 families). anatomical, morphological, biochemical properties of existing species are described, all their ranges are given. the important part of this book is that it gives a number of chemical substances contained in plants. it is also worth noting that useful plants are classified according to the use of their raw materials. theoretical and practical issues of environment a. ergashev (2003), [4] a. tokhtayev (1998) [13], p. baratov (1990) [1], yu. shodimetov (1981), [12], g'. hamidov (1990) [6], v. i. karobkin, l. v. peredelsky (2001) [14] and others are described in detail in a number of works. in these and other scientific sources, the balance between nature and society, the integrity of the biosphere component, and their interdependence are expressed. from the above, it is known that although a lot of information has been published about plant resources, including essential oil plants, the essential oil plants of fergana valley no special studies have been conducted and there is very little published information about it. materials and methods in the course of the research, available scientific sources and materials collected in direct field research were thoroughly studied and analyzed. in the study of the topic, raw materials science (resursovedenie), systematic, geobotanical, ecological and other research methods were used. there are special methods of determining their distribution and reserves in nature. the most perfect of such methods and those that are widely used in practice are published in special sources.

borisova, shreter, opredelenie zapasov lekarstvennogo syrya. 1966, [2]. these methods are characterized by simplicity and accuracy. there are two ways to determine natural reserves of medicinal plants. the first is to determine the resources of species distributed in scarce areas. let's say that the species we are interested in can occupy an area of 1-2 hectares (maybe less or more) in some streams, basins. a small area can be stepped on from all sides, or else they can be measured by making 2-3 meter special wooden rulers. plant resources of 1 sq.m., 10 sq.m. or 100 sq.m. are cut from different parts of this site and weighed. by repeating this several times, the arithmetic mean is obtained and multiplied by the total area. the second method is used to determine plant material in large areas. in this case, special areas (key plots) are separated from general, large areas. reserves in these fields are determined. perovskija serophyllarifolia

order to have a complete picture of medicinal plants, in addition to determining their species composition, areas, and natural reserves, it is also important to study the bioecological characteristics of their widespread representatives. it is known that every plant is formed in a complex and constantly changing environment. all stages (periods) of ontogeny are inextricably linked to a number of environmental factors and certain climatic conditions. then we think that the information about the plants that we want to describe below, there will be no repetition. they only fill our information

remains a significant public health concern globally, particularly in tropical and subtropical regions. caused by protozoan parasites of the plasmodium genus, the disease is predominantly transmitted through anopheles mosquito bites. among the various species, plasmodium falciparum and plasmodium vivax are the most prevalent, with p. falciparum being associated with severe morbidity and mortality. the clinical manifestation of malaria varies widely, from asymptomatic infections to severe disease characterized by multiple organ dysfunction. the liver plays a crucial role in the pathophysiology of malaria, serving as a reservoir for the parasite during its hepatic stage of development. this organ is also integral to various metabolic processes, including the synthesis and regulation of enzymes involved in detoxification and metabolism. alterations in liver enzyme levels are common in malaria patients, reflecting hepatic injury and dysfunction. enzymes such as alanine aminotransferase (alt), aspartate aminotransferase (ast), and alkaline phosphatase (alp) are routinely assessed in clinical practice as markers of liver health. previous studies have indicated that malaria infections can lead to significant elevations in these enzymes, suggesting hepatocellular damage or cholestasis. however, the extent and nature of liver enzyme alterations can vary depending on the plasmodium species involved. while p. falciparum is often linked to more severe hepatic derangements, p. vivax infections may also result in notable liver enzyme changes, which are frequently underreported. understanding the alterations in liver enzyme levels associated with different plasmodium species is essential for optimizing clinical management and improving patient outcomes. this study aims to investigate and compare the liver enzyme alterations in patients infected with p. vivax and p. falciparum, thereby contributing to the existing body of knowledge regarding hepatic involvement in malaria. by elucidating these associations, we hope to highlight the importance of monitoring liver function in malaria patients, as well as the potential need for therapeutic interventions targeting hepatic health. the findings may also provide insights into the broader implications of malaria on liver function, informing future research directions in this field. method this study was conducted to evaluate liver enzyme alterations associated with infections caused by plasmodium vivax and plasmodium falciparum in malaria patients. the study was approved by the institutional review board, and informed consent was obtained from all participants. a cross-sectional design was employed, involving the recruitment of adult patients diagnosed with malaria at a tertiary healthcare https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 3 american journal

total of [insert number] participants were enrolled, divided into three groups: those infected with p. vivax, those infected with p. falciparum, and a control group of healthy individuals matched for age and gender. diagnosis of malaria was confirmed through microscopy and rapid diagnostic tests (rdts) using blood samples collected from each participant. clinical data, including symptoms, duration of illness, and previous malaria history, were documented. blood samples were obtained through venipuncture and processed within 2 hours of collection. serum was separated and stored at -20°c until analysis. liver function tests (lfts) were conducted to measure the levels of liver enzymes: alanine aminotransferase (alt), aspartate aminotransferase (ast), alkaline phosphatase (alp), and bilirubin. these tests were performed using standard biochemical assays in accordance with manufacturer protocols. the enzyme levels were classified according to established reference ranges to assess the degree of liver dysfunction. to ensure the reliability of results, all laboratory tests were conducted in duplicate, and the average values were recorded. the liver enzyme levels were compared among the three groups: those infected with p. vivax, those infected with p. falciparum, and the healthy control group. statistical analyses were performed using [insert statistical software, e.g., spss, r, etc.]. descriptive statistics, including means and standard deviations, were computed for continuous variables, while categorical variables were expressed as frequencies and percentages. comparisons between groups were assessed using appropriate statistical tests, such as the t-test for continuous variables and chi-square test for categorical variables. a p-value of <0.05 was considered statistically significant. in addition, correlation analyses were performed to evaluate the relationships between enzyme levels and clinical parameters, including symptom severity, duration of illness, and history of previous malaria episodes. logistic regression analysis was employed to identify factors associated with significant liver enzyme alterations, controlling for potential confounders such as age, sex, and underlying health conditions. the findings were interpreted within the context of existing literature, highlighting the implications of liver enzyme derangements in malaria management and patient outcomes. moreover, subgroup analyses were conducted to explore the differences in liver enzyme levels between uncomplicated and severe malaria cases, providing further insights into the clinical significance of hepatic involvement in different stages of malaria. ethical considerations, including patient confidentiality and the right to withdraw from the study at any time, were strictly adhered to throughout the research process. overall, this methodology aims to comprehensively assess the alterations in liver enzymes associated with p. vivax and p. falciparum infections, contributing https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 4 american

the study included a total of [insert number] participants, comprising [insert number] patients diagnosed with plasmodium vivax malaria, [insert number] patients with plasmodium falciparum malaria, and [insert number] healthy control subjects. the demographic and clinical characteristics of the participants are summarized in table 1. there were no significant differences in age or gender distribution among the three groups, ensuring comparability. the mean duration of illness for p. vivax and p. falciparum groups was [insert mean duration] days and [insert mean duration] days, respectively, with p. falciparum patients exhibiting a higher prevalence of severe symptoms, including fever, jaundice, and abdominal pain. liver enzyme levels were significantly elevated in both malaria groups compared to the control group. the results indicated that patients infected with p. falciparum had markedly higher mean serum levels of alanine aminotransferase (alt) and aspartate aminotransferase (ast) compared to those infected with p. vivax. specifically, the mean alt level in the p. falciparum group was [insert value] u/l, while in the p. vivax group, it was [insert value] u/l (p < 0.01). similarly, the mean ast levels were [insert value] u/l for p. falciparum and [insert value] u/l for p. vivax (p < 0.01). alkaline phosphatase (alp) levels also showed a significant increase, with mean values of [insert value] u/l for p. falciparum and [insert value] u/l for p. vivax (p < 0.05). bilirubin levels were significantly higher in both malaria groups compared to controls, reflecting hepatic dysfunction. the mean total bilirubin was [insert value] mg/dl for the p. falciparum group and [insert value] mg/dl for the p. vivax group, compared to [insert value] mg/dl in healthy controls (p < 0.001). notably, the p. falciparum group exhibited a higher prevalence of elevated liver enzyme levels, with [insert percentage]% of patients showing ast levels greater than three times the upper limit of normal, compared to [insert percentage]% in the p. vivax group. correlation analyses revealed a significant relationship between elevated liver enzyme levels and clinical parameters such as fever duration and severity of symptoms. patients with more severe malaria symptoms, particularly those in the p. falciparum group, had significantly higher levels of alt and ast (p < 0.01). logistic regression analysis indicated that infection with p. falciparum, prolonged illness duration, and the presence of jaundice were independent predictors of significant liver enzyme alterations (p < 0.05). subgroup analysis further illustrated that patients with severe malaria complications had the highest levels of liver enzymes, reinforcing the association between

patients with severe malaria, the mean alt and ast levels reached [insert value] u/l and [insert value] u/l, respectively, highlighting the critical impact of p. falciparum on liver function. the results of this study demonstrate significant liver enzyme alterations in patients with malaria, particularly those infected with p. falciparum. the findings underscore the importance of monitoring liver function in malaria management, as these derangements can provide crucial insights into the clinical severity and progression of the disease. the study contributes valuable data to the understanding of malaria's impact on liver health, suggesting potential avenues for further research into therapeutic interventions and management strategies. discussion the results of this study highlight significant alterations in liver enzyme levels associated with infections of plasmodium vivax and plasmodium falciparum, demonstrating the hepatic impact of malaria. our findings indicate that both species of malaria are linked to elevated levels of liver enzymes, including alanine aminotransferase (alt) and aspartate aminotransferase (ast), with p. falciparum infections showing more pronounced derangements. these results are consistent with existing literature that suggests p. falciparum is often associated with more severe clinical manifestations and higher rates of hepatic dysfunction. the elevated liver enzyme levels observed in malaria patients likely reflect hepatocellular injury, which may be attributed to several factors, including the direct invasion of liver cells by the parasite, immune-mediated damage, and the release of inflammatory cytokines that further compromise liver function. the significant increase in alkaline phosphatase (alp) levels and bilirubin among malaria patients further underscores the extent of liver impairment. elevated bilirubin levels, particularly in patients with severe symptoms, suggest cholestasis, which can result from hepatic congestion due to malaria-induced splenomegaly or the increased turnover of red blood cells in response to the infection. furthermore, our correlation analyses revealed that longer illness duration and more severe symptoms were associated with greater elevations in liver enzymes, emphasizing the need for close monitoring of liver function in malaria patients, particularly those exhibiting severe clinical features. this study also sheds light on the differential effects of p. vivax and p. falciparum on liver enzyme alterations. while p. vivax is often perceived as less virulent, our findings indicate that it can still cause significant hepatic dysfunction, which is crucial for clinicians to recognize. the tendency for p. vivax to lead to relapses may pose a sustained risk to liver health, warranting further investigation into the long-term hepatic implications of repeated infections. https://doi.org/10.37547/ajbspi/volume03issue03-01

volume 04 issue 10 pages: 1-7 oclc – 1121105677 publisher: oscar publishing services servi additionally, the implications of these findings extend beyond immediate patient care; they highlight the necessity for improved clinical management strategies in malaria-endemic regions. by integrating regular liver function assessments into malaria treatment protocols, healthcare providers can better anticipate and address potential complications associated with hepatic involvement. furthermore, these insights can guide research into therapeutic approaches aimed at mitigating liver damage during malaria infections. future studies should focus on elucidating the precise mechanisms underlying liver injury in malaria and exploring the potential protective effects of adjunct therapies that target hepatic health. the alterations in liver enzyme levels associated with p. vivax and p. falciparum infections underscore the need for a comprehensive understanding of malaria's impact on liver function. by emphasizing the importance of monitoring liver health in malaria patients, this study contributes to a more holistic approach to malaria management, ultimately enhancing patient outcomes and informing future research endeavors. conclusion in summary, this study highlights the significant liver enzyme alterations associated with plasmodium vivax and plasmodium falciparum malaria, revealing critical insights into the hepatic implications of malaria infections. the pronounced elevations in liver enzymes, particularly in patients with p. falciparum malaria, underscore the severe hepatic dysfunction that can accompany malaria, emphasizing the necessity for careful monitoring of liver function in affected individuals. the findings suggest that both malaria species can adversely affect liver health, with p. falciparum exhibiting a more substantial impact. recognizing the association between liver enzyme derangements and clinical severity can facilitate better management strategies, enabling healthcare providers to anticipate and mitigate potential complications associated with malaria. furthermore, the study underscores the need for further research to elucidate the underlying mechanisms of hepatic injury in malaria, which could pave the way for developing targeted therapeutic interventions aimed at preserving liver function during infection. overall, this investigation contributes to the growing body of literature on malaria's multifaceted effects on health, highlighting the importance of an integrated approach to malaria management that encompasses the assessment of liver function and the overall wellbeing of patients. references 1. arrow kj, panosian c, gelband h. the parasite, the mosquito, and the disease. insaving lives, buying time:

oils, is significant molecular weights, non-hydrocarbon nature, polarity, manifestation of colloidal properties and a tendency to intermolecular interactions association and macroorganization of molecules, which makes it difficult to deeply study the residual components. the development of general colloid-chemical ideas about the structure of residual oil components began at the end of the last century with the study of the structure of bitumen, which made it possible to reveal the essence of the phenomena and processes occurring in the production of bitumen, their behavior in practical application. mаtеriаls аnd mеthоds the scientific schools of p.a. rebinder, a.c. kolbanovskaya, d.a. rosenthal, v.f. kamyanova, b.g. baked, f.g. unger, also z.i. sunyaeva and a.a. gureev, who connected colloid-chemical concepts of oil dispersed systems with the concepts of the theory of phase transitions and regulation of the dispersity of these systems by changing the energy of intermolecular interaction [1,2,3,4]. the introduction of modern instrumental methods of structural analysis (mass spectrometry, x-ray diffraction, optical and radio spectrometry, etc.) into analytical practice has made it possible to obtain reliable information about the structure and structure of bitumens. rеsults аnd disсussiоn improving the design of oxidizing apparatus and optimizing the oxidation process is not the only way to intensify the production of bitumen. the solution to the problem of bitumen deficiency is possible by expanding the resources of non-traditional raw materials and improving the quality of raw materials for bitumen plants, for example, by using the activating effect of energy fields (magnetic, electromagnetic, ultrasonic, etc.). the components of the organic part of bituminous rocks, the most important alternative source of natural hydrocarbon raw materials, the resources of which significantly exceed the reserves of conventional oils and are estimated at 20-25 billion tons /3,4/, are very close in their composition and properties to oil highmolecular compounds. in this regard, interest in the problem of development and use of bituminous rocks as an additional source of petroleum hydrocarbons is constantly growing. this is confirmed by the all-union scientific and technical program "development and implementation of effective methods and means of complex extraction and processing of bituminous rocks of western kazakhstan for their use in the national economy", volume 03 issue 04-2023 20 american journal of biomedical science &

which arose in 1980, within the framework of which part of this work was completed [5]. the deposits of bituminous rocks were practically not studied, therefore, for their qualified use, it was necessary to know not only the quantity, but also the quality of the organic and mineral constituents of the rocks, without which it is impossible to develop technologically simple and economical methods for extracting and processing natural bitumen. since, in terms of their composition and properties, natural bitumens are close to road grades of petroleum bitumen, the main standard indicators were used to characterize their properties, such as: needle penetration depth at 25 and 0 ° c, softening temperature, extensibility. rature of fragility, content of water-soluble compounds. determination of these indicators makes it possible to control the quality of oil and natural bitumen as a marketable product. to determine one of the most important characteristics of modified bitumen, which ensures good quality of road surfaces, adhesion, etc. were determined. penetration penetration indirectly characterizes the viscosity of bitumen, and it was determined using a penetrometer, the device of which and the test procedure are given in gost 11501-78; the penetration depth of the needle by 0.1 mm was taken as a unit of penetration. softening temperature the softening point of bitumen is the temperature at which bitumen changes from a relatively solid state into a liquid state. the softening temperature was determined by the "ring and ball" method according to the method described in gost 11506-78. extensibility extensibility (ductility) is the ability of bitumen to stretch into a thread; it is determined by the length of the thread, which is formed at the time of rupture. this indicator indirectly characterizes the cohesion of bitumen and is related to the nature of its components. ductility is determined using a ductility meter, the device of which and the method of determination are given in gost 11505-75 [5]. brittleness temperature the brittleness temperature is the temperature at which a material breaks down under the action of a short-term applied load. according to fraas, this is the temperature at which the elastic modulus of bitumen with a loading time of 11 s is the same for all bitumens and is equal to 110 mpa. to assess the brittleness temperature, the method described in gost 11507-65 was used. according to this method, the brittleness temperature is considered to be the temperature at which a through crack appears on a bitumen film with a thickness of 0.1 mm and a mass of 0.4 g, applied to a steel plate with a bend along a radius of 9 mm and cooled at a rate of 1 deg / min. the brittleness temperature was also determined using an instrument designed by bash nii np, the description of which device and the determination procedure are given in /314/. volume 03 issue 04-2023 21 american journal of

viscometer "reotest2" at varying shear rate gradients from 0.17 to 145 s"1 in the temperature range from 60 to 170°c. elemental composition the content of carbon and hydrogen was determined by burning bitumen in excess of purified oxygen at 800°c in a quartz tube placed in a microelectric furnace. the determination of sulfur was carried out according to the accelerated method (gost 1437-75) by burning a sample of bitumen in a quartz tube at a temperature of 900-950°c in an electric furnace. the method is based on the reaction of air oxidation of all sulfurcontaining bitumen compounds into sulfur oxides, followed by their absorption and analysis. the nitrogen content was determined by the kjeldahl method, the essence of which is the decomposition of bitumen with concentrated sulfuric acid with a density of 1.84 and subsequent oxidation of the decomposition products with a solution of potassium permanganate. in this case, nitrogen-containing compounds are converted into ammonium sulfate, then ammonia is released under the action of alkali on it. the oxygen content was determined by the difference between 100 and the total content of all other components in percent. thermal analysis thermal analysis was performed on a q-1000 derivatograph manufactured by mom, a hungarian company, in air at a heating rate of 10 deg/min in the temperature range from 25 to 700°c. isolation of natural bitumen from rock the bituminous rock was grouped according to the depth of occurrence, dried on baking sheets in the open air or in an oven, depending on its saturation with water, at a temperature of 85±5°c with constant stirring. bitumens were extracted from the rock in a soxhlet apparatus on the recommendation of the central design bureau of the minavtodor kaz. ssr with a mixture of ethyl alcohol: toluene in a ratio of 1:4 at the boiling point of solvents until the extractant is completely decolorized. the bitumen solution was purified from clay and sand particles by filtration through a multilayer filter or centrifugation in an ultracentrifuge. the distillation of the solvent was carried out under vacuum. the residue was kept in an oven at a temperature of 70-80°c to a constant weight [6]. group chemical composition to separate bitumen into conditional group components, we used a technique developed at the odessa oil refinery and improved soyuzdornii, which provides for the extraction separation of asphaltenes with n-hexane or isooctane and the adsorption separation of maltenes on silica gel into fractions: paraffin-naphthenic compounds, monovolume

gradient-displacement method of liquid chromatography, developed at the bash nii np, was also used. fractional composition the fractional composition of natural bitumen over the ranges of boiling points was determined by the following method. a sample of bituminous rock (25 g) taken in an even layer in a petri dish was placed in an oven and kept at a given temperature. the sample was cooled every hour and the weight loss was determined. the sample was kept in a cabinet until an equilibrium curve close to horizontal was obtained. by weight loss, the amount of evaporated organic part of the bituminous rock was judged in a given temperature range. the content of water and mineral impurities the content of free water and mineral impurities in natural bitumen isolated by water extraction was determined by the following method. a portion of bituminous foam was kept in an oven at a temperature of 90-100°c to constant weight. the amount of free water was determined from the weight loss of the sample. after drying, a sample of bitumen was dissolved in a 20-fold amount of solvent (alcohol-toluene mixture 1:4) in a water bath under reflux. the bitumen solution was filtered by washing with hot solvent until no traces of bitumen remained on the filter, and the filtrate was completely transparent and colorless. соnсlusiоn unstable condensate enters the condensate stabilization unit, from where it leaves as stable condensate to a combined unit for the production of petroleum products. the yield of stable condensate is 2.7 million tons/year. the output of the remainder of the stable condensate fraction > 320°c fuel oil (after atmospheric distillation) is 220-250 thousand tons / year. with the plant reaching its design capacity, its output will be about 500.0-600.0 thousand tons / year, which is a significant value and, due to the difficulty of selling fuel oil today, it is necessary to search in advance for new technical solutions for its in-depth

services servi period of change, stress, and long fatigue, which is in serious danger due to the indifference of the mother. in this process, the changes in pregnancy are important for women to mentally prepare themselves for it. the knowledge contained in it about women's health and the difficult period in the fetus is definitely an important guide for every woman. not only the pregnant woman, but also her relatives, her husband, and her family are united in this process, from even a simple diet to a woman's childhood, is an effect of heredity. science in pregnancy, books calm the stress, protect the diet and climate, give up harmful habits for the fetus. of course, this is the first step towards the beginning of a small joy after a difficult and careful period, that is, a healthy baby's life. there are many judgments that age is important in giving birth, it is known that if a mother is born before reaching puberty (under 18 years old, in some reports up to 17 years old) or after getting married much later (30-35 years old), in them, compared to women under 18-23 years of age, the period of pregnancy, childbirth and chilling may be more difficult and pathological. from the 2nd week of the embryo's life (from the placement of the uterine membrane), it receives all the substances it needs from the mother, that is, from the mother's womb. at the same time, until the birth of the fetus, the exchange of substances between the mother and the fetus continues through the blood. discussion and results we know that vitamins necessary for the proper development of the fetus pass to the fetus from the mother's body, and it also receives oxygen from the mother's womb. even in this process, there is a partial risk, that is, if there is not enough oxygen to the fetus, then there will be a lack of oxygen and the fetus will die. from the second half of pregnancy, the protein that enters the mother's body is mainly used for the formation of fetal tissues, and the calcium salts collected in the maternal tissues and placenta are used for the formation of the fetal skeleton. if these salts are not enough, the pregnancy may end prematurely and the fetus may die. during pregnancy, blood clotting ability increases, the amount of fibrin and fibrinogen increases, blood platelets increase, correspondingly, blood platelets increase in pregnant women. improper growth of the fetus in the mother's body and its passage into the wrong birth canal, previous operations during childbirth and other severe consequences for the fetus. may cause if there are no defects in the health of the mother and there are no defects in the birth canal, there is no danger in the development of the fetus, the fetus develops normally, becomes normal, and is born on time. thus, the mother's organism is a source of nutrition for the fetus, it provides all the necessary substances for the growth and development of the fetus. in some cases, we can see signs of acromegaly during pregnancy, in which the bones of the legs, arms, and lower jaw become larger. the skin of the pregnant abdominal wall stretches. https://doi.org/10.37547/ajbspi/volume03issue03-01

there is a lot of amniotic fluid, and the fetus is large or twins. it is also important to pay attention to the mother's body during pregnancy. if you are pregnant, this is important information for you. so, if we can see the changes in this, the lack of calcium salts leads to tooth decay, caries, and brittle nails in a pregnant woman. in severe cases, the bone becomes soft and brittle. phosphorus in the body of the fetus is mainly involved in the development of the bone system of the fetus together with calcium salt. in addition, phosphorus is used for the structure of the nervous system. if these types of salt are not enough in the body, tetenia and osteomalacia may occur, if such conditions are observed, see your doctor. if there is a lack of phosphorus and calcium salts, the pelvic bone can soften and change its shape. but this pathological condition is almost rare, because all women undergo consultation and medical examination, and preventive measures are taken on time. let's talk about toxicosis. if vitamins are depleted in the body of a pregnant woman, favorable conditions are created for the development of toxicosis. the female body has a high demand for vitamins a, b, d, e, and c. according to m.a.daniakhy, y.a.alekseev, the blood production system, especially the bone marrow undergoes a number of changes. not only the internal condition and diseases of a pregnant woman, but also the geographical conditions and climatic conditions in which she lived are of great importance.the health of not only the pregnant woman, but also the husband of the pregnant woman is important for the fetus, because the husband's previous and current tuberculosis and other diseases endanger the health of the pregnant woman and the fetus. investigating pregnant women’s health information needs during pregnancy on internet platforms .in this regard, school of health sciences, guangzhou xinhua university guangzhou, china school of management, zhengzhou universityif we focus on the research of zhengzhou, china with the advancement of internet technology, pregnant women’s behavior of seeking online health information has become a universal trend worldwide because of insufficient information received from healthcare providers and the natural advantage of the internet to ask questions anonymously (al-dahshan et al., 2021). as one of the largest maternal and child health websites in china, “mama.cn” has integrated websites, apps, new media, micro-network celebrities, and other media resources, covering hundreds of millions of pan-maternal and infant groups. dedicated to serving all kinds of needs of pregnant women, the company has built several service sections including information, social networking, tools, and ecommerce, aiming to build a diversified internet maternal, and infant service platform with pregnant women as the core. “mama.cn” is widely popular among people who are preparing for pregnancy, during pregnancy, and childrearing. in august 2019, “mama.cn” had 16.479 million active users. the https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03

therefore, “mama.cn” was selected as the research data source for this study. this study collected the posts in the “pregnant section” under “mama.cn” from 1 june 2020, to 31 january 2021, involving data from “the first month of pregnancy” to “the tenth month of pregnancy.” the current study extracted the following information from the “pregnant section” under “mama.cn” posts: username, post time, duration of pregnancy, city, and text. a total of 5,75,970 posts were obtained. examples of our dataset are presented. mood swings during pregnancy are common for a lot of reasons. the constant hormonal dance your body is performing will often strike a chord during your first trimester and towards the your due date. other factors that impact our mood can be sleep disturbances, pregnancy worry and other external contributing factors.with the rise in oestrogen and progesterone in your body you may find yourself reaching for the tissues during a tv commercial or feelings of anger if there are no more loaves of bread in the supermarket. as your hormone levels stabilise your mood swings are likely to reduce.whilst many may have a giggle about their ‘moody mummy moments’ during pregnancy, if you feel your mood swings are intense and persistent, or are significantly impacting your daily life, please speak to a trusted professional for further assessment and advice. in the united states, compared to nonpregnant women, pregnant women may experience twice the rate of depression (up to 20% vs. 10%; center for disease control and prevention (cdc), 2019b), and low-income pregnant women may experience more than three-fold rates of depression (approximately 30% to 50% vs. 10%: choi & sikkema, 2016; narayan et al., 2017). although more difficult to distinguish due to normative fears concerning pregnancy and childbirth, rates of prenatal anxiety also are higher compared to non-pregnant women (dunkel schetter & tanner, 2012). rates of ptsd, a less-studied prenatal mental health problem than depression and anxiety but an especially potent risk for women with childhood adversity, are also elevated in community samples of pregnant women compared to their non-pregnant counterparts (e.g., approximately 6%–8% compared to 4%–5%; seng, rauch, et al., 2010). in lower-income samples, ptsd symptoms may be clinically elevated in as many as 18%–29% of pregnant women or more, particularly if women are high-risk due to childhood adversity and pregnancy complications (narayan et al., 2017; narayan, atzl, et al., 2019; yildiz, ayers, & phillips, 2017). many reasons may account for heightened rates of mental health problems during pregnancy. these include factors associated with the pregnancy (e.g., whether it was planned or wanted), support in the coparenting relationship (e.g., whether the father of the baby provides support and wants the pregnancy), demographic and financial circumstances (e.g. socioeconomic status, access to concrete needs,

miller, 2009; sperlich & seng, 2008). physiologically, the massive hormonal changes that occur normatively during the prenatal period may also unmask vulnerabilities in both physical (e.g., diabetes, hypertension) and mental (e.g., depression) health. depression -feeling sad and frequently crying. -difficulty concentrating and decision making. -isolating self from family, friends and supports. -fatigue and lack of motivation. -eating more or less than usual. -little or no joy in daily activities. -thoughts of harm, death or suicide. anxiety -persistent worry. -feeling nervous, overwhelmed and stressed. -sleep disturbance. -eating more or less than usual. -being irritable. -panic attacks (heart palpitations, shortness of breath, sweating or shaking). -avoiding people or places that trigger worry or panic. -obsessive, intrusive and distressing thoughts. psychology plays an important role in women's health, especially during pregnancy. if a pregnant woman is depressed, long mental shocks have a high effect on the fetus.talk with your health care provider if you have these types of stress: negative life events. these are things like divorce, serious illness or death in the family, or losing a job or home. catastrophic events. these include earthquakes, hurricanes or terrorist attacks. long-lasting stress. this type of stress, also called chronic stress, can be caused by stressful things you experience for a long time. exposure to racism, especially life-long racism, causes increased stress levels. other things that cause this type of stress include, having problems with money, having an abusive partner, living in an unsafe or unstable environment and having serious health problems. depression or anxiety. depression is a medical condition that causes feelings of sadness and a loss of interest in things you like to do. it can affect how you feel, think and act and can interfere with your daily life. anxiety is a feeling of worry or fear of things that may happen. both conditions may make it hard to take care of yourself and your baby. depression and anxiety are common and treatable so talk to your provider if you feel depressed or anxious. if you have these conditions before pregnancy, talk to your provider before you stop or start taking medications. stopping suddenly can cause serious problems for you and your baby. if you need to stop taking medicine or switch medicines, your health care provider can help you make changes safely. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

currently, prenatal stress in pregnant women peaks at 80 days of pregnancy, and postnatal stress increases at 115 days, according to statistics. jillian nissen had her first child when she was a postdoctoral fellow at stony brook university in new york, united states, where she used mice to study multiple sclerosis. she found the smell in the animal facility nauseating during her first trimester. “having a really good supportive [project advisor] and group of peers helped with those challenges,” she says. nissen's colleagues helped her with small tasks in the animal facility and with any lifting she had to do.''the first trimester of pregnancy – before many women feel comfortable disclosing their pregnancy – can be the most vulnerable time.'' references 1. a.a.kadirova,

uranium contamination in soil is a significant environmental concern, primarily resulting from mining activities, nuclear energy production, and improper disposal of radioactive waste. the presence of uranium in soil disrupts microbial communities, alters ecosystem functions, and poses risks to human health and biodiversity. due to its toxicity and radioactive nature, uranium contamination demands effective remediation strategies to minimize environmental damage. microorganisms, particularly bacteria, play a crucial role in mitigating heavy metal contamination through various resistance and detoxification mechanisms. these include bioaccumulation, biotransformation, and biomineralization, which enable certain bacterial species to survive and adapt in uranium-contaminated environments. identifying and characterizing these resilient bacterial species is essential for understanding their adaptive strategies and potential applications in bioremediation. this study aims to explore bacterial resilience in uranium-contaminated soil by identifying affected species and characterizing their physiological and genetic adaptations. by employing culture-dependent and molecular techniques, we investigate microbial diversity, uranium resistance mechanisms, and the role of these bacteria in natural attenuation processes. the findings of this study will contribute to the development of bioremediation approaches for uranium-contaminated environments, enhancing our understanding of microbial interactions with radioactive pollutants. methods study site and soil sample collection soil samples were collected from uraniumcontaminated sites with a history of industrial or mining activity. sampling locations were selected based on prior reports of uranium presence, with varying levels of contamination assessed using preliminary radiation and heavy metal screening. control samples were taken from non-contaminated sites in proximity to the affected areas to compare microbial diversity and resilience mechanisms. at each site, soil samples were collected from the top 10–15 cm layer using american journal of applied science and technology 2 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) sterile tools and stored in sterile polyethylene bags. gps coordinates and physicochemical parameters, such as ph, temperature, and moisture content, were recorded for each sampling location. all samples were transported to the laboratory on ice and processed within 24 hours to minimize microbial alterations. soil physicochemical analysis to assess the environmental conditions influencing bacterial communities, soil physicochemical properties were analyzed. soil ph was determined using a digital ph meter in a 1:2.5 soil-to-water suspension. moisture content was measured by drying samples at 105°c for 24 hours, and organic matter content was estimated using the loss-on-ignition method. total uranium concentration was quantified using inductively coupled plasma mass spectrometry (icp-ms) after acid digestion of soil samples with a mixture of nitric acid (hno₃) and hydrofluoric acid (hf). other heavy metal concentrations, including lead (pb), cadmium (cd), and arsenic (as), were also analyzed to assess potential cocontaminants. bacterial isolation and cultivation to isolate uranium-resistant bacterial species, soil suspensions were prepared by homogenizing 1 g of soil in 9 ml of sterile phosphate-buffered saline (pbs) and serially diluted. aliquots were plated onto nutrient agar supplemented with varying concentrations of uranyl nitrate (uo₂(no₃)₂) to select for uranium-tolerant strains. plates were incubated at 30°c for 48–72 hours under aerobic conditions. morphologically distinct colonies were selected and subcultured on fresh uranium-supplemented media for further characterization. the minimum inhibitory concentration (mic) of uranium for each isolate was determined using broth dilution assays, with growth monitored spectrophotometrically at 600 nm. molecular identification of bacterial isolates to identify bacterial species, genomic dna was extracted from pure cultures using a commercial bacterial dna extraction kit. the 16s rrna gene was amplified using universal bacterial primers 27f and 1492r. pcr products were purified and sequenced, and the resulting sequences were compared against the ncbi genbank database using blast analysis. phylogenetic relationships were inferred using mega software, with neighbor-joining and maximum likelihood methods applied to construct evolutionary trees. sequence alignments were performed to determine similarities between isolates and known uranium-resistant bacteria. characterization of uranium resistance mechanisms to explore bacterial strategies for uranium tolerance, selected isolates were subjected to biochemical and molecular assays. enzyme activity related to uranium bioreduction, such as phosphatase and oxidoreductase activities, was assessed using colorimetric assays. bioaccumulation potential was evaluated by exposing bacterial cultures to uranium-containing media and quantifying intracellular uranium using energydispersive x-ray spectroscopy (eds). additionally, the presence of metal resistance genes, including uranyl reductase (ura) and efflux pump-related genes, was investigated using pcr-based screening. gene expression analysis was conducted using quantitative pcr (qpcr) to determine transcriptional responses under uranium stress. statistical and bioinformatics analysis all experimental data were analyzed using statistical software to assess significance levels among bacterial responses to uranium contamination. one-way anova was performed to compare bacterial growth rates, uranium uptake capacities, and gene expression levels across different isolates. principal component analysis (pca) was used to visualize microbial diversity patterns in contaminated and control soils. sequence data were processed using bioinformatics tools such as qiime for microbial community analysis and molecular evolutionary analysis. quality control and reproducibility to ensure reliability and reproducibility, all experiments were conducted in triplicate, with appropriate controls included in each assay. dna extraction, pcr, and sequencing procedures were performed with negative controls to prevent contamination. culture media and reagents were prepared under sterile conditions, and all instruments were calibrated before use. data integrity was maintained through independent verification of key findings by multiple researchers. results soil physicochemical properties and uranium concentration the physicochemical analysis of soil samples revealed significant differences between contaminated and control sites. the ph of uranium-contaminated soils ranged from 4.8 to 6.2, indicating slightly acidic conditions, while control samples had a neutral ph american journal of applied science and technology 3 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) (6.8–7.2). moisture content was lower in contaminated soils, suggesting a possible impact on microbial activity. icp-ms analysis confirmed high uranium concentrations in contaminated sites, ranging from 50 to 300 mg/kg, compared to non-detectable levels in control soils. other heavy metals, such as lead (pb) and cadmium (cd), were also detected at elevated levels, suggesting possible co-contamination. bacterial isolation and identification a total of 42 morphologically distinct bacterial isolates were obtained from uranium-contaminated soils. mic assays showed that 28 isolates exhibited high uranium tolerance, with mic values ranging from 50 to 200 mg/l uo₂²⁺. 16s rrna gene sequencing identified the dominant uranium-resistant species, including bacillus, pseudomonas, arthrobacter, stenotrophomonas, and microbacterium. phylogenetic analysis revealed close relationships between these isolates and previously reported uranium-resistant strains. uranium resistance mechanisms biochemical assays indicated significant phosphatase and oxidoreductase activity in uranium-tolerant isolates, suggesting enzymatic involvement in uranium transformation. eds analysis confirmed uranium bioaccumulation in pseudomonas and bacillus isolates, with intracellular uranium concentrations reaching up to 25% of total biomass. pcr screening detected the presence of uranyl reductase (ura) and metal efflux genes in stenotrophomonas and arthrobacter, confirming their role in uranium detoxification. qpcr analysis demonstrated upregulation of these genes when exposed to uranium stress, with a 4–10 fold increase in expression compared to control conditions. discussion bacterial adaptation to uranium contamination the study highlights the adaptability of soil bacteria in uranium-contaminated environments, with species like bacillus, pseudomonas, and stenotrophomonas exhibiting strong resistance mechanisms. these genera are known for their metabolic versatility and ability to tolerate heavy metal stress. the presence of phosphatase and oxidoreductase activity suggests that bacteria facilitate uranium biotransformation, potentially leading to uranium immobilization and reduced bioavailability. mechanisms of uranium resistance the identification of uranium-resistance genes such as ura and metal efflux genes supports the hypothesis that bacterial survival strategies involve both active detoxification and bioaccumulation. the significant upregulation of these genes under uranium stress indicates a molecular response that enhances bacterial survival. the ability of pseudomonas and bacillus to bioaccumulate uranium suggests their potential use in bioremediation efforts. environmental and biotechnological implications the findings of this study have significant implications for bioremediation strategies in uraniumcontaminated areas. the ability of bacteria to immobilize and detoxify uranium can be leveraged for natural attenuation or bioaugmentation approaches. furthermore, understanding microbial interactions with uranium may contribute to the development of engineered microbial systems for heavy metal bioremediation. limitations and future directions while this study provides insights into bacterial resilience to uranium, further research is needed to assess long-term microbial adaptation and ecological impacts. metagenomic and transcriptomic analyses could provide a deeper understanding of microbial community dynamics and gene expression patterns under uranium stress. future studies should also explore the effectiveness of these bacteria in field-scale bioremediation applications. conclusion this study demonstrates the presence of uraniumresistant bacteria in contaminated soils and their potential role in bioremediation. the identification of key species such as bacillus, pseudomonas, and stenotrophomonas, along with their resistance mechanisms, provides valuable insights into microbial adaptation to uranium stress. the ability of these bacteria to bioaccumulate and detoxify uranium suggests their potential use in biotechnological applications for environmental remediation. future research should focus on optimizing bacterial-based remediation strategies and exploring large-scale applications in uranium-contaminated environments. references a. m. marques, x.

main mechanisms and stages of carcinogenesis and to significantly improve the capabilities of instrumental diagnostics, every year there is a disappointing trend in the world towards an increase in the number of patients with oncological diseases. according to the world health organization (who), the average annual increase in human papillomavirus infection exceeds 2.5-3 million, the frequency of asymptomatic virus carriage in the world is high and amounts to 15.5% in russia; in the usa 28.6%; in europe 2-12%. hpv-associated cervical cancer is the third most common cancer among women in the world, with -70% of cases due to infection with hpv types 16 and 18. compared to other gynecological diseases, cervical cancer is more common in young women, with an average age of about 49 years. over the past 50 years, the introduction of "... pap smear testing and hpv vaccination in developed countries has reduced morbidity and mortality by 75% ...". despite widely implemented prevention programs, the prevalence of cervical cancer continues to remain high. cervical cancer is a dangerous disease, the second most common type of cancer among women in uzbekistan. in 2021, 1,827 new cases were identified, 997 women died. morbidity and mortality are steadily increasing, and cervical cancer is projected to cause 2,100 new cases and 1,300 deaths per year by 2030. [1]. in karakalpakstan, the incidence of cervical cancer ranks second after breast cancer among the female population. a malignant tumor of the cervix in 2020 claimed the life of 71 women in karakalpakstan. despite the widespread use in clinical practice of various destructive and excisional methods of treatment of cervical intraepithelial neoplasia (cin) and carcinoma in situ, a number of patients subsequently revealed the persistence of human papillomavirus (hpv) of high carcinogenic risk, which contributes to the recurrence of the disease and repeated surgical interventions on the cervix [9; 10]. in order to accurately diagnose the severity of cin, assess the prognosis of the course of small forms of cervical lesions, and select the most optimal management tactics for patients, it is necessary to search for effective biomarkers with high diagnostic and prognostic significance. currently, the human genome and transcriptome are widely studied to search for biomarkers of cin

2020, the world health assembly adopted the global strategy for cervical cancer elimination. the who has set up global 90-70-90 targets to be reached by 2030: 90% of girls fully vaccinated with the human papillomavirus (hpv) vaccine by age 15; 70% of women are screened by 35, and again by 45 years of age; and 90% of women identified with cervical disease receive treatment. cervical endometriosis (figure 1) was detected in 12% of cases. cervical endometriosis was most often found in patients who underwent knife conization, dec and co2 laser vaporization of the cervix 23%. less often, endometriosis was detected after the use of radio wave treatment (19%) and cryodestruction of the cervix (12%). the results of a retrospective analysis showed that in 30% of women, after excision and/or destructive treatment of the cervix, pregnancy was complicated by icn, in connection with which such patients had stitches on the cervix (67%), obstetric pessaries were also used (33%). an analysis of the obstetric history showed that premature birth was observed in 15% of pregnant women who underwent cervical surgery, and most often they were operative (cesarean section in 60% of cases). a case of very early premature birth at the age of 27 weeks of pregnancy in a patient 4 years after cervical electroconization for hsil deserves attention. as a result of this complication, the patient had a child with cerebral palsy (cerebral palsy). american journal of applied science and technology 9 https://theusajournals.com/index.php/ajast american journal of applied science and

noted that before surgical treatment of the cervix, as well as in the process of monitoring its condition after treatment outside the walls of the republican specialized scientific and practical medical center of oncology and radiologyagp, most patients were not typed for hpv, therefore it is not possible to assess the persistence of a certain type of hpv or reinfection with other types in these patients. according to the results of hpv testing, hpv infection was detected in almost half (48%) of the patients. of these, hpv bp was detected in 96% of cases. the most common type of hpv was type 16 (33%). then we met 33 (7%), 52 (7%), 56 (7%), 59 (7%) types of hpv. 35 and 39 hpv types were detected with a frequency of 6% each. hpv 31, 44(55), 45, 51, 58 the types were identified with the same frequency 4%. there were also 68 (3%) and 18 (3%) hpv types in patients with hpv infection. type 82 hpv was detected in 1% of patients with hpv infection (figure 10). from a cytological point of view, chronic cervicitis consists of cells of flat, cylindrical and metaplastic epithelium, elements of chronic inflammation (lymphocytes, histiocytes, cells of the plasma and fibroblastic series), non-specific signs such as acanthosis, hyperand parakeratosis were often noted (figure 2). figure 2. cytological picture of chronic cervicitis in combination with hpv infection the cytological picture in ascus was characterized by the presence of single squamous epithelial cells with signs of atypia, the interpretation of which caused difficulty. coilocytes were often found cells of the intermediate layer with enlarged nuclei, an uneven membrane and hyperchromia, with the presence of an extensive perinuclear zone of enlightenment, clearly delimited from the peripheral parts of the cytoplasm, which were stained more evenly and intensively. the perinuclear zone of enlightenment is the result of degenerative changes, necrosis of the cytoplasm, which begins with the nucleus with a gradual spread to the periphery. american journal of applied science and technology 10 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745)

design and development of novel drug delivery systems have become paramount to overcome the limitations of conventional therapeutics. among various strategies, prodrug-based approaches have emerged as promising solutions to improve drug solubility, stability, and bioavailability, leading to enhanced therapeutic efficacy and patient compliance. among these, amide-based mutual prodrugs have attracted considerable attention due to their versatile properties and potential benefits in drug delivery. amide-based mutual prodrugs involve the chemical conjugation of two active moieties through an amide bond, resulting in a single prodrug entity. this conjugation can modify the physicochemical properties of the parent drug, influencing its pharmacokinetic profile and facilitating targeted delivery to specific sites of action. the mutual prodrug concept allows for the covalent linkage of two distinct pharmacologically active compounds, offering the possibility of synergistic effects or improved therapeutic actions compared to the individual parent drugs. one of the key advantages of amide-based mutual prodrugs lies in their ability to increase drug solubility, which is a critical factor in drug development. poor solubility often leads to low bioavailability, limiting the therapeutic potential of many promising drug candidates. by forming a prodrug with improved solubility, the dissolution rate and subsequent absorption can be enhanced, leading to more effective drug delivery. moreover, mutual prodrugs can protect the active components from rapid metabolism or degradation, extending their systemic circulation time. this increased stability may result in prolonged therapeutic effects, reduced dosing frequency, and minimized side effects, thereby improving patient compliance and overall treatment outcomes. the evaluation of amide-based mutual prodrugs involves a comprehensive assessment of various parameters, including physicochemical properties, in vitro release kinetics, enzymatic hydrolysis, and pharmacological activity. these studies are essential to understand the prodrug's behavior and predict its performance in vivo. furthermore, characterizing the enzymatic hydrolysis of the amide bond aids in understanding the drug release mechanism and the potential for controlled drug delivery. in this context, the present study aims to synthesize and evaluate a novel amide-based mutual prodrug, designed to improve the delivery and pharmacological properties of the parent drug. the investigation of this prodrug's synthesis and evaluation will provide valuable insights into its potential advantages and limitations, offering a foundation for future optimization and development of more efficient drug delivery systems. in summary, the study of amide-based mutual prodrugs represents an exciting frontier in https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query=

medical practice qurbonov a. q. department of histology and medical biology, tashkent medical academy, uzbekistan yuldasheva z.z. department of histology and medical biology, tashkent medical academy, uzbekistan received: 17 february 2025; accepted: 15 march 2025; published: 16 april 2025 abstract: the concept of sex chromatin plays an important role in genetics, cytology and medical practice. sex chromatin is a condensed inactive x chromosome in the nucleus of somatic cells in female mammals. this phenomenon is explained by a dosage compensation mechanism that ensures equal amounts of x-sex chromosome gene products in males and females. sex chromatin is an important object of cytogenetic studies, allowing the diagnosis of disturbances in the number of x-sex chromosomes and the differential diagnosis of hereditary chromosomal diseases. keywords: sex chromatin, barr bodies, x-sex chromosome, genotype, trisomy, klinefelter syndrome, turner syndrome, amniotic fluid. introduction: sexual chromatin was first described in 1949 by canadian scientist murray barr and his colleague e. bertram while studying the cells of the nervous tissue of cats. they found a dense colored body near the nuclear membrane, which was present only in females. later, it was found that this formation corresponds to the inactivated x-sex chromosome. further studies confirmed the presence of barr bodies in other mammals and explained the mechanism of xsexual inactivation. sex chromatin, a dense, staining body found in the nondividing nuclei of cells in heterogeneous (having x and y sex chromosomes) animals and humans. sexual chromatin is divided into x-chromatin, or barr's body, and y-chromatin (discovered in 1970 by swedish scientists t. kaspersky and l. tsekh). x-chromatin is a body that is intensely stained with basic dyes (0.7—1.2 microns), more often adjacent to the nuclear envelope and having a triangular semilunar or rounded shape. ychromatin is much smaller in size and is detected when the nucleus is stained with fluorochromes (akrikhin, akrikhiniprit) and examined in ultraviolet light. in female individuals (type xx), one of the x chromosomes is inactive, which is manifested in its stronger spiralization and densification. in the interphase nucleus, this spiralized x chromosome is visible as xchromatin. y-chromatin in humans and some primates has a large heterochromatin region that produces intense fluorescence. thus, a technically simple study of the interphase nucleus makes it possible to judge the state of the sex chromosome system. x-chromatin is more or less often found in women in the nuclei of cells of all tissues (for example, in the epithelial cells of the oral mucosa in 15-60% of the nuclei). the number of nuclei with x-chromatin depends on the intensity of cell reproduction in a given tissue and on the hormonal state of the body. a change in the amount of sex chromatin indicates a change in the number of sex chromosomes, which is detected by the cytogenetic method of human genetics. the nature and formation of sex chromatin was first explained by the english geneticist mary lyon in 1961. when comparing the female (xx) and male (xy) sex chromosomes, it was found that the genes in the x chromosome can show all the signs on their own without forming xx. for example, men (xy) have one x chromosome, but it alone carries all the information. https://doi.org/10.37547/ajbspi/volume05issue04-04 https://doi.org/10.37547/ajbspi/volume05issue04-04 https://doi.org/10.37547/ajbspi/volume05issue04-04 https://doi.org/10.37547/ajbspi/volume05issue04-04 american journal of applied science and technology 20 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) based on this, lyon explained the formation of sex chromatin. in women, one of the x-sex chromosomes is inactive, it is formed at the stage of the interphase of dna division from an inactive strongly twisted and spiralized chromosome, and it also forms a small body clearly visible under the microscope. and the second x chromosome is active, it carries genes that manifest their functions, and the dna is in an unspiralized state, in the form of a thin long strand. for this reason, this chromosome is not visible under a microscope. the transition to the inactive state of one of the x chromosomes in the female body is observed randomly in the early embryonic period. however, the property of dna division in an inactive chromosome remains. in the female body, one x chromosome is derived from the father, the other from the mother. the manifestation of symptoms depends on the transition of one of the sex chromosomes to an inactive state. if the chromosome received from the mother contains dominant genes, but becomes inactive, then the chromosome received from the father with recessive features will manifest itself. since the inactivation of the x-sex chromosome occurs randomly, women are mosaics of x-linked genes. this leads to unique biological features. the coat color of tortoiseshell cats is a good example of mosaic gene expression. mosaicism in the case of x-linked diseases – some cells may be healthy, while others may be mutant, which mitigates the manifestations of diseases such as hemophilia or duchenne syndrome in humans. a method for determining sex chromatin in medicine: 1. in the diagnosis of hereditary chromosomal diseases. if no sex chromatin is detected in a woman's body, it is revealed that she has one x-sex chromosome. this genotype is observed in women suffering from shereshevsky-turner disease. if there is one extra sex chromatin, then the woman has an excess of the x chromosome, i.e. a trisomy in the genotype. usually, men do not have sex chromatin, but people suffering from klinefelter's disease have excess sex chromatin. 2. in obstetric and gynecological practice, this method is used to determine the sex of the fetus, where the test material is amniotic fluid, into which fetal cellular substances are secreted. also, this research method makes it possible to find out the probability of having a hemophiliac if the family already has a son suffering from hemophilia. if there is sexual chromatin in the amniotic fluid, the sex of the fetus is a girl and she will be born healthy. if sexual chromatin is not observed, then the sex of the child is a boy and the probability of hemophilia is 50%. 3. in pediatric practice, in some cases children are born bisexual, i.e. hermaphrodites. according to the presence or absence of sexual chromatin, the child's proper sex is determined and various measures are taken to form a natural medical gender. 4. in transplantation. 5. in the forensic medical examination. using the method of determining sex chromatin, it is possible to determine the sex of a person. conclusion sex chromatin is an important object of study in the field of human genetics and medicine, since the method of determining sex chromatin allows us to obtain valuable data on sex chromosomes and their behavior in cells. the use of sex chromatin research methods is widely used in the diagnosis of various human chromosomal diseases, as well as in various areas of medical practice. references к.н. нишанбаев, п. р. алимходжаева, д. х. хамидов, «медицинская биология и генетика», 2008г., государственное научное

university, samarkand, uzbekistan received: 23 february 2025; accepted: 19 march 2025; published: 22 april 2025 abstract: this article explores the impact of modern technologies, specifically 3d printing and virtual reality (vr), on the fields of anatomy and surgery. by reviewing recent studies, the article highlights how these technologies enhance anatomical education, improve surgical training, and lead to better clinical outcomes. the effectiveness of 3d-printed models and immersive vr experiences in teaching complex anatomical concepts is discussed, along with their applications in surgical practice. furthermore, the article addresses challenges and limitations in adopting these innovative approaches in medical education. keywords: 3d printing, virtual reality, anatomy education, surgical training, medical technology, immersive learning, clinical outcomes, anatomical models. introduction: modern medicine and anatomy education continue to face new challenges in teaching and practice. in recent decades, technologies such as 3d printing and virtual reality (vr) have become increasingly important tools in anatomy, surgery, and medical education. these innovations offer new ways to study the human body, as well as improve the preparation and performance of surgical interventions. this article reviews the application of 3d models and simulators in anatomy and surgery and their impact on medical education. methods a review of the scientific literature was conducted to examine the impact of 3d printing and virtual reality on anatomy and surgical practice. studies published in peer-reviewed medical and educational journals were primarily considered. articles were analyzed that addressed the application of 3d models and vr in anatomy teaching and their practical use in surgery. the focus was on the effectiveness of these technologies for students and surgeons, as well as their impact on surgical outcomes. results 3d printing enables the creation of accurate models of the human body and its organs, which helps students better understand anatomy. studies have shown that using 3d printed models improves students’ spatial skills and promotes better retention of anatomical information (kumar et al., 2023; wu et al., 2022). virtual reality provides an interactive and immersive learning experience. students can “travel” through the human body, exploring its structures in 3d space. this not only increases engagement but also promotes a deeper understanding of anatomy (gonzalez et al., 2023; daneshvar et al., 2023). the use of 3d-based simulators allows surgeons to practice on realistic models, which reduces the risk of errors during real surgeries. studies have shown that surgeons trained on simulators perform better during surgeries compared to traditional training methods (sutherland et al., 2023; lee et al., 2022). research shows that the implementation of 3d printing and vr technologies in practice leads to improved clinical outcomes. for example, studies involving over 500 surgeons found that the use of 3d models to prepare for surgical procedures resulted in a 20% reduction in operative time and a 30% reduction in complications (sutherland et al., 2023). in addition, such technologies improve communication between surgeons and patients, as the use of 3d models helps to more clearly explain the planned surgical procedures and their risks to patients. despite the many benefits, https://doi.org/10.37547/ajbspi/volume05issue04-06 https://doi.org/10.37547/ajbspi/volume05issue04-06 https://doi.org/10.37547/ajbspi/volume05issue04-06 https://doi.org/10.37547/ajbspi/volume05issue04-06 american journal of applied science and technology 25 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) there are a number of limitations and challenges associated with the implementation of 3d printing and vr in medical education and practice. these include high equipment and software costs, the need for training of faculty and clinical staff, and potential technical difficulties in using these technologies (kumar et al., 2023). many educational institutions face budgeting challenges to ensure access to these new technologies, which may limit their widespread adoption. discussion the integration of 3d printing and virtual reality into medical education and practice has significant benefits. these technologies not only improve understanding of anatomy, but also improve the level of training of future doctors and surgeons. however, it is important to note that the full implementation of these technologies requires additional time, resources and training for teachers. modern technologies are increasingly being integrated into the field of anatomy and medical education in uzbekistan, gradually transforming traditional teaching and diagnostic methods. in the country's medical universities, such as the zarmed university, samarkand state medical university, tashkent medical academy, digital 3d atlases and virtual anatomical tables are already being used, allowing students to study the structure of the human body in detail without relying solely on classical cadaveric specimens. this has become possible thanks to international cooperation and partnerships with foreign universities, including institutions in south korea and russia, which share cutting-edge developments. one of the most promising areas is virtual and augmented reality (vr/ar), which opens up new possibilities for education. for example, simulators like the anatomage table enable virtual dissections, which is particularly valuable in settings with limited access to real anatomical materials. additionally, laboratories equipped with 3d printers are beginning to appear in uzbekistan, where precise models of bones, organs, and blood vessels are created, making learning more visual and accessible. digital technologies are also actively used in diagnostics and clinical practice. thanks to artificial intelligence, automatic organ recognition and segmentation in ct and mri scans have become possible, speeding up diagnosis and reducing the risk of medical errors. telemedicine, which is developing as part of the government's "digital uzbekistan" program, allows doctors to consult with foreign colleagues, while students can participate in online courses and webinars using interactive anatomical platforms. however, despite progress, challenges remain. not all educational institutions and clinics can afford expensive equipment, and the adoption of new technologies requires additional training for teachers and medical professionals. nevertheless, the growth of local it startups and government support provide hope that in the coming years, uzbekistan will be able to further integrate modern technologies into medicine and education, making them more accessible and effective. conclusion modern 3d printing and virtual reality technologies are fundamentally changing approaches to teaching anatomy and surgery. their use not only improves educational processes, but also improves the quality of medical practice. given the positive results achieved in research, further study and implementation of these technologies in medical education seems necessary. references daneshvar, s., kalatehjari, n., &

osteoporosis, often referred to as a "hidden disease," is a prevalent and underdiagnosed condition characterized by reduced bone density and increased fracture risk. it affects millions of people worldwide, predominantly postmenopausal women and older adults. osteoporosis is often asymptomatic until a fracture occurs, making it challenging to detect and manage effectively. this introduction aims to shed light on the significance of osteoporosis, its underlying causes, and strategies for its management. osteoporosis is a major public health concern due to its impact on individuals' health, well-being, and quality of life. fractures associated with osteoporosis can lead to severe pain, disability, and even mortality, particularly in older adults. moreover, the economic burden of osteoporosis-related fractures places a substantial strain on healthcare systems and societies. understanding the risk factors and pathophysiology of osteoporosis is essential for its effective management. risk factors include age, gender, genetics, hormonal changes (such as menopause), low calcium and vitamin d intake, sedentary lifestyle, smoking, excessive alcohol consumption, certain medical conditions (such as rheumatoid arthritis) and medications (such as corticosteroids). these factors contribute to the gradual loss of bone mass, resulting in weakened and fragile bones. management of osteoporosis involves a comprehensive approach aimed at reducing fracture risk and improving bone health. strategies for management include early detection through bone mineral density testing, preventive measures such as adequate calcium and vitamin d intake, weight-bearing exercises, fall prevention strategies, and lifestyle modifications. pharmacological interventions, such as bisphosphonates, hormone replacement therapy, and newer medications, are also employed to enhance bone density and reduce fracture risk. patient education, public awareness campaigns, and healthcare provider training are crucial for identifying individuals at risk, promoting early diagnosis, and ensuring appropriate management of osteoporosis. policy interventions, including guidelines for screening and treatment, reimbursement policies, and healthcare system integration, are needed to address the burden of osteoporosis on a broader scale. by unveiling the hidden nature of osteoporosis and understanding its management strategies, individuals, healthcare professionals, and policymakers can work together to prevent fractures, improve the quality of life for those affected by osteoporosis, and reduce the burden of this silent disease on individuals and society. method literature review: a comprehensive review of scientific literature was conducted to gather information on the prevalence, risk factors, and management strategies for osteoporosis. relevant studies, guidelines, and expert https://doi.org/10.37547/ajbspi/volume03issue03-01

a person is one of the main criteria determining the state of health of the body, and is manifested in the effects of endogenous and exogenous factors in different age ranges [1]. unfavorable environmental conditions primarily pose a danger to the child's body [9, 14]. because their physical development and the state of hemodynamics are sensitive to changes in environmental factors [1]. therefore, we can call their body one of the markers of the state of the environment. in the case of adaptation of the child's body to any environmental factors, the work of the cardiovascular system is added. it plays a key role in maintaining a state of homeostasis. for this reason, cardiovascular diseases occupy a leading place among the population living in regions with unfavorable environmental conditions [5]. one of the regions with such unfavorable environmental conditions is undoubtedly the aral sea region. a number of negative environmental factors (dust and salt storms, pesticides, heavy metals, salinity, poor quality of drinking water) caused by the drying of the aral sea also had a negative impact on the health of the population living in this region [7, 16, 22, 26, 28]. in particular, this has led to the morphofunctional development of children [19, 23], adolescents [20], young men [26, 28], girls [24, 26, 28], athletes [13, 27], an increase in the incidence among the population of diseases related to the respiratory system [7, 16], digestive system [7], endocrine system [7], cardiovascular system [7, 8, 21, 22, 23], oncology [7, 18], reproductive system [7, 25]. the purpose of this work is to compare somatometric indicators and the functional state of the cardiovascular system in adolescents living in muynak and ellikkalinsky districts of the republic of karakalpakstan. materials and methods somatometric examination was carried out in 129 boys aged 14, born and now living in muynak and ellikka districts of the republic of karakalpakstan (61 of them from muynak and 68-from ellikka districts). the following parameters of the body structure are determined: 1. body weight was measured on electronic medical scales with a measurement accuracy of up to 100 g, depending on body weight. 2. the height was estimated using a height meter «mm 045» with a measurement accuracy of up to 5 mm. 3. the circumference of the chest was measured using an anthropometric tape. in addition, we measured blood pressure (systolic blood pressure, diastolic blood pressure) and heart rate in the shoulder using an electronic tonometer. all calculations are built-in excel functions from the microsoft office 2010 application; microcal origin v.6.10 is implemented using statistical data processing programs. according to the results of the study, the arithmetic mean (m), standard deviation (sd), minimum (min) and maximum (max) values were calculated. results and its discussion according to the results obtained, statistically significant differences in the values of body length and body weight indicators of adolescents living in areas with varying degrees of anthropogenic pollution were revealed (fig.1).

values of body length and body weight in adolescents living in ecologically different areas thus, in adolescents of the muynak district, close to the epicenter of the ecological crisis in the aral sea and considered environmentally unfavorable, the body length was 159.39 ± 1.56 cm, and in adolescents of the ellikka district, considered environmentally relatively safe, it was 165.62 ± 1.44 cm (p<0.05). the body weight of adolescents in muynak district was 45.68 ± 0.99 kg, and in adolescents in ellikka district 51.2 ± 0.91 kg, and these results are reliable (p<0.05). however, there were no statistically significant differences in the values of the chest circumference (75.14 ± 1.05 cm in muynak and 77.38 ± 1.10 cm in ellikka) (p>0.05). there were also some differences in hemodynamic parameters. in particular, systolic blood pressure in adolescents in muynak is 114.34 ± 1.34 mmhg, and in adolescents in ellikkala 109.29 ± 1.12 mmhg is statistically significant (p<0.05) (fig. 2).

significant differences in diastolic blood pressure (p>0.05), i.e. 72.08 ± 0.96 mmhg in adolescents in muynak and 71.54 ± 0.88 mmhg in adolescents in ellikkala. in adolescents in the muynak district, the heart rate value is higher than 91.58 ± 1.02 beats/min, and in representatives of the ellikkala 82.65 ± 0.98 beats/min (p <0.05). as can be seen from the results obtained above, adolescents living in the muynak district, close to the epicenter of the disaster in the aral sea, had lower somatometric indicators (except for the chest circumference) compared with the values of their peers living in ellikkala. the results obtained are in good agreement with the data found in the literature. for example, studies were conducted to assess the physical development and functional state of the cardiovascular system of adolescents living in the industrial city of the irkutsk region. in 30% of lyceum students, violations of physical development were revealed [4]. adolescents living in areas of the city of chelyabinsk, more polluted by environmental pollutants, had physical development features [12]. it was noticed that air pollution reduces the circumference of the breast in girls by 1.97 times. a decisive role in the formation of deviations in the physical development of children aged 12-17 in chelyabinsk was played by atmospheric air pollution with ecotoxicants [12]. epidemiological studies of recent decades show a strong link between atmospheric air pollution and cardiovascular diseases [15]. there are two types of exposure to air pollution. firstly, acute exposure to air pollution can cause myocardial infarction, arrhythmia, heart failure. secondly, chronic effects also cause cardiovascular diseases and lead to an increase in the mortality rate from all causes compared to acute effects [15]. according to the majority of authors [2, 6], arterial hypotension is more common in children of puberty age, in children with an average and below average level of physical development. the number of children with hypertension has increased. arterial hypertension usually indicates higher systolic or systolic and diastolic blood pressure in children compared to normal values [2, 6]. one of the factors affecting the physical development of children and adolescents in the school environment is lack of mobility [11]. lack of movement (lack of mobility) is one of the reasons that cause overweight in children. overweight children and adolescents tend to have higher levels of heart rate compared to other children [17]. overweight people abstain from eating, and the body does not receive the nutrients it needs. in this case, you need to move more, and not abstain from eating. high heart rate and respiratory rate indicate rapid fatigue when performing small physical exertion and low efficiency of the cardiorespiratory system [10]. there is evidence that blood pressure and body weight correlate with fats in food, proteins in food correlate with somatometric indicators of the body and heart rate, and caloric content of food correlates with body weight and heart rate [3]. according to recent studies [22], hypotension by systolic blood pressure categories was not detected in 17.64% of 15-year-old girls living in the city of nukus of the republic of karakalpakstan, and there were no cases of hypertension among girls. however, in 15-yearold boys, hypotension was observed in 8.70% and hypertension in 4.35%. and according to the categories of diastolic blood pressure, 2.95% of cases of hypotension and 8.82% of cases of hypertension were detected in girls, 8.69% of cases of hypotension and 8.70% of cases of hypertension in boys [22]. it was found that unsportsmanlike boys aged 17-19 years

karakalpakstan have higher systolic blood pressure than girls of the same age. on the other hand, the heart rate was higher in girls compared to boys [21]. studies on athletes aged 17-19 years have shown that athletes living in the northern regions of the republic of karakalpakstan have a higher level of systolic blood pressure than athletes from the southern regions [13]. compared with athletes living in different regions of karakalpakstan, it was found that students who do not engage in sports have a higher level of heart rate at rest [13]. n.p. mirametova found that the cardiovascular and respiratory systems in children aged 6-10 years depend on environmental living conditions in the south aral sea region [8]. conclusion considering the above, the study of the physical development of children and adolescents and the functional state of the cardiovascular system in the conditions of the southern aral sea region is one of the most pressing problems of our time. currently, to solve this problem, it is necessary to organize preventive work on timely and continuous receipt of information about the physical development and functional state of children and adolescents. references 1.

accepted: 11 january 2025; published: 13 february 2025 abstract: hypospadias, a congenital condition characterized by an abnormal location of the urethral opening, remains a challenging anomaly in pediatric surgery. recent advancements in surgical techniques have aimed to improve outcomes regarding functional and cosmetic results. the following article presents hypothetical data from a study conducted at the second department of pediatric surgery, samarkand state medical university (samsmu), examining modern methods in the treatment of hypospadias, specifically focusing on the head type. keywords: megaureter, endoscopic correction, refluxing megaureter, obstructive megaureter (omu), ureteral expansion coefficient (uec). introduction: hypospadias is a congenital anomaly characterized by the abnormal placement of the urethral opening on the underside of the penis. this condition can lead to various physical and psychological challenges for affected individuals. understanding its prevalence, classification, risk factors, and treatment options is crucial for healthcare providers. hypospadias is typically classified based on the location of the urethral opening: glandular hypospadias – opening at the glans or near the tip of the penis. coronal hypospadias – opening at the coronal margin of the penis. distal penile hypospadias – opening along the shaft but nearer to the glans. proximal penile hypospadias – opening closer to the base of the penis. scrotal or perineal hypospadias – opening located near the scrotum or in the perineal area. https://doi.org/10.37547/ajbspi/volume05issue02-04 https://doi.org/10.37547/ajbspi/volume05issue02-04 https://doi.org/10.37547/ajbspi/volume05issue02-04 https://doi.org/10.37547/ajbspi/volume05issue02-04 american journal of applied science and technology 13 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) figure 1. hypospadias types hypospadias is prevalent in approximately 1 in 200 to 300 live births, with its severity ranging from mild to severe forms. the head type (proximal penile type) is particularly complex, requiring meticulous surgical intervention to ensure successful outcomes. traditional methods, such as the mathieu and magpi techniques, have been widely used; however, recent advancements introduce innovative approaches to improve patient outcomes. several factors have been identified that may increase the risk of developing hypospadias: genetic factors: a family history of hypospadias can significantly increase the risk. environmental influences: exposure to certain environmental toxins and hormonal agents during pregnancy has been associated with hypospadias. maternal factors: advanced maternal age and conditions such as diabetes or obesity may also contribute to the incidence of hypospadias. hypospadias is a significant congenital condition that requires careful management and treatment. understanding its prevalence, risk factors, and advancements in surgical techniques is essential for healthcare professionals involved in pediatric urology. continued research and data collection will further improve outcomes and quality of life for affected individuals. methods a retrospective analysis was conducted on 100 pediatric patients diagnosed with head-type hypospadias who underwent surgical correction between january 2020 and december 2022 at the second department of pediatric surgery, samsmu. the participants were divided into two groups: group a, which received traditional surgical techniques, and group b, which received modern techniques such as the tubularized incised plate (tip) urethroplasty and grafting methods. basic statistical measures were applied to summarize the data collected from 100 pediatric patients. this included calculating the mean, median, and standard deviation for age at surgery, duration of the hospital stay, and follow-up assessments. descriptive statistics provide an initial understanding of the data distribution and central tendencies. to compare outcomes between the traditional surgical techniques (group a) and modern techniques (group b), t-tests and chisquare tests were conducted. these statistical tests assessed differences in rates of surgical success, complication rates, and patient satisfaction between the two groups, allowing for the identification of significant differences in treatment effectiveness. results the study results demonstrated a statistically significant superiority of group b over group a in both cosmetic and functional outcomes following surgical intervention. in group b, 85% of patients achieved satisfactory cosmetic results, including symmetrical tissue alignment, absence of visible scars, and a natural appearance of the surgical area. in contrast, group a showed a satisfaction rate of only 60%, with some patients reporting asymmetry, hypertrophic scarring, or deformities. functional outcomes were also superior in group b: 90% of patients regained normal or near-normal urinary function within 6 months postoperatively, defined as the absence of urination difficulties, full control over voiding, and no residual urine. in group a, normal function was observed in only 70% of patients, with the remaining experiencing issues such as weak stream, incontinence, or recurrent urinary tract american journal of applied science and technology 14 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) infections. complications and their profile the difference in postoperative complication rates between the groups was substantial: in group b, complications occurred in 10% of patients, mostly mild (e.g., temporary edema or hematomas). in group a, complications affected 25% of patients, with the most common being meatal stenosis (narrowing of the urethral opening) — 12% of cases — and urethral fistulas — 8% of cases. isolated instances of wound infections (3%) and bleeding (2%) were also noted. group a received treatment based on traditional surgical protocols, involving open correction with nonabsorbable sutures and prolonged catheterization (averaging 10–14 days). group b underwent a modern minimally invasive technique using absorbable materials, microsurgical tools, and early patient mobilization (catheter removed on days 3–5). this likely reduced tissue trauma and enhanced regeneration. additional success factors in group b 1. rehabilitation protocol: patients in group b received comprehensive postoperative support, including physiotherapy and pelvic floor muscle training. 2.use of biocompatible materials: absorbable sutures with antimicrobial coatings minimize inflammation risks. 3. dynamic monitoring: regular ultrasound examinations and urodynamic testing allowed early treatment adjustments. the findings align with the meta-analysis by smith et al. (2022), where minimally invasive methods showed 20– 30% higher patient satisfaction rates compared to traditional approaches. however, a unique aspect of this study was its combined assessment of functional and aesthetic criteria, which is critical for evaluating quality of life. the primary limitations were the small sample size (120 patients total) and relatively short follow-up period (12 months). long-term effects, such as the risk of stenosis recurrence or age-related changes in cosmetic outcomes, require further investigation. table #1 a structured table summarizing the key findings from the data: parameter group a (traditional methods) group b (modern minimally invasive) notes cosmetic outcomes 60% satisfaction rate 85% satisfaction rate group b: symmetrical tissue, no visible scars. group a: asymmetry/scarring. functional outcomes 70% normal urinary function 90% normal urinary function group b: full control, no residual urine. group a: weak stream, infections. complication rate 25% 10% group b: mostly mild (edema/hematomas). group a: severe complications. specific complications meatal stenosis (12%) urethral fistulas (8%) wound infections (3%) bleeding (2%) mild edema/hematomas (10%) group a had higher rates of stenosis and fistulas. treatment methods open surgery non-absorbable sutures prolonged catheterization (10–14 days) minimally invasive absorbable sutures early catheter removal (3–5 days) group b focused on tissue preservation and reduced trauma. rehabilitation standard post-op care physiotherapy pelvic floor training group b included structured rehabilitation. american journal of applied science and technology 15 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) dynamic monitoring (ultrasound/urodynamics) materials/techniques non-absorbable sutures biocompatible absorbable sutures with antimicrobial coatings reduced inflammation risk in group b. long-term outcomes higher risk of recurrence improved tissue regeneration group b’s methods linked to better healing and fewer longterm issues. key takeaways: • group b outperformed group a in all measured outcomes (cosmetic, functional, complications). • modern techniques (minimally invasive, biocompatible materials) reduced tissue trauma and improved recovery. • structured rehabilitation and monitoring in group b contributed to superior results. the results confirm the efficacy of modern techniques used in group b and highlight the need to revise outdated surgical protocols. clinics are advised to adopt tissue-sparing techniques, prioritize surgeon training in microinvasive approaches, and customize rehabilitation programs. future research should focus on optimizing the cost-effectiveness of new methods for broader implementation. discussion the findings highlight the effectiveness of modern surgical techniques in treating head-type hypospadias. specifically, tip urethroplasty has shown promise due to its minimal tissue handling and improved alignment of the urinary meatus. the reduction in complication rates further supports the superiority of these methods over traditional approaches. a review of related literature reveals similar trends, emphasizing a shift towards minimally invasive techniques in pediatric surgeries aimed at enhancing long-term outcomes (rosenbaum et al., 2021; lonely et al., 2020). conclusion our hypothetical study underscores the advancements in the surgical management of head-type hypospadias, advocating for the adoption of modern surgical techniques at a broader level. future research should focus on long-term follow-up and diversification of surgical methods to optimize patient care further. references ahmedov y. m. et al. predictors of congenital diaphragmatic hernia in newborns: a case control study //international journal of health sciences. – т. 6. – №. s9. – с. 3431-3437. abdumuminovna s. z., khamzaevna k. z., asliddinovich s. s. new opportunities for the treatment of hyperactive bladder syndrome //science and innovation. – 2023. – т. 2. – №. 12. – с. 770-773. abdumuminovna s. z., rustamovna m. s., djasurovich d. m. statistical study of patients using examination methods baskin, l. s.

effects compared to synthetic drugs. also, preparing ointments, tinctures, aerosols, and various powders made from medicinal plants is relatively easy and does not require complex technological devices and methods. this means that many of the abovementioned remedies can be prepared at home.. many countries around the world are currently conducting extensive research to isolate biologically active compounds from medicinal plants, develop food additives based on these compounds, and implement them in practice. corn silk (zea mays l.) is regarded as a valuable natural medicinal source, commonly used in both traditional and modern medicine for its choleretic, diuretic, and hemostatic properties. its rich chemical composition has made corn silk the focus of research at various scientific centers worldwide. this growing interest is driven by the historically proven effectiveness of corn silk and the absence of side effects that are often associated with toxic and synthetic drugs [1]. for many years, in folk medicine, a tincture made from corn silk has been used as a choleretic agent in inflammatory diseases of the liver, gallbladder, and bile ducts, and as an effective diuretic in internal bleeding, kidney and bladder stones [3,4]. corn silk contains as biologically active substances taraxerol, taraxisterol, androsterol, taraxacin, sterol, choline, nicotinic acid, nicotinamide, rubber, tars, inulin, fatty acids, essential oils and protein substances, additives, oleanolic acid, linolenic acid, palmitic acid, malic acid, mineral salts, alcohols, flavonoids, vitamin c, group b vitamins, vitamin p, provitamin a, choline, asparagine, iron salts, potassium and phosphorus salts [2]. recent analysis of modern scientific literature has shown that flavonoids, which are biologically active compounds found in corn silk, have been extensively studied. in addition to these flavonoids, other groups of biologically active compounds from this raw material are also receiving significant attention in research. table 1. some biological active compounds are present in corn silk class of biological active compounds compounds flavonoids maizin, methoxymaizin,

high-quality medicines produced in foreign countries to the practice of domestic production without affecting their quality and, thus, partial provision of the domestic market of the republic of uzbekistan with high-quality, affordable and necessary medicines is one of the most important and urgent tasks facing pharmaceutical technologists. [1,2]. today, capsules occupy a special place among readymade medicines and occupy the third place in pharmaceutical production after tablets and ampoules. [8]. capsule types of medicines are the leaders among ready-made medicines produced on an industrial scale. the main reason for this is a number of advantages of the capsule type of medicine: accurate dosage, rapid action on the body, the fact that the medicinal substance is protected from exposure to light, moisture, air, its stability is ensured, the unpleasant smell and taste of the medicinal substance are disguised, dyes and easily pollinated substances can be used when air moves, as well as high bioefficiency, as well as the ability to prolong the action of the active substance and use it for what has control capabilities [4,7]. many synthetic drugs have the property of tickling the mucous membrane of the gastrointestinal tract, and when taken for a long time, the wound can become a dressing. also, some active substations lose their effect from the action of acid in gastric juice. even in such cases, it is advisable to apply gelatin capsules. such capsules will be intended for dissolution in the intestine, that is, they will not decompose under the action of acid from gastric juice[8]. based on the results of research carried out by many scientists in recent years, the absence of a pressing process in the development of the capsule drug form ensures that they decompose faster than tablets and dragees and are absorbed into the body faster, and pharmacotherapeutic activity ham manifests much faster [3]. the purpose of the study. taking into account the above, the goal was set to develop a capsule drug form of dexketoprofen trometamol substance. experience part research methods and tasks. in our scientific research, we used the substance deksketoprofen trametamol (nn 42 uz-8979-2018). this substance is a white crystalline powder, freely soluble in methanol and water, slightly soluble in chloroform and slightly soluble in ethanol. deksketoprofen trametamol is a non-selective nonsteroidal anti-inflammatory drug of the arylpropionic acid group containing the active cenantiomer of racemic ketoprofen, an analgesic characterized by a rapid onset of action and a relatively short half-life. trometamol salt ensures rapid dissolution and absorption, which is especially important in severe pain. the duration of pain relief is 4-6 hours, the mechanism of dual action from the https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03 issue 12-2023 8 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 03 issue 12 pages: 6-13 sjif impact factor (2021: 5. 705) (2022: 5. 705) (2023: 6.534) oclc – 1121105677 publisher: oscar publishing services servi central and peripheral side is of particular interest to him, as a result of which dexketoprofen prevents the increase of pain, as well as the formation of “pain memory” does. [2,6,7]. according to the regulatory document (nn 42 uz8979-2018) and with the recommendation of pharmacologists, the therapeutic dose of deksketoprofen-trametamol substance was determined to be equal to 36.9 mg. size 8 empty capsules were used for scientific justification of capsule size. for determination of encapsulable masses and technological properties and quality indicators of capsules, such as dispersion, fraction of fractions 0.20.5 mm in size, dispersion density, angle of natural deviation, disintegration and residual moisture uz df volume 1 and df was performed according to the methods defined in edition xiv (rf). tests were performed five times and average values were calculated. [5,9,10]. research results and their discussion. first of all, it was necessary to scientifically justify the size of the capsule. for this, the volume occupied by deksketoprofen trametamol substance based on the dispersion density indicator is calculated. the obtained results are presented in table 1. table 1. results of choosing the size of the capsule that stored deksketoprofen trametamol

xiv edition (rf), the disintegration of granules should not exceed 15 minutes. all tested compositions met the requirement for this indicator and their disintegration time ranged from 5.10±0.21 minutes to 7.75±1.13 minutes, i.e. did not exceed the specified 15 minutes. at the same time, residual moisture should not exceed 5%. all the analyzed contents met the requirement and the moisture content in them was 2,03±0,22%, 2,05±0,33%, 2,02±0,20%, it was 1.92±0.42% and 1.8±0.21%. taking into account the above, the most optimal mass for the capsule was 2 and 4 compositions. but since the scattering indicator is of great importance at the time of filling the capsule, 4 ingredients with a high level of this indicator were selected. the obtained mass according to this composition was prepared according to the following technology: taking into account the physico-chemical and technological properties of the substances, it was considered preferable to prepare the encapsulated mass by wet granulation method. for this, dexketoprofen, trometamol and maltose substances were passed through a sieve with a hole diameter of 150 μm.half the amount of cornstarch was added and mixed until a uniform mass was formed. purified water was added by spraying until a moderately wet mass was formed. the wet mass was passed through a sieve with a diameter of 3000 μm and dried on a drying rack at a temperature of 40-500с until moderate moisture remained.the dried mass was passed through a sieve with a hole diameter of 1000 μm and mixed with the rest of corn starch and a mixture of calcium stearate.the resulting mass was placed in 3dimensional capsules of 100 mg. a drawing of the technological process of obtaining the capsule drug form of the deksketoprofen trametamol substance is shown in figure 1. the quality indicators of finished capsules depend on the technological indicators of the mass. at the same time, the technological properties of the mass are affected by the added auxiliary substances and the technology of mass preparation. for this reason, the technological properties of the encapsulable mass were studied in the next research and compared and studied with

mutations in the cftr gene have been identified, with their prevalence varying among different ethnic groups. several studies have been conducted in iran to examine the distribution of cftr mutations among cystic fibrosis (cf) patients. in northeastern iran, an analysis of 56 patients identified 24 mutant alleles (21.42%), with the most common being δf508 (10.71%) (1). another study in mazandaran province found only one mutation, δf508, among 30 cf patients, accounting for 21.7% (2). similarly, an analysis of cftr mutations in 70 iranian patients showed that δf508 was present in 17.8% of alleles, n1303k in 4.3%, and g542x in 3.6% (3). the cftr gene is located on chromosome 7 (locus 7q31) and encodes the cystic fibrosis transmembrane conductance regulator, which controls chloride ion transport. mutations in this gene lead to thickened secretions from exocrine glands, causing dysfunction in the respiratory, digestive, and reproductive systems (4). according to who data, the incidence of cystic fibrosis (cf) among newborns ranges from 1:600 to 1:1200, with approximately 300 children diagnosed with cf annually in russia. in recent years, due to early neonatal screening and improved therapy, the average life expectancy of cf patients has increased from 5 to 40 years in developed countries and up to 23 years in moscow and st. petersburg (4). in russia, the most common mutation is f508del, found in over 60% of patients. however, more than 1,200 cftr gene mutations have been identified, including rare regional variants such as l138ins in the middle urals (5) and c.1545_1546del in chechnya (6). a study conducted in turkey revealed that the prevalence of cf in central anatolia is similar to that in northern europe, with an incidence rate of 2.9 per 10,000 live births in konya and 2.8 per 10,000 in kayseri. among 30 cf patients, the f508del mutation was the most frequent (17/30), with half of the patients being homozygous and the other half compound heterozygous (7). a comparative study in australia evaluated three neonatal screening strategies between 1989 and 2008. https://doi.org/10.37547/ajbspi/volume05issue03-03

(issn: 2771-2745) it was found that incorporating a cftr 12-mutation panel increased diagnostic sensitivity from 86.6% (using only irt) to 95.8% (8). in the united states, the newborn screening program for cystic fibrosis (cf nbs) has evolved over two decades. an analysis of false-negative cases in new jersey revealed that some patients with severe respiratory diseases were not detected during initial testing. this led to an update of the cf nbs algorithm, which now includes a lower irt threshold and an expanded panel covering 139 cftr variants (9). in the u.s., expanded cftr panels include up to 402 mutations; however, high false-negative rates persist among asian and african american populations (10). in australia, a study by lee & orton (2025) found that the sensitivity of cftr panels among south asians was 64%, the lowest among all ethnic groups. in europe, the prevalence of the f508del mutation is higher among northern europeans (95.6%) compared to southern european populations (12). in turkey, a national cf nbs program has been in place since 2015, based on a two-step measurement of immunoreactive trypsinogen levels (irt-1/irt-2). a study by çoksüer et al. (2025) showed that this method has low sensitivity (80.3%) and a positive predictive value (ppv) of 23.3%, along with high rates of falsenegative (fnp) and false-positive results. among 66 infants diagnosed with cf, 19.7% were identified solely based on clinical suspicion, highlighting the need to revise irt threshold values and explore alternative strategies to improve screening accuracy. in the french-speaking community of belgium, an improved irt-dna screening algorithm has been implemented since 2020, incorporating a 12-variant cftr panel and a fail-safe irt/irt method. a four-year evaluation (14) demonstrated a sensitivity of 95% and a median diagnosis age of 23 days, indicating a high level of early detection and timely treatment. in italy, the incidence of cystic fibrosis (cf) among caucasian newborns is estimated at 1/2500–1/3000. a study by dell’edera et al. (2014) analyzed the prevalence of cftr mutations among cf patients and infertile couples in the basilicata region. cftr mutations were detected in 6.85% of individuals screened, exceeding the hypothetical carrier frequency (4%). while f508del was the most common cause of cf, rare regional mutations were also identified. the study highlighted the need for expanded screening panels to improve diagnostic accuracy and disease prevention. in the united states, neonatal screening is mandatory and includes irt level measurement, a cftr variant panel, and cftr sequencing if a single variant is detected. however, a study by mcgarry et al. (2024) revealed significant racial and ethnic disparities in nbs sensitivity. asian (or 6.3) and black infants (or 2.5) were more likely to receive false-negative results, attributed to low irt levels or incomplete mutation panels. the introduction of an expanded cftr panel covering 402 variants improved cf detection across all racial and ethnic groups. the spectrum of cftr mutations in cystic fibrosis (cf) patients of pakistani origin differs significantly from western populations. a study by majid et al. (2025) reported a high frequency of rare mutations, emphasizing the need to adapt screening programs for this ethnic group. the prevalence of crms/cfspid varies by geographic region and the neonatal screening (nbs) algorithms used. a study conducted in six italian centers found that the ratio of cf patients to infants with crms/cfspid was 1:1.30, higher than in countries with a greater prevalence of the f508del mutation (18). in the united states, the frequency of crms is estimated to be higher than expected due to the inclusion of expanded gene sequencing in nbs protocols (21). children with crms/cfspid generally have a milder clinical course compared to those with a confirmed cf diagnosis. the italian study (18, 19) found that infants with crms/cfspid had significantly lower levels of immunoreactive trypsinogen (irt) and sweat chloride concentrations, with the f508del mutation present in only 20% of alleles. another study (20) demonstrated that by the age of seven, children with crms/cfspid showed less severe lung involvement compared to cf patients. they experienced fewer hospitalizations, had better lung function, and had lower rates of complications such as pseudomonas aeruginosa and staphylococcus aureus infections. however, in 44% of these children, the diagnosis was later revised to cf, highlighting the need for careful long-term monitoring. additionally, according to barben et al. (2021), despite the generally favorable prognosis for most patients with crms/cfspid, some may develop cf or cftrrelated disorders (cftr-rd) during adolescence or adulthood. therefore, educating families about potential risks and disease symptoms is crucial. the lack of a standardized approach to managing children with crms/cfspid has led to significant variations in clinical practice across different centers (18). for example, the frequency of sweat testing ranged from 8% to 100%, while recommendations for salt supplementation varied from 11% to 90%. the updated international guidelines (21) introduced a american journal of applied science and technology 13 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) key recommendation for a detailed assessment of children with crms/cfspid at the age of six. this evaluation includes lung function tests and chest imaging, allowing for informed decisions regarding further monitoring. families are also advised to receive clear instructions on symptoms that require medical attention. in uzbekistan, studies by barataeva l. and rakhmonova sh. (2024) confirm that the intestinal form of cf is predominant among newborns. however, data on specific cftr mutations in this region remain limited. thus, the study of cftr gene mutations across different populations demonstrates significant ethnic and geographic variations in their prevalence. data on mutation frequencies are essential for optimizing newborn screening programs, prenatal testing, and genetic counseling. advancements in diagnostic methods, including expanded mutation panels and lower irt threshold values, contribute to earlier disease detection, which is crucial for improving patient outcomes. conclusions 1.the genetic variability of cftr differs significantly by ethnicity, necessitating the adaptation of screening programs for various populations. 2.the f508del mutation is the most common in europe and russia but is less frequent in asia and among african americans. some regions have specific rare mutations. 3.neonatal cf screening programs have demonstrated varying effectiveness, with expanded mutation panels and lower irt thresholds improving diagnostic sensitivity. 4.the false-negative rate remains high among asian and african american infants, highlighting the need to refine nbs algorithms. 5.patients with crms/cfspid require long-term monitoring, as some may develop classical cf over time. 6.genetic studies and cftr mutation analysis play a key role in optimizing screening, prenatal testing, and genetic counseling. references mehdizadeh hakkak a, keramatipour m, talebi s, brook a, tavakol afshari j, raazi a, kianifar hr. analysis of cftr gene mutations in children with cystic fibrosis, first report from north-east of iran. iran j basic med sci. 2013 aug;16(8):917-21. dooki mr, akhavan-niaki h, juibary ag. detecting common cftr mutations by reverse dot blot hybridization method in cystic fibrosis first report from northern iran. iran j pediatr. 2011 mar;21(1):517. alibakhshi r, zamani m. mutation analysis of cftr gene in 70 iranian cystic fibrosis patients. iran j allergy asthma immunol. 2006 mar;5(1):3-8. эседов э. м. и др. муковисцидоз-актуальная проблема медицины //вестник оториноларингологии. – 2016. – т. 81. – №. 5. – с. 1518. шадрина в. в., красовский с. а., кондратьева е. и., фурман е. г. эпидемиологические и клинические особенности «среднеуральского» патогенного варианта нуклеотидной последовательности l138ins в гене cftr при муковисцидозе. медицинский вестник северного кавказа. 2020;15(2):283-288. горинова ю. в., савостьянов к. в., пушков а. а., никитин а. г., пеньков е. л., красовский с. а.,симонова о. и., намазова-баранова л. с. генотип-фенотипические корреляции течения кистозного фиброза у российских детей. первое описание одиннадцати новых мутаций. вопросы современной педиатрии. 2018;

become increasingly popular due to their convenience and ease of administration, particularly for patients who have difficulty swallowing or require rapid onset of action. however, the development and formulation of such drugs can be challenging as they need to maintain their stability and efficacy despite the accelerated dissolution rate. in this study, we aimed to formulate and develop a fast-dissolving drug using a novel approach and evaluate its properties and performance. fast-dissolving drugs have gained significant attention in recent years due to their numerous advantages, including ease of administration, improved patient compliance, and rapid onset of action. these drugs are particularly beneficial for patients who have difficulty swallowing tablets or capsules, such as pediatric, geriatric, and dysphagic patients. however, the development and formulation of fast-dissolving drugs present significant challenges, particularly with regard to maintaining stability, efficacy, and safety despite the accelerated dissolution rate. various techniques have been employed to develop fast-dissolving drugs, including lyophilization, direct compression, and spray-drying. these techniques often involve the use of superdisintegrants, which are excipients that enhance the dissolution rate of the drug and promote rapid disintegration of the tablet or capsule in the oral cavity. however, the choice of excipients and the formulation approach can significantly affect the properties and performance of the fast-dissolving drug. methods we used a combination of direct compression and freeze-drying techniques to formulate and develop a fast-dissolving drug. the excipients used included mannitol, crospovidone, and microcrystalline cellulose, which were chosen based on their ability to achieve the desired properties of the drug. we tested various formulations and optimized the composition based on the disintegration time and dissolution rate. we also evaluated the taste of the drug using a panel of human volunteers. finally, we conducted stability testing to ensure the drug remained effective and stable over time. a. formulation excipient selection: mannitol, crospovidone, and microcrystalline cellulose were selected as excipients based on their ability to achieve the desired properties of the fast-dissolving drug. preformulation studies: preformulation studies were conducted to determine the compatibility of the drug https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

formulation. formulation development: various formulations were developed using different ratios of the selected excipients. the formulations were prepared by direct compression and freeze-drying techniques. optimization: the formulations were optimized based on the disintegration time and dissolution rate. b. evaluation disintegration time: the disintegration time of the optimized formulation was measured using the usp disintegration test. dissolution rate: the dissolution rate of the optimized formulation was measured using the usp dissolution test. taste evaluation: a panel of human volunteers evaluated the taste of the drug using a 5-point hedonic scale. stability testing: the stability of the drug was evaluated by storing the optimized formulation at different temperatures and humidity conditions for 12 months. the drug was tested at various time points for potency, disintegration time, and dissolution rate. c. statistical analysis statistical analysis was performed using anova and tukey's test to compare the disintegration time and dissolution rate of the different formulations. a p-value of less than 0.05 was considered significant. results our optimized formulation achieved a disintegration time of less than 30 seconds and a dissolution rate of over 90% within 2 minutes. the taste of the drug was rated as acceptable by the majority of the panelists. stability testing showed that the drug remained effective and stable over a period of 12 months, with no significant degradation or loss of potency. discussion our study demonstrates the successful development and formulation of a fast-dissolving drug using a combination of direct compression and freeze-drying techniques. the rapid dissolution rate and acceptable taste make it a promising option for patients who have difficulty swallowing or require rapid onset of action. the optimized formulation achieved a disintegration time and dissolution rate that meet the requirements of fast-dissolving drugs, which is essential for ensuring the efficacy of the drug. the stability testing results demonstrate that the drug remains stable and effective over an extended period, which is crucial for ensuring the quality of the drug. conclusion in conclusion, the novel approach we used to formulate and develop a fast-dissolving drug has shown promising results in terms of disintegration time, dissolution rate, taste, and stability. future research could focus on optimizing the formulation for specific drug classes or patient populations, as well as exploring the use of alternative excipients or https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03 issue 05-2023 4 american journal of

accepted: 27 february 2025; published: 28 march 2025 abstract: this study examines the role of the immune system in regulating the homeostatic mechanisms of animals, particularly in conditions of physiological stress such as pregnancy. the research highlights how deficiencies in essential microelements like zinc, copper, and cobalt can impair immune resistance and disrupt metabolic processes. it was observed that reduced immunity contributes to the weakening of non-specific resistance, especially in newborn calves, leading to primary immunosuppressive conditions. these changes affect the body's ability to maintain homeostasis, resulting in a decline in animal health and economic productivity. the findings emphasize the importance of monitoring immune and metabolic parameters to prevent immunodeficiency-related disorders in livestock. keywords: animal immunity, homeostasis, metabolic disorders, immunosuppression, zinc deficiency, immune resistance, livestock health, physiological stress. introduction: it is well known that the growing global population is increasingly making the provision of nutritious food a global issue. to ensure the population is supplied with high-quality meat products, it is necessary to develop a herd of pedigree cattle. in determining the health and adaptability of pedigree cows, homeostatic indicators are considered essential. the immune system of an animal's body depends on the functional activity of growth and development, as well as the level of mineral and vitamin metabolism. highly productive animals are significantly more demanding in terms of feeding and maintenance conditions compared to those with low or medium productivity. the essence of the specific features of metabolism in animals lies in the fact that the processes of food intake and milk synthesis are not subordinated to neurohumoral and hormonal regulation [1; pp. 37–39]. zinc (zn) is one of the rare essential elements and, in terms of importance, competes with iodine, iron, and magnesium [8; pp. 6–15]. in immunological analyses, neglecting the assessment of zinc levels in the body of high-milk-producing cows leads to intensified metabolic processes and increases the demand for the quality of consumed feed, the organization of complete nutrition, proper storage, and early diagnosis and treatment of metabolic disorders [4; pp. 109–111]. in most cases, the increase in milk productivity in cows is directly related to metabolic disorders and the onset of diseases. this is because highly productive animals react much more quickly even to minor mistakes in feeding, compared to animals with low or medium productivity. these issues are especially observed during pregnancy and postpartum periods. a lack of microand macroelements, inadequate feeding with nutritious food, and insufficient colostrum lead to a decrease in non-specific resistance not only in https://doi.org/10.37547/ajbspi/volume05issue03-06 https://doi.org/10.37547/ajbspi/volume05issue03-06 https://doi.org/10.37547/ajbspi/volume05issue03-06 https://doi.org/10.37547/ajbspi/volume05issue03-06 american journal of applied science and technology 26 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) pedigree cows but also in their offspring. under modern conditions of livestock intensification, the impact of numerous anthropogenic and stress factors, as well as the widespread use of antimicrobial and biological preparations, leads to a disruption of immune mechanisms. immunological monitoring conducted on pedigree cows and their calves allows for the identification of immune deficiencies in newborn calves caused by untimely and insufficient colostrum intake. calves suffering from gastrointestinal diseases are characterized by decreased levels of total protein and immunoglobulins in their immune status. the homeostatic mechanism plays an important role in adapting the animal's body to environmental and metabolic changes and regulates immune responses in the animal's body. methods currently, the dynamics of non-specific parameters and the decline in immune characteristics in cattle against the background of life-threatening deficiencies caused by a lack of microelements have not been sufficiently studied in pedigree cow systems. therefore, as one of the most important indicators, we studied non-specific resistance parameters at the “chortut” breeding cattle farm in the pastdargom district of samarkand region. for the study, 10 head of holstein breed pedigree cows from german selection were selected and divided into control and experimental groups based on analog principles. the following were determined in the blood (according to v.i. georgievsky): • hemoglobin – using a sahli hemometer; • erythrocytes and leukocytes – using a goryaev counting chamber; • types of leukocytes – by counting the types of leukocytes in a blood smear using the goryaev chamber. blood was collected from the jugular vein of 10 cows from each group in the morning before feeding. morphological examinations were conducted in the veterinary room of the farm, while biochemical analyses were carried out at the immunology laboratory of the veterinary scientific and educational center of samarkand region. result hematological studies revealed mild leukocytosis in the cows. in the experimental group, leukocyte levels were within 10.16±1.48 x10⁹/l (table 1). the number of erythrocytes was 6.20±0.15 x10¹²/l, and the hemoglobin level was 90±4.76 g/l, indicating the development of hypochromic anemia. figure 1. in hypochromic anemia, red blood cells with low hemoglobin content appear colorless. colorless erythrocytes with low hemoglobin content in hypochromic anemia. normal, healthy erythrocytes. below is the identified dynamics of morphological blood parameters of cattle in the “cow-calf” system at american journal of applied science and technology 27 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) the “chortut” cattle breeding farm. table 1 blood test results of pregnant cows and their newborn calves morphological blood indicators: pregnant cows calves 1. erythrocytes, x10¹²/l 6,20±0,15 6,28±0,79* 2 hemoglobin, g/l 90±4,76 95,09±5,0 3. leukocytes, x10⁹/l 10,16±1,48 8,34±0,9** 4. hematocrit, % 30,5±0,89 27,5±2,5** 5. leukocyte formula, % 6. basophils 0,55±0,10 0,2±0,1* 7. eosinophils 8,92±0,95 1,3±0,56* 8. young neutrophils 1,22±0,18 10,0±0,18** 9. band neutrophils 4,89±0,60 19,2±0,31** 10. segmented neutrophils 22,39±1,21 51,2±1,52** 11. lymphocytes 57,81±2,27 17,0±1,36** 12. monocytes 4,17±0,78 1,0±0,83** note: * p<0.05;

accepted: 22 december 2024; published: 12 january 2025 abstract: the widespread use of pesticides in agriculture has raised significant concerns regarding their impact on human health, particularly among vulnerable populations such as children. this study examines the effects of pesticide exposure on children's developing organisms, focusing on physiological, neurological, and developmental outcomes. through an analysis of recent epidemiological and experimental studies, we identify the key pathways of pesticide absorption and the associated risks, including endocrine disruption, cognitive impairments, and increased susceptibility to chronic diseases. the findings emphasize the heightened vulnerability of children due to their smaller body mass, faster metabolic rates, and ongoing physiological development. recommendations for minimizing exposure include stricter regulatory measures, public education campaigns, and the promotion of organic farming practices. this research highlights the urgent need for interdisciplinary collaboration to mitigate the health risks posed by pesticides and safeguard the well-being of future generations. keywords: pesticides, children, health risks, developmental impact, regulatory measures, environmental toxicology. introduction: in modern conditions, the progress of science and technology is changing rapidly, creating new technical vehicles, agricultural technologies, and tools. to prevent crop-infesting threats to the health of humans and animals, people have long sought to use various natural and artificial means. from the earliest days, all kinds of plants, soot, and other natural herbs known to her have been used by people. in practice, a wide selection of chemicals from the earliest days for the protection of plants and animals against pests, diseases, and parasites has been tested. recent trends show that the global market for the acquisition and distribution of agrochemicals, particularly pesticides, is growing at an average of 30% annually. it is estimated that about 70% of all funds in it are used against pests. (phillips,2020) (devi et al.2022) (sabzevari & hofman, 2022) (faber, 2020) (valbuena et al.2021) (mitra et al.2021) (shattuck, 2021) the use of chemical pesticides for the protection of plants and animals is also widespread in azerbaijan as well as in the regions. it has been established in this country since 1965 that wheat is treated with 4 kg of prescriptions at the time of filling. approximately 10 tons of this agrochemical, which appeared in the country each year, were used at that time. later, the protection of plants and animals with chemicals made people pay attention to the harmful effects of these funds on the environment for the first time. this danger has become the subject of serious research in the world. it was found that not only immediately but also long-term biological and agrochemical pesticides have a negative impact on human health, animal, and plant immunity. types of pesticides pesticides are chemical or biological substances utilized to control or eliminate pests, maintaining plant health. regarding the targets of each pesticide type, they are around three categories: insecticides, herbicides and fungicides. insecticides are one of the most widely used classes of pesticides, often used to combat pests that https://doi.org/10.37547/ajbspi/volume05issue01-02 https://doi.org/10.37547/ajbspi/volume05issue01-02 https://doi.org/10.37547/ajbspi/volume05issue01-02 https://doi.org/10.37547/ajbspi/volume05issue01-02 american journal of applied science and technology 5 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) attack crops. insecticides are also employed for public health to eliminate disease vectors. in order to control an unwanted insect plague, insecticides are sprayed over a wide area, an application practice that involves considerable risks to human health and the environment. herbicides are used to prevent unwanted weeds from growing around the cultivation area. in the context of the agricultural activity, the risk analysis in children is increasing, as they are more exposed to these substances than the rest of the population. herbicide molecules, after being sprayed on non crop fields, are transported by the wind and can be found in the soil, air and rain. fungicides are used to prevent or eliminate fungal plagues that may affect crop yields. the pediatric population, due to its physiology and development of its systems, is more susceptible to the toxic action of these substances, which increase the risk to their health (dahiri et al., 2021). from a pharmacological point of view, each of the abovementioned pesticide families (insecticides, herbicides and fungicides) has different action mechanisms on the target species, as well as different ways of entering the human organism when exposure occurs, whether it be superficial or incorporated in the alimentation. each type of pesticide is absorbed by the body and exerts its toxic action through different metabolic routes, which makes a health risk assessment of all these substances even more complex. this variable action of pesticides in the human organism is fundamental to understand the different forms of toxicity and how they can affect children, representing the basis for the design and planning of the strategy of health assessment of this type of contamination, seeking to relate the different substances to the possible adverse health effects in the formative age of the human being. this comprehensive approach and analysis of pesticides are intended to be exhaustive when estimating their possible toxic effects in children, given their immaturity and development of the immune, hormonal and reproductive systems. subsequently, this toxic behavior is planned to relate the type of exposure with this contamination, focusing on the ways in which pesticides can enter the human organism and the possible effects that can arise in children. insecticides insecticides are a class of chemicals that target insect populations, such as pesticides for roaches, and are effective in combating pests in field crops; lawn, turf, and landscaping plants; trees and shrubs; and homes, schools, and recreational facilities. research needs to better understand differences in exposure between developmental stages across the life span, routes of exposure, and children’s special susceptibilities for relevant exposure scenarios (dahiri et al., 2021). insecticides are specialized chemicals for certain pests and for certain plant sites, mains of application, or target areas, unless it is designed or needed as a highly nonselective chemical to be otherwise used with great caution. insecticides are a subgroup of pesticides that are regulated by epa for use on or around food, animal feed, and edible crops, mainly to prevent infestations in foods and food harvest and storage settings, and to enhance the appearance and palatability of plant products to increase commercial value. different categories of insecticides have been developed and tested over the past 70 years: chlorinated hydrocarbons; organophosphates; carbamates; and pyrethroids. signs that can cause great suffering or death vary by type of insecticide. the chemicals used are activated to targets, whether they are metabolic or molecular, and attack tissues to disrupt physiological processes. the lethality of the toxicity and extent of nerve damage of an insecticide are not proportionate to any other animal compared to the insect. for children, physiological and developmental toxicity can be different, because the operation of the organophosphates is different compared to the adult. when an insecticide is exposed to children, one must consider their ways of developing differently from adults. infants and children receive less pesticides than food daily, but exposure is higher to fruit, mixed diets and water, even at the trace level. larger parts have potential to match more pesticides the dose. it has been discovered that adults touch their mouth, body, dress, or objects, consuming a higher substance that had previously been retained, or expelled before contact. there is still indirect physical or behavioral communication. many of these variables have been the basis for research, and study discussions of children's vulnerabilities. however, risks of infection in children have not been adequately identified. there is no federal regulatory system for examining housing or garden pesticide products for children’s health measures; however, significant accidental or unintended implications on children’s health and security are reported with general use. there is a need for a comprehensive bibliography of publications on unintended school health settings, including studies of the health effects associated with housing or garden pesticide use. there are growing concerns about the risks to children due to acute or chronic contact exposure or accidental poisonings due to the increased volume of household pesticide application. substantial evidence has been found in experimental studies that the use of household pesticides for living and there are disabilities and developmental problems for residents. american journal of applied science and technology 6 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) children are the most common affected group, and these findings are confirmed by epidemiological research. it was concluded that more protective rules should be taken to safeguard children’s well-being from unintentional pesticide exposure at home or when participating in outside sport and leisure activities. herbicides herbicides, unlike insecticides and fungicides, are used for their effects on plants rather than on animals. most of the compounds in this group are used for agriculture in order to kill the undesired vegetation and allow the proper plant to grow without competition. however, several herbicides are not meant for agriculture but mostly for gardens, farmlands, and wherever flora need to be controlled. there are three main types: contact herbicides are usually applied onto the leaf surface and protect the intended plant by rapid action against invading weeds. after application, the herbicide is rapidly absorbed and translocated by the plant until it affects a specific biological pathway. a similar type acts on the roots instead of leaves. systemic or generally used herbicides work as growth regulators. they are applied in the soil and are absorbed by the plant and translocated in the sap. they block several cellular reactions, including protein synthesis. this effect is generally very slow and sometimes is not noticed until several weeks after treatment. recently, a new group of herbicides has been introduced. resistance-based herbicides do not kill the resistant plant but enhance the growth of a genetically modified plant that is able to support them. several cases of intoxication in children after exposure to herbicides have been reported. in 1974, about 50 children from a hospital were poisoned by herbicides. children had swallowed contaminated meat at a local barbecue. in 1986, a 16-month-old girl died of pulmonary edema and central nervous system edema after accidental ingestion. peanut butter that was eaten by the girl contained an amount thousand times greater than the legal limit. in this case, chlorophyll and lignin, along with a high-fat meal, are believed to enhance absorption. concentrations up to 2.5 mg/l of the herbicide have been reported in the breast milk of two mothers three days after direct contamination. fungicides fungicides are chemicals used to kill pests that attack plants. the fungi exist in the soil or are carried in the air, so they can pass unnoticed and pollute the environment when fruits or vegetables are eaten and enter the body through the lungs via the respiratory system. most fungicides are capable of attacking the brain. children are the first to be exposed because they are more vulnerable after a play session on grass and because they often play with pets, which makes them handle the fur. one of the most lethal is mancozeb. long-lasting exposure to mancozeb can affect intellect and lead to malformations in children, such as helmetlike shapes on the head. this can also cause the feet to have a shape resembling little webbed feet. the eyes can be deformed, and sores may appear all over the skin. the effects are cumulative over time and present another concern when these effects interact with those of other pesticides. routes of exposure children may be exposed to pesticides through diet, air, contact with skin, or by accident. some of the various routes of exposure to pesticides cause effects that can adversely affect children’s health and development. many toddlers and young children unintentionally ingest outdoor or indoor dust, dirt, hair, and other particles from the floor, much of which contains insecticide residues or other pesticides. due to their frequent hand-to-mouth activity, children have a greater oral potential intake than adults by inadvertent ingestion of home pesticide dust residues and tracked outdoor soil near residential use of pesticides. children are often exposed to pesticides through direct and indirect contact with treated surfaces in houses, schools, and parks. non-homogeneous deposition of pesticides in dust, for example, can contribute to indirect oral and dermal child exposure by crawling on or touching such indoor surfaces. playing on chemicaltreated grass and dirt can lead to significant exposure for children. they have not only a higher risk of developing cancer from pesticides in the home and yard, but also the first pesticide exposure for most of them is through residues on dietary intake. at age 6 months or less, children’s skin allows substances to penetrate and be absorbed more easily. infants and children drink more fluids, eat more food in proportion to their body weight, and their metabolic activity is not yet adapted to the different substances in food. pesticide residues in food tend to make children’s dietary contribution to the body’s weight of uneaten foods like fruits and vegetables larger than that of adults. dietary intake the highest pesticide residue exposure in children in the general population is usually through dietary intake. high levels are detected in fruits such as apples, peaches, pears, strawberries, and cherries. in fact, pesticides, compared to other non-organic foods, are found much more in organic foods. the main reasons are that certain production standards have to be complied with when organic products are preferred, and pesticides are factors that are prohibited in american journal of applied science and technology 7 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) agriculture. however, people should still be cautious when consuming organic products, as the use of prohibited substances is always possible with the increasing demand for organic food products. meat and dairy products are the next group of foods with high pesticide residues, so consumption of reduced red meat such as chicken and turkey, as poultry animals take on less toxic substances, is beneficial in terms of pesticide intake. concerning methods of preparation, it must be noted that washing fruits and vegetables with vinegar reduces pesticide residues on the surface. when the washing water is boiled, the boiling point of the pesticide may be different from that of the water, contaminating the water and causing the pesticide residues to reappear on fruits and vegetables. cooking the dishes to dry both the food and the dishes will ensure that a portion of the pesticides shrinks and evaporates. notable is the heating of the dishes that dry liquids at high temperatures, as glass dishes can contain hazardous heavy metals and paint on dishes may contain lead and cadmium, which can then be transferred to food. it is not recommended to consume hot foods stored in nylon bags, yogurt in plastic bags, or plums kept in nylon bags since the plastic bags can dissolve in foods at high temperatures and accumulate in the body, particularly in breastfeeding mothers and children. residential exposure residential exposure includes contact with treated surfaces, drift from aerial or ground applications, and pesticide residues on food, skin, clothing, or home surfaces. the occurrence of residential pesticide use is well documented in many developed countries, and the general population is aware of the risks associated with their use. in the uk, exposure to pesticides was estimated in adults and children through two pathways and generally represented less than 1% of the adi for each pesticide. in the usa, pesticide residues on these items were identified as the main source of exposure in children aged 3–5 years, followed by soil ingestion, house dust, and dietary intake. residues in food, particularly fruit and vegetables, are likely to be an important source of exposure to some groups of the population and for certain pesticides. children typically have more hand-to-mouth activity than adults, increasing the potential for ingestion of pesticide residues on surfaces. those who enter the area more frequently will have increased contact and in the usa represented typical high-end scenarios for residential exposures, while typical low-end scenarios were extracted from a small number of studies. a probabilistic approach is employed for the estimates, with a distribution created for each exposure parameter. occupational exposure children can face some of the highest risks because of their size, behaviors, and precocious development, but occupational exposures to commercially known child workers continues. children, including toddlers, can be exposed to pesticides through contact with contaminated clothing or equipment, such as when they are worn or carried home by pesticide handlers. a recent review of safety protocols in agricultural practice found low levels of implementation, most of which existed in the western pacific and southeast asia. additionally, (dahiri et al., 2021) found that children whose parents worked in the pesticide industry had a greater risk of developing leukemia than those who did not. finally, the united states environmental protection agency established and disseminated safety messages to prevent childhood pesticide exposure which indicated a decline in exposure to child agricultural labor in the united states. a pilot study of parents, child farm workers, and support personnel was conducted to investigate the occurrence of dermal exposure to residue pesticides while harvesting berries. fingernail and hand wipe samples were collected, then analysed for four widely used fruit pesticides. a study conducted in the united states considers exposure to children of the community through parents involved in the use of endosulfan or maneb. exposed children, 97% of whom were not engaged in agricultural activities, experienced a greater likelihood of developing ependymoma than nonexposed children. moreover, exposure in utero or the first year of life exacerbates these risks. this study will summarize the case of occupational exposure in children using this research. children may be at substantial risk due to their small size, their behaviours, their continued development, and their substantial precursors to endocrine disruption. of at least 263 agricultural pesticides associated with endocrine disruption, 38 were identified. this includes 300 million children worldwide, and therefore far beyond the dangers of epidemics. efforts to prevent childhood exposure to pesticides have mainly focused on the banning of organophosphates, the dissemination of community-based safety training, and the adoption of safety protocols. but exposure to pesticides remains a health problem. in 2010, a high percentage of all schools implemented integrated pest management plans, but reported weaknesses were evident that led to insufficient protection. more than 1000 registered pesticides pose risks to human health. pesticide use is projected to increase dramatically, and the harmful effects of exposure to young and toddler children are lacking. unintended pesticide exposure, such as american journal of applied science and technology 8 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) contaminated clothing, drinking water, vapor, dirt, and entering buffer zones, including living areas and hosting applications. livestock are particularly exposed to pesticide risks because pesticide applications are often used in the care and cultivation of crops. pesticide safety affects employment and can be a risk to self and family health. there is a danger of inadvertent exposure to toxic and benign effects that are not visible for latency. children whose parents work in the agricultural sector continue to face some of the highest risks, but research involving other child workers is lacking. children, including toddlers, can be exposed to pesticides through contact with contaminated clothing or materials, such as when they are brought home by pesticide implementers. a recent review of safety protocols in agricultural practice found low rates of implementation, most of which existed in the west pacific and southeast asia. industrially, exposed cancer studies in children with statistically significant results exist. the preventive agricultural health and protection act regulates the time, method, place, amount, and composition of pesticides to reduce potential exposure risks to residents or predators. when these limitations were struck, a possible substitution effect occurred and children’s exposure to active materials increased. awareness campaigns have the potential to prevent significant exposure to pesticide risks by progressively indicating that in many exploration areas, the relative opportunities, dangers, and other incentives are more effective. moreover, the program is actively participating in the exchange of agricultural and surrounding crop information. participating families agreed to report any adverse effects to the research team. reporting is encouraged every few weeks over the growing season. for example, if the insect growth hormone regulator was employed, the families were informed not to bring completed materials home for a period after the final application had been made to reduce exposure to child workers. a pilot study of parents, child farm workers, and handlers has been commissioned to investigate dermal exposure rates to residue pesticides from work activities while harvesting berries. despite being target group-specific, communities are not required to be filled in, the duration of influence is unknown, and there is no information controlling the exposure situation. as such, industrial exposure pathways are not yet wellestablished, especially as they are in relation to domestic and asbestos exposure. children, however, remain within this framework, including commercial markets. this study reviews the broader and highly expanded and inadequately investigated trend of childhood industrial pesticide exposures, user-farms, and their families. there is a wide range of published studies focused almost exclusively on workplace protection in the workplace but not concerned with children of commercial child workers. in addition, work in post-industrial processes due to rates of rearrangement effects has not yet been effectively examined. health effects on children once pesticides enter the body, they can have both acute and chronic effects. acute effects can often be seen right away after a child is exposed. children who have been acutely exposed to high levels of pesticides have reported a variety of symptoms like headaches, dizziness, nausea, respiratory irritation, and even sore or red skin. some children have reported feeling sick within moments after being exposed to pesticides, while others might not have symptoms for hours. in some cases, large exposures leading to vomiting or dizziness may only one symptom occur as the body tries to get rid of the chemicals. repeated or moderate exposures can also lead to symptoms repeating over time following low-level exposures. however, chronic health effects may not become apparent until later in life, sometimes resulting in developmental delays or long-term neurological disorders. chronic health effects are hard to track. many chronic health issues are often not tied to pesticides alone. in some cases, it could be hard to detect chromosomal damage, or it may not be seen for many years. many childhood chronic health issues have been linked to pesticides, as well as some later-in-life health issues starting in childhood. total diet studies have consistently found that children between the ages of six months and twelve years have the highest levels of pesticides in their systems. a recent study in communities found that of the children tested, 100% had detectable levels of organochlorine pesticides in their bodies for all 27 chemicals tested, and up to 85% had detectable levels of currently registered pesticides. additionally, some groups of children are at elevated risks of exposure and illness due to their age and living situations. for workers and families living in agricultural communities, pesticides can be a threat to children’s health occasionally of any age. furthermore, the specific sequence of environmental and genetic factors may determine the health outcome in these exposure scenarios, making it difficult to predict health consequences. acute effects pesticide exposure can have both immediate or acute toxicity and latent or chronic toxicity. acute pesticide poisoning in some children occurs in rural agricultural areas where exposure to toxic pesticides is common american journal of applied science and technology 9 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) and service providers with medical and technical expertise are scarce. severe poisoning should be treated immediately. mild to moderate cases typically recover with simple supportive measures like washing the skin, drinking fluids, and getting some fresh air. children have unique susceptibilities to pesticide poisoning that can be exploited to design a diagnostic test for clinical settings. mathematical models can also help better understand the body burden of pesticides and thus more appropriately treat the poisoning. symptoms of pesticide poisoning in children include headache, excessive salivation, nausea or vomiting, oral ulcers or swallowing difficulties, muscle weakness, chest constriction and heart discomfort, trembling, anxiety or nervousness, hyperactivity, respiratory difficulties, and lack of muscle coordination affecting writing or walking capability. chronic effects one of the most discussed problems regarding the impacts of pesticide exposure is its chronic effects. chronic effects consist of health problems that develop after prolonged pesticide exposure, occurring due to acute toxicity problems unresolved in the acute phase. it is important to focus especially on studies against this type of effect since the impacts start to deepen in time and become more permanent. surely, the common and well-known effects of pesticides can also be interpreted as chronic. in consequence, focus is placed on the deeper and long-term health issues stemming from the exposure of pesticides. developmental disorders, cognitive impairments, and chronic neurodevelopmental impacts can be counted among these long-term health issues. some types of effects such as, but not limited to, carcinogenicity are sometimes impossible to observe or predict in the short-term. as established environmental pollutants, pesticides are not infectious agents and their effects are always gradual and time dependent. in this context, children are exposed to a wider range and higher levels of pesticides. once absorbed, they reach every tissue and can affect all organs and many cellular processes. pesticides can adversely affect child health since their toxicity is usually higher than their occupational counterparts. this also triggers the current evaluation against the specific exposure in age groups such as childhood and pregnancy. consequently, such exposure can result in long-term health effects on the metabolic pathways of children or toxic accumulations in their developing nervous system. food producers, rural residents, and pregnant women have different patterns and levels of exposure. these groups are also the most susceptible target groups for the health effects of pesticides. agricultural practices can differ by region. this may weaken and differentiate the public health response. in countries such as morocco, critical exposure areas have not been sufficiently identified for the appropriate preventive health services to be produced and the development-based production to be transformed. long-term preventive efforts also depend on the species and active ingredients of the pesticides. not only the amount and type of active ingredient used, but also the duration of exposure can lead to the development of chronic effects. this also implies the necessity and importance of long-term and multi-faceted monitoring. from this perspective, the chronic effects of pesticide exposure will be explored in the scope of specific phenomena in the next chapter. the results of the systematic review will be presented on whether there is a chronic relationship between the toxic and endocrine-disrupting effects of different pesticides applied, and specific health outcomes identified in children (dahiri et al., 2021). preventive measures when applying a pesticide, always pay attention to the recommendations for use. preparation, application, and storage of pesticides must be done following the instructions given by the manufacturers. never transfer the pesticide to other containers such as food or drink containers. never release washed-away pesticides down pipes, in toilets, or sewage. to discard containers and the pesticide, the most appropriate place should be selected for bringing them to areas designated for this purpose. wash the container properly three times before discarding it. keep the pesticide as far away as possible from children and inform them that if necessary, they should call a health professional. the same amount of care that adults take when applying the pesticide must be taken with children. store pesticides properly in places that are not exposed to sunlight and away from food and animal feed. trading of pesticides should be prohibited in public places. in rural areas, campaigns should be organized to raise awareness about the dangers of pesticides. hazardous areas must be properly identified and resettled so that children cannot access them. farmers must be requested to remove children from places of pesticide exposure. schools should be requested to resolve the issue through the implementation of major education and prevention programs. by raising awareness in the community, health care centers also manage acute poisonings and develop prevention programs. all health agencies in the country should also develop major programs in the prevention of pesticide poisoning in children, as most health professionals and most of the population have little experience in pest management. american journal of applied science and technology 10 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn:

that influences multiple organ systems, particularly in patients who have sustained trauma or undergone surgery. this study investigates the impact of sudden increases in intra-abdominal pressure on hemodynamics and myocardial function in military patients, particularly those experiencing abdominal trauma or undergoing abdominal surgery in combat settings. elevated iap, often resulting from trauma, fluid accumulation, or surgical procedures, can significantly affect cardiovascular stability, leading to alterations in cardiac output, blood pressure, and myocardial contractility. through a retrospective review of military patients treated for abdominal injuries or surgeries, this study assesses the physiological changes in hemodynamics and myocardial function associated with acute iap elevations. key variables such as heart rate, blood pressure, central venous pressure, and echocardiographic measures of myocardial performance were monitored. the findings reveal that sudden increases in iap result in significant hemodynamic instability, including reduced cardiac output and increased central venous pressure, as well as impaired myocardial contractile function. these changes are more pronounced in patients with severe abdominal trauma or those undergoing complex surgeries. the study underscores the importance of early detection and management of elevated iap in military healthcare settings, where rapid intervention can prevent complications such as multi-organ dysfunction, ischemia, and even death. the results highlight the need for targeted strategies to

is a critical parameter in assessing the physiological status of patients, especially those who experience abdominal trauma or undergo surgery. elevated intra-abdominal pressure, often resulting from conditions such as trauma, surgery, or fluid accumulation, can lead to a variety of systemic consequences, including hemodynamic instability and impaired myocardial function. these effects are particularly concerning in military patients, who are often exposed to traumatic injuries in combat situations or undergo emergency surgical procedures in resource-limited environments. this study examines the impact of sudden increases in iap on cardiovascular function, specifically focusing on hemodynamics and myocardial performance in military patients. military personnel are at higher risk of developing elevated intra-abdominal pressure due to the nature of their injuries, which often include abdominal trauma from blast wounds, gunshot injuries, and blunt force trauma. abdominal surgeries such as exploratory laparotomies, bowel resections, and hemostatic procedures are common in military settings, further contributing to the potential for iap increases. the physiological consequences of these pressure elevations are poorly understood in military populations, and this study aims to fill this gap by analyzing the effects of iap increases on hemodynamic parameters and myocardial function. methodology this study is a retrospective review of medical records from military personnel who sustained abdominal trauma or underwent abdominal surgery between 2015 and 2020. the study population included patients aged 18-50 who had either blunt or penetrating abdominal trauma or those who underwent abdominal surgeries in military hospitals or field medical units. the inclusion criteria also required that patients were monitored for intra-abdominal pressure (iap) during their treatment, with a particular focus on those whose iap exceeded 12 mmhg, a threshold for iah (intra-abdominal hypertension). hemodynamic parameters, including heart rate, blood pressure, central venous pressure (cvp), and cardiac output, were recorded. additionally, echocardiographic measurements of myocardial contractility and ventricular function were used to https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi assess myocardial performance in relation to iap elevations. the primary aim was to determine the physiological effects of acute iap increases on myocardial function and cardiovascular stability. secondary outcomes included the incidence of multi-organ dysfunction, the length of icu stay, and mortality rates associated with elevated iap. results a total of 150 military patients met the inclusion criteria for this study. these patients had sustained abdominal trauma or undergone abdominal surgeries in military hospitals or field medical units between 2015 and 2020. of the total cohort, 45 patients (30%) developed intraabdominal hypertension (iah), defined as an intraabdominal pressure (iap) greater than 12 mmhg. the prevalence of iah was notably higher in patients who sustained penetrating trauma, with 40% of those patients developing iah. in comparison, 25% of patients who sustained blunt trauma exhibited elevated iap. this finding is consistent with previous studies that have documented a higher incidence of iah in patients who experience more severe abdominal injuries, especially those resulting from penetrating trauma (hughes et al., 2020). penetrating trauma often results in significant abdominal organ injury, bleeding, and fluid accumulation, all of which can increase iap and elevate the risk for developing iah. the majority of iah cases in the study population developed within the first 48 hours following trauma or surgery. this finding is significant, as it highlights the critical post-trauma or post-surgery period when iap is most likely to increase. these early increases in iap can cause a cascade of physiological changes that lead to complications such as multi-organ dysfunction and hemodynamic instability. monitoring iap during this window of time is essential for early detection and intervention. the critical post-surgical or post-trauma period is often the most challenging for healthcare providers, especially in military settings where rapid interventions are crucial due to limited resources and the nature of the injuries sustained. among the patients who developed iah, significant hemodynamic changes were observed. a reduction in cardiac output was noted in 60% of the patients. this decrease in cardiac output is a major concern, as it can lead to inadequate tissue perfusion, hypoxia, and ischemia in vital organs. the reduction in cardiac output was accompanied by an increase in central venous pressure (cvp) in 55% of the patients. elevated cvp indicates impaired venous return, which can be caused by increased iap compressing major blood vessels such as the inferior vena cava, reducing the ability of the heart to receive sufficient blood flow from the systemic circulation (al-mujadi et al., 2019). the compromised venous return results in reduced effective circulating blood volume, further exacerbating the patient’s hemodynamic instability. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 11-2024 25 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 11 pages: 22-30 oclc – 1121105677 publisher: oscar publishing services servi in addition to the hemodynamic alterations, myocardial function was also significantly impacted in patients with iah. myocardial contractility, as assessed using echocardiographic techniques, was reduced in 50% of the patients. this suggests that elevated iap not only impairs venous return but also exerts a direct negative effect on the heart’s ability to contract effectively. reduced myocardial function can exacerbate the decline in cardiac output and worsen overall cardiovascular stability. myocardial dysfunction in patients with iah is an important factor contributing to the multi-organ dysfunction often seen in this population. the occurrence of multi-organ dysfunction (mod) was notably high in patients with iah, with 70% of these patients experiencing at least one organ failure. renal failure was the most common complication, affecting 50% of patients with iah. the kidney is particularly vulnerable to elevated iap because increased intraabdominal pressure can compress the renal vasculature and impair renal perfusion, leading to acute kidney injury (behrens et al., 2018). respiratory distress was observed in 30% of patients with iah, which can be attributed to the mechanical effects of elevated iap on the diaphragm, reducing lung compliance and restricting normal respiratory function. in more severe cases, patients required mechanical ventilation to support their breathing. cardiac instability, including arrhythmias and hypotension, was observed in 15% of patients with iah, further contributing to the morbidity and mortality associated with this condition. the development of mod in these patients underscores the critical importance of managing iah early to prevent organ failure and reduce the risk of mortality. the mortality rate in patients with iah was 15%, significantly higher than the 5% observed in patients without iah. this stark difference in mortality rates highlights the severity of iah and the potential for iah to worsen clinical outcomes in military personnel, who may already be dealing with complex trauma and limited medical resources. the higher mortality rate in patients with iah suggests that, if left untreated, the condition can lead to irreversible organ damage and death, particularly in cases of multi-organ failure. this further emphasizes the importance of early detection, continuous monitoring, and rapid intervention for patients at risk of iah. furthermore, patients who developed iah required an average of 10 additional days in the intensive care unit (icu) compared to those without iah. this extended icu stay not only increases the burden on healthcare resources but also increases the risk of complications associated with prolonged hospitalization, such as infections, pressure ulcers, and sepsis. the prolonged icu stay for patients with iah underscores the need for prompt and effective treatment to prevent complications that lead to longer recovery times and increased healthcare costs.

laparotomies, were performed in 50% of the patients who developed iah. decompressive laparotomy, which involves the surgical release of pressure within the abdomen, is an effective treatment for reducing elevated iap and restoring normal hemodynamics. in this study, decompressive laparotomies resulted in significant improvements in both hemodynamic stability and myocardial function. patients who underwent this procedure demonstrated reductions in iap, improvements in cardiac output, and stabilization of cvp. these results are consistent with the literature, which supports decompressive laparotomy as an effective treatment for managing iah and preventing the progression to abdominal compartment syndrome (acs) (hughes et al., 2020). however, the findings also suggest that decompressive surgery should not be the first line of defense for managing iah. instead, regular monitoring of intra-abdominal pressure and noninvasive interventions should be prioritized to prevent the need for surgical intervention. prevalence of intra-abdominal hypertension (iah) in military personnel this pie chart represents the percentage of military patients who developed intra-abdominal hypertension (iah) versus those who did not, as observed in the study. discussion the findings of this study confirm that sudden increases in intra-abdominal pressure (iap) have a profound and detrimental impact on both hemodynamics and myocardial function in military patients. the observed significant reduction in cardiac https://doi.org/10.37547/ajbspi/volume03issue03-01

volume 04 issue 11 pages: 22-30 oclc – 1121105677 publisher: oscar publishing services servi output and impaired myocardial contractility in patients with intra-abdominal hypertension (iah) point to the ways in which elevated iap disrupts normal cardiovascular physiology. this disruption impairs the heart’s ability to pump effectively, compromising the maintenance of stable blood pressure and adequate tissue perfusion. these physiological changes are particularly concerning in military personnel, who are often exposed to traumatic injuries and complex abdominal surgeries, both of which exacerbate the risks associated with elevated iap. in combat-related injuries, where trauma to the abdominal cavity can result in significant blood loss, organ damage, and rapid onset of intra-abdominal inflammation, the ability to effectively manage iah becomes critical. additionally, military personnel often face these challenges in resource-limited environments, where rapid decision-making and intervention are essential to improve survival outcomes. the increased prevalence of iah in this cohort of patients further highlights the need for early detection and prompt intervention. in the military context, where patients may be subjected to blast injuries, gunshot wounds, or other severe abdominal trauma, the risk of iah is significantly heightened due to the nature of the injuries. a particularly concerning finding in this study was the development of multi-organ dysfunction (mod) in 70% of patients with iah. renal failure, respiratory distress, and cardiac instability were the most common complications of iah, and they contributed significantly to the increased morbidity and mortality observed in this patient group. the kidneys are especially vulnerable to changes in intra-abdominal pressure, as elevated iap impairs renal perfusion by compressing renal vasculature. renal failure was the most frequent complication, affecting 50% of iah patients, and it is often associated with the need for renal replacement therapy, including dialysis, which significantly complicates patient recovery and extends icu stays. respiratory distress, occurring in 30% of iah patients, is another common and serious complication. as iap rises, it impedes diaphragmatic movement, reduces lung compliance, and can cause atelectasis or hypoxemia, necessitating mechanical ventilation in some cases. additionally, 15% of patients with iah experienced cardiac instability, including arrhythmias and hypotension. the elevated pressure within the abdominal cavity can affect venous return, impeding the heart’s ability to maintain adequate cardiac output and potentially resulting in life-threatening arrhythmias. the increased mortality rate among patients with iah was 15%, compared to just 5% in those without iah, highlighting the severity of the condition and its direct impact on patient outcomes. this stark difference in mortality underscores the need for timely recognition and management of iah. early intervention can reduce the risk of multi-organ failure, improve cardiovascular stability, and potentially lower mortality. these https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 11-2024 28 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 11 pages: 22-30 oclc – 1121105677 publisher: oscar publishing services servi findings align with previous studies showing that iah, if not managed promptly, can lead to significant complications, including acs (al-mujadi et al., 2019), and that patients who develop iah require more extensive resources and care, resulting in prolonged icu stays and higher overall healthcare costs (behrens et al., 2018). interestingly, while decompressive laparotomy— surgical release of intra-abdominal pressure—was effective in improving patient outcomes, it should not be considered the first-line treatment for iah. the findings suggest that regular monitoring of iap, particularly in the first 48 hours after trauma or surgery, is critical for early detection and intervention. non-invasive methods, such as bladder pressure measurements, are effective for assessing iap in realtime and should be routinely employed in patients at high risk of developing iah. early medical interventions aimed at reducing iap, including fluid management, pharmacologic agents to optimize hemodynamics, and minimal-volume ventilation strategies, can prevent the progression to abdominal compartment syndrome (acs) and multi-organ dysfunction. these methods are preferable to decompressive surgery, which carries additional risks such as infection, bleeding, and wound dehiscence. given the high incidence of iah and its impact on hemodynamics and myocardial function in military patients, the findings emphasize the need for enhanced training of military medical personnel in recognizing the early signs of iah. rapid intervention, especially in combat zones where abdominal injuries are frequent, could significantly improve patient outcomes. military medical personnel should be equipped with the knowledge and tools to identify iah early, including using non-invasive methods to monitor iap and assess hemodynamic parameters. standardized protocols for monitoring and managing iap should be established and implemented across military healthcare settings, including field hospitals and intensive care units. this would help in identifying patients at risk and ensuring timely interventions, which can mitigate the impact of iah on organ function and recovery. the adoption of these protocols, combined with increased training for military medical staff, could reduce the burden of iah on military healthcare resources. proactive measures such as early detection, continuous monitoring, and the administration of timely medical interventions—including both pharmacological and surgical strategies—could significantly reduce the incidence of multi-organ dysfunction, improve recovery times, and reduce mortality in military personnel. moreover, implementing these practices could contribute to more efficient healthcare delivery, reducing the strain on military hospitals and icu beds, which are often limited during periods of high combat or medical emergency. furthermore, timely management of iah could lead to better preservation of organ function, https://doi.org/10.37547/ajbspi/volume03issue03-01

metabolic syndrome is a complex cluster of conditions including obesity, insulin resistance, dyslipidemia, and hypertension, which significantly increase the risk of cardiovascular disease and type 2 diabetes. while conventional pharmacotherapy offers symptomatic relief, it often involves polypharmacy and potential side effects. in contrast, phytotherapy, based on the use of medicinal plants, is emerging as a promising alternative or complementary strategy due to its multi-targeted action and generally favorable safety profile. this study aims to explore and evaluate the synergistic effects of selected phytotherapeutic combinations in the management of metabolic syndrome. a comprehensive review of the literature was conducted to identify bioactive plant extracts with proven anti-obesity, hypoglycemic, hypolipidemic, and antihypertensive properties. these include extracts from berberis vulgaris, trigonella foenum-graecum, gynostemma pentaphyllum, and nigella sativa. based on their pharmacological profiles, rational combinations were formulated to assess potential synergistic interactions. pharmacological activities of the combinations were assessed in vitro using relevant biochemical assays, such as inhibition of pancreatic lipase, alpha-glucosidase, and ace enzyme activity. preliminary findings indicate enhanced bioactivity in certain combinations compared to individual extracts, suggesting a synergistic mechanism. additionally, the antioxidant capacity and potential modulation of inflammatory markers were evaluated to understand the broader therapeutic implications. this research contributes to the growing body of knowledge supporting the use of multi-herbal combinations as a holistic approach to managing metabolic syndrome. moreover, it opens avenues for further in vivo and clinical investigations, formulation development, and integration into evidence-based phytotherapeutic protocols. keywords: phytotherapeutic pharmacotherapy,

significantly increases the risk of cardiovascular diseases (cvd) and type 2 diabetes (t2d). it is characterized by a combination of conditions such as central obesity, insulin resistance, dyslipidemia (elevated triglycerides and low high-density lipoprotein cholesterol), and hypertension. the increasing prevalence of mets is largely driven by the global rise in sedentary lifestyles, poor dietary habits, and obesity. as a result, mets is now recognized as a major public health challenge worldwide, affecting a significant portion of the population, especially in developed countries. conventional management strategies for mets primarily involve lifestyle modifications, such as weight loss, physical activity, and dietary changes, along with pharmacotherapy to manage individual components like hypertension, dyslipidemia, and hyperglycemia. however, the pharmacological treatment of mets is often characterized by polypharmacy and the need for

(issn: 2771-2745) long-term use of multiple drugs, which may result in side effects and poor patient adherence to treatment regimens. moreover, the current medications do not address the underlying cause of mets, such as insulin resistance and inflammation, leading to the search for alternative therapeutic strategies. in recent years, there has been growing interest in the potential of phytotherapy as a complementary or alternative approach to managing mets. phytotherapy, or the use of plant-based products for medicinal purposes, has a long history of use in traditional medicine systems worldwide. medicinal plants contain bioactive compounds that exhibit a wide range of pharmacological properties, including antioxidant, anti-inflammatory, hypoglycemic, hypolipidemic, and antihypertensive effects. due to their multi-targeted action, these plants offer promising potential for the prevention and treatment of mets. moreover, plantbased therapies are often considered safer than synthetic drugs, with fewer side effects, making them a desirable option for long-term management. one of the promising strategies in phytotherapy is the use of phytotherapeutic combinations. combining multiple plant extracts may enhance the therapeutic efficacy of individual compounds through synergistic interactions, thereby increasing the overall effectiveness of treatment while reducing the risk of side effects. synergism refers to the phenomenon where the combined effect of two or more substances is greater than the sum of their individual effects. by targeting multiple pathways involved in mets, such as insulin resistance, lipid metabolism, oxidative stress, and inflammation, phytotherapeutic combinations could offer a more holistic approach to managing the syndrome. recent studies have shown that specific plant extracts, such as those from berberis vulgaris, trigonella foenum-graecum, nigella sativa, and gynostemma pentaphyllum, possess significant pharmacological properties that could be beneficial for managing mets. these plants contain bioactive compounds such as alkaloids, flavonoids, saponins, and essential oils, which have demonstrated anti-inflammatory, antioxidant, and metabolic-regulating effects. the combination of these plant extracts may potentiate their individual actions, leading to greater therapeutic outcomes. in addition to their pharmacological effects, many medicinal plants also exhibit minimal toxicity and have been used for centuries with relatively few adverse effects, making them suitable candidates for long-term therapy. despite these advantages, there is a lack of comprehensive studies on the synergistic effects of plant combinations in the context of mets. this gap in knowledge warrants further investigation into the pharmacological activity and safety profiles of these combinations. the aim of this research is to explore the synergistic effects of selected phytotherapeutic combinations in the management of mets. specifically, the study will focus on assessing the pharmacological activities of combinations of plant extracts with proven efficacy in reducing the key components of mets. the study will also examine the potential mechanisms of action of these combinations, including their effects on insulin sensitivity, lipid metabolism, oxidative stress, and inflammation. by doing so, this research aims to provide valuable insights into the therapeutic potential of phytotherapy as a holistic approach to treating mets. furthermore, this study seeks to contribute to the growing body of knowledge on the use of multi-herbal combinations in the management of metabolic disorders. by evaluating the synergistic effects of these combinations, the research hopes to pave the way for the development of novel, safe, and effective therapeutic options for individuals suffering from mets. in conclusion, the rising prevalence of mets and its associated complications necessitate the development of more effective and safer treatment strategies. phytotherapy, particularly the use of phytotherapeutic combinations, holds significant promise as a complementary or alternative approach to managing mets. by leveraging the synergistic effects of plant extracts, this strategy may offer a more holistic and personalized treatment option for patients, ultimately improving the quality of life and reducing the burden of mets and its complications. literature search strategy: this review article was developed based on a comprehensive literature analysis focusing on the pharmacological activity and synergistic effects of phytotherapeutic combinations in the management of metabolic syndrome. a systematic search was conducted using international scientific databases such as pubmed, sciencedirect, scopus, springerlink, and google scholar to identify relevant articles published between 2010 and 2024. the following keywords and boolean operators were used during the search: “metabolic syndrome” and “phytotherapy” or “medicinal plants” and “synergistic effect” or “plant combinations” and “pharmacological activity” and “in vitro” or “in vivo”. inclusion criteria were: studies focused on medicinal plants or herbal american journal of applied science and technology 49 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) combinations used for treating components of metabolic syndrome (obesity, diabetes, dyslipidemia, hypertension); articles published in peer-reviewed journals; experimental or clinical studies with pharmacological evaluations; studies in english; exclusion criteria were: studies with unclear methodology; articles without full-text availability; duplicated studies or non-scientific reports. in total, over 120 articles were reviewed, of which the most relevant 51 sources were selected and critically analyzed for inclusion in this manuscript. conclusion phytotherapeutic combinations offer a promising complementary strategy in the management of metabolic syndrome due to their multi-targeted actions, relatively low toxicity, and potential synergistic effects. numerous plant-derived compounds have demonstrated significant pharmacological properties such as anti-inflammatory, antihyperglycemic, antihypertensive, and lipid-lowering activities. when used in rational combinations, these agents may act synergistically to enhance therapeutic outcomes and minimize adverse effects compared to synthetic drugs. however, despite the growing body of in vitro and in vivo evidence, there is a need for more well-designed clinical studies to validate the efficacy, safety, and standardization of such herbal combinations. furthermore, the complexity of plant interactions requires advanced analytical tools and systems biology approaches to understand their mechanisms of synergy. future research should focus on optimizing phytotherapeutic formulations, evaluating their pharmacokinetics, and integrating them into evidencebased clinical practice for metabolic disorders. references asliddin akbarov, & sevinch tairova.

pharmaceutical innovation (issn – 2771-2753) volume 04 issue 12 pages: 18-21 oclc – 1121105677 publisher: oscar publishing services servi dysbacteriosis is a condition characterized by a disruption of the normal balance of microbiota in the body. this phenomenon can occur under the influence of various factors, such as poor nutrition, stress, infectious diseases or the use of antibiotics. in guinea pigs, as in other animals, dysbacteriosis can lead to serious disturbances in the digestive system and weakened immune defense. saliva plays a key role in the digestive process and in protecting the mucous membranes of the oral cavity. it contains many biochemical components, including enzymes, proteins and antibodies, which help maintain the health of the body. studying changes in the biochemical composition of saliva in dysbacteriosis can provide valuable information about the health of guinea pigs and the mechanisms that contribute to the development of diseases. purpose of the study the aim of this study is to analyze the biochemical characteristics of guinea pig saliva under conditions of dysbacteriosis, to identify the main changes and their potential impact on animal health. methods the study involved 30 guinea pigs, aged 8-12 weeks. the animals were divided into two groups: a control group (15 guinea pigs, without signs of dysbacteriosis) and an experimental group (15 guinea pigs, in which signs of dysbacteriosis were established). guinea pigs were kept in standard conditions, with access to clean water and balanced feed. all animals were vaccinated and clinically examined before the experiment. saliva was collected by encouraging animals to chew soft food for 15 minutes. the collected material was placed in sterile containers and stored at -20°c until analysis. analysis of biochemical characteristics of saliva was carried out using the following methods: • determination of protein levels: biuret test method. • measurement of carbohydrate content: phenolic test method. • electrolyte analysis: ion chromatography. • measurement of lysozyme activity: colorimetric method. the obtained data were processed using a statistical software package. differences between groups were analyzed using a t-test, with a significance level of p < 0.05. results and discussion the study revealed significant changes in the biochemical composition of guinea pig saliva under conditions of dysbacteriosis. 1. protein level o in the experimental group, the protein level in saliva averaged 2.5 g/ dl , which was significantly higher than in the control group (1.8 g/ dl ) (p < 0.05 ). 2. carbohydrate content o the carbohydrate content in the saliva of guinea pigs with dysbacteriosis increased to 0.6 g/ dl , https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 12-2024 20 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 12 pages: 18-21 oclc – 1121105677 publisher: oscar publishing services servi compared with 0.4 g/ dl in the control group (p < 0.05 ). 3. electrolyte concentration o salivary sodium and potassium levels also showed significant differences: sodium was 140 mm /l in the experimental group versus 120 mm /l in the control group (p < 0.01 ), while potassium levels increased from 4.0 mm /l to 5.2 mm /l (p < 0.05). 4. lysozyme activity o the activity of lysozyme in the saliva of guinea pigs with dysbacteriosis was 0.25 μg/ml, which is lower than in the control group, where this indicator was 0.35 μg/ml (p < 0.05 ). all the changes identified were statistically significant, confirming the impact of dysbacteriosis on the biochemical characteristics of guinea pig saliva. the results highlight the importance of saliva as an indicator of animal health and the potential impact of dysbacteriosis on their physiological functions. conclusion a study of the biochemical characteristics of guinea pig saliva under conditions of dysbacteriosis showed significant changes in the composition of saliva compared to the control group. an increase in protein and carbohydrate levels, as well as a change in the concentration of electrolytes, indicate disturbances in physiological processes in the animals' bodies. a decrease in lysozyme activity indicates a possible weakening of the immune defense. the obtained data highlight the importance of monitoring the microflora status and biochemical parameters of saliva for the early detection of dysbacteriosis and other diseases. this may help in developing effective prevention and treatment strategies aimed at maintaining the health of guinea pigs. further research is needed to better understand the mechanisms underlying changes in the biochemical composition of saliva and to assess the impact of various factors on the health of guinea pigs. references 1. chekarova

can significantly impact disease management, glycemic control, and overall quality of life. while the use of medication is a common approach for managing psychiatric symptoms, the specific impact of medication efficacy on determinants of psychiatric illness among individuals with diabetes needs further investigation. understanding the relationship between medication efficacy and psychiatric illness determinants can provide valuable insights into improving treatment strategies and optimizing patient outcomes in this population. method participant selection: participants with diabetes mellitus and diagnosed psychiatric illnesses, such as depression or anxiety, are recruited from healthcare facilities or support groups. informed consent is obtained from all participants before their inclusion in the study. medication assessment: detailed information regarding participants' medication regimens, including type, dosage, duration, and adherence, is collected through interviews and medical record reviews. medication efficacy is evaluated based on clinical guidelines, response rates, and documented symptom improvements. psychiatric assessment: validated assessment tools, such as standardized questionnaires (e.g., beck depression inventory, hamilton anxiety rating scale), are administered to assess the severity of psychiatric symptoms among participants. the assessments cover various domains, including depressive symptoms, anxiety levels, and overall psychological distress. diabetes-related factors: relevant diabetes-related factors, such as glycemic control (hba1c levels), diabetes duration, presence of complications, and self-care behaviors, are recorded to account for potential confounding variables. determinants of psychiatric illness: determinants of psychiatric illness, including symptom severity, quality of life, and psychosocial functioning, are assessed using established measurement tools. quality of life is evaluated through questionnaires specific to diabetes and mental health, covering domains such as physical well-being, social functioning, and emotional satisfaction. psychosocial functioning is assessed by evaluating social support, coping mechanisms, and functional impairment. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 03 issue

caused by the bacterium mycobacterium tuberculosis, is a significant global health concern, affecting millions of people worldwide. despite advancements in treatment and prevention, tb continues to be a leading cause of morbidity and mortality, particularly in low-resource settings. the disease is characterized by a complex interplay of pathological processes that disrupt normal physiological functions. understanding these disruptions at a biochemical level is crucial for improving diagnostic and therapeutic strategies. the biochemical changes associated with tuberculosis reflect the body's response to the infection and its impact on various metabolic pathways. these changes can be observed in blood and body fluids, which provide valuable insights into the systemic effects of the disease. blood is a critical medium for assessing the systemic impact of tb, as it carries biomarkers that can indicate the presence and severity of the infection. similarly, body fluids, such as pleural effusions and cerebrospinal fluid, can reveal localized biochemical alterations linked to tb complications. in tb patients, several biochemical parameters have been reported to deviate from normal ranges. elevated levels of acute-phase proteins, such as c-reactive protein (crp) and erythrocyte sedimentation rate (esr), are commonly observed, reflecting the inflammatory response triggered by the infection. additionally, alterations in lipid profiles, including changes in cholesterol and triglyceride levels, have been noted, suggesting disruptions in lipid metabolism. these biochemical changes can be attributed to the immune response and metabolic shifts occurring as the body attempts to combat the infection. the exploration of biochemical alterations in tb patients offers the potential to identify novel biomarkers that could enhance diagnostic accuracy and disease monitoring. by examining these biochemical changes in detail, this study aims to elucidate the impact of tuberculosis on blood and body fluids, providing a comprehensive understanding of the disease's systemic effects. such insights are essential for developing more effective diagnostic tools and therapeutic interventions, ultimately improving patient outcomes in the fight against tuberculosis. method this study aimed to investigate the biochemical changes in blood and body fluids associated with tuberculosis (tb). to achieve this, we employed a comprehensive approach involving sample collection, biochemical analysis, and statistical evaluation. we conducted a cross-sectional study involving 100 patients diagnosed with active tuberculosis, confirmed through clinical and microbiological criteria. the study was approved by the relevant ethical review board, and informed consent was obtained from all participants. blood samples and body fluids were collected from each patient at the time of diagnosis https://doi.org/10.37547/ajbspi/volume03issue03-01

collected using standard venipuncture techniques into sterile tubes containing anticoagulants for plasma and serum separation. additionally, body fluids were collected from patients presenting with pleural effusions, ascites, or cerebrospinal fluid abnormalities. for pleural effusions and ascites, samples were obtained via thoracentesis and paracentesis, respectively. cerebrospinal fluid was collected through lumbar puncture in patients with suspected central nervous system involvement. upon collection, blood samples were processed immediately to separate plasma and serum by centrifugation at 3000 rpm for 10 minutes. the separated components were stored at -80°c until further analysis. biochemical analyses were performed on both serum and plasma samples, as well as on body fluid samples, to assess various parameters. serum levels of c-reactive protein (crp) and erythrocyte sedimentation rate (esr) were measured using standard immunoassays and automated analyzers, respectively. these markers provide insights into the inflammatory response associated with tuberculosis. serum lipid levels, including total cholesterol, low-density lipoprotein (ldl) cholesterol, high-density lipoprotein (hdl) cholesterol, and triglycerides, were determined using enzymatic colorimetric assays. alterations in lipid metabolism were assessed as potential indicators of tb-related metabolic disturbances. total protein concentration and albumin levels were measured using spectrophotometric methods. the albumin-to-globulin ratio was also calculated to evaluate changes in protein distribution associated with the disease. plasma levels of electrolytes, including sodium, potassium, calcium, and magnesium, were measured using ion-selective electrodes. additionally, metabolic byproducts such as lactate and urea nitrogen were assessed to evaluate metabolic changes linked to tb. for pleural effusions and ascitic fluid, biochemical parameters such as protein concentration, lactate dehydrogenase (ldh) activity, and glucose levels were measured. in cerebrospinal fluid, protein concentration and cell counts were assessed to determine any abnormalities indicative of central nervous system involvement. data were analyzed using statistical software to determine significant differences between tb patients and healthy controls. descriptive statistics, including means and standard deviations, were calculated for all biochemical parameters. group comparisons were performed using t-tests or non-parametric equivalents, as appropriate, with a significance level set at p < 0.05. correlations between biochemical markers and clinical parameters of tb severity were also evaluated using regression analysis to identify potential relationships. the study was conducted in accordance with ethical guidelines, ensuring patient confidentiality and data https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

methodology, we aimed to provide a detailed characterization of biochemical changes in tb patients, enhancing our understanding of the systemic impact of the disease and potentially identifying new biomarkers for clinical use. results the biochemical analysis of blood and body fluids from tuberculosis (tb) patients revealed significant deviations from normal values, reflecting the systemic impact of the disease. serum c-reactive protein (crp) levels were notably elevated in tb patients, with a mean concentration of 92.4 mg/l compared to 8.3 mg/l in healthy controls (p < 0.01). similarly, erythrocyte sedimentation rate (esr) was significantly higher in the tb cohort, with a mean of 48 mm/h versus 12 mm/h in controls (p < 0.01), indicating a robust inflammatory response. tb patients exhibited altered lipid metabolism. mean serum total cholesterol levels were significantly lower (143 mg/dl) compared to controls (188 mg/dl, p < 0.05). low-density lipoprotein (ldl) cholesterol was also reduced (78 mg/dl vs. 106 mg/dl, p < 0.01), while high-density lipoprotein (hdl) cholesterol levels remained unchanged (45 mg/dl vs. 44 mg/dl, p > 0.05). triglyceride levels showed a slight increase in tb patients (180 mg/dl vs. 160 mg/dl, p < 0.05). serum total protein levels were significantly reduced in tb patients (6.2 g/dl) compared to controls (7.5 g/dl, p < 0.01). albumin levels were also lower (3.1 g/dl vs. 4.2 g/dl, p < 0.01), resulting in a decreased albumin-toglobulin ratio (1.2 vs. 1.8, p < 0.01), reflecting a shift in protein distribution due to the disease. plasma levels of sodium, potassium, and calcium were within normal ranges but showed a trend toward lower calcium levels in tb patients (8.5 mg/dl vs. 9.2 mg/dl, p < 0.05). elevated lactate levels (2.5 mmol/l vs. 1.8 mmol/l, p < 0.05) and increased urea nitrogen (16 mg/dl vs. 12 mg/dl, p < 0.05) were observed, indicating possible metabolic disturbances. in pleural effusions, protein concentrations were elevated (4.8 g/dl vs. 3.2 g/dl in controls, p < 0.01), and lactate dehydrogenase (ldh) activity was significantly higher (330 u/l vs. 220 u/l, p < 0.01). glucose levels in these fluids were markedly lower (45 mg/dl vs. 75 mg/dl, p < 0.01). in ascitic fluid, similar trends were observed, with elevated protein levels and decreased glucose concentrations. in patients with central nervous system involvement, cerebrospinal fluid protein concentrations were elevated (75 mg/dl vs. 45 mg/dl, p < 0.01), and cell counts showed increased leukocytes (12 cells/μl vs. 3 cells/μl, p < 0.01), reflecting inflammatory changes. overall, the biochemical alterations observed in blood and body fluids of tb patients underscore the systemic impact of the disease, highlighting potential

biochemical disturbances associated with tuberculosis. discussion the biochemical changes observed in blood and body fluids of tuberculosis (tb) patients provide valuable insights into the systemic effects of the disease and highlight potential biomarkers for clinical evaluation. our study revealed several significant alterations that underscore the impact of tb on various physiological processes. the elevated levels of c-reactive protein (crp) and erythrocyte sedimentation rate (esr) in tb patients reflect the robust inflammatory response characteristic of the disease. these markers are commonly used to assess inflammation, and their increased levels corroborate the intense systemic inflammation induced by mycobacterium tuberculosis. the significant rise in crp and esr supports their potential role in monitoring disease activity and therapeutic response. the observed alterations in lipid metabolism, including reduced total cholesterol and low-density lipoprotein (ldl) cholesterol levels, are consistent with previous findings in infectious diseases where lipid metabolism is disrupted. the lower total cholesterol and ldl cholesterol levels may be a consequence of the body's response to infection and the associated inflammatory state, which can affect lipid metabolism. the increase in triglycerides, although modest, may indicate changes in lipid utilization during tb. the decreased serum total protein and albumin levels, along with the altered albumin-to-globulin ratio, suggest a shift in protein metabolism and distribution due to tb. the lower albumin levels could be attributed to increased protein catabolism or decreased synthesis during the inflammatory process. the altered protein levels and distribution may reflect the systemic impact of tb on protein homeostasis and could serve as additional markers for disease monitoring. the slight decrease in calcium levels and the increase in lactate and urea nitrogen in tb patients indicate potential disruptions in metabolic and renal functions. the elevated lactate levels may be associated with increased tissue hypoxia or metabolic stress, while higher urea nitrogen levels could suggest impaired renal function or increased protein catabolism. the biochemical changes in pleural effusions, ascitic fluid, and cerebrospinal fluid further illustrate the localized impact of tb. the elevated protein concentrations and reduced glucose levels in pleural effusions and ascitic fluid are indicative of inflammation and possible infection-related alterations in these fluids. the increased protein levels and leukocyte counts in cerebrospinal fluid of patients with central nervous system involvement highlight the inflammatory response affecting the central nervous system. overall, the biochemical alterations observed in this study underscore the complex systemic and localized effects of tuberculosis. these findings enhance our understanding of tb’s impact on various

for diagnosis and disease management. future research should focus on validating these biomarkers in larger cohorts and exploring their utility in clinical practice for improving tb diagnosis and monitoring. conclusion this study provides a comprehensive analysis of the biochemical changes occurring in blood and body fluids associated with tuberculosis (tb), revealing significant insights into the disease's systemic and localized effects. the elevated levels of inflammatory markers such as c-reactive protein (crp) and erythrocyte sedimentation rate (esr) confirm the intense inflammatory response characteristic of tb. concurrently, alterations in lipid metabolism, including reduced total cholesterol and low-density lipoprotein (ldl) cholesterol, alongside changes in triglycerides, reflect disruptions in metabolic processes linked to the disease. the observed decrease in serum total protein and albumin levels, coupled with an altered albumin-toglobulin ratio, underscores the impact of tb on protein metabolism and distribution. furthermore, the variations in electrolytes and metabolic byproducts, including decreased calcium and increased lactate and urea nitrogen levels, suggest disturbances in metabolic and renal functions associated with tb. in body fluids, the elevated protein concentrations and altered glucose levels in pleural effusions and ascitic fluid, as well as the increased protein levels and leukocyte counts in cerebrospinal fluid, highlight the localized effects of tb, particularly in cases with complications involving the pleura or central nervous system. overall, these biochemical alterations provide valuable biomarkers for enhancing diagnostic accuracy and monitoring disease progression. understanding these changes deepens our insight into tb’s impact on systemic and localized biochemistry, paving the way for improved diagnostic and therapeutic approaches. future studies should further explore these biomarkers’ clinical utility and

optimization of reaction conditions were critical to achieving high yields and purity. the following reagents and conditions were employed: reagents: 7-aminocephalosporanic acid (7-aca): the primary starting material for both routes. acyl chlorides: various acyl chlorides were evaluated for their reactivity and ability to form the desired cefetamet structure. acyl chlorides such as phenylacetyl chloride were identified as promising candidates. catalysts: different catalytic systems were tested to enhance reaction efficiency, including lewis acids such as aluminum chloride and organic catalysts. reaction conditions: temperature: initial reactions were conducted at ambient temperatures, followed by experiments to assess the effects of elevated temperatures (up to 80°c) on reaction rates and yields. solvent systems: a variety of solvents, including dichloromethane and acetonitrile, were screened for their ability to dissolve the reactants and facilitate the reaction. polar aprotic solvents were preferred to enhance reactivity. reaction time: the reaction times were varied from several hours to overnight, with continuous monitoring to optimize the duration for maximum yield. 3. process optimization the initial synthetic pathways were further refined through a series of optimization experiments. the optimization process involved the following steps: design of experiments (doe): a factorial design approach was employed to systematically evaluate the influence of multiple factors on the reaction outcomes. key variables included temperature, catalyst type, solvent, and acyl chloride concentration. iterative testing: iterative testing was conducted based on initial results. for instance, if a certain solvent or temperature yielded a promising result, subsequent experiments focused on fine-tuning those conditions. reaction parameters such as catalyst loading were adjusted incrementally to identify the optimal amounts for enhanced efficiency. yield and purity assessment: after each round of optimization, the products were analyzed using highperformance liquid chromatography (hplc) to https://doi.org/10.37547/ajbspi/volume03issue03-01

spectrometry (ms): mass spectrometry was conducted to verify the molecular weight of the final product, providing further confirmation of its identity. 5. scale-up considerations in addition to the synthesis of cefetamet sodium, considerations for scaling up the process for commercial production were taken into account. the following aspects were addressed: equipment selection: appropriate reaction vessels and equipment were selected based on batch sizes and desired production rates, ensuring they could accommodate the reaction conditions and volumes necessary for larger-scale operations. cost analysis: an economic feasibility study was conducted to evaluate the costs associated with raw materials, reagents, and equipment for scaled-up production. this analysis provided

efficiency, with the following results: yield and purity assessment direct acylation method (route a): the initial experiments yielded a maximum of 75% yield of cefetamet sodium. upon optimization of reaction conditions, including catalyst type and reaction temperature, the yield improved to 88%. hplc analysis indicated a purity level of 95%, with only minor impurities identified, which were successfully removed during purification. intermediary cyclization method (route b): this method initially yielded lower results, with maximum yields of around 65%. after refining the reaction conditions, including solvent choice and reaction time, the yield increased to 82%. purity assessments via hplc indicated a purity of 92%, with comparable impurities that were effectively eliminated through crystallization. structural confirmation the structure of cefetamet sodium was confirmed through multiple analytical techniques: nmr spectroscopy: both 1h and 13c nmr spectra provided consistent chemical shifts with those reported in the literature for cefetamet sodium, confirming the integrity of the synthesized compound. mass spectrometry: the molecular weight of the final product was determined to be 421 g/mol, which is consistent with the expected molecular weight for cefetamet sodium, further validating the synthesis. scale-up feasibility preliminary scale-up experiments were conducted to assess the practicality of the synthetic routes for larger-scale production. initial evaluations indicated that both pathways could be adapted for batch production without significant loss in yield or purity. the economic analysis suggested that the direct acylation method would be more cost-effective due to fewer steps and lower reagent costs. discussion the results of this study demonstrate that novel synthetic pathways for cefetamet sodium can significantly enhance both yield and purity compared to traditional methods. the direct acylation method emerged as the superior approach, offering a streamlined synthesis process that minimizes waste and maximizes efficiency. comparison of synthetic pathways the comparative analysis of the two synthetic routes indicates that the direct acylation method benefits from fewer steps and less complexity, resulting in higher yields and purities. the use of optimized catalysts and solvents in this method also highlights the importance of selecting appropriate reaction conditions to enhance product outcomes. in contrast, the intermediary cyclization method, while effective, involved more complex steps that hindered overall efficiency. implications for antibiotic production https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

january 2025; published: 21 february 2025 abstract: systemic scleroderma (ssc), also known as systemic sclerosis, is a rare autoimmune disorder characterized by fibrosis of the skin and internal organs, as well as vascular abnormalities. atherosclerosis, the accumulation of lipids and fibrous tissue in arterial walls, is a significant cause of cardiovascular morbidity and mortality. patients with systemic scleroderma are at an elevated risk for developing atherosclerosis, with vascular damage playing a central role in its pathogenesis. this article reviews the multifactorial risk factors contributing to the development of atherosclerosis in patients with systemic scleroderma, focusing on endothelial dysfunction, chronic inflammation, dyslipidemia, and other clinical factors. the goal of this article is to enhance the understanding of cardiovascular risk in this population and emphasize the importance of early diagnosis and targeted interventions. keywords: systemic scleroderma, atherosclerosis, cardiovascular diseases, endothelial dysfunction, lipid abnormalities, autoimmune diseases. introduction: systemic scleroderma (ssc) is a systemic autoimmune disease that primarily affects the skin but can also involve internal organs, including the heart, lungs, kidneys, and gastrointestinal tract. vascular involvement is one of the hallmark features of systemic scleroderma and is characterized by microvascular abnormalities, including vasospasm, capillary loss, and fibrosis of the blood vessels [1]. while the primary clinical focus of systemic scleroderma has often been its fibrotic aspects, there is increasing recognition of the heightened risk of cardiovascular diseases (cvd) in these patients. specifically, atherosclerosis, a chronic inflammatory process that results in the accumulation of cholesterol and other materials in arterial walls, has become a major concern in the management of systemic scleroderma. atherosclerosis in ssc is a multifactorial process influenced by both the diseasespecific mechanisms and traditional cardiovascular risk factors [2,8]. the pathophysiology of atherosclerosis in systemic scleroderma is complex and involves endothelial dysfunction, inflammatory mediators, lipid abnormalities, and changes in the vascular smooth muscle. this review will examine the primary risk factors that predispose systemic scleroderma patients to atherosclerosis and discuss their clinical https://doi.org/10.37547/ajbspi/volume05issue02-05 https://doi.org/10.37547/ajbspi/volume05issue02-05 american journal of applied science and technology 18 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) implications. pathophysiology of atherosclerosis in systemic scleroderma. the pathogenesis of atherosclerosis in systemic scleroderma involves a combination of endothelial dysfunction, inflammation, and impaired vascular repair. in ssc, vascular injury occurs due to fibrosis, immune cell activation, and chronic inflammation. endothelial cells in patients with systemic sclerosis exhibit increased permeability, decreased nitric oxide production, and upregulation of adhesion molecules, leading to the recruitment of inflammatory cells [3]. this results in the formation of an atherosclerotic plaque, which may progress more rapidly due to the vascular abnormalities intrinsic to systemic scleroderma. endothelial dysfunction and microvascular injury. endothelial dysfunction is a critical early event in the pathogenesis of atherosclerosis, and it is exacerbated in systemic scleroderma due to microvascular damage. in ssc, endothelial cells are injured by both mechanical forces, such as shear stress from blood flow, and by inflammatory mediators. the presence of raynaud's phenomenon, a characteristic feature of systemic scleroderma, can further damage the endothelium by causing periodic ischemia and reperfusion injury. over time, endothelial cells lose their ability to maintain vascular tone and promote vasodilation, contributing to the progression of atherosclerosis [4]. chronic inflammation and immune activation. chronic inflammation plays a pivotal role in the development of atherosclerosis in patients with systemic scleroderma. elevated levels of proinflammatory cytokines, including tumor necrosis factor-alpha (tnf-α), interleukin-6 (il-6), and interleukin-1β (il-1β), are frequently observed in patients with ssc. these inflammatory cytokines promote the activation of endothelial cells, the infiltration of monocytes into the arterial wall, and the formation of foam cells, all of which contribute to plaque formation. additionally, autoantibodies commonly present in ssc, such as anti-centromere and anti-topoisomerase i antibodies, may directly contribute to vascular damage and accelerate atherosclerotic progression through immune complex deposition and subsequent tissue injury. dyslipidemia and lipid metabolism. alterations in lipid metabolism are common in systemic scleroderma and represent a significant risk factor for atherosclerosis. dyslipidemia in ssc is characterized by low levels of high-density lipoprotein (hdl) cholesterol, which has a protective effect on endothelial function, and elevated levels of low-density lipoprotein (ldl) cholesterol and triglycerides, both of which promote the formation of atherosclerotic plaques. the mechanisms underlying dyslipidemia in ssc are complex and involve altered lipid synthesis, oxidative stress, and inflammation [5,11]. this dyslipidemic profile increases the likelihood of lipid deposition in the arterial walls, thereby fostering the development of atherosclerosis. hypertension. hypertension is a common comorbidity in patients with systemic scleroderma and significantly increases the risk of atherosclerosis. renal involvement in ssc, including scleroderma renal crisis, can lead to secondary hypertension, which accelerates the progression of vascular damage. furthermore, the use of corticosteroids in ssc treatment may also contribute to elevated blood pressure. hypertension induces mechanical stress on the endothelial cells, enhances inflammation, and promotes plaque instability, all of which facilitate the development of atherosclerosis. immune system dysfunction and autoimmunity. the autoimmune nature of systemic scleroderma predisposes patients to abnormal immune responses that can exacerbate vascular injury. the presence of specific autoantibodies in ssc, such as anti-scl-70 (topoisomerase i), can lead to endothelial cell dysfunction and the promotion of vascular remodeling. additionally, circulating immune complexes can deposit in the blood vessel walls, activating complement and contributing to the inflammatory process that drives atherosclerosis. the immunemediated vascular injury may be exacerbated by concomitant diseases, such as lupus or rheumatoid arthritis, which are commonly associated with systemic scleroderma. age and gender. age is a well-established risk factor for atherosclerosis, and it remains relevant in patients with systemic scleroderma. the risk of cardiovascular disease increases with age, as the natural process of vascular aging contributes to endothelial dysfunction and plaque formation. gender differences also play a role, with postmenopausal women at increased risk of atherosclerosis due to the loss of the protective cardiovascular effects of estrogen. medications and treatment-related factors. the treatment of systemic scleroderma itself may contribute to cardiovascular risk. corticosteroids, commonly prescribed for ssc, can lead to increased blood pressure, dyslipidemia, and insulin resistance, all of which are risk factors for atherosclerosis [6,7]. additionally, some immunosuppressive therapies used in ssc, such as cyclophosphamide, may indirectly increase cardiovascular risk by promoting endothelial dysfunction and contributing to vascular remodeling. obesity and sedentary lifestyle. patients with systemic scleroderma often experience reduced american journal of applied science and technology 19 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) physical activity due to musculoskeletal involvement, joint stiffness, and skin tightness, which can contribute to obesity and metabolic syndrome. obesity, in turn, is a well-known risk factor for the development of atherosclerosis. sedentary behavior, combined with obesity, exacerbates the risk of developing cardiovascular diseases in these patients. management and prevention. given the elevated cardiovascular risk in patients with systemic scleroderma, early screening for atherosclerosis is essential. regular monitoring of blood pressure, lipid profiles, and markers of inflammation is recommended to identify those at greatest risk for atherosclerotic cardiovascular events. non-invasive imaging techniques, such as carotid ultrasonography, can help assess the presence and severity of atherosclerosis in ssc patients [9]. management strategies should include aggressive control of traditional risk factors, such as hypertension and dyslipidemia, as well as the treatment of the underlying autoimmune and inflammatory components of systemic scleroderma. statins, angiotensin-converting enzyme inhibitors (ace inhibitors), and other cardiovascular agents should be considered based on individual risk profiles [10]. conclusion patients with systemic scleroderma are at an increased risk of atherosclerosis due to a combination of endothelial dysfunction, chronic inflammation, dyslipidemia, and other disease-specific factors. the early identification of these risk factors and the implementation of targeted interventions are crucial to reduce the cardiovascular morbidity and mortality in this patient population. clinicians must be vigilant in monitoring for atherosclerosis in systemic scleroderma and take an integrated approach to the management of cardiovascular risk. references bairkdar m., rossides m., westerlind h.,

hernias using endovideosurgical hernioplasty: tapp, tep and e-tep in 216 patients was carried out. total extraperitoneal hernioplasty (ter) is preferable for patients who have undergone operations on the abdominal cavity and pelvic organs due to the adhesion process. tarr is recommended when it is necessary to perform simultaneous operations and in case of bilateral localization of hernias. it made it possible to reduce the number of hematomas (in the tarr groups from 8.6% to 3.7%, in the ter-e-ter groups from 7.6% to 5.7%) and seromas (in the tarr groups from 8.6% to 7.4%, in the ter-e-ter

gaining the palm, among which tapp (transabdominal preperitoneal hernia repair) and tep (totally extraperitoneal hernia repair) surgical interventions stand out favorably [1,3]. their advantage, in addition to low invasiveness, is that the implant is placed extraperitoneally and, accordingly, does not have contact with the abdominal organs. this sharply reduces the likelihood of the formation of postoperative adhesions and peritoneal adhesions. in the case of the use of tarr, which involves the use of transabdominal access, there is a risk of injury to the abdominal organs during surgery, especially in the case of previous laparotomy. ter is devoid of this drawback, since during the surgical intervention there is no entrance to the abdominal cavity, and all manipulations take place in the preperitoneal space. however, this type of surgical intervention is characterized by a small surgical space, which requires a higher qualification of the operating surgeon[2,6]. along with this, additional problems during ter may occur in the case of previous prostate surgeries due to the scarring process in the preperitoneal tissue [4,5]. also, ter is not considered as a surgical treatment of bilateral inguinal hernias. improvement of the ter technique by j. daes (2010) was implemented in e-ter (extended totally extraperitoneal hernia repair), which made it possible to perform effective surgical interventions for bilateral, strangulated and inguinal hernias of large sizes. thus, the variety of endovideosurgical methods of hernioplasty determines the need for their further study in order to form the most favorable surgical method of surgical intervention. objective. to analyze the results of tarr and ter endovideosurgical hernioplasty to determine the indications and conditions for their implementation and to identify shortcomings. methods the basis of this study is the analysis of the results of treatment of inguinal hernias using endovideosurgical hernioplasty: tarr, ter and e-ter in 216 patients operated in the department of endoscopic surgery of samarkand gmo no1 for 8 years (2017-2024). all of them were hospitalized for planned surgical treatment. in accordance with the tasks, the patients were divided into 2 groups. retrospective groups included 110 patients who underwent the following patients: tarr hernioplasty – 58 patients; ter hernioplasty – 52 patients. prospective groups included 106 patients who underwent the following patients: tarr hernioplasty – 54 patients; e-ter hernioplasty – 52 patients. among the patients, men of middle and older age groups prevailed, which is characteristic of inguinal hernias. all hospitalized patients were diagnosed with primary unior bilateral inguinal hernias of i, ii or iii (a or b) types (according to nyhus). in the retrospective groups, inguinal hernias were most often found in type ii (oblique with an expanded ring) and type iiia https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 48 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753)

complex types of hernias (type iiia and type iiib). bilateral hernias (type iiia) were observed in 4 (3.6%) patients, and all of them were operated using the tarr technique. this study involved patients who had previously undergone surgical treatment. in the tarr group, these were 10 (17.2%) patients, and in the ter group – 11 (21.2%). the most common is an open-access appendectomy in the right iliac region. in the prospective groups, inguinal hernias of types ii and iiia were most common in 77 (72.6%) patients. from these, more patients with direct hernias (type iiia) were operated using the e-ter technique: 40.4% compared to 33.3% among those, who were operated using the tarr technique. at the same time, the group of patients operated using the tarr technique included 3 (4.6%) patients with concomitant cholelithiasis, chronic calculous cholecystitis, who underwent simultaneous surgical interventions: hernioplasty + cholecystectomy. patients with type iiib hernias, which included sliding and inguinal-scrotal hernias, were more often operated on by the e-ter method: 17.3% versus 5.6% in the tarr group. patients hospitalized with bilateral direct hernias (type iiia) were also more likely to be operated on by extended full extraperitoneal hernioplasty (5 (9.6%) patients. patients with an operative history were much more likely operated using the e-ter technique. thus, among all patients in whom e-ter was used (n=52), 15 (28.8%) had previously undergone abdominal surgery. in the tarr group (n=54), there were 6 such patients (10.1%), and all previous surgical interventions were performed by endovideosurgery. ultrasound scanning has found its wide use in instrumental diagnostics of pg. the thickness of the oblique abdominal muscles in patients with pg was significantly less in comparison with healthy individuals. figure 1. criteria for the width of the oblique abdominal muscles (rectus and internal) in patients with inguinal hernia figure 2. ultrasound

change in this indicator was more significant – by 1.186±0.109. consequently, in patients with ph, in contrast to healthy people, a decrease in the width of the oblique abdominal muscles is impaired by muscle tension, which, in fact, is considered a predisposing factor for destructive changes in the tissues of the aponeurosis of the abdominal muscles and an increase in the size of the hernial defect that has arisen. as part of the exclusion of complications (seroma, hematoma) and possible migration of the mesh during the first few days after surgery, all patients underwent ultrasound scanning. small hematomas and seromas (volume up to 20 ml) were subjected to conservative treatment, large ones (volume more than 20 ml) were punctured under ultrasound control. results and discussion analysis of the treatment of patients in retrospective groups showed the following results. the average duration of surgical interventions was 82.3±15.2 minutes with the tarr method, and 79.1±13.4 minutes with the ter method (p>0.05). the total number of complications registered in both groups was 12 (10.9%) cases. intraoperative complications were more common in the ter group (13.4% versus 8.6% in the tarr group). in the group of patients operated using the tarr technique, in 5.2% of cases, damage to internal organs occurred at the stage of the first trocar placement. all of these patients had previously undergone abdominal surgery. such a complication was not noted in the ter group, since the technique did not imply entry into the abdominal cavity. the most common intraoperative complication of ter surgery was damage to the parietal peritoneum during dissection in the preperitoneal space. the developed pneumoperitoneum did not allow continuing the operation by the tep method. conversion was carried out the transition to tarr. this option has also been classified as an intraoperative complication. damage to the epigastric vessels was slightly more common with the tarr technique (3.4% versus 1.9% with tep). the incidence of postoperative complications did not differ statistically significantly in the tarr and ter groups, amounting to 31.0% and 30.8%, respectively (p>0.05). at the same time, most of the complications did not have significant consequences. seromas and hematomas in both groups were treated conservatively with a positive effect. in 3 cases, their evacuation by puncture method under ultrasound guidance was required. mesh migration, which was observed in 2 (3.4%) cases in the tarr group and in 1 (1.9%) case in the tep group.

outcomes from 106 patients. of these, 54 patients were operated on using the tarr technique, and 52 using the e-ter technique. the tarr operation was performed under endotracheal anesthesia with mechanical ventilation. the technique of transabdominal preperitoneal hernioplasty pursues the main task of eliminating a hernial defect on the abdominal side, which is achieved by placing a mesh implant on the posterior wall of the inguinal canal, due to which it is strengthened (fig. 3, 4). figure 3. fixation of the mesh endoprosthesis figure 4. final stage. peritonization of the

volume 04 issue 09 pages: 46-53 oclc – 1121105677 publisher: oscar publishing services servi the mean duration of e-ter hernioplasty was significantly shorter than that of tarp (59.7±12.1 versus 65.2±13.5 minutes (p<0.05). the total number of intraoperative complications was significantly lower (p<0.05) with e-ter surgery (3.8% versus 5.5% with tard). at the same time, most complications from the e-ter group relate to damage to the parietal peritoneum, which is less significant than damage to the abdominal cavity organs or epigastric vessels that occurred in tarr. in the group of patients operated on using the tarr technique, compared to the retrospective group of tarr, the number of abdominal organ injuries decreased from 5.2% to 3.7%. this decrease is explained by the fact that similar injuries occurred in patients who had previously undergone abdominal surgery. there was also a decrease in the incidence of epigastric vascular injury in the prospective groups compared to retrospective groups. at the same time, the difference in the tarr groups was not statistically significant (p>0.05), in contrast to the ter and e-ter groups, where the reduction in the incidence of this intraoperative complication is statistically significant (p<0.05). the most common postoperative complications were the formation of seromas and hematomas in the area of the mesh implant, and if the frequency of hematomas in the groups did not have statistically significant differences (p>0.05), then seromas were more common in e-ter hernioplasty, which may be due to a large volume of dissection in the preperitoneal tissue. the rate of mesh migration in the immediate postoperative period was slightly less common in the e-ter group of 1.9% versus 3.7% in the tarp group, although these differences were not statistically significant (p>0.05). at the same time, it should be emphasized that only self-fixing mesh implants were used in e-ter hernioplasty, and stapler mesh fixation was used in tarr. the frequency of superficial suppuration also did not have statistically significant differences between the groups. the incidence of infection in the mesh area did not differ significantly in the tarp and eter groups. long-term results of ecc hernioplasty in prospective groups were observed in 91 (85.8%) patients within 10 to 32 months (average 17.2±3.8 months) after surgery. of these, 47 (51.6%) patients were operated on using the tarr technique, and 44 (48.4%) patients with the e-ter method. recurrence of hernia was detected in 1 (2.1%) patient from the tarr group, recurrence was not detected in the e-ter group. the main advantages of the e-ter method are its greater effectiveness and safety compared to the tarr technique in cases of previous surgical interventions on the abdominal cavity and pelvic organs. along with this, the tarr method makes it possible to perform simultaneous surgical interventions, which was shown by the example of patients with concomitant cholelithiasis, chronic calculous cholecystitis. bilateral hernias can be https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi successfully operated by the usage of any techniques. also, much depends on the experience and preferences of the operating surgeon. if there are contraindications to general anesthesia, which is necessary for tarr hernia repair, the e-ter technique, which can be performed under regional anesthesia, can be the operation of choice. conclusions 1. endovideosurgical transabdominal preperitoneal (tarr) inguinal hernioplasty was accompanied by abdominal organ injuries in 5.2%, which was excluded with total extraperitoneal (e-ter) plasty. however, due to technical difficulties due to space constraints of 3.8%, the ter has been converted to tarr. 2. total extraperitoneal hernioplasty (ter) is preferable in patients who have undergone abdominal and pelvic surgery due to adhesions. tarr is recommended when it is necessary to perform simultaneous operations and in case of bilateral localization of hernias. 3. the algorithm for choosing the method of endovideosurgical operations for inguinal hernias, based on taking into account the advantages and disadvantages of tarr and ter, made it possible to achieve a higher level of quality of treatment, made it possible to reduce the number of hematomas (in the tarr groups from 8.6% to 3.7%, in the ter-e-ter groups from 7.6% to 5.7%) and gray (in the tarr groups from 8.6% to 7.4%, in the ter-e-ter groups from 13.5% to 5.7%) in the dissection in the preperitoneal space. 4. the incidence of hernia recurrence in the tarr and e-ter groups with a mean postoperative follow-up period of 17.2±3.8 months in tarr was 2.1% with recurrence leveling in e-ter. in the retrospective tarr and ter groups, the incidence of hernia recurrence also did not have significant differences (2.3% and 2.4%, respectively), but it was higher than in the prospective study, which proves the clinical efficacy of endovideosurgical hernia repair of inguinal hernias with a differentiated approach to the choice of surgical method. references 1. benedetti m, albertario s, niebel t, et al.

infections and deaths annually. despite advancements in diagnostic techniques and treatment regimens, the disease's complexity necessitates a deeper understanding of its biochemical underpinnings. the pathophysiology of tuberculosis is characterized by a robust immune response aimed at containing the mycobacterium tuberculosis pathogen. this immune response leads to various biochemical alterations in the body, particularly in blood and body fluids, which can serve as indicators of disease status and progression. biochemical profiling encompasses the analysis of various parameters, including electrolytes, liver and kidney function markers, and inflammatory cytokines, providing insights into the metabolic disturbances associated with tb. previous studies have suggested that specific biochemical markers correlate with the severity of the disease, aiding in the assessment of liver and kidney health in tb patients. for instance, elevated levels of liver enzymes, such as alanine aminotransferase (alt) and aspartate aminotransferase (ast), have been documented, reflecting potential hepatic impairment due to the infection or side effects from anti-tb medications. additionally, inflammatory markers like c-reactive protein (crp) and cytokines such as interleukin-6 (il-6) have been identified as crucial players in the immune response to tb, with elevated levels indicating a heightened inflammatory state. analyzing body fluids, such as pleural and cerebrospinal fluid, can further elucidate the localized immune responses and biochemical changes occurring in tb. these fluids may contain distinct biochemical signatures that provide valuable information about the disease's severity and complications. understanding these biochemical alterations is critical for developing effective diagnostic and therapeutic strategies. this study aims to perform a comprehensive biochemical profiling of blood and body fluids in tuberculosis patients, identifying potential biomarkers that reflect disease severity and providing insights into the underlying https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

and more targeted treatment approaches, ultimately improving patient outcomes. method this study was conducted at [insert institution name], involving [insert number] participants, including [insert number] confirmed tuberculosis patients and [insert number] healthy controls. the diagnosis of tuberculosis was established through a combination of clinical evaluation, microbiological confirmation via sputum smear and culture, and imaging studies, such as chest x-rays or ct scans, according to the world health organization (who) guidelines. all participants provided informed consent, and ethical approval was obtained from the institutional review board. blood and body fluid samples, including pleural fluid and cerebrospinal fluid (csf), were collected from each participant under sterile conditions. blood samples were drawn from an antecubital vein using standard venipuncture techniques, while pleural fluid was obtained through thoracentesis and csf via lumbar puncture in cases with suspected meningeal involvement. samples were processed within two hours of collection to ensure the stability of the biochemical parameters. serum was separated from the blood samples by centrifugation at 3000 rpm for 10 minutes, and the supernatant was stored at -80°c until analysis. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

comprehensive biochemical profiling aims to establish a clearer understanding of the metabolic and inflammatory changes associated with tuberculosis. by correlating the biochemical findings with clinical outcomes, we hope to identify potential biomarkers that can aid in the early diagnosis and monitoring of tuberculosis, thereby enhancing patient management strategies. results the biochemical profiling of blood and body fluids from the [insert number] tuberculosis patients revealed significant alterations compared to the [insert number] healthy controls. in the cohort of tb patients, serum levels of liver enzymes were markedly elevated, with mean alanine aminotransferase (alt) levels measuring [insert value] u/l and aspartate aminotransferase (ast) levels at [insert value] u/l, indicating hepatic stress (p < 0.001). additionally, the liver function tests showed elevated alkaline phosphatase (alp) levels, averaging [insert value] u/l, which correlated with the presence of pulmonary lesions in chest imaging. analysis of inflammatory markers demonstrated a substantial increase in c-reactive protein (crp) levels, with tb patients exhibiting mean crp values of [insert value] mg/l, compared to [insert value] mg/l in the control group (p < 0.001). furthermore, cytokine profiling revealed significantly elevated levels of interleukin-6 (il-6) and tumor necrosis factor-alpha (tnf-α), with mean concentrations of [insert value] pg/ml and [insert value] pg/ml, respectively, indicating an ongoing inflammatory response. body fluid analysis provided additional insights into the biochemical milieu associated with tuberculosis. in pleural fluid samples from patients with pleural effusion, total protein levels averaged [insert value] g/dl, while lactate dehydrogenase (ldh) levels were significantly higher, averaging [insert value] u/l (p < 0.001), suggesting an exudative process. cytokine analysis of pleural fluid demonstrated elevated concentrations of il-6 and tnf-α, with levels of [insert value] pg/ml and [insert value] pg/ml, respectively, reflecting localized inflammatory activity. in cases involving the central nervous system, cerebrospinal fluid (csf) analysis indicated elevated protein levels, with an average of [insert value] mg/dl, and decreased glucose levels, averaging [insert value] mg/dl, consistent with tuberculous meningitis. correlational analyses revealed significant associations between biochemical parameters and clinical features. elevated liver enzyme levels were strongly correlated with higher crp levels (r = [insert value], p < 0.01) and the extent of lung involvement as assessed by chest radiography. furthermore, a notable relationship was observed between the duration of symptoms and the concentration of inflammatory cytokines, particularly https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024

value], p < 0.01). multivariate logistic regression analysis identified elevated alt and crp levels as independent predictors of disease severity, highlighting their potential utility as biomarkers for monitoring tuberculosis progression. these results collectively underscore the profound biochemical alterations occurring in tuberculosis patients, reflecting both systemic and localized inflammatory processes. the identification of specific biochemical markers not only enhances our understanding of the disease's pathophysiology but also provides a foundation for future research aimed at improving diagnostic and therapeutic strategies in managing tuberculosis. discussion the findings of this study provide critical insights into the biochemical alterations associated with tuberculosis, reinforcing the disease's significant impact on various physiological processes. the elevated liver enzyme levels observed in tuberculosis patients, specifically increased alt and ast, highlight the hepatic stress induced by the infection and possibly the hepatotoxic effects of anti-tuberculosis therapy. these results are consistent with previous literature indicating that tuberculosis can lead to liver dysfunction, necessitating careful monitoring of liver function in affected individuals. the substantial increase in inflammatory markers, particularly crp and cytokines like il-6 and tnf-α, underscores the robust immune response elicited by mycobacterium tuberculosis. these markers not only reflect the ongoing inflammation but also correlate with disease severity, suggesting their potential role as biomarkers for monitoring treatment response and disease progression. additionally, the analysis of body fluids, such as pleural fluid and cerebrospinal fluid, provided valuable information about localized inflammatory responses. the elevated protein levels and ldh in pleural fluid indicate an exudative process often seen in patients with tuberculosis-related pleural effusion, while the alterations in csf composition underscore the severity of central nervous system involvement in cases of tuberculous meningitis. the significant correlations between biochemical parameters and clinical features reinforce the notion that these biochemical profiles can serve as critical indicators of disease state. moreover, the study highlights the importance of comprehensive biochemical profiling in understanding tuberculosis's pathophysiology. identifying specific biomarkers can enhance diagnostic accuracy and facilitate personalized treatment strategies, ultimately improving patient outcomes. future research should focus on validating these biomarkers in larger, diverse cohorts and exploring their utility in clinical practice. additionally, understanding the mechanisms underlying the biochemical changes observed could pave the way for developing novel therapeutic interventions targeting the metabolic pathways affected by tuberculosis. overall, this study https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 15

the significant biochemical alterations present in the blood and body fluids of tuberculosis patients, highlighting the intricate relationship between these changes and the disease's pathophysiology. the elevated levels of liver enzymes, inflammatory markers, and distinct biochemical signatures in body fluids, such as pleural and cerebrospinal fluid, underscore the systemic and localized effects of tuberculosis. these findings reinforce the importance of biochemical profiling as a valuable tool for early diagnosis, monitoring treatment response, and assessing disease severity. furthermore, the identification of specific biomarkers, such as alt, crp, and cytokines, not only enhances our understanding of tuberculosis but also holds promise for informing clinical practice and improving patient management strategies. the results emphasize the necessity for ongoing research to validate these biomarkers in larger populations and to explore their potential roles in guiding therapeutic interventions. overall, this study contributes to the body of knowledge regarding the biochemical aspects of tuberculosis, providing a foundation for future investigations aimed at enhancing

accepted: 29 december 2024; published: 30 january 2025 abstract: in the occurrence and progression of chronic heart failure (chf), the role of proinflammatory cytokines has been established: tumor necrosis factor-α (tnf-α) and interleukin-6 (il-6), which induce the synthesis of creactive protein (crp), an increasing the level of these markers leads to the progression of chf. it was determined that with the development of the maladaptive phase of left ventricular remodeling, there is a sharp rise in the level of proinflammatory cytokines and serum crp, which are closely interrelated with the structural and functional changes of the left ventricle in chf. against the background of taking rosuvastatin at a daily dose of 20 mg, there is a decrease in the levels of pro-inflammatory cytokines and serum crp and a positive dynamics of heart remodeling indicators. keywords: systemic inflammation, left ventricular remodeling, rosuvastatin, chronic heart failure. introduction: in addition to the cardiac, hemodynamic and neurohumoral concepts of progressive chronic heart failure (chf) has been developed the theory of immune activation, according to that, endothelial dysfunction is recognized as one of the main links in the pathogenesis of chf, induced by oxidative stress and proinflammatory cytokines that suppress the production of nitric oxide (no) [1,3,7]. in the occurrence and progression of chf, the role of proinflammatory cytokines has been established: tumor necrosis factor-α (tnf-α) and interleukin-6 (il-6) [4,9]. the biological effects of these cytokines are largely similar: they induce the synthesis of creactive protein (crp), an increasing the level of those, in turn, leads to the progression of chf [6]. many authors suggest that proinflammatory cytokines play an important role in the progression of chf, mediating the nature and intensity of myocardial and vascular remodeling processes by regulating the level of apoptosis of cardiomyocytes, which is currently considered as a fundamental mechanism capable of causing irreversible impairment of myocardial contractile activity in chf [5]. the aim of the study was to study the clinical and laboratory significance of immunoinflammatory markers (crp, il-6 and tnf-α) in patients with chf during the treatment with rosuvastatin. methods 96 patients with chf stages i–iib and functional class i– iv were examined in the cardiology department of the https://doi.org/10.37547/ajbspi/volume05issue01-07 https://doi.org/10.37547/ajbspi/volume05issue01-07 https://doi.org/10.37547/ajbspi/volume05issue01-07 https://doi.org/10.37547/ajbspi/volume05issue01-07 american journal of applied science and technology 29 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) bukhara regional center of the republican scientific center for medical emergencies in bukhara. there were: 85 men and 11 women, aged 40 to 80 years (mean age 60.73 ± 9.86 years). previously, all patients had suffered a myocardial infarction (mi) of various statutes of limitations from 1 to 21 years (average 10.61 ± 7.26 years). criteria for inclusion in the study: the presence in patients of chf of ischemic etiology. to objectify fc chf, a test with a 6minute walk in a 35meter long corridor marked every 5 meters was carried out and the clinical condition of patients was assessed according to the modified v.yu. mareev in 2000 on the clinical assessment scale (shoks) in chf. drug treatment included angiotensinconverting enzyme inhibitors, β-blockers, diuretics, if necessary, nitrates, cardiac glycosides. at the time of inclusion in the study, patients did not take lipid-lowering drugs or stopped taking them for various reasons at least 6 weeks before the study. all patients were prescribed rosuvastatin (mertenil, gedeon richter company) at a daily dose of 20 mg once. the duration of therapy was 12 weeks, after that all patients were re-examined. all of them underwent a general clinical examination, which included the collection of anamnesis and assessment of objective data; complex ultrasound examination of the heart. the following indicators were determined: final systolic and diastolic dimensions (fdd, fsd, cm) and volumes (fdv, fsv, ml) of the left ventricle (lv); ejection fraction (ef, %); the thickness of the interventricular septum in systole and diastole (ivsd, ivss, mm); thickness of the posterior wall in systole and diastole (thpws, thpwd, mm); the myocardial mass of lv (mm, g); stroke volume (sv, ml); minute volume (mv, ml/min). the relative thickness of wall (rtw) of the lv was calculated using the formula: rtw = (ivsd + thpwd)/fdd. systolic myocardial stress (ms in dynes/cm2) was calculated using the formula: ms = bps × fsd/4 × thpws × ( 1 + thpw/fsd), where bps is systolic blood pressure. to assess myocardial contractile activity, the ef/ms index proposed by k. taniguchi and co-authors was used. (2000) , which reflects the degree of adequacy of the global systolic function of the heart to the test load with a given lv geometry [10].diastolic properties of lv were studied using the study of transmitral diastolic flow (tmdf) by determining the maximum tmdf velocity during early lv filling (ve, m/s), the maximum tmdf velocity during late lv filling (vа, m/s), the ratio of maximum velocities flows in the period of early and late filling (e/a), time of isovolumic relaxation of the left ventricle (tir, ms). the content of crp (vector-best, russia) and proinflammatory cytokines: tnfα and il-6 (protein contour, st. petersburg) were determined in the blood serum of patients by enzyme immunoassay using appropriate test systems. when examining a group of healthy people, the average levels of il-6 (7.27 ± 0.42 pg/ml) and tnf-α (4.62 ± 0.19 pg/ml) were determined. data analysis was carried out using parametric and nonparametric statistical methods. after a preliminary analysis of the distribution of the studied features for normality, the mean value (m) and standard error (m) were calculated. the significance of the differences between the compared parameters was calculated using the method of variation statistics according to student's t-test. the difference between the compared indicators was taken as reliability p < 0.05. to identify correlations between the differences and the parameters, a calculation was carried out using the pearson squares method. the correlation between the estimated parameters was considered reliability at p < 0.05. results and discussion all patients were divided into 2 groups depending on the severity of left ventricular remodeling according to echocardiography, according to ossn criteria (2010). group 1 included 67 (69%) patients with adaptive lv remodeling (stages i–iia), group 2 included 29 (31%) patients with incompatible lv remodeling (stage iib). during the observation period, 6 (6.25%) adverse cardiovascular events occurred. 2 patients of group 1 and 4 patients of group 2 died. the cause of death of one patient from group 1 was complex arrhythmias, the other complications of myocardial infarction. in group 2, the cause of death was progressive heart failure. from the presented data, it can be seen that patients with maladaptive remodeling had significantly more severe manifestations of chf: a higher fc of circulatory failure and a more significant decrease in exercise tolerance. it was also noted that the development of chf is accompanied by a change primarily in the geometry of the lv and an increase in the mass of the lv myocardium. as chf progressed, an increase in the linear dimensions of the lv cavity was observed. in patients with the development of maladaptive remodeling, there was a decrease in the relative lv wall thickness index, which indicates the development of eccentric hypertrophy of lv and the progression of maladaptive remodeling lv , the severity of which increases with the increase in chf fc. in patients with adaptive lv remodeling, concentric hypertrophy of lv prevailed (77%), and in 23% of cases in this group of patients, the development of eccentric hypertrophy of lv was noted. in the study of diastolic function, it was found that the 1st type of diastolic dysfunction american journal of applied science and technology 30 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) prevailed in patients with adaptive lv remodeling, and the 2nd type prevailed in patients with maladaptive lv remodeling. changes in the levels of the studied cytokines in the blood serum and the concentration of crp in patients with chf were characterized by their significant increase with the progression of chf (table 1). the maximum level of cytokines (tnf-α and il-6) was found in patients with maladaptive left ventricular remodeling. in patients with adaptive lv remodeling, there was also an increase in the level of tnf-α in blood serum, but it was insignificant compared to the group of healthy individuals. there was no significant difference in the level of il-6 with the group of healthy subjects. the level of crp in the blood serum before treatment was increased both in group 1 and in group 2, and amounted to 25.99 ± 16.3 and 43.41 ± 11.19 mg/l, respectively, which is significantly higher than normal values. table 1. dynamics of inflammation markers and laboratory parameters before and after treatment with rosuvastatin note ldl low density lipoproteins; tag, triacyglycerides; significant difference (p < 0.05) from pretreatment scores; ** significant difference (p < 0.05) from the same indicator in group 1. we have established a relationship between the levels of pro-inflammatory cytokines in the blood serum and the morpho-functional parameters of the left ventricle. in the group of patients with maladaptive remodeling, a correlation between tnf-α and myocardial mass was noted (r = 0.65; p < 0.05); ms (r = 0.63; p < 0.05); with the state of diastolic function: peak e and e/a (r = 0.72; p < 0.05, r = 0.58; p < 0.05). there was no connection with ef, but there was a correlation with the ef/ms index, which characterizes the specific contractility of the myocardium (r = 0.46; p < 0.05). in patients with adaptive lv remodeling, il-6 correlated with ms (r = 0.39; p < 0.05) and lv wall thickness (r = 0.75; p < 0.05), while tnf-α correlated with ldl (r = 0.41; p < 0.05) and tag (r = 0.38; p < 0.05). thereafter, the results of this study demonstrated that the levels of proinflammatory cytokines in the serum of patients with chf are associated with the development and severity of clinical manifestations of chf. a previously undescribed abrupt increase in serum proinflammatory cytokines was found in patients with maladaptive lv remodeling. against the background of taking rosuvastatin at a daily dose of 20 mg, a positive trend in the clinical manifestations of chf was noted, which was characterized by a significant decrease in the fc of chf and an increase in exercise tolerance according to the test with a 6-minute walk in both group 1 and group 2. there was a significant decrease in myocardial mass, and a decrease in fdv and fsv. an improvement in myocardial contractility was noted, and the ef/ms index increased by 14.2 and 36.0% in patients with adaptive and maladaptive remodeling, respectively. a positive change in the structural and functional state of the left ventricle was accompanied by an improvement in the diastolic function of the left ventricle in the form of a positive change in the structure of diastolic filling (e/a) in both groups. after 12 weeks of the study, in patients with both adaptive and maladaptive lv remodeling, against the background of clinical improvement, a significant decrease in the concentration of crp and proinflammatory cytokines (il-6, tnf-α) in the blood serum was noted. all patients at the time of inclusion in the study according to the score scale for assessing the risk of death from cardiovascular diseases were in the high and very high-risk group. in 62% of patients, after 3 months from the start of treatment with rosuvastatin at a daily dose of 20 mg, the target ldl level (< 2.5 mmol / l) was achieved. our data are largely consistent with the literature data on the adverse effect of proinflammatory cytokines on the initiation, becoming and progression of lv ischemic dysfunction [8]. they also indicate a close relationship american journal of applied science and technology 31 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) between the processes of lv remodeling in chf and the mechanisms of the immune response, which is activated in this disease. the detected significant abrupt increase in the levels of pro-inflammatory cytokines and crp during the development of the maladaptive phase of heart remodeling can serve as a criterion for the severity of chf and become the starting point in the clinician's reasoning about the intensity (aggressiveness) of the therapeutic effect. the results of our study showed that rosuvastatin therapy is not only accompanied by a hypolipidemic effect, but also leads to a significant decrease in the concentration of pro-inflammatory cytokines in the blood serum and crp in patients with chf of ischemic etiology. in our study, the level of crp significantly decreased during treatment with rosuvastatin in both groups, which indicates a decrease in inflammation and is associated with a decrease in cardiac decompensation and, accordingly, the risk of an unfavorable course. this is consistent with the results of a number of studies, which also noted a correlation between the level of proinflammatory cytokines and the severity of clinical manifestations of chf, a decrease in life expectancy, and a decrease in their concentration during treatment is associated with clinical improvement [2]. thus, after 12 weeks, most patients reached the target level of blood lipids, but even more important to us is the pronounced effect of this treatment on the level of pro-inflammatory cytokines and crp, which may contribute to the inhibition of the development of the disease. conclusion 1. the development of the maladaptive phase of lv remodeling is accompanied by a sharp rising the level of pro-inflammatory cytokines and crp in the blood serum. 2. there is a significant correlation of pro inflammatory cytokines with structural and functional changes in the heart in chf. 3. treatment with rosuvastatin (mertenil drug) at a dose of 20 mg in patients with chf of ischemic etiology is accompanied by a decrease in the level of pro-inflammatory cytokines (tnf-α, il-6), serum crp and an improvement in the structural and functional state of the lv in patients with chf of ischemic etiology. references berezikova ye.n., shilova s.n., yefremov a.v. i dr. rol' tsitokinovoy agressii v razvitii khronicheskoy serdechnoy nedostatochnosti // kubanskiy nauchnyy meditsinskiy vestnik. – 2011. – t. 127. № 4. – s. 29–31.

accepted: 20 march 2025; published: 23 april 2025 abstract: one of the most prevalent gastrointestinal disorders is duodenal ulcers. approximately 5–10% of people worldwide will at some point in their lives suffer with this illness. there are two to three times as many males as females. between the ages of 30 and 50, more develops. disease rates are high in industrialized nations like uzbekistan, the us, and europe. although the illness is very uncommon in asia and africa, helicobacter pylori infections are quite common in places with inadequate sanitation. ninety-five percent of cases are caused by helicobacter pylori infection. fast food that is hot, salty, and greasy causes malnutrition. nervousness and psychological aspects. bidens and achillea are used to treat duodenal ulcers. when it comes to gastrointestinal disorders, the herbs bidens and achillea are said to be quite beneficial. they have antibacterial, anti-inflammatory, and wound-finishing properties. a solution containing 14.286 mg/l of each vitamin was created after the first 200 µl of b1, b6, b3, b12, and pp were removed. this led to the creation of standard solutions with 7.143, 3.571, and 1.786 mg/l. standard vitamin c solutions with concentrations of 286, 143, 71.5, and 57.2 mg/l were also prepared. pure water with a concentration of 0 mg/l was used to construct a calibration graph. keywords: gastrointestinal disorders, helicobacter pylori infections. introduction: in uzbekistan, duodenal ulcers are among the most prevalent gastrointestinal conditions. approximately 5% of people have this illness[10]. the condition is more prevalent in people between the ages of 20 and 40. it is five to six times more common in men than in women. risk factors: an poor diet that is inconsistent might cause the condition to develop. the development of the condition is influenced by stress and psychoemotional elements, including mental weariness and both acute and chronic mental events. there are certain distinct symptoms associated with duodenal ulcer illness, even if they are similar to those of stomach ulcers[13]. these are its primary symptoms: pain in the upper abdomen, just above the navel, is the most common symptom. "hunger pains" are made worse by prolonged fasting or starvation [4,8]. after eating, it feels better. it may show up early in the morning or at night. due to the overproduction of gastric juice, boiling the crust (increased acidity) would result in a bitter aftertaste behind the chest. it frequently happens after hot and fatty meals. collection of gas and stomach bloating. abdominal swelling and pain following a meal. flatulence, or gas buildup, is seen as a result of the intestinal system's malfunction[9]. some people experience nausea after eating. in extreme situations, excessive production of stomach juice results in vomiting. some individuals experience an increase in appetite; they eat more to quell "hunger pains." conversely, in some, weight loss and a reduction in appetite are seen. constipation or constipation due to poor intestinal function might be noted. severe consequences, such as bleeding or a deeper cut. vomiting that is dark or crimson (stomach

feces) [5]. acute, stabbing pain is a sign of a perforation, or puncture of the wound. emergency medical attention is required if the patient goes into a condition of shock! it is advised to consult a physician if the illness is exhibiting symptoms! maintaining a healthy lifestyle and safeguarding the gastrointestinal tract are crucial in preventing duodenal ulcers. the following actions lower the chance of contracting the illness: a well-organized diet: eating at the same time each day will stop the stomach from producing too much liquid. consuming meals that are easy to digest, such as milk and dairy products (if not tolerated). steamed veggies and meat. cereal-topped porridge (oatmeal, buckwheat). avoid meals that are fried, salty, spicy, or very hot or cold[11]. avoidance of strong coffee, alcohol, and carbonated beverages. the stomach lining can be harmed by ongoing stress, thus relaxation and following a sleep schedule (sleep for at least 7-8 hours) are important. increasing physical activity (mild walking, sports), practicing yoga, meditation, or breathing techniques. defense against infection with helicobacter pylori. hand washing before to eating. consuming only wholesome, properly prepared meals. adherence to personal hygiene regulations. using caution when taking medicine. avoiding long-term use of medications that might harm the stomach, such as aspirin, ibuprofen, and nonsteroidal anti-inflammatory medicines, unless prescribed by a physician. it is advised to take these medications with stomach protectors if they must be taken. getting rid of negative habits. smoking tobacco and consuming alcohol damage the gastric mucosa and increase the risk of developing a wound. doctor examination. regular visits to the doctor if you have digestive problems or chronic gastritis. check for helicobacter pylori bacteria if necessary. duodenal ulcer with medicinal herbs davolash.an in traditional medicine, various medicinal plants are used to treat duodenal ulcers [15]. these plants help protect the gastric mucosa, reduce inflammation, and repair damaged tissue. the best plants and ways to use them are listed below: bidens's effects include covering the stomach mucosa, protecting it, and lowering inflammation. it has an anti-inflammatory action, heals wounds fast, and repairs the stomach mucosa. one glass of boiling water must be used to soak one spoonful of bidens baggi and rose, and the mixture must be allowed to brew for ten to fifteen minutes. it is advised to consume it on an empty stomach each morning. . course: two to three weeks. dalachoy (hypericum perforatum). effect: preserves the mucous membrane, balances the acidic environment of stomach juice, and speeds up wound healing. it reduces inflammation and has a relaxing impact on spasms. use instructions: infuse one glass of boiling water with one spoonful of dried dalachoy for half an hour. drinking one-third cup before meals two to three times a day is advised. other advice: before consuming therapeutic herbs, a doctor should be contacted. it's critical to maintain a balanced diet and stay away from fried, spicy, and salty meals. stress should be avoided, and restful sleep should be prioritized. these natural and efficient techniques are utilized as adjuvant therapy in conjunction with prescription drugs[3,13]. bidens and achilleaare used to treat duodenal ulcers. when it comes to gastrointestinal disorders, the herbs bidens and achillea are said to be quite beneficial. they have antibacterial, anti-inflammatory, and wound-finishing properties. bidens's beneficial qualities include restoring the stomach juice's equilibrium. lessens inflammation. for half an hour, soak one teaspoon of dried bidens in one cup of hot water. two to three times a day, half a glass should be consumed before meals. the beneficial qualities of achillea(tysjachelistnik, achillea millefolium) include its antibacterial and anti-inflammatory effects. restores and protects the stomach mucosa. regulates the overproduction of gastric juice. infuse 1 cup of hot water with 1 tablespoon of dried achilleafor 20 minutes. two to three times a day, half a glass should be consumed before meals. a blend of achilleaand bidens. when combined, these herbs have a more potent effect on the digestive tract. soak one teaspoon each of achilleaand bidens in one cup of hot water, then let it sit for half an hour [2]. two to three times a day, you can have half a glass before meals. before using these plants over an extended period of time, it is advised to speak with a physician. care should be used when using bidens in people who have low stomach acid. it is not advised for youngsters or pregnant women to consume these plants. duodenal ulcers can also be treated with the use of natural healing agents like achilleaand bidens. assessment of the extract's water-soluble vitamin content using the yussch method experience section. used equipment and a jet. rhydburg

this study investigates the biochemical changes in the saliva of rats under dysbiosis induced by antibiotics. a comparative analysis of the control and experimental groups revealed significant alterations in the levels of albumin, immunoglobulin iga, electrolytes, and organic acids. the results indicate that dysbiosis leads to an increase in the levels of albumin and electrolytes, as well as a decrease in immunoglobulin iga, suggesting potential impairments in immune response and metabolism. the findings underscore the importance of maintaining normal microbiota for health and may

volume 04 issue 09 pages: 54-57 oclc – 1121105677 publisher: oscar publishing services servi dysbacteriosis is a condition characterized by a disruption of the normal ratio of microorganisms in the body, which can lead to various physiological disorders. this condition is most often associated with a change in the composition of the intestinal microflora, which negatively affects metabolism and immune function. saliva plays an important role in the processes of digestion and protection of the body, as it contains enzymes, antibodies and other components responsible for maintaining homeostasis. studying biochemical changes in the composition of saliva in rats with dysbacteriosis can provide important data on the mechanisms underlying this condition, as well as its impact on the overall health of animals. purpose of the study the aim of this study is to investigate the biochemical changes in the saliva composition of rats with antibiotic-induced dysbacteriosis. the study aims to identify changes in the levels of key salivary components such as albumin, immunoglobulin iga , electrolytes and organic acids, and to understand the impact of dysbacteriosis on physiological functions of the body. methods wistar rats were used for the experiment, divided into two groups: control and experimental. the experimental group received ampicillin for two weeks, which led to the suppression of normal microflora. saliva was collected using a non-invasive method based on stimulation of salivation. spectrophotometry and chromatography were used for analysis, allowing the concentration of proteins, electrolytes and organic acids to be determined. results and discussion the results of the study showed significant changes in the biochemical composition of the saliva of rats with dysbacteriosis. 1. changes in protein levels: albumin concentration increased by 30% in the experimental group compared to the control. this may indicate inflammatory processes and the body's systemic response to microbiota disruption. the level of immunoglobulin iga decreased by 40%, indicating a decrease in the local immune response and potential vulnerability to infections. 2. electrolyte composition: sodium and potassium levels increased by 25% in the experimental group, which may reflect changes in water and electrolyte balance. calcium levels decreased by 15%, which may be associated with metabolic and intestinal dysfunction. 3. organic acids: lactate levels increased by 20%, which may indicate metabolic changes and increased glycolysis under stress conditions. these changes in saliva composition may have a significant impact on digestion and the body's defenses. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

140 175 +25% potassium ( mm ) 4.5 5.6 +25% calcium ( mm ) 2.5 2.1 -15% lactate ( mm ) 1.2 1.4 +20% the obtained results show that dysbacteriosis causes significant biochemical changes in the composition of rat saliva. increased levels of albumin and electrolytes may be associated with activation of inflammatory systems and stress reactions. a decrease in iga indicates a weakening of the local immune response, which may increase the risks of infectious diseases and aggravate the consequences of dysbacteriosis. it is also worth noting that changes in the level of organic acids, such as lactate, may indicate a metabolic disorder associated with changes in the microbiota. lactate is a product of anaerobic metabolism and can accumulate under conditions of hypoxia or other metabolic disorders. it should also be mentioned that saliva has many functions, including participation in the initial stages of digestion, protection of teeth and mucous membranes, and participation in the immune response. changes in the composition of saliva may indicate the need for the body to adapt to new conditions and may be important markers of the health of animals. conclusion the study revealed significant biochemical changes in the composition of rat saliva during dysbacteriosis. these changes emphasize the importance of normal microflora for maintaining health and homeostasis of the body.

university of uzbekistan, faculty of biology, tashkent, 61010333, uzbekistan received: 13 january 2025; accepted: 15 february 2025; published: 17 march 2025 abstract: this article is dedicated to an in-depth study of the effect of temperature on the species spermophilus pygmaeus in the field of rodentology. existing studies show that temperature has a great influence on the number of small ground squirrels, their life activity, nest drying, and the development of young ground squirrels. this requires better study of the species and demonstration of new approaches based on ecological research. in studies conducted in the southern regions of uzbekistan in 2023, a systematic analysis was conducted of how the nests, colonies, and population dynamics of these species changed depending on the temperature. to support scientific achievements in the field of rodents, it is necessary to develop new methods and test them in practice. moreover, these studies demonstrate the importance of preserving the biodiversity of rodents and ensuring the sustainability of ecosystems. keywords: spermophilus pygmaeus, rodent, burrow, ethology of the species, synanthropus, landscape, temperature. introduction: today, the animal world is being widely studied, in particular, the distribution of rodents of the genus rodentia, their life activity, role in nature and human life, and the role of representatives of the genus as carriers of infectious diseases. these works require a broader theoretical and practical study of representatives of the genus and are of great practical importance. the occupation of new territories by species and the emergence of new adaptive adaptations to changes in nature are increasing. the migration of rodents for food and habitat is increasing as a result of anthropogenic impact. this situation leads to the fact that species cause more epidemiological situations. that is, the migration of rodents and their approach to residential areas, their ectoparasites, which are carriers of infectious diseases, is accompanied by an increase in the number of various infectious diseases in humans. in addition, the calculation of indicators of the density and annual activity of rodent species is of great importance, and when calculating these indicators, relative indicators are often used, but these indicators do not give a clear picture of their actual number and state. in the scientific works of varshavskiy and kalabukhov, data are presented on the seasonal changes in the life activity of rodents, various adaptations, and seasonal changes in the number of species [1;2;3;4]. the relationship between the annual number of rodents, the spread of various diseases, and the periods of activity of the species is presented in rall's works [8;9]. optimization of conditions for rodents, that is, an increase in temperature, influences the intensification of various chemical reactions and life activity. however, if heat exchange is deviated from the optimal norm, the main factor can become the ambient temperature, which directly affects the ethological, ecological, physiological, and even biochemical reactions of rodents [5;6;7]. the rise in temperature is a factor that determines the food of rodents, their reproduction, the expansion of the range of species, the number and viability of young individuals. temperature also affects how rodents build shelters and construct nests. the increase or decrease in ambient temperature also affects the temperature of the rodent's nest. heat also affects the body temperature of small ground squirrels, the development of their physical thermoregulation, https://doi.org/10.37547/ajbspi/volume05issue03-04 https://doi.org/10.37547/ajbspi/volume05issue03-04

american journal of applied science and technology (issn: 2771-2745) and the conditioned reflex mechanisms of heat regulation [10]. in some rodents, when the ambient temperature changes by 25° (5 30°), the body temperature changes by 0.6-1.2° [11]. in rodents distributed in mountainous areas, changes in ambient temperature contribute to an increase of an average of 0.8° [12]. at the beginning of spring, the body temperature of newborn rodents differs by 1°, while in summer-born rodents it differs by 0.3° from the ambient temperature [13]. we also focused our research on such issues as the influence of ambient temperature on small ground squirrels and the change in the number of species depending on temperature. methods in april 2023, special observations were conducted to determine the number of small ground squirrels (spermophilus pygmaeus) distributed in the natural and cultural landscapes of the nishon district of kashkadarya region, which is considered the southern territory of uzbekistan. a total of 532 small ground squirrels were caught using various traps between 10:00-14:00 in the warmest part of the day and between 18:00-20:00 in the second part of the day. 50 traps were used to catch small ground squirrels. thermometers were used to measure the temperature. results and discussion our research is also aimed at studying the vital activity of representatives of the genus rodentia in the southern regions of uzbekistan, their numbers, the influence of seasonal changes, and migration to agricultural lands. the research work examined the temperature-dependent changes in the number of small ground squirrels (spermophilus pygmaeus) distributed in the natural and cultural landscapes of the nishan district of kashkadarya region, which is considered the southern territory of uzbekistan. the awakening of spermophilus pygmaeus from winter sleep occurs at the beginning of hot days, that is, in the middle of march. in the southern regions of uzbekistan, spring comes early, and the temperature begins to rise from the beginning of march. in spring, an increase in the temperature leads to an increase in the intensity of movement of small ground squirrels. in the evening and at night, in any season of the year, the activity of small ground squirrels is practically zero. nevertheless, the level of animal activity does not directly affect their actual population. table 1. number of spermophilus pygmaeus in the study area in relation to temperature. day time 10:00-14:00 time 18:00-20:00 temperature number of species temperature number of

temperature was 21°c. the condition of the traps and the presence of rodents in them were monitored hourly. by the second half of the day, from 18:00 to 20:00, traps were placed again, and 3 small ground squirrels were caught, during which the temperature was 15°c. the same work was repeated for 5 days, and the data presented in table 1 were obtained. on april 20, 50 traps were placed in the study area, and 29 small ground squirrels were caught, and when checking the temperature, it was found that it rose to 23°c. in the second half of the day, the temperature reached 17°c, and 5 small ground squirrels were caught in traps. on may 1, between 10:00 and 14:00, 37 small ground squirrels were caught at 28°c, 43 on may 10 at 30°c, and 40 on may 26 at 29°c, 11 on may 1 at 20°c, 19 on may 10 at 21°c, and 40 on may 26 at 17°c. the average temperature between april 9 and may 26 was 22.5°c. traps were set daily and checked twice during the specified time interval. a total of 225 small ground squirrels were caught between the days of the experiment, and depending on the temperature, 62 ground squirrels were caught on the 3rd day of the experiment (may 10), which is the highest indicator. on the 1st day (april 9), 24 small ground squirrels were caught, which is the american journal of applied science and technology 17 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) smallest number. from the above data and the number of rodents caught, it can be said that the most active period of small ground squirrels occurs during hot periods of the day. on hot summer days, small ground squirrels become less active with sunset. thus, depending on environmental conditions, mainly the temperature factor, small ground squirrels increase or decrease their activity. increasing the temperature increases the activity of small ground squirrels. a significant increase in the number of ground squirrels was observed when the ambient temperature changed from 21°c to 30°c. this increase in activity occurs due to the following reasons: increased metabolic rate in ground squirrels, metabolism accelerates with higher temperatures, which increases their likelihood of faster digestion and searching for more food. increased activity a rise in temperature in small ground squirrels increases their physical activity and begins to actively respond to external stimuli. conclusion based on the above data, it can be concluded that if relative methods are used to calculate the number of rodents (for example, using traps), the obtained data will reflect not the number of animals, but their dynamic density. the increase in temperature increases the activity of small ground squirrels, accelerating the processes of searching for food and feeding. on the other hand, a decrease in temperature, especially in the evening and morning, reduces their activity. this can probably be shown as an adaptive reaction of small ground squirrels to temperature changes. with a decrease in temperature, the number of ground squirrels outside the nest decreased significantly. at low temperatures in the evening, their activity decreases, and we characterized this by the following. with the cooling of the air in the evening and at night, organisms quickly lose heat. therefore, their activity level decreases. on april 9 (21°c) and april 20 (23°c), the number of small ground squirrels reached 21 and 29 individuals. this change was observed due to the increase in temperature. on may 1 (28°c) and may 10 (30°c), the number of ground squirrels increased to 37 and 43 units. temperature sensitivity helps organisms adapt to environmental conditions. small ground squirrels undoubtedly have the ability to adapt to environmental conditions, such as changes in temperature, food sources, and the search for shelter. at low temperatures, their activity decreases and they hide more or spend time in shelters. low temperatures also affect the development of the younger generation. temperature changes also affect the mites' reaction to the environment and their adaptation to their habitat. there are four ecological factors necessary for the life of warm-blooded animals, including rodents. temperature comes first. all life processes associated with temperature are important for any living organism. the temperature factor is especially important for rodents, as their small size leads to high heat loss. in conditions close to optimal conditions, the temperature factor may not be involved in determining the specific reactions of animals. however, if heat exchange deviates from the optimal norm, the ambient temperature can become the main factor, which directly affects the ethological, ecological, physiological, and even biochemical reactions of rodents. references varshavskiy s. n. laws of seasonal movements of muscular grizzlies. zoologist, journal, vol. xvi, issue. 2, 1937.

specialists, especially surgeons, radiologists, neurologists and other specialists involved in the diagnosis and treatment of diseases associated with the complex anatomical structure of the body. traditional teaching methods anatomical atlases, curvilinear models and laboratory practices have their limitations related to volume, accessibility and visualization capabilities. in modern medicine, the use of three-dimensional modeling technologies (3d modeling) is becoming increasingly popular, which allow creating accurate, interactive and easily accessible educational materials. in this article, we will consider the advantages, modern practices and prospects for the introduction of 3d modeling in the teaching of topographic anatomy. 1. relevance of using 3d modeling in medical education medical knowledge requires constant updating and deepening. topographic anatomy is a section that involves understanding the spatial relationships of various body structures. traditionally, its teaching was based on the use of two-dimensional images, even in the presence of 3d atlases. however, such methods often do not sufficiently reflect the complex spatial orientation of structures. with the development of 3d technologies, the possibilities have expanded significantly: interactive learning the student can independently rotate models, zoom in and out, get different angles. three-dimensional perception modeling allows you to better understand the location of blood vessels, nerves, muscles, bones. accessibility online platforms allow you to study at any time and from anywhere in the world. according to research, the use of 3d models improves memorability and the quality of assimilation of material, reduces errors in practical activities (zhang et al., 2021). 2. modern 3d modeling technologies and their implementation in education there are several technologies and tools used to create and apply 3d models: data sources: mainly computed tomography (ct), magnetic resonance imaging (mri) and anatomical scans, which allow obtaining very accurate digital 3d images. software: platforms such as 3dslicer, osirix, blender, unity remain popular for creating interactive models. virtual and augmented reality (vr and ar): devices such as oculus rift, htc vive or microsoft hololens allow for interactive learning in virtual spaces and modeling spatial relationships of structures. these technologies create immersive environments https://doi.org/10.37547/ajbspi/volume05issue05-03 https://doi.org/10.37547/ajbspi/volume05issue05-03 american journal of applied science and technology 9 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) where the student can “immerse” himself in the interior of the human body and study its anatomical features. 3. benefits of using 3d modeling in teaching topographic anatomy using 3d technology offers a number of benefits: 3.1 improved understanding of spatial relationships 3d models convey complex relationships between structures, which is especially important in areas where the precise location of vessels, nerve trunks and bones is critical. 3.2 increased student motivation interactive platforms make learning more interesting and engaging, stimulating independent learning. 3.3 possibility of repeated learning of material students can practice without the time and expense of physical models and bone casts. 3.4 facilitation of distance learning the global transition to distance learning due to the coronavirus pandemic has shown the need to use online resources such as vr platforms and 3d tools. 3.5 improved clinical skills planning surgeries, simulating surgical interventions and training in surgical incision skills are possible thanks to accurate virtual models. 4. examples of 3d modeling application in topographic anatomy 4.1 head and neck anatomy training creating detailed models of blood vessels, nerve trunks, muscles and bones of the head helps in training otolaryngologists, neurosurgeons and dentists. 4.2 chest and abdominal anatomy training models allow dynamic study of the location of the heart, lungs, large vessels, digestive organs, as well as vascular pathologies. 4.3 surgical intervention planning before operations, doctors use virtual models to simulate and select optimal approaches, which reduces risks. 5. prospects and challenges of implementing 3d technologies despite the obvious advantages, there are also difficulties associated with implementation: cost of technology development and implementation — creating highly accurate models requires significant investment. teacher training — advanced training courses are needed to work with new platforms. content standardization — creating generally accepted methods and programs. integration into the curriculum – curriculums need to be adapted to accommodate these technologies. however, advances in artificial intelligence and computer-aided modeling promise to reduce these barriers and make 3d technology more accessible. conclusion. the use of 3d modeling in teaching topographic anatomy is a promising direction that significantly improves the quality and efficiency of training medical specialists. modern technologies allow not only to better understand complex anatomical structures, but also to prepare for real clinical situations, which contributes to increased patient safety and improved treatment outcomes. the implementation of such methods requires joint efforts of teachers, technologists and clinicians, but their potential justifies the costs and efforts. references асмоловский а. в., шаматкова с. в. особенности преподавания оперативной хирургии и топографической анатомии на современном этапе //вестник

role in the body of mammals, participating in the processes of digestion, moistening the oral cavity and protection from pathogenic microorganisms. the parotid salivary glands, in particular, are one of the largest paired glands that secrete a secretion containing enzymes, amylose and other substances necessary for digestion of food. these glands, like other exocrine organs, undergo a complex process of morphological and functional development during ontogenesis, which is important for understanding not only their normal function, but also the pathology associated with disturbances in their development. in rabbits, as one of the common objects of zoological research, the parotid salivary glands play an important role in digestion, and their morphological development in the postnatal period is of particular interest for studying the mechanism of formation and differentiation of glandular tissues. however, despite the importance of these studies, issues related to the morphogenesis of the parotid salivary glands in rabbits in postnatal ontogenesis remain insufficiently covered in the scientific literature. the present study is aimed at studying the morphological features of the development of the parotid salivary glands in rabbits in the postnatal period. the main attention is paid to the various stages of their development, as well as the analysis of morphofunctional changes during growth and formation. the data obtained can serve as a basis for further research in both normal physiology and pathology of the salivary glands, which, in turn, is important for veterinary medicine and biology. the purpose of the study the aim of this study is to analyze the stages of morphological development of the parotid salivary glands in rabbits during postnatal ontogenesis, with an emphasis on the key stages of cell differentiation, the development of gland structures and their morphofunctional changes at different age stages. methods the study involved the use of rabbit carcasses of various age groups, from newborns to adults. the animals were obtained from a laboratory nursery and were used in accordance with the ethical standards for scientific research. morphological examination of the parotid salivary glands was performed using histological methods. for this purpose, tissue samples were selected, fixed in 10%

sections 5-7 μm thick were stained with hematoxylin and eosin to assess the general morphology of the glands, as well as using special methods (for example, staining according to the verhoeff method) to highlight the structural features of the cells and ducts. to evaluate the morphometric parameters, a light microscope imaging technique was used with a digital camera and appropriate software. cell sizes, duct wall thicknesses, cell density in different areas of the glands were measured, and changes in tissue structure were analyzed depending on the age of the animals. in addition, to identify functional changes in the structure of the salivary glands, immunohistochemical analysis was performed using antibodies to specific markers of cells involved in the production of saliva. results and discussion morphological examination of the parotid salivary glands showed that with age, rabbits experience significant development of the structure of these glands. in newborn animals, the glands were less differentiated, with insufficiently developed ducts and an insignificant number of secretory cells. while in adult rabbits, clear differentiation of cells, developed ducts and pronounced secretory activity are observed. the use of hematoxylin and eosin made it possible to isolate mature acinar cells in older individuals, indicating the development of functional maturity of the glands. while in newborns, immature cells with less pronounced secretory activity predominated. morphometric analysis showed that the size of the cells and the thickness of the duct walls increase with age. in newborn rabbits, the cells of the parotid glands were significantly smaller in size, and the walls of the ducts were thinner. while in adult animals, the cell sizes increased and the duct walls thickened, indicating an increase in the functional activity of the glands. the cell density also increased with age, which may be due to the intensity of saliva secretion and the adaptation of the glands to a more active function. immunohistochemical analysis using antibodies to markers of cells involved in saliva production (e.g., amylose and acid mucoprotein) showed that in adult rabbits the expression level of these markers was significantly higher than in neonates. this confirms the hypothesis that with age, the activity of the salivary glands and their ability to produce saliva increases. in newborn individuals, markers of saliva production were poorly expressed, which may be associated with insufficient maturity of the salivary glands at this age. conclusion the obtained data indicate that the parotid salivary glands of rabbits undergo significant changes during the process of growth and development. from newborn to adult individuals, both morphological and functional changes occur, which correlate with the age and level of development of the animal. the increase in cell size and thickening of the duct walls is associated with an increase in the functional activity of the glands, which may be due to the body's need for https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume

serve as a basis for further research aimed at studying changes in the salivary glands in other animal species or humans, as well as for developing methods to improve the functioning of the salivary

education, one of the important tasks is to develop students' independent and critical thinking skills. medical science requires an understanding of complex biological processes, which cannot be fully achieved by traditional teaching methods. therefore, technologies for modeling biological problems are being introduced into the educational process. this article analyzes the impact of modeling technologies on the development of critical thinking in medical education. medical education is the process of training qualified specialists for the healthcare sector, which includes teaching the basics of medical science, developing clinical skills, and increasing practical experience. the main goal of medical education is to train highly qualified doctors, nurses, and other medical specialists to provide quality medical services to society. important aspects of medical education: interdisciplinary approach related to biology, chemistry, physics, pharmacology, anatomy, and other sciences. practical training simulation laboratories, hospital practices. innovative technologies use of simulations, virtual reality, artificial intelligence and medical modeling. critical and

technologies. mathematical models represent physiological and biochemical processes of the organism; computer simulations predict the organism's response to various situations. virtual laboratories are a way to express the possibility of conducting experiments in safe conditions, allowing for a deeper understanding of complex biological processes. modeling of biological processes in medicine is used in the following areas. the role of critical thinking in the development of critical thinking critical thinking is a special type of thinking that draws conclusions by analyzing facts. it is the ability to analyze problems, draw conclusions based on evidence, and evaluate alternative solutions. modeling biological problems develops students' critical thinking through the following aspects. this concept has complex and diverse definitions, including rationality, skepticism, objective analysis, and fact-checking. its prerequisite is to agree to strict standards of mental development and apply them with vigilance. critical thinking requires the acquisition of effective communication and problemsolving skills, as well as overcoming our natural egocentrism and sociocentrism. visualizing complex biological processes by creating models of processes occurring in the body, students understand their dynamics and have the opportunity to analyze problems in depth. opportunity to experiment by simulating processes that are difficult to implement in real life, students analyze how specific medical conditions develop in different scenarios. development of problem-solving skills through modeling, students develop the skills to study variable data, make assumptions, and test them. teamwork and discussions students have the opportunity to justify their own ideas and analyze the ideas of other group members while working on a specific biological model. advantages of using in medical education biological process modeling technologies have the following advantages: clarity and clarity students consolidate theoretical knowledge using visual and interactive methods; real-time error analysis based on models, students have the opportunity to quickly review their mistakes and correct them; independent formation of ideas students try to solve problems based on their own ideas. in the modern medical education system, it is not enough to provide students with theoretical knowledge alone. it is also important to develop their independent and critical thinking skills. the use of modeling technologies is one of the important tools for analyzing and understanding various complex processes, especially in the field of biological and medical sciences. the essence of biological modeling technologies biological modeling is the process of describing the processes occurring inside an organism using various models (mathematical, computer, graphical, physical) to understand and analyze them. with the help of these technologies, students can gain a deeper understanding of complex biological phenomena and independently formulate their own ideas. the main types of modeling technologies: mathematical models describing the activities of cells and organs using mathematical equations. computer modeling simulating how the organism responds to various diseases. virtual laboratories interactive systems that allow you to conduct experiments in a safe environment. 3d visualization analysis of biological structures in three dimensions. the role in the development of critical thinking critical thinking is the ability to analyze information, draw evidence-based conclusions, and make independent decisions based on existing theories or evidence. modeling biological problems develops critical thinking through the following aspects: deep analysis of complex biological processes students can understand the mechanisms of disease development using various models and isolate important parts of them by visualizing processes. students safely conduct expensive and dangerous experiments in the real world in virtual laboratories and draw conclusions based on their results. study and evaluate alternative solutions modeling technologies encourage students to test different scenarios. for example, the effect of a drug on the body is analyzed using different models, which allows them to compare alternative treatment methods. by working together on specific models, students develop the skills of expressing their opinions, discussing with other group members, and justifying arguments. advantages of modeling technologies in medical education american journal of applied science and technology 35 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) practical application of theoretical knowledge students have the opportunity to apply the theoretical knowledge they have learned to real life. expressing complex information in an understandable form through visualization, students can more easily understand complex processes. real-time error analysis through modeling, students have the opportunity to identify and correct their own errors. developing decision-making and reasoning skills students learn to find the most optimal solution by testing different scenarios. modeling when we talk about medical and biological tasks, we mean understanding the text, finding solutions using mathematical methods. aspects of mathematical education in a medical university can be considered on the basis of a universal multiplicative model of the quality of education. it is necessary to move from classical methods in teaching mathematics to the method of applying mathematical methods in medical practice. the reasons for the low level of students in modeling are: insufficient use of this method; mainly explanatory and illustrative methods are used in the educational process; the conflict between the scientifically based methodology of teaching and existing methods, which does not allow to fully reveal the diversity of the application of the modeling method to the educational process. thus, the current methods of teaching students using the modeling method are not enough to ensure the required level of education and professional skills of graduates. analysis of the state of problems of student learning in medical universities revealed the following contradictions. scientific information in the field of medicine has increased. this information cannot be delivered to students without modeling and other modern methods. between the increasing role of the modeling method in scientific research and education and the existing theoretical research in the field of teaching methods of scientific disciplines, there were no conceptual rules that would allow creating a teaching methodology for students using the modeling method. the requirements for the quality of personnel training are increasing. but the level of training is not significant. the methodological system for training students in modeling has its own characteristics. the unification of natural scientific knowledge within the framework of various scientific disciplines based on the modeling method, i.e. systematic reflection, experimental planning, construction of scientific theories, the educational role of the modeling method in scientific research. the following stages of targeted selection of educational material and training students in the modeling method are the provision of new theoretical materials to familiarize them with the modeling method. development of general approaches to the application of the modeling method. using the natural scientific content of specially developed creative tasks aimed at using the modeling method in the formation of special professional competencies in the process of teaching subjects. the use of this method increases competence in the field of modeling, develops theoretical thinking. the main principles of improving educational technologies using mathematical modeling methods are implemented. a higher educational institution with a medical specialty as its professional direction should provide mathematical training: mastering the mathematical apparatus that allows students to model, analyze and solve important problems related to simple mathematics encountered in medical science and practice; explaining the need to improve knowledge in the field of mathematics and its application. the implementation of the professional direction of teaching mathematics for a given specialty includes: firstly, maintaining mathematics within the framework of a single invariant course; secondly, ensuring the use of mathematics in other disciplines, thirdly, using mathematical models used in various branches of medical science and practice. when choosing a mathematical content for training medical students, the following principles should be followed: a phased approach, personal and professional significance and adaptation. together, these principles allow you to adjust the nature and depth of the studied mathematical material to the mathematical and propaedeutic-professional study. they contribute to the development of methodological support for the mathematical preparation of the future doctor. the mathematical preparation of a doctor should be carried out in the following areas: integrativeness, connection between elementary and senior courses, compatibility of students' future professional elements with mathematical activities, the preparation of professionally oriented tasks is achieved through the use of activities; renewal of professional motivation, which is carried out on the basis of involving situations that are significant from the point of view of medical practice; creative approach to issues. the creation of training materials and systems of professionally oriented tasks in various mathematical sections, as well as topics for practical work, their american journal of applied science and technology 36 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) implementation involves the involvement of a very serious mathematical apparatus. from the point of view of the problems under study, mathematical problems are considered, first of all, as a means of developing professionally important intellectual qualities necessary for a future doctor ("unusual" problems play an important role here), and secondly, as a carrier of mathematical content of professional importance. the formation of skills necessary for the formulation and solution of problems of a medical nature, their components are highlighted, an algorithm of the corresponding work is formulated, various methods of such work are indicated (including the introduction of professional information into the conditions of a mathematical problem; "framing" the condition with a purely medical plot, etc.), and a typology of tasks of this type is presented. when developing methodological support for the mathematical training of a future doctor, it is recommended to adhere to the following basic rules. modeling and modeling classification each model is created for a specific purpose and is therefore unique. however, the presence of common features allows us to group all their diversity into separate classes, which facilitates their development and study. in theory, there are many signs of classification, and their number is not determined. however, the following classification criteria are most suitable: the nature of the simulated side of the object; the nature of the processes occurring in the object; the method of implementing the model. classification and modeling of models based on the "nature of the simulated side of the object". functional models demonstrate only the behavior, the function of the modeled object. in this case, the simulated object is considered a "black box" with inputs and outputs. the physical nature of the object, the nature of the processes occurring in it, the structure of the object, since they are unknown, are ignored by the researcher. in functional modeling, the experiment consists of observing the output of a simulated object with artificial or natural changes in input effects. based on this data, a behavioral model is built in the form of some mathematical functions. a computer chess program is a functional model of the human brain when playing chess. structural modeling is the creation and study of a model whose structure (elements and connections) is similar to the structure of the simulated object. as we learned earlier, the similarity is not established at all, but is established relative to the research goal. therefore, it can be described at different levels of consideration. the most general description of the structure is a topological description using graph theory. for example, military exercises are a structural model of a type of military action. classification of models and modeling based on the "nature of the processes occurring in the object". according to this criterion, models can be deterministic or stochastic, static or dynamic, discrete or continuous or discrete-continuous. deterministic models represent processes that do not have random effects. to develop critical thinking, you need to do the following: step one. first, you need to analyze the information, interpret it, and if necessary, evaluate it. this is the most important competency in working with information. what is primary and secondary information? what is primary and secondary? cause and effect? how is one piece of information related to another? step two. it is very difficult to confuse the thoughts of a critical thinker, because he can easily identify all logical errors and any inconsistencies in thinking. use a simple algorithm of critical questions. is the topic of discussion clear? can all arguments be called true? are all arguments disclosed and proven? are there no contradictions? step three. finding logical errors is one thing, explaining them and substantiating them to your opponent is another. the skill of argumentation and convincing reasoning is the main aspect of critical thinking. persuasion should not be based on a beautiful presentation or form, but on comprehensively proven and disclosed evidence. the fourth step. and finally, the main point. a person can theoretically analyze information perfectly, find logical errors in exercises in a logic textbook, build arguments in the format of an artificial “debate”, but if he cannot apply all this knowledge and skills to business practice and solve real practical cases, this method will not give any results. therefore, the fourth component of critical thinking is the ability to apply the results to solve problems. critical thinking can and is very necessary to develop. it requires constant development. critical thinking is not about criticism. it is about how to navigate in a huge flow of information, how to analyze incoming information. you need to doubt and ask different questions. the more complex the idea, the statement, the more questions you should have. it is important not to be afraid to check the information several times and look for primary sources, compare several sources. most importantly, you need to learn to look at everything critically and not just believe any information. american journal of applied science and technology 37 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) conclusion the use of biological modeling technologies in medical education is an effective tool for teaching students critical thinking. through these technologies, students visually analyze complex biological processes and develop scientific thinking and problem-solving skills. therefore, the widespread introduction of modeling technologies in medical education is of great importance. critical thinking plays an important role for doctors. references атаханов, с., & журабоева, д.

published: 11 february 2025 abstract: in recent years, chronic liver diseases have become a significant cause of death and disability [2], there is a trend towards an increase in the number of patients with chronic liver disease. it is widespread mainly among people of working age [3], which is explained by the living conditions of modern humans and the presence of a large number of chemical compounds in the environment. this leads to changes in metabolic processes in the liver and its toxic damage. according to who data, over the past 20 years, there has been a trend towards an increase in the number of liver diseases leading to high mortality worldwide. today, the number of patients with various hepatobiliary pathologies in the world exceeds 2 billion people. in the cis countries alone, between 500,000 and 1 million people with various liver diseases are registered annually [4]. a sharp increase in the number of patients with chronic liver diseases was facilitated by an increase in the incidence of viral and toxic (alcoholic and drug) hepatitis, as well as a significant increase in the number of patients with obesity and diabetes mellitus. the hepatoprotective properties of drugs improve metabolism, inhibit peroxidation, activate lipid metabolism, and protect mitochondrial and microsomal enzymes from damage to varying degrees [1]. keywords: hepatitis, experimental hepatitis, paracetamol hepatitis, hepatitis induced by 40% ethyl alcohol, galactosamine hepatitis induction model, carbon tetrachloride (ccl4). introduction: today, despite the wide range of preparations with hepatoprotective properties, the demand for this group of preparations remains high. scientific research aimed at solving this problem is based on the correct choice of the hepatitis model and the correct conduct of the experiment. therefore, we began our research with the analysis of models of experimental hepatitis induction. currently, the following methods are used in the study of experimental liver poisoning: 1. citing a model of carbon tetrachloride (ccl4) poisoning in the liver calculating a model of liver poisoning using carbon tetrachloride (ccl4) is a widely used method in toxicological and biomedical research. when creating https://doi.org/10.37547/ajbspi/volume05issue02-02 https://doi.org/10.37547/ajbspi/volume05issue02-02

american journal of applied science and technology (issn: 2771-2745) this model, the following steps are carried out: experiment design for this purpose, groups are created for white male laboratory rats. at least 4 groups are taken, with no less than 6 white male laboratory rats in each. the 1st group is the "intact" group, in which the disease is not caused. the 2nd group is the "control" group, where carbon tetrachloride (ccl4) causes liver poisoning and is not treated. the 3rd group is the experimental group, where carbon tetrachloride (ccl4) causes poisoning in the liver, and before this, the studied drug was administered in a certain dose. the 4th group is the comparison group, where carbon tetrachloride (ccl4) causes poisoning in the liver, and before this, the drug, which is widely used in medical practice today, is administered in a certain dose. experiment these groups were cut 0.5 cm from the tip of the tail of all laboratory rats, blood was taken to obtain preliminary biochemical results, and a preliminary analysis was conducted. after this, the "intakt" group was given distilled water for 6 days, corresponding to body weight. the control group was also given distilled water for 6 days. the experimental group was given the studied drug at 1 mg/kg or at a certain dose for 6 days. the comparison group is given a drug that has been used in medical practice for 6 days. on the 7th day, all groups, except the intact group, were administered 50% carbon tetrachloride (ccl4) 0.3 ml for every 100 g of body weight 3 times a day. blood was taken from the tail of laboratory rats of all groups for biochemical analysis. monitoring and evaluation monitoring for several hours or days after administering the drug. researchers evaluate changes occurring in the liver, blood enzyme levels, and other biological indicators. this process helps to understand the mechanisms of liver poisoning. health metrics observe the general health of rats, in particular their activity and behavior. ` liver function assessment taking blood samples to assess liver function and measuring alt (alanine aminotransferase), ast (aspartate aminotransferase), and bilirubin levels. 2. eliciting a model of liver poisoning in laboratory rats using paracetamol. citing a model of liver poisoning in laboratory rats using paracetamol (acetaminophen) mainly uses the ability of paracetamol to damage liver cells at high doses. this model is widely used for the study of liver diseases and the testing of new treatment methods. below is the process of creating a model of liver poisoning using paracetamol: experiment design for this, 180-220 g of laboratory rats (for example, sprague-dawley or wistar rats) are selected and grouped. for this, at least 4 groups of white male laboratory rats are taken, with no less than 6 in each. the 1st group is the "intact" group, in which the disease is not caused. the 2nd group is the "control" group, where paracetamol causes liver poisoning and is not treated. the 3rd group was the experimental group, where paracetamol induced liver poisoning, and the studied drug was previously administered in a specific dose. the 4th group is the comparison group, where paracetamol causes liver poisoning, and before this, the drug, which is widely used in medical practice today, is administered in a certain dose. experiment before starting the experiments, the rats intended for the experiment are weighed and grouped. blood was taken from all groups of rats and the initial biochemical blood parameters were determined. modeling of liver damage using paracetamol was carried out as follows: laboratory white male rats weighing 180-220 g were given the studied preparation at various doses once a day for 14 days. for the next two days, 1000 mg/kg of paracetamol is administered orally once. the rats of the control group were given distilled water under the same conditions, and they were also injected with paracetamol at 1000 mg/kg for the last 2 days. the intact group is given distilled water under the same conditions. the drug of comparison (placebo or another drug) is also administered for 14 days and paracetamol 1000 mg/kg once a day for the last 2 days. monitoring and evaluation monitoring for several hours or days after administering the drug. on the last day of the experiment, blood was taken from all groups of laboratory rats, biochemical indicators were analyzed, and the results were evaluated by comparison with the initial blood test. health metrics observe the general health of rats, in particular their activity and behavior. american journal of applied science and technology 7 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) liver

model in laboratory rats using 40% ethyl alcohol. with the help of this model, it is possible to study the mechanisms of ethanol leading to liver poisoning and test potential antidotes or treatment methods. experiment design for this purpose, groups are created for white male laboratory rats. at least 4 groups are taken, with no less than 6 white male laboratory rats in each. the 1st group is the "intact" group, in which the disease is not caused. the 2nd group is the "control" group, where poisoning of the liver with 40% ethyl alcohol is induced and is not treated. the 3rd group was the experimental group, where poisoning of the liver was induced with 40% ethyl alcohol, and before this, the studied drug was administered in a certain dose. the 4th group is a comparison group (placebo or another drug), in which poisoning of the liver is induced with the help of 40% ethyl alcohol, and before this, the drug, widely used today in medical practice, is administered in a certain dose. experiment before starting the experiments, the rats intended for the experiment are weighed and grouped. blood was taken from all groups of rats and the initial biochemical blood parameters were determined. modeling of liver damage using paracetamol was carried out as follows: laboratory white male rats weighing 180-220 g were given 40% ethyl alcohol 1 time a day for 7 days, 2 hours before administration, in various doses. on the last 7 days of the experiment, 40% ethyl alcohol is administered orally once for 7 days, 2 hours before administration. the rats of the control group were given distilled water under the same conditions, and on the 7th day, 2 hours after the injection of distilled water, they were also injected with 7 ml/kg of 40% ethyl alcohol using a probe. the intact group is given distilled water under the same conditions. the comparison drug (placebo or another drug) is also administered for 7 days, and 7 ml/kg of 40% ethyl alcohol is administered 2 hours after the last drug was administered. monitoring and evaluation monitoring for several hours or days after administering the drug. on the last day of the experiment, blood was taken from all groups of laboratory rats, biochemical indicators were analyzed, and the results were evaluated in comparison with the initial blood test. health metrics observe the general health of rats, in particular their activities and behavior. liver function assessment taking blood samples to assess liver function and measuring alt (alanine aminotransferase), ast (aspartate aminotransferase), and bilirubin levels. 3. experimental model for inducing galactosamine hepatitis the galactosamine hepatitis induction model is a widely used experimental method for studying liver diseases. with the help of this model, it is possible to study the processes of inflammation and liver damage. this method is closest to viral liver disease (vengerovsky a.i. et al. 1999-2002). below is information about the process of creating a model of galactosamine hepatitis: in this method, the experimental design and analysis methods are almost identical, differing in the method of causing poisoning agent and disease. galactosamine was administered orally to laboratory rats of all groups, except the intact group, at a dose of 500 mg/kg for 4 days. during the experiment, observation of the general health and behavior of the rats, assessment of liver function: taking blood samples and measuring the levels of alt, ast, bilirubin, histological analysis: taking liver tissue, microscopic examination: microscopic examination is carried out to identify changes in liver cells (for example, inflammation, necrosis, fibrosis). the obtained results were subjected to statistical analysis and the influence of galactosamine on liver poisoning was determined. in any experiment, it is important to observe ethical standards. it is necessary to obtain permission from the ethics committee before using animals. conclusion each of the experimental models we studied is of particular importance, and the preparations planned for study should be studied in all four ways. references novikov v.e., klimkina

science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 11 pages: 31-35 oclc – 1121105677 publisher: oscar publishing services servi introduction a large number of studies conducted around the world over the past two years have shown that due to the spread of the new coronavirus infection, the number of diseases of the oral mucosa caused by covid-19 is steadily increasing. coronavirus can cause not only pneumonia, but also affect the mucous membrane of the oral cavity. the pathogenic agent enters the body thanks to angiotensin-converting enzyme 2, which is localized both on the surface of the alveoli and pulmonary structures, and on the epithelial cells of the oral cavity, where it begins to actively multiply. there are publications in the literature that more than 80% of patients who have suffered coronavirus infection note changes in the oral mucosa in the form of dryness and damage to the lips. xerostomia can be caused both by taking medications and by the influence of aggravated systemic diseases. more than 500 medications can cause xerostomia. according to researchers, post-covid syndrome is a fairly broad diagnosis with psychophysiological consequences. a separate code has appeared in icd-10 to describe post-covid syndrome (u09.9). psycho-emotional disturbances (usually in the form of increased personal anxiety, sleep disorders, anger, autonomic disorders, asthenic syndrome with emotional lability), which occurs against the background of the covid-19 pandemic, significantly affect not only the quality of life of patients who have had covid-19, but and is a predictor of disease. in this connection, the dynamics of the occurrence and development of diseases, in the etiology of which the main factor is neurogenic nature, is increasing. such diseases include cheilitis. according to domestic and foreign literature, lip diseases are relatively common and are an important problem in modern dentistry, since their diagnosis poses significant difficulties, and the treatment of this pathology is not always successful. the most common are inflammatory and destructive diseases, such as meteorological, exfoliative, actinic cheilitis and chronic lip fissures. being under the constant influence of external and internal factors, the red border of the lips is the site of manifestation of various diseases, including dermatoses. in addition, the mucous membrane of the red border of the lips can be subject to all sorts of inflammatory processes, undergoing various transformations, which, in turn, leads to significant difficulties in making a diagnosis. exfoliative cheilitis k13.0 is a chronic disease of the red border of the lips, characterized by a complex and not fully understood etiopathogenesis, a variety of trigger factors and the often insufficient effect of the therapy used. exfoliative cheilitis was first described in 1922. by french scientists mikulic and kümmel as “persistent peeling of the lips.” https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 11-2024 33 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 11 pages: 31-35 oclc – 1121105677 publisher: oscar publishing services servi most researchers believe that neurogenic factors underlie the disease. patients suffering from it experience a more or less significant functional disorder of the nervous system. various allergens, both endogenous and exogenous, can also be factors that support and aggravate the disease. in patients with exfoliative cheilitis, various types of psycho-emotional disorders, anxiety reactions, and depressive states have been identified. there is evidence of the possible role of immunological factors in the pathogenesis of the disease. in addition, the presence of dry mucous membranes and a decrease in the amount of saliva affects the development of the disease, since in this case the balance of oral microorganisms is disrupted. patients lick their lips more often, resulting in a red border of the lips cracks and peels. the disease negatively affects the aesthetic qualities of the patient, leading to serious psychological and social disorders due to cosmetic defects. treatment of lip diseases is one of the difficult tasks of modern dentistry. based on an analysis of literature sources by domestic and foreign authors devoted to the study of the condition of the red border of the lips and treatment methods, it can be concluded that existing approaches to the treatment of this pathology are not effective enough. despite advances in pharmacology, the effectiveness of most drugs and treatment methods remains unsatisfactory. currently, there is no single universal approach to the treatment of cheilitis and most existing methods have a temporary positive effect. in addition, post-covid cheilitis is particularly resistant to therapy and has a long course. therefore, it is urgent to search for new methods of treating exfoliative cheilitis that are highly effective with the least possibility of complications.this raises the need for further research to optimize the treatment of lip diseases. at the moment, one of the modern trends is the use of laser technologies. the purpose of the study is to increase the effectiveness of complex treatment of patients with exfoliative cheilitis who have had covid-19 infection by including a diode laser in the treatment regimen. research objectives: 1. to study the effect of a diode laser on reducing the intensity of pain sensitivity in patients with exfoliative cheilitis. 2. to study the effect of a diode laser on the timing of mucosal regeneration in patients with exfoliative cheilitis. material and methods to achieve this goal, 21 patients aged 22 to 55 years who had covid-19 over the past 6 months with a diagnosis of exfoliative cheilitis k13.0 were examined. all examined patients were randomized into 2 groups: the main group consisted of 10 patients, the control group 11. all patients had

science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 11 pages: 31-35 oclc – 1121105677 publisher: oscar publishing services servi the study noted complaints of increased lip size, a burning sensation, pain when closing the lips, difficulty eating, dry mouth, and an unpleasant aesthetic appearance. the red border of the lips is brightly hyperemic with individual white-honey-colored scales, the mouth is slightly open. the clinical picture corresponded to the diagnosis of k13.0. pain intensity was assessed on a verbal scale before and 24 hours after treatment. when analyzing the dental status of patients, a high value of the simplified hygiene index ohi-s was revealed: 2.81±0.22 in the main group and 2.78±0.23 in the control groups. when assessing the factors of unsatisfactory oral hygiene from the anamnesis, it was noted that the main reasons are the impossibility and difficulty of brushing teeth due to the irritating effect of hygiene products on inflamed and eroded areas. all patients underwent traditional complex treatment, including sanitation of the mouth, administration of keratoplasty ointments, and the use of hygienic lipsticks. when various changes in the nervous system were detected, sedatives were prescribed together with a neurologist or psychotherapist. in addition, the patients of the main group received a diode laser from dr. smile (italy), wavelength 980 nm, procedure power 0.7 w, in continuous mode, in a distant technique, with a noninitiated fiber for 1 min. on a lesion area of 1 sq. cm., three times, after 2 days. research results one day after treatment, all patients in the main group noted a decrease in pain (pain intensity decreased from 5.2±0.2 before treatment to 0.18±0.12 (p<0.05)); in patients in the control group, pain intensity decreased from 5.4±0.3 to 2.9±0.16 (p>0.05). on the 3rd day after treatment, patients in the main group experienced a pronounced therapeutic effect, which was manifested in a decrease or complete disappearance of the feeling of tightness and roughness of the lips, a decrease in the intensity of inflammation, active epithelization of the mucous membrane, a decrease in pain and discomfort. on the 10th day after treatment, ohi-s in the main group was 0.61±0.22, in the control group 1.1±0.24. complete epithelization of elements in the main group was observed after 14 days, while in the control group recovery occurred on average 21 days after the start of treatment. the insignificant effect of the treatment in the control group contributed to the formation of a negative psychological attitude towards further therapy. conclusions 1. it was found that a more pronounced decrease in pain sensitivity was observed in patients of the main group, where a diode laser was included in the treatment regimen. 2. the study showed that the use of laser helped stimulate the regeneration of the mucous membrane in the lesions. the period of final epithelization of

control group 21 days. 3. the inclusion of a diode laser in the treatment regimen for patients with cheilitis is justified and can significantly increase the effectiveness of complex therapy, which is expressed in reducing pain, accelerating epithelialization, increasing the duration of remission and reducing the number of relapses. references 1. averyanov s.v. etiology of cheilitis /

abstract: the study of retinal diseases and the development of treatments for conditions such as age-related macular degeneration (amd) requires reliable and reproducible cell culture models. porcine retinal pigment epithelium (rpe) cells have been widely used due to their similarities to human rpe cells, making them an ideal model for retinal studies. however, developing a standardized and reproducible protocol for culturing these cells remains a challenge. this article presents a validated protocol for cultivating single-eye porcine rpe cell cultures, ensuring consistency and reproducibility across experiments. the protocol addresses key considerations, including tissue isolation, cell maintenance, and characterization of the cultured cells, providing a useful resource for researchers in retinal biology and ophthalmology. keywords: porcine rpe cells, retinal pigment epithelium, cell culture, phagocytosis, barrier function, immunocytochemistry, retinal research, standardized protocol, retinal diseases. introduction: retinal pigment epithelium (rpe) cells play a crucial role in the health and functionality of the retina. these cells are involved in several essential functions, such as phagocytosis of photoreceptor outer segments, secretion of growth factors, and maintaining the blood-retinal barrier. defects in rpe cell function are implicated in a variety of retinal diseases, including age-related macular degeneration (amd), diabetic retinopathy, and retinal dystrophies. porcine rpe cells have been extensively used as an in vitro model for human retinal diseases due to their anatomical and functional similarities to human rpe. the use of porcine models is advantageous because of their size and ease of handling compared to other species, such as primates. however, despite their widespread use, the lack of standardized and reproducible protocols for isolating and culturing porcine rpe cells has led to inconsistencies in experimental results. the goal of this study is to provide a validated and reproducible protocol for culturing single-eye porcine rpe cells, focusing on tissue isolation, cell culture conditions, and characterization methods. by establishing a standardized protocol, this study aims to reduce variability between experiments and enhance the reliability of porcine rpe models for retinal research. retinal diseases, particularly those affecting the retinal pigment epithelium (rpe), are a significant cause of visual impairment and blindness worldwide. the rpe is a monolayer of specialized cells located between the retina and the choroid. these cells play a crucial role in maintaining retinal homeostasis by performing essential functions, such as the phagocytosis of photoreceptor outer segments, secretion of trophic factors, absorption of light, and forming part of the blood-retinal barrier. dysfunction of the rpe is implicated in a wide range of retinal disorders, including age-related macular degeneration (amd), diabetic retinopathy, and inherited retinal diseases like retinitis pigmentosa. understanding the biology of rpe american journal of applied science and technology 2 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) cells, as well as their role in disease progression, is fundamental for developing new therapeutic strategies for retinal diseases. to study rpe cell function and the mechanisms underlying retinal diseases, researchers often use in vitro cell culture models. the development of reliable and reproducible protocols for culturing rpe cells is essential for obtaining consistent results across laboratories and ensuring the reproducibility of experiments. among various animal models, the use of porcine rpe cells is particularly valuable due to their close anatomical and functional similarity to human rpe cells. this makes porcine rpe an excellent model for studying human retinal diseases, drug testing, and understanding cellular responses to treatments, such as gene therapy and stem cell-based interventions. while the porcine model offers several advantages, the isolation and culture of porcine rpe cells have not been standardized across research laboratories. variability in culture conditions, tissue sources, and methodologies often leads to inconsistent outcomes and limits the reproducibility of experimental results. the lack of a validated, reproducible protocol for isolating and culturing porcine rpe cells further complicates the comparison of results between studies and can slow progress in retinal research. to address this gap, the current study presents a validated protocol for isolating and culturing single-eye porcine rpe cells with a focus on improving reproducibility and consistency. the protocol detailed in this article was developed to standardize several key steps, such as tissue dissection, cell isolation, and culture conditions, with an emphasis on maintaining cell viability, functionality, and differentiation. the primary objectives of this work were to: 1. establish a reproducible method for isolating rpe cells from porcine eyes. 2. validate culture conditions that allow for optimal cell proliferation and differentiation into functional rpe cells. 3. characterize the isolated cells to confirm their identity and functionality using markers and functional assays commonly associated with rpe cells. 4. provide a standardized protocol that can be readily adopted by other research groups studying rpe biology and retinal diseases. given the relevance of rpe cells in retinal diseases and the increasing need for reliable in vitro models to investigate these conditions, this study offers an essential resource for the scientific community. by ensuring consistency and reproducibility in the cultivation of porcine rpe cells, the protocol described here will facilitate more accurate and comparable results across retinal research efforts. additionally, this work may contribute to the development of new treatments for retinal diseases, such as gene therapy, stem cell-based therapies, and pharmacological interventions. in the following sections, we present the materials and methods used to isolate and culture the single-eye porcine rpe cells, followed by results that demonstrate the effectiveness of this protocol in producing functional and reproducible rpe cell cultures. methods 1. isolation of porcine retinal tissue porcine eyes were obtained from a local abattoir within two hours post-mortem. each eye was carefully dissected, and the retina was separated from the underlying choroid by gentle mechanical dissection under sterile conditions. the retinal pigment epithelium (rpe) layer was isolated from the retina using a blunt scraping technique. the isolated rpe sheet was transferred to a sterile petri dish containing rpe culture medium for further processing. 2. cell culture conditions after the rpe layer was separated, it was minced into small pieces, and the tissue was enzymatically dissociated with a 0.25% trypsin solution for 30 minutes at 37°c. the dissociation process was carefully monitored under a microscope to prevent overdigestion. following enzymatic digestion, the cell suspension was filtered through a 70 µm cell strainer to remove clumps. cells were plated in six-well culture plates at a density of 1×10^5 cells/well in a complete rpe culture medium consisting of dulbecco’s modified eagle medium (dmem), fetal bovine serum (fbs), and a mixture of antibiotics. the culture medium was changed every 2-3 days, and cells were maintained in a humidified incubator at 37°c with 5% co2. the cells were allowed to proliferate for up to 7-10 days before being used for downstream experiments. 3. characterization of cultured rpe cells to confirm the successful isolation and culture of porcine rpe cells, several characterization techniques were employed. first, the cells were assessed for the expression of rpe-specific markers, including bestrophin, pax6, and zo-1, through immunocytochemistry. additionally, the morphology of the cells was observed under phase-contrast microscopy, and confluence was monitored over the culture period. the functional integrity of the rpe cells was assessed by measuring transepithelial resistance (ter) across american journal of applied science and technology 3 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) the monolayer, which reflects the barrier function of the rpe. higher ter values indicate healthy, differentiated rpe cells with intact junctional complexes. further, phagocytosis assays were conducted to evaluate the cells' ability to ingest and process photoreceptor outer segment-like particles, a key function of rpe cells. 4. statistical analysis all experiments were conducted in triplicate, and data are presented as mean ± standard deviation. statistical significance was determined using a one-way anova, followed by tukey’s post-hoc test for multiple comparisons. p-values less than 0.05 were considered statistically significant. results the protocol successfully isolated single-eye porcine rpe cells with high yield and viability. upon plating, the rpe cells adhered to the culture surface and exhibited characteristic polygonal morphology within 24 hours. cells proliferated rapidly, forming a monolayer by day 4-5 of culture, and reached full confluence by day 7. the cells displayed typical rpe features, including pigmentation and the formation of tight junctions. immunocytochemical analysis revealed the expression of rpe-specific markers such as bestrophin and pax6, confirming the identity of the cultured cells as rpe. additionally, the cells stained positively for zo-1, indicating the formation of tight junctions, a hallmark of rpe cell differentiation. the functional assays demonstrated that the cultured rpe cells retained their ability to perform phagocytosis of photoreceptor outer segment-like particles, confirming their functional activity. transepithelial resistance (ter) measurements showed a significant increase in resistance over time, indicating that the cells were forming an intact monolayer with functional barrier properties. discussion this study presents a validated and reproducible protocol for the isolation and culture of single-eye porcine rpe cells. the approach described in this article ensures high cell yield, robust proliferation, and successful differentiation into functional rpe cells, making it an ideal model for retinal research. the results of immunocytochemistry and functional assays confirmed that the cultured rpe cells maintained key physiological characteristics, such as the expression of rpe-specific markers and the ability to perform phagocytosis. furthermore, the increase in transepithelial resistance over time suggests that the cells established a functional monolayer, which is critical for studying the blood-retinal barrier and other rpe functions. this protocol has several advantages over existing methods, including its reproducibility, simplicity, and ability to generate large numbers of cells for experimentation. by providing a reliable method for culturing porcine rpe cells, this study paves the way for future research into retinal diseases, drug screening, and regenerative therapies for retinal degenerative conditions. however, it is important to note that this protocol was performed using porcine eyes obtained from a single source. variations in tissue quality and donor age could influence the outcome of the cultures. future studies should evaluate the reproducibility of the protocol across different sources of porcine tissue and investigate potential variations in rpe cell behavior under different experimental conditions. additionally, the long-term viability and functionality of cultured rpe cells, particularly for use in transplantation or retinal regenerative applications, should be further explored. the present study highlights the development and validation of a reproducible protocol for culturing single-eye porcine retinal pigment epithelium (rpe) cells, providing a reliable model for retinal research. the successful isolation and cultivation of porcine rpe cells is an essential first step toward studying retinal diseases and testing potential therapeutic strategies. this section will discuss the key findings, potential challenges, and opportunities for future research using this protocol, including its application in drug screening, disease modeling, and regenerative therapies. 1. cell isolation and culture protocol one of the primary goals of this study was to establish a reproducible method for isolating porcine rpe cells from retinal tissue. this protocol utilizes a combination of mechanical dissection and enzymatic digestion to isolate the rpe monolayer from the underlying choroid. the tissue was carefully dissected, ensuring minimal contamination from surrounding structures, and dissociated using trypsin, which allowed for the effective separation of individual cells while maintaining high cell viability. the results showed that the protocol successfully yielded a consistent number of viable cells, with high purity and minimal contamination from other retinal cell types. this high degree of reproducibility is important for researchers aiming to obtain a reliable source of rpe cells for their experiments. additionally, the use of a standard rpe culture medium, which includes dulbecco’s modified eagle medium (dmem) american journal of applied science and technology 4 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) supplemented with fetal bovine serum (fbs) and antibiotics, ensures that the isolated cells are maintained in an environment conducive to their growth and differentiation. however, one important aspect that researchers must consider when using this protocol is the potential variability in tissue quality depending on the donor. while the tissue used in this study was sourced from a single abattoir, different sources of porcine eyes or variations in tissue age could lead to slight differences in cell yield or viability. for instance, younger animals might provide cells with better proliferative potential, while older animals may have cells that are less robust. to address this variability, future studies could explore the impact of age and source of the tissue on cell culture outcomes. 2. characterization of cultured rpe cells the success of this protocol was further demonstrated through the characterization of the cultured cells. the rpe cells maintained characteristic features, including a polygonal morphology, which is typical of rpe cells in vivo. these cells also expressed rpe-specific markers such as bestrophin, pax6, and zo-1, confirming their identity as rpe cells. bestrophin is a well-known marker of differentiated rpe cells and is involved in chloride channel regulation, whereas pax6 is a transcription factor associated with rpe development, and zo-1 is a protein involved in tight junction formation. the expression of these markers indicates that the isolated cells retained their molecular identity and were able to differentiate into functional rpe cells. this finding is significant because it confirms that the isolated porcine rpe cells could be used for downstream experiments requiring a differentiated and functional rpe model. these cells could be useful in studying disease processes such as macular degeneration, as well as for testing new drugs or interventions that aim to restore rpe function. furthermore, the phagocytosis assay demonstrated that the cultured rpe cells were capable of ingesting photoreceptor outer segment-like particles, an essential function of rpe cells in vivo. the ability to perform this key function is critical for using these cells in disease modeling, as defects in rpe phagocytosis are central to several retinal diseases, including amd. the presence of functional rpe cells in vitro provides a valuable platform for studying how rpe dysfunction contributes to retinal disease progression. the transepithelial resistance (ter) measurements indicated that the cultured rpe cells formed a monolayer with functional barrier properties. ter is commonly used as an indicator of the integrity of tight junctions between rpe cells, and the increase in ter over time suggests that the cells were establishing tight junctions and becoming increasingly differentiated. this result is particularly important when studying the blood-retinal barrier, which plays a crucial role in maintaining retinal homeostasis and preventing the entry of harmful substances into the retina. 3. challenges and limitations although this protocol was successful in producing a consistent, high-quality rpe cell culture, several challenges remain that could affect the broad adoption of this protocol. one significant challenge is the timesensitive nature of the tissue dissection. since the porcine eyes were obtained from a local abattoir, there is always a limited window of time in which the tissue must be processed to prevent degradation or loss of cell viability. the need for fresh tissue means that the protocol is best suited for use in laboratories with easy access to porcine tissue sources or for collaborative efforts with abattoirs or suppliers who can provide high-quality tissue on demand. another challenge is the variability in cell growth depending on the donor's health and age. although the cells cultured in this study showed good proliferative potential, researchers must be aware that age, tissue quality, and even differences in harvesting techniques can affect the results. developing protocols that account for such variability and improving standardization for different tissue sources could help address these issues. additionally, while this protocol was able to generate functional rpe cells for experimental purposes, longterm culture of rpe cells in vitro remains a challenge. rpe cells are known to undergo senescence after prolonged culture, and their function may deteriorate over time. future work may focus on extending the longevity of these cultures, either through genetic manipulation or by modifying the culture medium to better support long-term cell viability. moreover, the use of 3d culture models or organoids could help replicate the native architecture and function of rpe cells more closely than conventional 2d monolayers. 4. implications for future research this validated protocol opens up new avenues for retinal research, particularly in the study of retinal diseases and the development of therapies. retinal degeneration models, such as those for amd or diabetic retinopathy, could benefit from the use of porcine rpe cells, as they provide a more accurate representation of human retinal biology compared to other models, such as mouse or human cell lines. furthermore, the reproducibility of this protocol makes it an excellent platform for drug screening and gene american journal of applied science and technology 5 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) therapy studies aimed at restoring rpe function. given the role of rpe cells in retinal diseases, the ability to culture these cells in vitro allows researchers to test potential therapeutic interventions targeting rpe cells, such as gene editing or stem cell-based therapies. additionally, the use of porcine rpe cells could facilitate the development of personalized medicine for retinal diseases, as patient-specific models can be generated using induced pluripotent stem cells (ipscs) differentiated into rpe cells, providing a platform for testing drug responses or gene therapies tailored to individual patients. finally, this protocol could also serve as a foundation for studying rpe cell transplantation as a potential therapy for retinal degenerative diseases. rpe transplantation has shown promise in preclinical and clinical studies as a strategy to restore vision, and this protocol could be used to better understand the biological mechanisms underlying successful rpe transplantation and engraftment. 5. future directions looking ahead, further refinement of the protocol could focus on optimizing the culture conditions to improve the long-term viability and functional preservation of the rpe cells. developing methods to maintain the cells in a more native-like state for longer periods would be beneficial for studying chronic diseases and for long-term therapeutic interventions. additionally, exploring the use of 3d culture systems and bioreactor technologies could allow researchers to recreate the three-dimensional architecture of the retina, providing a more physiologically relevant model for studying rpe cell behavior and function in health and disease. furthermore, genetic modification techniques, such as crispr-cas9, could be applied to these cultures to study the impact of specific genes on rpe cell function and disease progression, potentially leading to new insights into the molecular mechanisms of retinal diseases. in conclusion, this study provides a robust, validated, and reproducible protocol for culturing porcine rpe cells that can be used in a wide variety of retinal research applications. by providing a standardized approach, this protocol will enhance the consistency and reproducibility of experiments across laboratories and enable new avenues of research into retinal diseases, therapeutic interventions, and regenerative medicine. conclusion in conclusion, this article provides a validated and reproducible protocol for culturing single-eye porcine rpe cells, which can serve as a valuable resource for researchers investigating retinal diseases and therapies. the protocol

industrial waters. production of these used adsorbents based on local raw materials is one of the urgent problems of today. activated carbon is a carbonaceous material processed by special methods, during which organic raw materials are thermally and chemically activated. in an airless environment, it is heated to reduce the noncarbon components (a process called carbonization) and then reacts with the gas, corroding the surface to form a microporous structure (a process called activation) [1]. wastewater treatment using the adsorption method is recognized as the most effective method, due to the large number of its sources, variety of types, low cost from the economic point of view, regeneration properties, high efficiency in cleaning and ease of use, etc. at present, methods such as adsorption, chemical treatment, ion exchange, and coagulation are widely used for the purpose of wastewater treatment [2]. wastewater treatment using the adsorption method is recognized as the most effective method, due to which it has a number of advantages, such as the large number of sources, variety of types, low cost from the economic side, regeneration properties, high efficiency in cleaning, and ease of use. . it has been proven that the efficiency of the adsorption process can be reached up to 99.9% [3]. at the same time, this method is a simple and economical method compared to other methods, and it has the characteristics of good purification of wastewater from many types of pollutants, including dyes. cotton stalks are a global agricultural residue with limited economic importance, with annual production of approximately 50 million tons. the fruit (cotton fiber), stem, pod and leaf of goza plant are distinguished by the storage of different amounts of cellulose, and this is shown as a promising and ecologically stable raw material for obtaining cellulose [4]. as a result of studies from the literature, the composition of various components of the cotton stem was studied. according to their results, the content of α-cellulose in cotton stalk was 42.25%, which is higher than other lignocellulosic resources, and the contents of lignin and ash were 20.62% and 2.71%, respectively. is [5]. in the climatic conditions of uzbekistan, cotton is one of the most cultivated types of plants. more than 60% of the agricultural areas of our republic are specialized in cotton cultivation, especially for the cotton crop of 2024, fertile cotton varieties obtained by various genetic methods were planted on nearly 1 million hectares. after the cotton crop is harvested, some of the cotton stalks, which are abundant in the fields, are harvested as fuel, and the rest is left in the fields, which becomes a problem for replanting. methods in the production of activated carbon, the starting material is first heat-treated in an airless environment, https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

picture: 3 ir spectra of adsorbents obtained by thermal treatment of cotton stalk and cotton shell ir spectroscopy of thermally activated adsorbents based on cotton stalks and cotton bolls was studied. since the structure of the raw materials is close to each other, the results of ir spectra are also similar to each other. according to the ir spectra, valence vibrations specific to the oh group were detected in the 3335 cm-1 region, and these valence vibrations indicate the presence of partial water molecules between the coal pores. valence vibrations characteristic of c-h bonds of saturated and unsaturated hydrocarbons were observed in the peaks of the 2884 cm-1 spectrum. valence vibrations characteristic of unconfigured c=o group in lignin and hemicellulose were observed in 1673cm-1 and 1653 cm-1 areas, respectively. the formation of aromatic compounds such as aldehydes, ketones, aromatic hydrocarbons here occurs as a result of the thermal decomposition of lignin and hemicellulose, which are the main components of raw materials. in the 1394 cm-1 area, deformational vibrations characteristic of the c-h bond of saturated hydrocarbons were observed. the deformation vibrations observed in the 1219cm-1, 1189cm-1, 1137cm-1 areas represent the c-c bonds in the structure of cellulose, hemicellulose and lignin, which are the main components of raw materials. we have

tashkent medical academy, urgench, uzbekistan received: 23 december 2024; accepted: 25 january 2025; published: 27 february 2025 abstract: this work presents the results of the potentiometric determination of aqueous, non-aqueous and mixed solvents of copper (ii), zinc (ii) and chromium (iii) cations: (propanol-2, acetone, methyl ethyl ketone, toluene, carbon tetrachloride, dimethylformamide) and their mixtures with water in a ratio of 1:1 and 1:19 by volume, the ratios of acid-base titrations are given. the quantitative results of the titration on a per kilote basis for the indicated cations cu2+, zn2+ and cr3+ are based on the acidity constants of these cations assessed in the solvent environment specified above. the influence of the physical and chemical properties of solvents on acid-base titrations was studied. due to the increase in the proportion of non-aqueous solvent in the solution, the dielectric constant of the solution decreases, and this leads to an increase in the ability to quantify acid-base titrations. keywords: potentiometry, metal cations, copper, zinc, chromium, dielectric constant, acidity constant. introduction: it is known that heavy metal cations in solutions have their own acidic properties. therefore, they are also called aprotic acids or lewis acids. the acidic properties of metal ions depend on their position in the periodic table, on the ionic charge and on the number of anions associated with the cation. the cations cu2+, zn2+ and cr3+ are aprotic acids, which do not retain protons, and have wetting acidic properties of varying strength in solutions depending on their ionic charge. according to the literature, there are few works on their titrimetric acid-base determination. given their acidic properties, ions can be titrated as acids in a mixed aqueous-non-aqueous solution. because of this, we carried out their titrimetric analysis in non-aqueous solvents mixed with water. it was of interest to determine the content of aprotic acids, which play an important role in the life of living organisms. to develop methods for the analysis of these aprotic acids, model solutions of the substances under study were taken and titrated based on acid-base reactions. as shown above, aprotic acids exhibit acidic properties of varying strength. of the above aprotic acids, copper and zinc are dibasic acids, and chromium is a tribasic acid. taking into account the acidity of various solutions of aprotic acids, methods of their acid-base potentiometric titration can be recommended. in aqueous solution they are mainly titrated according to the second acidity constant. the addition of nonaqueous water-miscible solvents to water improves the conditions for titration of aprotic acids. in this case, it can be ensured that they can be titrated against all acidity constants. methods the chosen objects were chlorides and sulfates of aprotic acids of copper (ii), zinc (ii) and chromium (iii). thus, ethanol, 2-propanol, acetone, methyl ethyl ketone, toluene, carbon tetrachloride, dimethylformamide and their mixtures with water were used as solvents. https://doi.org/10.37547/ajbspi/volume05issue02-08

in ethanol and 1-propanol, as well as solutions of potassium acetate in suitable solvent media, were used as titrants. as a research method, we used potentiometric titration from electrochemical analysis methods. to estimate pka values, the henderson method was used, based on potentiometric titration with glass hydrogen-selective and silver-silver chloride electrodes. the essence of the method is that, under the same conditions, two acids are titrated with a strong alkali solution: one of them serves as a standard, and the second as the acid being studied. for a standard acid, the acidity constant in a given solvent must be known. based on the results of potentiometric titration, titration curves are constructed and from these curves the values of half-titration potentials are determined and the values of acidity constants are calculated using the formula: 1/2 1/2 x o x o e e pk pk  − =  (1) which is: xpk – indicator of the acidity constant of the acid under study; opk – indicator of the acidity constant of the acid standard; x 2/1e – half-titration potential of the acid under study, мв; o 2/1e – halftitration potential of acid standard, мв; 𝜃=58 (above 200с) мв or 𝜃=59 (above 250с) мв. benzoic acid was used as the standard acid. a hydrogen-selective electrode was used as an indicator electrode, which was adjusted according to the method attached to the ph meter using two buffer solutions (in an aqueous solution). the reference electrode was a silver chloride electrode filled with a saturated aqueous solution of doubly recrystallized potassium chloride. results table 1 shows the results of the determination of chromium (iii) 3crcl in the form and 342 )so(cr not only in alcohols, but also in ketones, dmp, toluene and carbon tetrachloride. as can be seen from the data in table 1, by decreasing the amount of acids in the test solution, the relative standard deviation increases slightly. for chromium (iii), the relative standard deviation of the determination also depends on both the amount of the substance and the composition of the solvent and the dielectric constant of the medium. thus, when titrating small amounts of chromium (iii), it is higher. table 1. results of potentiometric determination of chromium (iii) in solvents with different dielectric constants (n=5, xx  , p=0,95) aprotic acid solute  introduced, mg found, mg s rs

non-aqueous solvent and a decrease in the dielectric constant of the medium. the exception is mixtures of acetone with toluene and carbon tetrachloride. in these solvents, although the dielectric constant is lower, the relative standard deviation is higher. it follows that the accuracy of the determination is influenced not only by the nature of the conjugate base (anion) of the acid being determined and the physical properties of the solvent, but also by its chemical nature. the accuracy of the determination of chromium (iii) ions also depends on the conjugate base. since chloride ions are a weaker base than sulfates, the accuracy of the determination of chromium chlorides is higher than the accuracy of the determination of sulfates. the same pattern persists when titrating zinc

results of titration of chlorides, sulfates and acetates of copper (ii) in various solvents are given in table 3. both anhydrous chlorides and acetate crystal hydrates were taken for analysis. as can be seen from the data in table. 3, the accuracy of the determination of copper aprotic acids depends on the strength of the conjugate base. at similar amounts of chlorides, sulfates, and acetates, the relative standard deviation increases with increasing basicity of the anion. the exception is mixtures of acetone with toluene and carbon tetrachloride. in these solvents, although the dielectric constant is lower, the relative standard deviation is higher. it follows that the accuracy of the determination is influenced not only by the nature of the conjugate base (anion) of the acid being determined and the physical properties of the solvent, but also by its chemical nature. based on the developed analysis methods, the content of harmful heavy metal ions in various food products (meat, liver, spleen, milk, feta cheese, etc.) and other environmental objects was determined. conclusions 1. the possibility of potentiometric acid-base determination of the above metals in water, aqueousnon-aqueous and mixed solutions was studied. 2. the data obtained from potentiometric acid-base titration of aqueous aqueous-non-aqueous and mixed solutions of aprotic acids can be concluded that the studied acids are well titrated with solutions of hydroxide, ethylate, propylate, isopropylate and potassium acetate with a properly selected solvent. a decrease in the dielectric constant and autoprotolysis constant of the solvent improves the conditions for potentiometric titration, which is expressed in an increase in the potential jump on the titration curves. 3. it has been established that the conditions for acidbase potentiometric titration improve with an increase in the proportion of non-aqueous solvent, when the dielectric constant of the medium decreases. 4. the developed methods of acid-base titrimetric analysis have been applied to the analysis of metal cations in various natural objects, such as meat, dairy products, water, soil and plants. references

introduction to pollution and its impact on ecosystems pollution is a ubiquitous environmental problem that interferes with the balance of nature in multiple ways. the introduction of contaminants has diverse effects, such as changes in habitat and decreased biological productivity, leading to human health hazards. the problems caused by pollution are potentially global, as air and water move across the continents. an enormous array of contaminants is released into the environment, making it difficult to deal with because sources are varied, constituents are numerous, and impacts are widespread. pollution can be abated through wide-scale implementation of awareness to reduce the personal contribution of pollutants to the environment. the purpose of this report is not to suggest methods for controlling pollution but to discuss ecological changes following pollution and look for ways to manage pollution. one objective of ecosystem management is to restore the balance; this is likely to include a wide range of more or less ad hoc actions. if there were a law regarding the effects of pollution on our ecosystem, it would be that 'every action has an equal and opposite reaction.' to be more specific, each decision made regarding the emission of pollutants would subsequently produce an environmental impact of the same breed but of proportionate effect. in fact, this behavior is not so easily defined. the relationship between environmental constituents, on both an additive scale and a multiplicative scale, always leads to the same bottom line: increasing pollution levels can only have negative effects on ecosystem health. ecosystem health is managed by increasing awareness and https://doi.org/10.37547/ajbspi/volume03issue03-01

pollution pollution, unattended, invites ecological disasters like climate change, increased intensity of natural calamities, glacial flooding, and new diseases. simply defined, pollution is the introduction of contaminants into the natural environment that cause adverse change. it can be classified on the basis of material and the area in which it is spread. here i adopt the latter system and recognize four types of pollution: air pollution, water pollution, soil pollution, and noise pollution. air pollution is mainly due to the excessive emission of greenhouse gases and organic gases, mainly as a result of gasoline combustion in cars, diesel motors, planes, industrial plants, and chemical factories. water pollution is of far-reaching dimensions and consequently draws into its fold several lifethreatening diseases. some of the major water pollutants include industrial wastewater from tanneries, paper, textiles, cement, steel, sugar, petrochemicals, and agricultural wastewater from numerous sources. soil pollution poses a more serious threat to agriculture than the other forms because, ultimately, land is the place where all toxic wastes are finally deposited. major categories of soil pollutants are heavy metals, high salt in the soil, radioactive substances, coal tar, and dioxins. as far as noise pollution is concerned, we are all suffering from it under our flight paths or on the busy roads of big cities and towns. it also has its impact on wildlife. a more detailed explanation of these pollution types is given in the following sections. each of these subsections will provide the general nature of the pollution type, major sources or causes of the pollution, and the common effects it can have. as pollution is of major concern, one can note the extensive and specialized strategies adopted for their control and management. the ecological consequences of pollution pollution has a great many ecological consequences. through bioaccumulation and biomagnification, pollutants can disrupt food webs. this hurts not only predators and herbivores higher up on the food chain, but also the concentration of primary producers, such as phytoplankton and algae on which all life in the ocean depends. bioaccumulation, in particular, often harms the target pests and pathogens. a variety of pollutants harm biodiversity by harming some species directly or often by harming an essential mutualist or competitor whose abundance and thus whose impacts are regulated by the essential species. in many cases, pollutants or simply high levels of naturally occurring compounds can kill or injure many plants or other primary producers, resulting in less carbon storage and degraded habitats, which may ultimately contribute to the loss of species that utilize these source habitats and suboptimal conditions for sexual maturity and https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 20 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 10 pages: 17-35 oclc – 1121105677 publisher: oscar publishing services servi mating. species may face extinction from habitat loss or other forms of pollution, such as disruption or loss of essential mutualists or antagonists. because ecological communities are typically linked by interactions such as pollination, herbivory, competition, and predation, detrimental impacts of pollution may cascade throughout entire ecosystems, which may then ultimately destabilize ecosystems. ecosystem services, such as clean air and water and buffering against floods, have become increasingly degraded by a traditional focus on production without concomitant strategies for pollution control. total abatement costs of these ten compounds are surprisingly cheap: only a small percentage of federal spending on environmental protection. the relative paucity of information on these chemicals, coupled with the difficulty of utilizing traditional cancer bioassay data, suggests the use of the precautionary principle in risk assessment to keep the possibility of ecological catastrophe minimal and to work off of very conservative data. case studies: environmental damage from pollution events case studies have been included to illustrate the kinds of damage that can be caused by pollution incidents that have occurred. in australia, pollution incidents tend to involve industrial spills into waterways or poor management of waste. this is an area where the understanding of the effects on the environment is well developed. the aims and work of a clean-up response tend to occur immediately after the event. there is more likely to be a focus on the economic aspects of the incident, including short-term clean-up operations and the protection of assets. the analysis has found that in practice clean-ups tend to be less successful than the proponents claim but are also less likely to be a disaster than the critics' pessimistic stance. a detailed case study is included in this group in order to help in understanding the choices made and consequences suffered by citizens in the hope that we can use it to limit the magnitude of further events. the case studies are presented in this way in order to avoid the appearance of a prediction of future scenarios. three separate incidents, which have all had kooris as actively affected citizens, are presented. the analysis of each of the three case studies is intended to show the range of choices of action made and the range of consequences suffered by populations. it is intended to suggest some of the simplifications that are embedded in the assumptions informing the choices made. further, because pollution tends to be a legacy issue in that the effects may show up in years, as well as in the very short term, the case studies attempt to show what the impacts on those affected can be in the long and medium term. although it is a difficult and complex game of 'false reasoning', it is impossible to stop enough pollution incidents of this magnitude actually occurring to judge validity. the case studies presented are based on relatively rare examples of corporate incidents. the more common https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 21 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 10 pages: 17-35 oclc – 1121105677 publisher: oscar publishing services servi municipal incidents were typical of those discussed but more difficult to access. the choice of state for the case studies was not based on any assumption about the political propensities of queensland or victoria. the decisions of these governments and their instrumentalities to commit these acts were perforce arbitrary. they could, given the pro-market propensities of both labor and the coalition governments that have governed these states, have occurred under either government. the analyses reveal that the values of the costs of environmental damage to an economy factored into the assessments are based on the short-term costs of mitigating damage and risk of pollution disasters as an externality to the polluting company. there is no exploration of the ways this may or may not actually be the case. this is very familiar territory in environmental pollution impact and risk assessments. global initiatives and policies for pollution control also express concern with the rate of implementation of planned responses, positing that profound transformation is necessary for reaching global environmental objectives. this form of international collaboration is essential for addressing pollution on a global scale as many pollutants are not confined by national borders. policymakers restate their aim to "strengthen the global response to the threat of climate change, including... the impact of responses to changes in the way of working required to mitigate and adapt to climate change". the inconsistency between these words and results is well recognized in the international environmental law literature. primary objectives of the convention on biological diversity, the most comprehensive international environmental treaty, are to give effect to the development, conservation, and sustainable use of biodiversity, and encourage international cooperation. the facts available would, therefore, suggest a likelihood that the development and addition of planned registered methods and standards, for purposes of addressing global challenges, may have a possibly greater anticipated rate of implementation. each of the five types of methods could be used on their own but are most powerful when used in combination; investors could receive finance from the international environmental agreements that direct finance to their chosen mitigation methods. technological innovations for pollution monitoring and control technology plays a critical role in monitoring and controlling pollution at different levels. advanced technologies, such as remote sensing, artificial intelligence, iot systems, and data analytics, have made it easier for scientists, users, and other stakeholders to monitor various types of pollution. remote sensing technologies have advanced significantly and are designed to monitor a wide range of pollutants at various resolutions, from large-scale monitoring where national and international authorities are involved to high resolutions where https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 22 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 10 pages: 17-35 oclc – 1121105677 publisher: oscar publishing services servi regional monitoring of chronic pollution is conducted. real-time monitoring systems, combined with smart analytical tools like ai and data analysis, help evaluate environmental health status by identifying sources of pollution, forecasting, providing early warnings of pollution disasters, assessing pollution levels and sources, and managing and controlling pollution in the environment. these monitoring and evaluation data are very useful for identifying problems, discovering reasons and causes that harm the environment and people, and providing necessary information for policymaking to minimize the harmful effects of pollution on the community. there are successful stories and case studies for controlling pollution through technological interventions. the deployment of air and water monitoring technologies has seen improvements in pollution data reporting and control. however, such technologies are implemented with limited access in rural areas, low-income countries, and low-income communities in high-income countries. advanced technologies present tremendous opportunities for improving human-environment interactions in urban areas and addressing pollution problems. to be most effective, these technologies must be coupled not only with policy initiatives but also with community activism and legal intervention that allow oversight to be integrated into community control. in addition, data privacy remains a pressing concern because modern pollution models rely on large, dynamic databases that continuously update. several well-known concerns about data privacy indicate that a technological solution alone is insufficient for mitigating pollution through improved sanitation. in summary, this perspective proposes a "technological trap" where technology created for monitoring ends up becoming a new tool for polluting. there are, however, substantial opportunities for technology to be part of the solutions for sustainable and satisfactory human exposure to urbanization and industrialization. the application of modern technology to predict the fate of pollution in the environment will help control pollution and minimize its impact on human health through the harmonization of environmental quality and the natural role in society. providing a sustainable environment for urban development and industrial output can be achieved by applying the above approach in society, whether in developed or developing countries. however, it is necessary to focus on the community's role in the strategic vision in order to take action towards social justice and public health, and to promote policies for improving the environment. technology should be seen as a means for progress to help reduce and avoid pollution. people and communities must be empowered to control their environment to become more engaged for a healthier environment and planet. bioremediation: nature-based solutions for pollution cleanup bioremediation: nature-based solutions https://doi.org/10.37547/ajbspi/volume03issue03-01

volume 04 issue 10 pages: 17-35 oclc – 1121105677 publisher: oscar publishing services servi using the capacity of ecosystems to deal with waste, including pollution, is the subject of bioremediation. bioremediation means using living organisms, mostly microorganisms, plants, and their enzymes, to remove pollutants from an environment. it is a more general term that encompasses phytoremediation but also includes other aerobic and anaerobic processes carried out by microorganisms in water, soil, and sediments to remove organic and inorganic pollutants. depending on the system being treated, gases, temperature, ph, and other environmental parameters may be adjusted to ensure optimum speed and efficiency. bioremediation is an attractive option because of its flexibility, minimal risks to humans and the environment, and generally lower costs relative to traditional technologies. despite some disadvantages and limitations, several well-documented case studies support the effectiveness of bioremediation in the cleanup of soil, water, and air polluted with various compounds. experience to date has revealed the importance of carrying out a preliminary site visit and an inventory of the land's ecological characteristics to choose or tailor a bioremediation strategy for optimum results. by understanding the local flora, fauna, hydrology, microbiology, and biogeochemistry, we can ensure that site-specific advantages can be linked and possible adverse impacts can be eliminated or minimized. bioremediation is not a universal solution; however, several challenges, limitations, inconveniences, and business culture constraints have been reported. these include substantial start-up periods for microbiological treatments, management and regulatory challenges, and limited field applicability. finally, we advocate that the optimal approach for the future is to pursue a combination of ecological knowledge, technological research, and sustainable environmental management. in this context, bioremediation offers essential mechanisms and applications for a sustainable future. sustainable practices and green technologies to combat pollution achieving sustainability in industrial and personal living would lead to the reduction of pollution and its detrimental effects. the key to achieving this goal is the adoption of technology and practices developed according to the principles of green chemistry and engineering to reduce the ecological consequences of an anthropocentric industrial world. to reduce the outflow of pollutants from urban centers into the neighboring rivers or coastal seas, it is important to address the daily lifestyle performed in these areas. this topic illustrates a variety of appropriate strategies and alternative technologies available for sustainable living. average people and communities support many practices aimed at avoiding environmental pollutants in their lifeways, such as waste reduction, material recovery for recycling and reuse, extensive energy efficiency, energy saving, cleaner energy options, development of urban farming and gardening, and https://doi.org/10.37547/ajbspi/volume03issue03-01

practices produces appreciably less waste, recovers significant portions of material before undergoing further processing, or consumes less starting raw material, which then reduces waste generation. the application of green technologies makes it possible to lessen emissions continuously and in considerable amounts. the strategy provides clear guidance on what we will have to achieve to live sustainably on earth as part of the natural world. the objective from this perspective is to provide evidence-based reasons for why we need to change the way we currently do things. though manageable technology exists, difficulties at the social level focus on its acceptance by individuals or society, and can be listed with four main aspects: uneconomical, limited technical skills, resistance to lifestyle changes, and general disinterest in sustainability. since industry is responsible for much of the pollution, there have been many voluntary efforts by companies to lessen their negative impact on the environment by integrating sustainable practices into their corporate strategies. to promote pollution prevention as the basic strategy of decreasing pollutant output by using a life cycle viewpoint, some practical methods must be implemented. integrating pollution prevention into some company sectors that work at the local level can increase the adoption of sustainable practices with a visible and measurable output. analysis of pollution reduction has also resulted in identifying pollution management technology that is profitable and advantageous in corporate contexts. promoting the advantages and results of their applications in a variety of industries and places to contribute to the enhancement of sustainability for society is our real intention. role of education and awareness in environmental protection the general understanding among all the text presented is that education and awareness are essential to environmental protection. first and most importantly, education can inform people about the effects of pollution on the environment and various mitigation strategies, from smaller-scale, less expensive actions to larger-scale, more expensive ones. people who are informed and educated about these issues can also take actions in their daily lives to protect the environment from pollution. governments can encourage these actions through incentives and policies, as well as by taking actions themselves. second, once people are educated about environmental issues and are aware of various strategies to mitigate pollution, they are more likely to take these issues into account when forming opinions about policy. if voters are concerned about environmental issues such as pollution and are educated about strategies that could be effective at mitigating these problems, then they may be more likely to advocate for and vote for environmental https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

1121105677 publisher: oscar publishing services servi protection policies. for these reasons, education may be a good investment that protects the environment long into the future. policymakers around the world have called for increased investments in environmental education and awareness campaigns as a proactive strategy for protecting the environment. educating people about environmental issues and inspiring them to take action are key solutions to address pollution and other environmental challenges. from a young age, school curricula and community programs can foster a culture of environmental responsibility to help prevent pollution in the first place. education about and awareness of pollution’s impacts have helped drive policy changes in many countries—that is grassroots democracy in action. educators should collaborate with policymakers and other organizations to develop effective environmental awareness campaigns as a fundamental component of any environmental protection strategy. print, broadcast, and online media can be effective platforms for environmental education since they can reach a relatively large audience. while further research is needed to quantify the impacts of these campaigns, educators can engage more broadly in social media and other digital platforms to promote environmental literacy and inspire action. in conclusion, investing in pollution education efforts can help reduce environmental impacts for future generations. community engagement and grassroots efforts in pollution mitigation community engagement and grassroots efforts are important parts of any pollution mitigation strategy. the consequences of community action can extend far beyond the individuals involved in the effort. in an environmental landscape dominated by daily localized ecological catastrophe, we need motivated and driven community leaders who value their local community and are invested in enacting tangible change. indeed, the inability to engage with local customs and bring about a direct on-the-ground difference can kill a project dead in the water. the franchises are founded on the idea that community values and embedded ethos can be powerful motivators for individuals engaging in collective movements. in a world where humanity is in the odd position of being a participant, co-producer, and innocent victim in numerous latent crises, such effects cannot be underestimated. there are various forms that such projects and activities might take, fitting broadly into three unique brackets: clean-up and waste collection, educational programs and training, and advocacy and policy development. the past few years have seen a corresponding surge in the use of social media and the development of digital communities of supporters. these grassroots, researcher-led community endeavors have great outreach interest and potential, suggesting a philosophy to integrate the roles of these multidisciplinary groups and act as cohesive agents for change-makers. successful case studies also report cleaning up and reducing pollution and watering https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 26 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 10 pages: 17-35 oclc – 1121105677 publisher: oscar publishing services servi points, and people feeling more engaged and involved in the natural environment, with positive knock-on physical and mental health benefits. what is important is that these achievements have increased the extent of the local clean-ups that help in the removal of large items of debris, while the long-term day-to-day cleanliness of waterways is an important task that ultimately needs to be taken over and sustained by the local community's partnership and sustainable wildlife management. corporate responsibility and sustainable business practices the deterioration of environmental quality and the rise in different types of pollution have grave global ecological consequences. in accordance with the breadth of environmental problems and the range of human behavior that impacts nature, the strategies for solving these problems are based on international agreements between states, global unions, compensation mechanisms, and corporate responsibility. corporate contribution towards improving water, air, and soil quality is usually realized through a company’s choice of whether or not to adopt sustainable business practices and what type of strategy it should apply. the existing literature explores corporate profitability, the consequences of adopting sustainable practices, stakeholder theory, corporate voluntary disclosure, or corporate social responsibility activities. the efficient management of natural resources and the reduction of damage caused by pollution depend on companies, which have the potential to decrease their dependency on natural resources and to slow and reverse environmental degradation. for this reason, businesses are being encouraged to diminish their ecological footprint. cost reduction, discharge taxes, governmental awards, and sustainability reporting are all factors that can lead the company to a sustainable turning point. conversely, prohibitive costs, technical barriers, and the lack of public enforcement are some of the major present-day barriers to limiting the ecological damage induced in the corporate area. although not easy, the task is achievable. the popularity of ethical consumerism, the increase in the number of people making ethical investments in specific projects, and the wave of decisions taken by multinationals and large conglomerates are all indicative of these statements. accordingly, the following paragraphs aim to describe the role that corporations play in mitigating pollution by assuming corporate sustainability. the main part of the current paper describes the main strategies for mitigating environmental issues assumed by relevant corporations as they adapt to pollution challenges. in addition, the obstacles that await an environmentally friendly company in the modern world are also described. finally, the final part is reserved for the outcomes of some sustainable companies. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 27 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 10 pages: 17-35 oclc – 1121105677 publisher: oscar publishing services servi the economics of pollution: cost-benefit analysis and externalities to an economist, pollution imposes costs, the most obvious and pressing of which are human health impacts, typically shortening or impairing the lives of those who suffer disease because of environmental contamination. one might also feel a sense of ethical and aesthetic loss at seeing an ecosystem thus degraded. consequently, evaluating strategies to reduce these detrimental impacts on the environment carries weight on its own. many communities, particularly those surrounded by the scars of industrial plundering, are eager to reclaim their environment for its own sake. the main concern of this chapter, though, is the economics of pollution or environmental degradation. while the environmental externalities addressed in this chapter are expressed as health effects and ecosystem impacts, it is important to recognize the broader definition of adverse environmental and human health consequences possible from unregulated pollution. the importance of evaluating these environmental costs lies in the benefits of reducing them. all pollution abatement policies should be evaluated with respect to the decline in health and ecosystem impacts associated with a given strategy, relative to other strategies. there exists a wealth of literature suggesting economic methods for quantifying and valuing the effects of pollution on human health and ecosystems. on a broader developmental scale, making the costs of environmental deterioration apparent is important for setting a sustainability agenda, which aims at environmental conservation for the sake of future benefits worth weighing against current economic gains. reflecting genuine physical and ecological costs of pollution is a crucial starting point in defining sustainable cost-benefit results. we discuss some key issues on this combination of development and environment in a more exploratory way. right now, we will expound on some ideas to bridge the gap between economic development and environmental conservation. legal frameworks and regulations for pollution control the vast amount of pollution occurring in nearly every part of the world calls for efficient control measures. consequently, several national and international laws have been put in place in an attempt to prevent pollution and protect human health, as well as the environment. this section presents an overview of critical components in this area. a good regulatory framework is a necessary condition to protect living and nonliving nature and to decrease pollution. strengthening of special national laws had a positive impact on the reduction of the amount of pollutants released into the atmosphere. it also stimulated the development of new technology that could be used to produce goods while emitting reduced amounts of pollutants. national laws or regulations have been introduced to regulate the way https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 28 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 10 pages: 17-35 oclc – 1121105677 publisher: oscar publishing services servi industries produce goods and services. even with relatively strict laws providing protection for the environment, we can see that not all facilities comply with these laws. however, not all environmental acts are as strict: in developing countries, less strict environmental policies can be observed that support faster economic growth. one of the case studies shows that, when trying to prohibit certain activities, it is best to be as specific as possible while threats to health and the environment should be reported in a balanced way to prevent nagging from the companies. if economic growth is to be achieved, clear incentives and policies to push companies into compliance should be established. it is very clear how the regulatory regime from the 1990s has resulted in the rapid abatement of air pollution. although some companies in certain countries have still not achieved full compliance, there is evidence of serious movement toward this ideal to the advantage of public health. international collaboration in addressing transboundary pollution most of the damage inflicted on the environment transcends national boundaries. air and water pollution do not respect frontiers. pollution knows no borders. that is why it is so important to facilitate international cooperation to address the common environmental problems that neighboring countries encounter. indeed, bilateral relations could create additional opportunities for sharing information, site visits, alert systems, and other informal mechanisms that could foster future regional agreements. while the countries of eastern and western europe are at the forefront when it comes to looking at international cooperation on environmental issues, in other regions of the world, a number of agreements have been put in place to address specific transboundary environmental and natural resources management issues. there are many agreements, but the actual implementation of collaborative programs addressing pollution across borders is usually slow and subject to many issues of scale and entire national management and policy framework constraints. moreover, differences in the regulations adopted, enforcement capacity among the countries, technical and financial resources, and climate and pollution characteristics within and between participating countries, as well as the needs and aspirations of the populations in the joint pollution problem areas, are among the factors that can have an impact on the successful implementation of bilateral and regional agreements. the issue of shared river basin management is a policy priority for many developed countries. bilateral projects, by offering the prospect of coordinated and often joint funding support, are likely to have a greater effect and be very valuable in addressing international water management and policy objectives. many projects have been implemented to provide the basic knowledge for developing and implementing https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 29 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 10 pages: 17-35 oclc – 1121105677 publisher: oscar publishing services servi transboundary agencies and agreements. intergovernmental organizations have supported some of these activities. some integrated projects have shown that it is possible to manage such developments effectively. however, due to financial and technical problems, few have developed the capacity to implement and maintain them fully and sustainably. the international implementation of the european water framework directive will strengthen existing cooperation within western europe but will also create the major challenge of cooperation between western and eastern european countries and in associating countries where there is less expertise, funds, and capacity to implement them. it is not enough simply to have an internationally acceptable set of water bodies requiring a consensus. both the surface and ground waters have to be managed sustainably at the international scale, and support from appropriate scientific and monitoring capacity will be facilitated and advanced by a series of initiatives that develop at a local, national, and regional level in terms of developing policy, improving monitoring capacity, facilitating dialogues, and building partnerships. climate change and pollution interactions interactions between climate change and pollution are ubiquitous. in some instances, pollution contributes to higher rates of global warming and climate change with increases in greenhouse gases and particulates that increase the percent of sunlight reaching the ground and also absorb atmospheric co2. on the other hand, climate change may lead to more pollution, as with increasing wildfires and flooding leading to more particulate matter being released. future research should advance our understanding of the ecological and public health implications of the interactions between climate change and pollution. the implementation of integrated policy strategies is increasingly being advocated to simultaneously address the driving forces of climate change and pollution. some examples of existing integrated policy strategies to mitigate and reduce waste and resultant pollution while moderating climate change include cap and trade programs, incentives for steel and cement plants to shut down soon, and carbon taxes that target high emissions. several case studies reviewed highlight a range of existing policy efforts and incentives that aim to reduce pollution while mitigating climate change or increasing carbon sequestration or consumption of pollutants into less toxic forms. policy responses to mitigate pollution are generally founded on environmental protection laws, for which several international agreements have been reached. urbanization and industrialization: balancing development and environmental protection urbanization is occurring at an unprecedented rate, and by the end of the 21st century, more than 85% of the human population is projected to live in cities. rapid urban growth without accompanying infrastructure investment has resulted in overburdened services, overcrowding, a build-up of https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 30 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 10 pages: 17-35 oclc – 1121105677 publisher: oscar publishing services servi slums, increased pollution, traffic congestion, and depletion of resources. cities burn disproportionate levels of resources, such as fossil fuels and minerals, and exacerbate the degradation of non-renewable resources. they also produce waste and pollution, resulting in immediate and long-term ecological impacts. to build a more sustainable city for the future, the global community should concentrate on balancing development with environmental preservation by considering geographical factors, increasing green spaces, and fostering sustainable lifestyle policies as part of urban planning. some cities in the industrial world are already emphasizing knowledge industries that provide jobs, clean high technologies, and goods and services that center on sustainable lifestyles. some european cities are good examples of cities where green parties and conservationists have worked to curb sprawl and include cheap and efficient public transportation and green areas. many northeastern cities in the u.s. and in europe are brownfield sites that might cause respiratory illness, cancer, and other diseases because the soil and groundwater are contaminated. yet, behind all these initiatives and good works, real progress is hard to come by. this is because economic growth and the development of a sustainable city can conflict. economic growth is based on the exploitation of resources and ecology, whereas sustainability is based on no or minimal resource use. economists rarely understand this consumptive conflict and thus promote economic growth without consideration of the demands it places on ecosystems. community and public participation in city planning, conservation, technology selection, and the political process is critical if a change in the city's direction is going to be achieved. industrialization is a planned, long-term, and participatory process where the periphery of the city adjusts slowly and in a sustainable manner. the role of indigenous knowledge in pollution management the current strategy of promoting the use of international scientific knowledge by policymakers and including it in educational curricula and research activities at universities is ineffective in preventing pollution and protecting the environment in general. the main reason for this is that in terms of pollution generation, neither scientific knowledge nor public policies are ‘sufficiently effective’. there is an urgent need for new strategies to prevent pollution. some theoretical and empirical approaches indicate that these strategies should be built on the identification, analysis, and use of indigenous knowledge (ik). for centuries, indigenous peoples have developed sound ecological procedures in managing their rich resource environment. they draw upon a deep environmental sensitivity and ecological understanding. these people have developed systems of values and rules designed to facilitate the sustainability of the entire biological matrix that supports them, and they have come to understand https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 31 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 10 pages: 17-35 oclc – 1121105677 publisher: oscar publishing services servi quite well the ecological costs of bypassing these rules. indigenous ecological knowledge and systems of resource management are based on the recovered principles of ecological equilibrium. although anthropogenic impacts on ecosystems were statistically as serious as they are now, ecosystems somehow were able to recuperate in the past. thus, such evidence always throws important light on how the environmental resilience of land can be restored, and it would appear to be an essential part of the restoration of the sick landscape. clearly, the dire state of the world’s ecosystems, and the ever-pressing need to find strategies for restoring them, gives additional urgency to this research. research has shown that combining indigenous knowledge with scientific knowledge can lead to effective management. common causes of environmental degradation include deforestation, soil erosion, and pollution. in view of that, techniques for analyzing the iroc would need to be developed to suit different pollution problems. other approaches, case studies, and the implementation of the iroc where indigenous knowledge is part of the solution include research projects on the relationships between biodiversity and beach use, selected examples of appropriate technologies in coastal systems, public participation in coastal planning, ecosystem structure and function in wetlands, and live kelp-harvesting systems. regular evaluation and publication of case studies continually set additional paradigms for research excellence. a review of the successes of such studies gives those undertaking the review a different viewpoint on their own approaches and encourages never-before-tried methods to discover and be developed. an annual publication that reflects a strong interdisciplinary approach provides a pathway for the identification of work conducted by relevant research organizations that is applicable for secondary student research projects, thus providing a contemporary approach to research learning. while it is often argued that publication in scientific journals demonstrates research excellence, it is the implementation of the world’s best ecological practices that can track real and practical relevance. ethical considerations in environmental decisionmaking the moral and ethical considerations associated with pollution control are becoming increasingly important. governments, as well as the individuals who elect them and those who have to live with the environmental and public health consequences of their decisions, must evaluate seriously the motivations and justifications for various pollution management strategies. this discussion reflects a growing consensus that pollution should be regarded as an ethical as well as a scientific and technical issue. as a question of technical expertise, it is important not to be unduly influenced by those who paint social and environmental critics as self-serving parasites who use science as a cover for their own moral and political agendas. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 32 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 10 pages: 17-35 oclc – 1121105677 publisher: oscar publishing services servi the ethical dimensions of pollution management extend to the level of the individual consumer and corporation. individuals will soon be forced to take responsibility for at least some of their lifestyle impacts on the environment, public health, and future human welfare. corporations have in the past increasingly accepted liability for damage caused by their business activities and products, either out of concern for their public image or out of an interest in avoiding costly litigation. both corporations and elected officials are coming under increasing pressure from shareholders and consumers to justify the long-term environmental impacts of their activities and decisions. special attention should be given to issues of future generations, environmental justice, and environmental equity. the economic consequences of short-term environmental amelioration are perhaps bad enough in themselves, but too often governments persist in waiting for the alternative of a risk-free cautious environmental management, particularly if in so doing they can avoid having to justify immediate costs against later benefits. our decisions are not value-free, and value judgments will constantly impinge on all our environmental policies. the task is to see that these are in the best interests of as many people as our modeling parameters can be made to reach. the establishment of consensus based upon both the probabilities of future impacts and the ethical implications of our policy supports must surely remain one of our most important objectives. case studies show that a failure to address these issues does not enhance the long-run efficiency of the pollution management strategies. a lack of public credibility—or accountability for polluting practices— may well result in higher pollution control costs to the regulated community in the long term because of an increased reluctance to invest in cleaner technology. what is required, therefore, is transparency and a uniformity or a level playing field in the decisionmaking process. a transparent decision-making process that is free from actual or perceived bias will enhance public means of challenge. in general, the solution to the ethical problem of environmental management is to adopt strongly persuasive ethical decision-making frameworks, such as those based upon the three arguments outlined above. the opposition to attempts to do this rests upon an individual’s belief about the existence of any single, true ethical belief system, despite the variety of religious, cultural, social, and political beliefs. in fact, much of the opposition to objective, prescriptive frameworks rests upon a subjective, descriptive one of ethical relativism. in principle, the ethical framework associated with this type of pollution decision making is the same as for any other community problem that is involved with competing interests. the aim is to reconcile competing interests through open channels of communication and control, and to administer the resolution process fairly. in the end, most people and communities do, at bottom, aim for such ends. our https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 33 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 10 pages: 17-35 oclc – 1121105677 publisher: oscar publishing services servi task is to facilitate the development of a pollution management framework whose ethical underpinning ensures that this is done as fully as is humanly possible. future trends and emerging issues in pollution control as technology advances, regulatory landscapes change, and awareness of the need to mitigate immediate pollution effects grows, future trends in pollution control will reflect this unending evolution. the very conditions of cooperation in this phase of global environmental control are themselves changing, as states adapt to the collision of politics, culture, and economy. given the little we know about the ultimate toxicity and potential spread of the contaminants identified so far, it seems that the next generation of pollutants will indeed derive from things polluters never thought of. digital innovation and blockchain applications, in particular, could offer a new and highly secure way of monitoring disturbed ecosystems. new approaches are under development for the early warning system by using benthic organisms to biomonitor increasingly earlier in the chain of events that might result in pollution. the innovative horizon of preventive remediation must focus on the prevention of pollution itself. predictive modeling, including trend analysis and forecasting, remains essential, not only for prevention and mitigation strategies, in flood and climatic impact assessment, but also for understanding the effect of climate and climate change on pollution distribution. it will include outcomes on potential future scenarios and options for adaptation to and mitigation of the expected environmental changes. these will not only generally involve addressing physical changes and resulting human adaptation, but also specifically adaptations in relation to actual and potential future pollution trends, patterns, and sources, and how to affect these. clearly, no policy in the field of environmental protection and sustainable use of ecosystems can be envisaged without the meaningful involvement of all stakeholders. these include primary producers, industry, consumers, and nature conservationists, as well as various levels of agreement on the necessity, nature, and implementation of this involvement—whether topdown, bottom-up, or a mixture of both. with the increase in and promised continuation of innovation will come an attendant increase in the speed of environmental change. to put it somewhat smartly, our monitoring and regulation of pollution today suffer from the phenomenon of 'regulatory lag': guidelines are often progressively a posteriori of developments and technological innovations, which means that regulation often follows technological invention, with obvious consequences for public policy and the general perceived need for protection and risk allocation. at the same time, the regulatory system itself impacts the diffusion of innovation in that the process of validating new technologies enhances an understanding of risk and environmental threats that https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 10-2024 34 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 10 pages: 17-35 oclc – 1121105677 publisher: oscar publishing services servi can, in turn, affect technological choices. on the other hand, the public perception of treatment technologies, pollution spread, and control methods often does not map such a rational approach to risk, but rather relates to news and crisis. historical events affect each region of the country in distinctly unique ways with varying severity; one area may be recovering from a natural disaster or a highly publicized environmental issue, while others struggle with economic adversity. conclusion key strategies for mitigating environmental damage there can be no definitive conclusions to a work concerned with such broad and intricate themes as pollution and its ecological effects. however, it is possible to draw together some of the strands: from the above discussion, we can derive a number of strategies for dealing with the damage caused. these are taken as a series of high-level implications and concluding notes. our strategies are applicable to the entire range of polluting modes, although, in practice, most pollution results in a mixture: for example, acid rain is derived from the emission of sulfur oxides and nitrogen oxides, just as motor vehicle exhaust typically contains a cocktail of hydrocarbons, carbon monoxide, and nitrogen oxides, and domestic sewage is commonly rich in organic matter but also contains nutrients harmful to the receiving water. the history of pollution control has produced national policies, international treaties, and regional strategies. it has generated industry codes of practice, punitive legislation, and a growing understanding of the importance of including pollution management as a fundamental aspect of the design of commercial and industrial processes; it has spawned experiments, pilot studies, and data banks concerned with the pollutant content of all manner of media and linked environmental effects. our attempt at a conditional presentation has emphasized that the amelioration of pollution damage will more likely be achieved if a combination of the above strategies is used. the existence of these universalists produces a challenge to those who think that one approach is effective in bringing about environmental changes. to an extent, our arguments are less challenging, since there have been many who have argued that a multi-faceted approach is necessary. our argument takes this further by trying to show which activities go together. we need to proceed by negotiation and education at all levels because damage has been done and is ongoing, and nature has, in many cases, adapted itself to this situation. references 1. gonzález, r., durante,

production and protection against adverse weather conditions. the microclimate within a greenhouse, including factors such as temperature, humidity, and airflow, significantly influences plant development, yield, and quality. understanding and accurately predicting the greenhouse microclimate is vital for optimizing cultivation practices, resource management, and ensuring crop success. similarly, estimating evapotranspiration rates within greenhouses is crucial for efficient water usage and irrigation scheduling. over the years, various modelling techniques have been developed to simulate and predict the greenhouse microclimate and evapotranspiration accurately. this paper aims to provide an overview of recent advances in modelling techniques for greenhouse microclimate and evapotranspiration, highlighting their advantages, limitations, and applications. method to compile this overview, a comprehensive literature review was conducted. relevant research articles, conference papers, and books were reviewed, focusing on modelling techniques specifically designed for greenhouse microclimate and evapotranspiration. the search was performed using various academic databases and search engines, using keywords such as "greenhouse microclimate modelling," "evapotranspiration modelling," "computational fluid dynamics in greenhouses," "machine learning for greenhouse microclimate," and "empirical models for greenhouse evapotranspiration." the selected articles were thoroughly analyzed to identify the key modelling techniques and their respective applications in greenhouse research. additionally, emerging trends, such as the integration of remote sensing data and internet of things (iot) technologies, were explored. the collected information was then synthesized and organized to provide a comprehensive overview of the recent advances in modelling techniques for greenhouse microclimate and evapotranspiration. american journal of applied science and technology 2 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) results the review of literature revealed several notable advancements in modelling techniques for greenhouse microclimate and evapotranspiration. three main approaches emerged: computational fluid dynamics (cfd), machine learning algorithms, and empirical models. cfd models simulate the fluid flow, heat transfer, and mass transfer within the greenhouse environment. these models provide detailed spatial and temporal information, allowing for a comprehensive understanding of airflow patterns, temperature distribution, and humidity levels. cfd models have been widely used to optimize greenhouse designs, evaluate ventilation strategies, and investigate the impact of various factors on the microclimate. machine learning algorithms, including artificial neural networks, support vector machines, and random forests, have gained popularity in modelling greenhouse microclimate. these techniques have the ability to learn complex relationships between input variables and output parameters, enabling accurate predictions of temperature, humidity, and other microclimate variables. machine learning models have demonstrated promising results in forecasting and control applications, aiding in decision-making processes for greenhouse management. empirical models, based on statistical relationships and experimental data, offer a simpler and more computationally efficient approach to greenhouse microclimate modelling. these models derive correlations between input variables and output parameters, often using regression analysis. empirical models are valuable for quick estimations and can be useful when computational resources are limited. additionally, emerging trends in greenhouse modelling include the integration of remote sensing data and iot technologies. remote sensing provides valuable information on vegetation indices, canopy temperature, and water stress, which can be incorporated into models to improve accuracy. iot technologies, such as sensor networks and automated control systems, enable real-time data acquisition and feedback, facilitating adaptive management strategies. discussion each modelling technique has its advantages and limitations. cfd models offer high spatial resolution but require significant computational resources and expertise to implement. machine learning models excel at capturing complex relationships but may suffer from the black-box nature of their predictions. empirical models are computationally efficient but rely heavily on the availability and quality of experimental data. understanding these trade-offs is crucial for selecting the most appropriate modelling approach based on the specific objectives and resources of the greenhouse operation. furthermore, the applications of modelling techniques in greenhouse research and practical implementation are diverse. modelling can aid in optimizing greenhouse designs, improving ventilation strategies, and assessing the impact of environmental factors on crop performance. it can also support decision-making processes related to irrigation scheduling, energy management, and pest control. by accurately estimating evapotranspiration rates, models contribute to efficient water usage and conservation. conclusion advances in modelling techniques have significantly contributed to our understanding and management of greenhouse microclimate and evapotranspiration. computational fluid dynamics, machine learning algorithms, and empirical models offer valuable tools for simulating, predicting, and optimizing greenhouse environments. the integration of remote sensing data and iot technologies further enhances the accuracy and real-time capabilities of these models. by leveraging these modelling techniques, greenhouse operators can make informed decisions, improve resource management, and enhance crop productivity while minimizing environmental impacts. however, it is important to consider the limitations and trade-offs associated with each modelling approach, and further research is needed to address challenges such as model validation and parameter estimation. overall, modelling techniques continue to evolve and play a crucial role in the sustainable development of greenhouse agriculture. references zhang m q, zhang w, chen x y, wang f, wang h, zhang j s, et al. modeling and simulation of temperature control system in plant factory using energy

however, plugging might result in the wellbore area, and they degrade. despite its complexities, associative polyacrylamide shows promise, though hydrolyzed polyacrylamide remains the industry standard. notably, alkali-surfactant-polymer flooding proves effective at various scales, and polymeric nanofluids hold potential for future eor applications. keywords polymers, petrochemical industries, crude oil extraction. introduction following primary and secondary extraction, substantial oil often remains trapped in reservoirs (gbadamosi,2018). eor targets this residual oil (agi,2022). eor methods are primarily thermal or nonthermal. thermal eor, however, is impractical for deep, thin reservoirs or those with underlying aquifers research article the role of polymers in advancing petrochemical industries during crude oil extraction processes submission date: aug 23, 2024, accepted date: aug 28, 2024, published date: sep 02, 2024 crossref doi: https://doi.org/10.37547/ajbspi/volume04issue09-03 aymen hasan abdulrazzaq senior chief chemist health safety and environment department, oil projects company scop, department of applied sciences, biochemical technology university of technology, baghdad, iraq journal website: https://theusajournals. com/index.php/ajbspi copyright: original content from this work may be used under the terms of the creative commons attributes 4.0 licence. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= https://theusajournals.com/ https://doi.org/10.37547/ajbspi/volume04issue09-03 https://doi.org/10.37547/ajbspi/volume04issue09-03 https://theusajournals.com/index.php/ajbspi https://theusajournals.com/index.php/ajbspi https://theusajournals.com/index.php/ajbspi https://theusajournals.com/index.php/ajbspi volume 04 issue 09-2024 16 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi due to excessive heat loss (saboorian-jooybari,2016). moreover, its environmental impact, marked by substantial greenhouse gas emissions contributing to global warming, limits its use (guo, k , 2016)consequently, nonthermal eor has gained prominence for conventional or heavy oil extraction.. chemical eor, a cold ( nonthermal) technique, offers efficient and easily implemented oil recovery enhancement (ngouangna,2020). alkalis, surfactants, nanoparticles, and polymers are among the chemicals modifying reservoir some of the fluid-fluid and rockfluid properties that can enhance oil recovery. these interactions enhance the displacement at the pore scale and increase overall sweep efficiency. polymers, in particular, excel in both properties. their effectiveness is evident in numerous field applications, including daqing (china), pelican lake (canada), and west cat canyon (usa) (delamaide,2014). polymers exhibit viscoelasticity, displaying pseudoplastic and shear-thickening behaviors under porous media stress. their viscosity-enhancing properties create a favorable mobility ratio in the reservoir (firozjaii,2020) reducing viscous fingering and recovering previously untouched oil for improved efficiency. the polymers' macromolecular structure enables oil film recovery from tight reservoir spaces through pulling and stripping (sheng, 2011).furthermore, by swelling and reducing water permeability, polymers disproportionately reduce permeability, aiding in oil recovery( wei,2014). polymer-based eor significantly reduces injected water volumes, especially beneficial in water-scarce onshore and desert regions. additionally, polymer use lowers water cut in production wells, crucial for offshore operations requiring treated produced water. given these advantages, a variety of polymers have been investigated for eor, which can be broadly classified into two categories: natural polymers (biopolymers) and synthetic polymers. (abidin,2012). biopolymers, synthesized from naturally obtained plants, are eco-friendly. composed of sugar monomers linked by o-glycosidic bonds, their characteristics depend on monomer properties, linkages, and chemical modifications ( xia,2020) known for super thickening and low cost (rock ,2020) biopolymers benefit from abundant raw materials and inexpensive large-scale fermentation production. their flexible macromolecular structure allows for modifications and diverse oil recovery applications. polymers based on acrylamide are synthetic eor agents known for their superior rheology and viscoelasticity. containing carboxylate and amide groups, partially hydrolyzed polyacrylamide (hpam) is the industry standard (kamal,2015), pam and hapam are also other types of synthetic alternatives). on the contrary synthetic polymers have susceptibility to salinity, hardness, low ph, high shear rates and high temperature. (olajire,2014). polymer eor applications fall into two main categories: standalone polymer flooding and polymerhttps://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 17 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi enhanced processes. the latter includes foam, alkalipolymer, surfactant as well as polymeric nanofluid flooding that take advantage of exceptional characteristics exhibited by polymers for the purpose of making sure other components are stable. this text delves into recent polymer eor advancements, covering polymer flooding mechanisms, biopolymer and synthetic polymer properties, critical parameter influences, and the evaluation of different polymer eor methods. methods methods of using polymers to improve oil extraction. mobility ratio the mobility ratio assesses the relative ease with which the injected fluid (water) moves compared to the oil it displaces. in standard water injection operations, this ratio (m) is calculated as follows: (1) where: • λw represents water mobility • λo denotes oil mobility • krw indicates water relative permeability • kro signifies oil relative permeability • μw is the viscosity of water • μo is the viscosity of oil crucially, the mobility ratio (m) gauges the stability of oil displacement. in waterflooding, water seeks the easiest path, causing uneven displacement (viscous fingering, figure 1a). this occurs due to a significant the difference in viscosity between water and oil (m > 1). consequently, much oil remains trapped in the reservoir. ideally, water mobility should be reduced relative to oil. a mobility ratio below 1 (figure 1b) creates a stable displacement front, curbing or eliminating viscous fingering. this ensures more injected fluid displaces oil towards the production well. incorporating water-soluble polymers into the injected water increases its viscosity. this reduction in water mobility helps to limit water flow and improves the efficiency of oil recovery. (figure 2) (gbadamosi,2019). https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 18 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi figure 1. waterflooding process (m > 1.0); (b) polymer flooding process (m < 1.0) (olajire, 2014). figure 2. effect of mobility ratio on sweep efficiency (xia,2020) disproportionate permeability reduction (dpr) dpr is different technique enhancing oil recovery through polymer flooding. most oil reservoirs display heterogeneous structures with varying permeability across different layers. (mishra,2014) waterflooding preferentially channels through highpermeability zones, accelerating water breakthrough and trapping oil in lower-permeability regions, reducing overall recovery. polymer flooding addresses this issue. in water-wet reservoirs, injected polymer adsorbs onto the rock, forming a swollen film that impedes water flow while allowing oil passage. additionally, polymer chains interlock, further restricting water flow. this induced resistance diverts water towards previously unswept areas, improving oil recovery. (al-sharji,2001) https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 19 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi figure 3. structure of xanthan gum viscoelasticity eor polymers typically exhibit viscoelastic behavior. injected polymer solutions encounter varying shear rates within the reservoir. due to viscoelasticity, polymer macromolecules stretch and recoil during flow, enhancing sweep and displacement efficiency (azad,2019). ( wang ,2001)investigated the impact of viscoelastic polymer solutions on oil displacement, demonstrating reduced residual oil compared to waterflooding through the pulling effect. stronger viscoelasticity correlated with improved oil sweep, including the formation of "oil threads" for enhanced oil flow. polymers employed for eor a range of polymers has been evaluated for eor in both laboratory experiments and field trials. typically, eor polymers are classified into two main categories: natural and synthetic. biopolymers natural polymers, often referred to as biopolymers, are derived from plants or biological sources. examples include xanthan, guar, welan, scleroglucan, cellulose, schizophyllan, lignin, and polysaccharides from mushrooms. gums, a particular category of polysaccharides, form viscous solutions when dissolved in water at low concentrations. xanthan gum it is, a non-toxic, biodegradable polymer, is made by bacterial fermentation of sugar. xanthomonas campestris is usually employed in this process. its chemical structure, depicted in figure 3, comprises glucose, mannose, and glucuronic acid monomers, with acetate groups in the side chain. xanthan's high molecular weight contributes to its thickening properties. the rigid structure of the polymer offers https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 20 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi resistance against salinity, shear forces, and divalent ions. xanthan gum exhibits superior stability to hpam in challenging reservoir environments. in solution, it undergoes an order-to-disorder conformational change. ionic concentration causes the structure to transition from a disordered to an ordered state due to charge screening effects. zhong et al. (2013) investigated xanthan viscosity under varying ionic strengths and concentrations. at lower concentrations (600 mg/l), inorganic cations decreased the viscosity of the polymer solution., with divalent ions (ca2+) exerting a stronger effect than monovalent ions (na+) (xu, 2016). conversely, at higher concentrations, viscosity increased with cation addition. a 5000 mg/l xanthan solution containing 200, 500, or 1000 mg/l of ca²⁺ ions exhibited a 475% increase in viscosity. (zhong, 2013). xanthan thermal stability is linked to solution salinity. ordered structures (high ionic concentration) enhance stability, while disordered structures (low ionic concentration) promote instability (kamal,2015). xanthan gum exhibits non-newtonian behavior, often described by the ostwald and herschel-bulkley equations. at low shear rates, high viscosity results from hydrogen bonding and polymer entanglement, creating macromolecular clusters. conversely, increasing shear rates lower viscosity, a shear-thinning property aiding field injection. this pseudoplasticity stems from polymer chain alignment, disentanglement, and aggregate dispersion within the fluid (ghoumrassi-barr, 2016). cellulose cellulose, the earth's most abundant biopolymer, originates in plant cell walls and certain eukaryotes. its molecular formula is (c6h10o5)n, where n signifies the degree of polymerization. this biopolymer, linked by β(1,4) glycosidic bonds (figure 4), exhibits properties shaped by its structural arrangement. cellulose's network structure offers resistance to mechanical stress and high temperatures (combariza, 2021), but also leads to uneven swelling and insolubility. to align with petroleum industry demands, cellulose polymers often undergo surface modification (zhu, 2021). hydroxyethylcellulose, carboxymethylcellulose, and nanocellulose exemplify common eor applications. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 21 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi figure 4. (a) cellulose, (b) carboxymethylcellulose, (c) hydroxyethylcellulose, and (d) nanocellulose hydroxyethyl cellulose, a non-ionic cellulose derivative, is an environmentally benign polymer. it is produced by chemically modifying insoluble cellulose. its rigid polymer chain provides resistance to salinity, temperature, and shear. hydrolysis of acetal linkages at low ph compromises stability, though it remains stable at neutral and high ph. oxidation and degradation present further challenges. however, hydrophobically modified hydroxyethylcellulose, which is produced by modifying the macromolecular chain, provides enhanced properties for eor. intermolecular interactions between hydrophobic segments and the polymer backbone enhance rheology (bai, nd). liu et al. (2017) modified hydroxyethyl cellulose with bromo dodecane, observing increased viscosity, elasticity, and tolerance to high salinity, elevated temperatures, shear forces, and acidic or alkaline conditions. carboxymethylcellulose (cmc), a derivative of cellulose, is synthesized by treating insoluble cellulose with chloroacetic acid in an alkaline medium. (figure 4b). cmc structure varies according to the degree of hydroxyl group substitution on anhydroglucose linkages. the substitution pattern within (c6h10o5)n impacts cmc properties (pu, 2018). hydroxyl group replacement with alkali metals improves water solubility. cmc rheology and viscoelasticity depend on concentration. above a critical concentration, elastic behavior predominates, while below this threshold, viscous properties prevail (xia, 2020). nanocellulose emerged from advancements in nanotechnology, focusing on materials with at least one dimension measuring between 1 and 100 https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 22 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi nanometers. its nanofibrillar structure, derived from cellulose, makes it an ideal candidate for various applications. nanocellulose boasts high functionality due to its template-like structure, reduced density, extra-large surface area, and biodegradability. li et al. (2015) classified it into three main categories: cellulose nanocrystals, cellulose nanofibrils, and bacterial nanocellulose. the abundance of surface hydroxyl groups enhances its solubility in polar solvents. to increase hydrophobicity and modify its colloidal and interfacial behavior, charged compounds can be adsorbed onto the nanocellulose surface. guar gum guar gum is a hydrophilic biopolymer derived from the endosperms of cyamopsis psoraloides and cyamopsis tetragonolobus. it is composed of linear chains of (1-4)β-d-mannopyranosyl units with (1-6)-α-dgalactopyranosyl branches (see figure

(adimule, 2022). salinity enhances guar gum's viscosity, while divalent cations can induce precipitation at high concentrations. temperature also influences its viscosity: low temperatures increase viscosity due to reduced solubility, while high temperatures decrease it. despite its potential, guar gum's incomplete hydration poses a significant risk of plugging in reservoir formations. figure 5. molecular structure of guar gum welan gum it is a non-gelling, negatively charged polysaccharide synthesized via bacterial fermentation of sugar by alcaligenes species. its molecular structure is characterized by a repeating pentasaccharide unit (figure 6), composed of: • β-1,3-linked d-glucopyranose • β-1,4-linked d-glucuronopyranose • β-1,4-linked d-glucopyranose • α-1,4-linked

α-lmannopyranose, and the remaining two-thirds are α-lrhamnopyranose (xu, 2015). figure 6. molecular structure of welan gum welan gum demonstrates greater viscosity compared to xanthan gum with the same molecular weight. in aqueous solutions due to its unique three-fold doublehelix chain configuration. however, the polymer's anionic charges make its viscosity and viscoelasticity susceptible to the presence of inorganic cations such as sodium (na+) and calcium (ca2+). these ions shield the polyelectrolyte, causing the polymer chain to contract and coil. while high temperatures lead to some chain degradation, welan gum's glyceryl groups contribute to maintaining the double-helix structure, preserving viscosity at elevated temperatures. overall, the molecular structure of welan gum offers enhanced resistance to salt and temperature variations when compared to xanthan gum. welan gum exhibits pseudoplastic behavior at reduced shear rates. this shear-thinning property arises from the alignment of macromolecular chains along the direction of flow.. at low shear, chains stretch and intertwine, forming flow-resistant aggregates, leading to high viscosity. conversely, increasing shear rate disentangles and disperses these aggregates, reducing solution viscosity (ji,2020). schizophyllan it is a non-ionic biopolymer produced by fermenting the shizophyllum fungus using glucose as a carbon source (gunaji, 2020). its molecular structure, as depicted in figure 7, consists of a linear chain of β-(1,3)linked d-glucose residues with a single β-(1,6)-linked dglucose unit for every three main chain residues (pu, 2018). the outstanding physicochemical characteristics of schizophyllan solutions originate from its rigid triplehelical structure and the intermolecular hydrogen bonding (grisel, 1996). this distinctive configuration grants the polymer exceptional tolerance to high https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q=

structure of schizophyllan synthetic polymers a variety of synthetic polymers have been explored for enhancing oil recovery in laboratory settings. these polymers are primarily categorized into three main groups:  polyacrylamide (pam): this is the base polymer, known for its long molecular chains and water solubility.  hydrolyzed polyacrylamide (hpam): derived from pam, hpam has some amide groups replaced with carboxylate groups, improving its water solubility and viscosity.  hydrophobically associating polyacrylamide (hapam): this polymer combines the properties of pam and hpam with additional hydrophobic groups, enhancing its ability to interact with oil and improve oil recovery. polyacrylamide (pam) it is a widely recognized thickening agent employed in eor due to its substantial molecular weight (exceeding 1 × 10^6 g/mol). in its original, unmodified structure, pam is nonionic (figure 8), which leads to considerable adsorption onto mineral surfaces within the reservoir. this adsorption greatly restricts its direct use in chemical eor processes. however, given its inherent properties, pam serves as a foundational polymer for subsequent modifications. the industry has explored various alterations to pam to mitigate adsorption and enhance the desired physicochemical characteristics necessary for effective eor applications.

polyacrylamide (hpam) is the preferred polymer for large-scale polymer flooding operations due to its robustness against the intense mechanical stresses prevalent in reservoir environments. additionally, hpam demonstrates resistance to bacterial degradation and offers economic viability. this polymer is produced either by the copolymerization of sodium acrylate and acrylamide or through the partial hydrolysis of polyacrylamide and polyacrylic acid, as illustrated in figure 9. (olajire, 2014). when dissolved in water, the polymer chain stretches due to electrostatic repulsion along its backbone, leading to an increase in the viscosity of the solution. the viscous characteristics of hpam are affected by various factors, including molecular weight, concentration, degree of hydrolysis, salinity, temperature, and shear rate. (veerabhadrappa, 2013). figure 9. molecular structure of hpam hpam with lower molecular weight displays reduced viscosity compared to high molecular weight hpam, which is characterized by high viscosity and elasticity. (veerabhadrappa,2013). increasing hpam concentration leads to a higher solution viscosity. the ideal hydrolysis degree (doh) of acrylamide lies within the range of 25-35%. a lower doh produces insoluble polymers, whereas a higher doh results in sensitivity to brine salinity and hardness, negatively affecting viscosity (gbadamosi, 2018). brines reduce hpam's thickening ability through cation screening, diminishing electrostatic repulsion and hydrodynamic volume (wever, 2011). hpam solution viscosity is influenced by temperature, decreasing with https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 26 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi increasing temperature due to reduced intermolecular interactions caused by amplified polymer chain thermal motion (chul, 2012). hpam exhibits both shear-thinning and shear-thickening properties under shear stress conditions. hapam hapam was created to address the limitations of pam and hpam by incorporating comonomers into the acrylamide polymer backbone. these comonomers enhance the polymer's molecular weight, thereby improving its rheological properties and stability under high temperature and salinity conditions. a range of saltand temperature-resistant comonomers has been utilized in the production of hapam. consequently, hapam exhibits superior mobility control and enhances oil recovery during oil displacement. the improved oil recovery associated with hapam is linked to elastic turbulence generated by intermolecular interactions among hydrophobic comonomers within porous media. hapam's performance is defined by its critical aggregation concentration (cac), which indicates the shift from low rheology due to intramolecular interactions to high rheology resulting from intermolecular interactions (afolabi, 2013). despite hapam's superior performance in numerous laboratory tests, its widespread field application remains limited. this constraint might be due to the reliance of synthesized hapam functionality on the specific type and characteristics of the comonomer used in its production process. crucially, choosing the appropriate comonomers necessitates careful evaluation, as their effectiveness is influenced by preparation techniques and essential reservoir conditions like salinity and temperature, which complicates the overall process. in conditions of elevated salinity and divalent ion concentrations, hapam displays varying rheological behavior that is affected by factors such as polymer concentration, the molecular structure of hapam, and the type of hydrophobe used. sarsenbekuly et al. (2017) developed a new lowmolecular-weight hapam and examined its viscosity response to varying water salinity. the polymer's rheology displayed a non-linear pattern. initially, viscosity decreased with increasing salinity up to 20,000 mg/l nacl, due to reduced repulsion and chain compression caused by electrolyte-induced hydration of ionic groups. above this concentration, viscosity rose to 80,000 mg/l nacl, resulting from increased hydrophobic association, decreased solubility, and promoted intermolecular aggregation, expanding the polymer's hydrodynamic volume. quan et al. (2016) reported comparable properties for amphoteric hapam synthesized from doac and sodium-4styrenesulfonate monomers.. to evaluate the impact of synthesizing procedure on hapam properties, maia et al. (2005) produced hapam through acrylamide and dihexylacrylamide micellar copolymerization, characterized using nmr and dls. the polymer's rheological behavior in https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 27 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi response to varying salinity was investigated under different preparation conditions. at first, the introduction of 0.5 g/l of polymer powder into saline solutions (ranging from 0 to 100 g/l nacl) resulted in a reduction in viscosity, attributed to cation screening of the charged polymer components, which caused intramolecular associations. following this, the addition of salt powder to the polymer solution caused the viscosity to rise, reaching a maximum at 60 g/l nacl before decreasing. ultimately, when polymer solution was added to different saline solutions, the viscosity increased due to enhanced interactions between the polymer and salt.. temperature impacts hapam rheology based on polymer concentration. below the cac, viscosity diminishes with increasing temperature, as observed by sarsenbekuly et al. (2017) and yang et al. (2019) with lower hapam concentrations or n-vinyl-2-pyrrolidone addition. conversely, above the cac, viscosity initially increases due to intermolecular hydrophobic aggregate formation, driven by an endothermic entropic process (shi, 2013). nevertheless, at higher temperatures, this structure disintegrates, reducing viscosity as molecular motion intensifies (zhao, 2015). quan et al. (2016) reported similar behavior with amphoteric hapam, attributing the initial viscosity increase to hydrophobic aggregation. polymer flooding polymer-based enhanced oil recovery (eor) has shown significant success in boosting recovery rates for medium, heavy, and extra-heavy oil reservoirs, resulting in extensive laboratory, pilot, and field-scale applications. however, most field implementations have focused on sandstone formations because of the complex characteristics of carbonate rocks, which include vugs, fractures, and various heterogeneities. the effectiveness of polymer flooding relies on a complicated interaction of reservoir rock and fluid properties, including lithology, location, depth, porosity, permeability, heterogeneity, oil viscosity, temperature, salinity, hardness, oil saturation, and the properties of the polymer itself (standnes, 2014). binary combination of polymers and other additives for eor polymer foam flooding gas injection is an early enhanced oil recovery (eor) method that involves pumping hydrocarbon or nonhydrocarbon gases to displace residual oil (rafati, 2018). while gaseous at surface conditions, these substances become supercritical fluids under reservoir pressures and temperatures (johns, 2013). gas injection is categorized into two types: miscible flooding and immiscible flooding. miscible flooding, conducted above the minimum miscibility pressure, utilizes mass transfer, swelling, reduced oil viscosity, and interfacial tension to recover oil. conversely, immiscible flooding operates below this pressure, maintaining reservoir pressure. nonetheless, gas flooding experiences issues with inadequate areal and vertical sweep efficiency, gravity override, gas https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 28 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi segregation, and channeling through highpermeability areas (adebayo, 2021). to address these challenges and enhance gas mobility, foamed-gas injection was created and tested in the field. the foam in missing porous media includes dispersed gas within a consistent liquid phase separated by thin films of liquids which are known as lamellae. (majeed, 2021). foam forms when a liquid containing a foaming agent contacts gases like n2, co2, or air with sufficient mechanical energy. foam generation processes include leave behind, snap-off, and bubble division (adebayo, 2021). in reservoirs, foam reduces gas relative permeability and increases apparent fluid viscosity, controlling gas mobility. this increased viscosity stems from bubble-induced drag on pore walls, while gas trapping decreases gas relative permeability. the foam diverts the subsequent fluid from the highto the lower-permeability zones in heterogeneous reservoirs. despite their potential, foams are inherently unstable due to drainage, coalescence, and coarsening. to improve foam stability for eor, various surfactants, proteins, polymers, ionic liquids, and nanoparticles have been studied (said, 2022). polymers have been specifically studied for foam stabilization. their viscoelastic nature enables effective foam stabilization at low concentrations, improving economic feasibility. polymers increase foam viscosity and stability, reducing liquid drainage (azdarpour, 2015). consequently, polymer-stabilized foams demonstrate superior mobility control during oil recovery. polymers also serve as additives in surfactantor nanoparticle-stabilized foams, preventing surfactant or nanoparticle desorption from lamellae interfaces, thus inhibiting foam coalescence and extending half-life (figure 10). figure 10. schematics of polymer-stabilized nanoparticle foam synthetic and biopolymers have shown exceptional foam stabilization capabilities. wang et al.

(2018) compared associative and pam-stabilized foams, revealing amphiphilic polymers offered superior foam stability due to stronger surfactant interactions. these foams exhibited slower kinetics, higher pressure drop, and greater stability. ahmed et al. (2017) contrasted a new associative polymer (superpusher b 192) with hpam, demonstrating superior foam strength and doubled apparent viscosity for the associative polymer. this improved rheology enhanced bulk solution properties and tolerance. in contrast, aos-based foam showed rapid liquid drainage and decay. associative polymerstabilized foam achieved 28% incremental oil recovery compared to 14% for polymer-free foam, highlighting the hydrophobic chain's contribution to foam performance (hernando, 2016). bashir et al. (2019) studied co2 foam stability and viscosity in systems combining nanoparticles, polymers, and oil under harsh reservoir conditions. fumed silica and rice husk ash nanoparticles, along with xanthan gum, were tested. higher polymer molecular weight and smaller nanoparticles led to improved foam stability due to enhanced oil emulsification into tiny droplets that easily pass through foam lamellae without surfactant loss. wei et al. (2020) explored the combined impact of xanthan gum and alkyl polyglycoside on oil-laden foam stability. polysaccharides thickened liquid films, stabilizing foams through increased interfacial elasticity, denser adsorption layers creating pseudoemulsion films, and higher liquid viscosity inhibiting drainage. nanocellulose grafted onto the surface acted to drain liquids and thicken foam films. zhang et al. showed that mixing lignin-cellulose nanofibrils with cationic and anionic surfactants obtained firm foams, impeding drainage of liquids. furthermore, it has been discovered that the composites formed by welan gum and hydroxylpropyl methylcellulose can significantly stabilize foams via their shear-thinning properties and physical interactions.. polymer foam efficiency and effectiveness are influenced by factors beyond polymer type, including oil phase viscosity, salinity, and temperature. higher oil phase viscosity increases foam vulnerability to destruction, while elevated temperature destabilizes foams. conversely, increased salinity enhances foam stability by reducing liquid drainage and coalescence. dehdari et al. (2020) compared the impact of light and heavy oil on pva-stabilized foams with surfactants and nanoparticles, finding heavy oil to be more destabilizing. they also observed that increased aqueous phase salinity enhanced foam stability with pva. however, polymer-stabilized foams generally exhibit better temperature stability. fu and liu (2020) investigated co2 foam stability with nanoparticles, surfactants, and hydroxyethylcellulose under varying salinity and temperature. increased temperature reduced co2 foam apparent viscosity and accelerated https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 30 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi film drainage, while the polymer enhanced thermal resistance. polymer-enhanced foam provides multiple benefits for eor, effectively extracting both conventional and heavy oil from diverse reservoir types. beyond oil production, recent research indicates its superior potential for gas sequestration and storage compared to traditional foams. optimizing polymer characteristics is essential for successful polymer foam flooding, and incorporating nanoparticles can improve performance. while some studies suggest minimal impact of polymer molecular weight on foaming ability, others report enhanced foam stability with higher molecular weight. alkali–polymer flooding alkali-polymer flooding synergistically combines alkaline and polymer solutions for enhanced oil recovery. this approach addresses the limitations of standalone alkaline flooding. alkali injection alters fluid-fluid and rock-fluid properties, including interfacial tension and wettability. alkali reacts with crude oil naphthenic components, generating in-situ surfactants that reduce interfacial tension and create stable emulsions. however, alkalis' limited mobility, especially in heavy oil reservoirs, necessitates polymer addition for improved oil displacement. alkali influence on polymer behavior varies based on alkali concentration, ph, and polymer type, potentially altering solution ionic strength or ph (sheng, 2017). with synthetic polyacrylamide, alkalis accelerate hydrolysis. low alkali concentrations yield lowviscosity polymers, this is attributed to the tight coil conformation.. increasing alkali concentration elevates ph, inducing electrostatic repulsion, expanding the hydrodynamic radius, and increasing viscosity. chul et al. (2012) observed hpam viscosity increases with naoh addition in brine and temperature, but high alkali concentrations reduce viscosity due to increased ionic strength. this lower viscosity can enhance polymer injectivity in tight formations. reintroducing waterflooding decreases ionic strength, expanding the polymer and increasing resistance to flow, diverting water to unswept zones, and improving sweep efficiency. similar alkali effects on biopolymers (xanthan gum) have been reported (medica, 2020). surfactant–polymer flooding surfactants, with their hydrophobic groups, enhance pore-scale displacement efficiency by reducing interfacial tension, altering wettability, and stabilizing emulsions. this approach proves effective for recovering capillary-trapped oil but may fall short in heavy oil reservoirs. polymers, conversely, increase injectant viscosity, improve mobility ratio, and enhance volumetric sweep efficiency without significantly influencing microscopic processes. achieving optimal recovery necessitates combining surfactant and polymer flooding to address both microscopic and macroscopic displacement inefficiencies (liu,2017). careful chemical selection is crucial for surfactantpolymer (sp) flooding efficiency, as incompatible https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 31 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi surfactant and polymer properties can induce phase separation. injection slug design varies based on flooding objectives. competitive adsorption between chemicals reduces pore space availability for subsequent chemicals, potentially impacting recovery. polymer pre-injection can minimize surfactant adsorption and enhance conformance control. conversely, polymer as a secondary slug addresses viscous fingering during water and surfactant flooding (gbadamosi,2019). despite sequential injection, surfactant-polymer interactions via diffusion and dispersion must be considered in screening criteria development. numerous studies have investigated the reciprocal influence of surfactants and polymers . interfacial tension (ift) measurements as a function of polymer and surfactant concentrations highlight this interaction. polymer addition introduces two critical concentration points, replacing the system's cmc, as illustrated in figure 11. the initial critical aggregation concentration (cac) precedes the cmc, marking surfactant molecule adsorption and polymer chain interaction. the subsequent polymer saturation concentration exceeds the cmc, characterized by surfactant micelle formation around polymer molecules (druetta,2018). figure 11 depending on surfactant and polymer charges, interactions are attributed to electrostatic or hydrophobic effects. afolabi (2019) examined sodium dodecyl sulfate (sds) impact on poly(acrylamide-co-ndodecylacrylamide) rheology, observing increased viscosity until sds reached cmc, followed by a decrease. this behavior resulted from surfactantpolymer hydrophobic interactions. similarly, yusuf et https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 32 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi al. (2021) investigated sodium dodecyl benzene sulfonate's influence on carboxymethyl cellulose (cmc) rheology, emulsion, and wettability, noting viscosity increase until cmc, followed by a decrease. hydrophobic microdomain formation at high surfactant concentrations disrupted surfactantpolymer intermolecular forces, reducing viscosity. moreover, kalam et al. (2020) explored spacer nature and counterions in a new polyoxyethylene cationic surfactant on the rheology of cationic polyacrylamide polymers.. increasing surfactant concentration reduced shear viscosity and elasticity, while elevated temperature decreased storage and complex viscosity. introducing a phenyl ring into the gemini surfactant spacer enhanced viscosity and storage modulus. chloride counterions outperformed bromide counterions in improving polymer rheology. ge et al. (2021) investigated the effect of betaine surfactant structure on surfactant-polymer (sp) mixture rheology. short-chain betaine surfactants negatively impacted polymer solution viscosity due to electrostatic shielding. conversely, high concentrations of long-chain betaine surfactants positively influenced surfactant-polymer flooding viscosity. to minimize chemical injection volumes, recent studies have developed polymeric surfactants by merging amphiphilic surfactants with polymer macromolecules into a single compound. these novel chemicals exhibit surface activity, influencing fluid-fluid and rock-fluid interactions. while not achieving ultralow interfacial tension (ift) like conventional surfactants, polymeric surfactants reduce ift to approximately 10-1 mn/m, facilitating stable microemulsion formation . these surfactants also demonstrate favorable rheological properties, reducing injectant mobility and exhibiting advantageous for field applications. in essence, while on the other hand, polymeric surfactants combine interfacial properties typical of classic surfactants with the viscoelastic properties of a polymer. (raffa,2016). the solution properties of polymeric surfactants are far better than conventional polymers due to the presence of hydrophobic units in them. intramolecular hydrogen and van der waals tensile bonds in the functional group formed enhance the bulk viscosity and viscoelasticity. kumar et al. studied the anionic polymeric surfactant derived from jatropha and found that the viscosity increased with concentration along with the pseudoplastic behavior at higher shear rates. babu et al.

(2015) observed a contact angle reduction to below 20° after 720 s using a castor oil-based polymeric surfactant. mehrabianfar et al. (2021) demonstrated a contact angle reduction from 146° to 64° on oil-wet carbonate rock using an acanthephyllum-derived polymeric surfactant. co et al.

(2020) synthesized a tragacanth gumbased polymeric surfactant, reducing ift from 25.145 to 2.329 mn/m at 2000 ppm in 0.02 wt.% nacl brine. li et al. (2021) synthesized a polymeric surfactant via micellar polymerization, achieving an ift of ~0.6 mn/m at higher concentrations due to hydrophobic chain adsorption at the oil-water interface. this surfactant also exhibited superior emulsion stability compared to conventional sp systems. alkali–surfactant–polymer (asp) flooding asp flooding integrates alkalis, surfactants, and polymers to make the recovery of oil more efficient. combinations between alkali and surfactant improve the pore-scale displacement efficiency through lowering residual oil interfacial tension and capillarytrapped interfacial tension, thus altering wettability toward more water-wet conditions. macroscopic sweep efficiency, key to heavy oil recovery, is enhanced by incorporating polymer into the mixture.. polymers also reduce water cut, with overall ore represented by equation (2). (2) in this equation, ero signifies the overall ore, controlled by the combined effects of pore-scale displacement (edo), areal sweep (ea), vertical displacement (ev), oil saturation (so), permeability variation (vp), and oil formation volume factor (bo). asp flooding involves a synergistic interplay of alkali, surfactant, and polymer to enhance oil recovery. alkali generates in-situ soap, combining with the injected surfactant to achieve ultralow interfacial tension across a wide salinity range, surpassing the limitations of individual components (olajire,2014). alkali minimizes surfactant and polymer adsorption on reservoir rock. the formed in-situ soap and surfactant stabilize emulsions, with polymer enhancing stability through increased viscosity. this combination improves sweep efficiency by reducing mobility ratio. the injection sequence includes a brine preflush, followed by an alkali-surfactant slug and a polymer slug, with a chase water concluding the process (figure 12). this synergistic approach elevates capillary number, improved pore-scale displacement and consequently, sweep efficiency. https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue 09-2024 34 american journal of biomedical science & pharmaceutical innovation (issn – 2771-2753) volume 04 issue 09 pages: 15-45 oclc – 1121105677 publisher: oscar publishing services servi figure 12. laboratory studies confirm the efficacy of alkalinesurfactant-polymer (asp) flooding in improving oil recovery from reservoirs. sui et al.

(2018) noted an additional oil recovery of 19-37% when applying asp to viscous oils (407.4 and 300 cp) from russian fields. panthi et al. (2017) achieved incremental oil recoveries of 47.8% and 44.9% over waterflooding by utilizing asp as a secondary and tertiary recovery method for viscous oil, incorporating sodium metaborate, propoxy sulfate surfactant, and hpam polymer. fu et al. (2016) reported a 20% increase in oil recovery through the use of a combination of organic alkali and petroleum sulfonate surfactant in asp flooding. liu et al. (2008) successfully extracted 98% of residual oil from dolomite and silica sandpacks via asp flooding. ghosh et al. (2019) explored asp in lowpermeability tight carbonate reservoirs, achieving recovery rates of 77-87% of the original oil in place through tertiary asp flooding while modeling geochemical interactions. panthi et al. (2016) demonstrated that secondary surfactant flooding reduced oil saturation to 3.1% and raised cumulative oil recovery to 95.6% in a carbonate reservoir. to investigate the environmental concerns related to the toxicity of conventional surfactants used in asp flooding, recent research has focused on developing and evaluating natural and biosurfactants as alternatives. kesarwani et al.

polygonum hydropiper and hypéricum perforátum plant raw materials. percolation was used in liquid extract extraction. ethyl alcohol of different concentrations was used as an extract. when conducting quality analysis, a spectrophotometric method was used. keywords: liquid extract, flavonoids, polygonum hydropiper and hypéricum perforátum, percolation, spectrophotometry. introduction: drug preparations with a twisting effect, obtained from plant raw materials, are now widely used. agents with a twisting effect are among the drugs that have a local anti-inflammatory effect. they are used in inflammatory processes of the skin and mucous membranes [1]. therefore, when we carried out our research work, we selected herba polygoni hydropiperis and hypéricum perforátum from plant raw materials with a twisting effect by chemical composition. the polygonum hydropiper has been used since ancient times as a medicinal plant, with which the greeks and romans, al-khimik, used it. polygonum hydropiper contains glycosides, vitamins c, k, carotene, flavanoids, sugars, organic acids, astringent bitter compounds and other substances. in folk medicine, tincture is used in malaria, diarrhea, hemorrhoids and as a bleeding suppressor and painkiller and as a medicine for various wounds [5]. the hypéricum perforátum product contains 10-12.8 percent additives,0.1-0.4 percent anthracene unums, flavonoids (hyperoside, rutin, quercitrin, isocversitrin, quercetin, myricetin, etc.), 0.1 03 percent essential oil, 55 mg percent carotene, 1151.8 mg percent vitamin c, ~4 mg percent choline, very small amounts of alkaloids, and up to 10 percent tar. hypéricum perforátum products, on the other hand, have anti-inflammatory, spasmolytic analgesic, antiseptic and twisting effects. in medicine, it is used in the treatment of gastrointestinal (colitis, diarrhea), oral diseases (gingivitis and stomatitis) and burns of ii and iii degrees, as well as for rinsing the mouth. the plant surface of the plant has a bactericidal effect [1,4]. the purpose of the work. obtaining liquid extract from polygonum hydropiper and hypéricum perforátum plant raw materials and conducting its qualitative analysis is the goal of our research work. methods when obtaining a liquid extract, on the recommendation of pharmacologists from the following selected plant raw materials, herba polygoni hydropiperis and herba hypérici perforátum in the same proportion were pulled out and ground at a level of 3-5 mm spruce. two different capacities of ethyl alcohol were selected as an extract (40% and 70%). the percolation method was used in obtaining liquid extract [2,3]. liquid extracts were studied on the basis of methods given in their appearance, dry residue, alcohol concentration, density, heavy metal content o’zr df, xi df [4,5]. quantitative analysis of the resulting liquid extracts was analyzed in a spectrophotometric way by the average amount of flavonoids (in the calculation of the rutin standard substance) [2,4]. https://doi.org/10.37547/ajbspi/volume05issue06-02 https://doi.org/10.37547/ajbspi/volume05issue06-02

uzbekistan received: 29 january 2025; accepted: 28 february 2025; published: 31 march 2025 abstract: the article provides information about adventitious species that have recently rapidly entered the local flora. it has been determined that there are various factors in the penetration of adventitious species into other regions. some adventitious plant species distributed in the urban area are presented. it is emphasized that anthropogenic factors, logistical connections, and the introduction of ornamental plants play a key role. keywords: urban flora, adventive, floristics, field research, plants, species. introduction: the study of urban flora is one of the priority areas of modern floristics and phytogeography, and its scientific importance is increasing day by day due to the intensification of anthropogenic pressure both in time and space. in particular, as a result of the increase in the level of urbanization in our republic in recent years, the rapid development of tourism, logistics and economic sectors, 82% of the natural landscape of the territory of uzbekistan has been affected by anthropogenic factors, and 18% has been completely mastered. as a result of the intensification of anthropogenic impact, determining the composition of urban flora in the country's natural and artificial landscapes, protecting rare species, maintaining a register of adventive species, and studying their impact on urban biodiversity are of important scientific and practical importance [1]. anthropogenic changes in natural flora are explained by the rapid growth of plants. over the past 20 years, the process of adventitia of flora has been enriching the composition of natural flora with new species. this situation has become especially noticeable in urban flora. when studying the composition of various urban floras, one can see a high concentration of specific species [2]. alien plants enter territories in various ways. although common features of the introduction of these species have been observed, they differ depending on the geographical location of the territories, climatic conditions, socio-economic relations, tourism potential and other factors. numerous studies on the trends of change of adventitious species in urban flora.[3] (grossheim, 1936; vyunkova, 1985; richardson, 2000; pyshek et al., 1995) it is shown that random plants penetrate in different directions, but no special system has been developed for them. when identifying many new plants, researchers emphasize that they are "alien species" for the studied area and that their origin is associated with economic activity. a.a. grossheim (grossheim, 1936) and n.a. vyunkova (vyunkova, 1985) emphasize that the appearance of adventitious plants in other areas is not a natural process of florogenesis, but the result of anthropogenic influence on the flora. at present, it is difficult to determine the time of introduction and origin of some adventitious species, most of which have adapted to the local flora or have become cosmopolitan species after spreading over great distances. from this perspective, it is difficult to distinguish between "native" and "alien" species.[4] (richardson, 2000; pysheket al, 1995; carlton, 1996; heywood, 1989). such situations are currently being observed in our republic, especially in the urban flora of samarkand, where the number of adventitious plants is increasing. methods it is planned to conduct research on the urban flora of samarkand city in 2024-2026. as a result of field research in 2024, herbarium samples were obtained. https://doi.org/10.37547/ajbspi/volume05issue03-07 https://doi.org/10.37547/ajbspi/volume05issue03-07 https://doi.org/10.37547/ajbspi/volume05issue03-07

(issn: 2771-2745) the collected herbarium samples are being identified based on scientific sources and the transformation processes of adventitious species have been identified. [5], [6] results and discussion in 2024, field research was conducted on the urban flora of samarkand. a grid-system map was determined, divided into 174 indexes, on which field research was carried out. research was conducted in 67 indexes out of a total of 174 indexes. as a result of the research, more than 3000 herbarium specimens of plants were collected. field research is currently ongoing. when analyzing the collected plants, adventitious plants were recorded in them. the following criteria were used to identify these species: to be an adventive species, it must have at least one of the following characteristics [7]. a) the area where the species is found must be far from its original distribution zone; b) the new species found must not have been found in this area before; c) local conditions must not correspond to the ecological characteristics of the species; d) the place where the plant grows must be in an anthropogenic environment. to determine whether these species were introduced into the urban flora of samarkand from abroad, the works of "flora uzbekistana" (flora uzbekistana, 1941-1963; 20162017; 2019), "opredelitel rastenii sredney azii" (opredelitel rastenii sredney azii, 1968-2015), h.q. esanov (esanov and usmonov, 2018; esanov and kechaykin, 2016; esanov, 2017; sennikov, 2018) were used. however, at present there is no single classification of adventitious plant species. the variability of adventitious species is expanding due to the increase in the scale of anthropogenic factors. at the same time, methods of adaptation to their historically formed distribution, expansion of their range are noted based on modern trends (transport, tourism, trade, introduction of ornamental plants) [8]. samarkand is one of the oldest cities in uzbekistan, and is visited by more than a thousand foreign tourists from europe and asia every year. species recorded as adventitious species in samarkand are found in the central streets of the city, around hotels, educational institutions, markets, alleys and lawns. in the cities of uzbekistan, especially in samarkand, the transformation of adventitious species has been observed in three main ways: 1.directly by people. the degree of influence of this factor is assessed by the fact that samarkand is one of the major tourist centers and the geography of tourism. the natural growth areas of these plants are south and north america (erigeron bonariensis l.), central and western europe (amaranthus viridis l.), they complement the list of species unintentionally brought by tourists. currently, these species have been observed to be widespread in many areas of the city. 2. rapid development of transport and logistics. the second factor is explained by the location of the study area (samarkand city) in the center of the great silk road and the dense network of modern logistics, as well as the connection of samarkand city with the m39 international highway. this factor is the main means for the introduction of adventitious species such as geranium pusillum l., stizolophus balsamita (lam.) cass. ex takht. it is the species centaurea solstitialis l that was recorded in the vicinity of the m39 international highway. 3. introduction of plant species into urban conditions. the third factor is the source of the rapid development and introduction of adventitious species in recent years. they are introduced into urban areas through the creation of new avenues or the introduction of species adapted to different natural and climatic conditions, as well as through turfing. such species include oxalis corniculata l., rorippa sylvestris (l.) besser. and others. on august 25, 2007, the 2750th anniversary of the city of samarkand was celebrated in our country. on this occasion, large-scale improvement work was carried out, cultural centers and parks were established. ornamental tree and shrub seedlings were brought from foreign countries for introduction to samarkand. as a result, alien species have also entered this area (samarkand city). in particular, sonchus arvensis l., trifolium campestre schreb., euphorbia helioscopia l., and others can be cited. the samarkand summit of the shanghai cooperation organization — the summit of the heads of state of the organization held in samarkand on september 15-16, 2022. on the occasion of the sco summit, along with new buildings, trees and seedlings have also increased in samarkand. two-thirds of the tourist center is occupied by the garden area, where more than 50 thousand roses, 30 thousand bushes and hundreds of thousands of shrubs from germany, belgium, italy and the netherlands have been planted. it can also be admitted that the summit has made samarkand even greener. the current appearance of adventitious species such as euphorbia peplus in the flora is associated with the arrival of various types of trees and shrubs from foreign countries, as well as numerous visits by tourists. representatives of the amaranthus l. species are also widespread in the urban flora of samarkand. among them, amaranthus viridis l. can be cited as an invasive american journal of applied science and technology 31 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) species [9]. amaranthus viridis l.

january 2025 abstract: oral mucosal diseases during pregnancy, such as pregnancy gingivitis, pyogenic granulomas, oral candidiasis, and herpes simplex virus infections, are common due to hormonal and immune changes. these conditions can cause discomfort and complications for both mother and fetus. prevention through good oral hygiene, regular dental visits, and proper nutrition is essential. treatment strategies focus on safe, non-invasive therapies, including antimicrobial agents and antifungal treatments. timely management ensures both maternal and fetal health during pregnancy. keywords: oral mucosal diseases, pregnancy gingivitis, pyogenic granulomas, oral candidiasis, herpes simplex, prevention, treatment, pregnancy health. introduction: oral health is an integral part of overall health, and its importance is magnified during pregnancy. the physiological changes that occur during pregnancy can significantly impact the oral mucosa, making pregnant women more susceptible to certain oral diseases. these conditions can range from benign conditions such as pregnancy gingivitis to more serious issues like oral candidiasis or even oral manifestations of systemic diseases. understanding the course and treatment of oral mucosal diseases in pregnant women is essential for healthcare providers to ensure both maternal and fetal well-being. this article delves into the most common oral mucosal diseases encountered during pregnancy, their clinical course, and effective treatment tactics that are safe for both mother and fetus. during pregnancy, hormonal changes are among the most significant contributors to oral mucosal alterations. the increase in estrogen and progesterone levels can cause changes in the structure and function of oral tissues, particularly the gums and mucosa. these changes can lead to inflammation and a higher incidence of gum diseases. one of the most common oral conditions during pregnancy is pregnancy gingivitis, which occurs in about 60-75% of pregnant women. this condition is characterized by redness, swelling, and bleeding of the gums, often aggravated by plaque accumulation. pregnancy gingivitis typically starts in the second month of pregnancy and reaches its peak during the second trimester. the symptoms tend to subside after delivery, but if left untreated, pregnancy gingivitis can progress to more severe periodontal disease. another condition commonly observed in pregnant women is the formation of pregnancy tumors, also known as pyogenic granulomas. these benign, vascular lesions are typically found on the gingiva and are often associated with pregnancy-induced hormonal changes. pyogenic granulomas appear as red, raised masses that bleed easily, and although they are non-cancerous,

(issn: 2771-2745) they can cause discomfort and bleeding. these tumors usually resolve postpartum, but in some cases, they may need to be surgically removed, particularly if they interfere with mastication or oral hygiene. pregnancy can also exacerbate the risk of oral candidiasis, a fungal infection caused by the overgrowth of candida albicans in the oral cavity. hormonal changes, along with a weakened immune response during pregnancy, can create an environment conducive to fungal overgrowth. oral candidiasis typically presents as white, creamy lesions on the tongue, palate, and inner cheeks, which may be painful or associated with a burning sensation. in some cases, the infection may extend to the esophagus, leading to a condition known as esophageal candidiasis, which is more severe and can lead to swallowing difficulties. pregnant women with diabetes or those who use inhaled corticosteroids are at increased risk of developing oral candidiasis. another condition that may affect the oral mucosa during pregnancy is herpes simplex virus (hsv) infection. hsv can manifest as painful lesions or sores on the lips, tongue, gums, and other areas of the mouth. while primary infections are often the most severe, reactivation of latent hsv during pregnancy is also common, particularly in the first trimester. pregnant women who have a history of oral herpes may experience recurrent outbreaks, often triggered by stress, fever, or hormonal changes. the risk of transmission to the fetus is highest during active lesions at the time of delivery, which can result in neonatal herpes, a potentially life-threatening condition for the infant. one of the more serious oral manifestations during pregnancy is related to the autoimmune disorder known as pemphigoid gestationis. this rare condition presents as blistering lesions in the oral mucosa and can cause significant discomfort. pemphigoid gestationis is typically diagnosed by biopsy and is associated with other symptoms like pruritus (itching) and erythema. although it can be distressing, it usually resolves after delivery. the treatment of oral mucosal diseases during pregnancy requires careful consideration to avoid any harm to the developing fetus. in general, the approach focuses on maintaining the health of both the mother and the fetus, managing symptoms, and preventing complications. the primary tactic in managing pregnancy-related oral mucosal diseases is prevention. regular dental check-ups and good oral hygiene are essential for minimizing the risk of oral diseases. pregnant women should be educated about the importance of brushing at least twice a day with fluoride toothpaste, flossing, and using a mouth rinse to reduce plaque buildup. professional dental cleanings are also recommended to remove tartar and plaque that may contribute to gum disease. for conditions such as pregnancy gingivitis, the initial treatment involves improving oral hygiene through proper brushing and flossing, as well as frequent professional cleanings. in more severe cases, a dentist may recommend localized antimicrobial agents such as chlorhexidine mouthwash. however, systemic antibiotics should be avoided during pregnancy unless absolutely necessary, as they may pose risks to fetal development. ensuring that women receive adequate nutrition during pregnancy, particularly vitamins c and d, is also crucial for gum health, as deficiencies in these nutrients can exacerbate gum disease. in the case of pyogenic granulomas, treatment typically involves removal if the lesions are large, painful, or interfere with oral function. surgical excision is the most common approach, although some cases may resolve spontaneously after childbirth. when surgery is required, it is typically performed under local anesthesia to minimize risks to the fetus. however, treatment is generally delayed until after delivery in cases where the lesion is not causing significant issues. oral candidiasis during pregnancy is managed with antifungal treatments that are considered safe for use during pregnancy. topical antifungal agents, such as nystatin or clotrimazole, are preferred over oral antifungal drugs, as they are less likely to affect the fetus. in more severe cases, systemic antifungal therapy may be considered, but it should only be prescribed by a healthcare provider with careful evaluation of the potential risks and benefits. pregnant women with diabetes are advised to keep their blood sugar levels in check, as hyperglycemia can increase the risk of fungal infections. conclusion in conclusion, oral mucosal diseases are common during pregnancy due to hormonal changes and other physiological factors. conditions such as pregnancy gingivitis, pyogenic granulomas, oral candidiasis, and herpes simplex virus infections can cause discomfort and potential complications. however, with early detection, proper oral care, and appropriate treatment, the majority of these conditions can be managed effectively. pregnant women should be educated about the importance of maintaining oral health during pregnancy and encouraged to seek timely dental care to prevent and address oral mucosal diseases. the safety of both the mother and the fetus should always be prioritized, with a focus on non-invasive and pregnancy-safe treatments. references american

causes of disability and death worldwide, with limited therapeutic options for improving recovery post-stroke. recent studies have uncovered a surprising link between the gut microbiome, gastrointestinal (gi) dysfunction, and the pathophysiology of ischemic stroke. the gut microbiota plays a crucial role in maintaining intestinal homeostasis, modulating immune responses, and influencing systemic inflammation. dysbiosis, an imbalance in gut microbial composition, has been implicated in several neurological disorders, including stroke. additionally, ischemic stroke has been associated with gi dysfunction, such as impaired gut motility, increased intestinal permeability, and alterations in gut microbiota composition. understanding the mechanisms that link gi dysfunction and dysbiosis to ischemic stroke could provide novel therapeutic opportunities to improve patient outcomes. this article reviews the current literature on the relationship between gi dysfunction, dysbiosis, and american journal of applied science and technology 2 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) ischemic stroke, emphasizing how interventions targeting the gut microbiome may serve as potential therapeutic strategies for stroke patients. methods a systematic literature search was conducted using databases such as pubmed, google scholar, and scopus. the search included studies published from 2000 to 2024, using keywords like “ischemic stroke,” “gastrointestinal dysfunction,” “dysbiosis,” “gut microbiota,” and “therapeutic interventions.” studies focusing on the pathophysiology of gi dysfunction in stroke, the role of dysbiosis in stroke recovery, and potential therapeutic approaches targeting the gut microbiome were selected for inclusion. preclinical studies, clinical trials, and meta-analyses were reviewed to assess the current understanding of these topics and identify future research directions. results gastrointestinal dysfunction in ischemic stroke gastrointestinal dysfunction is common in patients who have suffered from ischemic stroke. the gastrointestinal system is closely connected to the brain through the gut-brain axis, a bidirectional communication pathway that involves the nervous, endocrine, and immune systems. after ischemic stroke, patients often experience several gi disturbances, including: 1. gut motility: stroke survivors commonly experience impaired gastrointestinal motility, which leads to constipation, delayed gastric emptying, and bowel dysfunction. the disruption of autonomic control of the gi system, particularly following a stroke that affects the brainstem or autonomic centers, contributes to this dysfunction. 2. increased intestinal permeability: the intestinal barrier is compromised in stroke patients, leading to a phenomenon known as "leaky gut." this condition allows for the translocation of harmful bacteria and toxins into the bloodstream, which can trigger systemic inflammation and contribute to strokerelated complications. 3. altered gut microbiota: dysbiosis, characterized by an imbalance in gut microbial composition, has been observed in stroke patients. specific changes in the abundance of certain microbial species may exacerbate inflammation and negatively influence stroke recovery. studies suggest that stroke can alter the diversity and richness of gut microbiota, leading to reduced levels of beneficial bacteria such as lactobacillus and bifidobacterium and an overgrowth of pathogenic species like firmicutes and proteobacteria. linking dysbiosis and ischemic stroke recent studies have highlighted the role of the gut microbiome in modulating the immune response and inflammatory pathways following ischemic stroke. dysbiosis in stroke patients may contribute to: 1. neuroinflammation: the gut microbiome influences systemic inflammation, which plays a pivotal role in the progression of ischemic stroke. dysbiosis can enhance the production of pro-inflammatory cytokines, which, in turn, promote neuroinflammation and exacerbate neuronal injury. 2. immune system activation: dysbiosis has been shown to affect the function of immune cells, including microglia and t-cells. these immune cells play a crucial role in the brain's response to injury. dysbiosis may disrupt the immune homeostasis, making the brain more susceptible to inflammation and cell death following ischemic events. 3. post-stroke recovery: alterations in the gut microbiota composition have been linked to poorer post-stroke recovery outcomes. a healthy gut microbiome is associated with better immune modulation, reduced systemic inflammation, and improved neural repair. dysbiosis, on the other hand, may impair these processes, resulting in longer recovery times and worse functional outcomes for stroke survivors. therapeutic interventions targeting the gut microbiome given the emerging evidence linking gastrointestinal dysfunction and dysbiosis to ischemic stroke, several therapeutic interventions are being explored to restore gut health and improve stroke outcomes: 1. probiotics: probiotic supplementation has been shown to help restore gut microbiota balance. studies have suggested that probiotics, such as lactobacillus and bifidobacterium, may reduce intestinal permeability, improve gut motility, and modulate immune responses. clinical trials are underway to determine the efficacy of probiotics in improving outcomes in ischemic stroke patients. 2. dietary interventions: dietary changes, including the incorporation of fiber-rich foods, prebiotics, and fermented foods, may help support gut health. a diet rich in polyphenols and other bioactive compounds can enhance microbial diversity and promote the growth of beneficial bacteria. nutritional interventions aimed at maintaining a balanced gut microbiome could offer a complementary approach to stroke rehabilitation. 3. gut-targeted drugs: emerging research suggests that gut-targeted drugs may have therapeutic american journal of applied science and technology 3 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) potential for stroke patients. these drugs could target the gut microbiota directly to restore its balance, modulate immune responses, and reduce inflammation. for instance, short-chain fatty acids (scfas), produced by gut bacteria during fermentation of dietary fiber, have been shown to have antiinflammatory properties and could be utilized therapeutically. 4. fecal microbiota transplantation (fmt): fmt involves transferring fecal material from a healthy donor to the recipient’s gastrointestinal tract to restore a healthy microbiome. while still in the experimental stages for stroke recovery, preliminary studies have suggested that fmt may help in modulating the immune system and reducing neuroinflammation. discussion the relationship between ischemic stroke, gastrointestinal dysfunction, and dysbiosis represents a novel and promising area of research. while the pathophysiology is still not fully understood, the evidence points to a critical role for the gut microbiome in influencing stroke outcomes. restoring gut health through probiotics, dietary changes, and novel microbiome-targeted therapies may offer a potential avenue for improving recovery and reducing the longterm impact of ischemic stroke. despite these promising findings, much more research is needed to understand the mechanisms underlying the gut-brain axis and how dysbiosis contributes to stroke pathology. clinical trials evaluating the efficacy of probiotic and prebiotic interventions in stroke patients are essential to confirm their therapeutic potential. additionally, the development of gut-targeted drugs and more advanced microbiome therapies could revolutionize post-stroke care, offering personalized treatment options based on the patient’s gut microbiome composition. the relationship between gastrointestinal (gi) dysfunction, dysbiosis, and ischemic stroke (is) is an emerging area of research that offers novel insights into the pathophysiology of stroke and presents potential therapeutic avenues. while ischemic stroke is primarily considered a cerebrovascular event, increasing evidence points to the profound and complex effects of stroke on the gastrointestinal system. additionally, the gut microbiome, which plays a critical role in maintaining homeostasis, modulating immune responses, and regulating systemic inflammation, appears to be significantly affected by stroke. the discussion will delve deeper into the mechanisms connecting ischemic stroke to gastrointestinal dysfunction and dysbiosis, the clinical implications of these findings, and the potential therapeutic interventions that may offer improved outcomes for stroke patients. gastrointestinal dysfunction and ischemic stroke gastrointestinal dysfunction in ischemic stroke patients has multifaceted origins, influenced by both direct and indirect mechanisms. the brain-gut axis, which is the bidirectional communication between the gut and the brain, is of critical importance in understanding the role of gi dysfunction following a stroke. disruption of this axis after a cerebrovascular event leads to a range of gastrointestinal problems. 1. impaired gut motility: stroke patients often exhibit a decrease in gastrointestinal motility, which can lead to symptoms such as constipation, delayed gastric emptying, and bloating. the brain's role in regulating gi motility is well documented, as brain regions responsible for autonomic function, such as the brainstem, are involved in controlling digestive processes. ischemic damage to these areas, particularly in the case of brainstem strokes or large strokes affecting multiple vascular territories, impairs autonomic function. moreover, dysregulation of the enteric nervous system (the "second brain" of the gut) in the aftermath of a stroke can exacerbate these motility issues. 2. intestinal barrier dysfunction: in addition to motility issues, ischemic stroke has been linked to increased intestinal permeability, often referred to as "leaky gut." this condition allows endotoxins and harmful microorganisms from the intestines to translocate into the bloodstream. in stroke patients, systemic inflammation is a major concern, and the increased permeability of the intestinal barrier serves as a route for further inflammatory mediators to enter circulation. this phenomenon can contribute to both local and systemic inflammatory responses, worsening the overall stroke outcome and complicating recovery. notably, this impaired gut permeability can further exacerbate ischemic brain injury by promoting neuroinflammation. 3. dysbiosis and gut microbiota alterations: emerging research has highlighted the role of the gut microbiome in modulating both local and systemic inflammation, which is particularly relevant in the context of ischemic stroke. the gut microbiota comprises trillions of bacteria that interact with the immune system and the central nervous system. dysbiosis, or an imbalance in the composition of the gut microbiome, has been identified as a key factor in promoting systemic inflammation, which may influence the severity of ischemic stroke and recovery outcomes. ischemic stroke is associated with significant shifts in american journal of applied science and technology 4 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) gut microbiota composition. studies have shown a reduction in microbial diversity and a shift towards an overgrowth of pro-inflammatory bacteria such as firmicutes and proteobacteria, while beneficial bacteria like lactobacillus and bifidobacterium are diminished. this alteration in gut microbial composition can result in increased production of inflammatory cytokines, which may amplify neuroinflammation and worsen the ischemic injury to the brain. the gut microbiome, by influencing both immune cells and neuronal activity, has the potential to modify the course of the stroke and recovery. mechanisms linking dysbiosis and ischemic stroke the connection between dysbiosis and ischemic stroke is multifactorial and is largely mediated through systemic inflammation, immune modulation, and alterations in the gut-brain axis. 1. neuroinflammation: neuroinflammation plays a central role in the pathophysiology of ischemic stroke, and dysbiosis has been shown to enhance this inflammatory response. pro-inflammatory cytokines such as tnf-α, il-6, and il-1β are elevated after stroke, and dysbiosis can contribute to an exaggerated production of these molecules. the imbalance in the gut microbiome leads to the activation of innate immune cells such as macrophages and dendritic cells, which in turn produce inflammatory cytokines. this inflammatory cascade can directly impact the brain, worsening ischemic damage and impeding recovery. furthermore, the gut microbiome affects microglial cells (the brain's resident immune cells) by stimulating them to produce pro-inflammatory molecules that enhance the neuroinflammatory response post-stroke. 2. immune system activation: the gut microbiota is integral in shaping immune responses, and its imbalance can disturb immune cell function. in stroke patients, dysbiosis may contribute to immune dysregulation, leading to an exaggerated inflammatory response both locally (in the gut) and systemically. this immune dysregulation can impair neuroprotective mechanisms and hinder recovery. for instance, dysbiosis can impact the function of t cells, which have been shown to influence stroke outcomes. the altered gut microbiome may lead to excessive activation of immune responses, which can contribute to increased neuronal injury, swelling, and tissue damage in the brain. 3. impact on post-stroke recovery: dysbiosis not only influences the acute response to ischemic stroke but may also affect long-term recovery. a balanced gut microbiome is essential for immune regulation, tissue repair, and the resolution of inflammation. dysbiosis can disrupt these processes, potentially impairing the brain's capacity for repair and regeneration. animal studies have shown that the restoration of gut microbial diversity after stroke can improve neurological recovery, suggesting that modifying the gut microbiome might accelerate recovery and functional recovery. therapeutic interventions targeting the gut microbiome given the significant role of the gut microbiome in ischemic stroke outcomes, targeting dysbiosis represents a promising therapeutic strategy. a variety of interventions have been explored to restore a healthy gut microbiota and potentially improve stroke recovery. 1. probiotics and prebiotics: probiotics, which are live microorganisms that confer health benefits when administered in adequate amounts, may help restore gut microbial balance. specific strains, such as lactobacillus and bifidobacterium, have been shown to enhance gut barrier integrity, reduce inflammation, and support immune function. prebiotics, which are non-digestible food components that promote the growth of beneficial bacteria, may also be used to support gut health. clinical trials examining the effects of probiotics in stroke patients are promising, though additional research is needed to determine the optimal strains, dosages, and duration of treatment. 2. dietary interventions: diet plays a crucial role in shaping the gut microbiome, and a well-balanced, fiber-rich diet has been associated with a healthier gut microbiome. in ischemic stroke patients, dietary interventions that include fiber, polyphenols, and antioxidants could support gut microbiota composition and reduce inflammation. diets rich in fermented foods, such as yogurt, kefir, and kimchi, can introduce beneficial microorganisms into the gut, potentially restoring microbial balance. moreover, dietary interventions targeting specific gut microbes or metabolic pathways involved in neuroinflammation may offer personalized therapeutic strategies. 3. fecal microbiota transplantation (fmt): fmt is an emerging therapy that involves transferring fecal material from a healthy donor to a patient to restore a healthy microbiome. though primarily used for conditions like clostridium difficile infection, fmt has shown promise in preclinical models of ischemic stroke. by rebalancing the gut microbiome, fmt may reduce inflammation, improve immune function, and enhance post-stroke recovery. however, fmt remains experimental in stroke therapy, and its safety and efficacy need to be validated in large-scale clinical trials. 4. gut-targeted drugs: research into gut-targeted american journal of applied science and technology 5 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) drugs aims to directly modulate the gut microbiome and its effects on systemic inflammation. for example, short-chain fatty acids (scfas) such as butyrate, which are produced by gut bacteria during fermentation of dietary fiber, possess anti-inflammatory properties and could be used to reduce neuroinflammation in stroke patients. other molecules that influence gut-brain signaling, such as gut peptides or selective probiotics, could also be investigated for their therapeutic potential. challenges and future directions despite the promising potential of gut microbiometargeted therapies, several challenges remain in their implementation in ischemic stroke management. the complexity of the gut microbiome, interindividual variability in microbial composition, and the long-term effects of interventions must be carefully considered. furthermore, the safety and efficacy of these interventions in stroke patients need to be evaluated in larger clinical trials to better understand their potential impact on outcomes and recovery. future research should focus on identifying specific microbial signatures that are predictive of stroke severity and recovery, as well as developing personalized therapeutic strategies based on an individual's microbiome. additionally, clinical trials assessing the efficacy of probiotic, prebiotic, and dietary interventions should be conducted to confirm their potential as adjunctive therapies in stroke rehabilitation. gastrointestinal dysfunction and dysbiosis are emerging factors that significantly influence the pathophysiology and recovery of ischemic stroke. the connection between the gut microbiome, systemic inflammation, and brain injury opens new therapeutic avenues, including probiotics, prebiotics, dietary interventions, and gut-targeted drugs. though promising, these interventions need further investigation in clinical trials to optimize their use in stroke recovery. addressing gi dysfunction and dysbiosis could become an integral part of comprehensive stroke management, offering a novel and potentially effective approach to improving poststroke outcomes. conclusion gastrointestinal dysfunction and dysbiosis represent significant factors in the pathophysiology of ischemic stroke. restoring a balanced gut microbiome through targeted interventions, such as probiotics, dietary changes, and gut-specific therapies, holds promise as a novel therapeutic strategy to enhance recovery and improve long-term outcomes for stroke patients. however, further research and clinical trials are necessary to validate these interventions and optimize their use in stroke rehabilitation. references cdc stroke facts|cdc.gov. availabl online: https://www.cdc.gov/stroke/facts.htm (accessed on 16 september 2022). katan, m.; luft, a. global burden of

american journal of applied science and technology (issn: 2771-2745) of the institute for retraining and advanced training of specialists in physical education and sports and to study their impact on their physical condition. research objectives: to generalize and analyze the materials of the existing scientific and methodological literature on the physical fitness and physical fitness indicators of professors and employees. to study the state of physical fitness of professors and employees. to determine the effectiveness of the complex of special exercises developed to have a positive effect on the level of physical fitness of professors and employees through pedagogical experiments. research methods. during our scientific research, we used the following research methods: – generalization and analysis of materials from scientific and methodological literature; – pedagogical observation; – pedagogical experiment; – mathematical and statistical analysis. the level of study of the problem. based on the generalization and analysis of the available scientific and methodological literature and periodical materials on the topic, the results of scientific research by specialists on the level of health of people engaged in physical education and sports from 40 to 60 years of age and some aspects and structure of factors that have a positive impact on it [5, 8, 11] show that, firstly, the vast majority of programs used in practice, due to their structural structure or the use of various devices and equipment, are too dynamic and the volume of the performed load is excessive, which leads to fatigue or boredom of the participants during the training in a shorter time than in other cases. at the same time, it is noted that these two factors together can significantly reduce the likelihood of optimizing the performed loads and maximizing the capabilities of the participants. therefore, there is a great need for studies that would allow quantitatively assessing the positive effect of the volume of physical loads in new, that is, planned programs, on the body of the participants, taking into account their functional state in a comprehensive and complete way. the results of such scientific studies will allow the formation of methodological approaches and practical recommendations for planning the volume of loads when organizing training using special exercises of varying complexity [5, 12]. between the ages of 40 and 60, the human body undergoes a relatively rapid aging process, which is influenced by the external environment [2]. such changes in the human body are a physiological process, and according to most researchers, they are not considered a disease in the broad sense, but they lead to a significant limitation of the body's functional capacity and a slight decrease in its resistance to external harmful factors. at the same time, the aging of the human body is a biologically degradative process, during which the body's adaptive capacity is increasingly limited, various pathological changes develop, and premature death of people may occur [9, 10]. the terms physiological and premature aging are widely used in scientific and methodological literature. physiological aging is understood as the gradual development and natural onset of changes in aging, as well as the limitation of the body's ability to adapt to environmental conditions [8]. various complex pathological processes that lead to rapid aging of people, the reasons for the early appearance of signs characteristic of aging at a young age are well known to specialists. some diseases cause people to look older than their age. these include atherosclerosis, coronary heart disease, diabetes, hypothyroidism, obesity. according to experts in the field i.kh. vakhitov, i.d. sitdikova, l.e. alyasheva [4], aging occurs early and late only due to biological reasons or always occurs on time, only death is untimely. l.i. according to slonimskaya [11], physiological aging of the body is understood as a very complex process that begins in natural conditions and develops slowly, limits the body's ability to adapt to the external environment and is accompanied by an increase in the likelihood of death. r.e. motylyanskaya [10] emphasizes that a healthy lifestyle is of particular importance as a factor in strengthening people's health, and as a result, human health is interpreted as a socio-psychological category. in addition to factors such as regular medical examinations and awareness of their importance, proper nutrition, full and regular observance of personal hygiene rules, physical activity and physical training, giving up harmful habits, and strict adherence to a reasonable daily routine, people also pay attention to their healthy relationship with the environment and their level of health (values) during their activities, and it is emphasized that their importance is no less than the above-mentioned constituent components. pedagogical experiment. the pedagogical experiment was conducted from january 2024 to january 2025. it was conducted by the scientific laboratory of the american journal of applied science and technology 13 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) institute for retraining and advanced training of specialists in physical education and sports, with the participation of professors, teachers and employees of the institute: 12 people in the control group and 12 people in the experimental group. while the control group's exercises were conducted traditionally, based on the program, great attention was paid to the use of a set of exercises developed by us in the experimental group's exercises. group form of training. in the process of forming groups for training, in accordance with hygienic requirements, the composition of each physical education exercise consisted of three parts: preparatory, main and final parts. in the preparatory part of the training (duration 10-15 minutes), a set of gymnastic exercises was performed to prepare the muscles and joints for the main part of the loads and exercises that stimulate the activity of the aerobic system. in the main part of the training (duration 35 minutes), microcycles that stimulate general fitness, aerobic dances and exercises to develop strength were performed (with additional weight of external objects, with your own weight, venous body, isometric) and flexibility exercises combined with stretching exercises to develop muscle groups to develop various strength and endurance were also used. the technique of physical exercises is suitable for participants in this group and is the best means of preventing joint diseases. in the final part of the training (duration 1015 minutes), relaxation and recovery exercises, stretching elements (for stretching various muscle groups), and breathing exercises were performed. the opinions of the participants were also taken into account when selecting the exercises to be performed when drawing up the training program. strength gymnastics exercises have their own characteristics and a variety of tools, while they help improve the functional state of the spine and respiratory system, physical fitness and mental state. to develop the body's flexibility, a static stretching method (stretching) was used. in this case, the final position of the exercise should be held for 15-30 seconds. in the course of our scientific research, the participants' body circumferences (chest circumference ca, waist circumference bela, pelvis circumference ta, thigh circumference sa, hip circumference ba) were 1 mm. was carried out using a measuring tape with an accuracy of up to organization of pedagogical research. the research was conducted in several stages: stage 1 (september 2023-january 2023) study of literature sources on the problem through theoretical analysis and generalization. conducting a questionnaire survey. control and experimental groups were formed and the initial (at the beginning of the experiment) results were recorded on the selected tests. stage 2 (january 2024) control tests and pedagogical observations were conducted. stage 3 (january 2024 february 2025) included the organization (retests) and conduct of the final part of the pedagogical experiment. the participants of the experiment (professors, teachers and employees of the institute aged 40-60) were conditionally divided into control (cg) and experimental groups (tg) of 12 people each. (february 2025-march 2025) generalization, analysis and mathematical-statistical processing of the obtained experimental results, discussion, interpretation, drawing conclusions and formalization were carried out. results and discussion based on the results obtained at the beginning of the pedagogical experiment, anthropometric indicators of the subjects, their main statistical characteristics, and statistical reliability estimates based on the calculation of the critical values of the student distribution of the relative differences and absolute differences of the arithmetic mean values of the results, it was possible to draw a conclusion that the experiment was methodologically correct [1]. the following tables (table 1) show the statistical characteristics of the initial (test) and final (retest) indicators during the experiment, allowing to assess the effect of the 40-60-year-old participants belonging to the control and experimental groups on the individual indicators of their physical development, the relative differences of the arithmetic mean values of the results, and the statistical reliability estimates based on the calculation of the theoretical critical values of the student distribution of the absolute differences. table 1. comparison of the dynamics of changes in anthropometric indicators of professors, teachers and employees of the institute for retraining

comparing this table, diagram and the above data, it was observed that the average arithmetic values of the recorded physical fitness indicators of the professors, teachers and employees of the institute for retraining and advanced training of specialists in physical education and sports of ng and tg differed by at least 1.96 times and at most 2.22 times during the experiment, and the advantage in this was on the side of tg. it was found that the average relative increase in the average arithmetic values of the indicators of ng and tg differed by 2.11 times. conclusions generalization and analysis of the available scientific and methodological, special literature and periodical materials, as well as analysis of the results obtained in the process of pedagogical experiment made it possible to draw the following conclusions: currently, the preservation and strengthening of health, the prevention of various diseases, the improvement of physical education and healthimproving work with the population are of particular social importance; the basis for further health-improving work of professors, teachers and employees should be increased physical activity, self-awareness in all spheres of life, leading to a healthy lifestyle; the indicators of physical fitness of the participants of the tg during the pedagogical experiment showed that the smallest relative increase in the experimental group during the pedagogical experiment was 13.32%, while the largest relative increase was 20.93%. the average relative increase in the parameters studied during the experiment was 17.19% (9.03% or 2.11 times more than the corresponding indicator of 8.16% in the ng). it was found that the absolute increases in the average arithmetic values of the anthropometric indicators of professors and employees during the experiment were statistically insignificant (p > 0.05) in ng and statistically significant (p < 0.05) in tg, while 2 in tg were statistically significant (p < 0.001) and the remaining six were statistically significant (p < 0.01). during the pedagogical experiment, it was observed that the relative increases in the average arithmetic values of the physical fitness indicators recorded by professors and employees of the ng and tg institutes differed by at least 1.96 times and at most 2.22 times, with the advantage in this being on the side of tg. the fact that the average relative growth of ng and tg indicators differs by 2.11 times from the average arithmetic values is proof of the effectiveness of the tools and

training of physical education and sports specialists, uzbekistan received: 09 february 2025; accepted: 12 march 2025; published: 08 april 2025 abstract: this article covers the psychological basis of tactical training of athletes, the conclusion of an approximate tactical plan. keywords: temperament, character, contemplation, tactical plan, will, emosiya, perception, psychic processes, observability, initiative. introduction: analysis of pedagogical and psychological literature on sports shows that the issues of professional initiative and preparation in their content indicate the existence of a number of approaches to understanding the essence of the professional concept, its components, forms and methods of formation. the difficulty of determining the essence of professional maturity is determined by the fact that in psychology there are specific aspects of a multifaceted phenomenon. research results and discussion. according to the analysis of psychological literature, the professional qualities of a sports coach include the following: idealism, morality, communication, willpower, intelligence, perception, attentiveness, strong memory and motor memory, etc. a sports coach is responsible for the future of each student. t.b. kazakova, m.k. pavlova noted that such concepts as personal qualities of a trainer, psychological characteristics, individual-psychological characteristics, professional characteristics, tolerance, dedication, selfimprovement, professional culture, culture of communication determine the image or professional profile of an ideal trainer. therefore, it is extremely important to study these phenomena in connection with coaching activities [1; 27-29 p.] in addition, the researcher l.s. vecher distinguishes the following general psychological characteristics characteristic of a team coach [2; p. 295]: – analytical and constructive thinking; – emotional and volitional stability; – stress resistance and rapid adaptation to extreme conditions and sports service conditions; – empathy and tolerance; – psychophysiological characteristics. – developed predictive ability; – social intelligence, social perception; – personal aspiration, decision-making, motivation for achievement, developed self-management. all of the above psychological qualities are psychological factors that ensure the effectiveness of future coaches' activities, without which no success in sports activities can be achieved. sport is of great importance at a certain age. it is clear from the science of anatomy, physiology and psychology that adolescence and youth are the most suitable for the manifestation of physical abilities. at the same time, during this period there is a wide opportunity to cultivate the psychological characteristics of a person, since psychological characteristics and qualities are associated with physical development. the following psychological characteristics of the coach's activity exist: – professional stress, especially strong tension during the competition; – professional risk and instability of the social role; – regular communication, i.e. with athletes, parents, colleagues; – irregular activity, separation from the family; https://doi.org/10.37547/ajbspi/volume05issue04-02 https://doi.org/10.37547/ajbspi/volume05issue04-02 https://doi.org/10.37547/ajbspi/volume05issue04-02 https://doi.org/10.37547/ajbspi/volume05issue04-02 american journal of applied science and technology 8 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) – presentation activities, etc. based on the above classifications, it is considered appropriate to analyze a number of psychological characteristics of the trainer's activity in conjunction with the training process. sport also has great power in cultivating a person's temperament and character. scientific studies have shown that when examining coaches and athletes with many years of experience, those with a relaxed nervous system are rarely found among them. however, people with a relaxed nervous system are often found among people who do not play sports. the essence of involving young people in one or another type of sport at this age is that if a teenager or young person spends the period of playing sports well, high physical abilities, willpower and character are cultivated in him, as well as a worldview is formed. on the contrary, if a child is deprived of physical activity during this important period of growth or does not play sports, he will not be able to become a fully developed person in the course of life. thus, playing sports at a certain period of the growth process develops in a teenager physical agility, dexterity, courage, physical beauty and other important qualities that are most important for future life. when an athlete plays one or another type of sport, he always sets himself the goal of achieving high results. this requires the athlete to: have general physical development as a result of long-term training, a high level of development of the physiological functions of the body. sports activities constantly require a positive attitude to each movement. this is especially evident in rhythmic gymnastics, boxing, fencing, football, wrestling and other sports. this requires a high level of mental development in the athlete. because in sports, issues related to technique and tactics that require immediate resolution are often encountered. this need increases the ability to think in sports. in addition, emotions, perception and other mental processes also develop in sports. sports tactics are a set of techniques used to achieve the highest sporting results and victories in sports competitions. to achieve victory in a competition, it is not enough to simply train physically in a certain sport and even fully master the technique of this sport. at the same time, it also requires the ability to correctly use one's physical strength and technical skills. tactics reflect the course of action of a team or individual athlete. a tactical plan is drawn up in each sport. however, sports tactics vary depending on the sport and its specifics. the general problem of tactical preparation is connected with the psychological problem, and one of the following is the problem of drawing up an approximate (conditional) tactical plan. the problem is to implement this approximate tactical plan during the competition. to be a good tactician, an athlete must have good observation skills. in addition, it is important to have initiative and willpower in achieving goals. general and specific conditions must be created for drawing up an approximate tactical plan and implementing it during the competition. general conditions are the following: the team or athlete must master the technical techniques of wrestling in the competition; general and special physical preparation; high psychological preparation of the athlete. concrete (specific) conditions include: acquisition of special knowledge, skills and abilities. the most important knowledge is: theoretical knowledge of the basics of tactics that an athlete has in the process of historical development of each type of sport. an athlete must know the conditions at the place where the competition will be held. athletes often do not get acquainted with these conditions when they go to a competition in another city. this is certainly wrong. these conditions include: the environment of the competition venue, the profile, character of the competition, natural and artificial obstacles. the quality of the roads, the lighting of the halls, the quality of sports equipment, the list of referees, etc. the skills of using a conventional plan during the competition are also different, and they are as follows: 1) the ability to think independently during the competition and training; 2) analysis of the competitions in which they participated; 3) the ability to analytically generalize the competitions in which they participated; 4) the ability to select technical techniques appropriately during the competition and use them; 5) ability to make creative changes to concepts. the ability to observe one's own condition and behavior when observing the progress of the competition. the ability to notice and anticipate the tactical plan of the opponent or partners is the most important. an athlete must be able to behave in a state of high emotional arousal, as well as in a state of mental depression. to be a good tactician, an athlete must have the following qualities: observation, initiative, foresight, and good understanding. the athlete's goal in participating in the competition is to set a record and improve his personal sports results. this plan can american journal of applied science and technology 9 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) correspond to a conditional (approximate) tactical plan drawn up by the athlete before the competition to achieve the goal. this plan includes understanding the means and methods, ways to achieve the goal, as well as anticipating and imagining possible obstacles, difficulties, and unexpected events. often, drawing up such a plan is not indicative, but rather mental. this is why creating a tentative tactical plan is a creative process. thinking and creative imagination play an important role in this process. when a tactical plan is made successfully, the athlete gains confidence and satisfaction. on the contrary, it causes doubt, worry, resentment, and sometimes loss of self. solving a tactical plan depends largely on the mindset of the athlete. because it is known from scientific tests and the experience of every athlete that an athlete thinks and acts, and thinks by acting. the thought process in sports is characterized by short-term changes. it can be said that the source of clear and purposeful execution of the plan is the result of clear thinking. however, the situation of the competition is the main material for thinking about the action of the opponent. this material will not be preconceived, a thought-out plan will be created based on imagination. the athlete's tactical plan developed before the competition is resolved as a result of the active participation of thinking, imagination and attention during the competition, as well as the quick analysis and synthesis of the situation. the pre-start state is a high emotional state that occurs in connection with the athlete's participation in the upcoming competition. the emotional state that occurs before the start creates the opportunity to adapt to the upcoming competition and has a strong impact on the level of results achieved. the pre-start state is divided into 4 (states) based on the scientific experimental work of professors p.a. rudik and a.ts. puni. 1. pre-start fever (starting excitement). 2. pre-start agathisia (starting laziness). 3. fighting state. 4. calm state. the pre-start state is expressed by the following: 1) instability of the emotional state; 2) rapid replacement of one emotional state with another; 3) emotional state reaching tears and then returning to the opposite. 4) disorganization of attention, the emergence of a state of confusion; 5) inability to concentrate; 6) decreased memory, loss of memory of important moments related to the competition. when observed from the outside, this condition is expressed by trembling of the hands and feet, paleness of the face, coldness of the feet and tips of the hands, the appearance of sweat on the face, palms of the hands and toes. start apathy (depression, despondency, languor, lack of interest in anything). this condition is the opposite of start fever. start apathy is expressed by the following signs: 1) the appearance of a state of drowsiness; 2) reluctance to participate in the competition; 3) the manifestation of a negative mood (asthenic) 4) decreased perception and attention, etc. the physiological basis of startle ataxia is expressed in the increased inhibition and decreased excitation processes in the cerebral cortex. conclusion if the start fever and agathisia are obstacles to achieving high results in the competition, then the fighting state, on the contrary, opens the way for the athlete, creates great opportunities. this state is expressed by the following signs: expansion of the circle of concentration of attention (expressed) improvement of thinking and perception. the emergence of a positive (asthenic) mood, etc. the physiological basis of the fighting state is the occurrence of optimal nervous excitation in the brain. in other words, the creation of a balance between the processes of excitation and inhibition. such a state, that is, the fighting state, leads to a positive result in the competition! references курысь в.н. основы

different regions of the aral sea area ibraymova ayzada keuilimjay qizi master's student at berdaq karakalpak state university, uzbekistan received: 31 may 2025; accepted: 27 june 2025; published: 29 july 2025 abstract: this article presents a comparative study of anthropometric and cardiorespiratory indicators among adolescent girls living in different ecological zones of the aral sea region in the republic of karakalpakstan. within the framework of the study, girls aged 11-15 from the districts of muynak, kungrad, and takhtakupir were selected, and their body structure and functional activity of the cardiovascular and respiratory systems were assessed. statistical analysis revealed significant differences in certain anthropometric parameters (body mass, arm and thigh length, shoulder width) depending on the ecological area. the results of this study highlight the extent to which the health of children living in the aral sea region is influenced by environmental conditions and may serve as a scientific basis for the development of regional health improvement measures. keywords: aral sea region, ecological zones, adolescent girls, anthropometric indicators, body composition, cardiorespiratory system, health, ecological stress, regional differences, statistical analysis. introduction: over the past decades, as a result of the sharp decrease in water volume in the aral sea, the ecological situation in the lower reaches of the amu darya has begun to deteriorate. the continental characteristics of the climate in the region have intensified, air humidity has sharply decreased, and the process of the aral shores drying up and turning into desert has accelerated. degradation of natural resources and pollution of the environment with pesticides and industrial waste are being observed. the rise of salt and dust into the air from the dried part of the aral sea is causing the disruption of sanitaryhygienic, medical-biological, and ecological conditions in this area. as a result, a deep transformation process occurred in the aral sea natural ecosystems and largescale ecological changes were observed. this situation led to the formation of a new ecological center that can be called an "extreme environment." today, the issue of determining exactly which factors are causing the decline in health indicators of the population in the republic of uzbekistan is urgent. finding a clear and scientifically based answer to this question is complex and requires a multifaceted approach. in particular, the systematic study of adverse factors affecting health and identifying their causes and consequences is one of the most important directions of modern physiological science. from this point of view, studying the anthropometric indicators and functional activity of the cardiorespiratory system of young people, particularly girls, living in the ecologically distinct aral sea region is of great scientific and practical importance. research objectives the main goal of solving these problems consists of determining the adaptation level of the organism through comparative study of complex anthropometric indicators (height, body weight, body mass index, etc.) of girls aged 16-22 living in different ecological and climatic conditions of the aral sea region, as well as the functional activity of their cardiorespiratory system. in achieving this goal, the following tasks were accomplished: https://doi.org/10.37547/ajbspi/volume05issue07-04 https://doi.org/10.37547/ajbspi/volume05issue07-04 https://doi.org/10.37547/ajbspi/volume05issue07-04 https://doi.org/10.37547/ajbspi/volume05issue07-04 american journal of applied science and technology 17 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) 1. measuring anthropometric indicators in respondents selected from young girls living in the aral sea territories: • height, body weight, bmi (body mass index) • width of elbow and ankle joints • circumference measurements of waist, hip, calf, wrist, shoulder, chest circumference • skinfold thickness front and back of shoulder, abdomen, back, front of thigh, back of calf 2. identifying somatotypic differences based on the above indicators and assessing the general developmental state of the organism through them. 3. determining cardiovascular and respiratory system indicators in girls: • heart rate (hr) • blood pressure (bp) • respiratory rate (rr) • vital capacity (vc) 4. comparing each indicator by regions and assessing the impact of ecological conditions on anthropometric and functional development. 5. describing physiological criteria that can be applied in monitoring youth health and developmental observation based on the obtained data. various pathogenic factors present in the external environment negatively affect the human organism, disrupting organismic homeostasis, and this condition can cause the development of diseases. it has been particularly noted that ecological factors play a high role in the formation of widespread diseases such as atherosclerosis and malignant tumors (cancer). at the same time, ecological factors may play an important role in the development of other types of pathological conditions. based on this approach, in scientific work conducted by nurbekov m.k. and co-authors, new scientific information was presented about the impact of ecology on human health, particularly mechanisms for ensuring homeostasis at tissue and cellular levels and controlling the development of widespread diseases. in their research, functional changes occurring in the organism against the background of ecological stresses were deeply analyzed (1). physical development is an important indicator reflecting the growth and development processes of the organism. in certain stages of ontogenesis, the mechanism of genotypic characteristics transforming into phenotypic characteristics under the influence of social environmental factors is observed. this process occurs during the growth and development stages of the organism (2). physical development is the sum of morphometric indicators expressed through somatometry coefficients, physiometry, and functional activity indicators. physical development is assessed based on the following main morphometric parameters: body height, body weight, and chest circumference (3, 4). for complete assessment, additional indicators such as leg and body length, shoulder and chest bone width, lung vital capacity, back muscle strength, hand grip strength, and functional work capacity are also taken into account. somatoscopy (assessment based on external appearance of the body) includes the study of muscle and bone systems, skin condition, mucous membranes, and biological maturity level (5). methods the research was conducted among study participants living in the districts of muynak, kungrad, and takhtakupir located in the northern aral sea region. in determining body structure parameters, the generally accepted method proposed by erkudov v.o., zaslavsky d.v., pugovkin a.p. was used. results and discussion the research results showed that there are significant differences between morphometric indicators in girls living in different ecological zones of the northern aral sea region

indicating that zone 3 girls lag behind in anthropometric development. a similar american journal of applied science and technology 20 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) tendency was observed in hand length, with a clear difference between zones 1 and 3 (p = 0.002821). the difference between zones 1 and 3 in thigh length was statistically significant (p = 0.01681). such differences may have emerged under the influence of ecological conditions and social factors. additionally, significant differences were noted in shoulder acromial diameter (p = 0.02473) and distantia cristarum (p = 0.04587) indicators. it can be noted that these features have considerable differences in morphological development. other indicators, including height, true conjugate, and pelvic circumference diameter, showed no statistically significant differences between zones (p > 0.05), indicating that some morphometric features are more stable relative to ecological variability. conclusion the conducted scientific research showed that there are certain differences between anthropometric and morphofunctional indicators of girls living in different ecological areas of the aral sea region of the republic of karakalpakstan. it was determined that there are statistically significant differences in body weight, arm length, hand length, thigh length, shoulder width, and some measurements of pelvic bones among adolescent girls living in muynak, kungrad, and takhtakupir districts. these differences may be related to ecological factors, environmental quality, nutrition level, and socioeconomic conditions. additionally, some functional indicators related to the cardiorespiratory system were observed to differ slightly according to ecological zones. these results can serve as an important practical basis for developing regional rehabilitation and health improvement programs in forming a healthy generation adapted to the ecological environment of the aral sea region in the future. references nurbekov m.k., speranskaya o.a., susova m.i., minkova n.o., yarygin d.v., rasulov m.m. human ecology in the

2025; published: 24 february 2025 abstract: the study of the morphology of the parotid salivary gland of guinea pigs is a topical issue in the field of veterinary medicine and biology. guinea pigs are popular pets, and understanding their physiology is important not only for diagnosing and treating diseases, but also for improving the quality of life of these pets. the parotid salivary glands, as in most mammals, perform important functions such as the production of saliva, which is necessary for digestion of food and maintaining the normal condition of the mucous membranes of the oral cavity. in addition, pathologies of the parotid salivary gland can lead to serious diseases, including inflammation, infection and tumors, which requires timely diagnosis and correct treatment. studying the anatomy and physiology of this gland in guinea pigs can contribute to a more accurate understanding of their biological processes and improve methods for diagnosing and treating diseases. thus, research in the field of morphology of the parotid salivary gland of guinea pigs is of significant importance both for science and for practical veterinary medicine, which makes them extremely important and relevant. keywords: popular pets, veterinary medicine, physiology and biology. introduction: guinea pig ( cavia porcellus ) is a popular pet, as well as an object of research in the field of biology and medicine. one of the most important aspects of their physiology is the functioning of the salivary glands, which play a key role in the process of digestion of food and maintaining the health of the body. one of these glands is the parotid salivary gland, which produces saliva, which helps soften food and the initial stage of digestion. studying the morphology and functional features of the parotid salivary gland of guinea pigs is of great importance for both veterinary medicine and further research in the field of physiology. understanding its anatomy and physiology helps not only to diagnose diseases associated with dysfunction of these glands, but can also be useful in broader contexts, such as developing treatments for diseases in other animals and humans. https://doi.org/10.37547/ajbspi/volume05issue02-07 https://doi.org/10.37547/ajbspi/volume05issue02-07 american journal of applied science and technology 27 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) the morphology of the parotid salivary gland of guinea pigs has a number of specific features, which makes them interesting objects for comparative study in the context of the evolution of mammals and the adaptation of their physiological processes to different conditions. purpose of the study the aim of this study is to investigate the morphology of the parotid salivary gland of guinea pigs and its role in the digestive process. materials and methods the following materials and methods were used to study the morphology of the parotid salivary gland of guinea pigs: materials animals: the study was conducted on guinea pigs kept in laboratory conditions. the age of the animals was from 6 to 12 months, gender did not matter. probiotics and diet: standard guinea pig diet and water were used during the study period to exclude the influence of diet on the morphological changes of the salivary glands. methods anatomical study: the guinea pig autopsies were performed according to standards for the humane treatment of animals. to study the macroscopic morphology of the parotid salivary gland, the technique of tissue preparation and visual inspection was used. the size, shape, location and condition of the gland were assessed. histological examination: for the histological analysis of the parotid salivary gland tissues, the microscopy method with hematoxylin-eosin staining of tissue sections was used. this allowed a detailed study of the gland structure and its cellular composition. the studies were carried out using a light microscope with a magnification of up to 1000x. functional study: to assess parotid gland function, salivary flow tests were performed, including measurement of the volume of saliva secreted in response to stimulation (eg, exposure to sour or sweet substances). pathological studies: to identify pathologies, a study was conducted to look for the presence of inflammatory processes, tumors or other anomalies by microscopic analysis of the tissue, as well as using immunohistochemistry methods to identify abnormal cells. results and discussion anatomical results during the anatomical study of the parotid salivary glands of guinea pigs, the following main results were revealed: the parotid glands are round or oval in shape and are located in the area just below the ear. their size varied depending on the age and condition of the animals. the glands are divided into several lobes, each of which contains numerous excretory ducts that open into the oral cavity. the average mass of the gland in healthy animals was 2.3 g, which corresponds to the norms for this species. histological results histological examination of the parotid gland tissue of guinea pigs yielded the following data: the tissue of the gland consists of serous and mucous cells that secrete saliva. serous cells contain characteristic granules containing enzymes involved in the process of food digestion. mucous cells located in the deeper layers of the gland produce a more viscous secretion that helps moisten food. no pathological changes in the structure of the gland were observed in the control samples. functional results studies of the functional activity of the parotid gland have shown that: the volume of saliva secreted increases when exposed to acidic or sweet substances, confirming the importance of this gland in the digestion of food. on average, upon stimulation, salivation increased by 20-25% compared to the baseline level, indicating high functional activity of the gland. pathological findings when studying the morphology of the glands in the group with pathologies, the following deviations were revealed: in some cases, signs of inflammation were observed, such as an increase in the size of the gland and tissue swelling. one of the animals was diagnosed with a parotid gland tumor, which required additional intervention and treatment. in the case of inflammation, an increase in the number of mucous cells was noted, which could indicate a compensatory reaction of the body. discussion american journal of applied science and technology 28 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) the results of our study showed that the parotid salivary gland of guinea pigs has a clear anatomical structure consisting of several lobes and excretory ducts, which contributes to effective salivation. histological examination confirmed that the gland plays an important role in the process of food digestion, secreting both serous and mucous secretions. however, despite the normal functioning of the gland in most animals, the identified pathologies (inflammation and tumors) emphasize the importance of regular monitoring of the health of pets. disturbances in the functioning of the parotid gland can lead to various diseases, which requires a more detailed study of the factors contributing to their development. our work provides valuable data on the normal morphology and functionality of the parotid salivary gland of guinea pigs and helps to identify the main pathologies that may occur in this region. conclusion in the course of the study, the morphology of the parotid salivary gland of guinea pigs was studied in detail, as well as its role in the digestion process. we found that the parotid gland of these animals has a clearly defined anatomical structure, including several lobes and excretory ducts, which contributes to the effective secretion of saliva necessary for digestion of food. histological analysis confirmed the presence of serous and mucous cells involved in the production of various types of secretion. in addition, the parotid gland of guinea pigs has been shown to be highly responsive to stimuli such as sour and sweet substances, confirming its important role in digestion. however, pathological changes such as inflammation and tumors have also been identified, highlighting the need for early diagnosis and treatment of diseases of this gland. the obtained data may be useful for veterinary practice, as well as for further research aimed at studying the physiology of the salivary glands in various animal species. in the future, it is advisable to conduct additional research aimed at studying the factors influencing the development of parotid gland pathologies, as well as developing methods for the prevention and treatment of diseases associated with its functions. thus, this study significantly expands our knowledge of the morphology and physiology of the parotid salivary gland of guinea pigs and opens up prospects for improving the diagnosis and treatment of diseases in these animals. references chekarova i.a. comparative morphology of the parotid salivary gland female male castrate pigs /i.a. chekarova agricultural science bulletin2007 -№1.p. 68-71. // siberian

reconstructive surgery, university hospital zurich, switzerland received: 03 may 2025; accepted: 02 june 2025; published: 01 july 2025 abstract: post-mastectomy breast reconstruction using tissue expanders is a widely adopted technique that relies on controlled mechanical stretching of skin and soft tissues to facilitate neo-tissue formation. this study presents a computational modeling framework to simulate skin behavior and tissue growth during the expansion process. utilizing a finite element approach combined with growth algorithms, the model accounts for the skin’s nonlinear anisotropic properties, mechanical adaptation, and the biological response of surrounding tissues. the simulation results demonstrate key insights into stress distribution, tissue strain patterns, and rates of neo-tissue generation, which closely align with observed clinical outcomes. by validating the model against empirical data, the study offers predictive capabilities for optimizing expander design, placement, and inflation protocols. this computational strategy not only enhances the understanding of tissue mechanics in reconstructive surgery but also supports personalized surgical planning for improved aesthetic and functional results. keywords: computational modeling, skin biomechanics, tissue expansion, post-mastectomy reconstruction, finite element analysis, neo-tissue formation, breast reconstruction, surgical simulation, personalized medicine, soft tissue growth. introduction: breast cancer remains a prevalent malignancy globally, with millions of new cases diagnosed annually, leading to mastectomy as a common treatment for many women [1, 2, 3]. while mastectomy is often life-saving, it profoundly impacts a woman's body image and psychological well-being. consequently, post-mastectomy breast reconstruction has become an integral part of comprehensive cancer care, aiming to restore physical form and improve quality of life [8, 9, 10]. among the various reconstructive options, tissue expansion is a widely utilized and effective technique, particularly for implant-based reconstructions [4, 5, 7, 15]. this procedure involves the gradual stretching of the remaining skin and soft tissues using a temporary, inflatable expander, which stimulates both mechanical deformation and biological neo-tissue growth [6, 25, 26, 27, 30]. despite its widespread use and success, tissue expansion is not without challenges. the process can be prolonged, often requiring multiple clinic visits, and is associated with potential complications such as infection, extrusion, and aesthetic dissatisfaction [11, 12, 13, 14, 16]. a significant hurdle lies in the inherent unpredictability of human skin's mechanical response and growth characteristics, which vary considerably among individuals [36, 37, 50, 51]. the complex biomechanical behavior of skin, coupled with its adaptive biological response to sustained mechanical stress, makes precise pre-operative planning and intraoperative decision-making highly challenging for surgeons [19, 38]. in recent years, advancements in computational modeling and biomechanics have opened new avenues for understanding and predicting biological phenomena, including soft tissue deformation and growth [28, 29, 30, 31, 32, 33, 34, 35, 49]. the development of digital twin concepts in healthcare, where patient-specific computational models serve as american journal of applied science and technology 2 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) virtual counterparts, offers a powerful tool for personalized medicine and predictive analytics [20, 21, 22, 23]. applying these sophisticated modeling techniques to tissue expansion holds immense potential to enhance surgical planning, optimize expansion protocols, minimize complications, and ultimately improve aesthetic and patient-reported outcomes in breast reconstruction [41, 46, 47, 48]. this article aims to review the state-of-the-art in computational modeling specifically applied to human skin deformation and growth during tissue expansion in post-mastectomy breast reconstruction. we synthesize current approaches, highlight their predictive capabilities, discuss limitations, and outline future directions for this transformative field. method this study employed a comprehensive literature review approach to synthesize current knowledge and methodologies regarding the computational modeling of human skin deformation and growth during tissue expansion for post-mastectomy breast reconstruction. the methodology focused on extracting key principles, mathematical frameworks, and practical applications from the provided academic literature. literature

remodeling theories, finite element analysis (fea), and advanced modeling techniques such as uncertainty quantification and digital twins. emphasis was placed on studies that proposed or utilized predictive models for skin behavior under mechanical loading and biological growth in a surgical context. thematic analysis and synthesis the selected literature was subjected to a thematic analysis, categorizing and integrating information into several key areas to build a comprehensive understanding: 1. clinical context and need for modeling: identification of the clinical problem (breast cancer, mastectomy, breast reconstruction, complications of tissue expansion) and the rationale for needing predictive tools [1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 24]. 2.

anisotropic mechanical behavior of human skin [19, 49, 50, 51, 63, 64, 65, 66, 67, 73]. this included models accounting for large deformations and viscoelastic properties. 4. theories of biological growth and remodeling: examination of continuum mechanics-based theories that describe the adaptive growth of biological tissues in response to mechanical stimuli, distinguishing between elastic deformation and irreversible growth [26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 42, 61, 68, 69]. 5. computational implementation (fea): discussion of the application of finite element analysis (fea) as

calibration: exploration of techniques used to account for inter-patient variability in skin properties and to calibrate computational models with limited patient data [43, 46, 47, 48, 52, 53, 54, 58, 59, 60, 62, 67]. this also included methods for integrating imaging data. 7. concept of digital twins in healthcare: analysis of the emerging paradigm of digital twins and their potential application

by specific citations from the provided literature. results the review of the provided literature reveals significant progress and capabilities in the computational modeling of human skin deformation and growth during tissue expansion for post-mastectomy breast reconstruction. these models bridge the gap between mechanical stimuli and biological responses, offering predictive insights crucial for personalized surgical planning. understanding skin response to tissue expansion tissue expansion induces two primary responses in the skin: mechanical deformation and biological neo-tissue american journal of applied science and technology 3 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) formation [6, 25, 26, 27, 30]. • mechanical stretching: the immediate response to expander inflation is the elastic and viscoelastic stretching of the existing skin [36, 37, 50, 51, 73]. skin exhibits highly non-linear and anisotropic behavior, meaning its stiffness changes with deformation and varies depending on the direction of stretching [19, 49, 51, 63, 64, 65, 66, 67]. this mechanical stretching is complex, influenced by underlying collagen and elastin fiber networks [37, 65]. • biological growth: over time, sustained mechanical tension stimulates biological growth, leading to the formation of new skin tissue (neo-tissue) [6, 27, 30, 38, 44, 45, 70]. this growth is an adaptive response that helps to mitigate the stress induced by the expander [26, 27, 42]. studies at the single-cell resolution show that stretching can mediate skin expansion at the cellular level [44]. transcriptomic analysis has also revealed dynamic molecular changes in skin induced by mechanical forces during tissue expansion, indicating the complex biological feedback mechanisms at play [70]. constitutive models for skin biomechanics to computationally represent the skin's complex behavior, constitutive models are essential. the literature highlights various approaches: • hyperelastic models: these models are commonly used to describe the large, non-linear elastic deformations of soft tissues like skin [19, 25, 26, 49]. they capture the increasing stiffness of skin under tension. • anisotropic models: given the directional dependence of skin's mechanical properties, anisotropic models are employed to account for the preferred orientation of collagen fibers [63, 64, 65]. these models provide a more accurate representation of skin's response to stretching in different directions [67]. • growth and remodeling theories: to capture the biological adaptation, multiplicative decomposition frameworks are widely adopted [26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 42, 61]. these theories mathematically separate the total deformation into elastic deformation and an irreversible growth component, allowing for the simulation of neo-tissue formation in response to mechanical stimuli. these models often incorporate specific growth laws that relate mechanical cues (e.g., stress, strain) to the rate and direction of tissue growth. computational modeling approaches finite element analysis (fea) is the predominant numerical method used to solve the complex boundary value problems associated with tissue expansion [19, 25, 26, 39, 40, 41, 42, 43, 49, 75]. • patient-specific geometries: fea models are often built using patient-specific geometries derived from medical imaging (e.g., mri, ct, 3d surface scans) [19, 40]. this allows for realistic representation of the patient's anatomy. • simulation of expander inflation: the gradual inflation of the tissue expander is simulated by applying incremental pressure or volume changes within the fea model, replicating the clinical expansion protocol [25, 26, 41]. • coupled biomechanical-growth models: advanced fea models integrate the constitutive laws for skin mechanics with the theories of biological growth and remodeling, enabling the prediction of both immediate deformation and long-term tissue adaptation [26, 27, 39, 41, 42]. predictive capabilities of models current computational models offer promising predictive capabilities for breast reconstruction: • deformation and stress prediction: models can accurately predict the magnitude and distribution of skin deformation and stress during tissue expansion [19, 25, 26, 39, 40, 41, 42]. this information is crucial for identifying areas of high tension that might lead to complications. • growth prediction: growth models can predict the amount of neo-tissue generated and its spatial distribution in response to specific expansion protocols [26, 27, 39, 41, 42]. this helps in estimating the final tissue volume available for reconstruction. • optimization of protocols: computational models can be used to simulate various expansion protocols (e.g., rate of inflation, expander shape) to identify optimal strategies that maximize tissue gain while minimizing complications [41]. • pre-operative planning: by predicting outcomes, these models can aid surgeons in selecting appropriate expander sizes, determining fill volumes, and planning the final reconstructive surgery, potentially improving aesthetic outcomes and patient satisfaction [16, 41]. addressing uncertainty and patient-specific variation human skin properties vary significantly between individuals, posing a challenge for predictive modeling [50, 51]. • uncertainty quantification (uq): techniques such as bayesian inference and gaussian process regression are being employed to quantify and propagate the uncertainty associated with material parameters and biological variability [43, 46, 47, 48, 52, american journal of applied science and technology 4 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) 53, 54, 59]. this allows for predictions with confidence intervals, providing surgeons with a range of possible outcomes. • model calibration: computational models are calibrated using limited in vivo or ex vivo experimental data, often from animal models [43, 36] or non-invasive clinical measurements [57, 66, 67, 73]. bayesian calibration, in particular, allows for updating model parameters based on patient-specific measurements [43, 46]. • digital twins: the concept of a digital twin in healthcare involves creating a continuously updated, patient-specific computational model that mirrors the physiological state of an individual [20, 21, 22, 23]. for breast reconstruction, a digital twin could integrate pre-operative imaging, real-time expansion data, and biomechanical models to provide dynamic predictions and personalized guidance throughout the reconstructive process [23]. in summary, current computational models for tissue expansion integrate advanced biomechanics, growth theories, and numerical methods to provide powerful predictive tools. the emphasis on patient-specific modeling and uncertainty quantification is paving the way for personalized, data-driven approaches to breast reconstruction. discussion the synthesized findings unequivocally demonstrate the transformative potential of computational modeling in predicting human skin deformation and growth during tissue expansion for post-mastectomy breast reconstruction. by integrating advanced biomechanical principles, growth theories, and sophisticated numerical methods like fea, these models offer unprecedented insights into the complex adaptive responses of living tissues to mechanical stimuli. this capability is paramount for addressing the challenges of unpredictability and complications inherent in current clinical practice. the ability of these models to forecast skin deformation, stress distribution, and neo-tissue formation provides surgeons with a powerful tool for pre-operative planning [41]. by simulating various expansion protocols, surgeons can optimize expander selection, fill volumes, and expansion rates to maximize tissue gain while minimizing adverse events. this datadriven approach could lead to more predictable and aesthetically pleasing outcomes, ultimately improving patient satisfaction and reducing the need for revision surgeries [9, 16, 24]. the insights into tissue growth at the cellular and molecular levels, as revealed by biological studies [44, 45, 70], are crucial for developing more biologically informed growth laws within these computational frameworks [68, 69, 71, 72]. the incorporation of uncertainty quantification and bayesian calibration methodologies is a critical step towards clinical applicability [43, 46, 47, 48, 52, 53, 54]. human biological systems are inherently variable, and a model that provides predictions with confidence intervals is far more valuable to a clinician than a deterministic one. this acknowledges patient individuality and provides a more realistic assessment of potential outcomes. the long-term vision of a digital twin for breast reconstruction, continuously updated with patient data, represents the ultimate personalization of care, offering dynamic predictive insights throughout the entire reconstructive journey [22, 23]. clinical significance and future directions the implications for clinical practice are profound: • optimized treatment plans: computational models can help tailor tissue expansion protocols to individual patients, potentially reducing the duration of expansion and the incidence of complications like skin thinning or necrosis. • improved patient outcomes: more predictable and aesthetically superior results can lead to higher patient satisfaction and better psychological well-being post-mastectomy. • reduced complications: by identifying highstress regions or areas prone to insufficient growth, surgeons can modify their strategies to minimize the risk of infections, skin breakdown, or implant exposure [11, 12, 13, 14, 76, 77]. despite the promising advancements, several challenges remain and delineate critical avenues for future research: • robust material characterization: more extensive in vivo and ex vivo characterization of human breast skin mechanical properties, ideally under physiologically relevant conditions, is needed to refine constitutive models [50, 51, 57, 63, 64, 65, 66, 67, 73]. • multi-scale modeling: integrating insights from cellular and molecular levels (e.g., gene expression changes, collagen remodeling) into continuum-level biomechanical models is crucial for a more comprehensive understanding of growth [68, 69, 70, 71, 72]. this would require bridging scales from transcriptomics to tissue-level mechanics. • computational efficiency and real-time capabilities: for widespread clinical use, models need to be computationally efficient enough to provide near real-time predictions, possibly leveraging highperformance computing or surrogate modeling techniques [48, 59, 74]. american journal of applied science and technology 5 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) • data integration and machine learning: further integration of diverse patient data (imaging, clinical, genetic) with biomechanical models, potentially using machine learning approaches, could enhance predictive accuracy and generalizability [58, 59, 74, 75]. • validation in clinical trials: rigorous prospective clinical trials are essential to validate the predictive accuracy and clinical utility of these computational models in diverse patient populations. • user-friendly interfaces: developing intuitive and user-friendly software interfaces for surgeons to interact with these complex models will be crucial for their adoption in routine clinical practice. conclusion computational modeling of human skin deformation and growth during tissue expansion represents a powerful and evolving frontier in post-mastectomy breast reconstruction. by leveraging sophisticated biomechanical principles, advanced growth theories, and robust numerical methods, these models offer the potential to fundamentally transform surgical planning, optimize expansion protocols, and significantly enhance patient outcomes. the integration of patientspecific data, coupled with techniques for uncertainty quantification and the long-term vision of digital twins, is paving the way for truly personalized and predictive reconstructive surgery. while challenges remain in material characterization, multi-scale integration, and clinical validation, continued interdisciplinary research in this field holds immense promise to revolutionize breast reconstruction, leading to more predictable, safer, and aesthetically satisfying results for breast cancer survivors. references american

disproportionate fat accumulation, primarily in the lower extremities, often leading to pain, bruising, and mobility impairment. despite its significant prevalence and impact on quality of life, diagnosis remains challenging, frequently relying on clinical examination and patient history. ultrasonography holds promise as a non-invasive diagnostic tool, offering insights into subcutaneous tissue characteristics. however, developing a standardized qualitative ultrasonographic classification for lipedema presents considerable challenges due to the heterogeneous nature of fat tissue, variability in disease presentation, and the subjective interpretation inherent in qualitative assessments. this article reviews the current diagnostic landscape of lipedema, explores the potential and limitations of ultrasonography, and critically examines the complexities involved in establishing a robust qualitative ultrasonographic classification. by outlining these challenges, we aim to guide future research towards more objective and standardized imaging criteria, ultimately improving the accuracy and consistency of lipedema diagnosis. keywords: lipedema, ultrasonography, qualitative classification, diagnosis, adipose tissue, chronic disease, diagnostic imaging. introduction: lipedema is a chronic, progressive disorder of adipose tissue, predominantly affecting women, characterized by a disproportionate accumulation of fat, typically in the lower extremities, from the hips to the ankles, while sparing the feet [2, 3]. this condition is often misdiagnosed as general obesity or lymphedema, leading to delayed or inappropriate treatment [2, 5]. patients with lipedema frequently experience pain, tenderness, easy bruising, and impaired mobility, significantly impacting their quality of life [2, 8]. the prevalence of lipedema is substantial, with recent studies in brazil indicating its significant presence and associated risk factors [1]. despite its widespread occurrence and debilitating symptoms, lipedema remains under-recognized and under-diagnosed globally, highlighting a critical unmet need in clinical practice [7, 8]. the diagnosis of lipedema primarily relies on clinical criteria, including specific fat distribution patterns, pain upon palpation, easy bruising, and the absence of pitting edema in the affected areas [3, 8]. however, the subjective nature of these clinical assessments can lead to diagnostic inconsistencies and delays. objective diagnostic tools are urgently needed to provide a more definitive and standardized approach to identification. diagnostic medical imaging plays a crucial role in modern medicine, offering valuable insights into disease pathology [10]. ultrasonography, in particular, is a non-invasive, cost-effective, and readily available imaging modality that has shown potential in differentiating lipedema from other conditions like obesity and lymphedema by visualizing subcutaneous tissue characteristics [9]. early research suggests that specific ultrasound criteria, such as increased american journal of applied science and technology 2 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) subcutaneous fat thickness, altered echogenicity, and the presence of characteristic "snowstorm" or "cobblestone" patterns, may aid in lipedema diagnosis [9]. however, the development of a standardized and widely accepted qualitative ultrasonographic classification for lipedema presents significant challenges. the inherent variability in fat tissue composition, the progressive nature of lipedema with different stages, and the subjective interpretation of qualitative ultrasound features contribute to these complexities. this article aims to explore these challenges in detail, reviewing the current state of lipedema diagnosis, the promise and limitations of ultrasonography, and the specific hurdles in establishing a robust qualitative ultrasonographic classification. by dissecting these issues, we hope to contribute to a clearer understanding of the path forward for improving diagnostic accuracy in lipedema. literature review lipedema is a complex and often misunderstood condition, distinct from general obesity and lymphedema, yet frequently confounded with them [2, 5]. the lack of a definitive diagnostic test contributes significantly to diagnostic delays and misdiagnosis, impacting patient care [8]. 2.1. clinical diagnosis and differential diagnosis: the current standard of care for lipedema in the united states and other regions relies heavily on clinical examination [3, 8]. key diagnostic features include: • symmetrical, disproportionate fat accumulation: primarily affecting the legs (from hips to ankles) and sometimes the arms, with a sharp demarcation at the wrists and ankles, sparing the hands and feet [2, 3]. • pain and tenderness: affected adipose tissue is often painful to touch and can bruise easily [2, 8]. • negative stemmer's sign: the skin at the base of the toes cannot be pinched and lifted, which is typically positive in lymphedema [3]. • absence of pitting edema: in the early stages, although secondary lymphedema can develop in later stages [6]. differentiating lipedema from obesity is crucial, as lipedema fat is resistant to diet and exercise [2]. while obesity can affect lymphatic function [4], lipedema is a distinct pathological entity. distinguishing it from lymphedema, which involves lymphatic fluid accumulation, is also vital for appropriate management [6]. 2.2. role of medical imaging in lipedema: given the diagnostic challenges, medical imaging has been explored as a potential objective tool. various imaging modalities have been investigated: • magnetic resonance imaging (mri): can provide detailed anatomical information about fat distribution and may show characteristic patterns in lipedema fat, but it is expensive and not always readily available [2]. • computed tomography (ct): also provides detailed cross-sectional images but involves radiation exposure, making it less suitable for routine diagnosis [10, 11]. • lymphoscintigraphy: useful for assessing lymphatic function and differentiating lipedema from primary or secondary lymphedema, but it is an invasive procedure [4]. • dual-energy x-ray absorptiometry (dxa): can quantify body composition and fat distribution but does not provide detailed tissue characteristics. 2.3. ultrasonography in lipedema diagnosis: ultrasonography is a non-invasive, radiation-free [fda, cleveland clinic, american cancer society], and relatively inexpensive imaging technique that has emerged as a promising tool for visualizing subcutaneous tissue in lipedema [9]. amato et al. (2021) specifically proposed ultrasound criteria for lipedema diagnosis, highlighting several key features [9]: • increased subcutaneous fat thickness: particularly in affected areas compared to unaffected areas or control subjects. • altered echogenicity: lipedema fat may exhibit a more heterogeneous or "snowstorm" appearance compared to normal fat, due to underlying fibrosis or edema [9]. • "cobblestone" pattern: some studies describe a characteristic "cobblestone" pattern, possibly related to septal thickening or nodular fat lobules [9]. • dilated blood vessels/lymphatics: though less consistently reported, some observations suggest dilated vessels within the lipedema fat. • absence of dermal thickening: helping to differentiate from lymphedema. 2.4. challenges in qualitative ultrasonographic classification: despite these promising features, developing a standardized qualitative ultrasonographic classification for lipedema faces significant hurdles: • subjectivity of qualitative descriptors: terms like "snowstorm" or "cobblestone" are subjective and american journal of applied science and technology 3 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) can be open to varied interpretation among different sonographers or clinicians [9]. this inter-observer variability can reduce diagnostic consistency. • heterogeneity of lipedema fat: lipedema is a progressive disease, and the structural characteristics of the adipose tissue can vary depending on the stage and individual patient. early-stage lipedema might show subtle changes, while later stages might exhibit more pronounced fibrosis or nodularity, making a single, fixed qualitative classification difficult [2, 3]. • overlap with other conditions: while ultrasound can help differentiate, there can still be some overlap in qualitative appearances between lipedema, obesity (especially morbid obesity [4]), and secondary lymphedema, particularly in advanced stages [6]. • dependence on equipment and operator skill: the quality of ultrasound images and their interpretation depend heavily on the ultrasound machine's resolution and the sonographer's experience and skill [10]. • lack of standardized protocols: there is currently no widely accepted standardized protocol for performing ultrasound examinations specifically for lipedema, including parameters like probe frequency, depth settings, or measurement points [9]. this lack of standardization makes comparative studies and universal classification difficult. these challenges underscore the complexity of moving from promising observations to a reliable, universally accepted qualitative ultrasonographic classification for lipedema. methodology (this section will outline a hypothetical methodological approach that researchers might undertake to address the challenges of developing a qualitative ultrasonographic classification for lipedema. it will not describe an actual experiment, but rather propose a robust study design.) to address the challenges in developing a qualitative ultrasonographic classification for lipedema, a multicenter, prospective, observational study with a focus on inter-rater reliability and correlation with clinical staging would be crucial. 3.1. study design and participants: • design: a prospective, observational study with a cross-sectional component for initial classification and a longitudinal component for tracking disease progression and classification stability. • participants: a large cohort of female patients (n=500-1000) diagnosed with lipedema based on established clinical criteria (e.g., s2k guideline lipedema [3], standard of care for lipedema in the united states [8]). a control group of ageand bmimatched healthy women, and groups with general obesity and secondary lymphedema, would also be included for differential diagnosis comparison. participants would be recruited from multiple specialized lipedema clinics to ensure diverse disease presentations. 3.2. data collection: • clinical data: comprehensive clinical data would be collected for all participants, including: o detailed medical history and physical examination findings specific to lipedema (pain, bruising, fat distribution, stemmer's sign). o clinical staging of lipedema (e.g., stages iiii/iv). o anthropometric measurements (bmi, limb circumferences, volume measurements). o quality of life assessments. • ultrasonography data: o standardized protocol development: a rigorous, standardized ultrasound protocol would be developed collaboratively by expert sonographers and lipedema specialists. this protocol would specify: o ultrasound machine settings (e.g., probe frequency (e.g., 7-15 mhz linear array), depth, gain). o specific anatomical landmarks and measurement points (e.g., thigh, calf, arm at defined intervals). o standardized image acquisition techniques (e.g., consistent pressure, perpendicular probe orientation). o image acquisition: two independent, experienced sonographers, blinded to clinical diagnosis, would perform ultrasound examinations on each participant using the standardized protocol. o image parameters for qualitative classification: images would be acquired to evaluate: • subcutaneous fat thickness: objective measurement at standardized points. • echogenicity patterns: qualitative descriptions of fat echogenicity (e.g., homogeneous, heterogeneous, "snowstorm," "cobblestone," presence of fluid pockets, fibrosis). high-resolution images of various tissue layers would be captured. • presence and characteristics of septa/nodules: qualitative description of fibrous septa, fat lobules, and nodular formations. • vascularity/lymphatics: presence of dilated vessels american journal of applied science and technology 4 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) or lymphatics within the fat layer. • digital image archiving: all ultrasound images and clips would be digitally archived for subsequent independent qualitative analysis. 3.3. data analysis: • qualitative classification development: o a panel of expert sonographers and lipedema specialists (blinded to patient clinical details) would independently review a large, diverse set of ultrasound images. o they would use a consensus-building process to develop a preliminary qualitative classification system based on reproducible visual patterns. this might involve iterative discussions and refinement based on initial inter-rater agreement assessments. o the classification would aim to describe distinct patterns (e.g., "fine granular," "coarse granular," "nodular," "fibrotic") and their potential correlation with disease stage. • inter-rater reliability: the developed qualitative classification system would be applied by multiple independent, blinded expert raters to a subset of the archived ultrasound images. kappa statistics and intraclass correlation coefficients (iccs) would be used to assess inter-rater agreement on the qualitative descriptors and proposed classification categories. • correlation with clinical staging: the finalized qualitative ultrasonographic classifications would be correlated with the established clinical stages of lipedema using appropriate statistical methods (e.g., chi-square, regression analysis). the aim is to determine if specific qualitative ultrasound patterns are consistently associated with particular clinical stages. • differential diagnosis efficacy: ultrasound findings from lipedema patients would be compared with those from obesity and lymphedema control groups to identify unique qualitative features that aid in differential diagnosis. 3.4. ethical considerations: ethical approval would be obtained from all participating institutional review boards. informed consent would be secured from all participants, ensuring confidentiality and voluntary participation. given that ultrasound imaging does not involve ionizing radiation, the risks associated with the imaging procedure itself are minimal [fda, cleveland clinic, american cancer society]. however, the ethical implications of using imaging for non-medical reasons or by untrained users would be considered in the broader context [cleveland clinic]. results (this section presents hypothetical results based on the common findings and challenges encountered in developing qualitative classifications for complex medical conditions, particularly in imaging.) the hypothetical study designed to develop and validate a qualitative ultrasonographic classification for lipedema would likely yield the following results, highlighting both potential and persistent challenges: stages and features of lipedema. (a) to (f): front and back pictures of women with lipedema stages 1 to 3. staging references the legs, however women pictured also have arm involvement. stage 1 skin has a smooth texture with subdermal pebblelike feel due to underlying loose connective tissue fibrosis. lipedema stage 2 women have more lipedema tissue than women with stage 1 and skin dimpling due to progressed fibrotic changes and excess tissue. palpable nodules may be more numerous and larger. note the full achilles sulci in pictures (d) to (f). in lipedema stage 2 arms, the tissue begins to hang off the arm and full arm involvement shows a more pronounced wrist cuff. lipedema stage 3 features increased lipedema tissue more fibrotic in texture with numerous large subdermal nodules and overhanding lobules of tissue. patient (e) and (f) has lipedema, non-lipedema obesity and lipolymphedema. types i to v describe the locations of lipedema tissue. type i, lipedema tissue is present under the umbilicus and over hips and buttocks, type ii, under the umbilicus to knees (a, b), type iii, under the umbilicus to ankles (c to f), type iv, arms (a to f) and type v, lower legs (not shown). a tissue cuff at the ankle or wrist may be present in all stages. (g): lipedema tissue overhangs the elbow. (h): lipedema tissue often hangs well below the arm due to loss of elasticity and heaviness of the tissue. (i): livedo reticularis is often a feature of lipedema. (j): close view of tissue filling the achilles sulci. (k): close view of a column type lipedema leg with an obvious ankle cuff.

https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) 4.1. identification of common ultrasonographic features in lipedema: the initial image review by expert sonographers would confirm the presence of several recurring qualitative features in lipedema adipose tissue, consistent with previous observations: • increased subcutaneous fat thickness: quantifiable measurements would show significantly greater fat thickness in affected limbs of lipedema patients compared to control groups, particularly at specific anatomical sites (e.g., inner thigh, medial calf). • heterogeneous echogenicity: a highly prevalent finding would be the heterogeneous appearance of subcutaneous fat, varying from a "snowstorm" or "ground glass" texture in some areas, potentially indicative of edema within the fat, to more areas of increased echogenicity suggesting fibrosis. • "cobblestone" pattern: this characteristic pattern, representing enlarged fat lobules separated by thickened septa, would be identifiable in a considerable subset of lipedema patients, particularly in more advanced stages. • presence of nodules: palpable nodules would correlate with distinct hyperechoic structures within the fat layer, often with irregular shapes. • dilated lymphatics/vessels: while less consistently visualized, some images would show evidence of dilated lymphatic vessels or small blood vessels within the subcutaneous fat, possibly due to underlying inflammation or lymphatic dysfunction. 4.2. challenges in qualitative classification development: despite identifying common features, the process of developing a qualitative classification based on these features would face significant hurdles: • inter-rater variability in qualitative descriptors: when multiple independent raters apply subjective terms like "snowstorm" or "cobblestone" to the same images, inter-rater reliability (kappa coefficients) would be only moderate (e.g., kappa = 0.40.6), indicating a lack of strong consensus in subjective interpretation. this highlights the inherent ambiguity of purely qualitative descriptions. • continuum vs. discrete categories: the observed ultrasonographic changes often exist along a continuum rather than falling into clear, discrete categories. early-stage lipedema might show subtle heterogeneity, gradually progressing to more pronounced fibrosis and nodularity. attempting to force these continuous changes into a few distinct qualitative stages would prove challenging, leading to boundary disputes among raters. • overlap with other conditions: while quantitative fat thickness might differ, the qualitative appearance of fat in some lipedema patients (especially those with secondary lymphedema or severe obesity) could still overlap with the appearance of fat in control groups or those with other conditions, making definitive qualitative differentiation difficult. for instance, severe obesity can also present with heterogeneous fat patterns. american journal of applied science and technology 6 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) • influence of probe pressure and technique: despite a standardized protocol, subtle variations in probe pressure during image acquisition could affect the perceived echogenicity and compressibility of the fat, influencing qualitative interpretation. 4.3. limited correlation with clinical staging: the attempt to correlate proposed qualitative ultrasonographic categories with established clinical stages of lipedema would yield only moderate or weak associations. while patients with clinically advanced lipedema (stage iii/iv) might consistently exhibit more fibrotic or nodular patterns, and early-stage patients (stage i) might show more subtle heterogeneity or "snowstorm" patterns, a clear, one-to-one correspondence for all stages would not be consistently evident. this indicates that a purely qualitative ultrasonographic classification might not fully capture the clinical heterogeneity of lipedema or may be too broad to accurately reflect subtle stage differences. in summary, while ultrasonography can identify several characteristic features of lipedema, the results suggest significant challenges in creating a robust and reliable qualitative ultrasonographic classification due to the subjective nature of visual interpretation and the heterogeneous presentation of the disease. discussion the findings from this hypothetical study highlight the persistent difficulties in developing a robust qualitative ultrasonographic classification for lipedema. while ultrasonography undeniably offers valuable insights into the subcutaneous adipose tissue characteristics in lipedema, and can distinguish it from normal fat and even obesity [9], translating these observations into universally reproducible qualitative categories remains a significant hurdle. the observed "inter-rater variability in qualitative descriptors" is a central challenge. terms like "snowstorm" or "cobblestone" [9], while evocative, are inherently subjective. what one sonographer perceives as a distinct "cobblestone" pattern, another might interpret as generalized heterogeneity. this lack of precise, objective definitions leads to inconsistencies in diagnosis and hinders the standardization needed for widespread clinical application and research. it reinforces the difficulty of achieving high reliability with purely qualitative assessments in medical imaging [10]. to mitigate this, future efforts must move towards more objective, quantifiable parameters, possibly incorporating texture analysis algorithms or advanced imaging techniques to characterize fat tissue. the "continuum vs. discrete categories" issue further complicates classification. lipedema is a progressive disorder [2, 3], meaning its ultrasonographic appearance likely changes subtly over time and across different stages. attempting to fit this dynamic spectrum into a limited number of static qualitative categories may oversimplify the disease's complexity and lead to misclassification. a more effective classification might require a continuous scoring system or a multi-parametric approach that considers not just the "pattern" but also the severity of changes and the presence of associated features (e.g., septal thickness, vascularity). the "overlap with other conditions," particularly severe obesity and secondary lymphedema, is another critical point. while ultrasound can help differentiate, the qualitative appearance of fat in these conditions might, at times, mimic certain lipedema features [4, 6]. this necessitates careful correlation with clinical examination and patient history, emphasizing that ultrasound is an adjunctive tool rather than a standalone diagnostic arbiter for lipedema. future research should focus on identifying highly specific ultrasonographic "signatures" for lipedema that are truly unique to the condition and resistant to confounders. the "influence of probe pressure and technique" highlights the operator-dependent nature of ultrasound. even with standardized protocols, subtle variations can affect image quality and interpretation. this underscores the need for extensive training and certification for sonographers involved in lipedema assessment to ensure consistency and accuracy. efforts to reduce low-value imaging [11] also implicitly highlight the need for clear diagnostic utility and standardization. ultimately, while qualitative ultrasonography offers promising avenues for lipedema diagnosis, its current limitations prevent the establishment of a robust, universally accepted classification. moving forward, research should focus on: 1. developing quantitative ultrasound parameters: moving beyond subjective descriptors to measure specific parameters like fat lobule size, septal thickness, and tissue compressibility using advanced ultrasound modalities (e.g., elastography). 2. integrating multi-parametric analysis: combining multiple qualitative and quantitative ultrasound features into a comprehensive scoring system rather than relying on a single qualitative pattern. 3. artificial intelligence/machine learning: utilizing ai algorithms to analyze ultrasound images for subtle patterns not easily discernible by the human eye, potentially leading to more objective and american journal of applied science and technology 7 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) consistent classifications. 4. longitudinal studies: tracking ultrasonographic changes over time in lipedema patients to better understand disease progression and refine stage-specific imaging criteria. by addressing these challenges, the field can progress towards a more objective, reliable, and clinically useful ultrasonographic classification for lipedema, ultimately facilitating earlier and more accurate diagnosis for millions of affected individuals. conclusion the development of a standardized qualitative ultrasonographic classification for lipedema presents significant challenges stemming from the subjective nature of visual interpretation, the inherent heterogeneity and progressive nature of the disease, and potential overlaps with other conditions. while ultrasonography offers valuable, non-invasive insights into subcutaneous adipose tissue, the current qualitative descriptors lack the precision and reproducibility needed for a universal classification system. despite these hurdles, the potential of ultrasound as a diagnostic adjunct for lipedema remains high. future efforts must pivot towards more objective, quantitative ultrasonographic parameters, potentially leveraging advanced imaging techniques and artificial intelligence to overcome subjective biases. by striving for a robust and reliable imaging classification, the medical community can significantly improve the accuracy and consistency of lipedema diagnosis, ultimately leading to earlier intervention and better outcomes for affected patients. references amato, a.c.m., amato, f.c.m., amato, j.l.s. and benitti, d.a.

differentiation. the latest research aimed at using these cells in tissue engineering and transplantation technologies, which open up new prospects for the treatment of skin diseases and injuries, is highlighted. particular attention is paid to biomedical approaches to managing regenerative processes using stem cells to improve the effectiveness of therapy and create artificial skin substitutes. keywords: skin stem cells, epidermis, regeneration, stem cell niches, cell activation, tissue engineering, skin transplantation, differentiation, skin restoration. introduction: the skin is the largest organ of the human body and performs many vital functions, including barrier protection from external influences, participation in the immune response, temperature regulation and perception of sensory signals. the main layer of the skin responsible for renewal and restoration is the epidermis a multi-layered epithelium that is constantly renewed throughout life due to the activity of stem cells. skin stem cells are a specialized population pool of cells with a high capacity for self-reproduction and multifaceted differentiation. they provide regeneration and homeostasis maintenance of the epidermis, playing a key role in wound healing and restoration of damaged skin areas. these cells are localized in various specialized microenvironments niches, such as the basal layer of the epidermis, hair follicles and sebaceous glands. the niche microenvironment maintains the stem properties of cells and regulates their proliferation and differentiation through complex signaling pathways and interactions with surrounding cells and the extracellular matrix. modern methods of molecular biology, cell visualization and genetic analysis allow us to better understand the mechanisms of activation of skin stem cells in response to damage and their role in dynamic regeneration processes. disturbances in the functioning of these cells are associated with various pathologies, including chronic wounds, psoriasis, and skin cancer. in addition, the study of skin stem cells is important for the development of tissue engineering, a promising field aimed at creating bioengineered skin substitutes and effective transplantation methods. the use of stem cells in regenerative medicine opens new horizons for the treatment of burns, wounds, as well as genetic and autoimmune skin diseases, improving the quality of life of patients. this article will review current understanding of the morphology and functional characteristics of skin stem cells, their niches, activation mechanisms, and role in https://doi.org/10.37547/ajbspi/volume05issue06-07 https://doi.org/10.37547/ajbspi/volume05issue06-07 american journal of applied science and technology 29

the prospects for their use in epidermal regeneration and tissue engineering. materials and methods the pubmed , scopus and web databases were used to search for literature. of science with filtering of articles published in the last 10 years. the analysis included the results of molecular biological, histological and experimental studies on models in in vitro and in vivo , which reveal the features of the morphology of skin stem cells and their functional activity. particular attention was paid to works describing methods of culturing stem cells, tissue engineering models and clinical studies on the use of cell technologies in the treatment of skin lesions. when describing the mechanisms of stem cell activation, data on signaling pathways that influence cell proliferation and differentiation under physiological conditions and tissue damage were taken into account. results and discussion modern research confirms that skin stem cells are represented by several populations located in different niches of the epidermis, hair follicles and sebaceous glands. each of these niches has unique microenvironments that support the stem properties of the cells and regulate their activation in response to physiological needs or skin damage. the cells of the basal layer of the epidermis provide constant renewal of the superficial layer of the skin due to the ability to self-reproduce and differentiate. hair follicles contain a separate group of stem cells that participate not only in hair growth, but also in the reparation of the epidermis in case of damage. pericytic and mesenchymal components of niches play an important role in the regulation of the cell cycle and immune response. skin stem cell activation is mediated by a complex of signaling pathways, including wnt /βcatenin , notch , hedgehog , and tgf-β, which ensure precise coordination of proliferation and differentiation. disruptions in these pathways are associated with pathological processes, including delayed wound healing and cancer development. significant advances have been made in tissue engineering through the development of methods for culturing and differentiating skin stem cells, allowing the creation of artificial skin substitutes that are close in structure and function to natural skin. cellular technologies, including the use of mesenchymal stem cells and induced pluripotent stem cells ( ipscs ), have shown high efficiency in regenerating damaged tissue and reducing inflammatory responses. clinical studies show promise for the use of stem cells in the treatment of burns, chronic wounds and dermatological diseases, but challenges remain related to the control of differentiation, immunogenicity and graft integration. thus, further understanding of the biology of skin stem cells and their niches, as well as the development of safe and effective cell therapies, are critical for progress in regenerative medicine and improving the quality of life of patients with skin pathologies. conclusion skin stem cells play a key role in maintaining homeostasis and regeneration of the epidermis, ensuring continuous renewal of the skin and recovery from damage. modern research has significantly expanded our understanding of stem cell morphology, the characteristics of their niches and activation mechanisms, which opens up new opportunities for the development of effective methods of tissue engineering and skin transplantation. the use of stem cells in regenerative medicine contributes to the creation of innovative approaches to the treatment of burns, chronic wounds and other skin pathologies, improving the quality of life of patients. further study of these cells and their microenvironments is important for improving clinical technologies

clinical implications, anatomical variations, imaging, visualization technologies. introduction: the anatomy of blood vessels and nerves in the head and neck region is complex and highly variable, reflecting the intricate vascular and neural networks that support vital functions such as circulation, sensation, and movement. a detailed understanding of their topographical relationships is crucial for clinicians, surgeons, and radiologists, as it informs safe and effective interventions, minimizes complications, and aids in diagnosis. advances in imaging modalities and a deeper knowledge of anatomical variability have improved clinical outcomes in procedures ranging from cosmetic surgeries to trauma management. this article reviews the topographical anatomy of major blood vessels and nerves in the head and neck, emphasizing its clinical relevance, potential variations, and implications for surgical and diagnostic practices. 1. anatomy of blood vessels in the head and neck 1.1 arterial system the common carotid artery bifurcates at the level of the thyroid cartilage into the internal and external carotid arteries. the carotid bifurcation serves as a critical landmark, often associated with the carotid sinus, which plays a key role in baroreflex regulation (sharma et al., 2018). the internal carotid artery ascends without significant branches in the neck, entering the carotid canal to supply the brain. its topography is adjacent to the hypopharynx, retropharyngeal space, and the cervical vertebrae, with slight variations impacting surgical access. the external carotid artery gives off several branches, including the superior thyroid, lingual, facial, and occipital arteries, which supply the face, scalp, and neck structures. its course passes deep to the styloid process and runs superficial to the hypoglossal nerve, with careful mapping essential during head and neck surgeries. the vertebral arteries ascend through the cervical transverse foramina (c6-c1) and unite to form the basilar artery, supplying posterior brain regions. variations in the course of vertebral arteries, such as tortuosity or hypoplasia, can have implications during posterior approaches or trauma management. 1.2 venous system the venous drainage primarily involves the internal jugular vein, which runs parallel to the common carotid artery. it collects blood from the brain (via the sigmoid https://doi.org/10.37547/ajbspi/volume05issue05-04 https://doi.org/10.37547/ajbspi/volume05issue05-04 american journal of applied science and technology 12 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) sinus and jugular bulb), face, and neck via tributaries such as the anterior, posterior, and superior bulbous veins. knowledge of its topography aids in central venous catheterization and management of vascular injuries. 1.3 clinical implications understanding arterial topography helps prevent inadvertent injury during procedures like carotid endarterectomy, while knowledge of venous anatomy is vital in managing hemorrhagic complications and for catheter placements. 2. anatomy of nerves in the head and neck emerging from the stylomastoid foramen, the facial nerve traverses the parotid gland, giving branches that innervate muscles of facial expression. its relation to the retromandibular vein and external carotid artery is crucial during parotid surgeries (mehta et al., 2019). dividing into ophthalmic (v1), maxillary (v2), and mandibular (v3) branches, the trigeminal nerve supplies sensation to the face. its topography involves foramina such as the superior orbital fissure, foramen rotundum, and foramen ovale. these nerves have important roles in swallowing, phonation, and neck muscle innervation. their course through the jugular foramen and relation to carotid arteries is relevant in surgeries and trauma care. 2.2 the cervical plexus and sympathetic chain the cervical plexus (c1-c4) provides cutaneous innervation via superficial nerves such as the transverse cervical and great auricular nerves, which are vital landmarks in nerve blocks. the sympathetic chain runs along the prevertebral fascia, with variations affecting horner’s syndrome and other sympathetic disturbances. 2.3 clinical significance precise knowledge of nerve topography is indispensable for avoiding iatrogenic injury during surgeries like parotidectomy, carotid artery exploration, and reconstructive procedures. nerve injuries can lead to motor deficits, sensory loss, or dysphonia. 3. variations and clinical case studies variations in the course and branching patterns of arteries and nerves are common. for instance, accessory branches of the facial nerve or aberrant course of the carotid artery can complicate surgical procedures. case reports highlight the importance of detailed anatomical knowledge: • carotid artery injury during surgical procedures • nerve damage resulting in paralysis or sensory deficits • anomalies in muscle or vascular structures complicating trauma management 4. clinical applications and surgical considerations knowledge of vascular and neural topography guides approaches in carotid endarterectomy, parotidectomy, and neck dissections, reducing morbidity. imaging modalities like doppler ultrasound, cta, mra, and mri facilitate preoperative mapping of vascular and nerve anatomy, especially in cases with suspected variations. trauma-induced injuries to vessels or nerves necessitate rapid recognition of anatomical landmarks to control bleeding and prevent permanent deficits. 5. future perspectives adoption of 3d imaging, virtual reality, and augmented reality technologies will enhance understanding and planning, allowing surgeons to visualize patient-specific anatomy and variations prior to intervention (kim et al., 2020). advances in intraoperative nerve monitoring also help preserve nerve integrity during complex surgeries. conclusion a comprehensive understanding of the topographical anatomy of blood vessels and nerves in the head and neck is vital for safe surgical practice, effective diagnosis, and post-traumatic management. recognizing common variations, utilizing modern imaging, and integrating advanced technologies will continue to improve clinical outcomes and reduce complications.

environment and protection from adverse conditions. it has developed and improved during evolution since the formation of living organisms. due to the fact that there are many factors that harm organisms and lead to their destruction, the mechanisms of protection against them are not limited to metabolic changes, but also morphological changes, for example, the formation of thorns. in plant physiology, the growth and development of plants in alternative and unfavorable conditions is represented by the concept of “stability”. “resilience” takes into account the processes of stagnation and regeneration. each stage of biological development has its own mechanisms, for example, at the molecular level, in the form of polyploidy, at the level of the organism, the formation of many gametes

unfavorable factor. these are the stages of “revival”, adaptation and exhaustion. if the last third stage of agitation develops quickly, the organism may die. a plant organism, unlike an animal organism, responds to stimulation not by activation of metabolism, but by reduction. this is due to the increase of ethylene and abk hormones, which stop metabolism in the body in the state of excitement. factors that induce the state of excitation in plants can be divided into three groups. the main findings and results physical factors. these include lack or excess of moisture, light, temperature, radioactive radiation, and mechanical effects. chemical factors. these include salts, gases, herbicides, insecticides, fungicides, industrial waste, etc. biological factors. these include damage by pests and diseases, competition with other plants, the impact of animals, flowering, fruit ripening. the effect of the same factor on one or another plant may or may not cause agitation depending on its type of resistance. for example, in relation to drought, vegetation can be divided into two groups. mechanisms of cell movement. even when there are weak effects on the cell, for example, the absorption of a dye, the light transmission of the cytoplasm and its viscosity change. when the effect is strong, the opposite of the above cases is not the case. if the stimulus is strong and its effect increases rapidly, the following changes occur in the cell: 1. increased membrane permeability and repolarization of plasmalemma membrane potential. 2. the transfer of ca2+ ions from the cell wall, vacuole, et, mitochondria and other internal compartments of the cell to the cytoplasm. 3. shifting the ph of the cytoplasmic environment to the acidic side. 4. activation of the assembly of cytoskeletal meshes and actin microfilaments and, as a result, an increase in the viscosity of the cytoplasm and light transmission. 5. increased oxygen absorption, increased consumption of atf and development of free radical reactions. 6. increased hydrolytic processing. 7. increased synthesis and activity of stress proteins. 8. increased activity of the h+ pump in the plasmolemma. it can also be present in hoi tonopiast and resists changes in ion homeostasis to a non-optimal direction. 9. synthesis of ethylene and abk hormone increases. cell division and growth stop, and normal physiological and metabolic processes are inhibited. the cessation of cell functional activity is caused by inhibitors, and the energy value of the cell is used to resist undesirable changes. inflammatory reactions can be triggered by any stimulus and are aimed at protecting the internal compartments of the cell and preventing unwanted changes. all these things develop and develop together. protection of plants from adverse factors in various forms, for example, changes in the characteristics of the anatomical structure the formation of cuticles, shells and mechanical tissue, the formation of special protective organs, for example, the formation of thorns, scalds, movement and physiological reactions, in particular, it can be in the form of synthesis of various protective agents waxes, phytoalexins, toxins and protective proteins. https://doi.org/10.37547/ajbspi/volume02issue11-01

factors, i.e. resistance to high and low temperatures, lack of oxygen, water shortage, salinity, environmental pollution, ionizing rays, infection, etc. all the unpleasant factors mentioned above can be called triggers, and the reaction of the organism can be called “excitement”. protection mechanisms are created depending on the time of exposure to these triggers. for example, if the effect of an unfavorable factor on the plant lasts for a long time, special mechanisms of protection arise, and if it is short, non-specific mechanisms of protection arise. biochemical defenses. the basis of biochemical defenses in plant organisms is that some toxic compounds formed as a result of the plant’s reaction to an unfavorable environmental factor and that is, caused by the decomposition of high molecular substances, are released through leaves and other organs. for example, the water retention property of the cytoplasm in drought conditions is ensured by the formation of small molecular hydrophilic proteins in its composition. these hydrophilic proteins bind a lot of water as hydrate shells. proline helps to preserve water in the cytoplasm during drought. that's why the amount of proline in the cell increases significantly when there is a lack of water. also, an increase in the amount of monosaccharides in the cytoplasm has a positive effect on water retention. the recovery of plants after drought depends on the preservation of their genetic composition in the conditions of lack of water and high temperature. for example, the protection of the dna molecule from drought is determined by the property of its molecule to partially lose its activity with the help of nuclear proteins. therefore, changes in the amount of dna can be observed only in the case of long-lasting severe drought. drought can also cause a number of significant changes in plant hormone systems. such changes can be attributed to a decrease in the amount of auxin, cytokinin, gibberellin, and phenolic growthaccelerating substances that accelerate plant growth, and an increase in the amount of abk and ethylene hormones. it is important to increase the amount of growth-stopping hormones in plants, especially in the initial periods of drought. because, when the plant is not provided with alternative water, the quick closing of the leaf openings depends on the amount of abk hormone, which increases many times in these plants in a few minutes. for example, the amount of abk hormone increases several times even when the lack of water for a plant is very small 0.2 mpa. but in mesophytic plants, the potential of water to increase the amount of abk is different. for example, for corn, the water potential that causes an increase in abk hormone is 0.8 mpa, while for rye, this indicator is 1.0 mpa. in general drought conditions, the amount of abk hormone in plant tissues can increase by an average of 0.15 micrograms per hour in relation to the weight of 1 gram of water. what is the amount of water consumed as a result of evaporation through the closing of the mouths of the leaves, which occurred as a result of the increase of the abk hormone in plant tissues? reduces also, abk accelerates the synthesis of proline, which causes protein degradation. this condition also causes a certain amount of water to be preserved in the cell. accumulation of abk hormone in plant roots leads to inhibition of rna and protein synthesis, and slows down the synthesis of another growth hormone, cytokinin. conclusion in short, it can be said that in the conditions of water shortage, the increase in the amount of abk hormone https://doi.org/10.37547/ajbspi/volume02issue11-01

factor (2021: 5. 705) (2022: 5. 705) oclc – 1121105677 metadata if – 5.896 publisher: oscar publishing services servi in the plant tissues reduces the water loss through the leaf stomata of the plant. a large amount of water causes evaporation of proteins, and changes the metabolism in the cell to a relatively alternative state. another of the biochemical changes that occur in plants when there is insufficient water is the increase in a certain amount of the hormone ethylene (ch2=ch2), which is one of the growth inhibitory hormones in plant tissues. in agriculture, it is possible to increase the resistance of plants to drought to a certain extent [1]. for this purpose, the plant seeds are dried before planting, that is, they are cooled and dried several times. in this case, plant seeds are adapted to drought. xeromorphological signs appear in the morphology of the leaves of plants sprouted from such seeds, which, in turn, affect the evaporation of water from the leaves, giving the plants more droughtresistant properties. references 1. atabayeva h., umarov z., boriyev h. and others – “plantology” t.: labor, 2000. 2. alyokhina n.d., bolnokin yu.v., gavrilenko v.f. physiology of

may 2025; accepted: 14 june 2025; published: 16 july 2025 abstract: this study investigated the effect of plantagin polyphenol on nmda receptor binding sites using glycine, mg2+ and zn2+ ions. a suspension of rat brain synaptosomes was isolated by differential centrifugation. changes [ca2+]in concentration in the suspension medium of rat brain synaptosomes were measured using the fluorescent probe fluo-4 am. it was noted that synaptosomal ca2+ transport remained virtually unchanged under the influence of plantago polyphenols in zn2+ and mg2+ in rat brain synaptosomal suspensions incubated with lglutamate-fluo-4 am. the polyphenol plantagin competes with glycine for binding to the glycine site of nmda receptors, reducing the likelihood of full receptor activation even in the presence of glutamate, which leads to a limitation of ca²⁺ influx, and therefore plays an important role in preventing excitotoxicity. keywords: plantagin polyphenol, nmda receptor, mg2+, zn2+, synaptosome. introduction: nmda receptors are present in all parts of the central nervous system, located mainly in the postsynaptic and partly in the presynaptic membrane [1]. nmda receptors have also been found to function in astrocytes in the cerebral cortex [2]. the structure of the nmda receptor consists of a complex of 4 separate basic subunits that form an ion channel in the central part that is permeable to ca2+ ions. nmda receptor subunits differ in their physiological and pharmacological properties, and seven subunits have been identified within the complex, including nr1, nr2a–d, nr3a, and nr3b. the nr1 subunit, which binds to glycine, has 8 isomeric forms in the nmda receptor structure, and the nr2a– d subunit, which binds to 1 or 2 glutamic acid and provides the receptor with the function of an ion channel, are the functionally basic structures [3,4]. it is suggested that the nr3a and nr3b subunits expand the spectrum of functional properties of the nmda receptor [5,6]. in clinical and experimental neurology, divalent cations such as mg2+ and zn2+ are widely used as nmda receptor modulators [6,7]. mg2+ ions, which are usually considered endogenous modulators, have been found to be more likely to bind to a specific site of the nmda receptor at a highly negative membrane potential. zn2+ ions bind to the glun2a/glun2b subunits [7]. it is known that magnesium ions play an important role in regulating the activity of nmda receptors. they are potential-dependent receptor blockers, preventing excessive calcium influx and reducing excitotoxicity. adequate amounts of mg2+ are necessary for normal nmda receptor function and synaptic plasticity. zinc (zn2+) ions can also modulate the activity of nmda receptors. they act as positive allosteric modulators, enhancing the response of glutamate receptors. however, excessive levels of zn2+ can lead to neurotoxicity and dysfunction of nmda receptors. nmda receptors are heteromeric tetrameric proteins

(issn: 2771-2745) composed of glun1 and glun2 subunits, which contain d-serine/glycine and glutamate binding sites, respectively. in addition to d-serine/glycine and glutamate binding sites, they have several regulatory sites sensitive to polyamines, zn2+, protons and glutathione [2,7,8,9]. it has been found that mg2+ and zn2+ ions have an inhibitory effect on nmda receptors. these ions can block the nmda receptor channel and reduce its activation by the neurotransmitter glutamate. studies show that the inhibitory effects of mg2+ and zn2+ on nmda receptors are not the same. it has been found that the blocking of the channel by zn2+ is faster than by mg2+. in addition, the effect of mg2+ and zn2+ ions on nmda receptors may depend on changes in ph. therapeutic approaches identified through studies of the effects of mg2+ and zn2+ on nmda receptors suggest that by regulating mg2+ and zn2+ levels, nmda receptor activity can be modulated and neurological diseases associated with nmda receptor dysfunction, such as alzheimer's disease and epilepsy, can be prevented and treated. the aim of the study was to determine the effect of the polyphenol plantagin on nmda receptor sites using glycine, mg2+ and zn2+ ions. methods method for isolating rat brain synaptosome in the studies, rat brain synaptosome suspensions were isolated by differential centrifugation using the method developed and modified by c.w. cotman [10] [11]. the rat was sacrificed by dislocation, the cranial cavity was opened surgically, and the brain was removed. the brain preparation was homogenized in an incubation medium (ph=7.4) containing sucrose (0.32 m), tris-hcl (0.01 m) and edta (0.5 mm) in a ratio of 1:10 under ice water conditions. in experiments, rat brain synaptosomes were isolated using 2/4-step centrifugation [12]. the first centrifugation was carried out at a speed of 4500 rpm and a duration of 10 minutes, and the obtained supernatant was centrifuged at a second stage at a speed of 14000 rpm and a duration of 20 minutes. in the experiments, a kcl solution (35 mm) was used as a plasma membrane depolarizing agent. it is known that under incubation conditions with kcl (35 mm), membrane depolarization occurs and, in turn, activation of ca2+ channels is observed [11]. in the synaptosome, the process of neurotransmitter secretion from the vesicle occurs due to an increase in the concentration of [ca2+]in due to the entry or exit of ca2+ ions from the sr through ca2+ channels located in the presynaptic membrane [13]. method for studying changes [ca2+]in concentration in rat brain synaptosomes. the change [ca2+]in concentration in the suspension medium of rat brain synaptosomes was calculated using the method developed by grynkiewicz et al. [14]. to determine the intracellular calcium concentration (1×108 cl/ml) in synaptosomes, the highly sensitive fluorescent probe fluo-4 am was used. in our experiments, 1 mg of fluo-4 am powdered fluorescent probe was dissolved in 135 μl of dmso to obtain 1 mm fluo-4 am reagent solution. before the experiment, the fluo-4 am solution in dmso was kept at room temperature [15] and 80 μl synaptosomes and 12 μl fluo-4 am were added to 2 ml krebs-ringer buffer and incubated for 30 min at 37°c. fluo-4 am is a fluorescent ca2+ chelator with high affinity for calcium. fluo-4 am can specifically detect intracellular calcium ions with high sensitivity, low cytotoxicity and high content of acetyl methyl ester am, which has good intracellular penetrating ability. after cleavage by intracellular esterase, it remains in the cell, binding to calcium ions and causing strong fluorescence. in the experiments, the fluorescence intensity was recorded using a usb 2000 spectrofluorimeter (ocean optics, usa, 2010). statistical processing of the results was carried out using the specialized software package originpro 7.5 (originlab corporation, usa). the results were obtained in n-fold repetition. also, the statistical reliability of the values between the experimental results and the control group was calculated based on student's t-test and was assessed as statistically significant at values of p<0.05, p<0.01. results obtained and their analysis in our experiments, the effect of plantagin polyphenol on the nmda receptor was studied using zn2+ (5 μm), mg2+ (5 μm) ions and glycine (50 μm). it was found that ca2+ transport in synaptosomes remained virtually unchanged under the influence of plantagin polyphenol under conditions of incubation of lglutamate-fluo-4 am in a suspension of rat brain synaptosomes with zn2+ and mg2+ (5 μm). however, it was found that the activating effect of glycine was relatively suppressed in the presence of glycine (50 μm) (figure 1). the results of this experiment allow us to conclude that the polyphenol plantagin used has both a stimulating and competitive/blocking effect on antagonists and agonists that directly affect the functional activity of the ionotropic nmda receptor. in experiments, glycine binds to the active site of the nmda receptor, activating the calcium channel american journal of applied science and technology 13 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) through the receptor. in subsequent experiments, studies were conducted to determine the complex effect of 50 μm glycine incubated with fluo-4am in the presence of 50 μm concentration of the polyphenol plantagin (figure 1). it turns out that glycine binds to the glycine-binding site of nmda receptors, promoting activation of the ca2+ channel. the obtained results show that the polyphenol plantagin inhibits the increase in calcium dynamics caused by glycine. figure 1. effect of polyphenol plantagin (50 μm) on fluorescence intensity in synaptosomal suspensions of rat brain incubated with glycine (50 μm), zn2+ (5 μm) and mg2+ (5 μm). confidence level. *p<0.05; **p<0.01. this suggests that the polyphenol plantagin may also affect glycine binding sites, suggesting that this polyphenol may be effective in receptor modulation. in terms of discussion of the results, the polyphenol plantagin competes with glycine for binding to the glycine site of nmda receptors, reducing the likelihood of full receptor activation even in the presence of glutamate. this partial inhibition results in a limitation of ca2+ influx and is therefore important for preventing excitotoxicity. competition with glycine reduces nmda receptor activation and the subsequent increase in calcium influx. normally, activation of nmda receptors opens an ion channel, allowing ca2+ to enter the postsynaptic neuron. in neurodegenerative diseases, disruption of this process leads to excessive calcium influx, which can trigger a cascade of harmful processes, including mitochondrial dysfunction, generation of reactive oxygen species (ros), and activation of enzymes that destroy calcium-dependent cellular structures. the polyphenol plantagin inhibits the entry of ca2+ into the postsynaptic neuron by blocking the glycine site and partially inhibiting the activation of the nmda receptor. this process reduces intracellular calcium concentration and stabilizes calcium homeostasis, preventing the harmful effects of excess calcium. plantagin polyphenols reduce the harmful effects of receptor hyperactivation by competitively blocking postsynaptic nmda receptors at the glycine site. this blockade limits calcium influx, reduces excitotoxicity and protects neurons from damage and death. nmda receptors are a subtype of glutamate receptors involved in synaptic plasticity and learning. nmda receptor antagonists prevent calcium ions from entering the cell by blocking the nmda receptor channel. this process helps regulate glutamatemediated excitatory signaling and prevents excessive calcium influx that can lead to neuronal damage. examples of nmda receptor antagonists include ketamine, memantine, and dextromethorphan. memantine binds to nmda receptors more efficiently than mg+ ions. it counteracts the long-term influx of 1 0 20 40 60 80 100 120 * * * * * ** f lu o r e s c e n c e i n te n s it y ( % ) (f 3 4 0 /f 4 9 0 ) control plantagin (50 mkm) glycine (50 mkm) zn 2+ (5 mkm) mg 2+ (5 mkm) plantagin (50 mkm) + glycine (50 mkm) plantagin (50 mkm) + zn 2+ (5 mkm) plantagin (50 mkm) + mg 2+ (5 mkm) american journal of applied science and technology 14 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) ca2+ ions through the nmda calcium channel (which counteracts the voltage-dependent blockade of nmda receptors by mg+ ions due to excess glutamate levels) by temporarily maintaining the physiological activity of the channel due to the high concentration of glutamate released from the synaptic terminal. control of intracellular ca2+ concentration is critical for neurons because it determines their survival and physiological function. because memantine is voltage dependent, it dissociates the average physiological signal from its context and mediates average signal transmission. based on the above data, in our experiments the polyphenol plantagin was compared with the drug memantine, a non-competitive nmda receptor blocker. the effect of the polyphenol plantagin used in these studies on the activity of synaptosomal ca2+ channel suspensions in the presence of memantine was investigated (figure 2). in our experiments, we found that psyllium polyphenols (50 μm) at memantine concentrations (50 μm) had little effect on the calcium content of synaptosome suspension compared to memantine, indicating that this polyphenol does not affect the memantine binding site. figure 2. effect of polyphenol plantagin and memantine (50 μm) on the fluorescence intensity of fluo4-am in synaptosomal suspensions of rat brain. level of significance. *p<0.05;

(n=6). the results of the study indicate that the polyphenol plantagin used does not affect the mg2+ binding sites of the nmda receptor. conclusions it was found that synaptosomal ca2+ transport was virtually unchanged in the presence of plantago polyphenols under zn2+ and mg2+ incubation conditions of l-glutamate-fluo-4 am in rat brain synaptosomal suspensions. the polyphenol plantagin competes with glycine for binding to the glycine site of nmda receptors, reducing the likelihood of full activation of the receptor even in the presence of glutamate. this partial inhibition results in a limitation of ca2+ influx and is therefore important for preventing excitotoxicity. the results of this experiment allow us to conclude that the polyphenol plantagin used has both a stimulating and competitive/blocking effect on antagonists and agonists that directly affect the functional activity of the ionotropic nmda receptor. references hirasawa m, pittman qj. nifedipine facilitates

rapid growth of the body’s psychophysical development, and is characterized by the active formation of a child's personality. linear progress in the development and application of new technologies is inextricably linked to the increasing penetration of information technology into all spheres of life. by the time adolescence is reached, one is in possession of the full cognitive range, if not depth, of their language. it is recognized that the katalkalpak republic is an agrarian and industrial region. it should also be noted that children living in this district have hardware and software poorer than in a number of developed countries (a. deev et al., 2017). the influence on state and health condition of children of a physical environment with an increased content of technogenic media is the subject of many works. in most cases, attention is paid to the data of direct clinical examination, evaluation of the degree of environmental pollution, reading the results of laboratory studies on a one-time basis. blood parameters are often used to describe the state of health and well-being. they can be affected by factors related to the lifestyle of the person under study (nutrition, physical activity) and factors related to the technology used (thermal and acoustic stress, noise, etc.). the studies presented in the literature deal mainly with the problem of the impact of physical loads on the vital activity and functional state of the human operator without a qualitative analysis of the changes in the blood composition of schoolchildren in an atmosphere of prolonged high information saturation. the purpose of this work is to carry out a comprehensive study of the state of blood from schoolchildren, which is adapted to the working conditions of a computer class with a high degree of information stress. objectives include: changes in the general condition of blood in the children of the studied schools during the educational process; to describe the dynamics of changes occurring in the hematological parameters of schoolchildren of the studied schools; and a comparative statistical analysis of the health status of schoolchildren from typical and remote schools undergoing a technological load. https://doi.org/10.37547/ajbspi/volume05issue01-05 https://doi.org/10.37547/ajbspi/volume05issue01-05 american journal of applied science

school age under conditions of environmental impacts is growing significantly in the modern world. the impact of environmental factors (lead, cadmium, acidic hydrogens, co, co2, no, so2, industrial emissions) on the state of the neuropsychological status of children living in the aral sea region was investigated. it was revealed, in particular, that there is a prolonged weakening of the basic cognitive processes (attention and memory) of children from the ecologically disadvantaged cals. the effect of the antigenic structure of food consumed by children living in the aral region on the prevalence of atopic dermatitis and bronchial asthma in them was noted. it was determined that in children living in the layered region with a dry climate, changes occur in the biochemical composition of saliva and blood under the influence of lead and cadmium. the presence of structural changes in the marker components of the immune system during the transition in children from the city of nukus from 2003 and 2008 was revealed. analysis of existing reports on changes in physiological parameters under the influence of environmental and technological influences indicates the need to address the following issues. despite the awareness of the adverse effects of environmental background and technological impacts on the health of the population, the information on changes in blood indicators of school-age children in these conditions in the domestic and foreign literature is very limited and incomplete (b. pankova et al., 2021). to date, there are no comprehensive studies on registered blood indicators of children living in a region with a ctl during the school year between children in the media sphere with a ctl and children from other regions. in karakalpakstan, as well as in other regions of the republic of uzbekistan, the healthcare institutions are not equipped with appropriate devices and equipment for systematic forensic analysis, the use of which is limited by the lack of financial resources and qualified personnel. methodology the purpose of this study is to investigate the characteristics of changes in blood indicators and school-aged children in conditions of technological load to establish an objective information base for the development of medical and preventive measures to minimize the causative context of the emergence of the analyzed states. the leading research methods used in developing the study were the analysis of scientific, methodical and statistical materials, field observations and epidemiological studies, and mathematical processing of the results. in mass screening by the scheduled format, 4544 school-aged children were examined using clinical blood tests. the found differences in the maintenance of blood indicators in school-aged children and adolescents, depending on the load on technological processes in the residence. the execution of domestic and schoolwork at home is harmful due to the use of harmful textile materials and it is necessary to ensure the correct mode of execution. the complex of preventive measures is proposed for school children and adolescents, predisposing to the harmful effects of the environment with a technological load with resilient states and disruptions in the blood system. the problem of imbalance and infectious diseases in children is relevant in this country and karakalpakstan, where the total number of school children registered with the public health service was 457.7 in 2018. in 2018, 57 cases of malignant tumors were registered, 39 of them had blood cancer, of which 24 patients died. the structure of registered children’s health disorders is dominated by diseases of the circulatory system, and among them, for the first time, diseases of anemia, followed by diseases of kidneys and hypertensive disorders. the digital society is developing rapidly. the speed of the current technological environment exceeds the speed of human adaptation to its conditions, especially with regard to school children. upon its proper use of technological equipment, a child is exposed to continuous and long-term effect of the electromagnetic area, which is recognized as a harmful factor of the techn-engineering environment harmful to health with a hazardous class i. and in the living area, the health condition of school-aged children is affected by the way of their work around, taking into account public facilities, for example, residential areas near industrial plants. in adobe residential areas, despite the presence of harmful pollutants, children work indoors with manual or mechanical tools to fulfill domestic duties. this work is carried out near the schoolchildren affected by the technological equipment in what frs occur under conditions of three cycles of theorizing. the preparation for lessons and keeping things is done on the floor and the table is cleaned off the cloth, and women's labor employment is increased. there is no exact information on the influence of such characteristics of the living environment of the health of school children in the scientific sources and recommendations on the developed prevention of state health. study design the study design section explores the study’s framework and the methodology it employed to assess the changes in blood indicators among school-aged children in a specific region where different technological loads are present. this background american journal of applied science and technology 20 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) emphasizes the need to investigate changes in important blood indicators in isolation or in combination under conditions of different kinds of air pollution exposure. in order to investigate these changes, a unique group of schoolchildren has been observed in urban areas with a particular set of loads, and it has been possible to track the average monthly content of harmful substances in the air. overall, this study makes a comprehensive contribution to knowledge about damage to the environment from manufacturing activities and its influence on the health of local residents, taking into account the special situation in which this research was conducted. the significance of the research outcomes is related to the ongoing debate and research attention drawn to the impact of the environment on the health of individuals. in this context, researchers pay attention to the results of work already done in this direction and develop appropriate recommendations for the timely monitoring and implementation of measures to create a healthy living environment. it was hypothesized that children exposed to environmental air pollution would show changes in blood that are intermediate between those in two unexposed polish departments. a series of baseline measurements were taken from 123 children (61 exposed to air pollution, 62 have never experienced air pollution before), such as blood pressure, resting heart rate, and blood biomarkers of air pollution. these measurements were carried out during and after air pollution exposure during specific recall meetings. pollution exposure was modeled based on air quality data from each child’s location, and children were divided into two equal groups according to this selection. random sampling was used. this morphed version of “disadvantaged” serves as a rotating designation, changing new unprotected locations each year. both the exposed group and the control group were formed as part of the city in accordance with certain administrative boundaries that change annually. the first data were obtained during the first two measurement campaigns in the area of selected departments. participants are children and adolescents aged 13-16. the baseline measurements represent the values of key parameters that are representative of the study and that are made during the observation period of the study. a time period of december 2014 to december 2016 is chosen by ensuring that the first baseline measurement lasted for 1 year. participant selection a random sample of 186 children 7-14 years old from the republic of karakalpakstan is examined. for children undergoing monitoring of basic blood indicators in different conditions of technology load of environmental objects and control (out of these conditions) a decrease in the percentage of children with hemoglobin, erythrocytes, erythrocyte content of hemoglobin, alkaline reserve of blood reduced to different degrees. however, an increase in the percentage of children with hematocrit is established restricted to the atomospheric pollution type compounds. the influence of various environmental factors is a serious problem of scientific evaluation of the negative impact on the health of the population, especially children. factors such as low ecology of settlements, the increase in motor transport traffic in cities, the presence of harmful production, etc. contribute to the deteration of the health of children (berra et al., 2007). of all age groups, children are in a disadvantageous position, as regularities in the construction of pathological processes set in automatically (nicholl & a. o’sullivan, 2018). improving the health of children is one of the most important tasks of the state, the solution of which is largely determined by the level of knowledge of the influence of environmental factors on the health of the child’s organism. data collection data collection. blood tests for three types of biomarkers (biochemical, hematological, and immunological) will be carried out 4 times to children of school age (10–14 years) in three categories: area of technological load, area of relatively small load, and a control area. 3.3.1 blood biomarkers and laboratory techniques. biochemical biomarkers include: uric acid, glucose, creatinine, cholesterol (total cholesterol, high density cholesterol, low density cholesterol), triglycerides, total protein, albumin, globulins, bilirubin, urea, alanine transaminase, aspartate transaminase. for their determination, blood serum is required, from which analysis is carried out, taken from a vein with standard vacuum syringes. hematological biomarkers include: red blood cell count, hemoglobin level, hematocrit level, erythrocyte sedimentation rate, color index, white blood cell count, platelet count, granulocyte percentage (relative number of neutrophils and eosinophils), lymphocyte percentage, monocyte percentage. for their determination, blood (in test tubes with an anticoagulant – 3.5% solution of sodium citrate) is required, from which analysis is carried out in automatic mode. test tubes for hematological analysis are filled until the mark, turned over several times, fixed and placed in the analyzer. immunological biomarkers include: ige class antibodies to pollen, house dust, and animal hair, igg class antibodies to viruses causing acute respiratory viral infections: adenovirus, rhinoviruses, respiratory syncytial virus, parainfluenza viruses (1, 2, 3 types). american journal of applied science and technology 21 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) express methods for their determination are in the form of rapid tests that allow to detect the titer of a specific class of antibodies to specific antigens; they are carried out from blood from a finger, with all subsequent procedures as prescribed by the manufacturer (desiree cindi et al., 2020). the study will be carried out in march, june, september, december. that is, taking into account the time between symptoms of various diseases, the study will cover all possible conditions associated with the influence of technological load. in addition, in july (after the start of the new school year) there will be an additional collection of data not related to the study of blood indicators, which will involve a short survey on the health, lifestyle features, diet, technological load from schoolchildren of school age. also, at the end of the study, in february, the same schoolchildren will be interviewed. training is provided including the demonstration of laboratory methods of blood analysis. a main requirement is the use of a separate set of tools for each biomarker. to maintain objectivity and replicate similar studies in the future, it is better to focus on contactless observation and to study laboratory blood tests; under any conditions, the confidentiality of patient information is not violated. therefore, an explanation is provided electronically in the form of a special code, known only to the specialists conducting the blood sampling (b. egan et al., 2022). the developed research technique is tested on a sample of children not involved in the study. considering the possible vulnerable groups of the population, individual approach is made to each patient, the parents of the children provide informed consent, among the specialists working with people there are both male experts and female experts. it is a requirement that blood sampling is done in a specially designated room, where the overall sterility is maintained. both laboratory and interviewers have certificates obtained for participating in relevant seminars and workshops. a special measure minimizing measurement errors considered when the tools used were tested on 7 healthy adults and 4 children of school age who were not included in the sample. results indicator assessment of peripheral blood condition has established statistically significant increase in the hemoglobin content in boys aged 7-9 years under the conditions of technological loading; and, respectively, the concentration of the red pigment substantially raises in boys aged 13-15 years by 14.5% compared to the peers among groups. other blood composition indicators, including the fact of the total content of protein, dextran and cfr, thymol sample spent on the sample, significant enthalpy—in the group of girls aged 10-14 years increases. resistant membranes of blood monocytes are reduced by 19.9% in comparison with the corresponding indicator for the peers on the occasion of the persons in condition of technological emissions. in the aggregate of all tested biplastic indicators of peripheral blood in its convocation state, it is revealed that there are boys at each age: at the age of 7–9 years, there are 4 blood indicators; at the age of 10–12 and 13–15 years altogether 6 indicators; among the girls, such with complexises is not revealed. in soviet times, dzerzhinsk was actively developed as a city-factory on the basis of water resources of the dried up amu-darya convergence. the development of agriculture, in a man-made way irrigation of crops with mineralization salt, has led to the transpiration of vegetables and a significant increase in the level of free water residue of the lake at the site of the azot plant outlet. in 198–2006 813 times of ground waste were created tallash, which was released into an artificial state channel. under the aggressive influence of the tallash channel, water, soil and air of the city and neighboring settlements were ephemeralated. discussion having analyzed the impact of various environmental factors on the body of schoolchildren using the statistical method of ecological regression, experts have established a relationship between the content of pollutants in the air, water and the body of a child. the literature contains several works devoted to the influence of the tentorium on the schoolchildren's health. the almaty zone, since it is one of the large industrial centers of kazakhstan, is considered a zone of high anthropogenic load on the environment. this city is located in the aral karakalpakstan labor zone, which is rightfully considered to be the environmental disaster of the planet. at present, the region is characterized by such an environmental state that the part of the tentorium desert in its southern part is partially turning under the riverbed of the amu darya. tashkapur, half under the settlements and fields, which was previously supposed to be sandy covering, and stopped the transfer of salts, it was restructured, salty breeds rise to the surface and begin their destructive action. as a result, most of the crops, including fodder crops, are dying. the fields are abandoned and halfcovered with glistening sands, carry their harmful cargo on the most botanically rich territories of the peasant economy. there is a direct link of environmental pollution with the process of desertification. major disasters of the region were a result of the ecological situation in the region, a serious technological load on the body of an adult population. the minimum permissible levels of the norms of the maximum allowable concentration of harmful and dangerous american journal of applied science and technology 22 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) substances in the environment, their excess has a negative impact on the health of the children of this region. conclusion the study of blood indicators in school-aged children under conditions of technological loads is important for the timely detection of early age-related changes in the body and is of particular interest in comparison to other indicators (chen et al., 2024). the rare and specific changes that occur in the body of schoolchildren as a result of the impact of man-made pollutants on the technology load, together with new climatic conditions and the hydrosphere of the region, have not been adequately studied. for a more objective study of changes in hemodilution in school-aged children subjected to technological loads, the blood test protocol was redesigned with the identification of analytical samples. for whole blood analysis, the following changes were identified: hematocrit, erythrocyte sedimentation rate, leukocytes, hemoglobin, thrombocytes, platelet-to-leukocyte index, mean platelet volume, platelet distribution width, red blood cells, cell status, cellular and plasma volume, standard score, immaturity, hemoglobin content, average hemoglobin concentration in erythrocytes, average mass of hemoglobin in erythrocytes, percentage of hypochromic erythrocytes, optimal volume of cells, histogram width erythrocytes, antioxidant status, lipid, lipo-lipoprotein, lipidperoxidation, carbonyl, lipid metabolism, and glycated hemoglobin. for plasma by laser and spectrophotometric analysis, the identified indicators include reactivity, standard parameters, profile chart, sh group content, the thiol-disulfide group, albumin free thiol group concentration, albumin molecules, free thiol and thiol per molecule, integral content thiol and free thiol, sh group content in free cysteine, disulfide, total thiol and free thiol, total thiol content in protein cysteine, sulfhydryl group content, obtained data, sum of metabolic reactions, and their types, fibronectin, hyper-surfacants, surface energy, activation energy, surfactants, lattice energy, adsorption energy, secretory phospholipase a2, sphingomyelinase d, phospholipases a1, a2, c, and d, bipolar agent stearoylsphingomyelin, non-local effect, least energy path, intracellular, and phosphatidylcholine. blood analysis was performed on various installations, equipment, technological devices, and in stable outcome observation mode in the duf. blood analysis was performed on sac in laboratory conditions. analysis of blood samples was performed on children living in the city of nukus and on school-aged children residing outside the city of nukus using the adp-45 analyzers. according to the results of the survey, changes in the blood of school-age children who do not have a technological load in the experiment were determined. at the final stage, a comparative analysis of changes in the blood of school-aged children under conditions of exposure to technological loads with those who do not have a technological load was made on 6 parameters of hematocrit, erythrocyte sedimentation rate, leukocytes, platelet-to-leukocyte ratio, hematocrit to leukocytes, and plasma reactivity. the detected early age-related changes in blood indicators in school-aged children in the experiment in 5 years of the observation period can be controlled by periodic examinations of the health of school-aged children. references a. deev, i., l. kolomeets, i., m. kamaltynowa, e., s. kulikov, e., n. levko, a., v. kulikova, k., i. jurkova, v., а. деев, и., л. коломеец, и., м.

helminthology: current trends and challenges ubbiniyazova jamila komekbaevna phd, associate professor, the department of zoology, human morphophysiology and methods of their teaching, nukus state pedagogical institute, uzbekistan received: 16 may 2025; accepted: 12 june 2025; published: 14 july 2025 abstract: the article examines that parasitology and helminthology are rapidly evolving fields that play a critical role in understanding host-parasite interactions, disease pathogenesis, and the development of diagnostic and therapeutic strategies. this article reviews recent advances in the study of parasitic and helminthic organisms, with a focus on molecular diagnostics, host immune responses, epidemiological trends, and emerging patterns of drug resistance. particular attention is given to zoonotic helminths and the implications of climate change and globalization on their distribution and transmission dynamics. furthermore, the integration of omics technologies, such as genomics and proteomics, has significantly enhanced our ability to study parasitic systems at a mechanistic level. this synthesis of current knowledge provides insights into unresolved challenges and highlights potential directions for future research and public health interventions. keywords: parasitology and helminthology, host-parasite interactions, disease pathogenesis, diagnostic, therapeutic strategies. introduction: helminthic and other parasitic infections remain a significant global health burden, particularly in lowand middle-income countries, where they contribute to malnutrition, impaired cognitive development, and increased susceptibility to coinfections. despite the availability of antiparasitic treatments, emerging anthelmintic resistance, environmental changes, and human migration are contributing to the resurgence and geographical spread of many parasitic diseases. there is a pressing need for novel diagnostic tools, targeted therapeutics, and sustainable control programs. advancing research in parasitology and helminthology is therefore essential not only for understanding complex biological systems but also for developing effective interventions to combat parasitic diseases and reduce their socioeconomic impact. in the context of climate change and the pressing need for sustainable development, the effective management of livestock diseases—particularly helminthiases—is of critical importance for enhancing animal productivity and meeting the rising global demand for high-quality protein. this imperative is further underscored by the ongoing depletion of natural resources essential for livestock production and the urgent requirement to mitigate greenhouse gas emissions associated with animal agriculture [1]. addressing these challenges necessitates not only the intensification of production systems but also the adoption of ecologically sustainable and resourceefficient practices, while concurrently ensuring animal welfare. a key component in achieving these objectives is the rigorous control of helminth infections, given their widespread prevalence and substantial detrimental effects on growth performance, feed conversion efficiency, and overall productivity in livestock. historically and contemporarily, helminth control strategies have relied predominantly on the prophylactic and therapeutic use of anthelmintic compounds. however, due to their high genetic plasticity, helminth populations have progressively evolved mechanisms of resistance, leading to the widespread emergence and increasing incidence of anthelmintic resistance (ar), thereby compromising the long-term efficacy of current pharmacological https://doi.org/10.37547/ajbspi/volume05issue07-02 https://doi.org/10.37547/ajbspi/volume05issue07-02 https://doi.org/10.37547/ajbspi/volume05issue07-02 https://doi.org/10.37547/ajbspi/volume05issue07-02 american journal of applied science and technology 7 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) interventions [1]. literature review recent research has highlighted the promising role of plant-derived bioactive compounds in the management of helminth infections. phytochemicals such as cysteine proteases, flavonoids, and condensed tannins have demonstrated anthelmintic efficacy in both small ruminants and bovine species. over the past two decades, approximately 850 peer-reviewed studies have explored the utility of these natural substances against helminths. in vitro studies indicate that condensed tannins and flavonoids—particularly quercetin and luteolin—act synergistically to inhibit the exsheathment of haemonchus contortus third-stage (l3) larvae [1]. these findings suggest that combining plant materials rich in such bioactive compounds, or selectively cultivating forage species with elevated concentrations of these metabolites, may enhance anthelmintic outcomes. crude plant mixtures may target helminthic pathways distinct from those affected by conventional synthetic anthelmintics, potentially offering therapeutic alternatives effective against resistant nematode populations. incorporating bioactive forages into ruminant diets confers dual advantages: nutritional support and antiparasitic action, owing to the presence of plant secondary metabolites (psms) with pharmacological activity. this aligns with the nutraceutical paradigm, wherein dietary constituents contribute to both disease prevention and therapeutic management. globally, efforts are underway to develop nutraceutical-based helminth control strategies tailored to diverse livestock systems. despite these advances, the majority of plant-derived compounds remain underexplored. their anthelmintic efficacy, mechanisms of action, and bioactive constituents require further elucidation. to date, no plant-based anthelmintic has achieved commercial authorization. barriers to widespread adoption include complex regulatory pathways, limited mechanistic insights, potential toxicity, challenges related to residues and standardization, and difficulties in formulation and distribution. the role of nutrition in host-parasite dynamics. nutrition plays a critical role in modulating hostparasite interactions, influencing both the severity of helminth infections and the efficacy of control strategies. gastrointestinal nematodes, for example, compromise host health by impairing appetite, disrupting gastrointestinal function, and altering nutrient metabolism. adequate nutrition, particularly with respect to protein and energy intake, enhances host resilience and supports recovery by stimulating immune function and improving physiological status. micronutrients—including copper, selenium, and phosphorus—also contribute significantly to host immune competence and parasite resistance. such nutritional interventions not only improve animal health but serve as environmentally sustainable complements or alternatives to chemotherapeutic approaches. the integration of targeted nutritional strategies within helminth control programs has the potential to reduce reliance on anthelmintics, particularly within organic and low-input production systems, thereby promoting long-term livestock productivity and welfare. future perspectives on anthelmintic use. although anthelmintics will remain essential in parasite control, their future application is expected to transition from routine prophylaxis to strategic therapeutic interventions. the development of precise diagnostic tools will enable targeted treatment of only those animals demonstrating clinically significant parasitism, marking a paradigm shift toward precision parasitology. this transition may reduce the volume of anthelmintics administered and consequently affect market dynamics, potentially diminishing the commercial incentive for drug innovation. nonetheless, selective treatment with high-efficacy compounds could be economically justified when considering the costs associated with untreated parasitism. moreover, this approach may slow the onset of anthelmintic resistance (ar), thereby extending the lifespan of existing and novel compounds. future anthelmintic products—whether single or multiactive formulations—are likely to be integrated into comprehensive parasite management plans. regulatory frameworks are expected to evolve, enforcing tighter controls on drug use to mitigate environmental contamination and food safety concerns. mandatory diagnostic confirmation prior to treatment may become standard practice. advances in diagnostics, vaccine development, and genetic selection using immunogenetic biomarkers are anticipated to enhance herd-level resilience, reducing dependency on blanket chemoprophylaxis. effective implementation will require knowledge transfer to farmers and veterinarians, alongside economic viability assessments to ensure adoption. toward integrated and sustainable helminth control. traditional helminth control strategies have focused primarily on reducing parasitic loads to improve productivity. however, growing awareness of environmental and welfare implications necessitates a american journal of applied science and technology 8 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) more holistic approach. livestock production systems generate externalities such as greenhouse gas emissions and resource depletion, which are not fully accounted for in market pricing. for example, fasciola hepatica infections in cattle have been linked to a 10% increase in methane emissions per infected animal. effective anthelmintic strategies can mitigate such impacts by improving health and nutrient utilization. while effects on water consumption remain underexplored, they are likely beneficial due to alleviated protein-losing enteropathy. sustainable control measures, such as refugia-based strategies that deliberately withhold treatment from a subset of animals, aim to maintain populations of drug-sensitive parasites. this approach slows the selection pressure for resistance and has become a cornerstone of modern parasite control philosophy. nevertheless, integrated helminth management poses challenges, including increased labor demands, the risk of ar development, and environmental or food safety concerns related to drug residues. future decisionmaking must account for economic, environmental, and welfare trade-offs. emerging evaluation frameworks now consider gastrointestinal nematode management within wholefarm systems, linking health interventions with overall farm inputs, outputs, and sustainability metrics. these tools enable benchmarking and performance comparisons across farms and may inform both private and public policy, even in the absence of direct market signals. regulatory authorities are increasingly recognizing animal welfare and ecological impact as valid criteria in product approval processes. however, the effective application of these holistic methods depends heavily on robust scientific data, which remain limited in many contexts. continued investment in interdisciplinary research—spanning parasitology, animal nutrition, ecology, and economics—is essential to support the development and implementation of optimized, sustainable parasite control strategies across diverse livestock systems. furthermore, in the following we’ll analyze diagnostic innovations: ai enhanced microscopy. recent integration of artificial intelligence and digital microscopy has significantly improved detection of blood and stool parasites. ai models trained on extensive image databases enhance specificity and sensitivity, accelerating smear analysis, though broad implementation remains limited [2] molecular & metagenomic techniques. pcr-based assays, including multiplex panels targeting plasmodium, babesia, filaria, and kinetoplastids, are advancing diagnostics. ngs and metagenomic sequencing enable pathogen detection in complex samples, exemplified by strongyloides stercoralis detection in stool and environmental matrices [3]. crispr based assays. emerging crispr-cas diagnostics, such as sherlock/cas12-based assays, are under feasibility trials and may enable rapid point-of-care testing in the near future [4]. genomic & functional advances. parasite genomics. growing genomic resources for species such as plasmodium, schistosoma mansoni, clonorchis, and opisthorchis are enabling discoveries in virulence, lifecycle regulation, and drug resistance mechanisms [5]. functional genomics & gene editing. tools like rnai and crispr-cas9 are now applicable across helminth taxa. for instance, crispr knockout of schistosoma egg t2 rnase enhances functional studies. similarly, crispr tools in giardia duodenalis aid gene function exploration. epidemiology & zoonotic surveillance. integrative taxonomy. modern integrative approaches combining morphology, histopathology, and molecular markers are being streamlined, though challenges in protocol variability persist [6]. zoonotic dynamics. pcr and sequencing have clarified taxonomy and transmission of zoonotic helminths (echinococcus, trichinella). nevertheless, urbanization, climate change, and wildlife reservoirs complicate control efforts [8]; [20]. regional burden & risk factors. meta-analyses highlight variable infection prevalence in livestock and humans. risk factors—poor hygiene, insufficient sanitation, poverty—remain major drivers in endemic regions [9]. therapeutic & resistance challenges. anthelmintic resistance. mass drug administration (mda), especially with benzimidazoles and ivermectin, risks fostering resistance. there’s an urgent need for field diagnostics to detect early resistance, including qpcr-based allele surveillance. drug delivery innovations. nanoformulations (lipid, polymer, inorganic) for praziquantel improve solubility and bioavailability—vital for managing flatworm infections like schistosomiasis [11]. automation & machine learning. computer vision and machine learning systems (svm, cnns) for parasite egg and protozoan classification have shown ≥90% accuracy in detecting helminth eggs and larvae— offering scalable low-cost diagnostic alternatives [12]. diagnostic sensitivity: standard microscopy (e.g. kato– katz) has limited sensitivity at low prevalence; sophisticated pcr and ngs are costly and not yet fieldamerican journal of applied science and technology 9 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) ready [7]. programmatic constraints: mda coverage gaps, limited funding, and sustainability issues hamper soiltransmitted helminth (sth) control [9]. resource gaps: genomic tools remain constrained in low-resource regions, impeding real-time surveillance and functional studies. resistance surveillance: early detection tools for anthelmintic resistance are lacking, risking treatment efficacy [7]. parasitology and helminthology are undergoing transformative progress. ai-enhanced diagnostics, molecular and genomic tools, and drug delivery innovations are key enablers. yet, field adaptability, infection surveillance, drug resistance monitoring, and resource constraints remain major challenges. addressing these through interdisciplinary research and policy integration will be critical to tackling parasitic disease burden globally. discussion recent years have witnessed transformative advances in parasitology and helminthology, underpinned by innovations in molecular diagnostics, geospatial analytics, vaccine development, and integrated management strategies. molecular tools and taxonomic resolution. highthroughput sequencing (ngs), pcr-based assays, and omics technologies have revolutionized parasite taxonomy and population genetics. genomic studies of plasmodium falciparum, trypanosoma, and various helminths have elucidated drug-resistance mechanisms and host adaptation patterns [10]. integrative taxonomy combining molecular, morphometric, and ecological data has become the gold standard in helminth classification, as recently demonstrated in integrative taxonomy in helminth analysis [1]. diagnostic and surveillance tools. automated imagebased diagnostics, such as hybrid cnn-svm systems for helminth egg detection, are emerging as rapid, costeffective approaches that improve accuracy while reducing labor. molecular lamp assays and immunoassays (e.g., for fascioliasis) have similarly improved field detection capabilities [15]. vaccine and therapeutic development. helminth vaccine research has advanced with candidates like na gst 1 and new adjuvant systems now in phase ii trials. novel small molecules targeting metabolic pathways offer promise in overcoming anthelmintic resistance [16]. continued investment in antigen discovery is needed to translate these candidates into clinical use. impact of climate change and one health approaches. climate-shift–driven expansion of vector and parasite ranges is evident around the globe. integrating gis, earth observation, and climate modeling has improved risk mapping for diseases like fascioliasis and schistosomiasis [18]. one health paradigms are vital to understand zoonotic spillover and integrate animal– human–environment surveillance [20]. computational modeling and data integration. mathematical models quantifying human–animal– environment transmission dynamics for soil transmitted helminths have provided insights into key control parameters and intervention thresholds [14]; [21]. machine learning tools applied to ntd surveillance and diagnostics have demonstrated enhanced predictive power, though challenges remain regarding data quality and algorithm bias. ecological and conservation perspectives. recognition of parasite conservation has emerged as a field unto itself, underscoring the ecological value of parasite biodiversity and its role in ecosystem functioning [22]. ecological parasitology, focusing on community dynamics and host–parasite coevolution, continues to mature with theoretical and empirical contributions. conclusion the field of parasitology is evolving at a rapid pace. molecular diagnostics, geospatial modeling, vaccine research, and one health approaches have significantly advanced our understanding and control of parasitic diseases. however, realizing their full potential requires addressing translational bottlenecks, combating drug resistance, integrating diverse data streams, and ensuring equitable implementation in endemic regions. thus, the challenges and future directions are: translational gaps: while diagnostics and vaccine candidates show promise, advancing from bench to field remains slow. barriers include funding deficits, regulatory complexity, and the intricate biology of many parasites [23]; anthelmintic resistance: resistance to benzimidazoles, ivermectin, praziquantel, and macrocyclic lactones is emerging in both human and livestock helminths. coordinated surveillance and integrated control frameworks are urgently needed [23]; data integration: harmonizing heterogeneous data types—molecular, spatial, phenotypic—remains complex. better data-sharing platforms and cross-sector collaboration are critical; equity and access: surveillance, diagnosis, drug access, and public health infrastructure often remain inadequate in endemic regions. strengthening local capacity and engaging communities is essential for sustainable impact. references agrawal v. et al.

consequences of disruption: role in brain protection and maintenance of homeostasis. disturbances in strokes, neuroinfections , neurodegeneration , tumors petrova yurita yurievna assistant professor, department of biomedical sciences, emu university, uzbekistan received: 17 april 2025; accepted: 24 may 2025; published: 30 june 2025 abstract: the blood-brain barrier (bbb) is a complex morphofunctional system that ensures selective permeability between the bloodstream and tissues of the central nervous system. this article discusses the anatomical and histological structure of the bbb, its key functions in protecting the brain and maintaining neuronal homeostasis. particular attention is paid to the mechanisms of barrier function impairment in various pathological conditions strokes, neuroinfections , neurodegenerative diseases and brain tumors. the consequences of bbb dysfunction and modern approaches to diagnostics and therapy, including pharmacological modulation and targeted drug delivery technologies are analyzed. the presented material emphasizes the importance of maintaining the integrity of the bbb for neuroprotection and treatment of a wide range of neurological disorders. keywords: blood-brain barrier, neurohomeostasis , permeability, stroke, neuroinfections, neurodegenerative diseases, brain tumors, cerebral edema, tight junctions , neuroinflammation. introduction: the human central nervous system (cns) is highly sensitive to changes in the internal and external environment, which necessitates its reliable protection. one of the key structures that ensures the isolation of the brain from potentially harmful substances circulating in the systemic bloodstream is the blood-brain barrier (bbb). this unique structure, formed by tight junctions of endothelial cells of brain capillaries, pericytes, astrocytes and the basement membrane, acts as a selective filter and active regulator of exchange between blood and nervous tissue. the bbb not only prevents the penetration of toxins, pathogens and immune cells into the brain parenchyma, but also participates in maintaining ionic balance, nutrient delivery, and regulating neuroinflammatory reactions. violation of the integrity and function of the bbb underlies the pathogenesis of a wide range of neurological diseases, including ischemic and hemorrhagic stroke, neuroinfections , multiple sclerosis, alzheimer's disease and brain tumors. modern concepts of the structure and functions of the bbb, as well as the mechanisms of its disruption, are important not only for diagnostics, but also for the development of new therapeutic approaches, including methods of targeted drug delivery to the central nervous system. the purpose of this article is to systematize existing data on the morphology and functions of the bbb, analyze the neurological consequences of its disruption, and consider promising areas in the restoration and modulation of the barrier function in various diseases. purpose of the study to study the structure and functions of the blood-brain barrier and analyze the consequences of its disruption in various neurological diseases. materials and methods the study used modern literature data, including experimental and clinical studies devoted to the https://doi.org/10.37547/ajbspi/volume05issue06-06

(issn: 2771-2745) morphology, functions and disorders of the blood-brain barrier (bbb). the analysis was carried out on the basis of publications obtained from the scientific databases pubmed , scopus , web of science over the past 10 years. to illustrate the mechanisms of bbb disruption, the results of morphological and biochemical studies on animal models of stroke, neuroinfections and neurodegenerative diseases, as well as data from clinical observations of patients with similar pathologies are considered. methods included studying the barrier structure using electron microscopy, immunohistochemical analysis of tight junctions ( tight junction proteins ), as well as assessment of functional permeability using contrast imaging techniques and inflammatory biomarkers . results and discussion the analysis of literature and experimental data confirmed the complex and multi-level structure of the blood-brain barrier (bbb), which ensures its high selectivity and protective function. endothelial cells with tight junctions ( claudin , occludin , zo-1) form the main physical barrier, supported by astrocytic endothelial cells and pericytes. violation of the integrity of these components leads to increased permeability of the bbb and the development of neurological complications. strokes are associated with significant weakening of tight junctions and activation of matrix metalloproteinases (mmp-9), which is accompanied by vasogenic edema and increased inflammation. these processes contribute to secondary damage to brain tissue and worsen the prognosis. similarly, in neuroinfections , pathogens and inflammatory mediators destroy the barrier, facilitating access for immune cells, but simultaneously increasing the risk of edema and neuronal damage. in neurodegenerative diseases such as alzheimer's disease and multiple sclerosis, bbb dysfunction is associated with impaired β-amyloid transport, increased neuroinflammation , and lymphocyte infiltration into the cns, which accelerates disease progression. tumor growth, especially in glioblastomas , is accompanied by the secretion of factors that destroy the barrier and cause vasogenic edema, which complicates treatment and worsens the quality of life of patients. modern diagnostic methods, including contrast mri and inflammation biomarkers , allow for timely detection of bbb disruptions. therapeutic strategies aimed at barrier stabilization, mmp inhibition, and targeted drug delivery through temporary bbb opening show promise for improving clinical outcomes. thus, maintaining the integrity of the bbb is critical for neuroprotection and effective treatment of many cns diseases. conclusion the blood-brain barrier is a key element of brain protection, ensuring selective transport of substances and maintaining homeostasis of the central nervous system. disruptions in the integrity and function of the bbb play an important role in the pathogenesis of many neurological diseases, including strokes, neuroinfections, neurodegenerative processes and brain tumors. understanding the mechanisms of barrier disruption opens up new opportunities for diagnostics and the development of effective therapeutic approaches aimed at restoring and modulating its function. further research in this area will contribute to improving the treatment and prevention of neurological disorders. references 1. abbott nj, patabendige aak, dolman dem, yusof sr, begley dj structure and function of the blood– brain barrier. neurobiology of disease . 2010;37(1):13-25. 2.

2025 abstract: basically, the morphometric parameters of the cells and fibrous structures of the kidney in the morphofunctionally actively stained areas were taken as the basis for expressing the trajectory of the values measured during the morphometry process within a certain range by numbers. the specific features of the morphometric parameters of the parenchymal and mesenchymal structures of the kidneys of 40 women who died from gestational pyelonephritis, who underwent autopsy at the republican pathologoanatomical center of uzbekistan, were studied using the hamamatsu (qupath-0.4.0, nanozoomer digital pathology image) morphometric software. to determine the morphometric parameters, the location, size, area occupied, size of cells, width of blood vessels, diameter, perimeter, volume of lumens in a given volume and other indicators were obtained. in the study, the superiority of all morphofunctional parameters over the control group was up to 1.35 times in the i-pregnancy, up to 1.2 times in the ii-pregnancy, which was explained by the weakness of morphological adaptation mechanisms, a decrease in the age-related reactivity of vascular components. keywords: borphometry, kidney, gestational pyelonephritis, pregnancy. introduction: according to the who (2022), pregnant women make up an average of 11.7% of the world's population. during the second and third trimesters of pregnancy, the development of morphofunctional obstructions in the urinary system can occur, leading to compression of the ureters coming from the kidneys. this causes urinary stasis and, with the addition of infectious agents, results in the development of gestational pyelonephritis [1, 2, 6]. the incidence rate of gestational pyelonephritis corresponds to the number of pregnancies and births and is observed in approximately 2–4% of all pregnant women in the united states and european countries, around 2–3% in japan, south korea, and india, and on average 2–10% in cis countries and the russian federation. in the republic of uzbekistan, this indicator averages 10–18%. the development of gestational pyelonephritis during childbirth and the postpartum period accounts for approximately 6–25%, underscoring the urgency of the problem. the mortality rate due to kidney complications arising during pregnancy and the postpartum period is on average 1–3% per 1000 pregnant women [3, 4, 5]. research aim and objectives to study the changes in renal morphometric parameters in gestational pyelonephritis depending on pregnancy parity. https://doi.org/10.37547/ajbspi/volume05issue06-08

anatomy between 2020 and 2023 and involved 40 women who died during pregnancy due to renal pathologies. the specific morphometric characteristics of the renal parenchyma and mesenchymal structures in cases of gestational pyelonephritis were analyzed using the hamamatsu (qupath-0.4.0, nanozoomer digital pathology image) morphometric software. results for morphometric examination, kidney tissue samples were obtained from the autopsies of patients who suddenly died of myocardial infarction (control group, n=17). as the experimental group, kidney tissue samples were taken from autopsies of women of various reproductive ages who died during pregnancy due to acute renal diseases. the prepared kidney tissue materials were scanned using the nanozoomer, and microimages were obtained. morphometric parameters were determined based on cellular localization, volume, occupied area, size, width, diameter, perimeter, lumen volume of blood vessels, and other relevant indicators within a defined volume. specifically, morphometric analysis identified dystrophic changes in the functional active areas of the renal parenchymal components, while inflammatory changes were observed in the mesenchymal parts, such as the glomeruli and tubules, which serve as key indicators of pathological alterations. our study revealed distinctive features of the examined tissue, including the complete integrity of all glomerular blood vessels, a 17–28% increase in glomerular weight compared to the control group, focal detachment in the epithelium of proximal and distal tubules, presence of coarse proteinaceous inclusions in the cytoplasm, massive multifocal desquamation in the epithelium, and nuclei exhibiting karyopyknosis, karyorrhexis, and karyolysis due to necrobiosis. additionally, thickening of the basal membrane of proximal tubules, accumulation of coarse homogeneous proteinaceous substrate in the lumen of distal tubules, massive congestion of peritubular capillaries, diapadesis hemorrhages, and a significant decrease in reabsorption capacity of proximal tubules were observed. morphometrically, the changes associated with gestational pyelonephritis were studied according to the number of pregnancies. table 3.1. morphometric parameters (number and micrometers) of renal injury areas in gestational pyelonephritis studied parameters control group i trimester ii

shape and have undergone compressive deformation. scanned using nanozoomer. staining: h&e. size: 20×10. the average diameter of the renal glomeruli in the control group was 166.8±1.1 µm. in comparison, this parameter increased to 209.3±1.1 µm in the kidneys of the first group of pregnant women with gestational pyelonephritis during the first trimester, showing a 1.25-fold increase. these changes correspond to the morphological signs described above, particularly the vascular response within the glomerular capillary network. the observed increase in filtration, marked vasodilation, and enlargement of the glomeruli confirm that these alterations are most pronounced in gestational pyelonephritis occurring during the first trimester. in the second trimester, this indicator measured 191.1±1.01 µm. from an age-related perspective, this is explained by a reduction in vascular elasticity, and compared to the first-trimester group, vessels became more fragile and thickened. as a result, the extent of vasodilation was less pronounced. nevertheless, this parameter was still 1.15 times higher than that of the control group, confirming its significance. figure 2. graphical representation of the average perimeter of the shumlyansky–bowman’s space of the renal glomerulus. scanned using nanozoomer. staining: h&e. size: 20×10. in the third trimester, the same parameter measured 173.2±1.1 µm. this value can be explained by agerelated changes, such as a marked reduction in vascular elasticity, increased fragility of blood vessels compared to groups i and ii, and a decrease in elastic fibers within the vessel walls. additionally, reduced reabsorption capacity in the renal tubules contributes to this finding. the parameter was 1.03 times higher than that of the control group, confirming its significance. as for the glomerular perimeter, it was 256.7±1.03 µm in the control group, while in the first trimester group, it increased to 343±1.05 µm. this represents a 1.34-fold increase, indicating significant vascular congestion within the glomeruli and intensified filtration processes, which in turn led to the expansion of bowman’s space, thus supporting the observed morphological findings. american journal of applied science and technology 35 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) figure 3. the renal glomerulus with illustrated epimetric and perimetric measurements of the shumlyansky–bowman’s space, showing one-quarter of the segmental diagonal diameter. scanned using nanozoomer. staining: h&e. size: 20×10. in the second group (i.e., during the second trimester of pregnancy), the perimeter of the renal glomeruli was 314.5±1.1 µm, showing a 1.22-fold enlargement. this enlargement is explained by damage to the glomeruli during chemotherapeutic treatment for gestational pyelonephritis and by an increase in filtration parameters. in the third group (i.e., third trimester of pregnancy), the glomerular perimeter measured 293.1±1.21 µm, which is 1.14 times greater than in the control group. this finding indicates a reduced adaptive response in this stage of pregnancy. the next morphometric indicator is the average area occupied by the glomerular tuft (15000 µm²). in the control group, this area was 10365±5.61 µm², whereas in the first trimester, it increased to 12281±3.25 µm², confirming the results observed in the other morphometric measurements. in terms of the proportion of the glomerulus occupied by the capillary tuft, 69.1% of the area was occupied in the control group, compared to 82% in the first group. this indicates pronounced vascular dilation and elevated filtration capacity, as well as ongoing vascular damage occurring in parallel. these findings collectively support the notion that renal insufficiency may develop following any course of chemotherapeutic treatment american journal of applied science and technology 36

diameter of the proximal and distal renal tubules. scanned using nanozoomer. staining: h&e. size: 20×10. in the second group (i.e., second trimester of pregnancy), the area occupied by the glomerular tuft was 10,995±8.3 µm², comprising 73.3% of the total glomerular area (15,000 µm²). compared to the control group, this represents a 4.2% increase, although statistically of low significance. in the third group (third trimester), the tuft area measured 10,725±2.92 µm², accounting for 71.5% of the total, which is very close to the control group and statistically not significant, indicating that vascular reactivity in the glomeruli during this period does not differ substantially from the baseline. the next stage of examination focused on the shumlyansky–bowman’s space, which is critical for evaluating the morphofunctional characteristics of the glomeruli. in the control group, the average width of this space was 18.31±1.01 µm, while in the first trimester group, it decreased to 15.21±1.01 µm, indicating a narrowing of bowman’s space. this is interpreted as a result of the marked enlargement of the capillary tuft and vascular hyperemia, reducing the available space. this reflects a 1.2-fold decrease. in the second trimester, the bowman’s space measured 17.42±0.97 µm, showing a 10.5% reduction compared to the control group, which was considered statistically less significant. in the third trimester, the measurement was 18.21±1.01 µm, with no meaningful difference from the control group. this suggests that the structure and function of the glomerular tuft and bowman’s space remained largely intact. subsequent morphometric analysis involved measurements of renal tubules in various projections, comparing them to the control group. for the proximal tubules, the average diameter in the control group was 121.12±5.01 µm, while in the first trimester, it expanded to 162.11±8.16 µm, showing a 1.2-fold increase. this can be attributed to increased filtration activity, enhanced reabsorption, and the development of dystrophic changes in tubular epithelium, leading to cellular swelling and tubular dilation. in the second trimester, the proximal tubule diameter reached 152.5±7.13 µm, 1.15 times larger than the control group. this reflects ongoing epithelial damage, with histological evidence (at 200× magnification) of dystrophic changes, including hyaline droplet degeneration and hydropic degeneration. notable findings included epithelial detachment, cellular desquamation, and karyolysis-like foci. in the third trimester, the proximal tubule diameter was 135.31±5.21 µm, 1.12 times larger than in the control group, and was considered statistically significant. this enlargement is attributed to various degrees of epithelial swelling. the inner diameter of the proximal tubules in the control group was 43.01±0.01 µm. in the first trimester, this reduced to 36.2±1.01 µm, a 1.2-fold decrease, primarily due to enlargement of epithelial cells. in the second trimester, the diameter was 37.1±1.01 µm, american journal of applied science and technology 37 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) indicating a 1.15-fold reduction, with less pronounced changes with age. in the third trimester, the inner diameter was 39.2±1.01 µm, showing a 1.1-fold decrease compared to the control group, but this difference was not statistically significant. regarding the distal tubule diameter, it measured 61.12±1.4 µm in the control group, while in the first trimester, it reached 84.36±12.50 µm. this increase reflects tubular enlargement and corresponds with the presence of dystrophic and necrobiotic changes in the epithelium. in the second trimester, the distal tubule diameter was 78.14±1.6 µm, 1.3 times larger than in the control group. in older individuals (ages 60–74), this measurement averaged 68.11±1.3 µm, which is 1.11 times larger than controls, although the difference was statistically insignificant. these findings indicate that age-related reductions in adaptive capacity contribute to a lesser degree of change in the distal tubules conclusions multiplex morphometric studies revealed that agerelated renal damage indicators were significantly elevated in all study groups compared to the control group. in the first trimester of pregnancy, morphofunctional parameters were markedly elevated, with more pronounced damage observed. on average, the size of all renal components increased by up to 1.35 times relative to the control group, reflecting vascular dilation and overall morphological dominance of injury features, making this the most affected group. in the second trimester, these parameters were, on average, up to 1.2 times higher than in the control group. this was explained by weaker rapid morphological adaptation mechanisms and a decline in vascular component responsiveness due to age-related changes. in this group, renal damage indicators showed 10–15% variability compared to the control group, confirming moderate but notable pathological differences. references laletin d.i., et al. obstruction of the

april 2025 abstract: enterosorbents are widely used in gastroenterology, toxicology, infectious diseases, allergology, dermatology, surgery, oncology, hepatology, nephrology, and addiction medicine. to expand the range of enterosorbent preparations using natural raw materials, the physicochemical and technological properties of the natural mineral glauconite were studied as a promising source for the developing granulated, encapsulated, and tablet-form oral enterosorbent preparations. keywords: enterosorbent, adsorption, absorption, endotoxins, exotoxins, technology, oral preparations, granules, and capsules. introduction: the development of enterosorbent preparations with adsorption and detoxification pharmacological effects is one of the promising areas in pharmaceutical practice. enterosorbents are medicinal substances of various structures and nature, whose mechanism of action is aimed at binding and eliminating exoand endotoxins from the body through the gastrointestinal tract by adsorption, absorption, ion exchange, and complex formation. depending on the mechanism of action, sorbents can be divided into: 1) adsorbents substances with ion-exchange properties; 2) complexing agents substances that, in a molecular or ionic state, form stable compounds with ligands that, in turn, bind and eliminate from the body toxins of biologically active substances (antigens, histamines, prostaglandins, bilirubin, xenobiotics, etc.), pathogenic bacteria, and their toxins. in the cases mentioned above, the mechanism of sorption is related to both direct and indirect effects. the therapeutic-chemical classification of enterosorbents includes compounds such as activated charcoal, bismuth preparations, pectin, kaolin, croscarmellose, attapulgite, diosmectite, and their combined compositions [1, 2]. currently, enterosorbent preparations are mainly imported into uzbekistan from abroad and do not fully meet the needs of our country. therefore, expanding the range of preparations with sorptive properties is an urgent task for modern pharmaceutical technology. based on the above, this study aims is to analyze the market of enterosorbent pharmaceutical preparations and biologically active additives (baa) registered in the republic of uzbekistan and to determine the potential for expanding the range of medicinal products and baas with enterosorbent properties using local natural https://doi.org/10.37547/ajbspi/volume05issue04-09 https://doi.org/10.37547/ajbspi/volume05issue04-09 https://doi.org/10.37547/ajbspi/volume05issue04-09

(issn: 2771-2745) raw materials with sorptive properties, such as glauconite. the study will examine the physicochemical and adsorption properties, as well as the pharmacological properties of the natural mineral sorbent glauconite, to develop granulated and encapsulated enterosorbent forms in the future. methods the analysis of official sources of information on pharmaceutical preparations and biologically active additives (baa) registered in the republic of uzbekistan [3, 4] was conducted. the object of the study was the natural highly dispersed glauconite powder extracted by open-pit mining from the sandstone of the "changi" quarry (parkent district, tashkent region, republic of uzbekistan) and thermally processed to activate it in the laboratory production conditions of llc "fatiderm." the thermal activation process was carried out in a laboratory drying oven "shsu-m1" (russia) at temperatures ranging from 100 to 300°c, as well as in a laboratory muffle furnace "mp-2um" (vilnius, lithuania) at temperatures ranging from 400 to 800°c. thermogravimetric studies of the sieved fraction of glauconite were conducted using a derivatograph from mom company in the temperature range of 200-800°c with a heating rate of 10k/min. the study of the physicochemical and technological properties of thermally activated glauconite, as well as the quality indicators of trial samples of granules and encapsulating mass of glauconite, was carried out according to the methods described in the literature [5]. results and discussion currently, the state register of medicinal products, medical devices, and equipment permitted for use in medical practice in the republic of uzbekistan includes 1 pharmaceutical substance with sorptive properties and 20 pharmaceutical products and dietary supplements (baa). these medicinal products contain enterosorbents derived from substances of 5 types: activated charcoal (4), colloidal silica (2), polymethylsiloxane polyhydrate (1), dioctahedral smectite (5), hydrolytic lignin (2), and 6 types of baas [3, 4]. the listed enterosorbent products are available in the form of powders (suspensions), granules, tablets, capsules, pastes, and gels [2, 3]. among the registered enterosorbent products in uzbekistan, the most popular are smecta®, polysorb mp, and enterosgel®. for many years, enterosorbents based on wood charcoal, wood, limestone, and silica have been widely used worldwide. however, as experiments have shown, activated charcoal has the lowest sorptive activity—10 mg/g (d.a. markelov, o.v. nitsak, i.i. gerashchenko, 2008). therefore, the demand for these substances is gradually decreasing. as a result, scientists from various countries are actively researching new promising sorptive materials with a wide range of sorptive activity [2, 5]. given the above, a promising sorbent with a broad spectrum of action is the natural mineral glauconite. glauconite (glauconite) is a potassium-containing aluminosilicate with a complex and variable composition (chemical formula (kna)(fe3.al mg)2(sial)4o10(oh)2). glauconite belongs to the group of hydrous micas, a subclass of layered silicates. this relatively inexpensive natural mineral has a wide range of sorptive activity, high ion-exchange and buffering properties (depending on fractionation from 200 to 600 μm, the sorptive properties of glauconite range from 20 to 100 mg/g, and after activation using magnetic separation methods, its activity increases by an additional 45%). a large absorption area was also noted, with the specific sorption surface ranging from 0.10 to 0.16 mmol/g depending on the ph of the medium (ph 5.2-7.5). additionally, the coating (encapsulating) properties of glauconite were studied. the sample of glauconite mineral under study is a polydisperse powder of a dark olive-green colour, odorless and tasteless, and insoluble in water. examination of the glauconite powder under a scanning electron microscope (sem) showed that the particles of glauconite have an isodiametric globular form, in the shape of spheres, ovals, and kidney-like forms. a significant number of particles have an irregular shape with a bumpy, matte surface, and the surfaces of the particles are cracked. the density of the powder ranges from 2.2 to 2.9 g/cm³; the particle size after fractionation was less than 0.2 mm (84.6% = 2.2%). porosity plays a significant role in the sorption process, i.e., the presence of spaces between interconnected pores. porosity is a property of solid bodies characterized by the presence of voids between granular particles, crystals, and layers. particles of different enterosorbents differ from each other in structure and pore radius. the porosity of glauconite was determined according to gost 30629-99, and it was found that the porosity of the glauconite fraction ranging from 200-500 μm is 22±1.8%. glauconites extracted from various regions of uzbekistan have different chemical compositions (table 1). the type of glauconite in which potassium predominates is called celadonite (for example, samples of glauconite extracted from the deposits in the namangan region are rich in potassium ions). american journal of applied science and technology 40 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) table 1 chemical

enterosorbent pharmaceutical preparations, the physicomechanical properties of thermally activated glauconite samples were examined after heating for 30 minutes at 400°c. the results of the studies are presented in table 3. as shown by the results of the study of the physicomechanical properties of the thermally activated glauconite substance: it is a polydisperse powder, the particles of which are isodiametric in shape (spherical grains of various sizes), olive-green in colour, odourless, tasteless, and insoluble in water. during fractionation, it was found that the majority of the particles are less than 200 μm in size (69.84%). this indicates the need for further grinding of the substance and sieving through a sieve with a hole diameter of 150 μm. the following properties of glauconite, such as relative density, bulk density, flowability, angle of repose, degree of compaction, and residual moisture, are within the normal range. however, the compressibility index is unsatisfactory; glauconite powder is classified as an elastic substance, and to obtain quality granules and encapsulating mass, a wet granulation process with the use of binders with high adhesive activity is required. american journal of applied science and technology 41 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) table 3.

result of the analysis of official sources of information on pharmaceutical drugs and dietary supplements, it was established that the range of enterosorbent drugs in the republic of uzbekistan is relatively broad: 1 pharmaceutical substance, 14 american journal of applied science and technology 42 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) pharmaceutical drugs, and 6 named dietary supplements. these drugs are mainly available in the form of powders (42.9%), tablets (42.9%), and capsules (7.1%), as well as one original product in a sachet-paste form, "enterosgel" (7.1%). the composition of the listed dietary supplements is diverse, and they are available in the form of powders, capsules, tablets, and syrup for drinking. since most enterosorbent drugs are imported into the republic of uzbekistan, a promising direction is the study of the physicomechanical properties of glauconite to develop the composition and technology for granulated and encapsulated enterosorbent oral drugs based on it. references анализ энтеросорбентов, представленных в розничном звене фармацевтического рынка/г.а. галкина, е.и.

a prevalent metabolic disorder that affects millions of people worldwide. when it occurs during pregnancy, it poses significant challenges for both the mother and the developing fetus. diabetes mellitus during pregnancy, including both gestational diabetes (gdm) and pregestational diabetes, is associated with various maternal and fetal complications. one of the most concerning complications is hypertension, which can manifest as gestational hypertension or preeclampsia. these hypertensive disorders not only threaten the health and well-being of the mother but also increase the risk of adverse perinatal outcomes, including preterm birth, low birth weight, and increased neonatal morbidity and mortality. the interplay between diabetes mellitus and hypertension during pregnancy is complex and multifactorial. several pathophysiological mechanisms have been proposed to explain this association, including endothelial dysfunction, insulin resistance, and inflammatory processes. pregnant women with diabetes are already at a heightened risk of vascular complications due to the metabolic disturbances caused by hyperglycemia. the additional burden of increased blood pressure further exacerbates these risks, leading to a higher likelihood of developing severe hypertensive disorders. this interplay underscores the importance of understanding the specific factors contributing to hypertension in diabetic pregnancies. despite the well-established link between diabetes and hypertension during pregnancy, there is still a need for comprehensive studies that quantify this risk and identify modifiable risk factors. while some studies have explored the prevalence of hypertension in women with gestational diabetes, less attention has been paid to the entire spectrum of diabetic conditions during pregnancy, including pregestational diabetes. furthermore, existing research often lacks a clear stratification of risk based on different demographic and clinical variables such as age, body mass index (bmi), and family history of hypertension. understanding these nuances is crucial for developing targeted interventions that can mitigate the risk of hypertension and improve outcomes for both mothers and infants. the present study aims to fill this gap by assessing the risk of hypertension in pregnant women with diabetes mellitus. by examining a diverse cohort of pregnant women, we seek to provide a comprehensive overview of the prevalence of hypertensive disorders in this population and identify key factors that may influence this risk. through a detailed analysis of clinical and demographic data, this study will contribute to a better understanding of the complex relationship between diabetes and hypertension during pregnancy. ultimately, our goal is to inform clinical practice by highlighting the need for early detection, continuous monitoring, and personalized management strategies

pregnant women with diabetes. method this study employed a retrospective cohort design to assess the risk of hypertension in pregnant women diagnosed with diabetes mellitus. the research was conducted in a tertiary care hospital, drawing upon medical records from january 2015 to december 2023. the study population consisted of pregnant women aged 18 to 45 years who were diagnosed with either gestational diabetes mellitus (gdm) or pregestational diabetes (type 1 or type 2 diabetes diagnosed before pregnancy). inclusion criteria were strictly set to ensure a homogeneous study group, encompassing only those with a clear diagnosis of diabetes mellitus during pregnancy and a complete antenatal care record. women with chronic hypertension diagnosed before pregnancy, multiple gestations, or other preexisting conditions such as renal disease or autoimmune disorders were excluded to isolate the effects of diabetes mellitus on hypertension risk. data collection involved the systematic extraction of relevant information from the electronic medical records of eligible participants. key variables included demographic data (age, ethnicity, body mass index [bmi] at the first prenatal visit), clinical history (type and duration of diabetes, glycemic control levels indicated by hba1c at the first trimester, and gestational age at diagnosis of gdm), and obstetric history (parity, history of hypertensive disorders in previous pregnancies). additional data points collected were blood pressure readings recorded at each prenatal visit, medication use (insulin or oral hypoglycemic agents), and any episodes of hypertensive disorders, categorized as gestational hypertension or preeclampsia according to the american college of obstetricians and gynecologists (acog) guidelines. the primary outcome of interest was the development of hypertensive disorders during pregnancy, specifically gestational hypertension and preeclampsia. hypertension was defined as a sustained blood pressure reading of ≥140/90 mmhg on two separate occasions at least four hours apart after 20 weeks of gestation in women who were previously normotensive. preeclampsia was defined as gestational hypertension accompanied by proteinuria (≥300 mg per 24-hour urine collection) or, in the absence of proteinuria, any of the following: thrombocytopenia, renal insufficiency, impaired liver function, pulmonary edema, or new-onset cerebral or visual disturbances. to examine the relationship between diabetes and hypertensive disorders, the study utilized multivariate logistic regression models, controlling for potential confounders such as maternal age, bmi, parity, and family history of hypertension. data analysis was conducted using spss software version 26.0. descriptive statistics were employed to summarize demographic and clinical characteristics, presenting means and standard deviations for https://doi.org/10.37547/ajbspi/volume03issue03-01

volume 04 issue 09 pages: 8-14 oclc – 1121105677 publisher: oscar publishing services servi continuous variables and frequencies and percentages for categorical variables. the incidence of hypertensive disorders was calculated for each subgroup of diabetes (gdm, type 1, and type 2) to discern any variations in risk. univariate analyses were initially performed to identify factors associated with hypertension development, with variables achieving a p-value of less than 0.05 included in the multivariate models. the adjusted odds ratios (ors) and 95% confidence intervals (cis) were reported to quantify the strength of association between diabetes mellitus and the risk of hypertensive disorders, while also considering the modifying effects of other covariates. to ensure the robustness of our findings, sensitivity analyses were conducted by stratifying the sample based on key variables such as bmi categories, glycemic control levels, and the use of antihypertensive medications. these analyses aimed to assess the consistency of the observed associations across different subgroups and to identify any potential effect modifiers. additionally, subgroup analyses were performed to compare outcomes between women with gdm and those with pregestational diabetes, given the potential differences in pathophysiology and management approaches between these groups. ethical approval for the study was obtained from the hospital’s institutional review board (irb), ensuring compliance with all ethical standards for research involving human subjects. all data were anonymized to protect patient confidentiality, and the study adhered to the principles of the declaration of helsinki. by adopting this comprehensive methodological approach, the study aimed to provide a nuanced understanding of the relationship between diabetes mellitus and hypertension during pregnancy, offering valuable insights into the identification and management of at-risk populations. this methodology enables the exploration of both the direct effects of diabetes on hypertension risk and the potential interaction effects with other clinical and demographic variables, thereby enhancing the relevance and applicability of the findings to clinical practice. results the study analyzed data from 1,200 pregnant women diagnosed with diabetes mellitus, of which 800 had gestational diabetes mellitus (gdm) and 400 had pregestational diabetes (200 with type 1 and 200 with type 2 diabetes). the mean age of participants was 32 years, with an average body mass index (bmi) of 28 kg/m². among the cohort, 35% of the women developed hypertensive disorders during pregnancy. the prevalence of gestational hypertension was 20%, while preeclampsia was observed in 15% of the participants. notably, the incidence of hypertensive disorders was significantly higher in women with pregestational diabetes (45%) compared to those with gdm (30%). further stratification revealed that among women with pregestational diabetes, those with type https://doi.org/10.37547/ajbspi/volume03issue03-01 https://scholar.google.co.in/scholar?q= https://www.mendeley.com/search/?page=1&query= volume 04 issue

had a higher rate of hypertension (50%) compared to those with type 1 diabetes (40%). multivariate logistic regression analysis identified several key factors associated with an increased risk of developing hypertensive disorders. women with pregestational diabetes were found to have an adjusted odds ratio (or) of 2.5 (95% ci: 1.8–3.4) for hypertension compared to those with gdm, even after adjusting for age, bmi, parity, and family history of hypertension. poor glycemic control, indicated by an hba1c level greater than 6.5% in the first trimester, was a significant predictor of hypertensive outcomes (or: 1.9, 95% ci: 1.4–2.6). additionally, advanced maternal age (≥35 years) and higher bmi (≥30 kg/m²) were independently associated with increased hypertension risk, with ors of 1.7 (95% ci: 1.2–2.3) and 1.8 (95% ci: 1.3– 2.5), respectively. subgroup analyses further highlighted differences in hypertension risk based on the type of diabetes and glycemic control levels. women with poorly controlled type 2 diabetes (hba1c > 7.0%) had the highest risk of hypertensive disorders (or: 3.2, 95% ci: 2.1–4.8), while those with well-controlled type 1 diabetes (hba1c ≤ 6.5%) had a comparatively lower risk (or: 1.5, 95% ci: 0.9–2.4). among women with gdm, those who required insulin therapy were more likely to develop hypertensive disorders than those managed with diet and exercise alone (or: 2.1, 95% ci: 1.5–2.9). sensitivity analyses confirmed the robustness of these findings across different subgroups, with consistent patterns observed when stratifying by bmi categories and antihypertensive medication use. these results underscore the significant association between diabetes mellitus and hypertensive disorders in pregnancy, particularly among women with pregestational diabetes and poor glycemic control. the findings suggest that early identification and rigorous management of diabetes and other risk factors are crucial in reducing the risk of hypertensive complications in pregnant women. this study highlights the need for personalized care approaches tailored to the specific risk profiles of pregnant women with diabetes, to improve maternal and fetal health outcomes. discussion the findings of this study reveal a substantial association between diabetes mellitus during pregnancy and an increased risk of hypertensive disorders, such as gestational hypertension and preeclampsia. our results align with existing literature that highlights the heightened vulnerability of pregnant women with both gestational and pregestational diabetes to hypertensive complications. notably, the study demonstrates that women with pregestational diabetes, particularly those with type 2 diabetes, are at a significantly higher risk compared to those with gestational diabetes mellitus (gdm). this disparity may be attributed to the chronic nature of pregestational diabetes, which likely contributes to a more pronounced state of insulin

inflammation, factors that are well-recognized in the pathogenesis of hypertensive disorders. the increased risk observed in women with poorly controlled glycemic levels (hba1c > 6.5%) underscores the critical role of glycemic management in mitigating hypertension risk during pregnancy. hyperglycemia is known to exacerbate vascular damage and promote inflammatory pathways, which may predispose pregnant women to the development of hypertension. this study's findings suggest that stricter glycemic control, especially in the early stages of pregnancy, could potentially reduce the incidence of hypertensive disorders among this population. moreover, our results indicate that advanced maternal age and higher bmi are independent risk factors for hypertension, suggesting that both metabolic and demographic factors need to be considered when assessing the risk profile of pregnant women with diabetes. subgroup analyses reveal nuanced insights into the differential risks associated with the type of diabetes and glycemic control. women with type 2 diabetes, particularly those with poor glycemic control, exhibited the highest risk of hypertensive disorders, highlighting the need for targeted interventions in this subgroup. the finding that women with gdm requiring insulin therapy have a higher risk of hypertension compared to those managed with diet and exercise alone suggests that the severity of glucose intolerance may play a role in hypertensive outcomes. these observations emphasize the importance of individualized treatment strategies, including closer monitoring and tailored therapeutic approaches for women with higher risk profiles. our study’s strengths lie in its large sample size and comprehensive data collection, which allowed for a robust analysis of various risk factors. however, there are limitations to consider. the retrospective design may introduce selection bias, and the reliance on medical records could result in incomplete data. additionally, the study did not account for other potential confounding factors such as lifestyle behaviors and socioeconomic status, which may influence both diabetes management and hypertension risk. future research should aim to incorporate prospective designs and a more diverse range of variables to further elucidate the complex relationship between diabetes and hypertensive disorders in pregnancy. conclusion this study underscores the significant association between diabetes mellitus during pregnancy and an increased risk of hypertensive disorders, including gestational hypertension and preeclampsia. pregnant women with pregestational diabetes, particularly those with type 2 diabetes and poor glycemic control, are at a notably higher risk of developing hypertension compared to those with gestational diabetes mellitus (gdm). the findings highlight the importance of early screening, close monitoring, and effective https://doi.org/10.37547/ajbspi/volume03issue03-01

additionally, the study identifies advanced maternal age, higher bmi, and the severity of diabetes as critical factors influencing hypertension risk, emphasizing the need for personalized care approaches. by identifying these risk factors, healthcare providers can better target interventions to those most at risk, ultimately improving maternal and fetal health outcomes. future research should focus on prospective studies that include a broader range of variables to further clarify the mechanisms linking diabetes and hypertension in pregnancy and to develop more refined prevention and management strategies. reference 1. rani pr, begum j. screening and diagnosis of gestational diabetes mellitus, where do we stand.j clin diagn res. 2016;10(4):qe01-qe4. 2. 2. buchanan ta, xiang

(issn: 2771-2745) ability of the tannins to oxidize with a potassium permanganate solution. a weight of 1.0000 g of roots of common acorns, pre-ground to a fraction 1-2 mm in size, was weighed. the raw material was placed in a flask with a capacity of 250 ml and 50 ml of distilled water was added. the resulting mixture was heated in a water bath for 30 minutes at a temperature of 60-70°c with periodic stirring to ensure the extraction of tannins. after extraction, the mixture was cooled to room temperature and filtered through paper filters to remove mechanical impurities. quantitative analysis of the filtered extract was conducted. to create the acidic environment necessary for the reaction, 10 ml of extract was taken and 5 ml of 10% sulfuric acid solution was added to the titration flask. the extract was titrated with 0.1 n potassium permanganate solution until a stable pink color was obtained and stored for 30 seconds. the amount of potassium permanganate spent on titration was recorded. the obtained data was used to calculate the content of tannins in the raw material. the following formula was used for the calculation: t= 𝑉·𝑁·𝐾·𝑀 𝑚 · 100 where (v) is the volume of potassium permanganate solution used for titration (ml); (n) normal potassium permanganate solution (0.1 n); (k) coefficient of recalculation for tannins (0.004157); (m) the molecular weight of the douching agent equivalent; (m) the mass of the raw material being analyzed (g). as a result of the analysis, the proportion of tannins in the rhizomes of common horsetail was 1.19%. glycoside ratio determination improved methods have been developed for determining the concentration of glycosides in the roots of common juniper, including the stages of extraction, enzymatic hydrolysis, and spectrophotometric analysis. pre-dried and ground 1,0000 g of licorice rhizomes were weighed and placed in a flask with a capacity of 100 ml. 20 ml of 70% ethanol was added to the raw material. extraction was carried out in an ultrasonic bath at a temperature of 40°c for 30 minutes. after extraction, the mixture was filtered through paper filter and the extract volume was increased to 25 ml. the resulting extract was enzymatically hydrolyzed. for this purpose, 2 ml of β-glucosidase solution at a concentration of 0.1 mg/ml was added to 5 ml of the extract. the mixture was placed in a thermostat and incubated at 37°c for 1 hour. after hydrolysis was completed, 5 ml of 10% trichloroacetic acid solution was added to the reaction mixture to remove enzymatic proteins, which contributed to the precipitation of protein components. the suspension was centrifuged at a rate of 3000 rpm for 10 minutes, after which the liquid above the precipitate was used for spectrophotometric analysis. to determine the amount of glycosides, 2 ml of orthodihydroxybenzoic acid, acting as a reagent for phenolic compounds, was added to 2 ml of the obtained supernatant. the volume was increased to 10 ml of distilled water. the mixture was stirred intensively and left for 30 minutes to stabilize the color. the optical density of the solution was measured on a spectrophotometer at a wavelength of 410 nm. the concentration of glycosides was determined using a calibration curve constructed using a standard solution of rutin in the concentration range of 10-100 μg/ml. the following formula was used to calculate the concentration of glycosides in the raw material: g= 𝐶·𝑉 𝑡𝑜𝑡𝑎𝑙 𝑚 · 100 where (c) is the concentration of glycosides in the extract (mg/ml); (v) total volume of the extract (ml); (m) raw material mass (g). calculations have shown that the content of glycosides in the roots of the common acorns is 1.4%. results and discussion permanganatometric titration allowed for the determination of the content of tannins in the rhizomes of common acorns, which amounted to 1.19%. this method demonstrates high accuracy and reproducibility of results. an improved method for determining glycosides, including enzymatic hydrolysis and spectrophotometric analysis, ensured their reliability and effectiveness, and their content was reliably determined to be 1.4%. this method has a number of advantages over phenolic compounds, including high specificity and minimal side effects. the obtained results can be used in the standardization of methods for analyzing medicinal plant raw materials and in the development of new drugs, as well as in a detailed method of spectrophotometric determination of glycosides with calibration. determining the composition of tannins analysis method: the permanganate titration method was used to quantify the tannins. 1. dried and ground lion rhizomes weighed 1.0000 g. the raw material was placed in a 250 ml flask and 50 ml american journal of applied science and technology 25 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) of distilled water was added to it. the extraction was stirred periodically in a water bath at a temperature of 60-70°c for 30 minutes. the mixture was cooled to room temperature and filtered through a paper filter. for titration, 10 ml of extract was taken and 5 ml of 10% sulfuric acid solution was added to the flask. it was titrated with a 0.1 n solution of potassium permanganate (n = 0.1) until a stable pink color was obtained. the recorded volume of potassium permanganate solution (v = 11.4) ml. the content of tannins (t, %) was calculated using the following formula: t= 𝑉·𝑁·𝐾·𝑀 𝑚 · 100 here: ● v = 11.4 ml of potassium permanganate solution used for titration; ● n = 0.1 normal solution of potassium permanganate; ● k = 0.004157 recalculation coefficient for tannins; ● m = 1 molecular mass of the equivalent of tannins; ● m = 1.0000 g the mass of the raw material being analyzed, substituting the values, we get: т = 11.4·0,1·0.004157·1 1.0000 · 100 = 1,19 thus, the content of tannins in the roots of the common acorns is 1.19%. glycoside composition determination (spectrophotometric method) analysis method: a spectrophotometric method was used to determine the components of glycosides using enzymatic hydrolysis and calibration curves. stage 1. extraction. a 70% ethanol method was used to extract glycosides from licorice root, which ensures the effective extraction of hydrophilic and moderately lipophilic compounds. raw material preparation: ayira rhizomes are dried to a constant mass at a temperature of 40-50 °c, then ground to 1-2 mm. 2. drawer: 1.0000 g of crushed raw material was used for analysis, which was weighed on analytical scales with accuracy up to four marks after the comma. 3. adding a solvent: the drawer was placed in a heatresistant glass flask with a volume of 100 ml, and 20 ml of 70% ethanol was added to it. extraction: extraction was carried out in an ultrasonic bath (ultrasonic frequency 40 khz) at a temperature of 40°c for 30 minutes. ultrasound provides destruction of cellular structures and contributes to the release of target compounds into the solution. 5. filtration: after extraction, the mixture was filtered through a narrow porous paper filter into a 25 ml measuring flask. residues in the filter were washed with 70% ethanol to maximize the extraction of glycosides, and the volume of the extract was increased to 25 ml. the resulting extract was used for further analysis. stage 2. enzyme hydrolysis to break the glycosidic bonds and isolate aglycones, the extract was subjected to enzymatic treatment using the enzyme β-glucosidase, which possesses the ability to selectively hydrolyze β-glucosidic bonds. preparation of the enzyme solution: a solution of βglucosidase was prepared in distilled water at a concentration of 0.1 mg/ml. the solution was stored on ice and used for 2 hours after it was ready. 2. incubation: 5 ml of ethanol extract was placed in a 10 ml tube and 2 ml of β-glucosidase solution was added. to prevent evaporation, the tube was tightly closed. the mixture was incubated in a thermostat at 37°c for 1 hour. the incubation temperature and time were chosen based on the optimal conditions for enzyme activity. 3. stopping the reaction: after the completion of enzymatic hydrolysis, the reaction was stopped by adding 5 ml of a 10% solution of trichloroacetic acid, denaturing the protein and enzyme. 4. protein precipitation: the suspension was centrifuged in tubes at a rate of 3000 rpm for 10 minutes. after centrifugation, the protein precipitate settled to the bottom of the flask, while the liquid above the precipitate contains free aglycones. this liquid was used to react with the reagent. stage 3. reaction setting and optical density measurement. to determine the concentration of the released aglycones, a reaction was carried out with orthodihydroxybenzoic acid, which is a complexing agent stained with phenolic compounds. reaction: 2 ml of 0.1% ortho-dihydroxybenzoic acid solution was added to the liquid above the precipitate. the volume was increased to 10 ml of distilled water. the mixture was stirred intensively and left at room temperature for 30 minutes to stabilize the color. 2. optical density measurement: after color american journal of applied science and technology 26 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) stabilization, the optical density was measured at wavelength using a uv-vis spectrophotometer (e.g., shimadzu uv-1800) compared to the control solution 410 nm (distilled water with the addition of the reagent, but without extract). the optical density of each sample was compared to the calibration curve constructed on a standard rutin solution. stage 4. constructing a calibration curve. standard solution: the rutin solution was prepared at a concentration of 100 mcg/ml and diluted to obtain serial dilutions in the range of 10-100 mcg/ml. for each dilution of the standard solution, the same reaction was carried out with ortho-dihydroxybenzoic acid as with the sample. 3. measurement: the optical density of each sample was measured at a wavelength of 410 nm. 4. graph construction: optical density ((d)) values were introduced depending on the rutin concentration ((c), mg/ml). the equation of the calibration curve has the following form: d = 0.0123 c. stage 5. calculation of glycoside composition the experimentally measured optical density of the investigated extract was (d = 0.67). concentration was determined using the calibration curve equation: с = 𝐷 0.123 = 0.67 0.123 = 54.47mkg/ml. the total concentration of glycosides in the extract per raw material mass (m= 1.0000 g) was calculated using the following formula: g= 𝐶·𝑉total 𝑚 · 100 here: vtotal = 25 ml, we plug in the values: g = 54,47·25 1.0000 · 100=1.36% conclusions: a detailed method of extraction and enzymatic hydrolysis ensures the accurate determination of glycosides in the roots of the fir grass. the content of glycosides is 1.36%. this value is confirmed by the calibration curve and is considered reliable. preparation of a standard solution of rutin to prepare a standard rutin solution with a specific concentration, the following steps must be followed: 1. preparation of the starting material: use chemically pure rutin that meets pharmacopoeial standards. the rutin must be well-dried (if necessary, it is dried at 100-105 °c for 2 hours) and weighed with high accuracy. 2. weigh: weigh 10,000 mg of rutin on an analytical scale. this amount corresponds to the preparation of a standard solution with a concentration of 1 mg/ml (1000 mcg/ml) in 10 ml. 3. solvent: 70% ethanol is used as the solvent. ethanol effectively dissolves rutin, preventing its crystallization. 4. dissolve: place the rutin sample in a 10 ml measuring flask. add a small amount of 70% ethanol and dissolve the substance with constant stirring. if necessary, it can be slightly heated in a water bath to a temperature not exceeding 40 °c to accelerate the melting of the mixture. 5. delivery to the required volume: after the substance is completely dissolved, add 70% ethanol to increase the volume of the solution to 10 ml. concentration testing: the resulting solution has a concentration of 1 mg/ml. it can be used for the preparation of standard solutions of various concentrations by the method of sequential dilution. preparation of a series of standard solutions for constructing a calibration curve. 1. multiplication series: to construct a calibration curve, the standard rutin solution (1 mg/ml) is diluted as follows: take 1 ml (1 mg/ml) of the initial rutin solution and bring it to 10 ml with 70% ethanol in a measuring flask. obtained concentration: 100 mcg/ml. using a solution of 100 mcg/ml, we prepare the following solutions sequentially: apply 1 ml of 100 mcg/ml solution to 10 ml: concentration 10 mcg/ml. bring 2 ml of 100 mcg/ml solution to 10 ml: concentration 20 mcg/ml. 4 ml 100 mcg/ml solution to 10 ml: concentration 40 mcg/ml. 6 ml 100 mcg/ml solution to 10 ml: concentration 60 mcg/ml. 8 ml 100 mcg/ml solution to 10 ml: concentration 80 mcg/ml. the prepared solutions should be used for 24 hours. they should be stored in closed tubes in a dark place at a temperature of 4-8 °c. 3. optical density measurement for reactions and american journal of applied science and technology 27 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) construction with orthohydroxybenzoic acid. usage: each standard solution is used to determine the calibration curve. conclusion the study investigated the content of tannins and glycosides in the rhizomes of common fir and analyzed methods for their determination. the use of permanganate titration allowed for the determination of the content of tannins at a level of 1.19%. to quantify glycosides, a spectrophotometric analysis method has been improved, including the stage of enzymatic hydrolysis using β-glucosidase. the developed methodology ensured accuracy and allowed for the determination of the amount of glycosides in rosehip root at a level of 1.36%. the obtained results confirm the pharmacological significance of simple fir as a source of biologically active substances. the developed methods can be recommended for standardization and pharmacopoeial analysis of medicinal plant raw materials, as well as for further study of pharmacological properties and development of medicinal products. references state pharmacopoeia of the

hepatitis c khayrullaeva d.kh. tashkent medical academy, tashkent city, uzbekistan mamatyusupov m.kh. tashkent medical academy, tashkent city, uzbekistan received: 26 february 2025; accepted: 22 march 2025; published: 25 april 2025 abstract: this article describes the prevalence and clinical features of 105 patients with chronic hepatitis. as a result of the study, it was found that the disease is more common in women and the different picture of subjective or objective symptoms is higher in patients. keywords: chronic hepatitis, liver, virus, subjective sign, objective sign. introduction: relevance and importance of the topic. according to the world health organization (who), 3% of the world's population, or approximately 170 million people, are infected with the hepatitis c virus (hcv). according to the researched scientific analysis, the wide distribution of liver tissue damage caused by the virus, the high percentage of it becoming chronic and liver cirrhosis and liver tumor indicate that the disease is not only a medical, but also a social problem [1,2,5,8,9]. the disease in 80% of cases becomes chronic and undergoes constant mutations, the difficulties in creating a vaccine and the high cost of treatment make the disease a pressing problem in modern therapy and infectious diseases. acute and chronic forms of viral hepatitis are often asymptomatic, and laboratory tests are also observed in borderline values [2,3,4,5,10,11]. currently, much attention is being paid to the systematic study of the clinical and laboratory features of chronic viral hepatitis. however, the number of studies that can confirm this idea is extremely small, and the data they contain are unreliable. based on these considerations, the aim of our work is to assess liver function in patients with chronic viral hepatitis by determining clinical and laboratory markers and biochemical parameters. viral hepatitis c continues to be the most important medical and social problem worldwide. this is due to high morbidity, especially among young people, the severity of complications and the degree of chronicity. viral hepatitis c is the most common cause of hepatocellular carcinoma. chronic viral hepatitis c is one of the socially significant infectious diseases. the importance of this disease is determined by the high proportion of chronicity of acute hepatitis (up to 80% of cases), the ability of the hepatitis c virus to constantly mutate and the associated difficulties in creating a vaccine, the high cost of treatment [5, 7, 11]. in 2019, according to the world health organization (who), 71 million people worldwide were infected with the hepatitis c virus, and 350,000 to 500,000 people die each year. chronic viral hepatitis c is considered one of the leading causes of liver cirrhosis and the development of hepatocellular carcinoma. it is the clinical outcomes of hepatitis c that more often than other etiological factors lead to transplantation. according to various authors, 250-400 million people chronically infected with the hepatitis c virus are registered in the world. the relevance of the problem is also associated with the possible consequences of chronic viral hepatitis. it has now been proven that chronic hcv infection leads to progressive liver inflammation; in 20-30%, progression of liver cirrhosis with subsequent decompensation or formation of hepatocellular carcinoma is observed [3]. it has been established that in patients with hepatitis b, in 70-90% https://doi.org/10.37547/ajbspi/volume05issue04-10 https://doi.org/10.37547/ajbspi/volume05issue04-10 https://doi.org/10.37547/ajbspi/volume05issue04-10 https://doi.org/10.37547/ajbspi/volume05issue04-10 american journal of applied science and technology 44 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) of cases, hepatocellular carcinoma may develop at stages up to the development of liver cirrhosis [2]. the study of the mechanisms of pathogenesis of chronic viral liver diseases against the background of the growth of this pathology in the world is an urgent task of hepatology. the basis of liver damage in hcv infection is a combination of direct cytopathic and immune-mediated cellular damage induced by the virus [1]. it is believed that disruption of the liver structure with the development of necrotic and fibrotic changes in it is associated with the level of production of proinflammatory cytokines interleukin-6 and tumor necrosis factor alpha (tnf-a) [4]. it is known that tnf'α is involved in tissue destruction and reparation processes against the background of inflammation, and its elevated level is observed in viral and bacterial infections, oncological diseases and many inflammatory reactions. during an exacerbation of gastrointestinal diseases, the concentration of tnf'α in the blood serum exceeds the norm by an average of 10 times, and in some patients by 75–80 times [2,8]. methods the study included data on the results of clinical, laboratory and instrumental examinations of 105 patients diagnosed with chronic viral hepatitis. 67 (64.1%) of the patients were female, 38 (35.8%) were male, and their age ranged from 20 to 75 (mean 44.2±3.2) years. the results of the examination were assessed using a clinical-reference card (questionnaire). the study was approved by the members of the ethics committee established under the auspices of the bukhara medical institute. inclusion criteria for the study: patients with chronic hepatitis aged 20-75 years; persons who provided written consent for clinical, laboratory and instrumental examinations. exclusion criteria: alcohol or drug addiction, toxic hepatitis, alcoholic hepatitis, serious illnesses (uncontrolled arterial hypertension, type 2 diabetes mellitus in the decompensation stage, chronic heart failure iii-iv functional class, patients with myocardial infarction and stroke), pregnant and lactating women. to rule out alcoholic liver disease, a history (absence of regular alcohol consumption) was collected and screened using a special cage questionnaire [4]. during the study, a comparative assessment was performed with 60 healthy subjects (aged 20-65). in the process of diagnosing patients, anamnesis data were collected, laboratory and ultrasound examinations were used. abdominal ultrasound examination (assessing the size of the liver and spleen, the condition of the parenchyma, the extrahepatic bile ducts, the vascular pattern of the liver, identifying signs of portal hypertension: the presence of ascites, the diameter of the splenic vein > 10 mm, portal vein > 13 mm, splenomegaly, redrainage of the umbilical vein was determined by parameters and the following symptoms were noted: liver enlargement, increased echogenicity, relatively decreased liver density compared to the spleen (liverspleen index less than 1), decreased sound conductivity, poor visualization of the portal and hepatic veins. ultrasound elastography was performed in 105 patients to rule out fibrosis in liver parenchyma. biochemical tests of blood: alanine aminotransferase (alt) and aspartate aminotransferase (ast), γglutamyltranspeptidase (ggtp), alkaline phosphatase (if), total bilirubin, total protein and its fractions, blood clotting system activity were studied. the obtained data were statistically processed using the student's t-test, and the difference in results with p<0.05 was considered reliable results the ratio of women to men in our study was 1.3:1. the prevalence of chronic hepatitis by age is shown in table 1. table 1. description of the examined group of patients indicators main group n =105 control group n=60 men n

the working-age population. to assess the characteristics of clinical manifestations, the first task was to determine the range of leading symptoms that make up the essence of the disease. after that, each clinical and objective sign was analyzed. the frequency and incidence of clinical signs in sg were analyzed in detail. table 2. the rate of meeting subjective and objective symptoms in chronic

aerobiological monitoring, the importance of conducting palynological researches. it also provides information on the progress of aerobiological monitoring and scientific research in uzbekistan. in addition, it will be possible to get acquainted with the results of research on the relationship between the pollination season and meteorological factors of some plants that has an allergenic feature in the city of termez. keywords: lanzoni vpps 2010, pollen grain, allergy, pallinosis, palynology, monitoring, uzbekistan, light microscop. introduction: social production changes the environment by directly or indirectly influencing all its elements. this influence and its negative consequences have become especially pronounced with the increase in the scale of human activity and during the modern scientific and technological revolution [1]. the biological component is the most objective factor that can show how favorable the territory is for living, and helps to determine whether the situation in a particular region is dangerous for humans or, conversely, favorable for living. the deterioration of the ecological situation leads to an increase in the level of allergies [9,10]. pollen grains have the ability to adsorb various non-biological substances and particles on their surface and can carry various pollutants and dust over long distances. environmental changes lead to significant changes in the protein shell of pollen grains, which in turn leads to an increase in allergic reactions in humans [8]. environmental pollution leads to an increase in the period of pollination of plants. therefore, monitoring pollen of allergenic plants in cities is especially relevant [2,6]. numerous studies show the widespread occurrence of hay fever in the world, its important specific features. the distribution of pollen in the atmosphere, the differences in the species composition of pollen allergens, confirm the importance of studying the nature of the distribution of these allergenic plants in all natural zones and determining them in the aeropalynological regime. in the occurrence and development of hay fever, natural geographical conditions, the nature of the vegetation, the distribution of allergenic plants, the time and duration of their flowering, the quantitative and qualitative composition of pollen in the air play an important role [4]. aeropalynological monitoring of allergenic plants should provide an idea of the changes in pollen levels, allergenic plants and their pollen complexes for each region, depending on the season and weather conditions. a person must have 500 pollen grains for the disease to develop, that is, he must breathe air with a concentration of at least 25 pg/m3 [3]. to determine the concentration of pollen in the air, allergists of the international center for molecular allergology of uzbekistan and researchers of samarkand state university conducted aeropalynological studies. lanzoni vpps 2010 dust traps were installed throughout the republic for aerobiological monitoring. experts provide information on the results of the observations to the population, as well as to people https://doi.org/10.37547/ajbspi/volume05issue02-11 https://doi.org/10.37547/ajbspi/volume05issue02-11 https://doi.org/10.37547/ajbspi/volume05issue02-11

(issn: 2771-2745) suffering from hay fever, on the qualitative and quantitative composition of pollen of allergenic plants and fungal spores in the air of large cities during the period of pollination and spore formation every day (throughout the year) (information is provided via sms messages to the short number 3700 and via the website www.icma.uz). pollen monitoring was carried out in accordance with modern aeropalynological research methods [11]. aeropalynological studies, along with phenological and meteorological observations, are necessary for the development of the urban landscape. methods aerobiological monitoring in termez was carried out using a lanzoni vpps 2010 dust trap. the results obtained were analyzed quantitatively and qualitatively under an optical microscope, and the results were supplemented. as a result of the study, the concentration of plant pollen grains in the urban atmosphere was determined and systematically analyzed to the genus level. in addition, a pollen calendar of plants was compiled. advantages of the palynological method used in the study: 1. each pollen grain (p.g.) and spore can be identified to the family, genus, and sometimes species level due to its morphological characteristics. 2. higher plants produce a large number of pollen grains and spores, the shell of which falls to the surface of the earth and, while preserving its morphological characteristics, turns into rock and becomes a component of sedimentary deposits. 3. both pollen grains and the shell of spores (sporoderm) consist of a chemical composition, including sporopollenin, that is resistant to various physical and chemical influences. due to such a characteristic morphological structure, pollen grains and spores are easily transported by wind, water, birds, and insects. today, the influence of various abiotic factors on them is also being considered within the framework of aerobiological studies [11]. results and discussion pollen rain, its formation patterns, seasonal characteristics and daily dynamics of pollination of individual taxa, the role of pollen in the formation and development of hay fever, changes in the properties of pollen grains and the structure of pollen grains under the influence of a changing environment are currently among the problems that are actively discussed in the scientific literature[5]. modern aerobiological studies study the taxonomic composition of the aerospectrum in different regions, estimate the share of various taxa, including allergenic pollens. the time of onset and duration of pollination of taxa are determined; the influence of various meteorological parameters on the concentration of pollen in the atmosphere; aerobiological data are combined with data from allergological tests to determine the cause-and-effect relationship between the presence in the air of certain plant pollens and the occurrence of allergies, the taxonomic relationship of aeroallergens characteristic of the studied regions, and the time of their appearance in the air spectrum. [11]. the following taxa typical of the flora of termez demonstrate allergenic properties according to the list recommended by the allergology center: • alnus (a. glutinosa), • corylaceae ( corylus), • cupressaceae ( cupressus, juniperus, taxus), • oleaceae (fraxinus), • betula (b.pendula), • pinaceae ( picea, pinus), • quercus (q.ilex, q.cerris, q.robur, q.rubra), • poaceae, • rumex (r. acetosa, r. crispus, r. obtusifolius), • plantago (p. coronopus, p. lanceolata, p. major, p. media), •moraceae • amaranthaceae, • artemisia (a. annua, a. verlatorum, a. vulgaris), • ambrosia (a. artemisiifolia, a. elatier). the relationship between the pollen concentration of the above-mentioned plants in the atmosphere, pollen season and meteorological factors was determined as a result of palynological studies conducted in termez in 2024-2025, and the studies are ongoing. based on the results obtained, it is intended to draw conclusions about the risk of allergies and provide recommendations and suggestions for eliminating or reducing the risk. the data presented in figure 1 below represents the pollen calendar of these plants. american journal of applied science and technology 42 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) american journal of applied science and technology 43 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) figire 1. pollen calendar of termez city 2024. the beginning of pollination depends on the regions, or rather, on the meteorological factors in the regions. surkhandarya region is located on the southern part of the republic, and the high temperature and early start of the season affect the phenology of plants, as well as the pollination season [7]. from the picture above, it is clear that the flowering season of the plant begins from the last decade of february and lasts until early autumn. the pollination season is different for trees and grasses, with the pollination season of trees mainly falling in spring, and for grasses, it occurs in summer and autumn. taking into the account the timing of the onset of pollination and the waves of plant pollination identified by the author, it is possible to predict the periods of pollination of deciduous, coniferous, cereals and some weed groups of plants. conclusion pollen allergenicity monitoring is an old problem that requires new solutions. however, sometimes the will to innovate the field tends to overcome the necessity of standardised, comparable data. nowadays there is a wide range of different methods available for pollen monitoring, but their relative efficiency is sometimes unclear. this divergence of approaches is partly rooted in the geographical variability of pollen allergies and plant diversity, that makes it difficult to extend local results references chiara suanno, iris aloisi, stefano del duca. monitoring techniques for pollen allergy risk assessment, environmental research, volume 197, 2021, 111109 https://doi.org/10.1016/j.envres.2021.111109 asam et al. tree pollen allergens an update from a molecular perspective allergy clin. immunol.

"cobalt-30 neo" substance, were determined according to the applicable regulations. in developing the composition and technology of the capsules, the type and number of excipients were selected, taking into account the technological properties of the mass. the composition and technology of the "cobalt-30" capsule were developed, and all these aspects were thoroughly studied in the article. keywords: "cobalt-30 neo", dispersibility, bulk density, residual moisture, capsule drug form, excipients. introduction: one of the urgent and important issues of the modern pharmaceutical industry is to increase the solubility of drugs, control the concentration and rate of release of active substances from the drug form. in order to solve this problem, various excipients are used, as well as methods of incorporating drugs into nano-sized materials are being used. in particular, the cyclodextrin (cd) complex is increasingly attracting the attention of scientists among many nanoscale agents. nowadays, cyclodextrin molecules are widely used by scientists to create various drug forms. the use of cyclodextrin and its derivatives makes it possible to increase the stability of substances, reduce side effects, active substances to easily pass through biological barriers, and to achieve high effectiveness in small doses. today, a derivative of cyclodextrins with high solubility and drug solubilizing activity hydroxypropylγ-cyclodextrin (hp-γ-cd) is also widely used. in this regard, cobalt-30, a substance used in leukopoiesis and hepatitis diseases, was synthesized as a supramolecular complex compound with hp-γ-cd. the purpose of the work: to develop a capsule drug form with optimal composition and scientific basis based on the complex combination of cobalt-30 with hp-γ-cd. relevance of the topic. currently, among ready-to-use drugs produced on an industrial scale, capsule drugs take the leading place. the capsule form of the drug is precisely dosed, has a rapid effect on the body and is highly bio-efficient, and has the ability to prolong and control the action of the active substance. when choosing the composition and technology of certain capsules, it is of great practical importance to study the technological properties of the mass to be placed inside the capsule. also, the technological properties of the substance "cobalt-30 neo" have a significant impact on the choice of the type of drug, the composition of excipients and the technology of obtaining the drug. if the technological features of the substance, such as fractional composition, dispersibility, bulk density, and residual moisture, are within the standard limits, the capsule fills evenly with the substance, ensuring a consistent average capsule weight. moreover, the quantitative analysis meets the required standards, ensuring the stability of the capsule. experience part. the experiments were based on determining the physicochemical features and

(issn: 2771-2745) technological properties of the mass to be encapsulated. the structural mechanical properties of the substance, specifically, the shape and size of the particles, were determined according to the methods given in the section 2.9.37 "optical microscopy" of the state pharmacopoeia of the republic of uzbekistan. the size and shape of the particles are one of the main indicators that directly affect the technological properties of the mass to be encapsulated. physicochemical properties of particles were determined using an adf u300p microscope with a magnification of 10 to 600 times (figure 1). figure 1. magnified images of the substance "cobalt-30 neo" under an electron microscope looking at figure 1, it can be seen that the substance "cobalt-30 neo" is a polydisperse powder composed of various particles, and it is mainly composed of plateshaped irregular particles of similar length and width. at the next stage of the research, the technological properties of the substance "cobalt-30 neo" were studied, and the results of the fractional composition analysis are presented in table 1. the fractional composition of the substance was determined according to the method presented in the scientific literature. to determine the fractional composition, 100 g of substance was placed in a set of sieves of different diameters and then sieved. for this purpose, 100 g of mass was placed on the uppermost sieve and a mechanical oscillatory motion was created for 5 minutes. then the sieves were opened, the masses on the sieve were weighed individually with an accuracy of 0.01g, and the obtained results were written in the form of table 1. the ones that remained on the sieve were marked with (+), and the ones that passed through the sieve were marked with (-). fractional composition was expressed in µm, %. table 1 results of determining the fractional composition of the substance "cobalt-30 neo" (n=5) fractional composition: units of measure obtained

journal of applied science and technology (issn: 2771-2745) -180 1,79 based on the obtained results, it can be concluded that 54.75% of the substance consists of particles larger than +1000 µm. the proportion of -1000+500 µm particles is 25.7%, while the -500+355 µm fraction accounts for 11.7%. additionally, -355+250 µm particles make up 3.71%, -250+180 µm particles represent 2.35%, and particles smaller than 180 µm constitute 1.79%, as shown by the experimental results. it is known that if the particles of the substance and the mass to be encapsulated are of the same size or the difference between their sizes is not large, the amount of the active substance in the capsules filled during the encapsulation process and the average weight of the capsules will be the same and there will be minimal deviations from it. for the development of capsule drug forms, residual moisture, dispersibility and bulk density of the substance "cobalt-30 neo" were determined. the results are presented in table 2. table 2 results of determination of technological properties of "cobalt-30 neo" substance (n=5) examined parameters units of measure obtained results dispersibility g/s 3,4

"cobalt-30 neo", it is necessary to improve the fractional composition, dispersibility and bulk densities. various excipients were used for this purpose, which are widely employed in the pharmaceutical industry today. when choosing the composition of the "cobalt-30 neo" capsule, corn starch and microcrystalline cellulose were used as fillers, sodium croscarmellose and sodium starch glycolate as lubricants and dissolution enhancers, while calcium stearate and magnesium stearate were used as anti-friction agents. taking into account the humidity of the substance, it was first dried at 60⁰c for 1 hour and then ground in a mill. 6 different compositions were prepared with ground substance and various excipients approved for use in medical practice (table 3). table 3

presented in table 4, it can be seen that all compositions have different technological properties. the bulk density was 502-569 kg/m3, the natural deviation angle was 35-45 degrees. the residual moisture index in the mass to be encapsulated did not exceed 5% in all compositions and was found to be significantly improved compared to the initial substance and was in the range of 4.07-4.16%. however, the dispersibility of the prepared masses was relatively low in the 1,2,5-contents, and the samples containing corn starch were 3.85 g/s, 3.91 g/s, and 3.95 g/s, respectively. a mass with low dispersibility increases the likelihood of sticking to the hopper of the encapsulating machine. the disintegration time of the capsules was determined according to the method given in state pharmacopoeia of the republic of uzbekistan and did not exceed 20 minutes, as required by the pharmacopoeia. based on the above results, the technological properties of the studied compositions were analyzed. the number of excipients selected for composition № 3 demonstrated the most optimal indicators, including dispersibility, natural deviation angle, fractional composition, and residual moisture. to prove the scientific justification of the selected composition for the "cobalt-30 neo" capsule and to preliminarily assess its compliance with nd requirements, a comparative study of the

medicines not only for treatment but also for prevention is considered highly relevant. dietary supplements (biologically active food additives or bafas) are mainly used as preventive agents [3]. keywords: biologically active, preventive agents, scientific research. introduction: it is well known that for a long time, plant-based medications such as hawthorn and geranium collinum have proven to be effective cardioprotective agents [4]. these plants have been widely used not only in folk medicine but also in scientific research. numerous studies indicate that these plants are rich in various biologically active compounds, making them highly valuable in medicine. research objects. the research utilized hawthorn fruits (crataegus) and roots/rhizomes of geranium collinum, which grow in the republic of uzbekistan. research objective. the literature contains data on obtaining extracts from hawthorn fruits and the underground parts of geranium collinum [5]. however, despite numerous studies, no combined phytopreparation from these two plants currently exists. the goal of our research is to develop a technology for obtaining extracts from hawthorn fruits and geranium collinum roots and rhizomes, and on this basis, to produce a dietary supplement in capsule form named “cardioherb.” research results. during the development of extraction technology, several factors were considered: degree of raw material grinding, type of extractant, extraction method, chemical composition, etc. hawthorn fruits were ground into sizes of 1–2 mm, 3– 5 mm, and 7–8 mm. extracts were obtained using maceration, repercolation, and the method of vniif (all-union scientific research institute of pharmacy). the content of flavonoids—dihydroquercetin, luteolin, rutin, rosavin, quercetin, salidroside—was determined in the extracts using hplc (high performance liquid chromatography) (see figure 1). https://doi.org/10.37547/ajbspi/volume05issue06-05

introduction: epilepsy is a chronic disease that is accompanied by a violation of the functioning of the neurons of the central nervous system, characterized by seizures and loss of es hus in exchange for a dysbalance of the activity of the excitatory and inhibitory mediators of the brain [1, 2]. over the past few decades, more than 20 new antiepileptic drugs have been created, including escarbazepine acetate [3], perampanel [4] and ezogabin [5]. however, a large percentage of the population does not achieve a stable anticonvulsant effect with monotherapy [6], and about

(issn: 2771-2745) 30% of patients have refractory epilepsy and require a combination of treatment [7, 8]. in addition, many antiepileptic drug drugs have serious side effects [9, 10] and need lifelong treatment. therefore, the search for more selective and safer anticonvulsant agents is of particular interest. in the same point of view, several antiepileptic drugs of different approaches were studied for the development of [11-13]. the gamk-a receptor is a major target for a number of therapeutically important drugs such as barbiturates, steroids, anesthetics, and benzodiazepines [14,15]. 1,2,4-triazole derivatives have been found to exhibit many biological activities, including anticonvulsant [16, 17], anti-fungal [18-20], neurotrophic heterocyclic activity [21-24], anti-inflammatory [25-27], and antibacterial [28-31], based on experiments. the molecular structure and bioactivity of commercially available antiepileptic drugs are spatially long hydrophobic domains (typically phenyl rings), hydrogen-binding domains, and electron-donor fragments, elements required for high anticonvulsant activity. in addition, various other compounds with a 1,2,4-triazole moiety were found to have anticonvulsant properties in several animal models of epilepsy [32-35]. these findings prompted us to look for 1,2,4-triazole-based compounds with anticonvulsant activity and determine if the derived derivatives could act on the allosteric site of gaba-a receptors. the combination of 4-(6-phenyl-7h[1,2,4]triazolo[3,4-b][1,3,4]thiadiazine-3-yl) aniline conditionally (d-286) has been studied for its overall pharmacological activities and effects on vital organs. methods 4-(6-phenyl-7h-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazine3yl) is an aniline compound, with the substance twine80 as a solvent,

of the effect of the d-286 compound on cardiac electrophysiological indicators. the effect of the d-286 compound on the electrophysiological indicators of the heart scientific studies conducted in the study body weight 180-220 g. in laboratory white rats up to, schiller cardiovit was achieved by recording on the standard ii connection of the at-1 ecg hardware. for this purpose, the studied compound is evaluated for normal cardiac activity as well as antiarrhythmic activity in peripheral genesis disorders of the heart rhythm through arrhythmia models called through a chemical compound of arrhythmic nature. before the start of the experiment, an electrocardiogram (ecg) analysis was carried out on the standard connection ii in animals, and after that aconitin was sent to the tail vein in rats with a dose of 12-15 mcg/kg, which is called mixed in animals of all experimental groups-ventricular extrasystole. the formation of cardiac rhythm disturbances began in 1-2 minutes after the cessation of administration of aconitin, based on the rule. writing in ekg was conducted in 1; 3; 5; 10; 15 and 20 minutes after administration of aconitin. the substance under study was administered 60 minutes before oral aconitin administration at doses of 1.0; 10.0; 30.0 and 60.0 mg/kg, and at doses of 1.0; 2.0 and 10.0 mg/kg after arrhythmia caused by aconitin. all the experiments carried out were carried out in accordance with the control research scheme. the activity of the studied compound was assessed by its prevention of heart rhythm disturbances called aconitin. initially, the compound d-286 was used through the above-mentioned dosages and injection methods, the changes caused by its action on the normative electrophysiological indicators of the heart were recorded in the ii standard connection of the ecg for 60-70 minutes after the introduction of the substance. when the d-286 compound was administered orally at doses of 1.0; 10.0; 30.0 and 60.0 mg/kg, it was observed that the number of heart contractions in 50-60 minutes of the study decreased by an average of 30-35 times compared to the original. no changes were observed in pqrst tooth voltage, with the intervals of pq(r) and qrs (t) extending by 4-6% compared to the original. these results obtained indicate a decrease or slowdown in cardiac av and inter-ventricular conduction under the influence of the studied substance. it was observed that the substance studied showed anti-arrhythmia activity called by aconitin, corresponding to each dose, when administered orally at the doses noted above. heart rhythm disturbances in the form of polyphocals associated with cardiac conduction disorders occurred in the first minute after the introduction of aconitin at a dose of 1.0 mg/kg, and symptoms of recovery began to occur in these rhythm disturbances, which occurred from 11 minutes of the study, and a complete recovery of the rhythm was observed in 20-25 minutes. with aconitin exposure at doses of 10.0; 30.0 and 60.0 mg/kg, heart rhythm disturbances in the form of polyphocals occurred at 4.0; 2.0 and 1.5 minutes of the study, respectively, and from 10; 13 and 15 minutes began to develop signs of a begging of a disturbed rhythm. at a dose of 10 mg/kg, after 10 minutes of the study, the broken rhythm was completely restored according to all indicators, while at a dose of 30 mg/kg it was restored after 18 minutes, at a dose of 60 mg/kg, the rhythm recovery time was 5 minutes.also, rhythm disturbances caused by aconitin exposure when the substance studied was injected intravenously for treatment purposes-from 3-4 minutes of the study under the action of a dose of 1.0 mg/kg-to the recovery of the disturbed rhythm-this rhythm recovery took up to 8-10 minutes. signs of recovery of rhythm disturbances caused by aconitin exposure at doses of 2.0 and 10.0 mg/kg began to occur from 5 and 11 minutes of the study, and a complete recovery of rhythm occurred at 10 and 16 minutes. conclusion thus, the compound 4-(6-phenyl-7h-[1,2,4]-triazolo[3,4-b]-[1,3,4]-thiadiazine-3-yl)-aniline belongs to the group of triazole derivatives, according to stefanov on acute toxicity, class iv is among the less toxic compounds, and considering the presence of the sodium ion channel blocking property among these group compounds, the sinus, which was considered the first-order main controller of heart rhythm at a dose of 1.0 mg/kg studied during the experiment it can be concluded that nodini caused bradycardia in exchange for decreased activity. although few signs of bradycardia occur under the influence of the substance, it does not negatively affect the normative electrophysiological indicators of the heart. in addition, in cardiac arrhythmias called by aconitin, its activity against arrhythmias can be associated with the siege of na+ channels. references strine tw, kobau r, chapman dp, thurman dj, price p, balluz ls. psychological distress comorbidities and health

umbilical cord pathologies (literature review) tojiyeva nigina iskandarovna assistant, department of obstetrics and gynecology #1, samarkand state medical university, uzbekistan received: 17 june 2025; accepted: 13 july 2025; published: 15 august 2025 abstract: this review systematizes current knowledge about umbilical cord abnormalities (ucas) — a heterogeneous group of anomalies including length abnormalities, number of vessels, attachments, nodes, cysts, and vascular malformations. based on the analysis of scientific literature (2000–2024), the epidemiological data are presented: ucas occur in 15–35% of pregnancies, with single umbilical artery (sua) — in 0.5–5%, velmen insertion — up to 50% in monochorionic twins, and true nodes — in 0.3–1.2%. the review details complications: fetal growth restriction (fgr), chronic and acute hypoxia, antenatal death, risks during childbirth (vascular rupture in vasa praevia, asphyxia). particular attention is paid to early diagnostic methods: ultrasound with doppler (blood flow assessment, eap), color doppler mapping (velmen attachment), 3d/4d ultrasound in stic mode (nodes, spatial anomalies), ctg monitoring. differentiated management tactics are substantiated: from dynamic observation at low risk to planned cesarean section for vasa praevia or iugr. it is emphasized that timely diagnostics and an individualized approach reduce perinatal mortality and improve outcomes. keywords: umbilical cord cysts; varicose umbilical veins (varix); pregnancy complications; perinatal outcomes; fetal growth restriction (fgr); cord structure pathology. introduction: in addition to relatively common anomalies (entanglement, eap), there are rare umbilical cord pathologies that pose significant diagnostic and clinical challenges due to their low incidence, insufficient study, and potentially catastrophic consequences for the fetus. these include umbilical cord hypoplasia, varicose umbilical veins (varix), and true umbilical cord cysts. their prevalence does not exceed 1-3%, which complicates the accumulation of evidence [1, 2]. the objective of the review is to systematize data on epidemiology, classification (icd-10/icd-11), etiopathogenesis, impact on pregnancy and fetus, diagnostic methods, and principles of patient management with these rare pathologies based on an analysis of modern literature (2014-2024). methods a systematic search was conducted in pubmed, medline, scopus, cochrane library, and elibrary databases for the period 2014–2024. key words: "thin umbilical cord", "umbilical cord hypoplasia", "umbilical vein varix", "fetal intra-abdominal umbilical vein varix", "umbilical cord cyst", "rare umbilical cord abnormalities", "prenatal diagnosis", "pregnancy outcome", "fetal complications", "icd-10", "icd-11". original studies (prospective and retrospective cohort studies, case series), systematic reviews, metaanalyses, and clinical guidelines were included. publications in languages other than english and russian, without an abstract, and articles with a low level of evidence (reports of single cases without literature analysis, expert opinions without data) were excluded. results rare umbilical cord pathologies are characterized by low prevalence. hypoplasia of the umbilical cord (diameter < 8–10 mm in the second trimester or < 5–8 percentile) occurs in less than 1% of pregnancies and is coded in icd-10 as o69.8, and in icd-11 as ja20.2 [1,3,4]. umbilical vein varices (uvv) focal enlargement of the vein > 9 mm or > 50% of adjacent areas is diagnosed in 0.4–1.1% of cases (icd-10: o69.8/q27.8; icd-11: ja20.2/la8f) [2,5,6]. true umbilical cord cysts https://doi.org/10.37547/ajbspi/volume05issue08-03 https://doi.org/10.37547/ajbspi/volume05issue08-03

american journal of applied science and technology (issn: 2771-2745) (anechoic formations of embryonic origin) are detected in 0.1–0.5% of cases (icd-10: o69.8/q79.8; icd-11: ja20.2/lb11) [7,8]. hypoplasia is associated with wharton's jelly deficiency caused by impaired angiogenesis (decreased vegf, plgf) and mesenchymal differentiation. key risk factors: maternal smoking, thrombophilia, history of iugr [1,3,4]. uvv develops due to weakness of the venous wall, local elastin defects, increased venous pressure (fetal heart failure, arteriovenous shunts) or portal system thrombosis. pathogenesis includes turbulent blood flow → endothelial damage → risk of thrombosis/rupture [2,5,6]. true cysts are formed due to the persistence of embryonic structures: the allantois (urogynectic cysts) or the omphalo-mesenteric duct [7,8]. perinatal risks of rare umbilical cord pathologies are characterized by significant variability. in case of umbilical cord hypoplasia, there is a 3.5–5-fold increase in the risk of fetal growth restriction (fgr) (relative risk [rr] 3.5–5.0), which correlates with chronic hypoxia, manifested by an increase in the resistance index (ri) in the umbilical artery by 40% compared to the norm, as well as an increase in the risk of antenatal fetal death by 2–3 times [1,3,4]. varicose umbilical vein (uvv) is associated with antenatal death in 8–15% of cases, mainly due to thrombosis, while the risk of intrapartum rupture of the varicose node reaches 4–7% with fetal mortality exceeding 90% [2,5,6,13]. this pathology is also associated with the development of iugr in 24% of fetuses and a combination with congenital anomalies in 18-30% of cases [5,6]. true umbilical cord cysts diagnosed in the first trimester demonstrate an association with chromosomal abnormalities (mainly trisomy 18) in 15-20% of cases, while large cysts (>4050 mm) cause vascular compression leading to iugr in 12-18% of fetuses [7,8,14]. diagnostic algorithms are based on a comprehensive ultrasound examination. the key criteria for hypoplasia are a decrease in the umbilical cord diameter to less than 8 mm in the second trimester, a decrease in the volume of wharton's jelly and pathological doppler parameters (ri>0.8 in the umbilical artery, reverse blood flow in the venous duct), which are predictors of iugr [1,4]. uvv diagnostics is based on the detection of vein dilation greater than 9 mm in diameter, registration of turbulent flow during color doppler mapping (cdm) and an increase in peak systolic velocity (psv) greater than 40 cm/s, which is associated with a high risk of thrombus formation [2,5,6]. true cysts are identified as anechoic formations without internal blood flow during cdm, while the use of threedimensional ultrasound (3d-ultrasound) allows them to be differentiated from false cysts due to visualization of the epithelial lining [7,8]. as additional methods, fetal magnetic resonance imaging (mri) demonstrates high sensitivity (92%) in assessing portal system thrombosis in uvv and vascular compression by large cysts (>30 mm) [2,8], and invasive prenatal diagnostics (karyotyping/chromosomal microarray analysis) is recommended for uvv and first trimester cysts due to the frequency of aneuploidies reaching 18% [5,7]. modern scientific developments (2020–2024) are aimed at improving prognosis and diagnostics. a multiparameter risk index for uvv has been developed, including vein diameter, psv, and the presence of a thrombus, with an area under the roc curve (auc) of 0.89 [6], and for the early detection of complications in hypoplasia, a prognostic significance of a decrease in the umbilical cord diameter to less than 2.5 mm in the first trimester, associated with the development of iugr in 80% of cases, has been established [3,4]. technological innovations include the use of 3d power doppler for quantitative assessment of umbilical cord vascularization, where a decrease in the vascularization index correlates with the severity of iugr in hypoplasia (correlation coefficient r = 0.72) [4], as well as the use of the stic mode in 4d ultrasound, which increases the accuracy of diagnosing vascular compression by cysts by 35% [8]. in the field of biomarkers, a promising direction is the determination of the sflt-1/pigf ratio (>38) in uvv as an indicator of endothelial dysfunction [6], and the detection of elevated levels of alphafetoprotein (afp) and beta-subunit of human chorionic gonadotropin (β-hcg) in amniotic fluid in cysts associated with trisomy 18 [7]. differentiated tactics are based on the pathogenetic features of each nosology. in case of hypoplasia, intensive monitoring is required (dopplerometry 2 times a week, ctg from 28 weeks), and the development of blood flow disorders requires early delivery by cesarean section at 34–37 weeks [1,4]. management of uvv includes planned operative delivery at 34–36 weeks to prevent thrombosis and rupture, supplemented by daily ctg monitoring and weekly doppler [2,5,6]. for large true cysts (>50 mm), delivery at 36–38 weeks is recommended if there are signs of vascular compression or iugr [7,8]. american journal of

cohort studies and systematic reviews of the last decade, emphasizing the need for personalized risk management [1–8,14]. conclusion rare umbilical cord pathologies (hypoplasia, umbilical vein varices, true cysts), although occurring in less than 1-3% of cases, are significant causes of perinatal morbidity and mortality. their timely prenatal diagnosis using modern ultrasound technologies (including doppler and 3d/4d) and fetal mri is critically important. the pathogenesis of many of these conditions requires further study. pregnancy management should be based on a thorough assessment of fetal risks using all available diagnostic tools. in cases of uvv and progressive hypoplasia with iugr, planned early delivery by cesarean section is indicated. further studies should be aimed at identifying biomarkers, clarifying the genetic basis and developing standardized protocols for monitoring and delivery to improve perinatal outcomes. references hasegawa j, et al. umbilical cord

cardiovascular diseases djumaev alohiddin umirzakovich assistant of department of anatomy, zarmed university, samarkand, uzbekistan received: 24 december 2024; accepted: 26 january 2025; published: 28 february 2025 abstract: the article examines the latest advances in the study of the anatomy of the heart and blood vessels at the cellular level, as well as their impact on the treatment of cardiovascular diseases (cvd). it provides a detailed description of the various types of cells that make up the cardiac muscle and blood vessels, their functions, and their roles in the development of pathologies. modern research methods, such as high-resolution electron microscopy and gene editing technologies, are highlighted for their potential to open new avenues in cvd treatment. the article emphasizes the importance of cellular anatomy for understanding the pathophysiology of cvd and discusses the possibilities for applying the obtained data in clinical practice. keywords: cardiovascular diseases (cvd), anatomy of the heart, cellular anatomy, cardiac myocytes, endothelial cells, gene editing, crispr/cas9, research technologies, pathophysiology, myocardial regeneration. introduction: cardiovascular diseases (cvd) remain one of the leading causes of mortality worldwide. statistical data on the prevalence and mortality of cvd: 1. prevalence: according to the world health organization (who) data from 2021, approximately 523 million people worldwide suffer from cardiovascular diseases. this number is rapidly increasing each year due to factors such as an aging population and declining lifestyle choices. 2. mortality: in 2021, more than 17.9 million people died from cvd, accounting for about 32% of all deaths globally. this makes cvd the leading cause of death, surpassing cancer and other diseases. 3. regional variations: high mortality rates from cvd are observed in lowand middle-income countries, while high-income countries are experiencing a trend toward reduced mortality due to advancements in medical technology and lifestyle improvements. scientific developments and news in the study of cvd: 1. genomic research: recent studies indicate that genetic markers can predict the risk of developing cvd. research using genome-wide association methods has identified several genes associated with an increased predisposition to heart diseases. 2. cellular anatomy and regeneration: research in cardiac cellular anatomy shows that specialized subtypes of cardiomyocytes have unique characteristics affecting heart function and disease development. work on tissue engineering and cellular therapy continues, aiming to restore damaged heart tissue (gao et al., 2020; jiang et al., 2023). 3. influence of the microbiome: studies show that the gut microbiome can significantly impact cardiovascular health. certain bacteria and their metabolites can have both protective and harmful effects on the cardiovascular system. 4. technological advancements: the development of new imaging methods, such as 3d models of the heart and coronary vessels, provides more detailed insights into pathological changes and contributes to more precise treatments. crispr/cas9 is a revolutionary gene-editing technology that allows scientists to make precise changes to the dna of living organisms. it emerged from the study of the adaptive immune system in bacteria, which use this system to protect against viruses. https://doi.org/10.37547/ajbspi/volume05issue02-10 https://doi.org/10.37547/ajbspi/volume05issue02-10 https://doi.org/10.37547/ajbspi/volume05issue02-10 https://doi.org/10.37547/ajbspi/volume05issue02-10 american journal of applied science and technology 38 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) key components of crispr/cas9: 1. crispr (clustered regularly interspaced short palindromic repeats) — these are segments of dna that consist of arrays of repeating sequences, interspersed with "spacers" — sequences obtained from viral dna. these spacers serve as "memories" for bacteria, allowing them to recognize viruses during subsequent attacks. 2. cas9 — this is a nuclease protein capable of cutting double-stranded dna. it works in conjunction with a molecule of rna called grna (guide rna), which directs cas9 to the specific dna sequence. how it works: 1. designing grna: researchers develop grna that is complementary to the target dna they want to alter. 2. targeting dna: grna binds to cas9 and guides it to the desired area of dna, where a cut occurs. 3. cutting dna: cas9 creates a break in both strands of the dna. 4. dna repair: after the cut, the cell attempts to repair the break. in this process, targeted changes can be introduced by adding or removing specific sequences using approaches such as base substitution or inserting new dna segments. applications of crispr/cas9: 1. medical research: crispr/cas9 is actively used to study genes associated with diseases and to test hypotheses about gene functionality. 2. gene therapy: the technology shows potential for treating hereditary diseases such as sickle cell anemia and cystic fibrosis by correcting mutations. 3. oncology: researchers are exploring the application of crispr for editing genes in cancer cells, which could lead to more effective treatment methods. 4. agriculture: crispr/cas9 is used to create genetically modified plants and animals, enhancing their resistance to diseases, increasing yields, or improving nutritional properties. ethical and legal issues: while crispr/cas9 opens many possibilities, its use also raises a number of ethical and legal questions, especially regarding editing human embryos and gene flow in the wild. it is essential to develop appropriate international norms and regulations for the safe and ethical application of this technology. cardiovascular diseases (cvd) remain one of the leading causes of mortality worldwide. understanding the anatomy of the heart and blood vessels at the cellular level opens new approaches to the treatment and prevention of these diseases. in recent years, research on cellular anatomy, molecular mechanisms, and the dynamics of heart and vessel cells has led to significant discoveries. this article examines key aspects of the anatomy of the heart and blood vessels and their impact on clinical practice. the heart consists of three main layers: the epicardium, myocardium, and endocardium. the myocardium, or cardiac muscle, is the thickest layer and primarily consists of cardiac myocytes, which have unique properties enabling them to contract. each cardiac cell contains specialized structures, such as intercalated discs, which ensure efficient transmission of electrical signals and coordinated heart contractions (zhou et al., 2018). the heart contains several types of cells: 1. cardiac myocytes responsible for the contraction of the heart. 2. pacemaker cells include the sinoatrial node and atrioventricular node, playing a key role in generating and conducting electrical impulses. 3. fibroblasts provide structural support and participate in repair processes. 4. endothelial cells form the inner layer of coronary vessels and play a vital role in maintaining homeostasis and vascular function. studying the cellular anatomy of the heart provides new insights into the pathophysiology of cvd. for instance, changes in the function and number of endothelial cells can lead to atherosclerosis and ischemic heart disease. research indicates that endothelial dysfunction is associated with chronic inflammation, contributing to the progression of cvd (ross, 1999). cardiac myocytes can undergo damage during ischemia, leading to the replacement of functional tissue with scar tissue. this results in impaired cardiac function and increases the risk of heart failure. current studies focus on restoring myocytes through stem cell therapy or gene therapy, indicating the potential of these methods in clinical practice (gao et al., 2020). modern technologies, such as high-resolution electron microscopy and 3d scanning, allow for a deeper understanding of the cellular structure of the heart. for example, recent studies have shown that myocytes can have different subtypes with unique functional properties. these differences may explain individual responses to treatment and predisposition to diseases (eckhart et al., 2021). in addition, the use of crispr/cas9 gene editing technology opens up new possibilities for correcting genetic defects associated with cardiovascular american journal of applied science and technology 39 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) diseases. research indicates that editing genes responsible for the metabolism of myocytes can improve their function and promote regeneration (jiang et al., 2023). conclusion the anatomy of the heart and blood vessels at the cellular level is key to understanding cardiovascular diseases and their treatment. new discoveries in cellular anatomy open avenues for developing new therapies that can transform the approach to treating cvd. ongoing research continues to provide insights, and it is essential to keep abreast of new advancements that may significantly improve treatment outcomes and the quality of life for patients with cardiovascular diseases. references zhou, y., et al.

tashkent pharmaceutical institute, master's student in the specialty "technology of medicines and preparations", uzbekistan received: 14 april 2025; accepted: 10 may 2025; published: 17 june 2025 abstract: this article provides information about medicinal plants used in medicine against diabetes, as well as in its prevention, and remedies, compositions, substances obtained on their basis, and their technologies. during the research, the results of studying dozens of representatives of local medicinal plants and their individual properties, as well as the properties of their collections, indications for use, in the treatment of diabetes mellitus, the beneficial properties of medicinal plants and collections, and their technological properties are presented. keywords: diabetes, sugar content, glucose, insulin, cumulative, diet, metabolism, extract, phytotea, bioactive supplement, technology, medicinal plants. introduction: diabetes mellitus is a metabolic disorder characterized by a decrease in insulin levels in the blood and an increase in glucose levels. in the treatment of diabetes, antidiabetic drugs are of great importance. one of the important directions in medicine is the use of herbal preparations with mild effects, low side effects, and high effectiveness. for the prevention and treatment of diabetes, medicinal plants containing a number of biologically active substances are used. in developed modern medicine, herbal remedies used in the treatment of diabetes mellitus are of great importance due to their relative harmlessness, healing properties, including normalizing blood glucose levels, anti-obesity, and other properties. plant preparations and formulations with an antidiabetic effect are used to stimulate insulin production processes and facilitate digestion[1]. in the field of endocrinology, various blood sugarlowering agents are recommended as an antidote to diabetes and concomitant diseases caused by a decrease in insulin levels. depending on the technology of obtaining medicinal plant preparations and complexes against diabetes mellitus, various extracts can be obtained from ground plant materials. these extracts contain several medicinal substances isolated using various separators, and also in the crushed plant material during the preparation of the compositions, biologically active substances are fully present. purpose of the research: development, analysis, generalization of drugs, biologically active substances, and kits with antidiabetic effects and their technologies. methods when obtaining extracts from medicinal plants, the selection of the extractant is carried out depending on the type of plant, the part of the raw material, and the groups of biologically active substances contained in it. usually, various potent ethyl alcohol, water, essential oils, or other separators are used in work processes. extraction processes utilize maceration, percolation, and ultrasonic extraction methods [2]. one of the promising methods is obtaining extracts using ultrasonic extraction. in ultrasonic extraction, the plant is soaked in a separator and subjected to https://doi.org/10.37547/ajbspi/volume05issue06-04 https://doi.org/10.37547/ajbspi/volume05issue06-04 american journal of applied science and technology 16 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) ultrasonic exposure, in which the plant tissues are subjected to high-speed vibrations under high pressure and vacuum due to the phenomenon of cavitation. as a result, organic substances in tissues, including substances that can be released into the excretory medium, are released into the excretory medium, i.e., the extraction process occurs. with this method, it is possible to carry out extraction processes both in the laboratory and on an industrial scale. below, taking into account the demand and interest in medicines based on medicinal plants, including antidiabetic preparations and kits, information is provided on the main antidiabetic drugs and medicinal plant-based kits, their mechanisms of action, indications for use and features of use, technologies for obtaining them, and the use of products obtained from various medicinal plants in medical practice. results below are several plants, assortments, and biologically active supplements used in the treatment of diabetes mellitu beans (galega officinalis) a rhizomatous perennial herbaceous plant of the legume family, the aerial part of which is used in folk medicine for the treatment of snake bites, infections, edema, as well as for milk loss in breastfeeding women. in modern medicine, biologically active additives with antidiabetic, diuretic, diaphoretic, lactogenic, and anthelmintic effects are produced from it. properties of medicinal peas: helps reduce blood sugar levels, normalizes metabolism, restores kidney function, gently removes excess fluid from the body, stimulates milk production in nursing mothers, eliminates inflammation, and fights infections. beans are also included in antidiabetic formulations[5]. bean peel (phaseolus) is a typical genus of annual plants of the legume family, with about 97 species found in warmer regions of the world. in addition to proper hypoglycemic properties, it has antiinflammatory and anti-rheumatic, as well as diuretic and antibiotic effects. they dissolve stones in the bladder and kidneys, lowering blood pressure. due to the high content of valuable substances in bean pods, they are widely used for medicinal purposes. medicinal and beneficial properties of bean peel: reducing blood sugar levels, fighting excess weight, eliminating hypersensitivity and hypertension, anti-rheumatic effect, diuretic, removal of kidney stones, elimination of skin diseases, treatment of chronic pancreatitis and cardiovascular pathologies. in medicine, decoctions and infusions are made from bean peel, and it is also included in antidiabetic formulations. use in diabetes mellitus (when sugar levels increase), at home. the peels are ground into powder using a coffee grinder and 400 ml of boiling water is poured over 50 g of raw material. after 12 hours of infusion, take 120 ml before meals. safflower (salvia) or sage is a large genus of perennial herbaceous plants and shrubs belonging to the lamiaceae family. preparations made from the aerial parts (leaves and flowers) of medicinal sage have a sugar-lowering, anti-inflammatory, astringent, antiseptic, hemostatic, softening, and diuretic effect, reducing sweating. mavrak is also used in the form of a decoction or infusion for stomatitis, bleeding gums, as a astringent and antiseptic for rinsing the mouth in tonsillitis, and in the form of sprinklers for gynecological diseases. the medicinal sage plant inhibits lactation in nursing mothers and has a positive effect on gastritis, colitis, stomach ulcers, meteorism, and gallbladder inflammation. it has been established that sage extract helps reduce blood glucose levels in rats with type 1 diabetes by activating a specific receptor. when these receptors are activated, they can cleanse the blood of excess free fatty acids. this improves insulin sensitivity. another study on mice with type 2 diabetes showed that sage tea has the same effect as metformin, which regulates blood sugar levels in people with the same disease[4]. dandelion (taraxacum) is the most popular species of the dandelion genus of the dandelion family. it is a perennial herbaceous plant, reaching a height of 10-40 cm. its distribution range extends throughout the cis, except for the far north. the flowers, leaves, and roots of dandelion are used in medicine as a healing remedy. the presence of bitter glycosides, taraxerolic compounds, and other substances in the composition of dandelion root has been established. its roots are also a sugar-lowering, choleretic, appetite-stimulating, and gastric-inducing compound tea. antihyperglycemic, antioxidant, and anti-inflammatory properties of dandelion helped in the treatment of patients with type ii diabetes mellitus. the roots of the plant contain soluble fiber (inulin). moving throughout the body in an undigested form, it helps slow down the absorption of sugar into the bloodstream by improving long-term control of blood sugar levels [3]. stevia (stevia) is a genus of perennial plants belonging to the asteraceae family, comprising approximately 260 herbaceous and shrub species that grow mainly in the americas. crushed leaves of honey stevia have long been used as a natural sweetener, and now as a sugar substitute due to the growing need for lowcarbohydrate and low-sugar diets. plant leaves, their aqueous extract, and isolated glycosides (stevioside american journal of applied science and technology 17 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) and rebaudioside) are typically used as sweeteners. stevia leaves are 30 times sweeter than sucrose, and the isolated steviazides are 250-300 times sweeter. unlike artificial sweeteners (such as cyclamate and saccharin), stevia is not only not carcinogenic but, on the contrary, very beneficial. stevia is low in calories, does not contain glucose, and therefore is absorbed without the help of insulin, which is very important for diabetics [6]. ginko biloba (ginko biloba) is currently the only representative of the gymnosperm family of the ginkgo family. the tree reaches a height of up to 40 m and a diameter of up to 1 m; young seedlings resemble some coniferous trees. it grows wild only in some parts of china. it is cultivated in southern crimea and on the black sea coast of the caucasus. extract obtained from the leaves of ginco biloba is used in medicine to improve the function of small blood vessels. it is also widely used for improving brain function, diabetes, and other purposes [7-8]. cichorium intybus is a perennial herb with a thick root, belonging to the asteraceae family. it is used as a medicinal plant and among the people as a spice, as well as a substitute for coffee. the famous abu ali ibn sina used sachratqi to treat diseases of the gastrointestinal tract and eyes, eye inflammation, and gout. in modern medicine, sachratqi has found a wide variety of applications due to its beneficial medicinal properties (calming, sugar-lowering, astringent, choleretic, diuretic, anti-inflammatory, antipyretic, anthelmintic properties). the anti-diabetic and antiobesity effect of chicory is valuable due to the high content of the high-molecular-weight polysaccharide inulin in its roots. it is inulin that helps reduce blood sugar levels, improve metabolism and digestion, therefore, all its properties are considered important in the complex prevention and treatment of diabetes. phytodiabetol syrup 250ml. produced in russia (bioinventika llc). use: in

active supplements are important in the treatment of diabetes. they are lighter and harmless compared to synthetic agents, do not harm the body, and allow their use in patients in need of constant medications, such as diabetes. in the treatment of diabetes, it is possible to use a single plant product or several plant groups. plant-based phytopreparations recommended for the treatment of diabetes have some drawbacks. their weak effect and limited effectiveness in acute cases necessitate their combination with other treatment methods when necessary. phytotherapy is constantly developing, increasing the scope and interest in its use due to the accumulated experience and positive results of treatment. references https://med24.uz/ru/bolezn/saxarnyy-diabet hasanov.j.h.,

manufacturing, printability, formulation stability, material compatibility. introduction: three-dimensional (3d) printing has emerged as a transformative technology in the pharmaceutical field, offering the potential for personalized drug delivery systems (dumpa et al., 2021; tracy et al., 2023; wang et al., 2023). among the various 3d printing techniques, semi-solid extrusion (sse) is particularly advantageous for drug fabrication due to its ability to process a wide range of materials, including viscous formulations and temperaturesensitive drugs (seoane-viaño et al., 2021; govender et al., 2021). sse 3d printing involves extruding a semisolid material through a nozzle to create a 3d object, allowing for precise control over the shape, size, and internal structure of the final product (mazarura et al., 2022; johannesson et al., 2021). a critical aspect of sse 3d printing is the material delivery system, typically involving cartridges that hold the semi-solid formulation. traditionally, single-use cartridges have been employed, raising concerns about increased plastic waste and environmental impact (elliott et al., 2020; cowan et al., 2021). in response to these concerns, reusable cartridges have been introduced as a more sustainable alternative. however, the usability of these reusable cartridges in the context of pharmaceutical applications, where stringent hygiene and quality control are paramount, requires thorough evaluation (parhi, 2021). this study aims to evaluate the usability of reusable cartridges in sse 3d printing for drug fabrication. it assesses the ease of use, cleaning efficiency, material compatibility, and print quality achievable with reusable cartridges, comparing them to single-use counterparts. the findings will provide valuable insights into the potential of reusable cartridges to enhance the sustainability of 3d-printed pharmaceuticals without compromising product quality or safety. methods the study involved a comparative evaluation of reusable and single-use cartridges in sse 3d printing. the following methods were employed: 1. materials: a range of semi-solid formulations american journal of

2. 3d printing system: a commercially available sse 3d printer was used, equipped with both reusable and single-use cartridge systems. 3. usability assessment: o ease of use: the ease of filling, assembly, and disassembly of both cartridge types was evaluated through user trials with trained technicians. o cleaning efficiency: a standardized cleaning protocol was developed, and the effectiveness of cleaning procedures for reusable cartridges was assessed using visual inspection and residual material analysis. o material compatibility: the chemical compatibility of cartridge materials with the selected formulations was assessed to ensure no degradation or leaching occurred. o print quality: the dimensional accuracy, uniformity, and structural integrity of printed objects were evaluated using techniques such as microscopy and texture analysis. fig. lessons to learn for 3d printing of drug products by semisolid extrusion (sse) american journal of applied science and technology 3 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) 4. regulatory considerations: the study considered the regulatory perspectives on 3d printing in pharmaceuticals, particularly regarding the use of reusable components and potential crosscontamination risks (khairuzzaman, 2018). results the results of the study indicate the following: • ease of use: reusable cartridges were found to be slightly more complex to assemble and disassemble compared to single-use cartridges. however, with proper training, the process was manageable. • cleaning efficiency: the established cleaning protocol effectively removed residual material from the reusable cartridges, with no significant carryover observed. • material compatibility: the cartridge materials exhibited good compatibility with the tested formulations, showing no signs of degradation or leaching. • print quality: the print quality achieved with reusable cartridges was comparable to that of singleuse cartridges, with no significant differences in dimensional accuracy, uniformity, or structural integrity. discussion the findings suggest that reusable cartridges offer a viable alternative to single-use cartridges in sse 3d printing for drug fabrication. while there may be a slight increase in complexity regarding assembly and disassembly, the cleaning protocols can be effective in preventing cross-contamination. the adoption of reusable cartridges can significantly reduce plastic waste, aligning with the growing emphasis on sustainability in pharmaceutical manufacturing (kasznik & łapniewska, 2023). the economic benefits of reduced material consumption and waste disposal costs further support their implementation. it is crucial to adhere to stringent cleaning and sterilization procedures to mitigate the risk of crosscontamination, especially when processing different drug formulations. further research is needed to optimize cartridge design and cleaning protocols, and to address long-term durability and performance. conclusion reusable cartridges present a promising approach to enhance the sustainability of sse 3d printing for drug fabrication. with proper handling and cleaning procedures, they can effectively replace single-use cartridges without compromising print quality or safety. the adoption of this technology can contribute to a more environmentally friendly and economically viable approach to personalized medicine. references dumpa n, et al. 3d printing in personalized drug delivery: an

(ucas) are a heterogeneous group of anomalies that include deviations in length, number of vessels, type of attachment, presence of nodes, cysts and vascular malformations. despite the fact that many ucas have no clinical consequences, some types are associated with an increased risk of fetal growth restriction (fgr), hypoxia, birth asphyxia, stillbirth and the need for emergency operative delivery [1, 2]. the prevalence of ucas in the population varies, reaching significant numbers, which emphasizes the relevance of the problem for perinatology [3, 4]. modern methods of prenatal diagnostics, primarily ultrasound, play a key role in early detection and determination of pregnancy and childbirth management tactics [5, 6]. the purpose of the review: to systematize modern data on the prevalence, diagnosis, complications and management tactics of pregnant women with various umbilical cord abnormalities. methods an analysis of scientific literature data published for the period 2000-2024 was conducted using the pubmed, medline, scopus, cochrane library, and elibrary databases. key words: "umbilical cord pathologies", "umbilical cord anomalies", "umbilical cord entanglement", "true cord knot", "velmen insertion of the umbilical cord", "diagnosis of umbilical cord pathologies", "pregnancy complications with umbilical cord anomalies". systematic reviews, meta-analyses, randomized controlled trials, large cohort studies, and clinical guidelines were selected. results the overall incidence of ucas, according to ultrasound and pathological studies, ranges from 15% to 35% of all https://doi.org/10.37547/ajbspi/volume05issue08-02 https://doi.org/10.37547/ajbspi/volume05issue08-02 https://doi.org/10.37547/ajbspi/volume05issue08-02

(issn: 2771-2745) pregnancies [3, 7]. cord entanglement around the fetus's neck is the most common anomaly, occurring in 21-34% of term births, with multiple entanglements recorded in 2-8% of cases [1, 8]. single umbilical artery (sua) occurs with a frequency of 0.5-1% in singleton pregnancies and up to 5% in multiple pregnancies [2, 9]. in 20-30% of cases, sua is combined with other congenital fetal anomalies (cardiovascular, genitourinary, gastrointestinal tract, central nervous system) or chromosomal pathologies (trisomy 18, 13) [2, 10, 11]. velmen (membranous) insertion of the umbilical cord is observed in approximately 1% of singleton pregnancies, but its frequency increases to 15% in multiple pregnancies and up to 50% in monochorionic twins [12, 13]. true umbilical cord knots are less common, occurring in approximately 0.3-1.2% of pregnancies, but their clinical significance is high [14]. short umbilical cord (<35-40 cm) 4-6%, long umbilical cord (>70-80 cm) 5-7% [1, 15]. umbilical cord cysts (true and false) are detected in 0.4-3.4% of cases [16]. intrauterine growth retardation (especially with a single umbilical artery without associated anomalies, velmen attachment, thrombosis) is one of the common antenatal complications in umbilical cord pathologies [2, 9, 12]; chronic fetal hypoxia; spontaneous abortions (more often with early detection of sua or multiple cysts) [16] also occur in various organic pathologies of the umbilical cord. antenatal fetal death occurs with true knots, thrombosis, severe varicose veins, tight multiple entanglement [14, 17]. acute fetal hypoxia/asphyxia during labor occurs with tension of a short umbilical cord, tightening of a true knot, tight entanglement, prolapse of the umbilical cord [1, 8, 14]; placental abruption is the most serious complication that occurs with a short umbilical cord or tension with a velmen insertion [12]; rupture of the umbilical vessels with fatal bleeding in the fetus is most typical for a velmen insertion, especially with vasa previa [12, 13]; a prolonged course of the second stage of labor occurs due to a short umbilical cord, which is expressed in the need for an emergency cesarean section [1, 8]. children born with these pathologies have an increased risk of low scores on the apgar scale, an increased need for neonatal resuscitation, and they can also develop hypoxic-ischemic encephalopathy and the worst stillbirth [1, 14, 17]. the risk of perinatal mortality with a true umbilical cord knot increases by 4 times [14]. modern methods of examination and early detection of umbilical cord pathologies are intended to prevent these complications. standard 2d ultrasound (ii trimester, 18-22 weeks) is the main screening method. it allows diagnosing vascular pathology (assessment of the number of vessels in the cross-section), cysts, attachment anomalies (especially with a thorough examination of the placental disk), length (indirectly by the presence of loops, their number), varicose veins [5, 6, 9]. color doppler mapping (cdm) and power doppler (pd) are new methods, especially in the conditions of uzbekistan. these methods are critically important for confirming vascular anomalies, diagnosing velmen attachment (visualization of vessels running in the membranes), assessing blood flow in the umbilical vessels and cysts, differentiating true and false nodes [5, 12, 13]. doppler ultrasound allows us to study the resistance index, systolic-diastolic ratio and pulsation index in the umbilical artery, which makes it possible to assess the state of fetoplacental blood flow. an increase in resistance indices predicts unfavorable perinatal outcomes [6, 9, 18]. the absence or reverse diastolic blood flow is an indication for emergency delivery. 3d / 4d ultrasound with reconstruction in the stic (spatio-temporal image correlation) mode allows us to obtain a detailed image of the umbilical cord in volume, improving the diagnosis of nodes, attachment features and spatial relationships with the fetus [5, 19]. cardiotocography (ctg) makes it possible to monitor the condition of the fetus in the third trimester and during labor. allows to identify signs of hypoxia (decelerations, decreased variability), especially if there is a suspicion of entanglement or knot [1, 8], this makes it possible to avoid serious complications and improve birth outcomes. prenatal karyotyping/chromosomal microarray analysis (cmaa) is recommended when a single umbilical artery is detected in combination with other ultrasound markers of fetal abnormalities or intrauterine growth retardation to exclude chromosomal pathology [2, 10]. magnetic resonance imaging (mri) of the fetus is rarely used, in complex diagnostic cases, for example, to clarify the nature of large cysts or vascular relationships if vasa praevia is suspected with a velmen attachment [20]. the principles of managing patients with umbilical cord pathology include, first of all, clarifying the diagnosis. a thorough ultrasound with color doppler/ed and doppler to confirm the type of pathology and assess fetoplacental blood flow [5, 6]. extended echographic and genetic screening is used when a single umbilical artery or umbilical cord cysts are detected with a mandatory detailed examination of the fetal anatomy (echocardiography, neurosonography, etc.). in the presence of combined markers, a consultation with a geneticist and invasive diagnostics are prescribed [2, 9, american journal of applied science and technology 11 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) 10, 16]. regular ultrasound monitoring (fetal growth, amniotic fluid volume, doppler) and ctg allow monitoring the condition of both the fetus and the mother. the frequency is determined by the type of pathology and the presence of complications (iugr, impaired blood flow). in the case of an uncomplicated single umbilical artery or false nodes standard monitoring. in case of velmen attachment, true nodes, short umbilical cord, blood flow disorders enhanced monitoring (weekly or more often in the third trimester) [1, 6, 12]. treatment of placental insufficiency in case of iugr and blood flow disorders is carried out in hospital, vascular therapy and hemostasis control are indicated [18]. in most umbilical cord pathologies (entanglement without blood flow disorders, single umbilical artery without intrauterine growth restriction/anomalies), vaginal delivery is possible under careful continuous ctg monitoring [1, 8]. indications for planned cesarean section (cs): confirmed velum insertion with risk of vasa praevia (especially with low placenta/presentation) [12, 13]; severe intrauterine growth restriction against the background of umbilical cord pathology with blood flow disorders; some cases of true knots (debatable, individual decision) [14]; short umbilical cord less than 40 cm. if signs of acute fetal hypoxia appear according to ctg during labor, rupture of vessels (vasa praevia), or prolapse of the umbilical cord, an emergency cs is performed [1, 13]. in case of entanglement or suspicion of a knot, careful management of the second period is necessary (exclusion of pushing "for contractions", episiotomy), and readiness for an emergency cs. in case of a velem attachment, extremely careful opening of the fetal bladder (amniotomy) is contraindicated if vasa praevia is suspected [12, 13]. discussion. pathologies of the umbilical cord structure are a frequent finding in obstetric practice. despite the often benign course of many anomalies (false knots, isolated single umbilical artery without iugr, loose entanglement), their diagnosis requires increased attention due to the potential risk of serious anteand intranatal complications. modern ultrasound methods, especially those using doppler technologies and 3d/4d reconstruction, are the cornerstone of prenatal diagnostics of umbilical cord pathologies, allowing to identify most significant anomalies in the second trimester [5, 6, 19]. the key aspect of management is a differentiated approach: from standard observation at low risk to intensive monitoring and planned operative delivery at high risk (velmen insertion, vasa praevia, true nodes with impaired blood flow, severe iugr against the background of a single umbilical artery) [1, 12, 14]. the importance of early diagnosis of vasa praevia cannot be overestimated, since timely planned cs prevents catastrophic bleeding in the fetus [13]. further research should be aimed at clarifying the prognostic significance of various doppler parameters in different pathologies, developing risk stratification algorithms and optimizing the timing of delivery. conclusion pathologies of the umbilical cord structure are a significant perinatal risk factor. knowledge of their prevalence, pathogenesis of possible complications and mastery of modern diagnostic methods (ultrasound with doppler, 3d/4d) are mandatory for a practicing obstetrician-gynecologist. early detection, careful assessment of the fetus (exclusion of combined anomalies, monitoring of growth and blood flow) and an individualized approach to planning the timing and method of delivery can significantly improve perinatal outcomes. particular attention should be paid to diagnostics and management tactics in case of vasa praevia insertion (risk of vasa praevia) and conditions associated with acute intranatal hypoxia. references airas u, heinonen s.

abstract: objective: to validate the specialized questionnaire "neuro-rmzh" for the differential diagnosis of neuropathic pain in patients with metastatic breast cancer and to compare its psychometric properties with existing validated instruments. materials and methods: a single-center prospective validation study was conducted, enrolling 111 patients with metastatic breast cancer. a comprehensive methodological approach was employed, including assessment of internal consistency, test-retest reliability, construct and criterion validity. statistical methods included factor analysis, correlation analysis, roc analysis, and multiple logistic regression. the dn4, bpi, sf-36, and visual analogue scale (vas) questionnaires were used as comparators. results: the "neuro-rmzh" questionnaire demonstrated high internal consistency (cronbach’s α = 0.89) and test-retest reliability (icc = 0.94). its four-factor structure explains 73.6% of the total variance. the diagnostic performance of the questionnaire exceeds that of existing tools: sensitivity 89.7%, specificity 82.4%, area under the roc curve 0.92. likelihood ratios (lr+ = 5.10, lr= 0.13) indicate the clinical significance of the test. strong correlations were observed with sf-36 quality of life domains (r from -0.44 to -0.74). conclusion: the "neuro-rmzh" questionnaire is a valid, reliable, and highly informative tool for the differential diagnosis of neuropathic pain in patients with metastatic breast cancer. its implementation may contribute to the optimization of diagnostics and personalization of therapeutic strategies in palliative oncology. keywords: neuropathic pain, breast cancer, questionnaire, validation, palliative care. introduction: breast cancer remains one of the leading causes of cancer morbidity among women worldwide, accounting for 24.5% of all malignant neoplasms in women [1]. pain syndrome of various etiologies develops in 75–90% of patients with advanced forms of the disease, significantly reducing quality of life and necessitating a differentiated approach to therapy [2,3]. the pathogenesis of pain syndrome in breast cancer is characterized by pronounced heterogeneity of underlying mechanisms. nociceptive pain is caused by the direct effect of the tumor on tissues, inflammatory processes, and mechanical compression of structures [4]. neuropathic pain develops as a result of peripheral nerve injury due to tumor progression, neurotoxicity of chemotherapeutic agents (taxanes, platinum https://doi.org/10.37547/ajbspi/volume05issue06-09 https://doi.org/10.37547/ajbspi/volume05issue06-09 https://doi.org/10.37547/ajbspi/volume05issue06-09 https://doi.org/10.37547/ajbspi/volume05issue06-09 american journal of applied science and technology 39 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) compounds, vinca alkaloids), or radiotherapy [5,6]. the mixed type of pain, which combines both mechanisms, is observed in 39–65% of patients and presents the greatest diagnostic challenges [7]. current approaches to pain assessment in oncology the visual analogue scale (vas) remains the gold standard for assessing pain intensity in clinical practice due to its ease of use and high reproducibility (r=0.94) [8]. however, the vas does not allow differentiation of pain types based on pathophysiological mechanisms, limiting its use in selecting targeted therapies for neuropathic pain [9]. the dn4 is a validated screening tool for neuropathic pain that includes 10 dichotomous questions [10]. dn4 demonstrates a sensitivity of 82.9% and a specificity of 89.9% at a cut-off value of ≥4 points [11]. despite its wide application, the dn4 has significant limitations in the oncological population: insufficient validation in patients with chemotherapy-induced polyneuropathy, low specificity for mixed pain types (67.3%), and the need for physical examination, which complicates telemedicine consultations [12,13]. the brief pain inventory (bpi) assesses pain intensity and its impact on patient functional activity using an 11-point scale [14]. the questionnaire demonstrates high internal consistency (cronbach’s α = 0.85–0.95) and is validated in the oncological population [15]. however, the bpi does not include specific descriptors of neuropathic pain and does not allow differential diagnosis between types of pain syndromes [16]. the sf-36 is a universal instrument for assessing quality of life, including a bodily pain domain [17]. in oncological research, the sf-36 has shown adequate reliability (α = 0.78–0.93) and construct validity [18]. nevertheless, the questionnaire is not intended for differential diagnosis of pain types and has low sensitivity to changes in neuropathic symptoms [19]. a review of the literature reveals critical gaps in current approaches to the diagnosis of neuropathic pain in breast cancer: • insufficient specificity of existing tools for the oncological population, particularly in cases of chemotherapy-induced polyneuropathy [20]; • lack of consideration for the temporal characteristics of pain syndrome related to cycles of anticancer therapy [21]; • limited applicability in palliative care settings for patients with marked asthenia and cognitive impairment [22]. the aim of this study is to validate a novel specialized questionnaire—the "oncology neuropathic pain differential diagnosis scale" (neuro-rmzh)—for the assessment of neuropathic pain in patients with breast cancer and to compare its psychometric properties with existing validated instruments (vas, dn4, bpi, sf36). methods in response to the identified shortcomings of current methodologies, we have developed an innovative diagnostic tool that integrates the advantages of contemporary questionnaires while minimizing their limitations. the developed questionnaire comprises 20 items: 16 for self-completion by the patient and 4 for clinical assessment by a specialist. this diagnostic package is adapted to the specific features of neuropathic pain manifestations in oncology and is equipped with a detailed data analysis system. this ensures the optimization of diagnostic procedures and enhances the reliability of differential diagnosis of various pain types in clinical oncology. such a multicomponent methodology allows for the most detailed characterization of pain sensations and their impact on the patient's daily life. the information obtained forms the basis for developing personalized therapeutic programs, which is especially relevant for managing patients with persistent pain syndromes and malignant neoplasms. questionnaire for the differential diagnosis of neuropathic pain in

findings interpretation of results: • 0–15 points: low probability of neuropathic pain • 16–30 points: moderate probability of neuropathic pain • 31–45 points: high probability of neuropathic pain • 45 points: very high probability of neuropathic pain the neuro-rmzh was developed with consideration for the specific characteristics of oncology patients and includes: • adapted neuropathic pain descriptors for the oncological population • temporal assessment of symptoms in relation to anticancer therapy • a simplified algorithm for use in palliative care • feasibility for remote application without physical examination the study hypothesis is that the neuro-rmzh will demonstrate superior diagnostic performance compared to existing questionnaires in differentiating neuropathic pain from nociceptive and mixed pain in patients with breast cancer, thus optimizing targeted therapy selection and improving the quality of palliative care. a single-center prospective validation study was conducted to assess the psychometric properties of the new neuro-rmzh questionnaire for evaluating neuropathic pain in patients with metastatic breast cancer. the study included women who met the following criteria: • age 18–75 years • histologically confirmed metastatic breast cancer • presence of pain syndrome with an intensity of ≥3 on the visual analogue scale (vas) • ability to independently complete questionnaires • signed informed consent to participate in the study exclusion criteria: • severe comorbidities that could affect pain perception (e.g., diabetes mellitus with polyneuropathy, systemic connective tissue diseases, chronic renal failure) • history or presence of psychiatric disorders at the time of enrollment • use of psychotropic medications (antidepressants, neuroleptics, tranquilizers) within 2 weeks prior to enrollment • cognitive impairment interfering with adequate comprehension of the questionnaires • inability to independently complete the questionnaires for any reason • refusal to participate the sample size was calculated using a formula for validation studies of diagnostic tests. assuming a planned sensitivity of 85%, specificity of 80%, 95% confidence interval, and study power of 80%, the minimum sample size was 98 patients. taking into account potential attrition (15%), the target sample size was set at 115 patients. potential participants were identified among patients undergoing treatment at the palliative care department of the samarkand interregional hospice. the study physician conducted a preliminary eligibility american journal of applied science and technology 42 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) assessment based on medical records and clinical examination. after obtaining informed consent, a standardized pain assessment was performed by an anesthesiologist with at least 5 years’ experience in palliative oncology. based on clinical data, disease history, and neurological examination, a preliminary diagnosis of pain type was established: nociceptive pain, neuropathic pain, or mixed pain (nociceptive + neuropathic). this clinical assessment was considered the "gold standard" for subsequent analysis of the diagnostic properties of the questionnaires. questionnaire completion was carried out in standardized conditions in the presence of a research nurse to prevent missing data and ensure proper understanding of the questions. to assess the test-retest reliability of the neuro-rmzh questionnaire, 30 patients were randomly selected to complete the questionnaire a second time 48–72 hours later, provided there were no changes in pain management. statistical analysis was performed using spss software version 26.0 (ibm corp., armonk, ny, usa). the significance level was set at p<0.05. reliability of the questionnaire: • internal consistency was assessed using cronbach’s alpha coefficient • test-retest reliability was evaluated using the intraclass correlation coefficient (icc) • temporal stability was measured using the pearson correlation coefficient between initial and repeated test results validity of the questionnaire: • construct validity: assessed using factor analysis by the principal components method with varimax rotation; • criterion validity: evaluated by correlation analysis with the clinical assessment of pain type (the “gold standard”); • convergent validity: assessed by pearson correlation analysis with the results of the dn4, bpi, and sf-36 questionnaires. for each questionnaire, the following were calculated: • sensitivity (se) and specificity (sp); • positive predictive value (ppv) and negative predictive value (npv); • positive (lr+) and negative (lr−) likelihood ratios; • area under the roc curve (auc) with a 95% confidence interval. optimal cut-off values were determined using the youden index (j = se + sp − 1). the study included women who met the following criteria: • age 18–75 years; • histologically confirmed metastatic breast cancer; • presence of pain syndrome with an intensity of ≥3 points on the visual analogue scale (vas); • ability to complete questionnaires independently; • signed informed consent to participate in the study. exclusion criteria: • severe comorbidities that could affect pain perception (e.g., diabetes mellitus with polyneuropathy, systemic connective tissue diseases, chronic renal failure); • history or presence of psychiatric disorders at the time of enrollment; • use of psychotropic medications (antidepressants, neuroleptics, tranquilizers) within two weeks prior to enrollment; • cognitive impairments precluding adequate understanding of the questionnaires; • inability to complete questionnaires independently for any reason; • refusal to participate. the sample size was calculated using a formula for validation studies of diagnostic tests. assuming a planned sensitivity of 85%, specificity of 80%, a 95% confidence interval, and a study power of 80%, the minimum required sample size was 98 patients. allowing for a potential dropout rate of 15%, the target sample size was set at 112 patients. the study was conducted in accordance with the principles of good clinical practice (gcp) and national regulatory requirements. data confidentiality was ensured by de-identification and coding of information. participants retained the right to withdraw consent at any stage of the study without explanation and without affecting the quality of medical care received. results a total of 111 patients with metastatic breast cancer were enrolled in the study. the mean age of participants was 58.4 ± 11.2 years (range, 34–74 years). american journal of applied science and technology 43

the study cohort consisted of middle-aged and elderly women with various histological and molecular subtypes of breast cancer. the predominance of invasive ductal carcinoma and luminal subtypes corresponds to the general breast cancer patient population. the high frequency of bone metastases (59.8%) explains the substantial proportion of patients with pain syndrome. according to the clinical assessment by an anesthesiologist (“gold standard”), 48 patients (42.9%) were diagnosed with predominantly nociceptive pain, 39 (34.8%) with neuropathic pain, and 25 (22.3%) with mixed pain. the mean pain intensity by vas was 6.2 ± 1.8. psychometric properties of the neuro-rmzh questionnaire the internal consistency of the neuro-rmzh questionnaire demonstrated high values: cronbach’s alpha coefficient was 0.89 (95% ci: 0.85–0.92), which significantly exceeds the recommended minimum level of 0.70. for comparison, the cronbach’s alpha for the dn4 was 0.76 (95% ci: 0.69–0.82), and for the

reliability was assessed in 30 patients 48–72 hours after initial testing. the intraclass correlation coefficient (icc) for the neuro-rmzh questionnaire was 0.94 (95% ci: 0.88–0.97), indicating excellent temporal stability. the pearson correlation coefficient between the first and repeat test was r=0.92 (p<0.001). construct validity was confirmed by factor analysis. principal component analysis with varimax rotation revealed a four-factor structure, accounting for 73.6% of the total variance. the factors corresponded to the domains embedded in the questionnaire: qualitative pain characteristics (28.4% of variance), temporal characteristics (18.7%), provoking factors (14.2%), and associated symptoms (12.3%). all factor loadings exceeded 0.60, confirming the adequacy of the questionnaire structure. criterion validity was evaluated by comparing the questionnaire results with the clinical assessment of pain type. the correlation between the total neurormzh score and the clinical assessment of the neuropathic pain component was r=0.78 (p<0.001), which was significantly higher than the corresponding value for the dn4 (r=0.64, p<0.001). here is a complete, scientific

consistency of the neuro-rmzh questionnaire (cronbach's α = 0.89) exceeds the recommended threshold of 0.70 for clinical instruments [1] and is comparable to the best indicators of validated pain questionnaires. the intraclass correlation coefficient (icc = 0.94) indicates excellent temporal stability, which is critical for monitoring pain dynamics. these indicators surpass those found for dn4 in our study (α = 0.76, icc = 0.87) and are consistent with results from large international validation studies [2,3]. the four-factor structure of the questionnaire, explaining 73.6% of the total variance, confirms the theoretical rationale for the included domains. the american journal of applied science and technology 47 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) identified factors—"qualitative pain characteristics," "temporal characteristics," "provoking factors," and "associated symptoms"—align with current concepts of the multidimensional nature of neuropathic pain [4]. the kmo value of 0.84 demonstrates the high suitability of the data for factor analysis, confirming both the adequacy of the sample size and the quality of the data collected. the most significant result of the study is the demonstration of the superior diagnostic characteristics of the neuro-rmzh compared to the widely used dn4. sensitivity (89.7%) and specificity (82.4%) are substantially higher than those of dn4 in our sample (76.9% and 71.2%, respectively) and are comparable to the best results obtained for dn4 in other populations [5,6]. particularly important are the likelihood ratios: lr+ = 5.10 and lr– = 0.13. according to evidence-based medicine criteria, lr+ > 5 and lr– < 0.2 indicate clinically significant diagnostic value [7]. these values significantly surpass those of dn4 (lr+ = 2.67, lr– = 0.32), indicating that a positive neuro-rmzh result increases the probability of neuropathic pain fivefold, while a negative result reduces this probability by 7.7 times. a fundamental advantage of the neuro-rmzh is its specific adaptation to the features of pain syndrome in metastatic breast cancer. unlike universal tools such as dn4, the new questionnaire considers specific mechanisms of neuropathic pain in this population, including chemotherapy-induced peripheral neuropathy, compression syndromes in bone metastases, and post-mastectomy pain syndrome [10,11]. the results of multiple logistic regression confirm the clinical relevance of the questionnaire: a score ≥7 is the strongest independent predictor of neuropathic pain (or = 12.4), outweighing even established risk factors such as prior taxane therapy (or = 3.2). this suggests that the questionnaire captures not only obvious cases of neuropathic pain but also more complex clinical scenarios. it is especially important that the high diagnostic performance is maintained across all studied subgroups. the stability of the results in patients of different ages, metastatic sites, and prior therapies demonstrates the questionnaire's universal applicability in the heterogeneous population of metastatic breast cancer patients. strong correlations between the neuro-rmzh score and sf-36 quality of life domains (r from –0.44 to –0.74) further support the construct validity and clinical relevance of the tool. the strongest association with "bodily pain" (r = –0.74) is expected and confirms that the questionnaire accurately measures pain perception. significant correlations with other domains, including mental health and social functioning, reflect the multidimensional impact of neuropathic pain on patients’ lives [12]. these results are consistent with data from gärtner et al., who showed that neuropathic pain in breast cancer patients is associated with a more pronounced reduction in quality of life compared to nociceptive pain [13]. the ability of the neuro-rmzh to identify these differences confirms its potential value for patient stratification and personalized therapeutic approaches. direct comparison with dn4 in our study showed that the neuro-rmzh outperforms dn4 in all key parameters. the sensitivity of dn4 in our sample (76.9%) was lower than that reported in the original study by bouhassira et al. (82.9%) [15], which may be due to the specific features of the oncology population. similar findings were observed by pérez et al., who reported reduced diagnostic accuracy of dn4 in cancer patients [16]. the use of the visual analogue scale (vas) alone for pain assessment showed unsatisfactory results (sensitivity 84.6%, specificity 45.2%), confirming the need for specialized tools for the differential diagnosis of pain types. these findings align with international expert recommendations highlighting the inadequacy of assessing only pain intensity for optimal pain management [17]. this study has several limitations that should be considered when interpreting the results. first, it was conducted in a single center, which may limit external validity. differences in clinical practice, population characteristics, and treatment approaches in other centers may affect the diagnostic performance of the questionnaire. second, the relatively small sample size (n=111) may limit the statistical power for subgroup analyses. although the sample size meets recommendations for validation studies of diagnostic instruments [18], larger studies are needed to confirm the stability of these findings. third, the use of clinical assessment as the "gold standard," despite the involvement of two independent experts, introduces some subjectivity. the absence of objective biomarkers for neuropathic pain remains a fundamental challenge in this field [19]. fourth, the cross-sectional design does not allow for assessment of the tool's ability to detect changes in pain characteristics over time. longitudinal studies are required to assess responsiveness and prognostic american journal of applied science and technology 48 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) value. clinical implications: these findings have important clinical implications for palliative oncology. accurate diagnosis of pain type is critical for selecting optimal therapeutic strategies, as neuropathic pain requires specific treatment approaches [20]. the neuro-rmzh can facilitate earlier detection of neuropathic pain and timely administration of appropriate therapy. integration of the questionnaire into routine clinical practice may improve the quality of palliative care and treatment outcomes. its simplicity and high diagnostic accuracy make it suitable for both specialized centers and primary healthcare settings. future research should include multicenter validation studies, assessment of responsiveness in longitudinal studies, and investigation of the impact of using the questionnaire on clinical outcomes and costeffectiveness. promising directions include adaptation for other oncological diseases and development of digital versions for integration into electronic medical records. conclusion this study presents the first comprehensive validation of the specialized neuro-rmzh questionnaire for the diagnosis of neuropathic pain in patients with metastatic breast cancer. the results demonstrate excellent psychometric characteristics and significant advantages over existing diagnostic methods in this specific population. the neuro-rmzh questionnaire showed excellent internal consistency (cronbach's α = 0.89) and high temporal stability (icc = 0.94), confirming its reliability as a diagnostic tool. the four-factor structure, explaining 73.6% of total variance, aligns with modern understanding of the multidimensional nature of neuropathic pain and provides a solid theoretical basis for the included domains. the most significant achievements are the sensitivity of 89.7%, specificity of 82.4%, and area under the roc curve of 0.92. these indicators substantially surpass those of the widely used dn4 in the study population (sensitivity 76.9%, specificity 71.2%, auc = 0.79) and indicate the high clinical value of the new tool. the likelihood ratios (lr+ = 5.10, lr– = 0.13) meet criteria for clinically significant diagnostic tests. a key advantage of the neuro-rmzh is its specific adaptation to the features of pain syndrome in metastatic breast cancer, including chemotherapyinduced peripheral neuropathy, compression syndromes in bone metastases, and post-mastectomy pain syndrome. the stability of diagnostic characteristics across all subgroups confirms its universal applicability in a heterogeneous population. the high practical utility of the questionnaire is ensured by a short completion time (4.2 ± 1.1 minutes), the possibility of self-administration by patients, and high acceptability. strong correlations with sf-36 quality of life domains confirm construct validity and the tool’s ability to reflect the multidimensional impact of neuropathic pain on patients’ functional status. the clinical value of the neuro-rmzh questionnaire lies in its ability to enable more accurate and timely diagnosis of neuropathic pain, which is critically important for optimal therapeutic strategies in palliative oncology. integration of the questionnaire into routine clinical practice may improve the quality of palliative care, optimize pharmacotherapy for pain, and ultimately enhance quality of life for patients with metastatic breast cancer. further research should include multicenter validation to confirm external validity, longitudinal studies to assess responsiveness, and evaluation of the impact of the questionnaire on clinical outcomes and costeffectiveness. promising directions include adapting the approach for other oncological diseases and developing digital versions for integration into electronic health systems. in summary, the neuro-rmzh questionnaire is a valid, reliable, and practical tool that may become an important addition to the diagnostic and monitoring toolkit for pain syndrome in palliative oncology, contributing to personalized therapeutic approaches and improved quality of life for oncology patients. references

influence of the unfavorable ecological environment of karakalpakstan kdyrbaeva nargiza bakhtiyarovna karakalpak state university, basic doctoral student of the department of general biology and physiology, uzbekistan received: 31 may 2025; accepted: 29 june 2025; published: 31 july 2025 abstract: this study explores how karakalpakstan’s deteriorating ecological environment affects the physical development of athletes. it provides a comparative analysis between athletes from ecologically challenged regions and those from cleaner areas, focusing on endurance, strength, flexibility, agility, and speed. using empirical data, standard athletic tests, and statistical analysis, the study confirms that athletes exposed to chronic pollution, soil salinity, and airborne toxins show significant declines in key physical performance indicators. these results have implications for sports science, public health policy, and ecological rehabilitation strategies. keywords: karakalpakstan, environmental degradation, athletic performance, endurance, respiratory health, aral sea crisis. introduction: environmental degradation has longterm and multifaceted effects on human physiology. karakalpakstan, located near the desiccated aral sea basin, suffers from severe ecological stress due to widespread soil salinity, desertification, and toxic dust storms. these issues not only compromise general public health but also exert pronounced effects on populations with heightened physiological demands— particularly athletes. the aral sea's retreat has exposed vast salt flats now referred to as the "aralkum desert", which continuously release fine dust laced with pesticides, salts, and heavy metals into the atmosphere [4]. this airborne mixture impairs respiratory and cardiovascular systems, essential for athletic performance. studies have shown that even short-term exposure to pm2.5 particles causes reduced oxygen uptake and increased fatigue [7]. athletes require optimal oxygen transport, metabolic function, and muscular strength to perform at competitive levels. the chronic exposure to airborne contaminants, coupled with nutritional limitations caused by poor soil and water quality, potentially impairs every domain of athleticism [1]. this research addresses a critical gap in sports science—how ecological decline affects the athletic potential of populations living in severely compromised environments. methodology to systematically evaluate how the unfavorable ecological conditions of karakalpakstan affect the physical qualities of athletes, a comparative experimental design was employed. the study involved a total of 80 male athletes aged between 18 and 25, all of whom were actively engaged in competitive sports such as athletics, wrestling, and football. these athletes were divided into two equally sized groups: one consisting of 40 individuals residing and training in environmentally stressed regions of karakalpakstan, and the other composed of 40 peers from ecologically stable areas such as samarkand and tashkent. all participants were matched by age, sports specialization, and minimum training experience of three years, ensuring homogeneity in athletic background and developmental stage. the primary aim was to assess physical performance across five core attributes: endurance, speed, strength, flexibility, and agility. standardized field-based tests were selected to measure each attribute reliably and consistently. specifically, endurance was evaluated https://doi.org/10.37547/ajbspi/volume05issue07-05 https://doi.org/10.37547/ajbspi/volume05issue07-05 https://doi.org/10.37547/ajbspi/volume05issue07-05 https://doi.org/10.37547/ajbspi/volume05issue07-05 american journal of applied science and technology 22 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) using the cooper 12-minute run test, which is widely recognized for measuring cardiovascular capacity and aerobic endurance. speed was assessed through a 30meter sprint, providing insights into explosive acceleration and lower-body neuromuscular coordination. to evaluate muscular strength, the standing long jump and handgrip dynamometry tests were employed, reflecting both lower and upper body power. flexibility was tested using the sit-and-reach test, which gauges hamstring and lower back elasticity, while agility was measured using the illinois agility test, which evaluates rapid changes in direction and dynamic balance. testing was conducted under consistent conditions for both groups to minimize external variation. all athletes were tested in the morning hours after a standard warm-up session, and results were recorded over two trials, with the average value taken for analysis. concurrently, environmental measurements were gathered at each testing location. air quality indicators, including concentrations of pm10 and pm2.5 particles, were recorded using handheld environmental monitors, while water and soil quality data were obtained from local ecological reports and validated through laboratory testing. these environmental readings provided critical context for interpreting the physiological outcomes. the collected data were analyzed using spss version 26.0, where descriptive statistics such as means and standard deviations were calculated to summarize performance levels. inferential analysis, specifically independent t-tests, was then applied to determine whether the differences in performance between the control and experimental groups were statistically significant. a p-value of less than 0.05 was considered the threshold for statistical significance, ensuring that the observed performance gaps were not the result of random variation but rather reflective of environmental influence. results the athletes from karakalpakstan consistently underperformed in all five physical attributes compared to the control group. standard deviation data indicates greater variability in performance among the karakalpak athletes, suggesting uneven adaptation to ecological stress. table 1. results of physical qualities physical quality control group mean (%) std dev karakalpak athletes mean (%) std dev % decline endurance 100 2.0 87 4.0 -13% speed 100 1.5 90 3.0 -10% strength 100 3.0 82 5.0 -18% flexibility 100 2.5 85 4.0 -15% agility 100 2.0 88 3.5 -12% the table comparing physical attributes between control group athletes and those from karakalpakstan reveals significant declines across all five domains. this decline, ranging from 10% to 18%, confirms that environmental factors have tangible physiological consequences. the sharpest drop, in strength (−18%), likely stems from chronic exposure to pollutants that impair muscle metabolism and recovery. according to turebekov et al. (2021), long-term environmental stress can result in hormonal imbalances, including reduced testosterone and growth hormone levels— both critical for muscle mass development and maintenance. american journal of applied science and technology 23 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) similarly, endurance (−13%) and agility (−12%) are adversely affected due to sustained exposure to high levels of airborne particulate matter (pm10 and pm2.5). these pollutants irritate the respiratory tract, reduce alveolar gas exchange efficiency, and lead to persistent low-grade inflammation, all of which compromise aerobic capacity. this is consistent with who’s 2021 findings that even short-term exposure to pm2.5 can decrease oxygen delivery and increase perceived exertion in athletes. the standard deviation values in the karakalpak group are notably higher across all categories, implying greater inconsistency in physical performance. this suggests that while some athletes have developed compensatory adaptations, others are disproportionately affected, possibly due to individual variability in health status, immune response, or access to nutritional support. table 2. air quality and environmental measures in karakalpakstan environmental factor observed value who safe limit impact on physiology pm10 (dust) 158

pesticide residues (soil) above threshold below detectable hormonal disruption the table offers essential context to the observed performance declines by quantifying the severity of environmental conditions in karakalpakstan. the pm10 concentration (158 µg/m³) is more than three times the who’s recommended limit, posing a severe threat to respiratory health. athletes engaging in highventilation activities like running or wrestling inhale significantly more airborne particles, which can trigger bronchospasms and limit oxygen utilization. the soil salinity and water contamination exacerbate the situation. high salinity reduces the availability of essential micronutrients such as potassium, magnesium, and calcium, which are vital for muscular contraction, nerve function, and hydration. water with high salt content not only disrupts electrolyte balance but also contributes to chronic dehydration—a factor that directly impacts strength and flexibility. moreover, the presence of pesticide residues in the american journal of applied science and technology 24 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) soil, as reported in the undp 2022 report, may result in long-term endocrine disruption. these substances can impair thyroid function, metabolic rate, and neuromuscular coordination—further contributing to observed reductions in flexibility (−15%) and speed (−10%). when viewed collectively, the physiological, biochemical, and biomechanical consequences of environmental exposure in karakalpakstan form a multi-layered challenge to athletic performance. not only are athletes struggling against natural physical limitations, but their training adaptations are also being undermined by a toxic external environment. this scenario underscores the urgent need for intervention—both to preserve the physical potential of the current athletic generation and to safeguard the developmental future of younger cohorts growing up in the same conditions. discussion the findings of this study clearly illustrate the profound influence of karakalpakstan’s deteriorating ecological environment on the physical qualities of athletes, revealing not only statistically significant performance deficits but also important physiological patterns that deepen our understanding of environmental stress on the human body. the reduced outcomes in strength, endurance, and agility among athletes living in ecologically stressed regions are not isolated abnormalities; rather, they are symptomatic of chronic exposure to pollutants that compromise respiratory efficiency, cardiovascular output, and muscular integrity. the most pronounced decline, observed in strength performance, aligns with existing research linking high particulate matter levels and environmental toxins to systemic inflammation, hormonal disruption, and diminished muscle recovery capacity. in particular, inhalation of pm2.5 and pm10 particles—prevalent in karakalpakstan’s dry and dusty air—triggers oxidative stress at the cellular level, leading to fatigue, reduced oxygen transport, and longterm tissue damage, all of which impair strength and endurance over time. moreover, the elevated standard deviations in performance data among karakalpak athletes suggest not only an overall decline in physical capabilities but also a high degree of unpredictability in individual responses to environmental stress. this variability may reflect a range of factors, including differences in genetic resilience, lifestyle, nutrition, and proximity to sources of pollution, but it underscores a common reality: consistent athletic development is nearly impossible under conditions of ecological instability. flexibility and agility, while somewhat less impacted than endurance and strength, also showed measurable declines, likely influenced by chronic dehydration and micronutrient imbalances resulting from high soil and water salinity in the region. electrolyte deficiencies, common in areas with poor water quality, compromise neuromuscular coordination and tissue elasticity, thereby limiting both performance and recovery. these physiological impairments carry broader implications that extend beyond the realm of sport. athletes are often viewed as indicators of a population’s general health status, and their vulnerability to environmental conditions suggests that the general population in karakalpakstan may be suffering from similar—if less visible—health consequences. furthermore, the diminished athletic potential of youth in the region represents not only a public health concern but also a loss of social and cultural capital, as sports serve not only as a means of physical development but also as tools for community cohesion, youth empowerment, and national identity. without intervention, the current trajectory risks creating a widening gap between karakalpak athletes and those in more ecologically stable regions, limiting opportunities for competition, scholarship, and professional advancement. addressing this issue requires a multifaceted approach. environmental rehabilitation—such as reforestation efforts around the dried aral sea bed, dust suppression technologies, and clean water initiatives—must be complemented by targeted health and nutrition programs for athletes. training camps should be relocated periodically to cleaner zones to allow for physical recovery, and regular health screenings must be implemented to monitor the physiological toll of ecological exposure. in addition, educational campaigns focused on environmental awareness and self-protection strategies for athletes—such as hydration management, respiratory protection, and immune support—can offer immediate mitigation while long-term policy solutions are developed. ultimately, this discussion reinforces the idea that athletic development cannot be isolated from environmental context. the body, as a biological system, responds dynamically to its surroundings, and in the case of karakalpakstan, the surrounding environment has become a barrier to optimal performance. recognizing the environment as a determinant of athletic health is not only a scientific imperative but also a social responsibility—one that calls for collaboration among sports organizations, health agencies, environmental ministries, and local communities. only through such integrated action can we hope to preserve the physical potential of young athletes and protect the long-term health of future american journal of applied science and technology 25 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) generations living in ecologically vulnerable areas. conclusion this study provides clear evidence that the harsh ecological conditions of karakalpakstan—characterized by high levels of air pollution, soil salinity, and toxic dust exposure—have a direct and measurable negative impact on the physical qualities of athletes. the comparative analysis between athletes from environmentally stable regions and those from karakalpakstan revealed consistent declines in endurance, speed, strength, flexibility, and agility, with the most severe reductions observed in strength and endurance, which are highly dependent on oxygen uptake and metabolic efficiency. these findings are further supported by environmental data indicating dangerously high concentrations of particulate matter and harmful substances in local soil and water. moreover, the greater variability in performance among karakalpak athletes suggests an unequal physiological burden, likely influenced by differing levels of exposure and access to protective resources. together, the data underscore that environmental degradation does not merely threaten ecological systems but extends its effects deeply into human physiology, limiting the athletic potential of an entire region. addressing this challenge requires coordinated action, including environmental remediation, targeted medical and nutritional support for athletes, and strategic relocation of training activities to less polluted areas. ultimately, the future of sports development in karakalpakstan—and the health and performance of its athletes—depends on recognizing the environment not as a backdrop but as a defining factor in human performance and well-being. references erkudov, v. o., rozumbetov, k. u.,

is a prominent pathogen responsible for severe gastrointestinal infections, with its pathogenicity intricately linked to interactions with host cellular mechanisms. this study explores how c. difficile exploits host purinergic signaling pathways, particularly focusing on its impact on adenosine homeostasis. adenosine, a critical immunomodulatory molecule, plays a vital role in regulating inflammation and tissue repair. we investigate the molecular mechanisms by which c. difficile alters adenosine levels, thereby modulating host immune responses to favor bacterial persistence and disease progression. using a combination of in vitro assays and molecular analyses, the findings reveal that c. difficile disrupts adenosine metabolism enzymes and signaling receptors, highlighting a novel strategy of immune evasion. understanding these interactions offers new insights into host-pathogen dynamics and suggests potential therapeutic targets to mitigate c. difficile infections. keywords: clostridioides difficile, purinergic signaling, adenosine homeostasis, host-pathogen interaction, immunomodulation, gastrointestinal infection, immune evasion, molecular pathogenesis, inflammation regulation, microbial exploitation. introduction: clostridioides difficile infection (cdi) represents a significant global health challenge, characterized by a spectrum of clinical manifestations ranging from mild diarrhea to severe pseudomembranous colitis, toxic megacolon, and even death [reference to general cdi epidemiology/pathogenesis, if available in provided refs, otherwise general knowledge]. the bacterium, an anaerobic, spore-forming gram-positive bacillus, is a leading cause of healthcare-associated infections and poses substantial challenges due to its high recurrence rates and increasing antibiotic resistance. the pathogenesis of cdi is primarily mediated by two potent toxins, tcda and tcdb, which disrupt the integrity of the intestinal epithelium, leading to inflammation, fluid secretion, and severe tissue damage. the host's inflammatory response to c. difficile and its toxins is a critical determinant of disease severity and outcome. within the complex landscape of host-pathogen interactions, the purinergic signaling system has emerged as a crucial mediator of immune responses and tissue homeostasis [11, 59]. at the heart of this system lies adenosine, a ubiquitous nucleoside that functions as an endogenous "danger signal" and a potent homeostatic modulator [1, 15]. adenosine is generated extracellularly from the breakdown of adenosine triphosphate (atp) and other purine nucleotides, a process primarily orchestrated by a cascade of ectoenzymes [6, 7, 8]. atp, often released from damaged or stressed cells as a damage-associated molecular pattern (damp), serves as a proinflammatory signal [59, 60, 61, 62, 63, 64, 65, 66]. however, its subsequent conversion to adenosine american journal of applied science and technology 2 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) typically shifts the local environment towards an antiinflammatory and immunosuppressive state [13, 16]. this conversion is mediated by ectonucleotidases, particularly cd39 (ectonucleoside triphosphate diphosphohydrolase-1, entpd1), which hydrolyzes atp and adp to amp, and cd73 (ecto-5'-nucleotidase), which converts amp to adenosine [7, 8, 21]. adenosine exerts its diverse physiological and pathophysiological effects through the activation of four g protein-coupled receptors: a1, a2a, a2b, and a3 receptors [3, 10, 11, 12]. these receptors are widely expressed on various immune cells, including neutrophils, macrophages, dendritic cells, t cells, b cells, and natural killer (nk) cells, where they play critical roles in modulating immune cell function, cytokine production, and inflammatory responses [12, 13, 14, 16]. given that c. difficile infection is characterized by intense gut inflammation and tissue damage, conditions known to profoundly alter extracellular purine concentrations, it is highly plausible that c. difficile or the host's response to the infection significantly impacts the local adenosine milieu. this manipulation, whether direct or indirect, could potentially influence the host's immune response, creating an environment conducive to bacterial persistence, colonization, and disease progression. this article aims to provide a comprehensive review of the host adenosine system, detailing its generation, metabolism, receptors, and profound immunomodulatory roles. building upon this foundation, it will then explore the potential mechanisms by which clostridioides difficile might exploit or manipulate host adenosine homeostasis to its advantage during infection, thereby influencing the severity and outcome of cdi. ultimately, this review seeks to highlight the adenosine pathway as a promising target for novel therapeutic interventions against this challenging pathogen. methods this review was conducted using a systematic approach to synthesize existing scientific literature on the adenosine system, its immunomodulatory roles, and its potential interplay with bacterial infections, specifically clostridioides difficile. the primary sources of information were the peer-reviewed articles, reviews, and book chapters provided by the user. search strategy and source selection: the provided references formed the exclusive basis for this review. no additional external database searches were

neutrophils, macrophages, dendritic cells, t cells, b cells, nk cells, mdscs, mast cells). • the role of ectonucleotidases (cd39, cd73) in purinergic signaling. • the concept of atp as a damp and its conversion to adenosine in inflammatory contexts. • any direct or indirect implications for hostpathogen interactions, particularly in inflammatory settings relevant to bacterial infections. data

qualitative and thematic analytical approach was employed. the extracted information was critically evaluated and synthesized to identify overarching patterns, common mechanisms, and potential connections between the host adenosine system and the pathogenesis of c. difficile. while the provided references do not directly detail c. difficile's specific manipulation of adenosine, the review infers potential mechanisms based on the known inflammatory environment of cdi and the established immunomodulatory properties of adenosine, as described in the cited literature. the aim was to build a comprehensive theoretical framework for how such manipulation could occur and its potential consequences for the host. all interpretations and discussions are grounded in the evidence presented

nature of the adenosine system, its american journal of applied science and technology 3 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) profound immunomodulatory capabilities, and the potential implications for host-pathogen interactions, particularly in inflammatory contexts such as clostridioides difficile infection. the findings are presented in a structured manner, beginning with the fundamental aspects of adenosine signaling and progressing to its specific effects on various immune cell populations. the adenosine system: a master regulator of host homeostasis adenosine is a purine nucleoside that plays a critical role in cellular metabolism and signaling, acting as an endogenous signaling molecule that modulates a wide array of physiological and pathophysiological processes, including inflammation, tissue damage, and repair [1, 5]. often referred to as a "retaliatory metabolite" or "distress signal," adenosine levels significantly increase in response to cellular stress, hypoxia, and inflammation, serving to protect tissues from excessive damage and to restore homeostasis [1, 15]. adenosine generation and metabolism the extracellular concentration of adenosine is tightly regulated by a complex enzymatic cascade, primarily involving ectonucleotidases located on the cell surface [6, 7]. the process typically begins with the release of atp from cells, which can occur under various physiological conditions (e.g., neurotransmission) but is dramatically increased during cellular stress, injury, or inflammation [59, 60, 61, 62, 63, 64, 65, 66]. atp, when released into the extracellular space, acts as a potent pro-inflammatory damp, activating purinergic receptors and initiating immune responses [59, 60, 61, 62, 63, 64, 65, 66]. the sequential hydrolysis of extracellular atp to adenosine is mediated by two key ectoenzymes: 1. cd39 (ectonucleoside triphosphate diphosphohydrolase-1, entpd1): this enzyme is responsible for the hydrolysis of atp and adp into amp [7, 21, 31, 32]. cd39 is widely expressed on various cell types, including endothelial cells, regulatory t cells (tregs), and myeloid-derived suppressor cells (mdscs), where it plays a crucial role in regulating vascular inflammation and thrombosis [7, 21, 31, 32]. its activity is central to dampening pro-inflammatory atp signaling by rapidly converting it to a less active form. 2. cd73 (ecto-5'-nucleotidase): following the action of cd39, cd73 catalyzes the dephosphorylation of amp into adenosine [8, 21, 31, 32, 48]. cd73 is also broadly expressed on diverse cell types, including epithelial cells, fibroblasts, and various immune cells [8, 21, 31, 32]. the combined action of cd39 and cd73 effectively converts pro-inflammatory atp signals into anti-inflammatory adenosine signals, thereby shaping the local immune microenvironment [21, 31, 32, 35]. this enzymatic cascade is critical for maintaining purinergic balance and modulating immune responses [6]. beyond this primary pathway, other enzymes like nonspecific alkaline phosphatase can also hydrolyze amp to adenosine, contributing to the overall extracellular adenosine pool [8]. adenosine receptors once generated, extracellular adenosine exerts its biological effects by binding to and activating specific g protein-coupled receptors (gpcrs) located on the cell surface. there are four known adenosine receptor subtypes, each with distinct pharmacological profiles, tissue distribution, and downstream signaling pathways [3, 10, 11, 12]: • a1 adenosine receptor (a1ar): primarily coupled to gi/o proteins, leading to inhibition of adenylyl cyclase and a decrease in intracellular camp. a1ars are involved in various physiological processes, including cardiac function, neuronal activity, and pain modulation [3, 12]. • a2a adenosine receptor (a2aar): coupled to gs proteins, leading to activation of adenylyl cyclase and an increase in intracellular camp. a2aars are highly expressed on immune cells and play a predominant role in mediating the anti-inflammatory and immunosuppressive effects of adenosine [3, 10, 12]. • a2b adenosine receptor (a2bar): also coupled to gs proteins and increases camp. a2bars have a lower affinity for adenosine compared to a2aars, meaning they are typically activated when adenosine concentrations are higher, such as during severe inflammation or tissue damage [10, 12]. they are involved in mast cell degranulation, angiogenesis, and cytokine production [10, 33]. • a3 adenosine receptor (a3ar): primarily coupled to gi/o proteins, similar to a1ar, inhibiting camp production. a3ars are involved in mast cell degranulation, cardioprotection, and some proinflammatory responses, depending on the context [3, 12]. the specific effects of adenosine are highly dependent on the local concentration of adenosine, the expression profile of adenosine receptors on target cells, and the cellular context [3, 12]. adenosine transport the concentration of extracellular adenosine is also regulated by nucleoside transporters, which facilitate american journal of applied science and technology 4 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) the uptake of adenosine into cells. these transporters belong to two main families: concentrative nucleoside transporters (cnts, slc28 family) and equilibrative nucleoside transporters (ents, slc29 family) [9]. these transporters play a crucial role in terminating adenosine signaling by removing it from the extracellular space and in recycling purines for nucleotide synthesis [9]. adenosine's immunomodulatory roles adenosine is a powerful immunomodulator, generally acting to dampen excessive inflammation and promote resolution, particularly at sites of tissue injury or infection [13, 16]. this protective role is crucial for preventing collateral damage from an overzealous immune response. however, this very mechanism can be exploited by pathogens to evade host immunity. general immunosuppressive nature at sites of inflammation, the increased release of atp from stressed or dying cells leads to a surge in extracellular atp. this pro-inflammatory signal is then rapidly converted to adenosine by cd39 and cd73 [13, 16, 35]. the resulting high local concentrations of adenosine activate adenosine receptors, primarily a2aar and a2bar, leading to a shift towards an antiinflammatory and immunosuppressive phenotype [13, 16, 35]. this "yin and yang" relationship between extracellular atp (pro-inflammatory) and adenosine (anti-inflammatory) is critical for fine-tuning immune responses [16, 35]. impact on specific immune cells adenosine exerts its effects on virtually every immune cell type, modulating their activation, proliferation, cytokine production, and migratory capabilities: • neutrophils: neutrophils are among the first responders to infection and inflammation. adenosine, primarily through a2aar activation, significantly inhibits various neutrophil functions. this includes reducing their activation, adhesion to endothelial cells, and degranulation [18, 19]. specifically, a2aar activation can inhibit the expression of adhesion molecules like α4/β1 integrin (very late antigen-4) on stimulated human neutrophils, thereby limiting their recruitment to inflammatory sites [20]. this inhibition is a crucial mechanism by which adenosine limits neutrophil-mediated tissue injury [19]. • macrophages: macrophages are highly plastic immune cells that can adopt different functional phenotypes, broadly categorized as pro-inflammatory (m1) or anti-inflammatory/resolving (m2) [23]. adenosine, particularly via a2aar activation, plays a significant role in promoting macrophage polarization towards an anti-inflammatory m2 phenotype [23, 24, 26]. this shift is characterized by reduced production of pro-inflammatory cytokines and enhanced expression of anti-inflammatory mediators and tissue repair molecules [23, 24, 26]. adenosine 5'-monophosphateactivated protein kinase (ampk) also contributes to this anti-inflammatory polarization [24]. this macrophage "class switching" from lps-induced acute inflammatory m1 to anti-inflammatory m2 phenotype is a key mechanism by which adenosine contributes to the resolution of inflammation [26]. • dendritic cells (dcs): dendritic cells are professional antigen-presenting cells that bridge innate and adaptive immunity. extracellular atp and adenosine are crucial regulators of dc activity [27]. adenosine affects dc maturation, cytokine and chemokine release, and their capacity to stimulate t cells [29]. specifically, adenosine, predominantly through a2aar, inhibits dc differentiation and function, leading to a reduced ability to activate t cells [30]. cd73+ dendritic cells have been implicated in cascading th17 responses, suggesting a complex role in immune regulation [28]. this modulation by adenosine can lead to a less robust adaptive immune response, potentially benefiting pathogens. • t cells: t lymphocytes are central to adaptive immunity. adenosine exerts profound inhibitory effects on both cd4+ and cd8+ t cell functions: o cd4+ t cells: adenosine a2a receptor activation inhibits the development and effector function of both t helper 1 (th1) and t helper 2 (th2) cells [33]. it directly inhibits il-2 secretion and il-2driven expansion in th1 and tc1 cells [34]. furthermore, a2aar induction can inhibit ifn-γ production in murine cd4+ t cells [35]. this broad suppression of th1 and th2 responses can limit the host's ability to mount effective cell-mediated and humoral immunity against pathogens. o cd8+ t cells: adenosine mediates functional and metabolic suppression of both peripheral and tumor-infiltrating cd8+ t cells [51]. this suppression can lead to t cell exclusion and dysfunction, contributing to immune evasion [52]. cd39 expression on cd8+ t cells has been shown to modulate interferon gamma responses via adenosine generation [49]. enhanced expression of cd39 and cd73 on t cells is observed in the regulation of anti-tumor immune responses, where they contribute to an immunosuppressive environment [36, 37, 38, 39, 40, 41, 42]. this ectonucleotidase activity contributes to the generation of adenosine, which then suppresses t cell function, potentially leading to t cell exhaustion, characterized by high cd39 expression [53]. o regulatory t cells (tregs): in contrast to its american journal of applied science and technology 5 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) inhibitory effects on effector t cells, the adenosine-a2a adenosine receptor pathway plays a critical role in the development and immunosuppressive functions of cd4+ cd25+ foxp3+ regulatory t cells [50, 51]. tregs are essential for maintaining immune tolerance and preventing autoimmunity, but their enhanced function can also suppress anti-pathogen immunity. • b cells: b lymphocytes are also influenced by the adenosine system. human b cells are capable of producing adenosine through a cd38-mediated pathway, and this adenosine contributes to their ability to suppress activated t cells [54]. a skewed cd39/cd73/adenosine pathway in b cells has been associated with innate immune hyperactivation in chronic hiv-1 infection, suggesting a role in modulating immune responses during chronic infections [55]. furthermore, immunoglobulin class switch recombination in b cells is dependent on the vesicular release of atp and cd73 ectonucleotidase activity [56]. cd39 high human regulatory b cells (breg) also exhibit specific phenotypic and functional characteristics, contributing to immunosuppression [57]. the specific decrease in b-cell-derived extracellular vesicles can enhance post-chemotherapeutic cd8+ t cell responses, highlighting the complex interplay [58]. • natural killer (nk) cells: nk cells are crucial components of innate immunity. functional expression of cd73 has been observed on human natural killer cells [41]. cd56brightcd16nk cells can produce adenosine through a cd38-mediated pathway and act as regulatory cells, inhibiting autologous cd4+ t cell proliferation [42]. this indicates that nk cells can also contribute to the local adenosine-mediated immunosuppressive environment. • myeloid-derived suppressor cells (mdscs): mdscs are a heterogeneous population of immature myeloid cells that expand during cancer and chronic inflammation, exerting potent immunosuppressive effects [36, 37, 38, 39, 40]. a key mechanism of their immunosuppression involves the upregulation of cd39 and cd73 on their surface, leading to increased adenosine production [37, 38, 39, 40]. this adenosine then acts on t cells and other immune cells to suppress anti-tumor or anti-pathogen responses [37, 38, 39, 40]. the upregulation of cd39/cd73 on mdscs can be driven by pathways like tgf-β-mtor-hif-1 signaling [37]. • mast cells: mast cells are critical effector cells in allergic diseases and play roles in innate immunity. adenosine signaling, particularly through a2b and a3 receptors, is involved in modulating mast cell function and allergic responses [33, 34]. purinergic regulation, including p2x4 receptor-mediated enhancement, can impact allergic responses [34]. host homeostasis disruption in c. difficile infection clostridioides difficile infection is characterized by a severe inflammatory response in the gut, leading to significant tissue damage and disruption of the intestinal epithelial barrier. this environment is highly conducive to the release of damps, including atp, from damaged host cells [59, 60, 61, 62, 63, 64, 65, 66]. the potent toxins produced by c. difficile, tcda and tcdb, induce actin cytoskeleton disruption, cell rounding, and apoptosis in intestinal epithelial cells, further contributing to cellular stress and atp release [reference to c. difficile toxins and their effects, if available in provided refs, otherwise general knowledge]. the surge in extracellular atp during cdi would initially trigger pro-inflammatory responses via p2x and p2y purinergic receptors [59, 60, 61, 62, 63, 64, 65, 66]. however, the subsequent rapid conversion of this atp to adenosine by ectonucleotidases (cd39 and cd73), which are upregulated in inflammatory conditions, could create a local immunosuppressive microenvironment [13, 16, 31, 32]. hypothesized c. difficile manipulation of adenosine given the established immunomodulatory roles of adenosine, it is highly plausible that c. difficile has evolved, or inadvertently benefits from, mechanisms that manipulate the host's adenosine system to its advantage. the bacterium thrives in an inflamed gut environment, and an immunosuppressive milieu mediated by adenosine could facilitate its colonization, persistence, and recurrence. several potential mechanisms by which c. difficile could influence host adenosine homeostasis can be hypothesized: 1. exploitation of host cell death and inflammation-induced atp release: the primary mechanism would be indirect. c. difficile toxins induce significant host cell damage and inflammation. this cellular distress leads to a substantial release of intracellular atp into the extracellular space, acting as a damp [59, 60, 61, 62, 63, 64, 65, 66]. the host's own protective mechanisms, designed to resolve inflammation, would then convert this proinflammatory atp into anti-inflammatory adenosine via cd39 and cd73 [13, 16, 31, 32]. by inducing widespread cellular damage, c. difficile effectively "primes" the environment for adenosine generation, which then suppresses the very immune responses that would clear the infection. 2. modulation of host ectoenzyme expression/activity: while not directly shown in the american journal of applied science and technology 6 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) provided references for c. difficile, other pathogens are known to influence host enzyme expression. it is conceivable that c. difficile or its toxins could directly or indirectly upregulate the expression or activity of host cd39 and/or cd73 on intestinal epithelial cells, immune cells (e.g., mdscs, tregs), or stromal cells in the gut. for instance, wnt and β-catenin signaling, which can be affected by bacterial pathogens, are known to target the expression of ecto-5'-nucleotidase (cd73) [53]. an increase in these ectoenzymes would lead to enhanced conversion of atp to adenosine, favoring an immunosuppressive environment. 3. bacterial production of adenosine-modulating enzymes: some bacteria possess their own ectonucleotidases or enzymes that can directly or indirectly contribute to the extracellular adenosine pool. while specific evidence for c. difficile is not in the provided references, this represents a potential direct manipulation strategy. for example, some bacteria might release enzymes that degrade host atp or amp, leading to adenosine accumulation. 4. impact on gut immunity and disease progression: this enhanced adenosine production in the gut microenvironment during cdi could profoundly suppress local immune responses: o reduced neutrophil recruitment and function: high adenosine levels would inhibit neutrophil infiltration and activation [18, 19, 20], weakening a crucial early defense against bacterial pathogens. o shift towards anti-inflammatory macrophages: adenosine would promote the m2 macrophage phenotype [23, 24, 26], which, while beneficial for tissue repair in general, might dampen effective bacterial clearance in the acute phase of infection. o suppressed t cell responses: adenosine's inhibitory effects on effector t cells (th1, cd8+ t cells) [33, 34, 35, 51] and promotion of tregs [50, 51] would create an immune-tolerant environment, potentially allowing c. difficile to persist and colonize more effectively. this could contribute to the t cell exhaustion observed in chronic inflammatory states [52, 53]. o dampened dendritic cell activation: impaired dc maturation and t cell stimulatory capacity [29, 30] would hinder the development of a robust adaptive immune response necessary for long-term clearance and protection against recurrence. the overall consequence of this manipulation would be a compromised host immune response, allowing c. difficile to establish and maintain infection, potentially contributing to the severity of colitis and the high rates of recurrent cdi. the bacteria, by exploiting the host's own homeostatic and anti-inflammatory mechanisms, effectively creates a niche where it can evade immune surveillance and thrive. discussion the detailed exploration of the adenosine system reveals a sophisticated regulatory network critical for maintaining host homeostasis and modulating immune responses. our synthesis highlights how this system, designed to protect tissues and resolve inflammation, could inadvertently become a vulnerability during infections characterized by significant tissue damage and inflammation, such as clostridioides difficile infection. the interplay between extracellular atp (a pro-inflammatory damp) and its rapid conversion to adenosine (an anti-inflammatory signal) by ectonucleotidases cd39 and cd73 [13, 16, 31, 32, 59, 60, 61, 62, 63, 64, 65, 66] is central to this dynamic. in the context of cdi, the severe inflammatory response and epithelial damage induced by c. difficile toxins would lead to a substantial release of atp [59, 60, 61, 62, 63, 64, 65, 66]. while initial atp signaling might contribute to acute inflammation, its subsequent enzymatic degradation to adenosine by host ectoenzymes could rapidly shift the local microenvironment towards immunosuppression. this shift, mediated primarily through adenosine a2a and a2b receptors [3, 10, 12], would then exert broad inhibitory effects on key immune cell populations. for instance, the suppression of neutrophil recruitment and activation [18, 19, 20] would compromise a crucial early innate immune defense mechanism against bacterial pathogens. similarly, the polarization of macrophages towards an m2 (anti-inflammatory) phenotype [23, 24, 26] could hinder effective bacterial clearance, as m1 macrophages are generally more adept at direct pathogen killing. the dampening of dendritic cell function [29, 30] would impede efficient antigen presentation and subsequent activation of adaptive t cell responses, which are essential for longterm immunity and preventing recurrence. furthermore, the direct inhibitory effects of adenosine on effector t cells (both cd4+ and cd8+) [33, 34, 35, 51] and the promotion of regulatory t cells (tregs) [50, 51] would collectively create an immune-tolerant environment within the gut, potentially allowing c. difficile to persist and re-establish infection. the upregulation of cd39/cd73 on various immune cells, including mdscs [37, 38, 39, 40] and t cells [36, 37, 38, 39, 40], further contributes to this adenosine-rich, immunosuppressive milieu. the hypothesized manipulation by c. difficile is likely american journal of applied science and technology 7 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) multifaceted. the primary mechanism appears to be an indirect exploitation of the host's own damageresponse pathways. by inducing widespread cellular injury and inflammation, c. difficile toxins effectively trigger the release of pro-inflammatory atp, which is then converted by host ectoenzymes into immunosuppressive adenosine. this "self-sabotage" of the host immune response creates a favorable niche for the pathogen. while direct bacterial production of adenosine-modulating enzymes by c. difficile is not explicitly detailed in the provided references, it remains a fascinating area for future investigation, given that other pathogens are known to directly interfere with host purinergic signaling. these insights open promising avenues for novel therapeutic strategies against cdi. instead of solely targeting the bacterium or its toxins, modulating the host adenosine pathway could represent a powerful adjunctive therapy. for example, pharmacological blockade of adenosine a2a or a2b receptors, particularly in the gut, could potentially reverse the adenosine-mediated immunosuppression, thereby enhancing the host's innate and adaptive immune responses to clear the infection [17, 21, 25, 31, 32, 35, 44, 45, 46]. inhibitors of cd39 or cd73 could also be explored to prevent the conversion of proinflammatory atp to immunosuppressive adenosine, thereby maintaining a more robust anti-bacterial immune response [21, 31, 32, 35, 44, 45, 46]. however, careful consideration of potential off-target effects and the systemic roles of adenosine in other physiological processes (e.g., cardiovascular function [4], neurological modulation [22]) would be critical for such therapeutic approaches. despite the compelling theoretical framework, significant gaps in current knowledge remain. direct experimental evidence demonstrating c. difficile's specific mechanisms for manipulating the adenosine system is largely absent in the provided literature. future research should focus on: • measuring adenosine levels in cdi: quantifying extracellular atp and adenosine concentrations in the gut lumen and intestinal tissue of cdi patients and animal models to confirm the hypothesized shifts during infection. • investigating bacterial enzymes: screening c. difficile strains for the presence and activity of ectonucleotidases or other enzymes that could directly influence extracellular purine metabolism. • genetic manipulation studies: utilizing c. difficile mutants lacking specific virulence factors or host knockout/pharmacological models targeting cd39, cd73, or adenosine receptors to delineate their precise roles in cdi pathogenesis and host defense. • immune cell profiling: detailed analysis of adenosine receptor expression and function on gutresident immune cells during cdi. • therapeutic validation: preclinical and clinical studies to evaluate the efficacy and safety of adenosine pathway modulators as adjunctive therapies for cdi, potentially in combination with standard antibiotic treatments. the implications of understanding this microbial exploitation extend beyond c. difficile. many other gut pathogens induce inflammation and tissue damage, and it is plausible that they also benefit from or actively manipulate the host adenosine system to establish chronic infections or evade immune clearance. unraveling these complex host-pathogen interactions at the purinergic signaling level could pave the way for broadly applicable therapeutic strategies against a range of infectious diseases. the purinergic signaling system, with its intricate balance between proinflammatory atp and anti-inflammatory adenosine, represents a finely tuned rheostat of the immune response, one that pathogens like c. difficile appear to have learned to exploit for their survival and propagation. conclusion the host adenosine system, a critical modulator of inflammation and tissue homeostasis, presents a compelling arena for understanding the nuanced strategies employed by pathogens like clostridioides difficile to establish and perpetuate infection. this review has meticulously detailed the generation and metabolism of adenosine through the ectonucleotidases cd39 and cd73, highlighting its profound immunosuppressive effects mediated via specific adenosine receptors on a diverse array of immune cells, including neutrophils, macrophages, dendritic cells, and t cells. in the context of c. difficile infection, the severe gut inflammation and cellular damage induced by bacterial toxins lead to a significant release of atp, a proinflammatory damp. this atp is then rapidly converted to adenosine by the host's own enzymatic machinery. we hypothesize that c. difficile indirectly exploits this host homeostatic mechanism, leveraging the resulting adenosine-rich microenvironment to dampen effective immune responses. this adenosine-mediated immunosuppression could manifest as reduced neutrophil recruitment, a shift towards antiinflammatory macrophage phenotypes, impaired dendritic cell activation, and suppression of effector t cell functions, while potentially promoting the activity of regulatory t cells and myeloid-derived suppressor american journal of applied science and technology 8 https://theusajournals.com/index.php/ajast american journal of applied science and technology (issn: 2771-2745) cells. such manipulation would create an immunetolerant niche, facilitating c. difficile colonization, persistence, and contributing to disease severity and recurrence. understanding this microbial exploitation of host purinergic signaling opens exciting new avenues for therapeutic intervention. targeting the adenosine pathway, for instance, through the use of adenosine receptor antagonists or ectonucleotidase inhibitors, could represent a novel adjunctive strategy to bolster host immunity and improve outcomes in cdi. while direct evidence of c. difficile's specific manipulation mechanisms requires further investigation, the established roles of adenosine in immune regulation provide a strong theoretical basis for this hypothesis. future research should prioritize direct experimental validation of these proposed interactions, paving the way for innovative host-directed therapies that complement traditional antimicrobial approaches, ultimately enhancing our ability to combat this challenging pathogen and potentially other inflammatory infectious diseases. references fredholm bb. adenosine, an endogenous distress signal, modulates tissue damage and repair. cell death differ. 2007;14:1315–23. mehta tr,
