Rasool khetamhabeeb112@yahoo.com Dept. of Biology / College of Science / AL-Mustansiriyah University Abstract Acne is a cutaneous pleomorphic disorder skin disease most frequently occurring during the adolescent in ages of 12-24, with estimated percentage (85%). There are different ways to treat acne such as using of antibiotics, herpes, and mixing treatments. Antibacterial activity of four concentrations (100,50,25,12.5)mg /ml of alcoholic and cold aqueous crude extracts of Cinnamon(Cinnamomum verum ), Henna (Lawsonia inermis ) , Lupine (Lupinus luteus) were studied against aerobic and an aerobic bacteria isolated from inflamed and discharging pus from thirty Iraqi acne vulgaris patients refer to dermatology unit at AL-Kindy Hospital from December 2016 to March 2017.All information (age, sex ,diseases and using topical treatments) were recorded .The bacterial isolates were identify using morphological characteristics, biochemical tests and the Vitek-2 compact system. Among (30) Acne samples taken, 8 (26.7%) samples were from males age range (19-33) years and 22(73.3%) were from females within age (17-29) years. twenty-five (83%) samples were culture positive, and only (17%) of samples revealed no growth. Most frequent bacteria which isolated (aerobically) from acne patients were Staphylococcus aureus ( 60%), Staphylococcus epidermidis (20%), Escherichia coli (8% ), Pseudomonas aeruginosa (4%), and an aerobic bacterial isolates were Propionibacterium acnes (8%) isolates. Antibiotic sensitivity tests were performed against, Ampicillin, Clindamycin, Gentamicin, Cotrimoxazole, Erythromycin, Vancomicine, Tetracycline, Doxycycline, and Azithromycin.All bacterial isolates were resistance to Ampicillin. Staphylococcus aureus and S. epidermidis were sensitive (100%) to Doxycycline and Azithromycin, P. acne were also highly sensitive to these two antibiotics (95.5%,97.1%) respectively, while E. coli and P. aeruginosa were (100%) resistance to these antibiotics. Gentamicin and tetracycline were susceptible by most of the study isolates except for P. aeruginosa which was very resistance to CN and TE (100%&94.8%) respectively. The antimicrobial potential of cold water and alcoholic crude extracts of Cinnamon (Cinnamomum verum ), Hinna (Lawsonia inermis), and Lupine (Lupinus luteus), in concentrations (100,50,25,12.5) mg/ml against the gram positive and gram negative isolates were tested through a well-diffusion method. Alcoholic extract of Henna leaves in concentration (100mg/ml) showed high inhibitory activity to all isolates compared with the aqueous extract and the all concentration of cinnamon aqueous and alcoholic extracts, while lupine extracts had no effect on all bacterial isolates. Gram-positive bacteria were the most common microorganisms involved in acne infection. There are variations in the incidence of acne infection in relation to sex, age; Alcoholic extract of the Henna leaves could be used to treat acne. Key words: Acne vulgaris, Bacterial isolation, antimicrobial effects, Henna, Cinnamon, Lupine.

Introduction Acne vulgaris disease effect the pilosebaceous follicle in the face and neck,it appears like non-inflammatory (open and closed comedones) and inflammatory lesions (papules, pustules, and nodules)[1]. Commonly most frequent appearance in age (12-25) year, which estimates of 85% of adolescents and young adults [2]. Its pathogenesis is multifactorial factors like hormonal [3] bacterial colonization by Propionibacterium acnes (P. acnes), and immunological (inflammatory) [4], that results in the formation of acne lesions but the key factor is genetics [5]. Acne may affect the psychological and social quality of individual's life, due to acne scars formation (6). Although it can be treated with wide-range of therapies like (antibiotics, Hormonal Therapies, Corticosteroids, Surgery, Herps), which used to reduce the inflammatory lesions and scar formation [6] Many plants have been used in treatment of several pathological conditions, due to its antioxidant compounds which play a major role in human health worldwide [7]. While using of antibiotics for treatment acne vulgaris for long time can lead to bacterial resistance and many side effects problems [8]. Medical plants with anti-inflammatory and antibacterial activities are used in different ways in the treatment of acne alone or in combination with drugs safely [9], where bacterial cells could be killed by the rupture of cell walls and membranes or by the disruption of the inner when treated with these plants or its extracts [10] organelle Aims: to determine the antimicrobial values of some traditional herpes (Cinnamon, Hinna and lupine) alcoholic and water extracts on acne bacteria. 2. Materials and Methods Subjects: Thirty Iraqi patients diagnosed by dermatologist as acne vulgaris where enrolled in this study. They refer to AL-Kindy Hospital in Baghdad /Iraq during the period from December (2106) till March 2017. Eight 8 (26.7%) were males age range (19-33) years and 22(73.3%) were females within age (17-29) years. Bacterial isolation: For isolation of bacteria from patient's skin, the area of the forehead of a volunteer was cleansed with a sterile swab, and the swab was placed in its tube that containing transporting medium and transport immediately to the laboratory of microbiology for culturing. The samples were cultured on blood agar, MacConkey agar and thioglycolate broth. The cultures were then incubated at 37°C under both aerobic and anaerobic conditions for seven days [11]. Thioglycolate broth used as a medium for enhancing the growth of Propionobacter from skin swab. After incubation an aerobically in CO2 incubator for 5-7 days at 35-37C, if growth is detected in the broth, sub culturing was done on 5% human blood agar to categorize and isolate Propionobacter. [12] The colonies were determined morphologically and identify by biochemical tests, Vitec-2 system was used for final identification. Antibiotic susceptibility test: The standard Kirby-Bauer test (disc diffusion test) for antibiotic susceptibility, has been used for determination the effects nine of standard synthetic antibiotics [13]. Preparation of Plant Extract [14]. The leafs of Hinna, Cinnamon sticks, lupine seeds, samples were obtaining from herbal medicine store in Baghdad /Iraq, washed with water, leave to dry, and grounded to powder by blender. The samples powder was added to Ethanol (>99.5%), and cold distilled water IHSCICONF 2017 Special Issue Ibn Al-Haitham Journal for Pure and Applied science https://doi.org/ 10.30526/2017.IHSCICONF. 1774 For more information about the Conference please visit the websites: http://www.ihsciconf.org/conf/  www.ihsciconf.org  Biology|89   to make a 20% concentration, in sterile 250mL flask wrapped with aluminum foil to avoid evaporation and light. The flask content was mixed thoroughly by platform shaker at (70 rpm) for 3 days, then the mixtures were centrifuged for 10min at 4,000 rpm at room temperature, get off sediment and collected supernatant dried in oven (40) ∘C, and powder kept till use. Antibacterial Activity: Acne bacteria isolates were recultured on nutrient agar plates and incubated at 37∘C for 18 to 24 h. for pure colonies isolation. Single pure colony was transferred by cotton swab to a test tubes contain sterile normal saline (4ml) and mixed well, to get about 1.5 × 108 CFU/ml. compared turbidity to that of the 0.5 McFarland standard solution. Mueller Hinton plates were streak with bacterial isolates, five millimeter diameter wells were punched into the medium using a sterile Cork borer, a well-diffusion method was used for testing antibacterial activity of extracts. 50 𝜇L of extracts solution were employ per well, controls were pure solvents only. The plates were sealed, labeled, and incubate at 37∘C.for 24 hours, inhibition zones in millimeters (mm) were measured by ruler and the average was estimated. Results and Discussions samples collection and bacterial identification Skin swabs were collected from thirty Iraqi acne vulgaris patients. Eight (26.7%) of samples were from males age range (19-33) years and 22 samples (73.3%) were from females within age (17-29) years. Swabs were grown both aerobically on (blood and MacConkeys agar) and anaerobically (in thioglycolate broth and sub cultured on thioglycolate agar), 25 (83%) of samples were culture positive, and only 5 samples (17%) revealed no bacterial growth (Table 1).

This bacterium is an anaerobic bacteria found in acne lesions, lead to stimulates inflammation by producing proinflammatory mediators like interleukins and tumor necrosis factor [17,18], and sebum free fatty acids [19,20]. This bacterium with Staphylococcus epidermidis are common pus-forming microbes and formation of different types of acne vulgaris. However, it is by no means clear that either bacteria or their products initiate follicular inflammation. therefore, its role in acne cannot be explained by its presence in the follicle. [21] In our study a higher percentage of isolation was for Staphylococcus aureus (60%) followed by, Staphylococcus epidermidis (20%), Escherichia coli (8%), Propionibacterium acne (8%) and Pseudomonas aeruginosa (4%). This indicate that Staphylococcus aureus isolates, have major role in acne vulgaris formation instead of Propionibacterium cane bacteria [22,23].

Our results showed that all bacterial isolates were resistance to Ampicillin. Staphylococcus aureus and S. epidermis were sensitive (100%) to Doxycycline and Azithromycin, P. acne were also highly sensitive to these two antibiotics (95.5%,97.1%) respectively, while E. coli and P. aeruginosa were (100%) resistance to these antibiotics. Gentamicin and tetracycline were susceptible by most of the study isolates except for P. aeruginosa which was very resistance to Gentamicin and tetracycline (100%&94.8%) respectively. On the basis of these results, we suggest Gentamicin and tetracycline are suitable antibiotics for acne patients. Table (2) Resistance to antibiotics in bacteria that may cause acne vulgaris has been increased globally, with geographical regions differences [26]. Antibacterial activity of plants extracts Results of this study indicated that only the crude solvent extracts prepared from the leaves of Henna and callus of Cinnamon cold water and alcohol, showed inhibitory activity on isolated acne vulgaris bacteria (Table 3), (Table 4), (Table 5), (Table 6). While all isolates where resistance to cold water and alcohol lupine extracts in different concentrations (100,50,25,12.5) mg/ml.

Antibacterial activity of water and alcoholic extracts of leaves of henna against Staphylococcus aureus and Staphylococcus epidermidis isolated from acne vulgaris patients have been studied by [29]. Their results showed that alcoholic extracts were highly effective than water extracts and Staph. Epidermidis bacteria was more susceptible to extract activity than Staph. aureus, with inhibition zone diameter (22) mm for extract of 1000 μg /ml. (29), this results was in contrast with our result were cold aqueous extract of Henna had the higher effect on all bacterial isolates compared with alcoholic extract. previous studies showed that the extracts of henna and roselle may have promising antibacterial activity [30] Our results showed that alcoholic extract of Cinnamomum in concentration 100mg/ml have the highest inhibition to growth of all isolated acne bacteria, while 12.5 mg/ml of cold alcoholic and water extract had no effects on growth of acne bacteria under the study, this may be due to dilution of the effective material in these extracts. Identification of the antimicrobial activity in Cinnamomum zeylanicum (C. zeylanicum) bark against bacterial skin infection were studied for the potential uses as alternative remedies in the treatment of skin infections. The cinnamon oil extract at 25%, 50% and 100% concentrations were found to inhibit S. aureus with clear zone diameters of 22.3mm, 23.3mm and 25.3mm respectively whereas the inhibition zone of Vancomicine (positive control) was 19mm. [31]. In our study Gram negative isolated bacteria were more resistance to all plant extracts than Gram positive one. This resistance may be due to its cell wall structure, which prevent the penetration of the plant extract, and increase resistant to these extracts. References [1] K.
