Abstract
Abstract Background and objectives: Microbial, physical and chemical properties of drinking water, considering type and quantity of the drinking water, are the factors for determining the acceptability of water. The effect of each of the above components on increasing the quality of water or threatening the health of consumers is also considerable. We aimed to investigate the trace amounts of microbial, physical and chemical parameters of drinking water in Gorgan, comparing to national and international standard. Material and Methods: In this cross sectional study, 50 samples were taken, per month, from four pilot stations in urban water network of Gorgan during one year (2009- 2010). We used instant sampling and performed Enumeration of Coliforms in water culture with most probable number (MPN).Samples taken from the stations during the month were investigated in two general categories of device test and heading-meter. All experiments were performed using standard reference method. Results: of 598 water samples 551 (92.2%) have not Coliforms, 47 (7.8%) contain Coliforms and 16 (2.7%) of them have thermo-tolerant Coliforms. Mean water hardness is 413mg/L, base on carbonate calcium. The amount of fluoride about 0.35 mg and the residual chlorine about 0.6 mg is less than national standard amount. Conclusion: The results show that Gorgan water network is, in view of microbial contamination, safe during almost all days. All the tested samples in terms of physical and chemical parameters are in the range of nation and international standards. Hardness of drinking water of Gorgan is one of the highest.

Abstract
Background and Objective: Nowadays, nosocomial infection is one of the greatest problems in hospitals. Normal flora of staff’s hands and the bacterial agents on the surface of medical equipment can become progressively colonized with potential pathogens during patient care. This study was carried out to determine the bacterial agents existed on staff’s hands and in the wards of hospital to step in to control nosocomial infection.
Material and Methods: In this descriptive study, during 17 months (22.mar.2010- 30.aug.2011), 403 samples, using sterile swab , were randomly obtained from the staff’s hands and medical equipment of emergency departments , ICU, male operation room and female surgical unit . The samples were cultured on Blood agar (BA) and Eosin methylene blue (EMB). Then, identification of isolated bacteria was done with diagnostic tests.
Results: Of 430 samples, 530 bacteria were isolated from staff’s hands (N= 291) and medical equipment (N= 234). The most common bacterium from personnel’s hands (144 49.5%) and medical equipment (24 10%) is Staphylococcus aureus. Also, three isolates of pseudomonas aeruginosa from staff’s hands of male surgical ward and medical equipment of ICU, and two isolates of Acinetobacter.spp from ICU’s medical equipment were identified.
Conclusion: With regard to the findings, it seems that applying the appropriate disinfectant agents by using standard procedures is necessary.

Abstract
Background and objective: There is increasing evidence for the role of oxidative stress in female reproductive tract. The purpose of this study was to determine the activity of antioxidant enzymes during menstrual cycle. In addition, the relationship between activity of antioxidant enzyme and sex hormones was evaluated.
Materials and methods: In this study the activity of superoxide dismutase, glutathione peroxidase, glutathione reductase, catalase and total antioxidant capacity during the menses, follicular and luteal phases of the menstrual cycle in twenty women with regular menstrual cycle were studied. Furthermore, the correlation between activity of antioxidant enzymes and estradiol, progesterone, LH, FSH and testosterone were evaluated.
Results: There was no significant difference between activity of superoxide dismutase, glutathione peroxidase, glutathione reductase, catalase and total antioxidant capacity during the menses, follicular and luteal phases of the menstrual cycle (P>0.05). We found significant correlation, in luteal phase, between superoxide dismutase and FSH (P<0.05، r=0.44) and LH P<0.05،r=0.54). Also it is observed between LH and glutathione peroxidase (P<0.05، r=0.44).
Conclusion: Based on the results, there is no significant difference between antioxidant enzymes and total antioxidant capacity of plasma during menstrual cycle. In other words, physiologic system of women with regular menstrual cycle can protect body against oxidative stress and this is probably performed due to action of FSH and LH hormones.

Abstract
Background and Objective: Prevention of medical laboratory errors is a major goal of quality control programs. Hemolyzed specimen is one of the common issues causing medical laboratory errors. Apart from the visual assessment, the measurement of serum hemoglobin concentration can be another method to evaluate the intensity of hemolysis. We aimed to assess hemolyzed serum specimens using two quantitative and qualitative methods.
Material and Methods: the serum samples (n=890) were evaluated for the presence and degree of hemolysis, using quantitative and qualitative methods. In qualitative method, the samples were investigated visually and in quantitative with the measurement of serum free hemoglobin concentration. Furthermore, the relative frequency of hemolyzed specimens was calculated.
Results: the hemolyzed samples were 23.4 % in qualitative and 65.8% in quantitative method. In quantitative, 71.2% of the specimens had mild hemolysis (sfHB<50 mg/dL), 26.8% intermediate (50mg/dL< sfHB <250mg/dL), and 2% high (sfHB >250 mg/dL). The percentage of hemolyzed specimens was higher in intensive care unit than those of other departments (P < 0.05).
Conclusion: given that hemolysis in small amount is not detectable visually, we recommend using quantitative method for evaluating hemolyzed specimens.

Abstract
Background and objectives: Leishmaniasis is a tropical disease caused by protozoan parasites from the genus Leishmania. In this study, we aimed at investigating the in vitro anti-leishmanial effect of essential oils of Rosmarinus officinalis, Mentha pulegium, Foeniculum vulgare, Lippia citriodora and Pelargonium graveolens.
Methods: The essential oils were prepared from freshly dried and powdered plants with steam-distilled water. Iranian strain of Leishmania promastigotes was cultured in RPMI medium and the inhibitory effects of different concentrations (25, 32, 62.5, 125, 250, 500 and 1000 μg/ml) of the essential oils were investigated at 24, 48 and 72 hours. The number of live parasites before and after treatment with the essential oils was counted by trypan blue 10% staining and using neobar lam.
Results: The essential oils significantly decreased the number of promastigotes in a dose-dependent manner (P<0.05). However, the inhibitory effects of F. vulgare and R. officinalis essential oils were more profound compared to other essential oils. Moreover, concentrations of 500 and 1000 μg/ml of these two essential oils exerted equal and more anti-leishmanial potency compared to glucantime, the first-line drug used for treatment of leishmaniasis.
Conclusion: Based on the results, it is recommended to evaluate the in vivo anti-leishmanial effects of the tested essential oils, particularly F. vulgare and R. officinalis.

Abstract
Background and objectives: Multiple sclerosis (MS) is a common debilitating neurodegenerative disease caused by inflammatory demyelinating processes in the central nervous system. The present study aimed to evaluate the effects of core stability training on serum levels of progranulin and tumor necrosis factor alpha (TNF-α) in women with MS.
Methods: The study population consisted of 24 women with MS (aged 25 to 40 years) in Bojnourd (Iran) with expanded disability status scale score of 2-5. Patients were randomly divided into two groups of core stability training (n=12) and control (n=12). The training group performed 30-40 minutes of core stability training, three sessions a week for eight weeks. Blood sampling was done 24 hours before the first session and 48 hours after the last training session. Serum levels of progranulin and TNF-α were measured using commercial ELISA kits. Analysis of covariance was used to assess data at a significance level of 0.05 .
Results: The eight-week core stability training was associated with a significant increase in serum level of progranulin (P=0.037) and a significant decrease in the level of TNF-α (P=0.000).
Conclusion: The findings indicate that the eight-week core stability training could significantly change serum levels of progranulin and TNF-α and improve the condition of women with MS. Therefore, this type of training could be applied as a complementary therapy for MS patients.

Abstract
Background and objectives: Mycotic keratitis is a fungal infection of the cornea that can cause blindness. Its incidence, risk factors, and the etiological agents vary worldwide and nationwide. Therefore, proper documentation of these data is essential for better disease management. In this review, we aimed to make a clear picture of this infection in the Middle East.
Methods: Data on fungal keratitis from 1986 to 2018 in the Middle East were systematically collected from five English databases (PubMed, Scopus, Science Direct, Web of Science, and Google Scholar) and four Persian databases (Magiran, Scientific Information Database, IranMedex, and Irandoc). A total of 35 studies were included in the review.
Result: The pooled prevalence of fungal keratitis in the Middle East was estimated at 26% (95% confidence interval: 19-32%; I2=98.88%, p<0.001) using random-effect model, with considerable variation among the countries. The prevalence of fungal keratitis was highest in Egypt (36%) and Iran (34%) and lowest in Oman (9%). Aspergillus and Fusarium spp. were the most common causative agents (28%) among filamentous fungi, and Candida (13%) was the predominant yeast species causing fungal keratitis. Based on the data, fungal keratitis was more prevalent in males (39%) than in females (23%).
Conclusion: Our study is the first systematic review on mycotic keratitis among the Middle Eastern countries. These epidemiological estimates can be used by policy makers to improve treatment strategies, especially in this part of the world.
