Alopecia Areata is a chronic inflammatory disease which affects the hair roots. Different drugs and methods are used to treat this disease, nevertheless there is still no cure. The aim of this study was to compare the therapeutic effect of topical Minoxidil 2% solution in the treatment of alopecia areata on the scalp with rosemary solution. The present clinical-trial study was conducted on 78 patients with Alopecia Areata. Block randomization was designed in two groups of four Minoxidil 2% (n=39) and Rosemary (n=39). During the initial evaluation, patients were assessed in terms of location, number and extent of lesions by a dermatologist, and then the data were recorded. Patients in the intervention group were administered rosemary, as well as those in the control group were given Minoxidil 2%. The patients were instructed to apply the medication to the lesion twice a day. The lesion was re-evaluated two months later. Data were analyzed using SPSS version 18 as well as T-test and Chi-square test and descriptive statistics. There were no significant differences in terms of mean age, mean duration of disease, and alopecia conflict in the patients of two groups (p>0.05). There was no significant difference in cure rates between the two groups (05/0 p>0.05). The findings of this study revealed that both Rosemary and Minoxidil had the same effects on alopecia areata. Due to the fact that the treatment of alopecia areata by rosemary plant is effective and affordable, it can be recommended.

In vitro maturation and fertilization of oocytes play an important role in reproductive biotechnology. The aim of this study is to define the IGF-1 effect on in vitro maturation, fertilization and development of mice immature oocytes to 2-cells in TCM199 medium cultures. In this study 4 week old NMRI mice were used. Ovaries stimulation carried out using PMSG. GV oocytes with or without cumulus cells were isolated from ovaries and cultured in TCM199 in presence of 100 ng IGF-1 for 24hr.The oocytes (MII) were inseminated with sperm in T6 medium for fertilization and development of 2-cells stage and they were investigated under inverted microscope. Data analysis was performed by using Chi- 2 test. In cumulus cell group and in the presence of insulin-like growth factor fertilization of oocytes, forming embryos and the formation of 2-cells compared to the group without cumulus cells significantly increased (p < 0.05). As the results showed oocytes with cumulus cells in the presence of insulin-like growth factor enhances maturation, fertilization and embryonic development in 2-cells oocytes compared to group without cumulus cells TCM199.

One of the major events during aging is retirement, which can cause several problems. The aim of this study was to evaluate the efficacy of a therapeutic approach to increasing life expectancy of Retired Teachers of Mamasani. In this study, a random sampling of 40 men retired from retirement center that pre-test scores were out of one standard deviation below mean have been selected and equally divided in two groups of experimental and control groups. The experimental group received 10 sessions of 90 minutes and a mean treatment group was administered once a week. After completing the training program, the post test was performed. Data were analyzed using multivariate ANOVA (MANOVA). The result showed that the mean treatment group increased life expectancy in the intervention group compared with the control group (p <0.05). After running the sessions, followed by an interval of one month treatment group demonstrated a significant beneficial sense. it can be used of group therapy as an Independent manner or with other therapies to increase life expectancy.

The production of free radicals and lipid peroxidation are harmful to health. The aim of this study was to determine the effect of the ethanol extract of Quercus species on lipid peroxidation and the histology of the gyrus dentatus after rat cerebral ischemia. In the present experimental study, thirty male Wistar rats were divided randomly into three groups. Experimental groups 1 and 2 received 500 and 1000 mg kg hydro alcoholic extract of Quercus and control group were given distilled water at the same time, respectively. In all groups, both sides of common carotid artery was blocked and then opened for 15 minutes. After fifteen days, the mice were killed and the right and left hemisphere were used to determine the level of malondialdehyde by histological studies. Data were analyzed by one-way AOVA. The average number of granular cells in the dentate gyrus of experimental groups were 32.5±1.5, 31.2±2.8, respectively, which was not significantly different in comparison to the control group (p>0.05). Hydro alcoholic extract of Quercus species inhibit lipid peroxidation by preventing the process of reducing ischemia-reperfusion after injury of nerve cells.

The Cucurbita pepo L. fruit pulp contains anti-oxidant, vitamins A, C and E, cucurbitacin, β-carotene and α-carotene, B complex vitamins, vitamin B6, pantetonic acid and contains minerals as well. The aim of this study was to evaluate the effect of pumpkin fruits on spermatogenesis and testicular tissue changes in male rats. The present experimental study was conducted on forty adult male Wistar rats in four groups of ten. The control group received no drug treatment whereas the experimental groups were treated with 20, 40 and 80 percent of Cucurbita pepo L. fruit pulp orally for 28 days. At the end of the twenty-eighth day, the animals were operated and tissue sections were prepared after testes were removed. Histological changes between the experimental and control groups were examined by light microscopy. Using t-test, ANOVA and Tukey test data were analyzed. The consumption of pumpkin fruit at amounts of 40 and 80 percent increase in the number of spermatogonia, primary spermatocytes and spermatids were (p <0.05). It also showed that at 80% increase in the concentration of spermatozoa in the seminiferous tubules was observed. The results indicated that the pumpkin fruits containing ingredients such as cucurbitacin, pantothenic acid, vitamins and minerals that can increase testosterone level and improve the process of spermatogenesis.

Obesity and asthma, are cardiorespiratory changes that could affect the airways and may play a role in occurrence of symptoms during exercise. However, there is little information about the effect of high and low humidity on cardiorespiratory factor in obese children with asthma during progressive aerobic activity. The present case-control study was carried out with ten obese asthmatic children and fifteen healthy children who performed an exercise protocol in different environments (relative humidity 65 ± 5% versus 35 ± 5%). During exercise, cardiorespiratory parameters were controlled using K4B2. Heart rate, systolic blood pressure and double product were measured with a digital sphygmomanometer and stethoscope polar. Data were analyzed with dependent T test and ANOVA with repeated measures analysis. A significant increase was detected in the markers of HR, SP and DP after exercise in obese children with asthma and healthy children (P< 0.005). However, indexes of cardiorespiratory and exhaustion was significantly higher in obese children with asthma and healthy during exercise in the environment with 65 ± 5% relative humidity, as compared to 35 ± 5% relative humidity. These results indicated that cardiorespiratory function in children with asthma and healthy children were different. Cardiorespiratory responses to exercise in children are influenced by environmental conditions such as humidity, so that humidity has a negative impact on the duration of the activity and load on the heart muscle.

Violence against women is always of social problems which faced the individual and social health of community members. The aim of this study was to identify psychosocial factors affecting violence against women in the Nurabad. This cross-sectional study was performed on a year of their lives of married women in Nurabad city in 2014 with the level of primary education or more. The assessment tool was questionnaire and 400 students were selected by cluster sampling method. Variations of gender orientation, decision-making power of women and social class of respondents were assessed. Data were analyzed using one-way analysis of variance with the aggregate variables and regression analyses were used to design a model. The correlation of sexual orientation or violence against women and to the decision-making power or violence against women were 0.731and 0.657 respectively. Variable social base - economic variables on the variables of gender orientation 0.384 and on the decision-making power of women 0.295 were affected. It also showed that the variables of gender orientation at the rate of 0.423 will predict the changes in the decision-making power of women. Variable of gender orientation, decision-making and social class as factors determining violence against women and its incidence in the family.

organizational citizenship behaviour is one of the important socioligicil dimen sions of educatinal organizations, including universities.University staff have the ability of performing important roles in upgading the qualily of their university. The present research was carried out with the aim of finding the correlation between job motivation and organizational citizenship behaviour of the staff of Yasuj University of Medical Sciences (YUMS). The present paper was a descriptive analytical research carried out during 2012-2013 on 260 samples among 769 cases of the staff of headquarters and vice-chancellory departments of YUMS. The data were collected using standard questionnaires: Padsacoff’s Citizenship Behavior (1999) and Habibi’s Job Motivation (1998). The data were analysed using statistical tests, piersons solidarity coefficient and multiple regression. Results of the research showed that there was a significant correlation between job motivation, the dimensions of job motivation and organizational citizenship behavior (p<0.05). Dimensions of job motivation and job motivation are significantly able to predict citizenship behavior (p<0.05). once the staff have sufficient motivation, and a feeling of satisfaction on their jobs, they perform their duties with more precision which causes maximum efficiency.
