[Study of the mental health status of dormitory students in university of social welfare and rehabilitation sciences]

Introduction: University student in dormitory perceive multiple stressors during educational experience, that can lead to disruption in mental health status. The purpose of this study was to determine, mental health status of university students in dormitory

Method: This is a descriptive-analytic study, 162 university students from 7 dormitory of University of Social Welfare and Rehabilitation Science were selected by proportional sampling. The instruments for collection data were demographic data, General Health Questionnaire. Analysis was done by t-independent Mann Whitney U, Kruskal Wallis, Pearson correlation, Chi-squre, Kolmogrov-smirnov by using SPSS software and 95 percent coefficient

Results: Findings showed that 54.3 percent [88 person] of university students were suspect for mental disorders. The high mean was related to social function disorder and then sleep disorder and anxiety, physical symptoms and depression. There was negative significant relation between age, education term, dormitory living time and mental health status [P<0.05]

Conclusion: According to our findings, university students in dormitory are at risk for mental disorder, because some factors. Therefore, it is necessary to try for removing factors that relate to this problem

[Effects of Zataria multiflora boiss. essential oil and nisin, alone and in combination against listeria monocytogen in BHI broth]

In food industry, quality assurance and prolongation of shelf-life is achieved through control of pathogenic and spoilage microorganisms in foods. Regards to much proved adverse effects of synthetic food additives and general concern on the subject, the replacement of these additives with natural based ones such as plant essential oils and natural antibiotics has been raised and researches first at in virto models and then in food systems is necessary. The aim of this study was to determine the antimicrobial activity, minimum inhibitory concentration [MIC] and minimum bactericidal concentration [MBC] of Zataria multiflora Boiss. Essential oil and nisin alone and in combination against Listeria monocytogen in brain heart infusion [BHI] broth. The specifications of combination of essential oil and nisin were determined. In this study 600 micro g/ml of Z. multiflora essential oil and 2.5 micro g/ml nisin in pH value of 5 at 15 [degree sign] C were used. In this study Zataria multiflora essential oil had antimicrobial effects agains Listeria monocytogen [MBC: 19, MIC: 9.5 micro g/ml]. Combination of nisin and the essential oil had also antimicrobial effects against Listeria monocytogen [MIC: 1.2, MBC:2.4 micro g/ml]. Zataria multiflora essential oil and nisin were effective against Listeria monocytogen alone. This effect was obviously increased in combination with each other and the results were noticeable

[Biosorption of lead by active biomass of fungi isolated from lead polluted effluent and soil]

Lead is one of the heavy metals which releases into water and soil resources through industrial wastes and poses serious harmful effects on human health. This study was conducted to determine the biosorption capacity of lead by active biomass of lead resistant fungi. In this study the lead -resistant fungi were isolated from effluent of Zanjan Lead and Zinc factory and lead biosorption capacities of isolated fungi were studied by biosorption experiments. A collection of fungi colony was isolated in SDA media and then every colony was cultured in separate media. The fungi colonies were identified via morphological characteristics and Lacto phenol Caten Blue. The MIC of fungi was determined and their lead biosorption capacities were measured by culturing the fungi in SDB media that were polluted with 50-200 mg/L of lead. The isolated fungi were one Spp. of Rhizopus, two Spp. of Penicillium and one Spp. of Aspergillus. The MIC of Rhizopus was 2500 and for others was 3000 mg/L. The maximum lead biosorption capacities were 51,5, 19.2, 25.6 and 12.5 [mg per g of dry weight of fungi biomass] for Rhizopus, two Spp. Of Penicillium and Aspergillus respectively. The maximum lead biosorption capacity of Penicillium and one Spp. of Aspergillus was higher than 70%, thus biosorption of lead is an efficient method for treatment of lead polluted effluents

[ effects of sodium benzoate [C[6]h[5]COONa] on ovaries and its hormones and gonadotropins on female balb/C mice]

Sodium benzoate [C[6]H[5]COONa] is used as a disinfectant against microorganisms existing in healthy foods and drugs. The aim of this study was to determine the effect of sodium benzoate on ovaries and its hormones and gonadotrophins on balb/C mice. Eighteen adult female mice [balb/c] were divided into 3 groups of 6 animals each. Two groups of animals were treated with 280 or 560mg/kg/day sodium benzoate for 60 days [Group II and III, respectively]. Animals of group I were administrated water without sodium benzoate for 60 days and served as the controls. On the 61st between 08:00 to 10:00, blood samples were collected from the left ventricle after anesthesia with diethyl ether. After that the mice were killed following ethical procedure, the ovaries were dissected out, then, it was immediately fixed in formalin 10% and embedded in paraffin. Sections of 5 micro m thickness were taken from the mid portion of each ovary. Plasma levels of FSH and LH were significantly decreased in group III compared to control group [P<0.0001]. Plasma level of progesterone was significantly decreased in treatment groups compared to control group [P<0.001]. Decrease of oogenes and disorganization of ovaries in electron microscopy investigation determined. The results of present study indicate that sodium benzoate affect and decrease the oogenesis and reduce of follicles and corpus luteum. Thus, it is suggested to replace it if necessity

[ menstruation health status of high school girls in Zabol 2004]

Menstruation in young girls is a phenomen to detect real puberty and is important in adolescents as a natural right. This research has been done to determine the menstruation health situation of high school girls in Zabol -2004. This descriptive study was done on 331 high school girls of Zabol which were selected as cluster - random samples. Data collection was done through pre- test questionnaire and were analyzed considering the characteristics of variables and research objects .Validity and Reliability of questionnaire determined by content validity and test- retest. The statistical methods used are T - test and variance analysis. Results indicated that, the menarch age was 13.4 +/- 1.1 years. 6.3% of samples had permanent, and 9.6% had often PMS signs. The majority of samples [70.1%] had low menstruation health level. Most of them [54.4%] have been received their information from their mothers. Also there was a significant relation between menstruation health level and parents education level, but there were no relation between other factors and menstruation health level. Unfortuantely adolescent girls don't receive correct menstruation health informations that causes incorrect and unhealthy behavior during menstrual period. This determines the necessity of educating female students about the menstrual period and health precautionary measures including appropriate nutrition, exercise and physical activity, personal hygiene, etc
