Millions of people are worldwide suffering from this illness. This disease happens in all ages of men and women. This research tries to introduce a traditional medication in comparison with common chemical antidepressant drugs. This experiment was designed to evaluate probably the antidepressant effect of Citrullus colocynthis fruit extraction. Materials and methods: Thirty-two male mice (Balb/c) was randomly divided to four groups (n=8 each). Animals adapted and treated to diazepam, imipramine, aqueous and hydro alcoholic extract of Citrullus colocynthis fruit. All administrations were done via intraperitoneal 0.2ml/animal. Plant material after grinding was extracted with ethanol and evaporated under reduced pressure. Tail suspension test was carried out to assay the antidepressant effect of plant extraction in animals. The test was carried on before, and as well as 30, 60 and 120 minutes after injections. Results: Our data indicated that after intraperitoneal administration of aqueous and ethanol extract, immobility duration exhibits statistically significant increase compared to agitation phase in all times after injection(P<0.05). Ethanol extract reduced statistically agitation time in 30, 60 and 120 min after injection compared to imipramine. Both aqueous and ethanol extract elevated immobility in minute 60(P<0.5). Conclusion: The present study suggested that Citrullus colocynthis extract could possess potential antidepressant and sedative effects which would be of therapeutic interest for using in the treatment of patients with depressive disorders. We suggest more research in this regard.","PeriodicalId":15047,"journal":{"name":"Journal of Basic Research in Medical Sciences","volume":"3 1","pages":"49-55"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67673224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These events may cause serious environmental problems that threaten human health and safety. Therefore, knowledge about the risk of toxic substances from industrial facilities is essential. Although, chlorine is extensively utilized in water treatment as a disinfectant and some chemical processes as an oxidizing agent, it can lead to some concerns in environmental issues. Materials and methods: In this study, distribution of chlorine in the water supply of Eyvan city from Ilam province, Iran, and its surrounding areas is evaluated and high-risk regions are defined by Process Hazard Analysis Software Tool (PHAST) specialized software. Results: The modeling results showed that the cloud of chlorine is about 1220 m across just downwind of the release for the first scenario (rupture of a chlorine vessel) in the summer; however, the probability of fatality is 100 % in a whole year in a distance of 40 m from the vessel. For the second scenario (rupture of pipeline including the chlorine gas) the human death mostly occurs in a distance of 25 m from the pipeline with the probability of 2.8 % in the summer due to low rate of released gas. Conclusion: As an important result, the land around the chlorination unit covering a distance of approximately 1220 m is vulnerable and risk prevention in that region should be accounted for.","PeriodicalId":15047,"journal":{"name":"Journal of Basic Research in Medical Sciences","volume":"3 1","pages":"7-14"},"PeriodicalIF":0.0,"publicationDate":"2016-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67672614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to determine the impact of establishing standards of health promoting hospitals on hospitals' indicators in one of the public hospitals of Iran. Materials and methods: This research was a case-control study that included Fatemieh (case group) and Khatam-Al-Anbia (control group) hospitals. The standards of health promoting hospitals were established as independent variables in the case hospital. The collected data were related to the indicators of neonatal mortality, cardiopulmonary resuscitation (CPR), patient satisfaction and patient education in both hospitals in the second half of 1391(20122013) and the first half of 1392(2013). Then, SPSS version 16 was used to analyze the data through Chi-Square and t tests and the results were displayed as comparing tables. Results: With regard to establishing standards of health promoting hospitals in the case hospital the total score of these standards was 72.26±4.1. The results indicated that establishing health promoting standards did not affect the neonatal mortality rate while it significantly affected success of cardiopulmonary resuscitation, patient satisfaction and the mean scores of patient education (P=0.001).
