In this regard, 30 secondary school adult students with maximum of two years of from their menarche and with moderate to severe degree of dysmenorrheal were selected. Methods: In the first phase and on the first day of menstruation, participants’ scores were recorded. With a random systematic method, they were assigned to three groups: mefenamic acid, exercise and mefenamic acid + exercise. Next, with beginning the pain, the mefenamic acid group used mefenamic acid according to physician order. The exercise group participated in aerobic exercise with intensity of 55-70 % of maximum heart rate reserve and for 12 sessions of 45 minutes. In the Mefenamic acid+exercise group both variables were implemented. Then, the participants’ pain scores were recorded. The results were analyzed by paired t-test and ANOVA. Results: In all three groups, the applied treatment to reduce menstrual pain of participants were effective. But the difference was not significant (p≤0.05). Conclusion: Since there was no difference between the use of mefenamic acid and exercise, thus the synthetic drug can be replaced by the exercise so that the girl teenagers be safe from side effects of non-steroidal anti- inflammatory drugs.

Since these amounts have a zero inflated (ZI) value in most students, use of Poisson and negative binomial distributions with ZI, in which can model count data to find the associated factors and estimate the parameters, is recommended. Methods: This cross-sectional study was performed between 2008 and 2009 in Iran University of Medical Sciences (IUMS) on 670 sample students who were selected using stratified sampling. The educational and demographic data was collected from University site and related resources. The study was approved in the IUMS Research Council and Board of Ethics and accordingly the students’ data was investigated confidentially. For data analysis SPSS and Stata softwares were used. Results: Up to Poisson regression and negative binomial distributions with ZI for dependent variables of the number of failed semesters, students’ total averages and the enrolment quota had the most roles in the model. Dependent variables of the number of failed course, total average and undergraduate and master levels had the most effect in both models. Conclusion: In ZI regression model for the number of failed semester, the total average and enrolment quota type have important roles so that increasing the average yields the decreasing of the number of failed semester. Moreover, moving from the other quota types to open-for-all enrolment quota yields a decrease in the number of failed semesters. In regressions with the number of failed courses, the average has an important effect to both models and its increase yields a decrease of the number of failed courses. Also, the undergraduate and master levels cause a decrease in the number of failed courses.

The aim of this study was to explore occurrences of shock induced by poisoning and their relation to toxic agents and outcome of patients in Baharloo Hospital, Tehran. Methods: in a cross-sectional study from June 2011 to June 2012 patients admitted as poisoning were assessed at Baharloo Hospital. Some 196 patients who had a systolic blood pressure less than 80 mmHg despite infusion of 2-3 liter of normal saline within 30 minutes were included in this study. Of these, 112 (57.1%) were male and 84 (42.9%) female. Collected data was analyzed using SPSS v. 19.  Results: The poisioning induced shock complication was more frequently occurred within 21-40 years range of age that included 57.1% of the patients. Aluminum phosphide poisoning was the most frequent cause of shock as well as death, with a frequency rate of 37.7% and 82.4% respectively. Totally and despite intensive care, 80 patients (40.8%) died in which 64 cases (32.6%) was because of refractory shock. In fact, all deaths in the context of tricyclic anti-depressants, calcium channel blockers and α2 agonists as well as 90.2% of deaths in aluminum phosphide poisoning, were related to refractory shock.  Conclusion: This study showed that the poisoning induced shock was related with poor prognosis. As there are specific treatment strategies for combat shock in particular toxicities, it is necessary for doctors to learn more about them, and in the case of such situations effectively control the complication.

This cancer is considered as an embryonal neoplasm that arises from nephrogenic blastemal. Despite advances in therapeutic success, survival rate is still not satisfactory in tumors with unfavorable histology and recurrent cases. On the other hand, late adverse effects of chemotherapy threaten the life of Wilms' tumor survivors. The present study aimed to establish a patient-derived tumor tissue xenograft for utilizing in individualized chemosensitivity assay.   Methods : Fresh tumor specimens of 4 patients with Wilms' tumor were obtained by cytoreductive surgery, and after primary culture and initial purification of neoplastic cells, the cells of each tumor were subcutaneously inoculated to 10 athymic nude mice. Growth characteristics of established models were assessed and the tumors were studied by light microscopy.   Results : Tumor take rate was reported 70%. Pathological examination illustrated the presence of all epithelial, stromal and blastemal parts in H&E staining. Immunohistochemical study with CK, desmin, myogenin, WT-1 and vimentin markers confirmed nephroblastoma.   Conclusion : Histopathological study approved the validity of patient-derived tumor tissue xenograft model of Wilms' tumor. Since this model has been established for the first time in Iran, thus it can be considered as a useful research tool for personalized treatment of nephroblastoma and chemoresistance assays.

The aim of the present study was to investigate the effect of short-term consumption of CoQ10 supplement on DOMS in athletic and nonathletic boys aged 15 to 17 years.   Methods : Twenty athletic and non-athletic boys who had no muscle soreness history in previous six months, voluntarily participated in this study and were assigned into two groups of 10 athletic and 10 non-athletic boys . Physical activity program for DOMS was 70 forearm eccentric contractions . Duration of every contraction was 3 seconds and between two contractions they rest for 10 seconds . Also, they had one minute rest between every 10 contractions . Dependent variables ( LD H and CK ) at baseline ( before) and 48h after exercise soreness were measured . For data analysis ANOVA with repeated measure was used and p ≤ 0.05 was considered as significant .   Results : Delayed soreness was investigated by measuring the biochemical changes of studied enzymes and self-report factors (i.e. muscle strength, fatigue, and stinging pain). Statistical analysis showed that there were no significant changes in LDH and CK levels of athletic and non-athletic groups (p ≤ 0.05). Both groups’ verbal representation showed that the short term consumption of CoQ10 yields reduction of muscle pain, stinging and fatigue.   Conclusion: Short term consumption of CoQ10 supplement reduces the levels of main markers of DOMS and muscle pain and fatigue , but this decrease was not significant .
