Introduction: Stirility is a problem throughout the world. Decreasing the growth and developmental rate of embryo and arresting in certain step of development like two cell block, could be the reason of infertility in some couples. Previous study show that arrest and retardation in embryo development can produced by low temperature exposure. We aimed to evaluate the effect of Ethanol on growth and development of mouse two-cell arrested embryo. Material and methods: The 4-6 week old female mice were coupled with male mice following superovulation and positive vaginal plaque mice were killed 48 hour after HCG injection by cervical dislocation method. Two cell embryo were collected in RPMI medium and divided and cultured (in M16 medium) in three groups. The 2nd and 3rd groups were exposed to 4°C for 24 hour in order to delay and arrest for cleavage and developmental rate. The 2nd group (2nd control) were incubated immediately, while the 3rd group (experiment) were exposed to % 0.1 Ethanole for 5 minutes and the 1st group (1st control) without any exposure to low temperature group were incubated . Results: The data analysis by one-way ANOWA show that the developmental rate of embryos exposed to low temperature (4°C) significantly decreased (P=0.001), retardation and arrest being produced. The mean of cleavage rate between groups were not significantly affected, but the mean percent of degenerated embryos between groups have significant differences (P=0.045). On the other hand the mean percent of morulla is significantly different between groups (P=0.005) similarly the mean percent of blastocyst and hatched blastocyst have significant differences between groups (P=0.014) (P=0.001) after 120 hr evaluation. Conclusion: Effect of %0.1 Ethyl-alchol on arrested two cell embryos can significantly increase the mean percent of morulla and development up to blastocyst and hatching blastocyst stage related to control group, without any significant effect on cleavage rate

Background: Previous studies in Iran and around the world have indicated the high rate of medicines use. In recent years, medicine use has continued to rise in spite of attempts made by the Ministry of Health and Medical Education in Iran. Therefore, it seems that in addition to the reasons considered in previous studies, there are other reasons for this problem in Iran. One of the parameters involved in this problem is the high medicine use among the clinical staff. Thus the aim of this study is to compare medicine use among clinical and non-clinical staff members. Materials and Methods: In this cross-sectional study, information about the monthly use of medicines was obtained by means of a questionnaire administered to eight groups of clinical and non-clinical members: first-year medical students, first-year non-medical students, interns of medicine, forth-year non-medical students, general physicians, specialists, academic members with M.Sc, and academic members with PhD degrees. Results: The results showed that medicine use decreased with increase in education level in both groups. In addition, the comparison of medicine use between clinical and non-clinical groups showed that there is not a significant difference for most medicines among the first- and second-year students but medicine use significantly increased among general physicians and specialists compared to the control groups. Conclusion: The results of this study showed that medicine use among clinical staff should be considered in controlling medicine use in Iran.

Background: Several studies have demonstrated that the levels of inflammatory markers in healthy women are under the influence of menstrual cycle changes. The aim of this study was to compare blood levels of inflammatory markers in women with appendicitis in different phases of menstrual cycle. Materials and Methods: In this case-control study, 70 female and 12 male patients with appendicitis, and 61 healthy women were enrolled based on inclusion and exclusion criteria. Inflammatory markers, such as leukocyte count, CRP, ESR, and TNF-α were measured and compared using student t-test and one-way ANOVA based on different phases of menstrual cycle. Results: There were no significant changes in the ESR, CRP, and TNF-α concentrations and the number of peripheral blood leukocytes in different phases of the menstrual cycle in women with appendicitis. The mean number of leukocytes and CRP concentrations were significantly higher in patients with appendicitis compared with the control group. Conclusion: The findings show that there are not significant differences in the inflammatory markers in women with appendicitis during the different phases of menstrual cycles. It seems that day to day variation of sexual hormones in the menstrual cycle have led to very different conclusions about the change of inflammatory markers in different phases of menstrual cycle. Therefore, studies investigating inflammatory markers in women with acute appendicitis based on day of menstrual cycle, time of sampling in the day, and severity of appendicitis are suggested.
