This present was investigated to relationship between Helicobacter Pylori and Hyperemesis Gravidarum. Methods and Materials: 80 women with 7-16 gestational age, participated in this case-control study. It was done in Obstetric Clinical of Shabihkhani Hospital in Kashan from April to July 2008.The case group had Hyperemesis Gravidarum but the control group did not. The criteria for Hyperemesis Gravidarum were pernicious vomiting (more than 3 times a day) and the presence of one pluse ketonuria. Serum titre of anti Helicobacter pylori IgG with standard ELAZA kit in each group then compared. Chi square test was applied for data analysis and significancy was P-Value less than 0.05. Results: The mean of age was 25.4±4.5 in case and 22.4±4.6 in control group. There were no statistically significant differences in age, gestational age, gravity and parity between two groups. The frequency of Helicobacter Pylori was 75% in case and 35% in control group. Difference was significant (p=0.001). Conclusion: In this study, significant relationship between Hyperemesis Gravidarum and Helicobacter Pylori was seen.

Methods and Materials: In a case-control study, 100 consecutive diabetic patients admitted to Amin and Sedigheh Taherah Medical Centers, Isfahan, were selected based on the inclusive and exclusive criteria and compared with one hundred normal people who selected from general population. Data collected by using demographic questionnaire, the Jalowiec Coping Scale, then MANCOVA and co-variance were used to analyze the data.

Methods and Materials:In this experimental study, oocytes were isolated by standard protocols using collagens (Type 1A). Mutations of the cytoplasmic termini of ROMK2 were constructed using the quick-change approach for site-directed mutagenesis. Xenopus oocytes were injected with cRNA encoding ROMK2 or S362A or S362D mutant three days prior to treatment with BFA solution (time 0). Brefeldin A (BFA) was added to the OR3 medium (+BFA) at concentrations of 25µM (inhibit insertion of new proteins into the cell membrane) or ethanol as BFA vehicle (-BFA). Two-electrode voltage clamp (TEVC) was used to measure oocyte ROMK-dependent currents and membrane potential. Results: In oocytes was expressing ROMK2 and/or the S362A mutant, there was significant reduce in current and membrane voltage of K.
