The effect of antioxidants (vitmine E;C) on preeclampsia in primipar women

Background&Objective: Precelampsia with prevalancy of 5-10% is one of the important causes of maternal morbidity and mortality and neonatal prematurity that prevention of it has aessential role in reduction of maternal and fetal mortality. Pathogenesis of disease is endothelial dysfunction and free radicals can exaggerated of endothelial damage.this study designed to evaluate antioxidants (vit E,C) effect on preeclampsia in primipar women. Materials&Methods: This study was a randomized clinical trial in 580 primipar women that randomized in two treatment and control groups. To the Treatmet group in 18-22w of gestation during routin prenatal care vitamin E (400 IU) and vitamin C (lg) administrated daily untile end of pregnany. Control group recieved routin ferrous sulfate and incidence of preeclampisa compaired in two-group .Data analyzed by chi-square test. Results: Incidence of preeclampsia was 1.7% in treatment group and 6.2% in control group (p<0.05). Conclusion: antioxidant (vit E,C) have an effect on reduction of preeclampsia incidence

The effect of essence of Citrus aurantium on the electrophysiological properties of isolated perfused rabbit AV-node

Background & Objective: Pharmacological studies and traditional medical literature point to the cardiovascular effects of the Citrus aurantium L. (Rutaceae) in many instances. In the present study, we used isolated perfused AV-node of rabbit as an experimental model to determine the effect of various concentrations of essence of Citrus aurantium (0.1-0.3 v/v) on electrophysiological properties of isolated heart. The second goal of the present study was to assess the protective role of essence of Citrus aurantium on arrhythmogenic effects of ouabain. Materials & Methods: This was a semi-experimental study. We used isolated perfused rabbit AV-nodal preparation, in three groups. In the first group, the effect of various concentration of the Citrus aurantium (0.1, 0.2, 0.3 ml/l) was assesed on the AV-node. In the second and third groups, the effect of Citrus aurantium was tested in the presence of ouabain (0.1?molar) and verapamil (0.1?molar). We used 6 rabbit in each group. Statistical analysis was preformed by SPSS Mean±SE was used in the all results. Results: Our results showed depressant effects of extract of Citrus aurantium on Wenchebach Cycle Length (WBCL), AV Conduction Time (AVCT), Effective and Functional Refractory Periods (ERP & FRP). Rate-dependent properties such as Facilitation and fatigue significantly increased by Citrus.a (0.3ml/l). We had significant increase in the AVCT (32.6±3.6 to 40±6.08 msec) and FRP (147±5.1 to 166.6±3.6 msec) by Citrus.a. We had a protective role of Citrus aurantium on ouabain induced AV-nodal depression. The magnitude of facilitation and fatigue in the concentration of 0.3 C.aurantium was 7.5±0.3 and 6.5±0.5, respectively. Conclusion: The above results indicated potential inhibitory and antiarrhythmic effect of Citrus aurantium in treating supraventricular tachyarrhythmia

The evaluation of fish oil (Omega-3 fatty acids) efficacy in treatment of primary dysmenorrhea in high school female students in Hamadan

Background&Objective: Primary dysmenorrhea is one of the common causes of absence from work place and life quality among women. According to some studies, fish oil administration results in production of weaker prostaglandin’s (PG) and reduces the severity of dysmenorrhea. The aim of this study is to experience the efficacy of fish oil on dysmenorrhea, which is a cheap drug and with low side effects. Materials&Methods: In this clinical trial, the students separated into two groups those affected with primary dysmenorrhea by referring to girls' high schools and complete the questionnaires. In the next stage randomly were selected two groups each group included 22 students with primary dysmenorrhea. In first group fish oil capsules and the other group placebo were recommended for duration of two months. These students were evaluated before drug recommendation, at the end of two months treatment and two months afterward. In these three stages pain severity by VAS (Visual Analogue Scale) system and pain duration by Cox scaling system were be recorded in each group. Results: There is not meaningfull statistically difference in the average age, age of menarche, menstrual condition (regular or irregular) and accompaniment with symptoms of PMS (premenstrual syndrome) between fish oil and placebo groups. Before recommendation of capsules the average of pain severity did not have a meaningful statistically difference between two groups. The average pain duration also had similar situation. After two months treatment, the average of pain severity (VAS) in fish oil group was significantly less than which in placebo group (p<0.05). Also the average of pain duration in fish oil group was less than which in placebo group with a statistical difference of (p<0.05). Moreover, two months after the end of treatment the average of pain severity (VAS) and pain duration (hour) had meaningfull statistically difference between fish oil and placebo groups and were less in fish oil group. Conclusion: As compared with placebo, the fish oil capsule after two months of consumption had a significant effect on reduction of pain severity and duration in primary dismenorrhea. Also two months afterward from the end of this clinical trial the effect was more than placebo
