Abstract

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.

Abstract

Background and Objective: Ulcerative colitis is a chronic inflammatory bowel disease in which free radicals play an important role in its pathogenesis. It is supposed that diet enriched with Omega 3 fatty acid and antioxidant compounds can be effective in the treatment of this disease. Grape seed extract contains potent antioxidant compounds. The aim of the present study was to evaluate possible useful effects of fish oil and grape seed extract enriched diets on the reduction of colonic damage and inflammation in acetic acid induced colitis. Materials and Methods: In this experimental study 50 male adult Wistar rats were randomly divided into five groups (n=10). Fish oil group (F group) received 1.6 ml fish oil, grape seed group (G group) received 50 mg/kg grape seed extract and fish oil + grape seed group (FG group) received 1.6 ml fish oil + 50 mg/kg grape seed extract orally for 1 month. Rats in control group (C group) and colitis group (Co group) received distilled water. After 1 month colitis induced in groups with intrarectal administration of 1ml acetic acid (4%) to induce ulcerative colitis. The control group received intrarectal saline. Two days after the induction of colitis the degree of tissue injuries and inflammation were assessed by macroscopical and histopathological scores of colonic mucosa. Results: Acetic acid administration induced ulcers, inflammation and severe crypts damages in mucosal tissue of the colon. The rats with colitis in the FG group showed significantly less macroscopic, microscopic damages and inflammation in colonic tissues compared with those in colitis group. However treatment with grape seed extract and fish oil did not result in any significant improvements in macroscopic and microscopic scores. Conclusion: The result of this study showed that fish oil and grape seed extract enriched diets before colitis induction play a protecting role against damages due to acetic acid induced colitis.

Abstract

Background and Objective: Hypoxia is one of the most common clinical stresses that occur during pregnancy, which has adverse effects on fetal development. Fish oil, with its antioxidant properties, prevents fetal disorders during pregnancy. This study was conducted to determine the effects of fish oil on apparent congenital abnormalities and fetal dimensions caused by hypoxia during gestation in rats.
Methods: In this experimental study, 36 female pregnant Wistar rats were divided into 6 groups of control, hypoxia, fish oil 0.5 ml, fish oil 1 ml, hypoxia+fish oil 0.5 ml, and hypoxia + fish oil 1 ml. Fish oil was administered by gavage, and the hypoxia model was established between 6 and 15 days of gestation by 3 hours of daily exposure to 10% oxygen and 90% nitrogen. On the 20th day of pregnancy, the embryos were removed from the uterus. First, the number of obtained embryos from each group was counted. Then, in terms of apparent abnormalities, the number of live fetuses and fetal resorption was evaluated. Finally, the length and weight of the fetuses were measured.
Results: The frequency of embryos with apparent abnormalities in the hypoxia and control groups was 18.18% and nil, respectively. The frequency of fetal resorptions in the hypoxia and control groups was 27.27% and 1.92%, respectively. Moreover, fetal weight and length were significantly reduced in the hypoxia group compared with the control group (P<0.05). However, the average weight and length of fetuses in the hypoxia groups receiving fish oil showed a significant increase compared to the hypoxia group (P<0.05).
Conclusion: Hypoxia during pregnancy in rats reduces fetal body dimensions and increases fetal abnormalities. However, fish oil can reduce the harmful effects of hypoxia on apparent congenital abnormalities and fetal body dimensions during pregnancy.
