N2 - Introduction: Ovarian torsion is a serious gynaecologic problem in gynecologic oncology where conservative management includes detorsion of the involved segments. Torsion has been implicated in ovarian damage and loss of fertility, and detorsion in one of the most important factors in further injury. Ovarian injury resulting from torsion/detorsion resembles that caused by ischemia/reperfusion (I/R) injury observed in other organs. Aim: In this experimental study, the aim is to examine the effects of Vitamin C and selenium on ischemia-reperfusion injury in the rat ovary. Materials and Methods: In this study 48 female Wistar rats were used. In the Sham group(Group 1) only laparotomy was performed. In group 2 (ischemia) ovarian ischemia was produced and the right ovary was surgically removed 4 h later. In group 3(ischemia/reperfusion ) an ischemic period of 4 h was followed by reperfusion for 1 h, the right ovary was removed. In groups 4,5 and 6, after 4h of ischemia, either vit C, selenium, selenium+vit C respectively were infused before reperfusion; after 1 h of reperfusion the right ovary was removed. The ovaries were examined by histopathologic evaluation. Results: There was no cell injury in the Sham group but we determined significant difference in the group of Vit C and selenium infused together. In the ischemia group we determined cell injury was less than ischemia/reperfusion group. The groups that have been infused Vit C and selenium respectively, were similar with ischemia group, but less than ischemia/reperfusion group. Conclusion: We concluded that Vit C and selenium are effective in decreasing ischemia/reperfusion injury CR - 1. Hibbard L. (1985) Adneksiyal torsion. Am. J. Obstet. Gynecol.1985; 152, 456-461.
