Abstract
Aim: The aim of this study was to investigate whether prophylactic treatment with edaravone prevents ischemia/reperfusion (I/R)-induced ovarian damage during pneumoperitoneum in an experimental rat model. Methods: Twenty-eight female Sprague Dawley rats were allocated randomly to 4 groups. The sham group (group 1) was only subjected to catheter insertion, not to pneumoperitoneum. Group 2 received a 1 mg/kg dose of 0.9% sodium chloride by the intraperitoneal route for 10 min before pneumoperitoneum. Groups 3 and 4 received 6 and 12 mg/kg edaravone, respectively, by the intraperitoneal route for 10 min before pneumoperitoneum. After 60 min of pneumoperitoneum, the gas was deflated. Immediately after the reperfusion period, both ovaries were excised for histological scoring, caspase-3 immunohistochemistry and biochemical evaluation including glutathione (GSH) and malondialdehyde (MDA) levels. Also, total antioxidant capacity (TAC) was measured in plasma samples to evaluate the antioxidant effect of edaravone. Results: Ovarian sections in the saline group revealed higher scores for follicular degeneration and edema (p < 0.0001) when compared with the sham group. Administration of different doses of edaravone in rats significantly prevented degenerative changes in the ovary (p < 0.0001). Caspase-3 expression was only detected in the ovarian surface epithelium in all groups, and there was a significant difference between the treatment groups and the saline group (p < 0.0001). Treatment of rats with edaravone reduced caspase-3 expression in a dose-dependent manner. Moreover, biochemical measurements of oxidative stress markers (MDA, GSH and TAC) revealed that prophylactic edaravone treatment attenuated oxidative stress induced by I/R injury. Conclusion: These results indicate that prophylactic treatment with edaravone prevents I/R-induced ovarian damage during pneumoperitoneum in an experimental rat model.
