Objective To reveal the effects of montelukast as an antioxidant and tissue protective agent and study the biochemical and histopathologic changes in experimental ischemia and ischemia-reperfusion (I/R) injury in rat ovaries. Design Experimental study. Setting Experimental surgery laboratory in a university department. Animal(s) Forty-eight rats with experimentally induced ovarian torsion. Intervention(s) Group 1: sham; Group 2: ovarian ischemia; Group 3: a 30-hour period of ischemia followed by a 3-hour reperfusion. Groups 4 and 5: rats administered 10 and 20 mg/kg doses of montelukast before a half-hour of ischemia, then ovarian ischemia applied; after a 3-hour period of ischemia, the bilateral ovaries removed. Groups 6 and 7: 3-hour period of ovarian ischemia applied, then 2.5 hours after the ischemia induction, rats given montelukast. Group 8: sham operation and 20 mg/kg of montelukast; at the end of a 3-hour period of ischemia, 3-hours of reperfusion continued. Main Outcome Measure(s) Measurement of ovarian tissue concentrations of superoxide dismutase (SOD), glutathione (GSH), lipid peroxidation (LPO) and myeloperoxidase (MPO) activity; and histopathologic examination of all ovarian rat tissue. Result(s) Montelukast treatment normalized changes of LPO and MPO and stimulated an overproduction of endogenous SOD and GSH. The results of the histologic parameters showed that treatment with montelukast in the I/R group of rats ameliorated the development of ischemia and reperfusion tissue injury. Conclusion(s) Montelukast at different doses attenuates ovarian I/R-induced ovary tissue injury in rats.
