Abstract/OtherAbstract:
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.
