Protective effects of tempol in an experimental ovarian ischemia–reperfusion injury model in female Wistar albino rats

Abstract

The aim of this study was to investigate the antioxidant effects of tempol on ovarian ischemia–reperfusion (I/R) injury in rats. Forty female Wistar albino rats were randomly divided into 5 groups: Group I, sham; Group II, ischemia (I); Group III, I/R; Group IV, I/R + tempol 30 mg/kg i.p; Group V, I/R + tempol 50 mg/kg i.p. Oxidative stress index (OSI) was significantly higher in the ischemia group and the I/R group than in the sham group. Catalase levels were significantly lower in the I/R group than in the I/R + tempol 30 mg/kg i.p. and the I/R + tempol 50 mg/kg i.p. groups. Glutathione peroxidase levels were lower in the I/R group than in the I/R + tempol 30 mg/kg i.p. and the I/R + tempol 50 mg/kg i.p. groups. MDA levels were significantly lower in the I/R + tempol 30 mg/kg i.p. group and the I/R + tempol 50 mg/kg i.p. group than in the I/R group. The levels of the histopathological parameters were significantly decreased in the I/R + tempol 50 mg/kg i.p. group compared with the I/R group. Tempol can be used for reducing ovarian I/R injury.
