Aim: The aim of the study was to investigate the effectiveness of zofenopril in an experimental model of ovarian torsion in rats with histologic and biochemical assessments.
Material and methods: Experimental procedures were performed on 35 female rats (Wistar albino). Rats were randomly divided into five groups as: sham (sham operated, n = 7); vehicle group 1 (torsion-detorsion, n = 7) with 2 h ischemia and 2 h reperfusion; vehicle group 2 (torsion-detorsion, n = 7) with 2 h ischemia and 5 days' reperfusion; zofenopril group 1 (torsion-detorsion, n = 7) with 2 h ischemia, 2 h reperfusion and a signal dose of oral 15 mg/kg zofenopril; and zofenopril group 2 (torsion-detorsion, n = 7) with 2 h ischemia, 5 days' reperfusion and 5 days' oral 15 mg/kg zofenopril. A scoring of histopathologic evaluation was performed on the ovaries according to congestion, bleeding, edema, and cellular degeneration. Biochemical assessments included catalase, tissue malondialdehyde and protein carbonyl.
Results: Compared with the vehicle groups, histopathologic scores, tissue malondialdehyde and protein carbonyl levels, which reflect oxidative stress markers, were significantly lower in the zofenopril groups. Furthermore, catalase levels were significantly increased in the zofenopril group.
Conclusion: Our study results revealed that zofenopril attenuates injury induced by ischemia-reperfusion on rat ovary.
