Abstract
Objective:
The aim of the present study is to investigate the efficiency of colchicine in the experimental rat ovarian torsion model in the light of histological and biochemical data.
Study Design:
A total of 35 Wistar albino female rats were randomly divided into 5 groups, group 1: (control-sham operated, n = 7); group 2: (torsion/detorsion, n = 7) 2 hours of ischemia and 2 hours of reperfusion; group 3: (torsion/detorsion, n = 7), 2 hours of ischemia and 5 days of reperfusion; group 4: (torsion/detorsion, n = 7) 2 hours of ischemia and 2 hours of reperfusion and a signal dose of oral 1 mL/kg colchicine; and group 5: (torsion/detorsion, n = 7), 2 hours of ischemia and 5 days of reperfusion and 5 days of oral 1 mg/kg colchicine. Histopathologic evaluation was performed by a scoring that assesses congestion, bleeding, edema, and cellular degeneration in the ovarian tissue. Catalase, tissue malondialdehyde (MDA), and protein carbonyl levels were calculated.
Results:
The histopathologic scores, MDA, and protein carbonyl levels in the control and colchicine groups were significantly lower than groups 2 and 3 (P < .001). Catalase activities were significantly higher in the control and colchicine groups than in groups 2 and 3 (P < .001). The results of the histopathologic parameters and biochemical markers showed that protective effects of colchicine treatment persisted up to 5 days.
Conclusion:
Our study results revealed that colchicine reduced ovarian ischemia–reperfusion injury in experimental rat ovarian torsion model. As the ovarian detorsion is the first choice of the treatment modality in the early phase, antioxidant and anti-inflammatory treatment modalities like colchicine might be used to reduce ovarian ischemia–reperfusion injury.
