ABSTRACT
PURPOSE: This study aimed to evaluate the protective effects of enoxaparin on ovarian tissue subjected to experimental ischemia/reperfusion (I/R) injury in rats.
METHODS: Thirty female rats were divided into three groups: control, ischemia/reperfusion (I/R), and ischemia/reperfusion plus enoxaparin (I/R+E). Ovarian I/R injury was induced by 1 hour of ischemia followed by 1 hour of reperfusion. Rats in the I/R+E group received subcutaneous enoxaparin (0.5 mg/kg) prior to ischemia. Histopathological injury was assessed using a standardized scoring system, and total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) were measured.
RESULTS: Histopathological injury scores were significantly higher in the I/R group compared with controls (p < 0.05), with no significant difference between the I/R and I/R+E groups (p > 0.05). Biochemical analysis showed significantly higher TAS and lower OSI levels in the I/R+E group compared with the I/R group (p < 0.05), while TOS levels were comparable between groups.
CONCLUSION: Although enoxaparin did not significantly improve histopathological injury, its beneficial effects on oxidative stress parameters suggest a protective role against oxidative stress in ovarian I/R injury.
