Effect of Kineret® on ovarian ischemia reperfusion injury in a rat model

Aim: To investigate the effect of Kineret® on ischemia reperfusion (IR) injury in rat ovaries. Methods: Rats were divided into four groups: ovarian IR (IRG); 50 mg/kg Kineret® + ovarian IR (KIR-50); 100 mg/kg Kineret® + ovarian IR (KIR-100); and sham operation (SOC). KIR-50 (n = 10) and KIR-100 (n = 10) groups received an intraperitoneal injection of Kineret® at doses of 50 and 100 mg/kg, respectively. IRG and SOC (n = 10) rat groups were given distilled water as solvent using the same method. The results were compared between the groups. Results: In rats in which IR occurred, oxidant parameters, such as malondialdehyde (MDA) and myeloperoxidase (MPO), were increased, the level of proinflammatory interleukin 1 beta (IL-1β) was elevated and total glutathione (tGSH) as an antioxidant was decreased in the ovarian tissues. Administration of Kineret® at a dose of 100 mg/kg inhibited the increase of MDA, MOP and IL-1β and a decrease in tGSH caused by IR more significantly than administration of Kineret® at a dose of 50 mg/kg. In addition, 100 mg/kg Kineret® significantly decreased severe hemorrhage, degeneration and inflammatory signs in the follicular cells, caused by IR. Kineret® at 100 mg/kg markedly ameliorated increased apoptosis in ovarian tissue with IR more significantly than 50 mg/kg kineret. Conclusion: Our findings indicate that Kineret® might be useful in clinical practice for the treatment of damage that may occur as a result of ovarian torsion.
