Objective: We aimed to evaluate the effectiveness of sugammadex on renal tissue for against ischemia-reperfusion injury. Methods: Twenty-one Wistar albino strain female rats were divided into three groups. The first group functioned as the control cohort for comparison. In Groups 2 and 3, a renal ischemia-reperfusion model was established. Moreover, following the cessation of ischemia, the rats in Group 3 were intravenously administered sugammadex at a dose of 4 mg kg-1. Blood and tissue samples were subsequently collected for analysis. Results: Biochemical analyses revealed a notable increase in the enzymatic activities of glutathione peroxidase and superoxide dismutase in Group 3 relative to Group 2 (P < 0.001 and P=0.015, respectively). Additionally, the concentration of malondialdehyde was found to be significantly reduced in Group 3 relative to Group 2 (P=0.004). Group 3 exhibited a substantial decrease in tumor necrosis factor-alpha, interleukin 6, and interleukin 1 beta levels when compared to Group 2 (P=0.021, P=0.006, and P=0.016 respectively). Group 2 exhibited the highest concentrations of neutrophil gelatinase-associated lipocalin and kidney injury molecule-1 (P < 0.001 and P=0.015, respectively). Similarly, the histopathologic tissue damage was the most prominent in Group 2 (P < 0.001). Conclusion: Sugammadex plays a protective role against ischaemia-reperfusion injury in renal tissue.

Background: The aim of this study was to analyze the effect of sugammadex on ischemia-reperfusion injury in corporal tissue. Methods: Eighteen male Wistar Albino strain rats were divided into three groups. Group 1 served as the control group. A priapism model was induced in rats in Group 2 and 3. Rats in Group 3 were additionally administered 4 mg/kg sugammadex intravenously immediately after reperfusion. All rats underwent penectomy for histopathological and biochemical evaluations, and blood samples were collected. Results: In Group 2, total oxidant status (TOS) and malondialdehyde (MDA) levels were significantly higher compared to other groups (p < 0.001 and p = 0.009, respectively). A substantial reduction in both TOS and MDA levels was found in Group 3 (p <0.001 and p = 0.043, respectively). Group 2 exhibited significantly lower activities of a glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) compared to Group 1 (p = 0.043 and p = 0.024, respectively). In contrast, Group 3 showed significant increases in both antioxidant enzyme activities (p = 0.036 and p = 0.034, respectively). Similarly, the total antioxidant status (TAS) was dramatically higher in Group 3 compared to Group 2 (p < 0.001). Microscopic examinations revealed improvements in vasocongestion, edema, desquamation and inflammation scores in Group 3 compared to Group 2 (p < 0.001). Conclusions: Biochemical and histopathological findings suggest that, sugammadex significantly mitigates oxidative damage parameters in corporal tissue affected by ischemia-reperfusion injury.
