Abstract
Objective: The aim of this study is to investigate the anti-inflammatory and anti-apoptotic effects of ascorbic acid (AA) and sodium selenite (SS) administration in renal ischemia and reperfusion (IR) injury. Materials and Methods: Twenty-eight Wistar-albino rats were divided into four groups. Group I; Control group, Group II; IR group, Group III; IR+0.25mg/kg SS and 100mg/kg AA and Group IV; IR+0.50mg/kg SS and 200mg/kg AA. In the control group, only surgical stress was created. In the IR group, 60 minutes of ischemia and 24 hours of reperfusion were applied in the left kidney after right nephrectomy. SS and AA were administered to Groups III and IV at doses determined 5 days before the IR procedure. Results: In comparison of Group II with Group I, Group III and Group IV; severe damage was observed in the morphological structures of the glomerulus and renal tubules in Group II (p<0.05). Compared to Group I, Group III and Group IV the expression of TNF-α, IL-6, Caspase-3, and Bcl-2 and the percentage of positive cells increased statistically in Group II (p<0.001). Conclusion: This study determined that prophylactic administration of ascorbic acid and sodium selenite showed protective effects against acute kidney injury.
