Objective: To examine the biochemical and histopathological effects of ischemia/reperfusion (I/R) injury in a ruptured abdominal aortic aneurysm (RAAA) model in rats, and to investigate the potential protective role of resveratrol. Methods: Thirty-two male Sprague-Dawley rats were randomly assigned into four groups-control, I/R, sham (I/R + solvent/dimethyl sulfoxide), and I/R + resveratrol. The control group underwent midline laparotomy only. In the other groups, infrarenal vascular clamps were attached following 60-min shock to the abdominal aorta. Ischemia was applied for 60 min followed by reperfusion for 120 min. In the I/R + resveratrol group, intraperitoneal 10 mg/kg resveratrol was administered 15 min prior to ischemia and immediately before reperfusion. The I/R + dimethyl sulfoxide group received dimethyl sulfoxide, and the I/R group was given saline solution. All animals were sacrificed by exsanguination from the carotid artery at the end of the experiment. In addition to histopathological examination of the rat kidney tissues, malondialdehyde, glutathione, catalase, and nitric oxide levels were also investigated. Results: A decrease in glutathione, catalase and nitric oxide levels, together with increases in malondialdehyde levels, numbers of apoptotic renal tubular cells, caspase-3 levels, and tubular necrosis scores, were observed in the IR and I/R + dimethyl sulfoxide groups. In contrast, resveratrol increased glutathione, catalase and nitric oxide levels in renal tissues exposed to I/R, while reducing malondialdehyde levels, apoptotic renal tubular cell numbers, caspase-3 levels, and tubular necrosis scores. Conclusion: Our findings suggest that resveratrol can be effective against I/R-related acute kidney damage developing during RAAA surgery by reducing oxidative stress and apoptosis.
