Abstract
Background: In this study, we aimed to investigate the effects of cilostazol and levosimendan, and the combination of these agents on the lung remote organ damage after ischemia/reperfusion (I/R) following abdominal aortic surgery. Methods: The experiments were performed on 35 male Wistar albino rats weighing mean 219±26 g. The rats were randomly assigned into five groups, including each of seven rats. Rats were pretreated with cilostazol and levosimendan, alone or in combination, and then lower extremities were subjected to I/R induced by a infrarenal aortic occlusion for duration of 120 minutes, followed by a-60 minute- reperfusion. The rats were sacrificed under deep anesthesia and the lung tissues were removed. Malondialdehyde (MDA) levels, superoxide dismutase (SOD) activity, and glutathione (GSH) levels were measured in the lung tissues. The tissue samples were further examined histopathologically under light microscopy. Results: It was found that I/R elevated MDA levels accompanied by a reduction in SOD activities and GSH levels (p
