Renal injury occurring as a result of renal ischemia-reperfusion may lead to renal failure or even death. The aim of this study is to investigate possible protective effects of Gossypin on tissue damage occurred due to ischemia-reperfusion in rat kidney tissue. A total of 48 male Wistar albino rats were used in the study. These rats were randomly divided into 6 groups equally (n = 8). The created groups were control (C), sham (S), ischemia-reperfusion (I/R), I/R + DMSO, I/R + 400 mu g/kg gossypin and I/R + 4 mg/kg gossypin. In the rats of sham group, the right nephrectomy was performed. In the rats of other groups rather than sham, the left renal artery was clamped after performing the right nephrectomy. Gossypin was administered intraperitoneally before the reperfusion. 24 h reperfusion was applied to the left renal after 1 h of ischemia. TNF-alpha, IL-1 beta, IL-6 and IL-10 levels were measured with spectrophotometric methods in the kidney tissues after the procedures were completed. Apoptosis and inflammatory pathways were evaluated histopathologically using Caspase 3 and NF-kappa B antibodies. There was a statistically significant decrease in IL-1 beta and IL-6 levels of the gossypin groups compared to the I/R group (P<0.05). As the level of TNF-alpha was decreased in the gossypin administered groups compared to the I/R group although not statistically significant, the level of IL-10 was increased. In the present study, we aimed to show that gossypin in renal I/R model is effective on inflammatory process and apoptosis and that it can be used in routine treatment to decrease the damage in all reasons that may cause I/R. In addition, this study can shed light on the studies to be done in this field in the future.
