Protective effects of resveratrol on spleen and ileum in rats subjected to ischemia-reperfusion

Abstract

Resveratrol is as an antioxidant with free radical-scavenging activity and finds its clinical application in the prevention of postischemic tissue injury following solid organ transplantation. This study investigates the effect of Resveratrol on spleen and ileum tissues subjected to hepatic ischemia-reperfusion (I/R) in rats. Twenty-four rats were recruited in the study as follows: group A: I/R (n = 8), group B: I/R + Resveratrol (n = 8), and group C: sham operation (n = 8). After intraperitonealy pretreatment of eight rats with resveratrol (15 mg/kg/d) for 5 days, 16 rats were subjected to 45 minutes of hepatic ischemia followed by 30 minutes reperfusion period. Resveratrol was given 15 minutes prior to ischemia and just before the reperfusion in rats. After reperfusion period all rats were sacrificed. Spleen and ileum tissues were examined spectrophotometrically to measure malondialdehyde (MDA), glutathione (GSH), and total nitrite, nitrate as an end product of nitric oxide (NO) levels. Concerning the spleen, statistically significant decrease of GSH and increase of MDA and NO levels were found group A when compared to groups B and C (P = .040, P = .004, and P = .001 group A vs group B; P = .05, P = .003, and P = .001 group A vs group C, respectively). Parallel results were obtained in ileum. A statistically significant decrease in GSH and an increase in MDA and NO levels in group A in respect to group B and group C was obtained (P = .048, P = .034, and P = .001 group A vs group B; P = .004, P = .001, and P = .003 group A vs group C, respectively). The result of this study shows that resveratrol has a protective effect on spleen and ileal mitochondrial oxidative stress in rats subjected to I/R.
