Abstract:

Oxidative and inflammatory processes are elicited during hepatic post-ischemic reperfusion and generate liver damage. This study investigated the early anti-inflammatory effect of trans-resveratrol (T-res) and its consequences on the late self-aggravating inflammatory process in liver ischemia-reperfusion (I/R). Partial hepatic ischemia was initiated in rats for 1 h and T-res (0.02 and 0.2 mg/kg) was administered intravenously 5 min before starting reperfusion for 3 h. Plasma levels of aminotransferases and cytokines (tumour necrosis factor (TNF)-alpha, interleukin (IL)-1beta, IL-6) and hepatic neutrophil recruitment were assessed. Hepatic expression of stress protein (heat-shock protein (HSP-70), heme oxygenase-1(HO-1)) and cytokine (TNF-alpha, IL-1beta, keratinocyte chemoattractant (KC)) mRNA was investigated. I/R caused an increase in aminotransferase levels and increased polymorphonuclear cell infiltration. Post-ischemic treatment with T-res (0.02 and 0.2 mg/kg) resulted in a significant decrease in aminotransferase, IL-1beta and IL-6 plasma levels by about 40%, 60% and 40%, respectively, compared to the vehicle I/R group. Post-ischemic treatment with T-res (0.02 mg/kg) also significantly decreased hepatic neutrophil recruitment. TNF-alpha, IL-1beta, KC and HO-1 hepatic mRNA expression was reduced by T-res without any change in HSP-70 mRNA. This T-res mediated decrease in early release of cytokines and neutrophil recruitment led to a reduction in the late inflammatory process. T-resveratrol might be useful in the prevention of inflammation secondary to hepatic surgery or liver transplantation.
