Abstract

Objective uncontrolled ingestion of alcohol has dramatic consequences on the entire organism also associated with the oxidation process induced by alcohol by elevating radical oxygen species (ROS). Resveratrol, a non-flavonoid phenol, shows well-documented antioxidant properties. We investigated the potential antioxidant ability of this natural compound in a mouse model of alcohol addiction. Methods we administered (per os) for two months 10 mg/kg/day of resveratrol in alcoholic adult male mice. Oxidative stress was evaluated by measuring serum free oxygen radicals defense (FORD) and free oxygen radicals (FORT) levels. Resveratrol metabolites were measured in the serum of mice administered with resveratrol. Finally, the effect of resveratrol on alcohol-induced alteration of BDNF in the liver was investigated. Results prolonged consumption of resveratrol strongly counteracts serum ROS formation caused by chronic alcohol intake, without effects on natural, free oxygen radical defense. The presence of resveratrol metabolites only in the serum of animals supplemented with resveratrol potentiates the evidence that the antioxidant effect observed is due to the ingestion of the natural compound. Moreover, resveratrol supplementation can counteract alcohol-induced BDNF elevation in the liver, the main target of organ alcohol-induced damage. Conclusion the consumption of resveratrol through metabolite formation may play a protective role, by decreasing free radical formation, and by modulating BDNF involved in hepatic disruption induced by chronic alcohol consumption. Further investigation about the mechanism underlying the protective effect could reinforce the potential use of resveratrol as a dietary supplement to prevent damage associated with chronic alcohol abuse.
