Effects of resveratrol on blood homocysteine level, on homocysteine induced oxidative stress, apoptosis and cognitive dysfunctions in rats.

We aimed to examine the protective effects of resveratrol against homocysteine induced oxidative stress, apoptosis and cognitive impairment. Rats were randomly divided into three groups. Control group received standard rat food; homocysteine group (Hcy group) received daily methionine at a dose of 1g/kg-body weight dissolved in drinking water for thirty days; third group (Hcy+Res group) received same amount of methionine plus 20mg/kg/day resveratrol intraperitoneally for thirty days.
