Resveratrol prevents global cerebral ischemia-induced decrease in lipid content.

OBJECTIVE: The present study was undertaken to evaluate whether resveratrol (RSV) modulates membrane lipid composition, as well as on ganglioside profile in ischemia/reperfusion injury. METHODS: Global cerebral ischemia was induced by four-vessel occlusion for 10 minutes. RSV (30 mg/kg) or vehicle was intraperitoneally administered to rats 7 days prior to ischemia. Brain structures were homogenized with chloroform/methanol for ganglioside, phospholipids, and cholesterol levels. RESULTS: RSV significantly prevented the reduction in the total content of gangliosides, phospholipids, and cholesterol in hippocampi and cerebral cortex induced by global cerebral ischemia. Although ischemia/reperfusion decreased ganglioside content, the ganglioside profiles were apparently not modified. CONCLUSIONS: Our experiments suggest that lipid metabolism is important for development of ischemic damage and indicate that RSV treatment 7 days prior to ischemia may prevent membrane lipid loss.
