ABSTRACT
AIM To investigate the protective effect of sodium gamma-hydroxybutyrate (?-OH) against cerebral ischemia-reperfusion injury in gerbils and the neuroprotective mechanism of ?-OH. METHODS The occlusion of bilateral carotid arteries of gerbil was used to make the cerebral ischemia-reperfusion models. Different doses of ?-OH were administered intraperitoneally 40 min prior to the onset of ischemia. After 10 min ischemia and 1 h reperfusion, bilateral hippocampus, cortex and striatum were taken out to measure ATPase, SOD and MDA. RESULTS The contents of MDA markedly elevated while Na +,K +-ATPase, Ca 2+ -ATPase and SOD activities decreased in hippocampus, cortex and striatum 1 h after ischemia-reperfusion. ?-OH administered prior to ischemia can partly reverse the elevation of MDA contents and the reduction of SOD activities. ?-OH given after ischemia can still provide partly protective effect. CONCLUSION ?-OH provides significant protective effect against cerebral ischemia-reperfusion injury by protecting ATPase and SOD activities, deleting free radicals and reducing the lipid peroxidation.
