Objectives : BHT has been commonly used to treatment of brain disorders in Oriental clinic in Korea. The purpose of this study was to determine the inhibitory effect of modified BHT-C extract on the transient forcal cerebral ischemia in rats. Method : We prepared ischemic rats by the transient middle cerebral artery occlution(MCAO; 90 min occlusion and 144 h reperfusion) in rat brains. BHT-C extract (100 and 200 mg/kg, i.p.) was administered every day after the onset of MCAO until 6 day. Result : BHT-C extract increased survival rate of ischemic rats compared with vehicle-treated rats. BHT-C extract treated rats (100 and 200 mg/kg) were shown a significant reduction in infarct volume compared with vehicle-treated rats. Conclusions : These results suggest that BHT-C extract may contribute to its protective effects in brain ischemia through the reduction of brain infarction.
