The article studied the protective effects of sinomenine (Sin) on nerve dysfunction, cerebral edema and the range of cerebral infarction after focal brain ischemia-reperfusion injury in rats, by using experimental model of reversible middle cerebral artery occlusion without craniectomy. The results showed that in the condition of 2h brain ischemia + 4h reperfusion the range of cerebral infarction was 29. 6 5. 3%, the water content of the brain tissue was 83. 05 0. 54 %, and obvious nerve dysfunction occurred. On condition that sinomenine was injected peritoneally 10 min before the occlusion of coddle cerebral artery at the doses of 30 and 60mg/kg, the extent of behavior disorder, cerebral edema and the range of cerebral infarction were obviously reduced. The present study indicates that sinomenine possesses a protective action on focal brain ischemia-reperfusion injury in rats.
