RESUMEN
@#Objective To observe the effect of morroniside on cerebral infarction volume in focal cerebral ischemia-reperfusion rat model.Methods The animal model was induced by occlusion of middle cerebral artery with suture embolus, ischemia for 30 minutes, and reperfusion for 7 days. The infarction volume was measured by 2,3,5-triphenyltetrazolium chloride(TTC) staining technique.Results Compared with sham operation group, the cerebral infarction volume ratios increased obviously in model group and in the drug-treated（90 mg/kg，270 mg/kg）groups. Compared with model group, the cerebral infarction volume ratios decreased obviously in the morroniside-treated（90 mg/kg，270 mg/kg）group,while the cerebral infarction volume ratios in vitamin E-treated（35 mg/kg）group didn't change.Conclusion Morroniside may decrease the cerebral infarction volume after cerebral ischemia-reperfusion. It possesses protective effect against cerebral ischemia-reperfusion injury.
