RESUMO

【Objective】To observe the effects of bamboo leaf extract(BLE)on cerebral ischemia.【Methods】 Effect of BLE(at the concentrations of 10,20 and 40 mg/kg respectively,iv)on rabbit carotid thrombus induced by cotton thread was observed.Meanwhile,the effects of BLE(at the concentrations of 15,30 and 60 mg/kg respectively,iv)on neurological deficit and cerebral infarct size in rats with middle cerebral arterial obstruction(MCAO),as well as the effects of BLE(at the concentrations of 22.5,45,and 90?mg/kg respectively,iv)on mice stroke index,grasping time of decapitated mice and survival time of mice subjecting to bilateral carotid ligation were also observed.【Results】BLE inhibited rabbit carotid thrombosis,improved neurological deficit and reduced cerebral infarct size in MCAO rats(P

RESUMO

OBJECTIVE:To evaluate the antihypoxic effect of orientoside on hypoxia model rats.METHODS:The hy-poxia rats model was established through normobaric hypoxia,poisoning with sodium nitrite,potassium cyanide and lidocaine,trachea occlusion,decapitation,etc.20minutes prior to the modeling,the rats were administered with the corresponding drugs with the anti-hypoxic effects observed.RESULTS:As compared with placebo group,the survival time of rats under nor-mobaric hypoxia,poisoned by sodium nitrite,potassium cyanide and lidocaine,and the electrocardiograph extinction time after trachea occlusion and the gasping time of mice after decapitation were all significantly prolonged by orientoside.CONCLU-SION:Orientoside has antihypoxic effect on hypoxia model rats.
