OBJECTIVE To explore the protective effects of Buyang Huanwu decoction(BYHWD) combined with edaravone(ED) on cerebral ischemia-reperfusion injury in mice. METHODS The middle cerebral artery occlusion/reperfusion model was established by the improved intraluminal filament technique in mice. The mice were randomly divided into sham operation group, model group, BYHWD group, ED group, BYHWD+ED group. The differences of neurologic impairment score were observe on 1st, 3rd and 7th day.
