AIM: To investigate the effect of fisetin on learning memorial ability deficit after cerebral ischemia reperfusion and its possible mechanism. METHODS: Adult male Wistar rats were randomly divided into seven groups: the sham operation,the IR model group,fisetin group( 10,20,40mg/kg,p. o.). The four-vessel occlusion method was used to build rat model of cerebral ischemia reperfusion. All rats were tested for Morris water maze( MWM). The serum level of corticosterone was detected using the enzyme linked immun...
