The standardized Ginkgo extract, EGb761, has been reported to protect neurons against oxidative stress, but the underlying mechanisms are not fully understood. Methods—To characterize the oral consumption of EGb761 in transient ischemia, we performed the middle cerebral artery occlusion (MCAO) filament model in wild-type and heme oxygenase 1 (HO-1) knockouts. Mice were pretreated for 7 days before the transient occlusion or posttreated acutely during reperfusion; then neurobehavioral scores and infarct volumes were assessed. Furth
