The study aimed to investigate the effect of extract of Ginkgo biloba (EGb) on the expression of vascular endothelial growth factor (VEGF) after subarachnoid hemorrhage (SAH). Wistar rats were divided into non-SAH, SAH, vehicle, EGb1 (low-dose), and EGb2 (high-dose) groups. VEGF mRNA and VEGF protein were measured from brain tissues. The expressions of VEGF mRNA in SAH and vehicle groups were enhanced 24 and 72 hr after the establishment of SAH. Increased VEGF positive cells were found in the brain tissues in SAH and vehicle groups. The expressions of VEGF mRNA and VEGF protein were further increased by the pretreatment of EGb. We concluded that EGb exerts protective effects on secondary cerebral ischemic injury after SAH via the promotion of the expression of VEGF.
