目的：了解葛根素对椎基动脉供血不足的疗效。方法：将72例推基动脉供血不足病人随分成两组，治疗组用葛根素，对照组用尼莫通，通过观察推基动脉血流量及血液流变学的变化判其疗效。结果：葛根素对椎基动脉脑血流量的改善情况与对照组相仿（P＞0．05），但前者具有显的改善血液流变学作用（P＜0．01）。结论：葛根素有良好的改善椎基动脉供血不足作用。
Objective: To understand the effect of puerarin on vascular insufficiency of vertebral artery. METHODS: Seventy-two patients with push-based arterial insufficiency were divided into two groups: puerarin in the treatment group and nimotop in the control group. The curative effect was evaluated by observing changes in blood flow and hemorheology of the pusher artery. RESULTS: The improvement of cerebral blood flow of basal arterioles by puerarin was similar to that of the control group (P>0.05), but the former had significant improvement in hemorheology (P<0.01). Conclusion: Puerarin can improve the blood supply of vertebral artery.
