针灸作为中国的一个有效治疗方法

已有两千多年的历史

历代和现今的文献中均有很多报导

在我们的临床研究工作中

观察到针刺治疗缺血性中风的有效率为87.5%和92.31%。但针刺为什么能治疗缺血性中风?其原理如何?这是应该探讨的问题。本文试图从针刺对实验性脑缺血动物的血液动力学

包括脑血流量和脑血管阻力的影响

来探讨针刺治疗缺血性中风的原理。The results in observation of 44 cats showed that the animal model of acute experimental cerebral ischemia were peroformed by ligating some cerebral supply artery.Acupuncture of cerebral ischemia cats at “Quchi”(曲池)and “Yanglingquan”(阳陵泉)may increase cerebral blood flow (CBF)and reduce cerebral blood vessel resistance (CVR).After removing the needle

CBF may increase last for 35 minutes

but the CVR reduced not prominently.In normal cats

the hemodynamics of the brain were not markedly affected by acupuncture.
