电针对狗脑血流量及脑软膜微循环血流量的影响

本文应用电磁流量计和激光多普勒微循环血流计，观察了电针足三里和曲池穴对正常狗脑血流量和脑软膜微循环的影响。结果表明：电针1分钟及停针后20、30、60和90分时脑血流量均显著增加，脑血管阻力下降，表现为即时效应和后继效应。同时脑软膜微循环血流量在电针1、5和10分及停针后30分时均显著增加。结果提示，针刺治疗缺血性脑血管疾病机理之一可通过增加脑血流量、改善脑微循环，从而加快缺血脑组织的恢复。

Effects of Electrical Acupuncture on the Cerebral Blood Flow and the Pial Microcirculatory Blood Flow in Dogs

Using electromagnetic flowmeter and Laser Coppler Microcirculatory flowmeter, we studied the effect of electrical acupuncture at Zusanli (ST 36) and Quchi (LI 11) on cerebral blood flow and pial microcirculatory blood flow in dogs. The results showed that the cerebral blood flow increased remarkably, while the cerebral vascular resistance (CUR) decreased 1 min. after the acupuncture start and 20, 30, 60, 90 min. after stopping of the stimulation, and the blood flow of the pial microvessels increased 1, 5, 10 min. after starting of acupuncture and 30 min. after stopping of the stimulation. It indicates that one of the mechanisms of treatment of cerebral vascular diseases with acupuncture is that acupuncture increases the cerebral blood flow and improve the pial microcirculation.
