针刺治疗急性脑缺血的微血管机制研究(Ⅰ)──针刺对急性脑缺血模型鼠微血管自律运动等的影响

Study of Acute Cerebral Ischemia Treated with Acupuncture (Ⅰ)──Influence of Acupuncture on vasomotion of MCA Model Rats

本研究以热阻凝法阻断大鼠大脑中动脉（MCA）造成急性局灶性脑缺血模型，采用激光多普勒血流仪动态检测了脑表面缺血区微血管的自律运动振幅和频率，及局部脑血流量、速率、单位体积内运动的血细胞数，从微血管角度深入探讨了急性脑缺血发生发展的病理机制和针刺治疗机理。

The middle cerebral artery (MCA) was occluded with thermocoagulation for preparing the model of local cerebral ischemia in rats, the cerebral vasomotive frequency (VF), vibration amplitude (VA),blood flow volume (BV), speed rate(SR) and blood cell quantity in motion (BCQ) were measured, in order to explore the mechanism of acute cerebral ischemia and acupuncture treatment in micro-vessel aspect.
