微血管管径变化除与本身的自律运动有关外,往往是微循环障碍的重要标志.本研究采用自己研制的测管径闭路电视系统研究山莨菪碱(654)对微血管收缩的拮抗作用.30只叙利亚种金黄地鼠,雄性,体重70～120 g,经戎巴比妥钠30 mg/kg麻醉后,在恒温灌流维持下,测量频囊的微动脉.第一组实验结果表明,腹腔注射0.1％去甲肾上腺素(NA)0.2 ml后,>36μm的微动脉管径变化不大,P>0.5;而 In addition to its own autonomic movement, the change of microvessel diameter is often an important sign of microcirculation disturbance.In this study, self-developed caliber CCTV system was used to study the antagonism of anisodamine (654) on microvascular contraction.30 Syrian golden hamster, male, weighing 70-120 g, was anesthetized with Rongbituo 30 mg / kg, and the arterial microvasculature of the capsule was measured under the maintenance of isothermal perfusion. The first group of experiments showed that intraperitoneal injection of 0.1 % Of norepinephrine (NA) 0.2 ml, microarray diameter> 36μm little change, P> 0.5; and
