我们在同位素示踪法探讨卢痛宁、川芎嗪对心肌营养性血流量影响的基础上,又探讨了不同剂量的川芎、毕拔对小鼠冠脉血流量的作用,实验结果如下。一、实验材料和方法 1.86RbCl(氯化86铷):为无色透明液体,纯度:>99.9％。由北京原子能研究所供应。半衰期为19.5天,r射线能量为1.077(8.8％)Mev。用时以生理盐水稀释成0.06-0.15微居里/0.1毫升。 2.动物:体重21-24克雄雌性小鼠,由学院动物室供给。实验时按药物组和不同体重组随机分配。 3.制剂和药物:①川芎、毕拨制剂:由本室用水醇法提取,含量均为2克/毫
In the isotope tracer method, we investigated the effects of Lutongning and Ligustrazine on myocardial nutrient blood flow, and investigated the effects of different doses of Chuanxiong and Biqi on coronary blood flow in mice. The experimental results are as follows. First, experimental materials and methods 1.86RbCl (chlorinated 86铷): colorless transparent liquid, purity: >99.9%. It is supplied by the Beijing Atomic Energy Institute. The half-life is 19.5 days and the r-ray energy is 1.077 (8.8%) Mev. When used, it was diluted with physiological saline to 0.06-0.15 microcurie/0.1 ml. 2. Animals: Male and female mice weighing 21-24 grams were supplied by the College Animal Room. The experiment was randomly assigned according to drug groups and different body reorganizations. 3. Preparations and drugs: 1 Chuanxiong, dialectic preparations: from the room with water alcohol extraction, the content is 2 grams / milli
