扎冲注射液系由蒙医经典方剂“扎冲朱苏木”研制而成。1980年曾试用于临床,在治疗脑血管病偏瘫37例中32例有效,其中16例显效。为探索其作用机制,进行了有关动物实验,现报导如下:实验方法与结果Ⅰ、毒性实验一、半数致死量:用上下法(序贯法)。10只19—22克重健康小白鼠(雌雄不分)尾静脉注射,结果:LD_(50)=14ml/kg。二、局部刺激试验:取体重2公斤左右的健康家兔2只,用股四头肌法,缓缓注入扎冲注射液1ml,另一侧用同法注射生理盐水1ml,给药后24小时,48小时各处死解剖一只,肉眼检查,股四头肌无明显充血现象。三、溶血试验:取干燥清洁试管6只,依序加入家兔红血球混悬液、生理盐水及扎冲注射液。混匀后37℃恒温箱中静 Zhachong injection liquid was developed by the Mongolian medical classic prescription “Zhachong Zhusu”. In 1980, it was tested in clinical practice. Among the 37 cases of hemiplegia treated with cerebrovascular disease, 32 cases were effective, of which 16 cases were markedly effective. In order to explore its mechanism of action, related animal experiments were conducted and are reported as follows: Experimental methods and results I. Toxicity experiments I. Half-life lethal doses: Using the top-down method (sequential method). Ten 19-22 healthy mice (not divided equally) were injected through the tail vein. Results: LD 50 = 14 ml/kg. Second, local irritation test: Take two healthy rabbits weighing about 2 kilograms, using the quadriceps method, slowly inject 1ml of Zha Chong injection, the other side with the same method of injection of normal saline 1ml, 24 hours after administration , 48 hours anatomy of a dead, naked eye examination, no significant congestion of the quadriceps. 3. Hemolysis test: Take 6 dry and clean test tubes, and then add rabbit erythrocyte suspension, physiological saline and Zhachong injection sequentially. After mixing 37 °C incubator static
