黄芪注射液静脉注射对家兔正常血压有短暂的降压作用,重复注射未见快速耐受现象;不改变去甲肾上腺素的升压效应;当给麻醉家兔十二指肠内灌注黄芪注射液10毫升时,连续观察2小时,其血压和心电图无明显改变。对垂体后叶素所致急性心肌缺血性心电图ST段改变及对异丙基肾上腺素所致急性心肌坏死性肌酸磷酸激酶改变有明显的保护作用。该注射液毒性很低,在小鼠可承受的最大容量范围内,静注或腹腔注射皆无
Astragalus injection intravenously has a transient antihypertensive effect on normal blood pressure in rabbits. Repeated injections have no rapid tolerance; no change in noradrenaline’s boosting effect; when anesthetized rabbits are given intraduodenal infusion of astragalus injection When the liquid was 10 ml, continuous observation for 2 hours showed no significant change in blood pressure and electrocardiogram. It has a protective effect on ST segment changes of acute myocardial ischemic electrocardiogram induced by pituitrin and acute myocardial necrosis creatine phosphokinase induced by isoproterenol. The toxicity of the injection is very low. Within the maximum volume that the mouse can bear, there is no intravenous or intraperitoneal injection.
