本实验观察了补阳还五汤注射剂对家兔脑血管的扩张作用。实验方法实验共用家兔22只,体重2.5kg左右。家兔以3%戊巴比妥纳1ml/kg静脉麻醉。其中11只先描绘其脑电阻图、前肢电阻图和心电图,并由心腔抽血检查红细胞比积和纤维蛋白原含量,然后静脉注射补阳还五汤注射剂(剂量为1.5ml/kg)。以每分钟约1ml之速度静脉注射,注射后5、10、15、20、25、30分钟记录脑电阻图、肢体电阻图及心电图,注射后30分
This experiment observed the effect of Buyang Huanwu Decoction injection on the expansion of cerebral blood vessels in rabbits. Experimental Methods Twenty-two rabbits were used in experiments, weighing about 2.5kg. Rabbits were intravenously anesthetized with 3% pentobarbital 1 ml/kg. Eleven of them first described the brain resistance map, forelimb resistance map, and electrocardiogram, and blood volume from the heart chamber was used to check the hematocrit and fibrinogen levels, and then intravenous injection of Buyang Huanwu Decoction (a dose of 1.5 ml/kg). Intravenous injection was performed at a rate of about 1 ml per minute, and brain resistance maps, limb resistance maps, and electrocardiograms were recorded at 5, 10, 15, 20, 25, and 30 minutes after injection, and 30 minutes after injection.
