临床及动物实验均证实八厘麻毒素能明显降低血压和降慢心律。本文报告其药理机理的动物实验研究结果。 一、方法与结果 狗以硫喷妥钠麻醉。将塑科管插入股动脉,并与水银检压计连接,记录血压的变化。以心电图机记录心率和心律。实验药物均经输液塑料管注入股 Both clinical and animal experiments confirm that mariidotoxin can significantly reduce blood pressure and slow heart rate. This article reports the results of animal experiments on its pharmacological mechanism. I. Methods and results Dogs were anesthetized with thiopental. The plastic tube was inserted into the femoral artery and connected to a mercury pressure gauge to record changes in blood pressure. Heart rate and rhythm are recorded on an electrocardiograph. The experimental drugs were injected into the plastic tube via infusion
