腐婢(俗名),民间用于疔疮、蛇咬后的止痛消肿。本文观察了它对蟾蜍离体坐骨神经动作电位的影响并与普鲁卡因作用相比较。材料与方法一、材料 1.药物:干燥腐婢茎叶切碎,水煎加95％乙醇得乙醇液,静置,取滤液水浴蒸发乙醇,得浓缩液(每ml含生药2g)。 2.动物:用大小近似蟾蜍制备坐骨神经标本。 3.仪器:SBR-1二线示波器,DCQ-2型电子刺激器,神经标本盒等。二、方法将上述仪器用屏蔽线按常规刺激线路方框图连接,按电子刺激器刺激神经。刺激参数:频率100Hz,延迟1ms,波宽2ms,输出电压0.48V。先引导出用药前的动作电位,然后将药液滴在刺激电极与引导电极之间。每隔5分钟刺激1次,检查动作电位的变 Corruption (common name), folk used for hemorrhoids, snake bites after swelling and swelling. This article has observed its effect on the action potential of isolated sciatic nerves of iliac crest and compared with that of procaine. Materials and Methods 1. Materials 1. Drugs: dried and rotted stems and leaves were chopped and decocted with 95% ethanol to obtain ethanol. After standing, the filtrate was taken to evaporate ethanol to obtain a concentrated solution (containing 2 g crude drug per ml). 2. Animals: Preparation of sciatic nerve specimens with similar size. 3. Instruments: SBR-1 2-wire oscilloscope, DCQ-2 electronic stimulator, and nerve specimen box. Second, the method of the above equipment with a shielded line connected to the conventional stimulation circuit block diagram, according to the electronic stimulator to stimulate the nerve. Stimulation parameters: frequency 100Hz, delay 1ms, wave width 2ms, output voltage 0.48V. The action potential before the medication is first guided, and then the drug is dropped between the stimulating electrode and the guiding electrode. Stimulate once every 5 minutes to check the change of action potential
