In the presence of Dragon's Blood, the actionpotential amplitude of the bullfrog sciatic nerve was decreased, the conduction velocity was slowered and the refractory period was delayed.
牛蛙坐骨神经滴加龙血竭后，神经干动作电位幅值明显下降，不应期延长，传导速度减慢。

In the acute isolated bullfrog sciatic nerve, the amplitude, conductivity and refractory period of the actionpotential were also observed respectively after administration.
并在急性分离的牛蛙坐骨神经干上，观察龙血竭对坐骨神经动作电位幅值、不应期和传导速度的影响。
