目的研究电刺激对坐骨神经干兴奋性的影响。
Objective To observe the effect of electric stimulation on the excitability of sciatic nerve trunk in vitro.
此外，DS能降低蟾蜍坐骨神经干动作电位的振幅，提示它对钠通道有阻断作用。
Furthermore, ds can obviously inhibit the action potential amplitude of isolated sciatic nerves in toads, indicating that it can block sodium channels.
结果对照组，注射侧坐骨神经干的125碘放射性强度是其它组织的30倍以上。
Results the intensity of radioactivity of 125iodine in the sciatic nerve of the injection side in the control group was 30 times of that in other tissues.
