野木瓜注射液对牛蛙坐骨神经传导的影响

10％野木瓜注射液（InjectionStauntoniae，IS）涂布于离体牛蛙坐骨神经8min后，神经干复合动作电位诸成分的潜伏期都发生了显著性的延长，但只对C2成分的幅度有显著性影响；而50％IS不仅使复合动作电位各类成分的潜伏期都发生了显著性延长，而且使除Aαβ和C1以外的各类成分的幅度有显著性的减小．上述IS的影响具有明显的量效关系．这种阻滞作用是可逆的．

The Effects of Injection Stauntoniae on the Conduction of the Sciatic Nerve in Bullfrog

Injection Stauntoniae (IS) was locally applied on a part of the Sciatic Nerve of Bullfrog. 8 min after administration with 10% IS, the latencies of all components of the copound action potential (cAP) were delayed, but only was the amplitude of cAP of C2 fiber reduced significantly. With 50% IS, the amplitudes of cAP of all fibers except Aab and C1 were reduced significantly. There was dose--dependency between concentration of IS and its effect on nerve conduction. Effects above were reversible.
