Abstract
  1. The influence of barbiturates on neuromuscular transmission at end-plates of frog sartorius muscles was investigated electrophysiologically on preparations bathed in Ringer solution containing a low concentration of calcium and a high concentration of magnesium.2. Effects of a convulsant barbiturate, 5-(2-cyclohexylideneëthyl)-5-ethyl barbituric acid (CHEB), were compared with those of phenobarbitone.3. CHEB and phenobarbitone increased the mean quantum content of the end-plate potentials and decreased the mean amplitude of the miniature end-plate potentials.4. Both barbiturates enhanced the duration of the nerve-terminal action potential and had little or no effect on the effective resistance of the skeletal muscle membrane.
摘要
  1. 在含有低浓度钙和高浓度镁的林格氏液中浸泡的青蛙缝匠肌终板上,用电生理学方法研究了巴比妥类药物对神经肌肉传递的影响。

  2. 将惊厥性巴比妥类药物5-(2-环己叉乙基)-5-乙基巴比妥酸(CHEB)的作用与苯巴比妥的作用进行了比较。

  3. CHEB和苯巴比妥增加了终板电位的平均量子含量,降低了微小终板电位的平均幅度。

  4. 两种巴比妥类药物均延长了神经末梢动作电位的持续时间,对骨骼肌膜的有效电阻几乎没有影响或没有影响。
