We have registered the contractions of the frog's abdominal muscle in Ringer's solution. The contractions were produced either by acetylcholin or by succinyldicholin. The graphics showed that the succinyldicholin contractions were much slower than the acetylcholin ones. The tracings were not equalized by a preliminary addition of eserin. We conclude that acetylcholine excites the fast fibers and that succinyldicholin excites the slow fibers of the muscle.
我们已记录了青蛙腹肌在任氏液中的收缩情况。收缩是由乙酰胆碱或琥珀酰二胆碱引起的。图表显示，琥珀酰二胆碱引起的收缩比乙酰胆碱引起的收缩要慢得多。预先加入毒扁豆碱并不能使描记曲线变得平缓。我们得出结论：乙酰胆碱刺激肌肉的快纤维，而琥珀酰二胆碱刺激肌肉的慢纤维。
