Abstract
  1. Tetramisole (100 mug/ml) paralysed live Ascaris in 3 min.2. Tetramisole (10 mug/ml) caused a sustained contraction of the isolated somatic muscles of the worm. This contraction was not blocked by curare nor by piperazine.3. Tetramisole reduced the resting potential of Ascaris muscle from 34+/-4 to 10+/-1 mV.4. Tetramisole caused contraction of Ascaris muscle previously depolarized with high K(+) solutions. This observation suggests that tetramisole can induce a contracture that is independent of membrane depolarization.
摘要
  1. 四咪唑(100微克/毫升)在3分钟内使活蛔虫麻痹。

  2. 四咪唑(10微克/毫升)引起蛔虫离体体壁肌肉的持续收缩。这种收缩不受箭毒或哌嗪的阻断。

  3. 四咪唑使蛔虫肌肉的静息电位从34±4毫伏降至10±1毫伏。

  4. 四咪唑使先前用高钾溶液去极化的蛔虫肌肉发生收缩。这一观察结果表明,四咪唑可诱导一种与膜去极化无关的挛缩。
