Abstract
  1. Canine Purkinje fibres were superfused in vitro and the electrical and mechanical effects of the local anaesthetics benzocaine and procaine were studied in the absence and in the presence of other agents.2. Both benzocaine (1 x 10(-4)-5 x 10(-4)m) and procaine (6 x 10(-5)-2.5 x 10(-4)m) decreased slightly the amplitude of the upstroke and markedly the duration of the action potential. The plateau was shifted to more negative values and the force of contraction was decreased. These effects were dose-dependent.3. The local anaesthetics abolished the spontaneous activity induced by strophanthidin (5 x 10(-7)m) by flattening the oscillatory potential in diastole and increased the force of contraction under these circumstances.4. The local anaesthetics significantly delayed the time of the onset of the spontaneous activity induced by strophanthidin (10(-6)m). Also, the intensity of the stimuli had to be increased and the rate of discharge of intoxicated fibres was slower in the presence of local anaesthetics. In contrast, the positive inotropic effect was little affected.5. The local anaesthetics reduced but did not block the inotropic action of norepinephrine and high Ca; and did not abolish (while Mn did) small action potential in 27 mm-K-depolarized fibres.6. In fibres treated with local anaesthetics, lowering Ca did not result in a force rebound and administration of caffeine or exposure to low Na resulted in a larger increase in force.7. In fibres loaded with Ca, local anaesthetics caused an increase in force.8. Local anaesthetics decreased the force more when the external Na concentration was lower.9. This work shows that the local anaesthetics alter the mechanical performance of Purkinje fibres and lead to a depression of the strophanthidin induced oscillatory potential. As for the mechanism for these changes, the present experiments support the hypothesis that local anaesthetic agents have an antiarrhythmic action by decreasing intracellular Na and therefore intracellular Ca as suggested by Perry, McKinney & DeWeer (1978) on the basis of experiments on nerve.
摘要
  1. 犬浦肯野纤维在体外进行灌流,研究了局部麻醉药苯佐卡因和普鲁卡因在有无其他药物存在时的电效应和机械效应。

  2. 苯佐卡因(1×10⁻⁴ - 5×10⁻⁴m)和普鲁卡因(6×10⁻⁵ - 2.5×10⁻⁴m)均使动作电位上升支幅度略有降低,动作电位持续时间显著缩短。平台期移向更负的值,收缩力降低。这些效应呈剂量依赖性。

  3. 局部麻醉药通过使舒张期振荡电位变平,消除了毒毛花苷(5×10⁻⁷m)诱导的自发活动,并在这种情况下增加了收缩力。

  4. 局部麻醉药显著延迟了毒毛花苷(10⁻⁶m)诱导的自发活动的起始时间。此外,在局部麻醉药存在的情况下,刺激强度必须增加,中毒纤维的放电频率较慢。相比之下,正性肌力作用受影响较小。

  5. 局部麻醉药减弱但不阻断去甲肾上腺素和高钙的正性肌力作用;并且在27mm - K⁺去极化纤维中不消除(而锰可消除)小的动作电位。

  6. 在局部麻醉药处理的纤维中,降低[Ca]ₒ不会导致力的反弹,给予咖啡因或暴露于低钠会导致力的更大增加。

  7. 在加载钙的纤维中,局部麻醉药导致力增加。

  8. 当外部钠浓度较低时,局部麻醉药使力降低得更多。

  9. 这项工作表明,局部麻醉药改变了浦肯野纤维的机械性能,并导致毒毛花苷诱导的振荡电位降低。至于这些变化的机制,目前的实验支持这样的假设,即局部麻醉药通过降低细胞内钠从而降低细胞内钙而具有抗心律失常作用,正如佩里、麦金尼和德韦尔(1978年)基于对神经的实验所提出的那样。
