Abstract
  1. Diphenylhydantoin (DPH) and potassium significantly prevent ouabain intoxication without preventing the inotropic effects of ouabain in the guinea-pig isolated heart.2. The antiarrhythmic effect of DPH and K on ouabain-induced toxicity appears to be related to their ability to reduce ouabain accumulation by the myocardium and thereby prevent the intracellular Na and K changes which lead to the arrhythmic state.
摘要
  1. 苯妥英钠(DPH)和钾可显著预防哇巴因中毒,同时又不会阻止哇巴因对豚鼠离体心脏的变力作用。2. DPH和钾对哇巴因诱导的毒性的抗心律失常作用,似乎与其降低心肌对哇巴因的蓄积能力有关,从而防止导致心律失常状态的细胞内钠和钾的变化。
