Abstract

The uptake of dehydroemetine by adrenergic neurones was studied indirectly by testing the ability of various procedures to prevent or reverse adrenergic neurone blockade in the periarterially stimulated rabbit isolated ileum. Adrenergic neurone blockade was prevented but not reversed by equilibration with dehydroemetine at low temperature (0 degrees C), in the absence of sodium or in the presence of tetrodotoxin. Noradrenaline, cocaine, potassium deprivation and potassium excess did not modify the adrenergic neurone blocking action of dehydroemetine.

摘要

通过测试各种方法预防或逆转兔离体回肠动脉周围刺激引起的肾上腺素能神经元阻滞的能力,间接研究了脱氢吐根碱被肾上腺素能神经元的摄取情况。在低温(0℃)、无钠或有河豚毒素存在的情况下,用脱氢吐根碱平衡可预防但不能逆转肾上腺素能神经元阻滞。去甲肾上腺素、可卡因、钾缺乏和钾过量均未改变脱氢吐根碱的肾上腺素能神经元阻滞作用。
