The effect of bretylium and guanethidine has been studied on the uptake and the spontaneous and reserpine-induced release of [(3)H]-noradrenaline in the rat heart and in the splenic nerve endings of the cat. Bretylium and guanethidine inhibited the uptake by the heart of circulating [(3)H]-noradrenaline. Bretylium blocked spontaneous and reserpine-induced release of [(3)H]-noradrenaline, while guanethidine caused release and partially antagonized the reserpine-induced release. Both compounds produced a transient liberation of [(3)H]-noradrenaline from splenic nerves, but blocked the release of the [(3)H]-catechol amine following stimulation of the splenic nerve.
已研究了溴苄铵和胍乙啶对大鼠心脏及猫脾神经末梢摄取、自发释放和利血平诱导释放[(3)H]-去甲肾上腺素的影响。溴苄铵和胍乙啶抑制心脏对循环中[(3)H]-去甲肾上腺素的摄取。溴苄铵阻断[(3)H]-去甲肾上腺素的自发释放和利血平诱导的释放,而胍乙啶则引起释放并部分拮抗利血平诱导的释放。两种化合物均使脾神经中的[(3)H]-去甲肾上腺素短暂释放,但阻断了刺激脾神经后[(3)H]-儿茶酚胺的释放。
