Isolated preparations of the rabbit vas deferens were incubated with (--)-(3)H-nor- adrenaline. A preferential release of (3)H-noradrenaline was demonstrated after electrical stimulation of the intramural nerves in those tissues labelled with 10 ng/ml (3)H-noradrenaline. There was no preferential release of (3)H-noradrenaline when the vasa were initially labelled with 100 ng/ml (3)H-noradrenaline. It is concluded that low concentrations of (3)H-noradrenaline do not mix homogeneously with the total tissue store but enter a small easily releasable store.
将兔输精管的离体标本与（--）-（3）H-去甲肾上腺素一起孵育。在用10 ng/ml（3）H-去甲肾上腺素标记的那些组织中，电刺激壁内神经后，显示出（3）H-去甲肾上腺素的优先释放。当输精管最初用100 ng/ml（3）H-去甲肾上腺素标记时，没有（3）H-去甲肾上腺素的优先释放。得出的结论是，低浓度的（3）H-去甲肾上腺素不会与整个组织储存均匀混合，而是进入一个小的易于释放的储存库。
