The extraneuronal spontaneous efflux of (3)H-dopamine synthesized endogenously in dopamine terminals has been demonstrated in vitro, by collecting the (3)H amine in superfusates of isolated striatum of the rat previously incubated with (3)H-tyrosine. The (3)H-dopamine newly synthesized appears to be preferentially released. Furthermore, amphetamine and a monoamine oxidase inhibitor (Carton) markedly increased the release of (3)H-dopamine. This effect was also observed with substances normally contained in some striatal neurons: acetylcholine and 5-hydroxytryptamine.
通过收集预先用³H - 酪氨酸孵育的大鼠离体纹状体灌流液中的³H胺,已在体外证明了多巴胺终末内源性合成的³H - 多巴胺的非神经元自发外流。新合成的³H - 多巴胺似乎优先被释放。此外,苯丙胺和一种单胺氧化酶抑制剂(卡托)显著增加了³H - 多巴胺的释放。在一些纹状体神经元中正常含有的物质(乙酰胆碱和5 - 羟色胺)也观察到了这种效应。
