Abstract

Stimulation of the hypogastric nerve to the guinea pig vas deferens in the presence of phenoxybenzamine produced an enhanced release of both dopamine-beta-hydroxylase (EC 1.14.2.1) and norepinephrine. Addition of colchicine, vinblastine, or cytochalasin-B to the incubation medium caused an almost complete inhibition of release of both the amine and the enzyme. Colchicine and cytochalasin-B produced a blocking effect but did not, however, modify the ratio of dopamine-beta-hydroxylase to norepinephrine recovered in the bath fluid. The findings indicate that norepinephrine and dopamine-beta-hydroxylase are released from sympathetic nerve terminals by exocytosis and that this process is dependent upon the integrity of both microtubules and microfilaments.

摘要

在苯氧苄胺存在的情况下,刺激豚鼠输精管的腹下神经会导致多巴胺-β-羟化酶(EC 1.14.2.1)和去甲肾上腺素的释放增加。向孵育培养基中添加秋水仙碱、长春花碱或细胞松弛素B几乎完全抑制了胺和酶的释放。秋水仙碱和细胞松弛素B产生了阻断作用,但并未改变浴液中回收的多巴胺-β-羟化酶与去甲肾上腺素的比例。这些发现表明,去甲肾上腺素和多巴胺-β-羟化酶通过胞吐作用从交感神经末梢释放,并且这一过程依赖于微管和微丝的完整性。
