儿茶酚胺、神经肽、类固醇和环境变化的相互作用会影响催乳素的分泌。近十年来,有大量文献集中论述了鸦片肽、儿茶酚胺和类固醇激素对催乳素和促性腺激素调节的相互作用。本文将对这一问题进行重点复习。一、多巴胺的催乳素抑制因子作用下丘脑产生的多巴胺,经正中隆起和下丘脑-垂体-门腺系统到达垂体,对垂体的催乳素细胞起有持续抑制作用。多巴胺在神经元轴突末梢合成,神经元细胞体位于下丘脑弓状核。多巴胺经神经分泌到门腺系统,并经门腺系统血流到垂体前叶,此即为结节漏斗部多巴胺系统。恒河猴垂体茎内的多巴胺浓度较周围组织浓度约高八倍。经生物化学
The interaction of catecholamines, neuropeptides, steroids and environmental changes affects prolactin secretion. In the last decade, a large number of papers have focused on the interaction of opiate peptides, catecholamines and steroid hormones with prolactin and gonadotropin regulation. This article will focus on this issue review. First, dopamine prolactin inhibitory factor hypothalamic dopamine produced by the median uplift and the hypothalamus - pituitary - gland system to reach the pituitary, the pituitary prolactin cells have a continuous inhibitory effect. Dopamine is synthesized at the axon terminals of neurons, which are located in the hypothalamic arcuate nucleus. Dopamine is secreted by the nervous system to the glandular system, and the blood flow to the anterior pituitary via the glandular system, which is the nodular funnel Department of dopamine system. Doping concentrations of dopamine in the pituitary stems of rhesus monkeys are about eight times higher than those in the surrounding tissues. Biochemistry
