最近从人类胰腺肿瘤中分离出一种释放生长激素(GH)的因子(Guillemin et al. 1982; Rivier et al.)。我982)。使用抗血清对这种生长激素释放因子(GRF)进行免疫组织化学研究,发现下丘脑中存在GRF阳性细胞体,主要是弓形核,在中央凸起处有特别密集的纤维网络(Bloch等人1983年,Bugnon等人1983年,Jacobowitz等人1983年,Merchenthaler等人1984年,Sawchenko等人1985年)。在本研究中,grf免疫反应神经元在弓形核中的分布与酪氨酸羟化酶(TH)的定位进行了比较,酪氨酸羟化酶是将酪氨酸转化为l -二羟基苯丙氨酸(L-DOPA)的酶,在该区域被认为是多巴胺神经元的标志(见Hokfelt et al. 1984b)。
A factor which releases growth hormone (GH) has recently been isolated from a human pancreatic tumour (Guillemin et al. 1982, Rivier et al. I 982). Immunohistochemical studies using antiserum to this GH releasing factor (GRF) have revealed the presence of GRF-positive cell bodies in the hypothalamus, mainly the arcuate nucleus, with particularly dense networks of fibres in the median eminence (Bloch et al. 1983, Bugnon et al. 1983, Jacobowitz et al. 1983, Merchenthaler et al. 1984, Sawchenko et al. 1985). In the present study, the distribution of GRF-immunoreactive neurons in the arcuate nucleus has been compared with the localization of tyrosine hydroxylase (TH), the enzyme converting tyrosine to L-dihydroxyphenylalanine (L-DOPA), which in this area is assumed to represent a marker for dopamine neurons (see Hokfelt et al. 1984b).
