摘　　要：本文应用ABC法观察了36-40周人胎下丘脑内ACTH_(1-39)免疫反应阳性神经元的分布及形态特征。胞体分布在下丘脑漏斗核及视上核内,呈圆形或椭圆形,突起少并呈短的锥体形。ACTH(1-39)免疫反应阳性神经纤维明显稀少,只在室周层、漏斗核、室旁核可以见到。未见有伸入第三脑室内的此类神经纤维。本实验首次在人胎下丘脑视上核内观察到ACTH_(1-39)免疫反应阳性神经元胞体。The distribution and morphological features of ACTH1-39 immunoreactive neurofibers were studied on 6 human fetus (36-40 weeks of fetal life) . ACTH1-39 immunoreactive cell bodies were found in the infundibular nucleus and adjacent lateral regions of the hypothalamus. The cell bodies were elliptic or round,and the processes were short, thick-pyramidal in shape. ACTH1-39 immunoreactive neurons were found in the supraoptic nucleus. The majority of these neurons were located in the dorso-medial part of the dorsolateral division of the nucleus; some neurons were localized in its ventromedial division; and a few of them were scattered in its dorsomedial division. The shape of these ACTH1 -39 immunoreactive neurons were similar to the immunoreactive neurons in the infundibular nucleus.
