目的 观察加压素 (VP)免疫反应阳性神经元在下丘脑交叉上核中的分布。方法 采用免疫细胞化学方法显示下丘脑交叉上核的VP阳性神经元。结果 在交叉上核的背内侧亚核有大量的VP免疫反应阳性神经元的胞体和纤维。结论 VP阳性神经元在交叉上核中有明显的区域分布
Objective To observe the distribution of vasopressin (VP) immunoreactive neurons in the suprachiasmatic nucleus of the hypothalamus. Methods The VP positive neurons in the suprachiasmatic nucleus of the hypothalamus were demonstrated by immunocytochemistry. RESULTS: The dorsal medial subnucleus of the suprachiasmatic nucleus contained a large number of somatic cells and fibers of VP immunoreactive neurons. Conclusion VP positive neurons have obvious regional distribution in the suprachiasmatic nucleus
