用抗加压素（VP）血清和免疫组化技术，观察了中国树下丘脑视上核（SON）和室旁核（PVN）内VP能种经元的形态和神经纤维的分布。VP能胞体的形态，在SON主部多呈梭形，少数呈多角形；在SON交叉后部，多是多角形，少数是梭形；在PVN，以多角形为主，少数为梭形．VP能纤维的分布：在PVN与SON生部之间，特别是与视交叉上区和现柬背内侧区之间，纤维细而直，多平行分布．在PVN后半外侧，可见部分纤维呈内侧-背外侧向分布；在SON交叉后部的背外侧，纤维是朝向正中隆起处汇集的趋势，其中部分纤维呈串珠状；在正中隆起内带，纤维呈西外侧-内侧向和吻-屠向密集分布，有少数大小不等的免疫反应阳性的聚集体；在正中隆起外带，特别在会体门脉毛细血管排周围，有致密的、成群分布的免疫反应阳性点状结构；在漏斗柄和垂体神经部，可见致密的免疫反应阳性纤维和Herring体，在神经部内的窦状毛细血管周围有致富的、大小不等的免疫反应阳性点状结构．
The VP morphological and nerve fiber distributions in the supraoptic nucleus (SON) and paraventricular nucleus (PVN) of the Chinese tree were observed by anti-vasopressin (VP) serum and immunohistochemistry. The majority of VP cell bodies were fusiform and a few were polygons in the main part of SON. In the rear part of SON crossover, mostly polygons and few were fusiform; in PVN, polygons were the main part, and a few were fusiform. VP can fiber distribution: between the PVN and SON Department of Health, especially with the optic chiasm area and is now Cambodia back medial region between the fiber thin and straight, multi-parallel distribution. In the posterior half of PVN, some of the fibers showed a medial-dorsolateral distribution. At the dorsal lateral to the SON-posterior posterior part, the fibers tended to converge toward the mid-elevation, and some of the fibers were beaded. In the mid- Was western lateral - medial and kiss - Tu dense distribution, there are a small number of immune reaction-positive aggregates of varying sizes; in the middle of the bulge out, especially in the body capillaries around the row of capillaries, dense, clustered Distributed immunoreactive positive dot-like structure; in the funnel handle and pituitary nerve, visible dense immunoreactive fibers and Herring body, within the sinusoid sinusoid in the Ministry of the richer, the size of the immune reaction-positive spots structure.
