为了证实中国树鼩下丘脑视上核和室旁核内催产素（ｏｘｙｔｏｃｉｎ， ＯＴ）能神经元的形态和神经维在神经垂体内的分布，采用ＡＢＣ免疫组织化学技术进行了观察。结果发现，在各核团内，ＯＴ能胞体均散在分布，大多呈圆形或卵圆形，少数呈梭形或星形。核圆形，大多偏心位。免疫反应产物弥散分布于胞浆内。分布在正中隆起（ＭＥ）和垂体神经部内的ＯＴ能神经纤维直径微细，数目少，免疫反应性弱，但有数目较多，体积较大且大小不等的ＯＴ免疫反应凝聚体和赫令体。提示中国树鼩ＯＴ能的与加压素（ＶＰ）能的胞体及神经纤维免疫反应性存在差异。
In order to confirm the morphological and neurovascular distribution of neurotrophic neurons in the supraoptic nucleus and paraventricular nucleus of the Chinese tree shrews in the neurohypophysis, ABC immunohistochemistry was used to observe the distribution of neurotrophic neurons in the supraoptic nucleus and paraventricular nucleus. The results showed that, in each nucleus, OT cells are scattered throughout the body, mostly round or oval, a few were spindle or star. Nuclear round, most eccentric position. Immune reaction products dispersed in the cytoplasm. OT nerve fibers distributed in the middle meridian (ME) and the pituitary nerve are small in diameter, few in number and weakly immunoreactive, but there are a large number of OT immuno-cohesive aggregates with large size and size, . Suggesting that there is a difference in the immunoreactivity between Chinese tree 鼩 OT and vasopressin (VP) -based somatic cells and nerve fibers.
