用免疫组织化学ＰＡＰ法对加压素样神经元在树丘脑室旁核中的分布进行了观察，并同时对比了加压素样神经元在大鼠和豚鼠室旁核中的分布情况，结果发现：加压素样神经元在室旁核中的分布有较大的种属差异性．差异主要表现在室旁核内侧区的位置，内外区和后区加压素样神经元的密度，距离第三脑室的距离等方面．此外，３种动物室旁核所含大、中、小加压素样神经元的比例亦有种属差异性．

The distribution of vasopressin-like neurons in the paraventricular hypothalamic nucleus was observed by immunohistochemical PAP method. Meanwhile, the distribution of vasopressin-like neurons in paraventricular nucleus of rats and guinea pigs was also compared. Results It was found that the distribution of vasopressin-like neurons in the paraventricular nucleus had greater genus differences. Differences mainly in the medial paraventricular nucleus location, inner and outer areas and posterior vasopressin-like neurons density, the distance from the third ventricle and so on. In addition, the proportion of large, medium and small vasopressin-like neurons contained in the paraventricular nucleus of the three animal species also varies from species to species.
