采用未处理与秋水仙素处理的免疫组织化学方法,结合扫描电镜对大鼠第3脑室壁后叶加压素神经元的分布进行了较系统的观察和研究.结果显示:秋水仙素处理后,后叶加压素免疫反应细胞明显增多,可分大中小三类.在脑室各个平面均可见后叶加压素免疫反应细胞,其中以室旁核平面为主,首次发现在交叉后区和正中隆起平面亦有散在的后叶加压素免疫反应细胞.扫描电镜观察第3脑室表面有接触脑脊液神经元. The distribution of vasopressin neurons in the third ventricular wall of rats was systematically observed by scanning electron microscopy and immunohistochemistry with no treatment and colchicine treatment.The results showed that after colchicine treatment , Vasopressin immunoreactive cells increased significantly, can be divided into three categories in all ventricles are visible vasopressin immunoreactive cells in all planes, of which paraventricular nucleus plane mainly for the first time found in the cross after the area and Elevated vasopressin immunoreactive cells were also found in the central uplift plane, and cerebrospinal fluid neurons were exposed on the surface of the third ventricle by scanning electron microscopy.
