摘要
本实验将胎龄为１５ｄ胎鼠的下丘脑组织植入到成年Ｔｈｙ－１小鼠大脑皮质３，１，２区、侧脑室和丘脑内，移植３０ｄ后，取材，常规制备，光镜观察，结果为：在不同区域的下丘脑移植物中可见大、中、小３类神经元。大型神经元的尼氏体聚集在细胞边缘，胞浆中有未被染色的空白区。中型细胞内尼氏体含量多，核浆比小。小型细胞体积小，形状类似中型细胞。各种细胞突起明显可见。脑室内移植物发育最好，皮质内移植物发育最差。本文并对上述现象出现的原因进行了探讨。
5d fetal hypothalamus tissue was transplanted into the areas 3,
1,2 of carebral codex,latoral ventricle and thalamus of adult Thy-1mouse in our experiment;We
made our preparations by 30dafter transplantation.There are large,middle and small neurons in
the hypothalamus grafts of differ-ent peitions.The Nissl subetances in large cells were
distributed peripheral and eytoplasmic colloidalinclusions are regarded as the neurosecretory
product of these cells.The middle cells included a lot ofNissl substances and its nuclear-plasm
ratio is small.Small cell is like the shape of middle one.Devel-opment of the cells in the grafts
transplanted in lateral ventricle is very well,but in cerebral cortexlower.We discussed the
principle of the phenomena in our results.
