The distribution of angiotensin II cell bodies in the thalamus of the rat was studied by means of intratissue injections of colchicine and using an indirect immunoperoxidase technique. The densest clusters of immunoreactive perikarya were observed in the nuclei geniculatum laterale, medialis dorsalis, ventralis posterior, centralis lateralis, centralis medialis and anterior dorsalis, whereas the nuclei lateralis posterior, lateralis and geniculatum laterale dorsalis had the lowest density. In other thalamic nuclei, geniculatum mediale, lateralis anterior, paraventricularis and ventralis medialis, the density of angiotensin II cell bodies was intermediate. In all these thalamic nuclei, small, round immunoreactive cells with short processes were observed.
采用秋水仙碱组织内注射法并运用间接免疫过氧化物酶技术，研究了大鼠丘脑内血管紧张素II细胞体的分布情况。在外侧膝状体核、背内侧核、腹后核、外侧中央核、内侧中央核和背前核中观察到免疫反应性核周体最密集的簇，而后外侧核、外侧核和背外侧膝状体核的密度最低。在其他丘脑核团，即内侧膝状体核、前外侧核、室旁核和内侧腹核中，血管紧张素II细胞体的密度处于中等水平。在所有这些丘脑核团中，均观察到具有短突起的小圆形免疫反应性细胞。
