Abstract:
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.
