Ultrastructure of rat cerebral vessels 4 months after gamma irradiation

Abstract

The purpose of this paper was to check the current opinion that one of the late postirradiation changes is early senility (Maxwell, Kruger, 1964). The postirradiation changes of the brain parenchyma are well known from the literature; therefore our investigation is limited to brain capillaries and their closest vicinity. This paper constitutes a fragment of a larger work on the role of connective tissue in the aging brain. Six Wistar male rats of the same brood, about 3 months old, were irradiated over the whole body with gamma rays. Three rats were exposed to a dose of 400 R and three to 800 R. The chosen doses were the lowest and the highest, provoking brain edema but still not lethal. Four months after the exposure the rats were perfused with 4% glutaraldehyde intracardiacly and decapitated. Brain specimens were taken from frontoparietal cortex, lateral ventricle wall, from corpus callosum and griseum pontis. The samples were routinely handled for ultrastructural studies. Observations were performed under electron microscopes showed that the cerebral vessels of both groups of animals were similar.
