MORPHOMETRIC INDICATORS OF AORTA WALL LAYES UNDER RADIATION

Abstract

It is known that structural-geometric changes take place in the vessel wall for a lifetime, as do other organs. The morphometric changes that develop in the aortic wall are caused by environmental and endogenous pathological factors that affect it. In the morphometric variation of aora wall layers, it occurs first in the endothelial layer and intima, then in the elastic fibers and muscle layer, which is little studied in scientific studies (Averkin N.S. et al., 2019; Strajesko I.D. et al., 2012). The studies were conducted mainly in experimental animals, in which morphological and morphometric effects were studied as a result of environmental influences. But there are almost no scientific studies devoted to the changes that develop in the walls of the aorta and large arteries under the influence of radiation. Therefore, in this research study, our main goal was to analyze the morphometric changes that develop under the influence of radiation in the aortic wall layers of experimental animals.
