Morphometric Indicators of Morphological Structures of the White Rats Spleen in Postnatal Ontogenesis

Abstract

This article is devoted to the actual problem-the development of the spleen as an organ of the immune system at the stages of postnatal ontogenesis. The immunocompetent compartment of the spleen parenchyma is represented by its white pulp (BP), where two main B- and T-dependent zones are formed, that is, areas of localization of mainly B- and T-lymphocytes. These are, respectively, lymphoid follicles (LF) and periarterial lymphoid couplings (PALM)  In an experiment on 40 white outbred male rats of 5 age groups using histological and morphometric methods followed by statistical analysis, data on the morphometric parameters of the spleen of white rats in postnatal ontogenesis are presented. It was established that the studied quantitative parameters of the white remote control of white rats undergo significant postnatal changes, expressed in different age aspects.  morphometric development
