Age changes cattle lymph nodes histoarchitectonics in postnatal ontogenesis
Journal Title: Біологія тварин - Year 2015, Vol 17, Issue 1
Abstract
Investigated somatic and visceral lymph nodes (LN) 1-, 30-, 120-daily calves and 16-month heifers using complex classical histological techniques. The aim of the study was to determine the characteristics of histoarchitectonics parenchyma of LU different localization, in terms of the concept of its lobuled structure in mammals and patterns of age-related changes lobules lymphoid nodes. Lymphoid lobules in the parenchyma of LN cattle are formed by a set of high-and lowspecialised cell zones, with characteristic for each of them architectonics reticular mesh-work, located in certain pattern relative to each other. All highly specialized zones (deep cortex units, lymph nodules) have a sphere-like shape, and lowspecialized — cylindrical shape (cortical plateau, medulla cords). The basis of lymphoid lobule is a deep cortex units at the poles and the lateral surfaces of which are located all its other components. It was found that the structure and histoarchitectonics lymphoid lobules in the parenchyma of nodes in cattle has some significant differences from similar structures in humans and laboratory animals. Lymphoid lobules parenchyma of LU cattle is characterized by multi-level localization of lymphonodules from cortical lymph nodules plateau to the medulla cords and mosaic location of subunits (parenchyma lobules) between the subcapsular and the portal sinus of lymph nodes. Age conversion of cattle LN parenchyma are conditioned by phased development and spread into the deep lymphoid tissue of two specialized cell zones of lymphoid lobules, to 30 day old — lymph nodules, up to 120 daily — deep cortex units.
