[Lymphoid formations of the spleen in persons of different ages]

Histological preparations of the spleen obtained from 64 corpses of persons of both sex and various age died from traumas, asphyxia, acute cardiac ischemia have been investigated. Microscopical anatomy of the spleen lymphoid formations has been described at various age periods, as well as structural interrelations of periarterial lymphoid muffs and lymphoid nodules with each other, with arteries and trabeculae. The periarterial lymphoid muffs embrace the splenic arteries immediately as they leave the trabeculae and get into the periarterial zones of the lymphoid nodules. The data have been obtained on relative contents of the main splenic structural components and on size of the lymphoid nodules and their germinative centers at various age in accordance with the modern age periodization, intensity of the age factor influence on these parameters is demonstrated. Problems of morphofunctional interrelations of certain splenic structures are discussed.
