[Regularities of differentiation of lymphoid structures in the walls of hollow internal organs of man].
The regularities of the structure of lymphoid tissue in the hollow visceral walls were found while analyzing the results of studies conducted in the author's laboratory by examining a lot of materials--corpses of the individuals who had at their death had no inflammatory or other diseases which could greatly affect the structure of immune organs. In the walls of digestive, respiratory, and urinary organs, the author followed up the development of lymphoid structures from the lymphoid cells diffusely scattered in the mucosa to the accumulation of these cells and formation of lymphoid nodules with and without reproduction centers. He also analyzed the causes promoting the concentration of lymphoid cells as aggregates, the formation of lymphoid nodules in the viscera having their different structure and uses.
