AGE-RELATED DYNAMICS OF MORPHOFUNCTIONAL STATE OF THE LYMPHOID TISSUE IN THE WALL OF HUMAN URETER
Cellular composition of the lymphoid tissue in the ureteral epithelium and lamina propria was studied morphometrically in human postnatal ontogenesis using autopsy material obtained from 32 males of different age (from the neonatal period to the II period of mature age). Lymphoid tissue was found to be weakly developed in the ureteral wall during the studied period of human life. Processes of lymphocytopoiesis were not expressed, while there was high activity of cellular destruction. The reduction of the plasma cell numbers by the II period of mature age is a manifestation of a general decrease of functional activity of the lymphoid tissue in the wall of the ureter.
