The damaging effect of hypokinesia on the functional state of lymphoid tissue in the wall of the duodenum and on the lymphoid plaque was established. It was found that the processes of cell destruction, suppression of the plasma reaction and blast transformation of cells are most pronounced in the wall of the duodenum. In the lymphoid plaque, along with a high level of destructive processes in lymphoid cells, lymphocytopoiesis is preserved in the centers of proliferation of lymphoid nodules and the proportion of plasma cells increases in the internodal zone, which indicates the development of compensatory processes under the long-term influence of hypokinesia.
