[Cytoarchitectonics of lymph node parenchyma during exposure to increased pressure].

Quantitative relations between the lymphoid tissue cells in various zones of the popliteal lymph node were stated in mice kept in the barochamber under pressure of 3 atm for 0.5, 1, 2, 4 and 6 days. Decreasing number of small lymphocytes and reticular cells was observed. The number of middle lymphocytes increased at the beginning, and the large ones--after the first day of the experiment. Fluctuations in the number of plasmic cells demonstrate their sensibility to an increased pressure.
