[Morphology of the palatine tonsil lymphocytes in chronic tonsillitis using data of electron microscopic...

Electron-microscopic and electron-radioautographic examinations of the palatine tonsil lymphocytes in 20 patients with chronic decompensated tonsillitis, aged 21-50, have revealed the proliferation of poorly differentiated T- and B-lymphocyte pools in the lymphoid tissue of the tonsils; these processes manifest by an intensive 3H-thymidine incorporation into the minor lymphocytes of different types. A high level of the RNA radioactive precursor incorporation in B-lymphocytes indicates a constant differentiation of this lymphocyte population. The biological essence of intensive incorporation of protein radioactive precursors in B-lymphocytes appears to consist in the maximal production of active protein substrates mediating the humoral immunity in chronic tonsillitis.
