[Effect of contact neutron and gamma therapy on immunity of patients with cancer of the mouth mucosa].

Considerable deviations from the normal indices of T- and B-cell components of the immune system were found in patients with oral mucosa cancer. Some differences in immunity indices after 2 types of contact therapy was established. T-lymphocytes were radiosensitive in contact neutron 252Cf radiation, B-lymphocytes in gamma-beam radiation (60Co). The phagocytic component was characterized by relative radioresistance.
