[Physiological methods of treatment of patients with polycythemia vera].

Based on an analysis of the data pertaining to changes in the level of erythropoietin, chalones and stress hormones in the blood of patients with polycythemia vera after bloodletings and cytapheresis it is concluded that chalones participate in the development of a remission owing to the inhibition of the clone of mutant cells. The role of stress hormones is reduced to the potentiation of the effect of chalones, that of erythropoietin to the triggering of the proliferation of the cellular clone.
