[Functional activity of the splenic cells in the late periods after the administration of antitumor preparations with various mechanisms of action].

In experiments on CBA/Lac J mice it was found that the course administration of adriamycin (0.95 mg/kg), vinblastine (0.24 mg/kg) and cyclophosphan (27 mg/kg) in 1/10 LD50.10 causes persistent disturbances of the functional activity of the lymphoid tissue manifesting by inhibition of the proliferative response of the spleen lymphocytes to T- and B-cell mitogens one month and to a lesser extent three months after cytostatic action. The lymphotropic effect of adriamycin is due to the predominant damage of the functional activity of T-lymphocytes. Vinblastin suppresses T- and B-cell link of the immunity system and the inhibitory effect of cyclophosphan is directed mainly to B-cell population.
