title: [Effect of low doses of ionizing radiation on thymus-dependent humoral immune response and the polyclonal activation of B lymphocytes].
abstract: The exposure of mice to low dose of gamma-rays (10 cGy, 1 cGy/min) increased thymus-dependent humoral immune response and polyclonal activation of B-cells. Injection of hydroquinone eliminated radiation-induced augmentation of polyclonal response of B-lymphocyte. Thymogen decreased significantly the radiation-induced immunostimulation. The study of the dynamics of primary immune response showed that the period of radiation-induced elevation was followed by the phase of profound reduction of antibody formation. Possible negative consequences of action of low doses of ionizing radiation on immune system is discussed.
