In 2 weeks after the clinical recovery of rats from radiation sickness (appearing as a result of irradiation by the dose of 150 r) there was an increase of resistance of the animals to repeated x-ray irradiation by the same dose, to the absolutely lethal dose (650 r), as well as to the effect of the absolutely lethal dose of diphtheritic toxin and morphine. However, contrary changes were revealed in repeated x-ray irradiation of the majority of rats 2 weeks after their recovery from the radiation sickness induced by the primary dose of 450 r. Only in a few cases the resistance of rats to repented irradiation with the same dose was increased after the first irradiation with the dose of 450 r. The second irradiation (150 r and 450 r) decreased the resistance of the animals to the third irradiation by the same dose. This work demonstrated that the differences in the reactivity of the animals at the moment of repeated irradiation may be connected with the changed activity of the hypophyseal-adrenal system.
