[Effects of previous small-dose irradiation on blood reaction and survival of mice after subsequent radiation and combined radiation-thermal injuries]. 
CBA x C57BL6 mice pre-exposed to 5 cGy gamma-irradiation then inflicted to LD70/30 acute radiation or combined injuries (radiation + thermal burn).  In such protocol of the experiments preliminary "adaptive" dose radiation did not modify low 30-day survival rate and did not render an influence to the mean survival time.  Leucopenia level and bone marrow devastation in 3 days after sublethal irradiation (4 Gy) or combined injury was similar in mice pre-exposed to low dose radiation (5 cGy) and in their unexposed controls. " Adaptive" dose radiation decreased leukocytes' number within the phase of hemopoiesis recovery (in 14 day after sublethal irradiation or combined injury).
