Bone marrow hemopoiesis at emotional stress reactions of various intensity upon a background of exposure to low dose ionizing radiation

Rats preliminary exposed to 0.9 Gy of ionizing radiation showed disturbances in the development of adaptive reactions of blood system to emotional stress, compensatory capacity of the blood system being decreased. A degree of the disturbances directly depended on the duration and intensity of the emotional stress: at the prolonged intensive emotional stress a sharp decrease in the adaptive and compensatory capacity of blood system was found; at short intensive or moderate stress the changes in the adaptive and compensatory capacity of hemopoiesis were less pronounced. A combined action of low-dose ionizing radiation and short weak emotional stress did non affect the adaptive and compensatory capacity of hemopoietic system.
