The effects of single-dose total-body X irradiation (TBI) on the granulocyte/macrophage progenitor cell (GM-CFC) population in bone marrow and blood of dogs were studied for dose levels of 0.78 and 1.57 Gy up to 164 days after irradiation. The blood GM-CFC concentration per milliliter was depressed in the first 7 days in a dose-dependent fashion to 5-16% of normal after 0.78 Gy and to between 0.7 and 5% after 1.57 Gy. The bone marrow GM-CFC concentration per 10/sub 5/ mononuclear cells, on the other hand, was initially reduced to about 45% of the average pre-irradiation value after 0.78 Gy and to 23% after 1.57 Gy. The regeneration within the first 30 to 40 days after TBI of the blood granulocyte values and the repopulation of the bone marrow GM-CFC compartment was associated with both a dose-dependent increase in the S-phase fraction of the bone marrow GM-CFC and a dose-dependent increase in colony-stimulating activity (CSA) in the serum.
