We studied the effects of intraperitoneal injections of recombinant human granulocyte colony-stimulating factor (rhG-CSF) according to various administration schedules on the recovery of spleen colony-forming units (CFU-S) and peripheral blood counts, and on the survival of irradiated mice. The sooner and more frequently the mice were injected with rhG-CSF after irradiation, the more enhanced the recovery of CFU-S in bone marrow was obtained on day 7. Twice-daily injections of rhG-CSF from day 0 to day 2 significantly enhanced the recovery of platelets and hematocrit, but two injections of rhG-CSF on only day 0 did not. Twice-daily injections of rhG-CSF from day 0 to day 6 enhanced the recovery of platelets more effectively than twice-daily injections of rhG-CSF from day 1 to day 7, and increased the survival of irradiated mice more effectively than any other examined administration schedules. Twice-daily injections of rhG-CSF from day 0 to day 6 were significantly effective in enhancing the survival of mice irradiated with 8.5-, 9.0-, and 9.5-Gy x-rays, although not effective after irradiation of 10.5-Gy x-rays.
