Abstract:
The effects of recombinant human granulocyte colony stimulating factor (rhG-CSF) on the survival rate and hemopoiesis after allogeneic bone marrow transplantation (BMT) was examined. Specific pathogen-free (SPF) C3H mice, kept in a flexible isolator for germ-free animals, received 10Gy of total body irradiation (TBI), and an allogeneic BMT 24 hours later. The 14 day survival rate was 33%. When the mice were received rhG-CSF (30 micrograms/kg/day subcutaneously) daily for 2 weeks following BMT, the 14 day survival rate rose to 79%. The effect of rhG-CSF treatment on hemopoiesis in BMT mice resulted in higher neutrophil counts in the peripheral blood by day 14 post-BMT. Administration of rhG-CSF after allogeneic BMT benefited survival rate and neutrophil recovery without any apparent complications.
