Abstract:
Repeated injections of recombinant human granulocyte colony-stimulating factor (rhG-CSF) to lethally irradiated mice increased the rate of animal survival. Dose modification factor was 1.20 when 4.5 micrograms/mouse of rhG-CSF was given daily for 14 days after whole body irradiation. Haematological examinations revealed that rhG-CSF increased the number of blood-circulating leukocytes, neutrophils, monocytes and erythrocytes, but not that of lymphocytes and thrombocytes. Spleen weight and number of endogenous spleen colonies were also increased by rhG-CSF treatment compared with the values for mice irradiated only.
