Abstract: | Effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on the number and blastogenesis of lymphocytes were evaluated in clinically healthy dogs treated subcutaneously with rhG-CSF at a dose of 2.5 microg/kg for 3 days. Significant increases in the number of leukocytes and segmented neutrophils were observed after the administration of rhG-CSF. The number of lymphocytes also increased on days 1 and 2 after the treatment. Activities of phytohemagglutinin, concanavalin A, and pokeweed mitogen-induced lymphocyte blastogenesis (LB) were augmented to twice the pretreatment levels by the administration of rhG-CSF. These results suggested that administration of rhG-CSF activated lymphocyte functions such as LB in healthy dogs. |
