[G-CSF and G-CSF receptor]

Relationship between leucocytosis and G-CSF blood concentration were examined. Increase in blood concentration of G-CSF of surgical patient and dialysis patient with leucocytosis were noticed. Determination of G-CSF receptor on leucocyte was performed by the flow cytometry using biotinylated G-CSF. Modulation of G-CSF receptor on leucocyte at surgery and dialysis was identified in vivo. Studies of G-CSF blood concentration and modulation of G-CSF receptor are useful in analysis of dynamics of leucocyte and analysis of infectious disease.
