title: Leukocyte alkaline phosphatase activity and peripheral changes of granulocyte following administration of granulocyte colony-stimulating factor.
abstract: The rhG-CSF had specificity of stimulation proliferation and differentiation of the neutrophil lineage in which there was an increase of younger stages, the earliest was myelocyte, of granulocyte in circulation. The effect of it was demonstrated within 24 hours of administration and reduced immediately after withdrawal. LAP activity in this condition was normal. The pattern of hematologic change in this condition may mimic CML and leukemoid reaction. It differed clearly from CML, since LAP activity in CML was lower than normal, but LAP activity could not define it from leukemoid reaction. The detection of young cells in peripheral blood through automated measurement of nuclear density by TechniconH*1 was observed for the high sensitivity (100%) and low specificity (54.8%). Furthermore, the study of cell kinetic in bone marrow should be evaluated to complete the cell kinetic effect of rhG-CSF and give a better evaluation for the H*1 blast flag.
