[Granulocyte kinetics with radioactive diisopropylfluorophosphate (DF32P) and radiochrome (51Cr)].
Determining granulocyte kinetics with DF32P allows various parameters to be gained during the in-vitro marking, such as the total blood granulocyte pool, circulating granulocyte pool, marginal granulocyte pool, daily granulocyte exchange rate and half decay period of granulocytes. The half decay period of granulocytes, bone-marrow reserve in myelocytes, metamyelocytes and band cells as well as polymorphonuclear neutrophils can be determined by in-vitro marking, with DF32P being intravenously injected. The combination of both procedures with DF32P will reveal the half decay period, pool sizes and exchange rates of the proliferating myelocyte compartiment in bone-marrow and mature blood granulocytes. If 51Cr is used for determining granulocyte kinetics the surface activities of various organs, such as heart, liver, spleen, and lungs, can mainly be determined in addition to the half-life of leucocytes, indicating the degradation or storage of cells in certain areas of the body. In addition to normal values those findings are principally presented which were obtained with in-vitro marking by DF32P and 51Cr in chronic myeloid leukaemia, osteomyelofibrosis or osteomyelosclerosis respectively and in hypersplenism.
