Neutrophil kinetics in man studies using autotransfusion of3H-DFP labeled blood cells and autoradiography

SummaryNeutrophil kinetic studies were performed by autotransfusion of3H-DFP labeled blood cells and subsequent autoradiographic analysis of the circulating neutrophils. This method allowed neutrophil specific data to be determined under normal as well severe neutropenic and neutrophilic conditions. This was demonstrated by examination of hematologically normal subjects, patients with neutropenia, infection or polycythemia vera whose blood neutrophil counts ranged between 50 and 21,500 per μl. Moreover studies at different stages of chronic myelocytic leukemia were performed.ZusammenfassungNeutrophilen-kinetische Studien wurden mit Hilfe der Autotransfusion von3H-DFP-markierten Blutzellen und anschließender autoradiographischer Analyse der zirkulierenden Neutrophilen durchgeführt. Diese Methode ermöglichte die Bestimmung Neutrophilen-spezifischer Daten sowohl bei normaler als auch bei erhöhter Blutneutrophilenzahl und bei Neutropenie. Untersucht wurden hämatologisch gesunde Probanden, Patienten mit Neutropenie und Polycythaemia vera, deren Neutrophilenzahl in einem Bereich zwischen 50 und 21500 pro μl lagen. Außerdem wurden Patienten mit chronisch myeloischen Leukämien untersucht.
