Abstract
Proliferation of bone marrow erythroblasts in patients with chronic renal disease was studied by combined application of cytophotometric measurement of the DNA content and3H-TdR labeling in vitro. A striking decrease of3H-TdR labeling was found in most of the cases. The proportion of diploid (G0 + G1) as well as of tetraploid unlabeled cells (G2) was increased. The data suggest a disturbed induction of DNA synthesis of resting cells as well as an arrest of cells in G2 being responsable for ineffective cell production in this disease. Das Proliferationsverhalten der Erythroblasten im Knochenmark von Patienten mit chronischem Nierenversagen wurde mit Hilfe der kombinierten zytophotometrischen DNA-Messung und autoradiographischen in vitro3H-TdR-Markierung untersucht. In den meisten Fällen wurde eine deutliche Verminderung der3H-TdR-Markierung gefunden. Dabei war der Anteil unmarkierter diploider (G0 + G1) und tetraploider Zellen erhöht. Die Ergebnisse lassen sowohl eine gestörte Induktion der DNA-Synthese der Ruhezellen als auch eine Blockierung der Zellen in G2 vermuten, die für die ineffektive Zellproduktion bei dieser Erkrankung ursächlich sind.Keywords
