[Impulse-cytophotometric determination of DNA content in blood cells in patients with leukemia]

The method of impulse cytophotometry was applied for determination of DNA content of blood cells in patients with various types of leukaemia. It was found that at the time of improvement in acute leukaemia the proportion of cells in the non-proliferative stage increases. In chronic leukaemias the improvement was associated with shifts in reverse direction.
