The differentiation of myeloblastic cells presents a problem in cases with a negative peroxidase reaction. The rate of positive reaction varies according to the method of peroxidase reaction. In view of the dissociation between electronmicroscopic findings and the biochemical peroxidase reaction on one hand and the rate of positive peroxidase reaction on the other, the possibility of elevating the rate of positive peroxidase reaction through an improvement of the method has been suggested. Expeiments were therefore carried out by adding 0.1% KCl and 0.01% Glucose in the Sato-Sekiya method to determine the elevationtn of the rate of positive reaction.
