[Cytochemical characteristics of hematopoietic elements in laboratory animals]

Distribution of alkaline and acid phosphatases, L-naph-thylacetateesterase, peroxidase, lipids and glycogen was studied in the blood cells and bone marrow of mongrel albino rats and guinea-pigs by means of cytochemical methods. The intensity of reactions was assessed by Karlow's method. Cytoenzymatic characteristics of the hemopoietic elements and the character of changes in their metabolism during cell differentiation and maturation were ascertained. Quantitative species differences in the content of chemical substances in the blood and bone marrow cells of rats and guinea-pigs were revealed.
