[Significance of quantitative enzyme-cytochemical studies for hematologic cytology]

Enzyme-cytophotometrical investigations allow evaluation of enzyme activity within single, morphologically classified cells. Special problems like development of blood cells, bone marrow cells or of macrophages may thus be studied. Knowledge about the kinetics of granulopoiesis allows a better understanding of altered functional characteristics of abnormally developed blood cells. Enzyme cytochemical microdensitometry promises to be a useful tool in haematological cytology.
