[Morphological and histoenzymatic characteristics of the bone marrow in the blastic crisis of chronic myeloleukosis].

Morphological and histoenzymatic characteristics of bone marrow in blastic crisis of chronic myeloleukemia are presented. Its involvement is proved to be irregular even within the limits of small topographic zones. The later is of importance in establishing the diagnosis of the disease by trepine biopsies in hematological practice. The histoenzymatic analysis of the cells in blastic crisis, indicates low degree of their differentiation reaching presumably the level of committed elements of hemopoiesis.
