RESUMO
Cytogenetic and mitotic disorders were studied in 151 patients with acute non-lymphoblastic leukemia. A significant rise in the incidence of clonal disorders with predominant affection of chromosomes 5 and 7, and an increase in the percentage of cases with the presence of pathologic mitoses in hemopoietic cells have been recorded in patients who, due to their occupation, have been exposed to potentially mutagenic chemical substances.

The analysis of the epidemiological data has evidenced that there exist common factors of the development of varying types of depressions and dysplasias of hemopoiesis and acute non-lymphoblastic leukemias, and has shown the possibility of distinguishing common risk groups in respect to these diseases.

Electron-microscopic studies of the lymphatic nodes in lympho- and reticulosarcomas of man showed that tumoral cells retained the ultrastructural signs of initial normal cells (lymphoid or reticular) in the degree sufficient for their utilization in differential diagnosis of these two forms of the disease.
