[Morphometric analysis of lymphocyte nuclei in chronic lymphocytic leukemia]

This work is dedicated to the study of use of quantitative analysis of cell nucleus structure for the analysis of peripheral blood lymphocytes in patients with chronic lymphocytic leukaemia. The structure of lymphocytic nuclei of healthy donors was evaluated by means of staining by toluidine blue purified cell suspensions smears. The preparations were analysed on the television measuring system "omnicon" with measurements of the following parameters: square of the nucleus, euchromatin, heterochromatin, and the ratio of heterochromatin and euchromatin squares. Actuarial analysis and nuclei classification of the previously mentioned parameters showed, that in peripheral blood of patients with chronic lymphocytic leukemia a large amount of atypical lymphocytes is present with reduced nucleus sizes. Atypical cells retain the ratio of structural components of chromatine, characteristic to normal cells, which show their low proliferative activity.
