[The flow cytometry of lymphocyte deoxyribonucleic acid in chronic lympholeukemia]. 1993

E T Dudko, and L M Tishchenko, and A K Kalinovskiĭ, and V B Krivozubov

A study of 140 patients with B-cell chronic lympoheucosis using flow cytometry of DNA of lymphocytes evidences an interrelation between the severity of the clinical course of the disease and state of lymphocyte DNA. The authors propose to distinguish 2 variants of chronic lympholeucosis: accumulative and proliferative. In the former DNA ploidy and kinetics of tumour lymphocytes did not differ from that in the healthy; in the latter--progression of the disease depended on S-phase lymphocyte contact. Progression of the severity of chronic lympholeucosis is accompanied by marked increase of polyploid cell in the S-phase that may be a criterion for early diagnosis of malignant transformation of chronic lympholeucosis.

UI MeSH Term Description Entries
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age

D004273 DNA, Neoplasm DNA present in neoplastic tissue. Neoplasm DNA
D005260 Female Females
D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.
