[The determination of buccal epithelial cells in forensic medical cytological research].

The morphology of isolated cells of multi-layer squamous non-horny epithelium (buccal, vaginal, urethral, rectal), stained with 0.05% nigrosine solution, was under study, and the sizes of these cells and their nuclei were measured. Specific markers were detected in the buccal epitheliocytes, that permit their reliable differentiation from other epitheliocytes studied by the size of the cells and nuclei, by a characteristic structure of the cytoplasm, etc. The findings may be used for the diagnosis of the origin of isolated cells of the buccal mucosa.
