[Use of micronuclear test to the human buccal mucosal epithelium].
The paper presents microphotos of anomalies of the human buccal mucosal epitheliocytic nucleus and gives criteria for their identification. Two procedures for making a scrape from the buccal mucosa were compared. The smears prepared from the samples taken with a urogenital brush showed the lower frequency of cells with micronuclei, protrusions of the "broken egg" and "tongue" types, vacuolated cells, as well as cells with nuclear pyknosis and lysis than those prepared with a rough scrape spatula. The nuclear frequency of cells with condensed chromatin in such smears was higher than that in the rough scrape. In addition, the authors show a relationship of the frequency of cells with the binuclei, perinuclear vacuole, nuclear pyknosis, and condensed chromatin in the nucleus, and absorbed apoptotic (residual) bodies to the examinee's age.
