Abstract:
The micronucleus (MN) level in exfoliated buccal mucosa cells of women with marked hirsutism (WH) was studied. Other nuclear anomalies such as karyorrhexis, karyolysis, pycnosis, binucleates and condensed chromatin were also investigated. As control, buccal mucosa cells of healthy women of corresponding ages were studied. The results showed that in the cells of WH the frequencies of MN and cells with MN were increased compared to controls. The nuclear anomalies were at the same level as in controls.
We suggest that the evaluation of MN in exfoliated buccal mucosa cells can represent endogenous mutation process in organism of WH as earlier it was shown for chromosomal aberrations in lymphocytes. Consequently, WH should avoid contact with mutagens because of genetic instability in somatic cells and therefore should have restriction for some kind of work.
