Abstract

We studied morphological features of the buccal epithelium in female students in various phases of the menstrual cycle (proliferation and secretion) in the Belgorod region. The results showed that hormonal fluctuations lead to changes in the composition of the buccal mucosa. The prevalence of typical buccal epithelial cells is associated with a predominance of estrogen during the proliferation phase. Identification of leukocyte clusters and groups of horny scales points to morphological changes induced by progesterone in the secretion phase. An increase in the area of epithelial cell nuclei and cytoplasm in buccal mucosa as well as an increased nuclear and cytoplasmic index in the secretory phase, as compared with the proliferation phase, can be accounted for by enhanced synthetic activity of the cells induced by progesterone.

Keywords
