The article deals with modern views on etiopathogenesis of uterine fibroids. Increased knowledge of the markers of proliferation and their study will help to predict the course of the disease and thus to develop the optimum tactics of the further treatment of the early stages. Much attention is paid to the study of markers that characterize apoptosis. By immunohistochemistry in tissue fibroids 15 patients studied protein expression Ki-67 and Bcl-2. Analyzed values of the correlation expression of the proteins according to the clinical and morphological features of the tumor. It showed a reduction in the proliferation marker Ki-67, and increased expression of apoptotic Bcl-2 inhibitor.Background. Presented by changes in the nature of proliferation and apoptotic activity in myoma nodes among women of reproductive age who underwent conservative myomectomy.The aim of the research was to study the performance of protein antibody Ki-67 proliferation and apoptosis inhibitor of Bcl-2 in women with uterine myoma.Material and methods. Surveyed 15 women with uterine fibroids who underwent conservative myomectomy. Inclusion criteria were: the reproductive age, uterine fibroids the size of which does not exceed the 12-week pregnancy. Exclusion criteria were the size of fibroids greater than 12 weeks of pregnancy, acute inflammatory diseases of the pelvic organs, severe somatic diseases, cancer of the reproductive organs. It was carried out histological and immunohistochemical study of remote myoma node. We examined by immunohistochemistry proliferation protein monoclonal antibody Ki-67 (Clone MIB-1, 1 : 150, Dako), inhibitor of apoptosis Bcl-2 (NCL-bcl-2-486). (Novocastra). Evaluation of the expression of markers studied conducted qualitative and quantitative methods in computer image analysis system “Morphology 5.0” (Video Test, Russia). Statistical processing of the results was performed using statistical analysis packages (STATGRAPHICS v. 6.0).Results. Age of women surveyed averaged 33,4 ± 4,1 years. Histological study of benign tumors of the uterus body showed the presence of degenerative changes, necrosis and inflammatory infiltration in every fourth case of the material.Conclusions. Immunogistohimichesoe study of uterine leiomyomas body revealed a significant increase in the expression of apoptosis inhibitor of Bcl-2 and reducing the proliferation marker Ki-receptor expression in all 67 tested samples, which is consistent with a histological study of the absence of mitotic activity in leiomyomas.
