    Hormonal disorders are one of the main known causes of miscarriage and preterm birth in multiple pregnancies resulting from assisted reproductive technology (ART). Progesterone and the number of its receptors play an important role in the preservation and prolongation of pregnancy and it is the pressing issue of our time. The study of placentas, as the main site of synthesis of progesterone, has high informative potential and it is the most important diagnostic object, and information received by its research is essential for the full conclusion on the causes, mechanisms, close and long-term effects of multiple pregnancy pathology. Aim. The aim of our study was to investigate immunohistochemical features of placentas from women with dichorionic diamniotic twin pregnancies in spontaneous fertilization and after use of assisted reproductive technology (ART). Methods and results. According to this goal we examined 94 women, 44 of whom had multiple pregnancies due to ART, 42 with separate multiple pregnancy and 38 women with a singleton pregnancy. We carried out clinical and statistical analysis of the course of pregnancy and childbirth in the studied groups. During the study it was found that multiple pregnancies due to assisted reproduction belong to the high risk of gestation, at which premature births occur much more frequently than in singleton pregnancies. We were the first to carry out the immunohistochemical study of placentas in which the highest expression of progesterone receptors in the nuclei of cells of decidua (45%) related to the parent structure of the placenta from women with multiple pregnancies caused by ART is found. It is also found that with increasing gestational age, there has been a significant decrease in the expression of the activity of progesterone receptors (from 45 to 2.5%), regardless of the method of conception and the number of fetuses. Conclusions. The results of the study point to the definitive link of structures of placental-endometrial relations as an important component of the appropriateness of hormone therapy

    Aim. Researchmaterials were the placenta of women operated on papillary carcinoma (encapsulated), endometrium of women with the same tumor markers detected in the placenta, this endometrium were taken during diagnosing postpartum catamnesis of the state of reproductive health, in comparison to the endometrium of women with benign uterine tumors (leiomyoma).Methods and results. Methods, that were used in the study: histological, immunohistochemical – indirect streptavidin-peroxidase method for detecting the expression of Ki67 Clon MIB-1, p53 Clon: DO-7, REA, Cytoceratina AE1 / AE3; Vimentin Clone: v9, receptors for estrogen (RE) and progesterone (RP). The study evaluated predictors of placental-endometrial disorders in women with cancer pathology: elevation of relative amount of expression of proliferative marker Ki-67 and p53 tumor marker in the placenta and endometrium, leading to violations in the structure of the process of regeneration; dischronosis in levels of expression of estrogen and progesterone receptors in the endometrium; presence of CEA expression in 25% of women of the main group in the endometrium and placenta; atypical glandular hyperplasia, endometrial polyps and micropolyps were found, which are important in the development of oncologic pathology.Π‘ Ρ†Π΅Π»ΡŒΡŽ опрСдСлСния ΠΏΡ€Π΅Π΄ΠΈΠΊΡ‚ΠΎΡ€ΠΎΠ² патологичСских состояний Π² ΠΏΠ»Π°Ρ†Π΅Π½Ρ‚Π΅ ΠΈ эндомСтрии ΠΆΠ΅Π½Ρ‰ΠΈΠ½, ΠΏΡ€ΠΎΠΎΠΏΠ΅Ρ€ΠΈΡ€ΠΎΠ²Π°Π½Π½Ρ‹Ρ… ΠΏΠΎ ΠΏΠΎΠ²ΠΎΠ΄Ρƒ Ρ€Π°ΠΊΠ° Ρ‰ΠΈΡ‚ΠΎΠ²ΠΈΠ΄Π½ΠΎΠΉ ΠΆΠ΅Π»Π΅Π·Ρ‹, Π²Ρ‹ΠΏΠΎΠ»Π½ΠΈΠ»ΠΈ ΡΡ€Π°Π²Π½ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΠ΅ исслСдованиС ΠΏΠ»Π°Ρ†Π΅Π½Ρ‚ ΠΈ эндомСтрия ΠΆΠ΅Π½Ρ‰ΠΈΠ½, ΠΊΠΎΡ‚ΠΎΡ€Ρ‹ΠΌ ΠΏΡ€ΠΎΠ²Π΅Π΄Π΅Π½ΠΎ ΠΎΠΏΠ΅Ρ€Π°Ρ‚ΠΈΠ²Π½ΠΎΠ΅ Π²ΠΌΠ΅ΡˆΠ°Ρ‚Π΅Π»ΡŒΡΡ‚Π²ΠΎ Π² связи с Π½Π°Π»ΠΈΡ‡ΠΈΠ΅ΠΌ папиллярной ΠΊΠ°Ρ€Ρ†ΠΈΠ½ΠΎΠΌΡ‹ (инкапсулированной), ΠΈ эндомСтрия ΠΎΡ‚ ΠΆΠ΅Π½Ρ‰ΠΈΠ½ с доброкачСствСнными опухолями ΠΌΠ°Ρ‚ΠΊΠΈ (Π»Π΅ΠΉΠΎΠΌΠΈΠΎΠΌΠ°).
