Документ Morphometric analysis of placental and M1/M2 macrophages polarization in the detection of fetal growth restriction(Українська медична стоматологічна академія, 2021) Berezhna, V. A.; Gromova, A. M.; Mamontova, T. V.; Udovytska, N. O.; Starchenko, I. I.; Vesnina, L. E.; Бережна, Варвара Анатоліївна; Громова, Антоніна Макарівна; Мамонтова, Тетяна Василівна; Удовицька, Наталія Олегівна; Старченко, Іван Іванович; Весніна, Людмила ЕдуардівнаThe purpose of the present study was to analyzed the morphometric characteristics and CD68 and CD163 expression of macrophages in the placentas of women, whose pregnancies were complicated by fetal growth restriction. The study revealed low indices of the mass and area of the placentas, but high indices of the fetoplacental weight ratio. The level of CD68+ macrophages in fibrously altered terminal villi of the placenta was significantly higher in both groups women whose pregnancies were complicated by fetal growth restriction. There was significant increased CD163+ macrophages in fibrously altered terminal villi. Thus, in the placentas of women whose pregnancy was complicated by fetal growthrestriction and resulted preterm birth, there were disruptions of the vascular and stromal component of the chorionic villus with the changes to macrophage polarization from M1 to M2 types in fibrously altered terminal villi of the placenta.Документ Soluble endoglin as an early prediction marker of intrauterine growth retardation(2021) Gromova, A. M.; Berezhna, V. A.; Gromova, O. L.; Lyakhovska, T. Yu.; Ketova, O. M.; Громова, Антоніна Макарівна; Бережна, Варвара Анатоліївна; Громова, Олександра Леонідівна; Ляховська, Тетяна Юріївна; Кетова, Олена МиколаївнаHigh levels of circulating endoglin contribute to the development of endothelial dysfunction, which underlies the pathogenesis of intrauterine growth retardation and can be used as a prognostic marker for the development of this pathology. We collected serum from pregnant women with intrauterine growth retardation (n-41) initially at diagnosis and before delivery, and pregnant women with physiological pregnancy (n-8), using enzyme-linked immunosorbent assay to test soluble endoglin levels. It was found that the level of soluble endoglin concentration was 7.2±0.2 at the initial examination and 9.5±0.1 at the repeated examination in women who gave birth to low birth weight children with fetal developmental delay and constitutionally small children, while the level of this factor in women in the comparison group was 3.7±0.3. It was found that the level of soluble endoglin concentration was significantly higher in women who gave birth to children with intrauterine growth retardation than the level of this factor in women in the comparison group, which is highly informative to use its prognostic value.
