In recent years, a leading role in placental development disorders vascular factors is given, which leads to an imbalance of placental insufficiency.
It has been studied 20 placentas from women after assisted reproductive technology with non-alcoholic fatty liver disease and 20 placentas from women after assisted reproductive technology without liver disease (control group).
Methods: organometrical, macroscopic, general histological and immunohistochemical: indirect streptavidin-peroxidase method of detecting the expression of e-NOS (endothelial nitric oxide synthases) level, antibody Thermo Scientific Company (UK) on the manufacturer’s protocol. The prevalence and intensity of the reaction was assessed by semiquantitative method on a scale from 0 to 3 points.
According to study results, in women with liver pathology after assisted reproductive technology observed increase in placental weight. In 50% of placentas marked foci relative immaturity of the dissociated cotyledons type, poor circulation on the background of compensatory reactions of moderate severity. Morphometric observed with single dominance of villous capillaries, which are located centrally, which leads to a significant reduction in the number syncytiocapillary membranes and reduces specialized terminal villi, in violation of the permeability of the placenta. Significantly increased the number intervillous and fetal fibrinoid, glued fibrinoid villi, syncytial knots, heart attack, reduced intervillous space and the bloodstream, thinned epithelium villi, increased compensatory angiomatosis vessels. These changes reflect the impaired circulation and permeability of the placenta, impair its functionality and are the pathological background against which develop obstetric and perinatal disorders.
The study authors conclude that the absence or reduction of e-NOS expression in the most functionally important structures in the majority (60%) placentas of women with hepatobiliary pathology induced during pregnancy, indicating a lack of compensatory reaction, endothelial dysfunction, macro- and microcirculations processes and, as a result, decrease of placental functional capabilities.
