Morphometric and immuno-biochemical markers of placenta in patients with uterine eclampsia

Abstract

Purpose: to study the segmentation of organometric and immuno-biochemical digital indicators in ewes with ESO at the end of gestation.Materials and methods. The experiment involved three flocks of Tsygai, Volgograd and Stavropol breeds, each with 700 suyag sheep. Placental tissue samples were taken from clinically healthy and sick pregnant ewes, which were placed in 10% neutral formalin. Using a Cytadel 2000 histoprocessor (Shendon), the obtained samples were clarified in chloroform and enclosed in a Histomix paraffin medium (Biovitrum). Histosections were prepared on a rotary microtome (MICROM HM340E). Using the AxioScope.A1 (ZEISS) microscope, histopreparations were photographed and processed using the ZENpro 2012 (ZEISS) program. According to Schmidt and Thannhauser, the RNA content was determined using a two-wave spectrophotometer in UV. The activity of the G-6-Phase was studied by Swanson. In vacuum tubes Vacuette ™ (Austria), blood samples were taken in the morning before feeding, from the jugular vein. Results. In sheep with eclampsia, a decrease in the total mass of the placenta, its cotiledons, as well as an increase in the length of the umbilical cord, in which stroma sclerosis is noted in the vascular wall, was observed. Small calcification foci were found in the tissues of the afterbirth, and small terminal villi are located around the stem villi near the vascular membrane, tightly adjacent to them. The proportion of syncytiotrophoblast of crypts of carbuncles and villi of the chorion of cotyledons of mature syncytium decreases in comparison with physiologically occurring severity. The content of RNA in its subcellular fractions is mainly concentrated in the microsomal fraction, 18% - in mitochondria and 7% - in the nuclear fraction. Albumins in pregnant ewes with eclampsia were reduced by 1.35 times. BASC and phagocytic activity of leukocytes in queens with eclampsia of pregnant sheep is reduced 15 days before lambing, which poses a threat to the reproductive health of the mother and the viability of newborn lambs.
