Abstract

The article presents the results of histological examination of a placenta of a goat when it is normal and in the pathology of stillbirth. The experiments were carried out at the Department of Morphology, Examination and Surgery of the Ural State Agrarian University. The study has been carried out with placentas from 10 goats, which at the time of delivery had healthy posterity and stillborn foetuses. The morphological changes in three components of the placenta were estimated: epithelium of chorionic villi, connective tissue component and vascular component. It was found that in pathological pregnancy there is shortening of chorion villi, proliferative activity of the epithelium, vacuolization and necrosis of the villi. Vascular reaction was shown in overgrowth of blood vessels, mass diapedesis of red blood cells, endothelial cell exfoliation. From the side of the connective tissue component with stillbirth there were edema of the villous stroma and migration of polymorphonuclear leukocytes. Active perivascular reaction of mast cells was revealed.
