The studies were performed on 12 placentas from pathological pregnancies (gestosis, cholestasis, type A diabetes pregnancies, premature outflow of amniotic fluids) and 3 placentas from normal pregnancies. Ultrathin sections were stained by the Reynold's method and evaluated under the electron microscope BS-500 (Tesla). The changes found in syncytiotrophoblast were the following: the increase or the decrease in its thickness, increase in basal membrane thickness, decrease in the number or lack of pinocytic vesicles and superficial microvilli, damage of mitochondria.
