title: Collagen of umbilical cord vein and its alterations in pre-eclampsia.
abstract: The state of the vascular system of the mother and of placenta is known to exert a great influence on intrauterinal development of the fetus. Pre-eclampsia is the most common pathological syndrome connected with pregnancy. Since collagen is one of the main constituents of the vessel wall a comparison was made with collagen content and its molecular polymorphism in umbilical cord veins of newborns from healthy and pre-eclamptic mothers. It was found that umbilical cord veins of newborns from mothers with pre-eclampsia contained 18% less collagen than those of the newborns from normal pregnancies. This decrease was accompanied by a slight decrease of collagen solubility, but all its types (I, II, IV, V and VI) were present. However, the umbilical vein wall of newborns from mothers with pre-eclampsia contained relatively less of type I and more of type III collagen than the normal umbilical cord. These differences may be connected with a disturbance of blood flow in fetus of a woman with pre-eclampsia.
