[Physico-chemical characteristics of the plasma membrane of the human placenta in placental insufficiency].

Lipid peroxidation, microviscosity, lipid fraction ratios and glycoprotein carbohydrate metabolism were investigated in syncytiotrophoblastic plasmatic membranes of patients with placental insufficiency. Changes are demonstrated in the above parameters, as compared to normal values, indicative of profound structural transformations of placental membranes. Hyperbaric oxygenation is shown to have a favorable effect on structure and properties of placental membranes.
