[Proteolytic activity of placenta with EPH-gestosis determined by casein and azocasein].

Total proteolytic activity, activity of cathepsin B, activity of cysteine cathepsins and contents of protein degradation products were determined in placentas of pregnancies complicated with mild, moderate and severe EPH-gestosis and in placentas from normal pregnancies. The highest activity of all the determined proteases was observed in placentas of pregnancies complicated with severe EPH-gestosis. The placentas of pregnancies complicated with severe EPH-gestosis also include the highest amounts of aminoacids and low-molecular peptides.
