Isoenzymes of N-acetyl-beta-hexosaminidase in complicated pregnancy

The activity of N-acetyl-beta-hexosaminidase was found to be significantly higher in the placentas collected after delivery from women in puerperium w ith symptoms of prolonged pregnancy or complicated by EPH gestosis, than in placentas from normal pregnancy. Isoelectrofocusing of placenta homogenate s showed the presence of isoenzymes A, P and B of N-acetyl-beta-hexosaminid ase. Different isoenzyme A patterns in homogenates were observed in placent as obtained from normal and prolonged pregnancies and in those complicated by EPH gestosis.
