Activities of some peptidases and glycolytic enzymes in cells of the amniotic fluid. II. Pregnancies complicated by threatening intrauterine fetal asphyxia.
Activities of leucylaminopeptidase, aspartyl aminopeptidase, gamma-glutamyl transpeptidase, oxytocinase, phosphohexoisomerase, phosphofructokinase and aldolase were studied in amniotic cells from cases of pregnancy complicated by threatening intrauterine fetal asphyxia. Leucylaminopeptidase and oxytocinase activities were much higher in the group of pregnancies complicated by threatening fetal asphyxia than in the control group. It was concluded that elevated activity of the aforementioned enzymes in cells of the amniotic fluid from pregnancies complicated by threatening intrauterine asphyxia is due to acute hypoxia of the fetus.
