[Behavior of various energy-metabolism enzymes in the maternal venous and umbilical cord blood during labor complicated by threatened intrauterine asphyxia].

The activity of some enzymes of indirect metabolic rate in maternal and umbilical blood were measured in the cases of normal and complicated by the severe intrauterine foetal asphyxia labours. It is concluded that the severe foetal asphyxia caused by the umbilical conflict is reflecting in the changed levels of the majority of examined enzymes in the umbilical blood.
