Relationship between the changes in maternal serum placental leucine aminopeptidase (P-LAP) activity and umbilical artery waveforms in normal pregnancy.
The relation between placental leucine aminopeptidase (P-LAP) activity in maternal sera and umbilical artery waveforms (systolic/diastolic ratio, S/D) obtained by pulsed Doppler has been examined by cross-sectional study in 26 normal pregnancies during weeks 26-38. A negative correlation was seen to exist suggesting that P-LAP may have a role in the regulation of uteroplacental blood flow.
