Kininase I was positively correlated with the S/D ratios, whereas placental leucine aminopeptidase (P-LAP) and aminopeptidase A were negatively correlated with the S/D ratios. It is known that the increased S/D ratios reflect the increased utero-placental blood flow resistance. Since our previous study showed that placental aminopeptidases degrade vasoactive peptides such as oxytocin, angiotensin and bradykinin, which the fetus actively produces, our present study suggests that the increased vascular resistance in feto-placental circulation in pre-eclampsia is partly controlled by changes in vaso-active peptides, via degradation by placental aminopeptidases., 名古屋大学博士学位論文 学位の種類 : 博士(医学)(論文) 学位授与年月日:平成4年7月20日 淺田義正氏の博士論文として提出された}, school = {名古屋大学, NAGOYA University}, title = {Relationship Between the Changes in Placental Blood Flow Resistance Assessed by Doppler Technique and Maternal Serum Placental Aminopeptidases, which Degrade Vaso-Active Peptides, in Pre-Eclampsia}, year = {1992} }
