[Differences in concentration of free amino-acids in fetal and maternal compartments at the end of normal and pathologic pregnancies (author's transl)].
Free amino-acids in the fetal and maternal compartments towards the end of normal and pathologic pregnancies were examined with gas chromatography. Blood was obtained from the cubital and uterine veins and the femoral artery of the mother, from the umbilical artery and vein and the amniotic fluid during Caesarean section. There were only minor differences of concentration of free amino-acid between normal and pathologic pregnancies. Since it is possible in principle that there is mutual balance between maternal and fetal compartments, assessment of changes in amino-acid concentration during dia- and paraplacentar exchanges is usable only with reservations.
