[Amino acid determination in amniotic fluid and plasma during normal pregnancies and suspected intrauterine growth retardation].

Report is made on the determination of 14 amino-acids in amniotic fluid and maternal plasma with normal pregnancy and with the presence of a fetal growth retardation. Mean values of 9 amino-acids determined in amniotic fluid with pregnancies and with a nutritive placental insufficiency are blow the mean values with normal pregnancies. These investigations are deemed as preliminary for treating small-for-dates fetus by injections of amino-acids into the amniotic sac.
