Electrical potential difference across the mid-term human placenta.

Electrical potential difference across the mid-term human placenta was recorded during hysterotomy. The average value registered was 2.7 mV (S.E. of mean=0.4 mV, n=7), fetus negative. From this value and the concentrations of Na, K, Ca, Cl and inorganic phosphate in maternal and fetal plasma the possible mechanisms of net transport from mother to fetus are inferred. It is concluded that of the above ions only the transport of Na is compatible with simple diffusion.

Screening of amino acid enzymopathies in pregnancy and possibilities of their prenatal diagnosis.

The report discusses the first results obtained by chromatographic screening of the blood amino acids in pregnant women at the outset of pregnancy. Typical cases of maternal phenylketonuria and maternal hyperphenylalaninaemia found among 2,000 women examined are described in detail, giving a concise metabolic, clinical and genetic picture. The biochemical possibilities of diagnosing congenital disorders of amino acid metabolism before birth are also discussed.
