[Growth retardation and amino acids. Analysis of maternal plasma and amniotic fluid].

We have carried out an analysis of the amino acids in the mother's plasma and in the liquor amnii of 26 pregnant women who delivered either normal premature babies or those with intra-uterine growth failure. The levels found at delivery showed no difference in cases of prematurity in the composition of the substances in the plasma, but the liquor is poor in glycocol (GLY), Tyrosine (TYR), Phenylalanine (PHE). In the case of growth failure a significant drop in the concentration of Threonine (THR), Alanine (ALA), Valine (VAL), Methionine (MET) and Arginine (ARG) was found in the plasma. The liquor amnii however had shown no change in composition.

[Low serum thyroxin and thyroxin-binding globulin in neonatal respiratory distress (author's transl)].

Measurements of thyroxin (T4), thyroxin-binding globulin (TBG) and TSH were carried out in 34 full-term newborns, 21 prematures and 11 neonates with respiratory distress (6 with hyaline membrane disease) at 5 days of age. In cases with neonatal respiratory distress and to a lesser extent in prematures, low T4 due to a decrease of TBG was found, TSH being identical in all groups. The positive correlation between TBG and transferrin suggests a disturbance in hepatic synthesis. The authors conclude that, in cases with neonatal respiratory distress, low T4 does not mean hypothyroidism and does not require a treatment, provided TSH remains within normal limits.
