Abstract
The ratio of the plasma concentration of glycing + serine + glutamine + taurine to the concentration of leucine + iso-leucine + valine + methionine has been studied by Whitehead's method using paper chromatography. The mean postanatal rise in the ratio was foound to be significantly higher than that observed previously in infants born to mothers with uncomplicated pregnancies. The higher ratio observed in the different series of examinations was due to a pronounced opposite response in the plasma level of the two groups of amino acids included in whitehead's ratio test. The results will be discussed in relation to conditions interfering with uteroplacental funtions.
