“…In a recent study, McKay, Thom, and Gray (1968) have been unable to detect significant differences between the concentrations of IgG, IgA, IgM, and albumin in the umbilical cord plasma of healthy infants and of neonates who developed respiratory distress syndrome. The reasons for the disagreement between McKay et al and ourselves on this issue…”

In our initial study of newborn infants suffering from the respiratory distress syndrome (RDS) (Hardie, Heese, and Kench, 1965), it was found that affected infants had significantly lower serum concentrations of total proteins than normal premature infants, and that the relative and absolute concentrations of y-globulins, as determined by paper electrophoresis, were much diminished. These abnormalities were present in the cord blood and became more marked in the first 2 to 3 days.In that paper we suggested that the y-globulin deficiency could be due to either (1) defective placental transfer of y-globulins, or (2) excessive y-globulin katabolism by the affected fetus and newborn, or (3) an immune reaction taking place in the fetus and newborn involving the maternal y-globulins as either antibodies or antigens.With these possibilities in mind a more detailed and extensive investigation of the serum proteins in this condition is described.Clinical Material and Methods Subjects of the study were either normal premature infants or premature babies suffering from RDS. The mean gestational age of the normal premature infants for whom data were available (72 of the 88 in the series) was 33 9 weeks. All the RDS infants (33) were traced, and these had a mean gestational age of 35-2 weeks. The clinical criteria for diagnosis of RDS were as before (Hardie et al., 1965). They were the presence of at least two of the following features for which no other obvious cause could be found: (1) cyanosis; (2) rib recession; (3) expiratory grunting; (4) generalized oedema; and (5) a 'ground glass' opacity on x-ray of the lung fields with an air bronchogram.Where the patient presented with cyanosis and
