SERUM GASTRIN I CONCENTRATIONS OF MOTHER AND NEWBORN IMMEDIATELY AFTER BIRTH

Abstract
Serum gastrin I [G] (Glu-Gly-Pro-Try-Leu (Glu)5-Ala-Tyr-Gly-Try-Met-Asp-Phe-CO-NH2) concentrations were investigated by radioimmunoassay in 50 mothers and their newborn infants immediately after birth. The mean serum G concentration in maternal blood was 52.80 .+-. 13.37 (SD) pg/ml, and in cord blood 84.12 .+-. 42.90 (SD) pg/ml. Both values were significantly higher than serum G levels found in normal, healthy, nonpregnant women (mean .+-. SD 32.34 .+-. 18.35 pg/ml). There were no statistically significant differences in the cord serum G concentrations with respect to sex, weight and length of the infant and age and parity of the mother.
