Plasma samples from human cord blood, and fetuses, newborns, and adults of different mammalians species were analyzed by gel-filtration chromatography, to ascertain whether gamma-glutamyltransferase (GGT) fractions reflect liver maturation. Human cord blood plasma showed higher b-, m-, and s-GGT fraction as compared to adult women. In rat and mouse fetuses and in newborns, b-GGT was the most abundant fraction. As in adult humans, in adult rats, mice, rabbits, sheep, and mini pigs, f-GGT was the most abundant fraction. GGT fractions are a common feature of all mammalian species tested. Their pattern changes seem to reflect liver postnatal maturation, function.

Abstract
Plasma samples from human cord blood, and fetuses, newborns, and adults of different mammalians species were analyzed by gel-filtration chromatography, to ascertain whether gamma-glutamyltransferase (GGT) fractions reflect liver maturation. Human cord blood plasma showed higher b-, m-, and s-GGT fraction as compared to adult women. In rat and mouse fetuses and in newborns, b-GGT was the most abundant fraction. As in adult humans, in adult rats, mice, rabbits, sheep, and mini pigs, f-GGT was the most abundant fraction. GGT fractions are a common feature of all mammalian species tested. Their pattern changes seem to reflect liver postnatal maturation, function.| File | Dimensione | Formato | |
