Abstract

Melamine can be transferred to fetus in utero through placenta and to infant ex utero by breast feeding. In this study, we characterized the pharmacokinetics of melamine in prenatal and postnatal organs in rats. Single bolus of melamine was administered to pregnant rats at different gestational stages and to infants at different postnatal stages. Distribution of melamine in maternal serum was about 30% higher in late pregnancy than that in early pregnancy; and it was 2 folds higher in postnatal serum in early infants in young adulthood. Distribution of melamine in all postnatal organs was higher than that in prenatal organs. Postnatal kidneys in early infants had the highest maximum concentration and the lowest clearance of melamine than the other postnatal organs. It may relate to the high vulnerability to the toxicity of melamine in this population.
