  • Title: Metabolism of copper and zinc in the liver and bone of the perinatal guinea-pig.
    Author: Lui EM.
    Journal: Comp Biochem Physiol C Comp Pharmacol Toxicol; 1987; 86(1):173-83. PubMed ID: 2881715.
    Abstract:
    Hepatic copper concentration in the guinea-pig increased markedly during the second-half of gestation, attaining a maximum shortly after birth; thereafter, concentration declined rapidly during the neonatal period. Changes in perinatal hepatic copper concentrations paralleled the binding of copper to a cytosolic metallothionein-like component, and the loss of hepatic copper in the neonates coincided with increases in serum copper concentrations. Zinc concentrations of the perinatal liver were low and showed no dramatic developmental changes. The humerus showed striking increases in zinc concentration with gestational age, attaining peak concentration before term and a marked depletion of tissue zinc during the neonatal period.
