[Correlation of the parameters of zinc metabolism in lactating women and their infants 1 month after delivery].

Altogether 29 lactating mothers and their children were examined one month after the delivery in order to study zinc metabolism in lactating women living in Central Kazakhstan and in their children one month after the delivery and to determine interrelations between zinc metabolism in the mother and neonate, zinc concentration in breast milk and other parameters of zinc metabolism. One month after the delivery the lactating women manifested a rise of zinc content in blood plasma up to the lower limits of normal, the lasting increase of zinc content in red blood cells and the lowering of trace element concentration in the hair. A positive nonlinear relationship was found between zinc content in red blood cells and in mothers' milk as were a positive nonlinear relationship between zinc content in red blood cells of the lactating mothers and their children's hair and a negative linear relationship between trace element concentration in the hair of the mother and child.
