Iron, copper, and zinc in children from Tanzania afflicted with protein-calorie malnutrition]

Atomic absorption spectrophotometry was employed in an evaluation of zinc, copper and iron as trace elements in serum and erythrocytes from 56 children with protein-calorie malnutrition at different stages (early kwashiorkor, kwashiorkor and marasma). Iron and zinc concentrations showed a decreasing pattern through the various stages of the P.C.M. Significant changes are present in zinc values. The role of these trace elements in the P.C.M. is shortly discussed.
