Serum copper and zinc values compared with serum iron, total iron-binding capacity, and transferrin saturation in sickle cell trait : A preliminary report

Zinc, copper, and magnesium concentrations in hair of children from southeastern Turkey

Zinc, copper, and magnesium concentrations in hair were measured in groups of children varying in one condition--protein-energy malnutrition, ricketts, thalassemia, malignancy, cardiac failure, or after prolonged infection and in healthy controls. As compared with controls, copper and magnesium concentrations were low in all groups, whereas higher values were obtained for hair zinc. These results showed that a generalized copper and magnesium deficiency were observed in the southeastern part of Turkey. However, zinc deficiency couldn't be detected as far as the hair zinc values were concerned, although all of the subjects fell within the 50 percentile limits for their age-appropriate weights and heights.
