Blood and Fingernail Copper (Cu) and Magnesium (Mg) Levels of Children With Acute Lymphoblastic Leukemia

In this study, serum and fingernali Cu and Mg levels of 10 children with acute Iymphoblastic leukemia and 12 healthy chil- dren were determined. Copper and magnesium levels of the sera and supernatants were measured by atomic ab- sorption spectrophotometer. (Perkin-Elmer 400). Fingernail Cu and Mg levels of the patients were 8.67 ± 5.35 and 0.22 ± 0.12 µmol/mg of nail respectively. The values for control subjects were 4.27 ± 2.32 and 0.14 ± 0.03 µmol/mg of nail.
