The levels of calcium and magnesium, and of selected trace elements, in whole blood and scalp hair of children with growth retardation.

Objective: Metals such as copper (Cu), zinc (Zn), iron (Fe) are essential for human beings. Chronic metabolic disturbances may result from an excess or deficiency of these metals. Ca and Mg are also nutrient elements and play an important role in biological systems.

Comparison of the concentration of trace metals (Ni, Zn, Co, Cu and Se), Fe, vitamins A, C and E, and lipid peroxidation in patients with prostate cancer.

The anticarcinogenic and antioxidant properties of vitamins A, C, E and pro- or antioxidant properties of trace metals have recently attracted increased attention. We examined the levels of antioxidant vitamins (A, C and E), selenium and malondialdehyde (MDA), and trace metals (Fe, Ni, Zn, Co and Cu) in patients with prostate cancer. In total, 41 subjects (21 controls and 20 prostate cancer patients) were included in the study.
