Abstract | UNLABELLED:
Divalent cations ( calcium, magnesium, zinc, cooper, manganese) play an important role in various biological processes. Different acute or chronic renal disorders in children or adults modify the urinary excretion of these cations and may influence their concentrations in organism. AIM: Evaluation of the changes of some divalent cations levels (Cu, Zn, Mg, Ca) in acute renal diseases. MATERIAL AND METHODS: We measured plasma concentrations and urinary excretion of cations in pediatric patients with acute urinary infections. We also evaluated malondyaldehide (MDA) and total antioxidant capacity (TAC) plasma levels. RESULTS: The obtained results show that serum levels of Ca, Cu, Zn are decreased in patients with acute urinary infections compared with a control group of healthy children, while urinary excretion of Cu and Zn there were higher in group study compared with control group. There are no significant differences of the serum magnesium concentration. Increased plasma MDA levels and decreased plasma TAC, Cu and Zn concentrations indicate an increased oxidative stress in patients with acute renal diseases. CONCLUSIONS:
