[Serum zinc dynamics in chronic renal insufficiency treated with periodic hemodialysis].

Serum zinc concentration and the effect of dialysis was followed up in 35 patients with chronic renal insufficiency, included in the programme dialysis treatment. Zinc level, at the end of dialysis was established to be elevated, being explained by the high zinc concentration in fountain water, with which the dialysis solution was prepared. Owing to the fact that the elevated values of serum zinc are included in the normal region, the authors think that no deionization of water is necessary aiming at the reduction of zinc concentration in it.
