Effect of zinc on lead-induced changes in brain lysosomal enzymes in the chick embryo.
Administration of zinc (Zn) simultaneously with lead (Pb) into the chick egg yolk sac reduced the accumulation of Pb and Pb-induced alterations in the activities of acid phosphatase, beta-glucuronidase and ribonuclease in the brain of the embryo. The results suggest protection against toxic effects of Pb by Zn.
