title: Effect of zinc on lead-induced changes in brain lysosomal enzymes in the chick embryo.
abstract: 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.
