title: DNA-protein cross-links in leukocytes of mice induced by Zn, Cd, and Pb.
abstract: A single subdermal injection of CdCl2 or Pb(CH3COO)2 results, together with remarkable changes in the blood cell pattern, in increased DNA-protein cross-links in mouse leukocytes in 24 h; after 15 days the DNA-protein cross-linking returned to the initial level. In contrast, after injection of ZnSO4 a high level of DNA-protein cross-links is retained during the whole observation period (15 days). In the studied range of doses the formation of DNA-protein cross-links is proportional to the logarithm of the dose.
