title: [Action of heavy metal salts on the development of sea urchin embryos and on protein synthesis by the cells of transplantable mouse tumors].
abstract: Zu, Cu, Cd, Pb and Hg salts blocked the cleavage divisions in the sea urchin embryos and, in lesser concentrations, affected gastrulation and induced postgastrulation defects. The early embryo- and cytotoxic effects of Zn salts appear to be based on the inhibition of protein synthesis. Unithiol exerted a protective effect. All salts under study inhibited protein synthesis in the Ehrlich's ascite carcinoma and ascite hepatoma 22a cells; unithiol and other suldhydryl compounds exerted in this case a good protective effect against Cd salts only.
