Abstract

The cytoxicity and the 50% lethal concentration (LC50) has been assessed in vitro by the colony forming method in extracts of 5 precious or semiprecious alloys and of oxides and chlorides of the metal contained in these alloys: Pd, Ag, Cu, Zn, Sn, In and Ga. All alloy extracts in culture medium induced cell death depending on their composition. In, Ga and Sn compounds showed the most favorable cell viability, Cu and Ag salts induced the lowest survival rate.
