The interaction of injected zinc salts (Zn) and cadmium salts (Cd) with regard to the synthesis of metallothionein (MT) in adult rat liver was investigated. Male rats received an i.p. injection of Zn (20 mg/kg) or Cd (0.6 mg/kg) with or without pretreatment with Zn (20 mg/kg 16 h prior to the second injection). It was found that both metals, when administered singly, induced the synthesis of significant levels of hepatic MT, but that, when the Cd injection followed the Zn injection, synthesis of MT was not additive. When Zn pretreatment was followed by a second Zn injection, MT accumulation was additive (approx. 2-fold of that observed after a single Zn injection). Also, a highly significant positive correlation, (r = 0.97, P less than 0.01) was noted between hepatic Zn concentration and hepatic MT concentration, a relationship which was independent of the mode of MT induction. The results of the investigation indicate that: (1) in the presence of pre-existing hepatic Zn--MT, the ability of Cd to induce new MT synthesis is greatly reduced; rather, Cd is sequestered by the pre-existing MT; and (2) Zn may play a major role in the induction of MT synthesis both after Zn administration and after Cd administration.
