Abstract/OtherAbstract:
The susceptibility to cadmium (Cd)-induced toxicity in male Long-Evans (LE) rats was compared with that in male Fischer 344 (Fischer) and Wistar-Imamichi (WI) rats, which are sensitive and resistant, respectively, to Cd toxicity. All rats of the LE and WI strains survived for 7 days after the treatment with a toxic dose of Cd (6.5mg/kg b.w.). However, all rats of the Fischer strain died by the following day. The strong resistance to Cd toxicity in the LE strain was confirmed to be independent of metallothionein synthesis induced by Cd. The hepatic and renal Cd contents after its administration were significantly lower in the LE strain than in the Fischer strain. Furthermore, the hepatic and renal zinc (Zn) contents after its administration were significantly lower in the LE strain than in the Fischer strain. These limited data suggest that the strong resistance to Cd toxicity in male LE rats results from, at least in part, the lower accumulation of the metal in the liver and kidney, in a similar mechanism as the lower Zn accumulation.
