Strain difference of cadmium accumulation by liver slices of inbred Wistar-Imamichi and Fischer 344 rats.

Strain difference in the accumulation of cadmium (Cd) by liver slices was examined in inbred Cd-resistant Wistar-Imamichi (WI) and Cd-sensitive Fischer 344 (F344) rats. The accumulation of Cd by liver slices of WI rats was significantly lower than that of F344 rats, suggesting strain-related differences in the transport of Cd into the liver cells of these two rat strains. In addition, a similar strain difference was observed in the accumulation of zinc (Zn) by liver slices from WI and F344 rats.

A possible mechanism of resistance to cadmium toxicity in male Long-Evans rats.

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.

Strain differences of cadmium-induced hepatotoxicity in Wistar-Imamichi and Fischer 344 rats: involvement of cadmium accumulation.

We previously reported that Wistar-Imamichi (WI) rats have a strong resistance to cadmium (Cd)-induced lethality compared to other strains such as Fischer 344 (Fischer) rats. The present study was designed to establish biochemical and histological differences in Cd toxicity in WI and Fischer rats, and to clarify the mechanistic basis of these strain differences. A single Cd (4.
