Which sublethal cadmium pretreatment may prevent from lethal cadmium's killing mice and which cadmium pretreatment-induced protection against cadmium lethality to mice may be related with their hepatic glutathione contents were investigated. When cadmium chloride was subcutaneously injected to mice (ICR strain) at various doses, all mice died, which treated with cadmium at dose of 300 $\mu$moles/kg or more, and none died, which treated with cadmium at dose of 80 $\mu$moles/kg or less. Subcutaneous pretreatment of sublethal cadmium decreased sacrifice of mice which subsequently injected with lethal cadmium, with most effectiveness at pretreatment dose of cadmium of 40 $\mu$moles/kg b.w. and at 48 hours of interval between sublethal cadmium pretreatment and lethal cadmium treatment. Even if a great part of the cadmium-pretreated mice were sacrificed while treated with lethal cadmium, they survived longer than the non-pretreated mice. Sublethal cadmium pretreatment (40 $\mu$moles/kg b.w.) 48 hours before lethal cadmium treatment to mice didn't decrease hepatic glutathione contents of the survived mice, while decreases in the glutathione in livers were observed in the mice just after died. These results indicate that sublethal cadmium pretreatment-induced protection against cadmium lethality to mice may be related to their hepatic glutathione contents.
