At low levels of dietary cadmium chloride, cadmium accumulates directly in the kidneys and not in the liver. As dietary cadmium induces intestinal metallothionein (MT), intestinal CdMT complexes could be at least partly responsible for the renal accumulation of oral cadmium. For this to be possible, however, serosal release of mucosal CdMT would be required. To test this hypothesis, we perfused isolated rat small intestinal segments (Fisher-Parsons method) in an attempt to demonstrate the release of intestinal MT. After two weeks of feeding dietary cadmium chloride, intestinal MT was induced in amounts proportional to the dietary cadmium level. Subsequent in vitro perfusion of the small intestine revealed a concentration-dependent release of intestinal MT on the serosal side. When 109CdCl2 was present in the perfusion medium, 109Cd appeared on the serosal side mainly in the MT fraction. These results indicate that endogenous intestinal MT may deliver CdMT to the organism, thus possibly contributing to the renal accumulation of orally ingested cadmium.
