In mice fed a low iron diet, the addition of low levels of cadmium chloride (10 micrometer) to the drinking water impaired growth and accentuated the development of anemia. Cadmium had no effect on mice given a similar diet supplemented with iron. Iron deficiency increased the concentration of cadmium in the duodenal mucosa, the transfer of cadmium to the(More)
The serum ferritin concentration was measured in 1417 Indians and 310 Inuit aged 1 to 89 years. The subjects were initially selected to produce a representative sample of the entire native population, but the rate of nonresponse was high, and the results reported in this paper are representative only of the people studied.In males the median serum ferritin(More)
Dietary iron deficiency enhances the absorption of iron, cobalt, manganese, zinc, cadmium and lead, whereas, iron deficiency due to bleeding increases the absorption of iron, cobalt and perhaps manganese. To determine whether the response to bleeding is qualitatively different from that induced by dietary iron deficiency, metal absorption was studied in(More)
In protecting the body against the noxious effects of dietary cadmium ions, cadmium is bound to metallothionein in the proximal intestine, and subsequently excreted into the lumen with desquamation of the epithelium. The purpose of this study was to determine the extent to which cadmium in the form of intestinal cadmium-thionein is absorbed from the(More)
Zinc absorption, endogenous luminal zinc and intestinal metallothionein were examined in rats and mice fed zinc-deficient and zinc-replete diets for 5-7 days. Small intestinal luminal washings from undosed rodents fed the replete diet contained 18- to 20-fold more zinc than those from zinc-deficient animals. Isotope dilution by this endogenous zinc could(More)
Isogeneic intestinal transplantation of iron-loaded and iron-deficient intestine into iron-deficient rats was performed in 20 Lewis rats to isolate the effect of intestinal mucosal iron on iron absorption. Rats were iron loaded with three weekly IM injections of 50 mg of iron dextran and were rendered iron deficient with an iron-deficient diet for 3 weeks.(More)
Duodenal uptake and transfer of 59Fe and 65Zn and absorptive interactions between iron, zinc, cobalt, and copper were studied in sla mice and in genetically normal Swiss albino control mice. Genetically normal mice with a high iron-absorbing capacity, induced by being fed an iron-deficient diet, showed greater uptake and transfer of 65Zn in duodenum but not(More)
