| Abstract |
Cu absorption after Fe or Zn depletion was measured in vitro with everted sacs of rats. The experimental animals were depleted with a casein diet low in Fe or in Zn. The Cu transfer to the serosa solution of anemic intestines remained unchanged compared with that of Fe-supplied intestinal segments; only after Cu depletion the Cu transfer was 50-80% higher. In Zn deficiency the Cu transfer to the serosa solution, as well as the Cu uptake by the intestinal wall, was clearly elevated (P < 0.001). Since after Zn depletion the Zn absorption was elevated about threefold, possible interactions between zinc and copper in the uptake and transfer of these trace elements are discussed. |
