Abstract

IT has been shown1,2, with the help of rabbit and sheep erythrocytes labelled with iron-59, that appreciable amounts of iron from hæmoglobin were absorbed when these cells were administered orally to human beings. So far as we know, no information is available on the re-absorption of hæm-attached iron from intestinal bleeding lesions. A method for measuring such a re-absorption is here proposed.
