Gastro-Intestinal Blood Loss Measured by Radioactive Chromium

Radioactive Iron Absorption by Gastro-intestinal Tract

Iron absorption is a function of the gastro-intestinal mucosal epithelium. The normal non-anemic dog absorbs little iron but chronic anemia due to blood loss brings about considerable absorption-perhaps 5 to 15 times normal. In general the same differences are observed in man (1). Sudden change from normal to severe anemia within 24 hours does not significantly increase iron absorption. As the ...

The nature of anaemia in rheumatoid arthritis. V. Red Cell survival measured by radioactive chromium.

A number of studies have been undertaken to assess the importance of shortened red cell survival in the causation of anaemia complicating rheumatoid arthritis. Freireich, Ross, Bayles, Emerson, and Finch (1954), using the Ashby technique, found reduction of the life span of transfused erythrocytes from normal individuals in patients suffering from the disease. Alexander, Richmond, Roy, and Duth...

Loss of Gastro-intestinal-specific Antigen in Neoplasia.

Losso organspecific antigens has been shown to occur in epperimental and human carcinomas The present investigation, by serological and immunofluorescence methods, of a gastro-intestinal-specific antigen (Nairn et al., 1961; Nairn, 1962b) in human gastro-intestinal neoplasia demonstrates that loss of antigen is a feature of colonic and gastric carcinomas. Lesser degrees of depletion are found i...

Gastro-intestinal Obstruction

M.D. (Pp. xii + 566; figs. 415. 144s.) London: Bailliere, Tindall & Cox, 1958. THIS work covers every conceivable aspect of obstruction in the gastro-intestinal tract from the cesophagus to the anal canal in a truly encycloprdic manner. The book contains a tremendous amount of information and approximately 1,700 references in the bibliography. It is refreshing here to note that the authors incl...
