Abstract
Erythrocytes from two dogs were labeled with about 100 μc of Cr51 (sodium chromate) and were returned to the blood of the dogs. Portions of blood withdrawn
later were placed in each dog's stomach and the subsequent radioactivity of the feces
was determined. By comparing this with the radioactivity of the blood, it was possible
to express the amount of Cr51 in the feces as the equivalent of circulating blood in milliliters. The amount of
Cr51 recovered paralleled closely the amount contained in the blood administered to the
dogs.
Additional studies on dogs and rats gave little indication of significant transfer
of Cr51 from labeled erythrocytes between the blood stream and the intestine.
