Effect of Vitamin B12 and Aureomycin Supplements on Vitamin B12 Liver Stores and on the Development of Anemia in Gastrectomized Rats

Abstract
Ninety days after operation, the vitamin B12 liver content of gastrectomized rats was found to be greatly reduced when compared to that of non-operated animals. The moderate anemia present in the gastrectomized animals could not be corrected by giving vitamin B12 either orally or by injection. Vitamin B12 administered in conjunction with folic acid or a hog stomach preparation as a source of intrinsic factor likewise had no effect in preventing the development of the anemia. However, hemoglobin values were found to be within the normal range in gastrectomized rats fed a supplement of Aureomycin. There was no apparent increase in vitamin B12 liver stores of the antibiotic-fed gastrectomized animals.
