title: Iron absorption in experimental uremia.
abstract: Gastrointestinal absorption of radioactive iron (59Fe) was studied in uremic rats. Duodenal gut sac transport of 59Fe in a group of 12 rats with a mean BUN of 98+/-24.4 mg%, was 2.29+/-1.16. This was significantly lower (p less than 0.01) than the amount of 59Fe transported (4.88+/-1.87) across the duodenum of a group of control rats, mean BUN 22.9+/-3.2 mg%. We conclude that there is diminished absorption of iron in uremia.
