Iron Absorption in Experimental Uremia

Abstract
Gastrointestinal absorption of 59Fe was studied in uremic rats. Duodenal gut sac transport of 59Fe in a group of 12 rats with a mean BUN [blood urea nitrogen] of 98 .+-. 24.4 mg%, was 2.29 .+-. 1.16. This was significantly lower (P < 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%. There was diminished absorption of Fe in uremia.
