title: Intestinal calcium absorption: nature of defect in chronic renal disease.
abstract: When compared to that of normal animals, calcium-binding protein activity of duodenal mucosa obtained from uremic rats was decreased. There was no change in this activity after vitamin D(3), therapy. In contrast, prior treatment with 25-hydroxycholecalcijerol resulted in increased transport of calcium-45 and calcium-binding protein activity in the intestine.
