چکیده
Page 1 of 6 http://sickle.bwh.harvard.edu/iron_absorption.html Figure 1. Iron absorption. Iron enters the stomach from the esophagus. Iron is oxidized to the Fe3+ state no matter its original form when taken in orally. Gastric acidity as well as solubilizing agents such as ascorbate prevent precipitation of the normally insoluble Fe3+ . Intestinal mucosal cells in the duodenum and upper jejunum absorb the iron. The iron is coupled to transferrin (Tf) in the revised January 11, 2001

INTESTINAL ZINC ABSORPTION IN DESFERROXAMINE-TREATED RATS
Desferroxamine (Desferal) is used tochelate iron in thalassemia, a disease of very high prevalence in various parts of lran. We have investigated intestinal zinc absorption in Desferal-treated rats which, in pilot experiments, showed low serum levels of both iron and zinc. Intraperitoneal administration of ten 0.5 g doses of Desferal (one injection every other day) to male rats produced sev...

متن کاملIron absorption is more closely related to iron status than to daily iron intake in 12- to 48-mo-old children.
Few studies have evaluated iron absorption in small children after the first year of life. Our objectives were to examine the relations among iron intake, iron absorption, and iron status in a group of healthy children. We studied 28 children, ages 12 to 48 mo, after a 7-d home adaptation to a diet representative of their usual daily mineral intake. A multi-tracer stable isotope study was perfo...
متن کاملFerritin iron absorption in man.
The iron absorption from ferritin and hemosiderin biosynthetically labeled with radioiron was studied in 108 subjects. The geometric mean absorption of ferritin iron in both normal and iron-deficient subjects was 1.9 percent. Its mean absorption ranged from 0.9 percent in normal subjects to 2.5 percent in subjects with moderate iron deficiency and 5.7 percent in subjects with marked iron defici...
متن کاملIron absorption in chronic renal disease.
1. Absorption of inorganic iron was studied in thirty-four patients with chronic renal failure by a double isotope technique. 2. Eight patients with normal iron balance had a mean absorption of 3-5%, ten patients with iron overload had a mean absorption of 3.6%, and sixteen patients with iron depletion had a mean absorption of 58%. Thus, alterations in absorption appeared to be related to distu...
متن کاملFood iron absorption in idiopathic hemochromatosis.
The relationship between iron status and food iron absorption was evaluated in 75 normal volunteers, 15 patients with idiopathic hemochromatosis, and 22 heterozygotes by using double extrinsic radioiron tags to label independently the nonheme and heme iron components of a hamburger meal. In normal subjects, absorption from each of these pools was inversely correlated with storage iron, as measu...
