Studies in Iron Absorption
P REVIOUS STUDIES showed that general systemic factors like the hemoglobin concentration, serum iron concentration, iron binding capacity, and the plasma iron clearance rate were not correlated to the intestinal iron absorption. Neither did parenteral iron treatment normalize high iron absorption.1 The purpose of the present study is to examine such local intestinal factors as the quantity and ...
متن کاملStudies on Iron Absorption. Intestinal Regulatory Mechanisms.
Recent studies (1-3) have indicated that gastrointestinal absorption of iron is a more complicated process than was initially postulated (4, 5). For example, several investigators have proposed as the result of studies in rats (2, 3), dogs (6), and humans (7) that iron absorption involves at least 2 steps: 1) mucosal uptake of iron from the intestinal lumen and 2) transfer of iron from mucosal ...
متن کاملUnderstanding iron absorption and metabolism, aided by studies of hemochromatosis.
Duodenal iron absorption from food is selectively blocked to prevent iron intoxication. The prime example of pathologic increase in intestinal iron absorption is seen in patients with hemochromatosis. They suffer iron damage to the heart, liver, and other tissues resulting in premature death if the iron is not removed by vigorous phlebotomy. Examples of overcoming the intestinal barrier to iron...
متن کاملMathematical model of zinc absorption: effects of dietary calcium, protein and iron on zinc absorption.
A previously described mathematical model of Zn absorption as a function of total daily dietary Zn and phytate was fitted to data from studies in which dietary Ca, Fe and protein were also measured. An analysis of regression residuals indicated statistically significant positive relationships between the residuals and Ca, Fe and protein, suggesting that the presence of any of these dietary comp...
متن کاملEffects of fructooligosaccharides on the absorption of iron, calcium and magnesium in iron-deficient anemic rats.
We investigated the effects of fructooligosaccharides (FO)-feeding on the absorption of iron (Fe), calcium (Ca) and magnesium (Mg) and on the biochemical parameters in Fe-deficient anemic rats. Fe-deficient anemic rats were made by feeding an Fe-deficient diet for 3 weeks. Then these Fe-deficient rats were fed an experimental diet that contained one of two levels of Fe (15 or 30 mg/kg diet), in...
