Iron absorption in gastric and duodenal pathology in patients with iron deficiency anaemias.Folia Haematol Int Mag Klin Morphol Blutforsch. 1976; 103(6):906-14.FH
Absorption of radioactive iron was studied in 87 patients with different types of iron deficiency anaemias and in 23 healthy subjects. The subjects were given 1...2muci of radiactive iron in the form of FeSO4 together with 5 mg of nonradioactive iron as a carrier and 100 to 150 g of white bread, radioactivity on the whole body being studied with a big liquid scintillation counter 4 pi (BLSC-2). In clinical observations and in single experiments on volunteers there was no conformity of the values of absorption with the levels of acid-formation. But in the same time the gastric juice from an anaemic horse almost doubled iron absorption in healthy individuals. Marked morphological changes in the gastric mucosa inhibited the absorption in the intestine and the degree of increase of absorption in patients with anaemia depended to some extent on the morphological conditions of the gastric mucosa. When healthy subjects and patients with iron deficiency anaemia were given bread "enriched" with iron before baking instead of common bread with "external" mark there was observed similar correlation between the values of absorption but the figures were somewhat lower.
