The relationship between iron absorption and hepatic iron was studied in 21 patients with hemochromatosis. Iron absorption was studied using 59Fe and total body counting and hepatic iron was measured by atomic absorption spectrophotometry. Iron absorption was inversely related to hepatic iron concentration (r = -0.51, p = 0.009) in this patient population. This observation suggests that iron absorption is regulated by body iron stores even in hemochromatosis, and does not support the hypothesis that the primary metabolic defect in hemochromatosis is a deregulation of iron absorption in relation to iron stores.

D007504	Iron Radioisotopes	Unstable isotopes of iron that decay or disintegrate emitting radiation. Fe atoms with atomic weights 52, 53, 55, and 59-61 are radioactive iron isotopes.	Radioisotopes, Iron
D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D006432	Hemochromatosis	A disorder of iron metabolism characterized by a triad of HEMOSIDEROSIS; LIVER CIRRHOSIS; and DIABETES MELLITUS. It is caused by massive iron deposits in parenchymal cells that may develop after a prolonged increase of iron absorption.
