Understanding iron absorption and metabolism, aided by studies of hemochromatosis
1Central Kentucky Blood Center, Lexington 40504, USA.
Abstract:
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 are alcohol consumption, vitamin preparations with vitamin C, and iron consumed by individuals without anemia. Endogenous generation of excess iron by hemolysis, owing to abnormal hemoglobin or many transfusions, are not controlled by the intestinal barrier.

Methods for Studying Drug Absorption: In situ
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
