Understanding 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 کاملBasic understanding of posterior probability
Consider the following task [Task A] A prenatal test determines whether an unborn child has a chromosomal anomaly. A priori, namely, before undergoing the test, a pregnant woman has a 4% chance of having a child with the anomaly. If a woman has a child with the anomaly, there is a 75% chance that she has a positive test result. If she does not have a child with the anomaly, there is still a 12....
متن کاملIron metabolism; utilization of intravenous radioactive iron.
T HE HUMAN body shows great economy in its handling of iron. Only small amounts of iron arefound in the excreta, and these amounts cannot be appreciably increased through loading body iron stores by oral ingestion,’ by parenteral iron administration2 or by multiple blood transfusions.3 These observations imply that iron is rigidly conserved by the body and that no attention need be directed tow...
متن کاملPhysiology of iron metabolism.
A revolution occurred during the last decade in the comprehension of the physiology as well as in the physiopathology of iron metabolism. The purpose of this review is to summarize the recent knowledge that has accumulated, allowing a better comprehension of the mechanisms implicated in iron homeostasis. Iron metabolism is very fine tuned. The free molecule is very toxic; therefore, complex reg...
