Physiology 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...
متن کاملBilirubin metabolism: Applied physiology
ont matter & 2005 2005.10.002 thor. Tel.: +1 718 . howdhur@aecom. Summary Bilirubin is the breakdown product of the haem moiety of haemoglobin and other haemoproteins. Because of internal hydrogen bonding, bilirubin is water-insoluble and requires enzyme-mediated glucuronidation in the liver for biliary excretion. In normal circumstances, plasma bilirubin is mostly unconjugated and is tightly b...
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 کاملTHE RELATIONSHIP BETWEEN ALUMINIUM TOXICITY AND IRON METABOLISM IN RATS
The relationship between aluminium toxicity and iron metabolism was studied. Male rats were exposed to aluminium by daily intraperitoneal injection of 40pmolelkg body weight. After 45 days, aluminium intoxified rats had a significant loweredserum ferritin (55%), iron (42%), TIBC (25%) and hemoglobin(31%). At thesame time the serum ceruloplasmin level was elevated by 60%. This result shows t...
