Abstract:
:31P-NMR spectroscopy of rat liver perchloric acid extracts was utilized to assess the hepatic energy state in an experimental model of chronic dietary iron overload. Oral administration of iron for a period of 65 days that induces a steady ten-fold increase in hepatic iron concentration causes a significant decrease in the hepatic ATP level not associated with appreciable modifications of ADP and Pi levels. The phosphorylation ratio appears on the average decreased. The values of the energy state parameters revert to the normal if the concentration of iron in the liver is reversed below the critical level upon withdrawal of iron treatment after 45 days for a period of 20 days. The implication of these energy modifications for the pathogenesis of cell damage in the siderosis is discussed.
