Abstract:
:To understand better the intracellular iron distribution and metabolic consequences of chronic hepatic iron overload, rats were given large doses of iron dextran or ferric citrate intraperitoneally. They accumulated large quantities of iron within Kupffer cells and hepatocytes. The relative subcellular iron distributions were similar in controls and iron-loaded rats, despite a ten- to 20-fold difference in hepatic iron concentration. Electron microscopy of whole liver and subcellular particulate fractions suggested that iron was present in highest concentration in lysosomes, which were rendered more labile by its presence. Nevertheless, quantitative iron determinations on all subcellular fractions, obtained by two preparative methods, showed that most of the iron was present in the "soluble" fraction. The amount of iron in the "microsomal" fraction varied, depending on the techniques used for preparation of this fraction. Cytochrome P-450 and total heme concentrations were decreased 40% to 50% in microsomes isolated from iron-loaded livers.
