Iron-ethanol synergism and pathological liver transformation



Iron-ethanol synergism and pathological liver transformation



In Vivo 13(1): 13-20



The synergistic effects of iron overload and ethanol on the liver of mice were studied over a period of 46 weeks. The determination of several parameters (iron, calcium, magnesium, alpha-hydroxyproline, lipid peroxidation, hepatomegalic and splenomegalic indexes) showed that ferrous and ferric lactates provoke an increase of calcium in the liver, higher than that of ethanol in the control animals. The relationship between liver calcium homeostasis modification and the increase of collagen and lipid peroxidation is discussed. Histological examinations showed differences in the tissular characteristics especially when iron and ethanol were given together. These findings suggest the liver calcium homeostasis changes found as a synergistic effect in the early stages of chronic iron overload may be of importance as a trigger of events leading to the pathway of fibrosis-->cirrhosis-->hepatocarcinoma reported in pathologies such as nutritional siderosis and hemochromatosis.
