ABSTRACT
Methods are described for measurement of total tissue iron, ferritin iron, haem iron and ferritin protein in approx. 15 mg of tissue obtained by liver biopsy. The validity of these methods is examined by comparison with the values observed in larger samples of the same post-mortem derived liver tissue. Correlation coefficients vary between 0.80 and 0.99 (n = 11--16). It appears that in post-mortem liver tissue the haem iron concentration is higher than in biopsy specimens from patients. Analysis of liver biopsy specimens from patients with hepatitis showed a large variation in the mean iron content of the liver ferritin molecules. Also, the non-ferritin depot iron concentration and ferritin protein concentration is quite variable. It is suggested that in cases of advanced ferritin catabolism during hepatitis the mean percentage of iron in ferritin molecules often increases while at the same time the non-ferritin depot iron fraction decreases, probably because of iron release from the liver.
