Copper (Cu) accumulating bound to metallothionein (MT) in the liver of LEC (Long-Evans with cinnamon-like coat color) rats due to a hereditary metabolic disorder is assumed to lead to acute hepatitis with severe jaundice. The metal was shown to be present in the liver in a form not bound to MT at the beginning of hepatitis after first delivery and lactation. Following this change in the distribution of Cu from MT-bound to non-MT bound form in the liver, changes in the concentrations and distributions of Cu, zinc (Zn) and iron in the plasma and kidneys of LEC rats were also observed. Cu plasma distribution on a gel filtration column by HPLC-ICP revealed that the holo-form of ceruloplasmin (Cp) was present before hepatitis and increased with its development, indicating the availability of Cu for Cp by hepatitis. Cu-binding proteins migrating at the same retention times as those of hepatic Cu-MT and Cu,Zn-superoxide dismutase (SOD) were detected in plasma during hepatitis. Albumin was largely present in the form of nonmercaptoalbumin, reflecting that the bloodstream was under oxidative stress. A sudden increase in the concentration of Cu in the kidneys occurred with hepatitis, and the metal came to be distributed more to high molecular weight proteins with its development.
