title: A copper-sulfur complex in the liver of a patient with Wilson's disease.
abstract: An asymptomatic 16-year-old boy was found to have Wilson's disease without Kayser-Fleischer rings. Liver biopsy showed chronic active hepatitis with 1025 micrograms copper/g dry weight. After 19 months of d-penicillamine therapy, the liver histology became almost normal and the copper content decreased to 238 micrograms/g dry weight. The liver specimens obtained before and after treatment were studied by X-ray probe microanalysis. After treatment, both copper and sulfur decreased in hepatocellular lysosomes. The estimated molar ratio of the decreased copper to the decreased sulfur was 32/100. These figures suggest that lysosomal copper exists in the form of metallothionein.
