The concentration of copper in the liver of African children with marasmus.

I. The concentration of copper in the liver of six African children suffering from marasmus has been compared with the values found for six children from the same area suffering from other diseases. 2. No significant difference was found in the concentration of Cu in the livers of children with marasmus compared with the values for the controls when the results were expressed either on a dry whole tissue basis or on a dry fat-free basis. 3. A highly significant difference was found in the concentration of Cu in the livers of children with marasmus when these values were compared, on a dry fat-free basis, with those found in an earlier study for children with kwashiorkor. The concentration of Cu in the livers of children with marasmus was twice that in the children with kwashiorkor.
