Abstract

Reye's syndrome is an acute illness in children manifested by encephalopathy, fatty infiltration of liver, and thymic hypoplasia. The syndrome usually occurs in a susceptible individual with a viral illness who has ingested salicylate. We previously investigated the metal status of children with this syndrome; serum Se and Cu levels were noted to be decreased. Chronic aspirin treatment of rats also produced alterations of serum Se, and liver Se and Cu. We now report our observations for an experimental model of Reye's syndrome. Analysis by PIXE of various metals in Se- and Cu-deficient mice exposed to virus and salicylate are discussed.
