Immunogenicity of fatty acid anilides in rabbits and the pathogenesis of the Spanish toxic oil syndrome

Summary Fatty acid anilides, the major xenobiotic found in the cooking oils responsible for the Spanish toxic oil syndrome, are immunogenic for rabbits as ascertained by a skin test reaction, the characterization of specific antibodies against anilides and the immunofluorescent detection of anilide dependent antigens in tissue slices from treated animals.Acknowledgments.
