Summarydetailed history by an investigator who was also familiar with the many preparations other than aspirin that contain salicylates.
A mode1 salic~late intoxication was in ferretsTherefore, salicylates seemed to be the best candidate for a copermit the evaluation of the interaction with viruses isolated from factor, although other agents may be involved on occasion, patients with Reye's syndrome. Salicylate intoxication producedAnimal models can provide an approach to diseases with a a mild elevation of the serum glutamic oxaloacetic transaminase multifactorial etiology because the etiologic factors can be manipand fatty changes in the liver, but these changes differed from ulated independently. Therefore, to test the hypothesis that acute those seen in eye's syndrome on light and electron m i c r o s c o~~. salicylate intoxication interacts with viral infection to produce RS, Salicylates were associated with decreased activity of hepatic a model of salicylate intoxication in ferrets was developed and phosphovlase and a slight depression of activity of ornithine utilized to evaluate the effect of virus pius salicylates. The ferret transcarbam~lase, a mitochondria1 urea cycle enzyme-Infection selected for these studies because it is the only animal that with influenza viruses produced mild fatty changes in the liver, but could be infected easily with influenza viruses isolated from did not significantly potentiate the effects of salicylate intoxication patients with RS, and it develops an illness similar to human on the over-all mortality, the degree of fatty changes, or the influenza (15).
