Inner ear changes in the ferret model for Reye's syndrome.

Abstract:

:The acute effects of influenza B, aspirin, and hyperammonemia on the inner ear were examined using the ferret model for Reye's syndrome. Histopathologic examination revealed varying degrees of vacuolization in both the sensory and nonsensory endolymphatic tissues of the cochlear and vestibular membranous labyrinth. The secretory epithelial cells of the stria vascularis and the vestibular dark cells appeared to be more severely affected, as demonstrated by the presence of an extensive number of intracytoplasmic vacuoles. The cells of the perilymphatic tissues appeared to be unaltered. Although all neuroepithelial regions of the inner ear appeared to be altered, an unexpected observation was that only the inner hair cells of the organ of Corti were pathologically affected. These results suggest that metabolic and virus-induced derangements may alter inner ear microhomeostasis in patients with Reye's syndrome and may potentially result in loss of hearing in such patients.
