• 論文の詳細を見る

• T-817MA (1-{3-[2-(1-benzothiophen-5-yl)ethoxy]propyl}azetidin-3-ol maleate), a neurotrophic compound newly synthesized for the treatment of Alzheimer’s disease, has been found to reduce oxidative stress and exert neuroprotective effects. By assessing the auditory functioning and observing the cochlear sensory epithelia, we investigated whether T-817MA protects the cochlea from inner ear barotrauma in guinea pigs treated with rapidly intense pressure change. Sustained oral administration of T-817MA significantly reduced the extent of auditory threshold shifts and outer hair cell loss, indicating that T-817MA attenuates the intense pressure–induced cochlear damage that accompanies inner ear barotrauma via antioxidative activity.
