Research Abstract

About 30% of the 120 million people worldwide who suffer from congenital (early-onset) hearing loss are syndromic, and the remaining 70% are non-syndromic. At present, however, no effective therapies for deafness have been established except for cochlear implantation. This study demonstrated that oral administration of small molecule to C57BL/6 mice for one month significantly showed preventive effects on age-related/noise-induced deafness. This study is further trying to elucidate a mechanism for preventive effects on hearing losses.
