| Research Abstract |
We tried to treat presbycusis by giving a ER stress-blocker, TUDCA, to different two types of mice. Presbycusis in one type of mice is promoted by progressive loss of auditory hair cells, which was not able to be attenuated by administratin of TUDCA. On the other hand, presbysis in the other type of mice which is promoted partly by loss of spiral ganglion cells was statistically significantly prevented by long-term continueous administration of TUDCA. The results were suggestive of future possibility of attenuating presbycusis by reducing ER stress.
