Brief Summary

Attacks in Meniere's disease, characterized by vertigo and hearing loss, are well known to occur repeatedly under stressed environment. Hitherto, its pathology was revealed to be inner ear hydrops through human temporal bone studies in 1938. For the pathogenesis of inner ear hydrops resulting in Meniere's attacks, plasma vasopressin elevation due to stress and V2 receptor overexpression in the inner ear could be essential as a basis of this disease. In the present study, we'd like to find the effective and feasible way to reduce plasma vasopressin level in patients with Meniere's disease.
