Brief Summary:
Summary: Some of sicknesses are well known to be provoked by inadequate adaptation to physical and/or psychogenic stress in their daily life. Meniere's disease is also a common inner ear disease accompanied with vertigo, hearing loss and tinnitus especially in civilized people under stressed life style. Its oto-pathology was firstly revealed in 1938 to be inner ear endolymphatic hydrops through the temporal bone study. To elucidate the neuroscientific relationship between "stress" and "inner ear", we examined plasma vasopressin (the anti-diuretic "stress" hormone) and its receptor, V2R in the endolymphatic sac (the "inner ear" endo-organ for endolymph absorption) in Meniere's patients.
Detailed Description:
Methods: Between 1998 and 2006, we enrolled and assigned 105 intractable Meniere's patients to examine plasma vasopressin during remission of vertigo attacks (controls: 30 patients with chronic otitis media). Using the real-time PCR method, we examined V2R mRNA expression in the endolymphatic sac in 12 patients (controls: 6 patients with acoustic neurinoma). By means of cell culture and cyclic AMP assay, we also examined cyclic AMP activity in the endolymphatic sac in 3 patients (controls: 3 patients with acoustic neurinoma).
