Vasopressin and V2 Receptor in Meniere's Disease
Klíčová slova
Abstraktní
Popis
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).

| Experimental: 1. Meniere's disease Patients were eligible for enrollment if they had received a clinical diagnosis of Meniere's disease according to the 1995 AAO-HNS criteria (Committee, 1995). These criteria can be briefly described as follows: 1) Repeated attacks of vertigo: A definitive spell is spontaneous vertigo lasting at least 20 minutes. A mixed type of spontaneous nystagmus is observed during attacks. 2) Fluctuating cochlear symptoms: The hearing test usually reveals a marked fluctuation of the threshold in the low and middle tone range. | Genetic: 1. Meniere's disease plasma vasopressin, V2 receptor, cyclic AMP |
| No Intervention: 2. Acoustic neurinoma Diagnosed by CT and/or MRI |
