[Experimental studies on allergic endolymphatic hydrops].
Jiro Hozawa, Shigeki Kamata, Takashi Ishida and Noriko Kimura (Hirosaki University) The labyrinths of guinea pigs sensitized by horseradish peroxidase (HRP) were investigated by electronmicroscopy after challenging this antigen through the foram. stylomastoideum. Horizontal nystagmus toward the contralateral side was observed about fifteen minutes after challenging. The animals sacrified in thi...
متن کاملTinnitus & early endolymphatic hydrops.
Ménière's disease with all of its clinical manifestations can be divided into two categories – those symptoms that derive from the cochlea (the anterior labyrinth) and/or those that arise from the vestibular labyrinth or the posterior part of the inner ear. The symptoms that arise from the cochlea include hearing loss, which can be fluctuant and progressive and often is, or tinnitus which can b...
متن کاملEffects of endolymphatic sac decompression surgery on endolymphatic hydrops.
CONCLUSIONS The present findings suggest that complete control of vertigo after endolymphatic sac decompression surgery (ESDS) does not always depend on improved vestibular function or reduced endolymphatic hydrops. Vertigo control is, however, associated with hearing stability. OBJECTIVE Among surgical treatments for intractable Meniere's disease, ESDS is performed to preserve and improve in...
متن کاملEffects of cholera toxin on cochlear endolymph production: model for endolymphatic hydrops.
To evaluate a possible role for adenylate cyclase [ATP pyrophosphate-lyase (cyclizing), EC 4.6.1.1] and adenosine 3':5'-cyclic monophosphate in the secretion of endolymph, we studied the effect of an intra-scala media injection of purified cholera toxin (an adenylate cyclase stimulant) on cochlear endolymph volume, endolymphatic potential, and endolymphatic Na and K concentrations.
متن کاملDelayed endolymphatic hydrops as a clinical entity.
Delayed endolymphatic hydrops (DEH) is a clinical entity that can be differentiated from Ménière's disease and is typically observed in patients who have been suffering from longstanding unilateral profound inner-ear hearing loss. DEH probably is caused by delayed atrophy or fibrous obliteration of the endolymphatic resorptive system of the membranous labyrinth. The time that elapses between th...
