Morphological studies on middle ear barotrauma in guinea pigs.
Experimental middle ear barotrauma was studied morphologically. White guinea pigs were placed in an experimental hyperbaric chamber, and middle ear barotrauma was created by increasing the pressure in the hyperbaric chamber from 1 atmosphere absolute (ATA) to 2 ATA using pure oxygen, maintaining the pressure at 2 ATA for 10 minutes, then again reducing the pressure to 1 ATA. Selected experiment...
متن کاملMagnetic resonance imaging in a guinea pig model of inner ear decompression sickness and barotrauma.
OBJECTIVES/HYPOTHESIS Scuba diving may cause severe hearing loss and vertigo due to inner ear barotrauma and decompression sickness. These may be difficult to differentiate clinically. Decompression sickness requires costly and potentially dangerous hyperbaric therapy, whereas such treatment may worsen barotrauma. The objective of this study was to assess the potential utility of magnetic reson...
متن کاملProtective effect of neurotrophic agent T-817MA against inner ear barotrauma in the guinea pig.
T-817MA (1-{3-[2-(1-benzothiophen-5-yl)ethoxy]propyl}azetidin-3-ol maleate), a neurotrophic compound newly synthesized for the treatment of Alzheimer's disease, has been found to reduce oxidative stress and exert neuroprotective effects. By assessing the auditory functioning and observing the cochlear sensory epithelia, we investigated whether T-817MA protects the cochlea from inner ear barotra...
متن کاملInner ear barotrauma: a retrospective clinical series of 50 cases
(Edmonds C. Inner ear barotrauma: a retrospective clinical series of 50 cases. SPUMS J. 2004; 34: 11-4.) A retrospective series of 50 cases of inner ear barotrauma is reviewed, as regards the diving and otological history, the clinical manifestations, basic audiometric investigations and treatments. This disorder may be predicted to some degree by a previous history of otological barotraumas, o...
متن کاملAuditory function and inner ear pathology in guinea pigs with peripheral nerve demyelination
The audiological or physiological data showed that auditory neuropathy was due to the demylination disease in peripheral nerve, especially in auditory nerve. The aim of this study was to explore the changes of auditory function and auditory nerve pathology through establishing a guinea pig model with demyelinated peripheral nerve. The guinea pig model was established by immunizing guinea pigs w...
