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 کاملMicroscopic guide to the middle ear anatomy in guinea pigs.
OBJECTIVES To reveal microscopic surgical anatomy of the middle ear in guinea pigs (GPs). MATERIALS AND METHODS Twenty ears of GPs were dissected under dissection microscopy via inferior approach. By using digital equipment, the most suitable photograph was taken for each step. Differences and similarities between the ears of GPs and those of human beings are discussed to show the advantages ...
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 کاملLight and scanning electron microscopic study of the lingual structure in the budgerigar (Melopsittacus undulatus)
BACKGROUND: The tongue, which plays a very important role in food intake by vertebrates, exhibits significant morphological variations that appear to represent adaptation to the current environmental conditions of each respective habitat. OBJECTIVES: The aim of the present investigation was to investigate lingual structure in adult budgerigar. METHODS: Tongues of 12 adult budgerigars were used ...
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...
