Chronic cochlear de-efferentation and susceptibility to permanent acoustic injury

Hearing Research, 1995
The question of whether olivocochlear (OC) efferent feedback can decrease permanent damage from acoustic overexposure was investigated by comparing the chronic threshold shifts and cochlear histopathology in guinea pigs either surgically de-efferented or sham-operated and then exposed (awake and unrestrained) to a 109- or 112-dB narrow-band noise ...

Ozone Prevents Cochlear Damage From Ischemia–Reperfusion Injury in Guinea Pigs

Artificial Organs, 2017
AbstractThe cochlea is an end organ, which is metabolically dependent on a nutrient and oxygen supply to maintain its normal physiological function. Cochlear ischemia and reperfusion (IR) injury is considered one of the most important causes of human idiopathic sudden sensorineural hearing loss. The aim of the present study was to study the efficacy of

The Healing Of The External Cochlear Wall In The Guinea Pig After Mechanical Injury

Acta Oto-Laryngologica, 1973
The bony and vascular repair process of the cochlea was studied after mechanical lesions on the external cochlear wall in the guinea pig. Bony healing of the bulla and the cochlear wall occurred surprisingly rapidly. Intracochlear hemorrhage appeared to be controlled by reflex closure of the supplying vessels.

Cochlear nerve injuries caused by cerebellopontine angle manipulations

Journal of Neurosurgery, 1987
✓ Changes in the response from the cochlear nerve in dogs resulting from cerebellopontine angle (CPA) manipulations were correlated with histological changes in the nerve. The aim of this study was to determine the mechanisms underlying hearing deficits incurred as a result of manipulations in the CPA.

Ionic changes in cochlear endolymph of the guinea pig induced by acoustic injury

Hearing Research, 1988
The effects of acoustic overstimulation on the endocochlear potential (EP) and on concentrations of ions (K+, Na+, Cl-, H+, HCO3-, and Ca2+) in endolymph were investigated using ion-selective microelectrodes. A slight but significant elevation of the EP and alkalinization of the endolymph were induced by acoustic overstimulation, whereas there was ...

Ferroptosis contributes to lead-induced cochlear spiral ganglion neurons injury

Toxicology
The underlying mechanisms of lead exposure-induced cochlear spiral ganglion neurons (SGNs) injury are not yet clear. This study explored whether ferroptosis is involved in lead-induced SGNs injury and investigated the mechanism of lead-induced iron overload in SGNs. A primary culture cell model of lead acetate-induced SGNs damage was established.
