Acrylonitrile Potentiates Noise-Induced Hearing Loss in Rat

Acrylonitrile produces transient cochlear function loss and potentiates permanent noise-induced hearing loss.

There is growing evidence that agents that produce oxidative stress in the cochlea have significant ototoxic potential by themselves and can potentiate noise-induced hearing loss as well. Acrylonitrile (ACN) metabolism entails conjugation with glutathione, resulting in rapid and pronounced depletion of this important antioxidant in many organs including brain, liver, and kidney. ACN metabolism ...

THE EFFECT OF NOISE-INDUCED HEARING LOSS ON DENTISTS

This paper presents noise problems associated with the use of air-turbine drills in dental practice. Two hundred and fifty dentists (male and female) were randomly selected from the faculty of dentistry as well as the dentists who worked private in Tehran. The results indicated that the mean value of sound pressure level produced by the high-speed drills was 69.1 db. Most of the energy from...

noise-induced hearing loss: prevention is possible

conclusions despite rising figures of reported occupational hearing loss, working nbii statistics show that the nihl problem in the danish work environment has, in fact, decreased. in our study, we found that roughly one third (around 100 cases) of the 272 screened persons presumably had nihl, taking into account 88 probable cases (column b) and 44 questionable ones (column c + 16 ski slopes). ...

Occupational noise induced hearing loss in coal miners and coal washing factory workers in Kerman province

Introduction: The occupational noise induced hearing loss is one of the wide spread problems and a long term complication of working in noisy environments. At the present, large groups of workers who are working in noisy environments are exposed to hearing loss. So, this study is aimed to determine the prevalence of hearing loss (more than, 25 dB) of the workers in coal mines and leaching fac...
