Title

EFFECT OF N-ACETYLCYSTEINE IN PROTECTING FROM SIMULTANEOUS NOISE AND CARBON MONOXIDE INDUCED HAIR CELL LOSS

Pages

  107-115

Abstract

 Background and Aim: N-ACETYLCYSTEINE, a glutathione precursor and reactive oxygen species scavenger, is reported to be effective in reducing NOISE-INDUCED HEARING LOSS. Many workers in industry are exposed simultaneously to noise and chemical pollutants such as CARBON MONOXIDE. We investigated effectiveness of N-ACETYLCYSTEINE in protecting the cochlea from simultaneous noise and CARBON MONOXIDE damages.Methods: Twelve rabbits were exposed simeltaneously to 100 dB sound pressure level of broad band noise and CARBON MONOXIDE 8 hours a day for 5 days.One hour before exposure, experimental group received 325 mg/kg of N-ACETYLCYSTEINE while normal saline was administered for the control group.The protective effect of N-ACETYLCYSTEINE was evaluated 3 weeks after exposure by histological assessment of the HAIR CELLs.Results: Simultaneous exposure to noise and CARBON MONOXIDE resulted in a considerable damage to the outer HAIR CELLs; however, the inner HAIR CELLs and the pillar cells remained intact. Use of Nacetylcysteine in the experimental group significantly reduced the extent of outer HAIR CELL loss.Conclusion: N-ACETYLCYSTEINE attenuates simultaneous noise and CARBON MONOXIDE induced HAIR CELL damage in rabbits.
