Comparison of the effects of N-acetyl-cysteine and ginseng in prevention of noise induced hearing loss in male textile workers.

摘要: Previous studies revealed the role of antioxidant agents in prevention noise induced hearing loss (NIHL). The aim this study was to compare protective effect N-acetyl-cysteine (NAC) and ginseng on protection NIHL textile workers exposed continuous daily working. In study, 48 participants were randomly allocated three groups; Group I received NAC 1200 mg/day, II 200 III (control group) no supplement. Pure tone audiometry high frequency performed preshift before after 14 days (on day 15). Linear regression analysis results showed reduced noise-induced temporary threshold shift (TTS) for groups at 4, 6 16 kHz (P < 0.001) both ears. Furthermore, effects more prominent than ginseng. Our show that can reduce TTS occupational noise. Further are needed prove antioxidants benefits conservation programs.
