【摘要】：目的:探讨口服甲硫氨酸片对噪声性听力损伤的预防作用。方法:选择某部健康男性军人203人作为受试者,随机分为实验组(113例)和对照组(90例),噪声暴露前两组分别给予口服甲硫氨酸片和安慰剂1 500mg/d×3d。两组受试者噪声暴露前、后均行纯音测听和ABR检查,对检查结果进行统计学分析。结果:噪声暴露前纯音听阈、ABR波Ⅰ~Ⅴ间期在两组之间无显著差异(P0.05),但两组之间在噪声暴露后1d、7d均存在显著差异(分别P0.01和P0.05);与各自噪声暴露前比较,纯音听阈、ABR波Ⅰ~Ⅴ间期,噪声暴露后1d实验组、对照组均存在显著差异(分别P0.05和P0.01);噪声暴露后7d实验组无显著性差异(P0.05),对照组差异有统计学意义(P0.05)。结论:噪声暴露前口服甲硫氨酸片可减轻噪声性听力损伤,但最佳使用时机还需进一步研究。

Before and after noise exposure, pure tone audiometry and ABR were performed in both groups. Results: before noise exposure, there was no significant difference in pure tone hearing threshold and ABR wave 鈪，
