目的探讨镁在噪声性听力损伤(NIHL)发展过程中的影响及决定作用。方法查阅近年有关NIHL的文献,就有关镁影响NIHL的研究进展进行总结,并加以概述。结果噪声暴露后产生应激反应,引起肾上腺素分泌,使细胞内镁转移到细胞外,并增加尿镁排泄,耗损体内储留镁,当体内镁含量不足、又不能 Objective To investigate the effect of magnesium on the development of noise-induced hearing impairment (NIHL) and to determine its role. Methods To review the literature on NIHL in recent years and summarize and outline the research progress on the effects of magnesium on NIHL. Results After exposure to noise, there was a stress response that led to the secretion of epinephrine, which led to the extracellular transfer of intracellular magnesium and increased excretion of magnesium and magnesium, depleting magnesium in the body. When the body magnesium content was insufficient,
