Abstract

Conclusion: Hydrogen gas effectively protected against the morphological and functional vestibular hair cell damage by reactive oxygen species (ROS).

Objective: ROS are generally produced by oxidative stress. In the inner ear, ROS levels increase as a result of noise trauma and ototoxic drugs and induce damage. It is thus important to control ROS levels in the inner ear. The protective effects of hydrogen gas in cochlear hair cells have been reported previously.

Methods: This study examined the effects of hydrogen gas on mouse vestibular hair cell damage by ROS using antimycin A.

Results: In the group *exposed to hydrogen gas, vestibular hair cells were morphologically well preserved and their mechano-electrical transduction activities were relatively well maintained when compared with controls. Hydroxyphenyl fluorescein (HPF) fluorescence in vestibular tissue was also reduced by hydrogen gas.

氢可以保护前庭毛细胞免受自由基的侵害。
结论:氢气对活性氧(reactive oxygen species, ROS)对前庭毛细胞形态和功能的损伤具有保护作用。目的:ROS一般由氧化应激产生。在内耳中,由于噪声创伤和耳毒性药物,ROS水平升高并引起损伤。因此控制内耳的活性氧水平是很重要的。氢气对耳蜗毛细胞的保护作用已有报道。方法:利用抗霉素a检测氢气对小鼠前庭毛细胞ROS损伤的影响。结果:与对照组相比,氢气暴露组*前庭毛细胞形态保存完好,其机电转导活性相对维持。前庭组织中羟基苯基荧光素(HPF)的荧光也被氢气降低。
