Abstract:OBJECTIVES: This study aimed to explore the molecular mechanism of the protective effects of hydrogen-saturated saline on Nihl。
方法: 豚鼠分为三组:氢饱和盐水;正常盐水;和控制。对于盐水的给药,豚鼠每天在噪声暴露前3 d和1小时进行每天的腹部注射。 ABR是TESTED检查人工耳蜗生理变化。 The changes of 8-hydroxy-desoxyguanosine (8-HOdG), interleukin-1 (IL-1), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-α(TNF-α), intercellular cell adhesion molecule-1 (ICAM-1) and high mobility group box-1 protein (HMGB1) in the cochlea还对此进行了检查。
结果: 结果表明,使用氢盐水盐水的预处理可能会显着减轻噪声诱导的听力损失。与正常盐水组相比,氢盐水组的8-HODG浓度也显着降低。噪声暴露后,与正常盐水组相比,在氢饱和盐水组中豚鼠的耳蜗中IL-1,IL-6,TNF-α和ICAM-1的浓度大大降低了。氢盐水组中HMGB-1和IL-10的浓度显着高于NO中的HMGB-1和IL-10rmal saline group immediately and at 7 d after noise exposure.
CONCLUSIONS: This study revealed for the first time the protective effects of hydrogen-saturated saline on noise-induced hearing loss (NIHL) are related to both the anti-oxidative activity and anti-inflammatory activity.
