摘要:
目标: 的听力诱发的听力损失是一种可预防的听力损失形式,是一种严重的社会和经济影响。这项研究旨在研究贝雷贝林(一种有效的抗氧化剂和抗炎剂)针对噪声引起的听力损失的保护作用。
方法: 应用失真产物耳声发射后,将28个雌性Sprague-Dawley大鼠随机分为四组。第1组被指定为声学创伤组,该组中的大鼠以4 kHz 110 dB的声压水平的强度暴露于白噪声12小时。第2组是对照组。第3组被指定为berberine组,并连续五天通过胃内灌洗对这一组的大鼠施用100 mg/kg的小berberine。第4组被指定为声学创伤+berberine组。 distortion product otoacoustic emission was repeated on the 6th day of the study and cochlear tissues of rats were dissected for histopathological and immunohistochemical analyses after sacrificing rats.
RESULTS: The distortion product otoacoustic emission results showed a significant decrease in signal-noise ratio创伤组大鼠中较高频率的值o其他团体。声学创伤在人工耳蜗上引起严重的组织病理学障碍,以及严重的8-羟基-2-脱氧鸟苷的表达。 Rats in the acoustic trauma+berberine group showed mild histopathological changes with mild 8-hydroxy-2-deoxyguanosine expression and better signal-noise ratio values.
CONCLUSION: The histopathological and audiological findings of this experimental study showed that berberine provides protection in Noise-induced hearing loss并且可能有可能用于与声学创伤相关的听力损失。
