耳蜗中色素的存在早在Corti时就作过描述。这些黑素主要在蜗轴的骨壁、骨螺旋板、前庭膜和血管纹中。有些证据表明黑素具有维持耳蜗正常功能的作用,耳蜗性聋可与某些类型的色素异常同时并存。形成血管纹中间细胞层的色素细胞是具有一定功能的,它们与血管纹毛细血管的密切联系可能与血管运动控制机制有关。耳蜗血管系,特别是血管纹血管暴露于强噪声后的破坏表明,血管纹血管的色素细胞似乎是最易受过度声刺激的细胞。内耳色素含量与噪声诱发听力损失敏感性有关,同样强度的噪声刺激有色豚鼠和白化豚鼠,6天后有色豚鼠听力完全恢复,而白化豚鼠听力无明显改善。在人类受试者中发现TTS易感性同内耳色素呈反比关系,并证实色素与噪声诱发PTS之间可能有关。本文作者为证实以上见解,对20只有色野生
The presence of pigment in the cochlea was described earlier in Corti. These melanins are mainly found in the wall of the worm shaft, the bone spiral plate, the vestibular membrane and the vascular pattern. There is some evidence that melatonin plays a role in maintaining proper cochlear function. Cochlear deafness may co-exist with some types of pigmentation abnormalities. Pigmented cells that form the middle layer of the stria vascularis are functional and their close association with the capillary vessels of the vasculature may be related to the vascular motor control mechanisms. The breakdown of the cochlear vasculature, particularly the vascular veins after exposure to strong noise suggests that pigmented cells of vascular veins seem to be the most vulnerable cells to hyperexcitation. The content of pigment in the inner ear was related to the sensitivity of the noise-induced hearing loss. The noise of the same intensity stimulated colored guinea pigs and albino guinea pigs. After 6 days, the color guinea pigs recovered completely, while the albino guinea pigs had no significant improvement in their hearing. TTS susceptibility was found to be inversely proportional to the pigment in the human ear in human subjects and to confirm the possible correlation between pigment and noise-induced PTS. In order to confirm the above opinion, the authors of this article only colored the wild
