耳蜗毛细胞的丧失为耳聋最常见的原因。本文介绍鸟纲耳蜗经耳毒性药物及噪音损伤后,毛细胞可再生,再生后接近正常形态,功能亦恢复。预料今后有可能使人的毛细胞再生或进行毛细胞移植。当今噪声损伤耳蜗毛细胞致聋最为常见。近代对鸟纲听觉系统研究显示,噪声及耳毒性药物使毛细胞受损,而毛细胞可再生,使耳蜗的解剖形态及功能的恢复接近正常水平。 The loss of cochlear hair cells is the most common cause of deafness. This article describes the bird’s eye cochlear ototoxic drugs and noise damage, hair cells can be regenerated, close to normal morphology, function also recovered. In the future, it is expected that human hair cells may be regenerated or subjected to hair cell transplantation. Today’s noise-damaged cochlear hair cells are the most common deafness. Modern research on the bird’s hearing system shows that noise and ototoxic drugs damage the hair cells, while the hair cells are regenerated, so that the cochlear anatomy and function recovery close to normal levels.
