给实验组鸡按50mg／（kg·d）剂量肌注庆大霉素共10d后，间隔1、3、6、9和12d对实验组和对照组鸡耳蜗电位（Ap）及听觉脑干诱发电位（ABR）进行测定，随后处死动物，用透射电镜（TEM）和扫描电镜观察鸡基底乳头（BP）毛细胞再生的超微结构和过程，结果可见毛细胞再生来源于Bp表层扁平状或立方形上皮细胞，在早期再生毛细胞胞质密度高，含有大量的线粒体，随后静纤毛长出，细胞核出现，表皮极发育成熟时静纤毛束形成，其毛细胞底部的神经末梢已长出，此时伴有Ap和ABR阈值的恢复。说明再生毛细胞形态成熟时已具有听觉功能的恢复，再生毛细胞在受损耳蜗听功能的恢复过程中起主要作用。
To the experimental group, the cochlear potential (Ap) and auditory brainstem response of the experimental group and the control group were induced by intramuscular injection of gentamicin at a dose of 50 mg / (kg · d) for 10 days at 1,3,6,9 and 12 d intervals (ABR), and then sacrificed. The ultrastructure and process of hair cell regeneration in chicken basilar papilla (BP) were observed by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The results showed that hair cell regeneration originated from flat or cubic Bp surface Shaped epithelial cells, high density of cytoplasm in early regenerative hair cells, containing a large number of mitochondria, followed by the formation of static cilia, nuclei appear, very mature when the epidermal very mature cilia bundles of hair, the bottom of the hair cells nerve endings have grown, this With recovery of Ap and ABR thresholds. It shows that the regenerative hair cells have the recovery of auditory function when their morphology is mature, and the regenerative hair cells plays a major role in the recovery of hearing loss of damaged cochlea.
