本文报告给２天日龄雏鸡每日１．５ｋＨｚ１２０ｄＢＳＰＬ高强纯音暴露８小时，共刺激６天；随后分０．１、２和３周处死动物，其耳蜗基底乳头（Ｂｐ）行扫描电镜（ＳＥＭ）和光镜（ＬＭ）观察，结果发现１．５ｋＨｚ强纯音仅造成鸡Ｂｐ基部至中部内侧较窄范围毛细胞损害，毛细胞消失率占３０％左右；当恢复１周后，受损处毛细胞迅速再生，至恢复２周后Ｂｐ基本正常。证明高强度纯音损害鸡内耳后受损区毛细胞有再生能力，再生毛细胞发育成熟而使Ｂｐ恢复正常形态。
In this paper, 2-day-old chicks were exposed to high-intensity pure-tone 1.5kHz120dBSPL for 8 hours daily for 6 days, and then sacrificed for 0.1, 2 and 3 weeks respectively. Their basal papilla (Bp) scanning electron microscopy (SEM) And light microscope (LM) observation, found that 1.5kHz strong pure tone only caused chicken Bp base to the medial narrow hair cell damage, hair loss accounted for about 30%; when recovered after 1 week, damaged hair cells rapidly Regeneration, to restore the basic Bp 2 weeks after normal. Proved high-intensity pure tone damaged chicken inner ear damaged hair cells regenerative capacity, regenerative hair cells mature Bp to restore normal form.
