为探讨超声（Ultrasound，FU）对豚鼠耳蜗毛细胞的影响，分别以2．5MHz、8MHz非聚焦超声（NFU）照射豚鼠耳蜗3h、6h，于30min后行耳蜗毛细胞组织学及酶组织化学观察。发现照射6h组在基底膜第2周起始段0．87±0．20mm节段及基底周起始段0．80±0．20mm节段，耳蜗毛细胞琥珀酸脱氢酶（SDH）活性降低，乳酸脱氢酶（LDH）活性升高。提示：2．5MHz、8MHzNFU照射豚鼠耳蜗达一定剂量能引起不同部位耳蜗毛细胞有氧代谢改变。
To investigate the effects of ultrasound on cochlear hair cells in guinea pigs, the cochlear cells were exposed to 2.5MHz, 8MHz unfocused ultrasound (NFU) for 3h and 6h, respectively. Cochlear histology and enzymatic histochemistry were observed after 30min . It was found that in the 6h group, the activity of succinate dehydrogenase (SDH) in the hair cells of the cochlea was significantly higher in the segments of 0.87 ± 0.20mm at the beginning of the second week and 0.80 ± 0.20mm of the basal week Lower, lactate dehydrogenase (LDH) activity increased. Tip: 2.5MHz, 8MHzNFU irradiated guinea pigs up to a certain dose of cochlear can cause different parts of cochlear hair cells aerobic metabolism changes.
