Effects of Bushen Pill on Apoptosis Genes of Spiral Ganglion Cells Guinea Pigs with OtotoxityWANG Feng, ZHAO WulanZhejiang Chinese Medical University, Hangzhou 310053, China Abstract:ObjectiveTo explore the protective effects of Jingui Shenqi Pill on apoptosis genes of spiral ganglion cells in guinea pigs with ototoxity by gentamycin; MethodsThe ototoxity model was induced by abdominal injection of 100 mg/ gentamycin,while the treatment group took Jinguishenqi pill after injection of gentamycin, executed after the experiment, and the cochleas were gathered for detection.

作者：王枫，赵乌兰作者单位：浙江中医药大学，浙江杭州 310053 目的探讨金匮肾气丸对庆大霉素造成药物性耳聋豚鼠耳蜗螺旋神经节细胞凋亡调控基因表达的影响。方法豚鼠腹腔注射庆大霉素100 mg/制作耳聋动物模型，治疗组在注射庆大霉素后灌服金匮肾气丸水煎剂，实验结束后豚鼠断头处死，取耳蜗标本。

Methods Ten mature Wistar rats were divided into normal control group (5 rats) and adenovirus (E1, E3-Deleted and carried math1 and enhanced green fluorescent protein report gene, Ad-Math1-EGFP) scala vestibuli transfer group (5 rats). Right ears of the Ad-Math1-EGFP transfering group rats were deliveried 5μl Ad-Math1-EGFP (physical tite 2.1×10^11v.p./ml) into cochleas through the way of drilling scala vestibuli of cochlear basal turn. As a control, the normal group received nothing to inner ear. In order to estimate functional condition of vestibule and cochlea, the click-evoked potentials on the surface of the cervical dura mater, auditory brain stem response and swimming time were recorded in all rats at 7 days after treatment, and then histologic and morphologic observation were carried out after animals were sacrificed. Results All animals' morphologic observation showed that inner ear hair cells were normal after transfer.

将10只成年Wistar大鼠分为正常对照组和缺失E1、E3基因片段且构建有Math1基因和绿色荧光蛋白报告基因的复制缺陷型腺病毒(adenovirus-Math1-enhanced green fluorescence protein， Ad-Math1-EGFP)前庭阶导入组，每组5只，实验组大鼠在右耳通过耳蜗底回前庭阶打孔的方法导入物理滴度为2.1×10^11v.p/ml的上述腺病毒5μl，对照组大鼠不做任何处理。7天后对动物进行颈髓硬膜外短声诱发电位(click-evoked potentials on the surface of the cervical dura mater， CDM-CEP)、听性脑干反应阈值检测和游泳试验，评价前庭和耳蜗功能，然后将动物处死进行组织形态学观察。
