The Preyer's reflex ( PR) threshold shift and brainstem auditory evoked potential ( BAEP) were taken as indexes. 以耳廓反射(PR)及脑干听觉诱发电位(BAEP)监测作为指标,观察子代豚鼠是否发生耳聋。
Methods Forty healthy guinea pigs with normal Preyer's reflex were used. The animals were randomly divided into four groups: normal group, conditioning noise group, high-level noise group and conditioning noise followed by high-level noise group. 方法取健康成年豚鼠40只,随机分为正常对照组、噪声习服组、噪声损伤暴露组和噪声习服后损伤暴露组。
The obervation indexes were: Animals general conditions, preyer's reflex threshold ( PR), auditory brain stem response ( ABR) and calculation of the number of cochlear hair cells. 观察指标为动物的一般状态、耳廓反射(PR)、ABR及耳蜗毛细胞计数。
The experiments have been performed using Preyer's reflex, cochlear potential, and surface preparation of the cochlear as indexes of the auditory function. 本研究以耳廓反射、耳蜗生物电和耳蜗铺片为指标,观察东莨菪碱对豚鼠庆大霉素中毒性耳聋的预防作用。
Aim and Methods: Preventive effect of electroacupuncture on ototoxicity induced by gentamycin ( GE) was observed with Preyer's reflex ( PR), brainstem auditory evoked potential ( BAEP) and histochemistry method in guinea pigs and its mechanism was explored. 目的和方法:本实验用耳廓反射(PR)、脑干听觉诱发电位(BAEP)、组织化学方法,观察电针疗法对豚鼠庆大霉素(GE)耳毒性的防治作用,并探讨其机制。
