为了解噪声和卡那霉素对耳蜗功能的复合影响,作者用250只豚鼠,体重300—400克,耳廓反射均为阳性,在乌拉坦麻醉下观察处理前后耳蜗微音效应和动作电位的变化。对照组10只动物,其余动物分成4大组,每大组又分成6小组,每小组10只动物。各试验组动物在总声级为92—93分贝的噪声下刺激,并按1、2、3、4、5、6及12星期的刺激时间分别测试耳蜗功能。实验步骤如下:第一大组仅接受噪声刺激;第二大组在噪声刺激前注射卡那霉素1星期;第
To understand the combined effects of noise and kanamycin on cochlear function, we used 250 guinea pigs weighing 300-400 grams and having positive auricle reflexes. We observed the cochlear microneedis and action potential before and after anesthesia with urethane Variety. The control group of 10 animals, the remaining animals divided into 4 groups, each group is divided into 6 groups, each group of 10 animals. The animals in each test group were stimulated at a noise level of 92-93 dB and the cochlear function was tested at 1, 2, 3, 4, 5, 6 and 12 weeks of stimulation. The experimental steps are as follows: the first group received only noise stimulation; the second group injected kanamycin before noise stimulation for 1 week;
