给猫注入庆大霉素,在用药前、用药过程中以及用药后,采用头皮电极记录出短潜伏期的前庭诱发反应(VsER)。庆大霉素是氨基糖甙类抗生素,对耳蜗的影响,经耳蜗微音电位和ABR做出评价。但没有类似可靠的方法评价前庭的功能。近年来通过动物试验,利用加速刺激的方法诱出短潜伏期的VsER,这是一种新的无害的检查方法,类似短声诱发的ABR,可靠的提供了前庭功能的电生理变化,并与庆大霉素治疗后的前庭器的组织病理改变做对照,同时采用ABR记录听觉功能,结合耳蜗组织学 Gentamicin was infused into cats. The short latency incubation period (VsER) was recorded by scalp electrodes before medication, during and after medication. Gentamicin is an aminoglycoside antibiotic that affects the cochlea and is evaluated by the cochlear microphones and ABR. However, there is no similar reliable method to evaluate vestibular function. In recent years, animal tests have been used to induce short latency VsER using accelerated stimulation, a new and innocuous method similar to the ABR induced by short beats, which reliably provides electrophysiological changes in vestibular function and correlates with Gentamicin treatment of the vestibular tissue histopathological changes as a control, while using ABR auditory function, combined with cochlear histology
