摘要: 应用正弦摆动、旋转与冷热刺激方法诱发豚鼠眼震,眼震电图记录得正弦摆动眼震,左右向对称,振幅2.8±0.4μV,频率3.2±0.3次/s;旋转试验记录了加、减速期与骤停时的眼震振幅与频率;分别用0、10、20、30、45℃的水作冷热刺激,获得相应眼震数据。前二者反映双侧半规管功能,但以一侧为主。冷热试验中发现豚鼠对冷水(尤以冰水)敏感。本文结果为开展豚鼠前庭功能与结构的实验研究工作提供参考数据。

Abstract: The nystagmus of guinea pig were induced by using sinusodial pendular,rotatory and caloric stimulus test in this experiment. By electronystagmography,the sinusodial pendular nystagmus were recorded with it’s symmetrical distribution in left - right directions, the amplitude 2.8±0.4μV and the frequency 3.2±0.3/s ;In rotatory test, the nystagmus of accelerated,descended and sudden stoping stage were also recorded;In caloric test,0、10、20、30 and 45℃ water were used to stimulate the guinea pigs respectively,and the correlative nystagmus data were obtained. The both former reflect the function of bilateral semi -canal,but unilateral mainly. The results suggested that guinea pig was most sensitive to cold water,especially to ice water. This experiment provided reliable basis for experimental research on the vestibular function and structure in guinea pigs.
