摘　　要：运用自行设计制作的椎基底动脉部分脑缺血动物模型，研究椎基底动脉阻断前后ＣＢＦ和ＡＢＲ变化。３１只豚鼠在血管阻断后ＣＢＦ减少至４７．４１ＡＢＬ％（基线％），与此同时，ＡＢＲ随阻断时间延长，Ⅲ波的反应阈提高、潜伏期延长、波幅减低。显示ＣＢＦ和ＡＢＲ之间的平行关系，说明ＡＢＲ可灵敏地反映耳蜗功能。his report deals with the animal model of VBI that designed and manufactured by ourselves.The changes ofCBF and ABR before or after occlusion of vertebro-basilar artery were investigated by laser Doppler flowmetry andERA 2250.These results show parallel relationship between CBF and ABR,and illstrate that the ABR can reflectbrainstem and cochlea function sensitively.
