objective: to explore the diagnostic significance of brainstem auditory evoked potential (baep) to brainstem ischemia or infarction.
前言:目的:探讨脑干听觉诱发电位(b aep)对脑干缺血、脑干梗死的诊断价值。
objective: to establish brainstem ischemic model and to observe earlier period ultrastructure of histology and pathology after brainstem ischemia in rats.
目的:制备脑干缺血动物模型并观察大鼠脑干缺血后早期组织学病理的超微结构。
result: 2 hours after brainstem ischemia ultra-early changes of pathology were observed, lesions of ischemia was aggravated gradually along with the prolongation of time.
结果:病理学观察发现脑干缺血2小时即可出现超早期病理变化,并随时间的延长缺血性损害逐渐加重。
