To further study the mechanism of blast trauma causing deafness. Methods: After shock wave, different groups of guinea pigs were studied by ABC immunohistochemistry, image analysis techniques and auditory brainstem response. 方法:对冲击波暴露后不同时间组采用免疫细胞化学技术(ABC)结合图像分析和听性脑干反应测试技术进行观测。
Head trauma and brain auditory evoked potentials 头部外伤后听觉脑干反应分析
Trauma of the eardrum was examined and auditory function was monitored by measuring the thresholds of auditory brainstem responses ( ABR) before and after noise exposures, and then the hair cells 'diversification of cochlea were anatomized after 1 week ′ s noise exposure. 检测噪声暴露前后中耳损伤、ABR听阈及1周后的毛细胞变化。
