acoustic trauma could decrease gr expression in all positions of cochlea, particularly in spiral ligament and stria vascularis.
声损伤降低耳蜗各区域gr的表达,以血管纹、螺旋韧带最明显。
objective:to observe the protective effect of sound preconditioning on hearing in acoustic trauma and explore the relevant mechanism with regard to free oxygen radicals in the cochlea.
目的:观察声预处理对噪声性听力损失的保护作用,并从氧自由基途径探讨其机制。
there was a possibility of acoustic trauma in the artillerymen with late—onset tinnitus or deafness.
晚期出现耳聋、耳鸣癥状的炮兵,有听力损伤的潜在可能。
this is an experimental research into acute acoustic trauma free entirely from any explosive factor.
