为探讨豚鼠耳蜗核一氧化氮合酶（nitricox山esynthase,N（）引神经元在白噪声损伤过程中可能的作用,采用硫辛酗胺脱氢酣（NAII,HA）组织化学方法及半定量多聚酶链反应（PCR）技术,研究白噪声暴露后豚鼠耳蜗核N（B神经元及N（）SmRNA含]IZ的变化以及与听阈的关系.结果表明,噪声
To investigate the possible role of neurotrophic nitric oxide synthase (N (¢ ö)) -induced cochlear nucleus damage during white noise in guinea pig cochlear nuclei, the histochemical method of NAII (HA) and semi-quantitative Polymerase chain reaction (PCR) technique was used to study the changes of N (B neuron and N (subscript Sm) mRNA IZ) and the relationship with hearing threshold in guinea pig cochlear nucleus after white noise exposure.The results showed that noise
