摘要
为了了解+ GZ 重复暴露后大鼠脑组织一氧化氮合成酶(NOS)基因表达的变化,探讨+ GZ引起脑损害的分子机制,本文用建立的定量反转录聚合酶链反应(RT-PCR)检测方法检测+ GZ 重复暴露后大鼠脑组织内NOSm RNA 表达的变化。结果+ GZ 重复暴露后 30 m in 和 6 h 大鼠脑组织NOSm RNA明显升高,但 24 h 时恢复正常,表明+ GZ 重复暴露可刺激大鼠脑组织 NOSm RNA 的表达,NO可能参与了+ GZ 所致脑损害的病理过程,但这种损害是可逆的。
To explore the molecular mechanism of repeated +G Z exposures induced brain damage, the mRNA expression level of nitric oxide synthase (NOS) in rat brains removed 30 min, 6 h and 24 h after repeated +G Z exposure was measured by quantitative reverse transcription polymerase chain reaction (RT PCR).The results showed the NOS mRNA expression level in rat brain of 30 min and 6h after repeated +G Z exposures obviously increased, but returned to the normal level in 24h. It is suggested that the NOS mRNA expression in rat brain was stimulated by repeated +G Z exposures and NO may play a role in the pathologic course of +G Z exposures induced brain damage, but the damage is reversiable.
