摘要:

为研究小型猪专用复合麻醉剂(XFM)对大鼠中枢神经系统c-myc mRNAiNOS mRNA转录的影响,将30只大鼠随机分为对照组(C组)和麻醉剂组(M组),M组又根据时间分为4个亚组:M1组(注射XFM后大鼠翻正反射消失即刻)、M2组(注射XFM后大鼠翻正反射消失后1 h)、M3组(注射XFM后大鼠翻正反射恢复即刻)和M4组(注射XFM后大鼠翻正反射恢复后1 h),各组大鼠到达预定的时间点后分别采取脑组织,应用实时荧光定量PCR技术检测中枢神经系统中c-myc mRNAiNOS mRNA转录量。结果显示,大鼠在应用XFM后,大脑皮层和丘脑c-myc mRNA的相对转录量在麻醉期间受到明显的抑制,与对照组相比差异极显著(P0.01),而小脑、海马和脑干c-myc mRNA的相对转录量在麻醉期间明显增加,与对照组相比差异极显著(P0.01);所有脑区iNOS mRNA的相对转录量在麻醉期间受到明显的抑制,与对照组相比差异极显著(P0.01)。结果表明XFM能够影响中枢神经系统中c-myc mRNAiNOS mRNA的转录,这可能是其产生麻醉作用的机理之一。

Abstract:

In order to investigate the transcription of c-myc mRNA and iNOS mRNA in central nervous system in rats anesthetized with the Combined
Anaesthetic for Miniature Pigs (named as XFM), 30 rats were divided randomly into two groups: control group and XFM group. XFM group consisted of four subgroups: M1 subgroup (rats received XFM intraperitoneally and then waiting the disappearance of right reflection); M2 subgroup (rats received XFM intraperitoneally and then waiting for 1 h after the disappearance of right reflection); M3 subgroup (rats received XFM intraperitoneally and then waiting the recovery of right reflection) and M4 subgroup (rats received XFM intraperitoneally and then waiting for 1 h after the recovery of right reflection). The brain tissues were taken when reaching each time point. The transcription of c
-myc mRNA and iNOS mRNA in central nervous system was detected with real time PCR. The results show that the transcription of c-myc mRNA in cerebral cortex and thalamus decreased significantly after receiving XFM (P0.01); The transcription of c-myc mRNA in cerebellum, hippocampus and brain stem increased significantly (P0.01). The transcription of iNOS mRNA in all brain regions decreased significantly after receiving XFM (P0.01). These results indicated that XFM could affect the transcription of c-myc mRNA and iNOS mRNA in central nervous system. This might be one of the anaesthetic mechanisms for XFM.
