摘要: 目的:研究异丙酚不同麻醉深度对兔脑海马c-fos mRNA 水平的影响。方法:30 只日本大耳兔,随机分为3 组, 即对照组, 浅麻醉组, 深麻醉组。浅麻醉组, 深麻醉组予以异丙酚靶控输注(TCI) 达到所需麻醉状态30 min 后断头处死, 0 ~ 4 ℃ 分离取脑, 采用原位杂交法测定海马各区c-fos mRNA 表达水平。结果:与对照组比较, 海马CA1 区, 齿状回(DG) 区c-fos mRNA 表达水平随着麻醉深度的增加而显著升高(P <0.05) 。海马CA3 区未见明显变化。结论:异丙酚可能通过影响c-fos mRNA 的表达, 从而影响随后反应基因的转录而发挥抑制中枢的作用且此作用存在区域性差异。

Abstract: AIM: To research alterations of c-fos mRNA in rabbit hippocampus during propofol anesthesia. METHODS: 30 rabbits randomly allocated into 3 groups:control group, shallow anesthetic group and deep anesthetic group.Each group had 10 rabbits.The expression levels of c-fos mRNA in different anesthetic depths in hippocampal CA1, CA3, and DG were observed using target-controlled infusion of propofol.RESULTS: As the anesthetic depth increased, the levels of c-fos mRNA in hippocampal CA1 and DG increased significantly compared with control group.The levels of c-fos mRNA in hippocampal CA3 had no significant change in all groups. CONCLUSION: Propofol affects the expression of c-fos mRNA, subsequently influences fos-related gene transcription and its anesthetic action.The influence differs in different brain regions.

Key words: propofol, target-controlled infusion, anestheticdepth, c-fos, hippocampus
