2、大鼠用机械缩足反射阈值(MWT)和热缩足潜伏期(TWL)来分别评价大鼠机械痛敏和热痛敏。SD大鼠随机分为5组,即假手术组(Sham组)、CCI组和空白组,生理盐水组(NS组)和芍药甘草汤组(SGM组),各组分别在术前和术后第1、3和7d分别测定MWT和TWL,手术结束后提取大鼠脊髓后角测定IL-6、IL-1β、TNF-α的水平。结果:和空白组及Sham组相比,CCI组和NS组术后MWT及TWL均明显下降(P<0.01)。SGM组与NS组相比,MWT和TWL在术后1、3和7d均明显增加(P<0.01)。和空白组和Sham组相比,CCI组和NS组IL-
3、6、IL-1β、TNF-α的水平明显增加(P<0.01)。和NS组比较,SGM组IL-6、IL-1β、TNF-α的水平明显降低(P<0.01)。结论:SGM能抑制CCI大鼠的机械痛敏和热痛敏作用,其镇痛作用可能和减少IL-6、IL-1β、TNF-α的水平有关。关键词:芍药;甘草;神经病理性疼痛中图分类号:R285.5文献标志码:A文章编号:1673-7717(2013)04-0801-03AdministrationoftheInfluenceofShaoyaoGancaoDecoctionExtractsonIL-6IL-1βandTNF-αin
