摘    要:目的探索大鼠鞘内注射艾司洛尔能否抑制福尔马林大鼠脊髓背角c-fos蛋白表达。方法雄性SD大鼠,鞘内置管成功后,随机分为三组(n=8):生理盐水组(N组),艾司洛尔300μg/kg组(E1组),艾司洛尔600μg/kg组(E2组)。在异氟醚麻醉下,鞘内注射上述药物10μl,5 d后,所有大鼠一侧后肢爪掌背侧皮下注射福尔马林(5%,50μl),观察大鼠在Ⅰ相(0~5 min)和Ⅱ相(15~50 min)疼痛行为学变化(包括添足、咬足、抬腿动作等),并进行Dubuisson评分。采用免疫组织化学方法检测脊髓背角c-fos蛋白表达。结果与N组比较,E1、E2组大鼠Ⅱ相阶段的疼痛相关行为均有减少,呈量效关系(P<0.05),且E1、E2组L4~5节段脊髓表达的c-fos蛋白均较N组减少(P<0.05)。结论鞘内注射艾司洛尔可减少福尔马林大鼠脊髓背角c-fos蛋白表达。

Abstract:Objective To investigate the effect of intrathecal esmolol on the expression of c-fos in the dorsal horn of spinal cord in a formalin-induced pain model.Methods Twenty-four SD rats were randomly divided into 4 groups with 8 each.Every mouse received intrathecal catheter placement and was infused with saline 10 L(group N),esmolol 300 g/kg(group A),or 600 g/kg(group B),respectively.Pain was induced by 50 L of 5% formalin solution injected into the dorsal surface of the right hind paw.The nociceptive behaviors...
