目的探讨颈交感神经阻滞(SB)对烧伤大鼠蓝斑神经元电生理变化的影响。方法成年健康雄性Wistar大鼠20只,随机分为4组,对照组、对照SB组、烧伤组和烧伤SB组,每组5只。总体表面积(total body surface area,TBSA)20%Ⅲ度大鼠烧伤模型,4h后...目的探讨颈交感神经阻滞(SB)对烧伤大鼠蓝斑神经元电生理变化的影响。方法成年健康雄性Wistar大鼠20只,随机分为4组,对照组、对照SB组、烧伤组和烧伤SB组,每组5只。总体表面积(total body surface area,TBSA)20%Ⅲ度大鼠烧伤模型,4h后观察蓝斑神经元放电,HE染色组织学定位,免疫组织化学方法验证。结果在放电频率、放电脉冲间隔(ISI)、众数和不对称指数(AI),对照组和对照SB组比较差异无统计学意义(P>0.05);烧伤组和烧伤SB组放电频率显著高于对照组和对照SB组(P<0.01),而烧伤组又显著高于烧伤SB组(P<0.01);烧伤组和烧伤SB组ISI和众数显著高于对照组和对照SB组(P<0.01),而烧伤SB组又显著高于烧伤组(P<0.01);烧伤组和烧伤SB组AI显著高于对照组和对照SB组(P<0.01),而烧伤SB组和烧伤组间差异无统计学意义(P>0.05)。免疫组织化学方法显示蓝斑神经元主要为多巴胺β羟化酶(DβH)神经元。结论 SB对烧伤的治疗作用中枢机制之一可能是通过抑制蓝斑神经元放电活动来实现。展开更多
