2、组,健脾补肺化痰方高剂量、中剂量和低剂量组。以卵蛋白(OVA)致敏制备幼龄大鼠哮喘模型,HE染色测气道壁内、外径及网状基底膜层厚度,肺组织石蜡切片行免疫组化染色计算机图像分析测定气道Ⅰ、Ⅲ型胶原含量。结果:健脾补肺化痰方高、中、低剂量干预组、辅舒酮组气道壁内、外径比值均高于哮喘模型组,网状基底膜厚度较哮喘模型组显著变薄(P<0.05或P<0.01),健脾补肺化痰方高、中、低各组间比较亦有差异(P<0.05),健脾补肺化痰方高剂量组与辅舒酮组比较无明显差异(P>0.05)。各组气道壁Ⅲ型胶原显著低于哮喘模型组(P<0.05或P<0.01),高、中、低剂量组各组
3、间Ⅲ型胶原含量比较(P<0.05)依次增高。高剂量组与辅舒酮组Ⅲ型胶原含量相当(P>0.05)。结论:健脾补肺化痰方可以通过减少气道壁Ⅲ型胶原沉积和气道壁增厚而抑制气道重塑。关键词:健脾补肺化痰方;哮喘;胶原蛋白中图分类号:R562.2.5文献标志码:A文章编号:1673-842X(2015)01-0039-03JanpiBufeiHuatanFormulaforYoungAsthmaticRatAirwayWallCollagenSynthesis112YUYanling,BIANXun,SHANGLili(1.CombinedTraditionalChi
