摘要: 目的 观察碱性成纤维细胞生长因子在急性哮喘大鼠肺组织的表达情况及布地奈德的干预影响。方法 36 只雄性SD 大鼠随机分为对照组、哮喘组和布地纳德治疗组, 以卵清白蛋白激发法制备哮喘模型, 采用ELISA 法测定支气管肺泡灌洗液中碱性成纤维细胞生长因子的含量, 免疫组化和原位杂交法测定肺组织中碱性成纤维细胞生长因子蛋白和mRNA 的表达情况。结果 支气管肺泡灌洗液中的碱性成纤维细胞生长因子浓度、肺组织碱性成纤维细胞生长因子蛋白和mRNA 的表达水平哮喘组显著高于对照组(P<0.01) , 治疗组显著低于哮喘组(P<0.01) , 但与对照组相比仍较高(P<0.01) , 上皮细胞为主要表达细胞。结论 碱性成纤维细胞生长因子参与了哮喘的发病机制, 布地奈德可抑制哮喘急性期碱性成纤维细胞生长因子蛋白和mRNA 的表达增加效应, 这可能是布地奈德抑制哮喘气道重塑的重要机制之一。

Abstract: AIM: To investigate the effects of budesonide on expression of basic fibroblast growth factor and mRNA in asthmatic rats.METHODS: Thirty six male Sprague-Dawley rats were randomly divided into three equal groups, including asthma group, control group and budesonide treatment group.In this experiment, the rat model of asthma was established by the ovalbumin challenge methods.The concentration of basic fibroblast growth factor in bronchoalveolar lavage fluid(BALF) was measured by ELISA, the expression of the protein of basic fibroblast growth factor and mRNA were detected with immunohistochemistry methods and in situ hybridization methods.RESULTS: The concentration of basic fibroblast growth factor in bronchoalveolar lavage fluid, the protein and mRNA expression of basic fibroblast growth factor in lung tissue were significantly higher in the asthma group than those of control group (P<0.01) , it was much lower in the treatment group than that in the asthma group, but it was still higher than the control group.The epithelial cell is the chief expression cell.CONCLUSION: The basic fibroblast growth factor participates in the pathogenesis of asthma, inhaled budesonide can significantly inhabit the expression of the protein and mRNA of basic fibroblast growth factor in the acute stage of asthma,and prevent the airway remodeling.

Key words: asthma, basic fibroblast growth factor, budesonide, rat
