摘要: 目的 探讨氧化苦参碱治疗哮喘的抗炎作用机制及其对细胞间黏附分子-1(ICAM-1)mRNA表达的影响.方法 建立小鼠哮喘模型,观察氧化苦参碱对哮喘小鼠支气管肺泡灌洗液中细胞总数、肺组织病理的影响,并应用半定量反转录-聚合酶链反应法检测肺组织中ICAM-1 mRNA表达的变化.结果 1)氧化苦参碱可显著减轻哮喘小鼠气道及肺组织中炎性细胞的浸润;2)氧化苦参碱显著抑制哮喘小鼠肺组织中ICAM-1 mRNA表达,此作用与其降低气道炎性细胞的浸润有关.结论 氧化苦参碱对哮喘小鼠有明显的抗炎及抑制其ICAM-1 mRNA表达的作用.

Abstract: Objective To explore the mechanism of oxymatrine anti-inflammatory and on ICAM-1 mRNA expression.Methods Established a murine model of asthma,investigated the effects of oxymatrine on the total cell number of bronchoalveolar lavage fluid(BALF) and histologic examination,and ICAM-1 mRNA expression by semiquantitative reverse transcription-polymerase chain reaction(RT-PCR) in asthmatic mice.Results 1) Oxymatrine can significantly reduced the total cell number of BALF and markedly improved peribronchial eosinophilic infiltration;2) ICAM-1 mRNA expression was significantly inhibited by oxymatrine,and this may contribute to its antiinflammatory effects.Conclusion Oxymatine can significantly anti-inflammatory and markedly inhibited ICAM-1 mRNA expression in asthmatic mice.

Key words: oxymatrine, asthma mouse model of asthma, anti-inflammatory, cell adhesion molecule
