Objective:To explore the effect of Ravan Napas on the expression of ICAM 1 and HO 1 on broncho epithelial cells of asthmatic rats.

目的：研究维药纳气平喘颗粒对哮喘大鼠支气管上皮细胞细胞间粘附分子(ICAM 1)和血红素氧合酶 1(HO 1)表达的影响，以阐明纳气平喘颗粒治疗哮喘病的部分作用机制。

Ravan Napas can reduce the expression of ICAM 1 and HO 1 on broncho epithelial cells and thus inhibits the aggregation of the inflammatory cells and the release of the inflammatory media, as a result leads to less inflammation of bronchia. Such inhibitory way might be one of the possible mechanisms of Ravan Napas in treating asthma.

纳气平喘颗粒通过调节支气管上皮细胞ICAM 1和HO 1的表达，可抑制炎性细胞在气道内聚集及其炎性介质的释放，减少气道变应性炎症，这可能是纳气平喘颗粒治疗哮喘病的部分机制。
