Abstract:Objective: To observe the effect on infantile allergic cough with Minkeqing oral liquid (Minkeqing) and to study its cell molecular biologic mechanism. Method: The rat model was induced by inhalating ovalbumin; then the effects of Minkeqing on IL-6, IL-8, ET-1, TX-B2 in the blood and the bronchoalveolar lavage fluid (BALF) of the animal model were obsered. Result: Minkeqing could reduce the levels of IL-6,IL-8,ET-1 .Tx-B2 in the blood and BALF of the animal model. Conclusion: Minkeqing has the significant function of inhibiting the release of inflammatory mediums.
