Objective:Observed the relative content of plasma MMP-9 and TIMP-1, the change of plasma TGF-β1 and lung morphology in Balb/c mice, so as to explore the effect and mechanism of Huoxue Dingchuan Soup(HDS) to MMP-9/TIMP-1 balance and asthmatic airway remodeling.
Methods:Balb/c mice 70 were randomly divided into normal group, model group, western medicine group, HDS low-dose group and high-dose group. Asthmatic airway remodeling model was established by repeated inhalation of ovalbumin. The normal group an...
