[Effects of Fritillariae Cirrhosae Bulbus on MMP-2,MMP-9 and TIMP-1 in murine asthma model].

To investigate the effects of Fritillariae Cirrhosae Bulbus on airway remodeling and matrix metalloproteinase-2(MMP-2), matrix metalloproteinase-9(MMP-9), tissue inhibitor-1 of metalloproteinase(TIMP-1) of a murine asthma model, and explore its mechanism in treatment of asthma. BALB/C murines were randomly divided into the normal group, model group, high dose group, low dose group, and positive control group. Except for the normal group, all the other groups received ovalbumin(OVA) to establish murine asthma model.
