ABSTRACT

OBJECTIVE:

To investigate the effects of extract of Ginkgo biloba(Egb761) on the expression of matrix metalloproteinase-9(MMP-9) and tissue inhibitor of metalloproteinase-1(TIMP-1) and evaluate its intervention effect on airway remodeling in asthmatic rats model.

METHODS:

Rats were randomly assigned to normal control, asmatic group, Dexamethasone (DXM) group and Egb761 group. The asmatic model was established in rats. The changes of airway morphologic parameter and the relative content of MMP-9 and TIMP-1 in bronchial epithelium in these groups were determined using immunohistochemical technique and computer assisted image analysis system.
