bronchoalveolar lavage fluid
The accumulation in the submucosa of fibrous proteins that are substrates of       matrix metalloproteinases (MMP), and the demonstration of increased levels of       MMP-9 in bronchoalveolar lavage fluid, prompted us to determine whether there was       an imbalance between MMPs and tissue inhibitors of metalloproteinase (TIMP) in       such patients.
