sarcoidosis/프롤린

BACKGROUND There is no known marker to screen patients with sarcoidosis to determine the risk of progression to pulmonary fibrosis. We aimed to identify potential noninvasive biomarkers for early detection of pulmonary fibrosing sarcoidosis. METHODS A case-control study was performed on African

We describe a new principle for the determination of enzymes, here applied to angiotensin-converting enzyme (ACE, EC 3.4.15.1) in human serum. The enzyme inhibitor binding assay is based on specific binding of labeled inhibitor to the active center of the enzyme. Serum (10-15 microL) is incubated

Because cells of the mononuclear phagocyte system are known to produce fibronectin and because alveolar macrophages are activated in many interstitial lung diseases, the present study was designed to evaluate a role for the alveolar macrophage as a source of the increased levels of fibronectin found

The functions of human pulmonary alveolar macrophages (PAMs) have been relatively little studied compared with those of their circulating counterparts, blood monocytes. This study examined the ability of human PAMs to kill primary human tumor cell cultures and control normal fibroblasts in vitro.
