Research Abstract |
Bronchoalveolar lavage fluid (BALF) is used for diagnosis and determining clinical condition in interstitial pneumonia, but the relations between BAL lipid composition and clinical condition are unclear. We developed an assay for determining lipid species, fatty acid composition, and lipid metabolic enzyme activity using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and gas chromatography mass spectrometry. The methods were rapid, simple, and accurate with very small samples. The BALF phospholipid profile was determined by mass spectrometry. We could detect changes in metabolism of phospholipid species in BALF by comparing the phospholipid profile of the serum with BAL. The results may be useful as an index to determined phospholipid metabolic disorders in pulmonary surfactant and alveolar cells.
