title: BAL fluid LDH activity and LDH isoenzyme pattern in lipoid pneumonia caused by an intravenous injection of lamp oil.
abstract: A 30 year old man developed lipoid pneumonia after an injection of lamp oil. In addition to "foamy" alveolar macrophages, bronchoalveolar lavage (BAL) fluid analysis showed an increased number of neutrophils. Moreover, lactate dehydrogenase (LDH) and alkaline phosphatase activities were elevated. The increase seen in LDH activity both in serum and BAL fluid was accompanied by shifts in the isoenzyme pattern in similar directions for both fluids. These findings suggest a pulmonary source for the temporary serum as well as BAL fluid LDH increase. This case indicates the usefulness of bronchoalveolar lavage fluid analysis as a probe to detect pulmonary injury caused by a pneumotoxicant and, probably, to monitor recovery or deterioration.
