title: Lipid metabolism in rabbits exposed to paraquat aerosol.
abstract: In order to examine the effects of paraquat on pulmonary lipid metabolism rabbits were exposed to double distilled water by aerosol, or 250 mg paraquat in double distilled water. One hour prior to sacrifice, a group of rabbits were injected with [2-14C]-acetate. The levels of phospholipids, fatty acids, cholesterol, and triglycerides were determined as were their 14C-contents in the lung, bronchoalveolar lavage fluid, serum, and liver. The serum of paraquat-exposed animals contained significantly increased levels of phospholipids, cholesterol, and triglycerides. Liver, lung, and bronchoalveolar lavage contained less than or equal to control levels of phospholipids, cholesterol, and triglycerides. Percent of palmitate in the hepatic fatty acid profile was slightly increased in liver but not in lung. The source of the increased lipids in the serum is unknown.
