We studied the effects of oleic acid (OA) on pulmonary clearance of three aerosolized radioactive solutes: 99mTc-diethylenetriamine pentaacetate (99mTc-DTPA), 67Ga-desferoxamine (67Ga-DFOM), and 111In-transferrin (111In-TF). Either 0.09 ml/kg OA or an equivalent volume of 0.9% NaCl (controls) was administered intravenously to 48 anesthetized, paralyzed dogs. Each animal received one aerosolized solute either 60 min after (protocol A) or 30 min before (protocol B) the infusion of OA or NaCl. In protocol A clearances of all three solutes were similar in OA and control animals. In contrast, in protocol B clearances of all three solutes increased significantly during OA infusion; during the next 60 min clearances of 99mTc-DTPA and 67Ga-DFOM returned to control values but 111In-TF remained increased. We conclude that 1) in OA-induced permeability edema pulmonary clearance of aerosolized solutes is increased when the aerosol is delivered 30 min before but not 60 min after injury, and 2) increased clearance persists only for large molecules, presumably because smaller molecules cross injured epithelium quickly and completely. These phenomena are best explained by a nonhomogeneous distribution of OA-induced injury.
