The protective effect of oxygen radical scavengers on lung injury induced by activated eosinophils was examined in isolated perfused rat lungs. Eosinophils were obtained by bronchoalveolar lavage from rats infected with Toxocara canis and activated with phorbol myristate acetate (PMA). There were no changes in pulmonary vascular (RT) and airway (Raw) resistances and only minimal changes in vascular permeability assessed using the capillary filtration coefficient (Kf,c) in PMA control lungs and nonactivated eosinophil-treated lungs. In lungs receiving 3 x 10(6) PMA-activated eosinophils, there were significant increases from baseline of 7.3-fold in RT at 30 min, primarily due to the constriction of small arteries and veins; 3.6-fold in Kf,c at 90 and 130 min; and 2.5-fold in Raw. The lungs also became markedly edematous. Both superoxide dismutase and catalase pretreatment prevented the significant increase in Kf,c and lung wet-to-dry weight ratios and partially attenuated the increase in Raw, but did not significantly inhibit the increase in RT induced by activated eosinophils. Heat-inactivated catalase did not attenuate the eosinophil-induced increases in Kf,c, Raw, or RT. Thus, activated eosinophils acutely increased microvascular permeability primarily through production of oxygen free radicals. The free radical scavengers superoxide dismutase and catalase partially attenuated the bronchoconstriction but had no significant effect on the vasoconstriction induced by activated eosinophils.
