Intracellular Superoxide. Dose response for PMA stimulation of intracellular oxidative activity of circulating neutrophils 18 hours after administering to ovalbumin (OA)-sensitized rats naïve bovine serum albumin (BSA) (□ n = 7), sensitizing OA antigen (○, n = 7), feG (■ n = 7), or OA + feG (●, n = 6). Oxidative activity was measured using flow cytometry for a marker of oxygen free radicals (123-dihydrorhodamine), and is expressed as mean fluorescence intensity (MFI). Significance: # < feG & OA; ## > all other groups.
