Flow cytometric analysis of active oxygen generation in neutrophils.

Histograms of DHR-123 fluorescence as indicative of active oxygen generation in neutrophils are shown. Neutrophils were obtained from patients 1, 2, and 3 or from control (Cont) before (solid and dotted line) or 25 days after (bold solid line) IFN-γ administration. Profiles of the cells stimulated with PMA are shown with a solid or bold solid line.
