FIG. 2.

Effect of IFN-γ treatment of PMNs for 45 min in vitro on activated NO release from PMNs. Cells were obtained from CGD patients (n = 3) or healthy volunteers (controls) (n = 2) and activated with fMLP at 1 μM. The release of NO was monitored continuously for 45 min by the HbO₂ method, as described in Materials and Methods. For each experimental condition, samples were run in duplicate. All values given are the l-NMMA-inhibitable responses and are expressed as means ± standard errors of the means. ∗∗, P < 0.001.
