Effects of NF161 and NF177 on FMLP-evoked O₂^-. production by PMNs. The results are expressed as percentage inhibition of O₂^-. production evoked by 10^-7M FMLP in the absence of NF161 and NF177: this production amounted to 2.1 ± 0.3 nmol cytochrome C reduced/10⁶ cells/min and was taken as 100%. Data are expressed as means ± SEM; n = 5. Asterisks mark statistically significant inhibition of NF161 versus NF177 (**P < 0.01).
