  1. Cytokine levels in culture medium were measured by ELISA. Drug concentrations are the IC50 for TNFα for each drug. Results are expressed as absolute level (ng/ml) and as percentages of cytokine activity and represent the mean ± SEM of five experiments done in triplicate.
  2. aPercentage activity.
  3. bSignificant (p < 0.05) difference compared with control values.
