Figure 3

Ex vivo release of H2O2 from PMA-stimulated BAL cells. BAL cells, obtained from rats exposed to non-coated DQ12 or DQ12 coated with PVNO or AL (7 days after i.t. instillation) were cultured in vitro (4 h) with or without PMA (100 ng/ml) to activate their oxidative burst. The graph shows the ratio between spontaneous and PMA-induced H2O2 production, which is expressed as % increase. Data are presented as mean ± SD (n = 3). *p < 0.01 vs. PBS.
