Effects of CAM pretreatment on SOD activity in H2O2-stimulated SAECs. SOD activities were assessed by measuring formazan production at 450 nm as described in the Methods. Samples were obtained from supernatants of control cells, of cells stimulated with 100 μM H2O2 alone, or of cells pretreated with 1, 5 or 10 μM CAM for 72 h before stimulation with 100 μM H2O2 for 1.5 h. Data are presented as means ± SD of three to six independent experiments. **p < 0.01 vs. control cells, ##p < 0.01 vs. cells stimulated with H2O2 alone, p < 0.05 vs. cells pretreated with 10 μM CAM
