Cytotoxic effect of BT. (a) RAW 264.7 cells were treated with varying amounts of BT for 16 h. The cytotoxicity induced by BT was measured by MTT assay. Data are shown as the mean ± SEM of three independent measurements. There was no statistical difference among different groups. (b) RAW 264.7 cells were treated with LPS (100 ng/ml) or BT (50 μg/ml) for 16 h. Cells producing intracellular ROS were determined by a flow cytometer. The percentile of ROS-positive cells is shown in the upper right side of each panel. All experiments were repeated three times independently and representative results are shown.
