Figure 5.

The antioxidant enzyme activity (a) and ROS production (b) of AVA in lungs from mice with ALI. Tissue homogenates were prepared and subjected to western blotting using antibodies specific for SOD, catalase, and GPx. β-Actin was used as an internal control. The BALF was collected 6 h following LPS challenge to analyze ROS production. The data are presented as the mean ± SD for three different experiments performed in triplicate. ^###Compared with the control group. ^∗∗ p < 0.01 and ^∗∗∗ p < 0.001 compared with the LPS-alone group.
