As expected, 28 days after successful modeling, the levels of inflammatory mediators and oxidative stress markers in the lung tissue of rats in the BLM group were increased, while CAT reduced the levels of IL-1β (Figure 7A), TNF-α (Figure 7B), IL-6 (Figure 7C), MDA (Figure 7D), and ROS (Figure 7E) and increased the activity of SOD (Figure 7F) in the lung tissues of IPF rats. Here, IL1B is linked to idiopathic pulmonary fibrosis.
