Figure 2. Baicalein reduces OVA-induced Th2 inflammation. The OVA/Al(OH)3 model is characterized by Th2-driven airway inflammation. To determine the effect of Baicalein on Th2 airway inflammation, ELISA was performed to detect the levels of IgE in serum (A) and IL-4, IL-5, and IL-13 in BALF (B–D) and lung homogenate (E–G) (results are presented as the mean ± SEM. n = 6 mice per group; ##P < 0.01 compared with the control group; *P < 0.05, **P < 0.01 compared with the OVA/Vehicle group).
