To examine the inhibitory effects of BAW on the expression of Th2-like and pro-inflammatory cytokines, the levels of IL-4, IL-13, TNF-α, and IL-1β were measured in the lung tissue, BALF, and serum of an OVA-induced asthma model treated with BAW using real-time PCR and ELISA. The gene discussed is TNF; the disease is asthma.
