Figure 4: Effect of PG extracts on mRNA expression of pro-inflammatory or allergic cytokines, and on the number of inflammatory cells. (A) Photographs for mRNA expression of pro-inflammatory cytokines (IL-1β, IL-6 and TNF-α) or allergic inflammatory cytokines (IL-4, IL-5, IL-13r1a and IL-13r2a) in NC/Nga to evaluate theraputic effect for PG. Normal control (NC), postive control (PC), PG (DNCB + PG 500 mg/kg), DEX (DNCB + dexamethasone 1.5 mg/kg) (B) Graph represents the number of immunopostive cells for ED1, CD3 and HLA-DR. *P < 0.01 vs. PC.
