Effect of ERI on inflammatory cytokine levels in vivo and in vitro. (A) Rats were given an intragastric injection of ERI (20 and 40 mg/kg) once a day for 4 weeks after the immunized again. The concentrations of IL-1β, IL-6 and TNF-α were determined in serum. (B) RAW264.7 cells were treated with LPS. The concentrations of IL-1β, IL-6 and TNF-α were determined in culture supernatant. Values represent the mean ± SD and are representative of two independent experiments. ##P < 0.01 versus control group; *P<0.05, **p < 0.01, versus CIA group.
