(A) Effects of exopolysaccharide on LPS-induced NO production. RAW 264.7 cells were pretreated with polysaccharide (50–200 μg mL⁻¹) for 1 h before incubation with LPS (100 ng mL⁻¹) for 16 h; (B) Effects of exopolysaccharide on LPS-induced 5-LOX production. RAW 264.7 cells were pretreated with polysaccharide (50–200 μg mL⁻¹) for 1 h before incubation with LPS (100 ng mL⁻¹) for 16 h; (C) Effects of exopolysaccharide on LPS-induced iNOS mRNA levels in RAW 264.7 cells. The cells were pretreated with the polysaccharide for 1 h before incubation with LPS (100 ng mL⁻¹) for 16 h and total RNA was extracted. iNOS mRNA were measured by PR-PCR using specific primers. The bars labeled with the same letters are not significantly different at p < 0.05.
