Fig. 4From: Astilbe Chinensis ethanol extract suppresses inflammation in macrophages via NF-κB pathwayEffects of ACE production of inflammatory mediators in stimulated primary peritoneal macrophages. Thioglycollate (3%), rIFN-γ (10 U/mL), and LPS (1 μg/mL)-stimulated primary peritoneal macrophages were incubated for 48 h. a NO and (b) PGE2 level were measured with Griess reagent and the EIA kit, respectively. NIL (20 μM) or NS398 (5 μM) was used as positive control. Values are presented as mean ± S.D. of three independent experiments. ###p < 0.001 when compared with control; *p < 0.05, ***p < 0.001 when compared with LPS-induced group. Significant differences between treated groups were determined by ANOVA and Dunnett’s post hoc testBack to article page
