Effects of FBL on TNF-α levels in LPS-stimulated RAW 264.7 cells. Control group treated without LPS and FBL; model group treated with only 1 μg/mL LPS for 24 h; positive group treated with 44.70 mg/mL indometacin for 6 h and 1 μg/mL LPS for 24 h; and FBL groups treated with 62.50, 15.62, and 3.91 μg/mL FBL for 6 h, respectively, and 1 μg/mL LPS for 24 h. and versus model group. versus medium-dose FBL group.
