FBL treatment duration of RAW 264.7 cells. Control groups were treated without LPS and FBL, model groups were treated with only 1 μg/mL LPS, and FBL groups were treated with 1 μg/mL LPS and 62.50 μg/mL FBL. : FBL group versus model group during the same treating time. : model group versus control group during the same treating time.
