Evaluation of In Vitro Anti-Inflammatory Activities and Protective Effect of Fermented Preparations of Rhizoma Atractylodis Macrocephalae on Intestinal Barrier Function against Lipopolysaccharide Insult
Figure 8
The effect of treatment with LPS in combination with saline (LC) or with two different concentrations of fermented Rhizoma Atractylodis Macrocephalae-1 (FRAM-1) and fermented Rhizoma Atractylodis Macrocephalae-2 (FRAM-2) formulations on production of TNF-α (a), IL-1β (b), and IL-6 (c) by RAW264.7 cells. The cells were treated for 24 h with the indicated concentrations of FRAMs. The control cells (N) and the noncontrol cells that were assigned to treatment with LPS alone (LC) were treated with sterile saline instead of herbal extracts. After this treatment, the noncontrol and control cells were treated with LPS (10 μg/mL) and PBS, respectively, for 24 h; production of the above-mentioned cytokines was then determined. The detailed treatment regimen and experimental conditions are described in Section 2. The values are expressed as the mean ± SD, . The data for expression of the IL-6 gene were log-transformed prior to analysis by ANOVA. significant difference compared to control cells (); significant difference compared to cells treated with LPS plus saline (); lower compared to all other treatment groups ().
