Preventive Effects of a Kampo Medicine, Kakkonto, on Inflammatory Responses via the Suppression of Extracellular Signal-Regulated Kinase Phosphorylation in Lipopolysaccharide-Treated Human Gingival Fibroblasts
Effects of kakkonto on the production of PGE2, IL-6, and IL-8. HGFs were treated with combinations of LPS (0 and 10 ng/mL) and kakkonto (0, 0.01, 0.3, 0.1, 0.3, and 1 mg/mL) for 24 h. Concentrations of PGE2 (a), IL-6 (b), and IL-8 (c) were measured by ELISA, adjusted by cell number, and expressed as per 10,000 cells (mean ± SD, ). Open circles, treatment without LPS; closed circles, treatment with 10 ng/mL of LPS. and (without kakkonto versus with kakkonto). (without LPS versus with LPS). values were calculated by pairwise comparisons and corrected with the Holm method (16 null hypotheses).
