RESUMO
OBJECTIVE: To observe the effects of xipayi mouth rinse on the DNA synthesis and change of cell cycles of human gingival fibroblast (HGF) induced by lipopolysaccharide(LPS). METHODS: HGF was stimulated with LPS at 25 mg/L. Flow cytometry was used to examine the effect of xipayi mouth rinse at 25 mg/L on the DNA synthesis and change of HGF cell cycles. RESULTS: The percentage of HGF in G( 1) phase increased after the cells were induced by LPS, while the percentage of HGF in S phase decreased. Xipayi mouth rinse could ameliorate this phenomenon. CONCLUSION: Xipayi mouth rinse can significantly ameliorate the inhibitory effect of LPS on the proliferation of HGF, suggesting the anti-inflammatory effect of xipayi mouth rinse in the treatment and prevention of periodontal diseases.

OBJECTIVE: To observe the effects of xipayi mouth rinse of different concentrations on the activities of interleukin-6 (IL-6) from human gingival fibroblast (HGF) induced by lipopolysaccharide (LPS). METHODS: HGF was stimulated with LPS at 25 g/mL, and the radioimmunoassay (RIA) was used to examine the effect of xipayi mouth rinse at 12.5 approximately 200 g/mL on the secretion of IL-6 in the supernatant of the cell culture. RESULTS: IL-6 secreted by human gingival fibroblast was significantly inhibited by xipayi mouth rinse in a dose dependent manner. CONCLUSION: Xipayi mouth rinse can inhibit the secretion of IL-6 from HGF induced by LPS, suggesting the anti-inflammatory effect of xipayi mouth rinse to treat and prevent periodontal diseases.
