摘要
目的 研究不同天然药物对粘性放线菌生长及产酸的影响 ,为筛选能有效调理口腔菌群生态平衡的药物奠定基础。方法 选用粘性放线菌标准株 ATCC 192 46作为实验菌株。测定川芎、血藤和五倍子等十一种天然药物的最低抑菌浓度 (MIC)。再以低于 MIC的 4个浓度配制含药的 TPY液体培养基 ,调定其初始 p H为 7.4,接种粘性放线菌 ,厌氧培养后测定其终末 p H。结果 当药物浓度低于或等于 8.0 0 0 mg/ ml时 ,除三七外 ,其他药物对粘性放线菌的生长都有一定的抑制作用 ,且以槟榔和蜂房较强。茶多酚、三七、大黄、蜂房和血藤对粘性放线菌的产酸具有一定的抑制能力 ,而黄芩、槟榔、川芎、五倍子、白芷和儿茶没有明显的抑制作用。结论 茶多酚、大黄。
Objective To assess the effects of different natural medicines on the growth and acid production of Actinomyces viscosus, thus making preparations for screening an effective agent to mediate the balance of oral microflora. Methods Actinomyces viscosus ATCC 19246 was chosen as the experimental bacteria. 11 kinds of traditional Chinese medicine, such as Rhizoma Ligustici Chuanxiong, Sargentodoxa Cuneata and Galla Chinensis were extracted by means of maceration, percolation and reflux extraction. First, the values of MIC of various extracts were measured. Second, the experimental medium containing various extracts was prepared. The concentration of the extracts was lower than the MIC of the medicine, and the initial pH of the medium was 7.4. Then Actinomyces viscosus was cultured in the medium for 48h, and finally the rest pH was measured. Results When the concentration of the medicines was lower than or equal to 8.000mg/ml, it was found that all kinds of medicine except Radix Notoginseng can inhibit the growth of Actinomyces viscosus effectively, especially Polistes mandarinus and Semen Arecae. Tea polyphenols, Radix Notoginseng, Radix et Rhizoma Rhei, Polistes mandarinus and Sargentodoxa cuneata can inhibit the acid production of Actinomyces viscosus effectively, but Radix Scutellariae, Rhizoma Ligustici Chuanxiong, Semen Arecae, Radix Angelicae Dahuricae, Galla Chinensis and Catechu have no preliminary effect on it. Conclusion Tea polyphenols, Radix et Rhizoma Rhei, Polistes mandarinus and Sargentodoxa cuneata can inhibit the growth and the acid production of Actinomyces viscosus effectively.
