咽炎浓煎剂体外抗菌作用研究

Study of External Antisepsis on Decoction for Pharyngitis

目的 :研究咽炎浓煎剂的体外抗菌作用。方法 :采用琼脂扩散法、连续稀释法 ,测定咽炎浓煎剂的抑菌圈和最低杀菌浓度 ( MBC)。结果 :咽炎浓煎剂对乙型溶血性链球菌、肺炎双球菌、金黄色葡萄球菌等致病菌均有明显的体外抗菌作用。结论 :咽炎浓煎剂对所有受试菌均有不同程度的抗菌作用 ,且抗菌谱较广 ,为临床治疗急慢性咽喉炎提供了佐证。

OBJECTIVE To study on antibacterial action of mistura Yanyan composita in vitro.Methods Using as agar diffusion tests and serial dilution tests,antibacterial cycle dimensions and minimal bactericidal concentration(MBC) of mistura Yanyan composita were observed.RESULTS The result of antibacterial experiment showed that mistura Yanyan composita could significantly inhibit test-bacteria such as β-hemolytic streptococcus,streptococcus pneumaniae,staphylococcus aureus in vitro.CONCLUSIONS mistura Yanyan composita was inhibitory drug and bactericide on all test-bacteria in different extent,and antibacterial spectrum was wide.
