喉咽灵口服液的体外抗菌作用

Studies on antibacterial action of compound Houyanling oral solution in vitro

目的 :探讨喉咽灵口服液的体外抗菌作用。方法 :以临床分离细菌为受试菌 ,采用连续倍比稀释法 ,观察喉咽灵口服液的最低抑菌浓度和最低杀菌浓度。结果 :喉咽灵口服液对不同细菌的最小抑菌浓度是成品浓度 64～ 1 2 8倍 ,最小杀菌浓度是成品浓度 32～ 64倍。结论 :喉咽灵口服液对所有受试菌均有不同程度的抑菌和杀菌作用 ,且抗菌谱广 。

OBJECTIVE To study on antibacterial action of compound Houyanling oral solution in vitro .METHODS Using as test bacteria isolated from clinic, minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of compound Houyanling oral solution were observed.RESULTS MIC of compound Houyanling oral solution was 64 to 128 times and MBC was 32 to 64 times,respectively.CONCLUSIONS Compound Houyanling oral solution was inhibitory drug and bactericide on all test bacteria in different extent, and antibacterial spectrum was wide.
