【摘要】 目的研究清喉口含片的体内、外抑菌作用。方法采用标准试管二倍稀释法测定清喉口含片的最低抑菌浓度(MIC)和最低杀菌浓度(MBC),并观察清喉口含片在小鼠体内对金黄色葡萄球菌的抑菌作用。结果清喉口含片对金黄色葡萄球菌、甲型溶血性链球菌、乙型溶血性链球菌、肺炎链球菌、流感嗜血杆菌均有明显的体外抑制作用,其MIC、MBC分别为0.0625~0.50、0.125~1.0g/ml,对腹腔注射金黄色葡萄球菌的小鼠具有抑菌作用。结论清喉口含片具有体内、外抑菌作用。更多还原

【Abstract】 OBJECTIVE: To study the antibacterial actions of Qinghou buccal tablets in vivo and in vitro. METHODS: Minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of Qinghou buccal tablets were determined by standard test tube doubling dilution method;And the antibacterial action of which on staphylococcus aureus in mice in vivo were monitored. RESULTS: Qinghou buccal tablets had significant in vitro antibacterial action on staphylococcus aureus, α-hemolytic streptococcus, β-hemolytic streptococcus, streptococcus pneumoniae and hemophilus influenza, with MIC and MBC at 0.0 625～0.50g/ml and 0.125～1.0g/ml, respectively,and which had bacteriostatic action on mice that injected i.p. with staphylococcus aureus. CONCLUSION: Qinghou buccal tablets were proved to be of bacteriostatic actions in vitro and in vivo.更多还原
