摘要
目的研究痰热清注射液与头孢呋辛钠联用对金黄色葡萄球菌的体外抗菌作用。方法采用肉汤稀释法,测定痰热清注射液、注射用头孢呋辛钠分别对金黄色葡萄球菌的最低抑菌浓度(MIC);采用棋盘联合药敏试验法,测定痰热清注射液与注射用头孢呋辛钠联用对金黄色葡萄球菌的部分抑菌浓度(FIC)指数。结果痰热清注射液对金黄色葡萄球菌的最低抑菌稀释度是1∶256,注射用头孢呋辛钠对金黄色葡萄球菌的最低抑菌浓度是2μg·m L-1。两者联用时痰热清注射液对金黄色葡萄球菌的最低抑菌稀释度是1∶4 096,注射用头孢呋辛钠对金黄色葡萄球菌的最低抑菌浓度0.125μg·m L-1。痰热清注射液与注射用头孢呋辛钠联用对金黄色葡萄球菌的FIC指数是0.125。结论痰热清注射液联合头孢呋辛钠对金黄色葡萄球菌的药敏结果呈协同作用。
Objective To explore the in vitro antibacterial effect of tanreqing injection combined with cefuroxime sodium injection against staphylococcus aureus. Methods The MIC of tanreqing injection or cefuroxime sodium injection against staphylococcus aureus was detected by microamount dilution method.The antibacterial activity of tanreqing injection combined with cefuroxime sodium injection was determined by a chess board dilution method and assessed according to FIC index. Results The MIC of tanreqing injection and cefuroxime sodium injection against staphylococcus aureus was 1∶256 and 2 μg . mL-1 , respectively. While combined with each other, the MIC of tanreqing injection and cefuroxime sodium injection against staphylococcus aureus was 1∶4 096 and 0. 125 μg . mL-1 , respectively. The FIC index of tanreqing injection combined with cefuroxime sodium injection against staphylococcus aureus was 0. 125. Conclusion Tanreqing injection has a synergistic antibacterial effect against staphylococcus aureus when it was combined with cefuroxime sodium injection.
