目的 筛选九头狮子草治疗小鼠细菌性阴道炎的有效部位。方法 采用金黄色葡萄球菌、大肠埃希菌菌悬液注入小鼠阴道建立小鼠细菌性阴道炎动物模型,观察九头狮子草各极性部位对细菌性阴道炎的治疗作用。结果 九头狮子草水提液、石油醚提取部位和70%乙醇提取部位对病原菌转阴率和阴道黏膜炎症的治愈程度均有提高,其中,对金黄色葡萄球菌的转阴率分别为60%、50%、40%,对大肠埃希菌的转阴率分别为80%、70%、50%。结论 九头狮子草石油醚提取部位和70%乙醇提取部位为其治疗细菌性阴道炎的有效部位。

Objective To study the active parts of Peristrophe japonica of vaginitis treatment effect. Methods The bacterial vaginitis model was established by injecting the bacteria of Staphylococcus aureus and Escherichia coli into the vagina of the mice and the treatment effect of each extract of Peristrophe japonica was observed. Results Three drug administration groups (including water extract of Peristrophe japonica, ligarine fraction and 70% ethanol fraction) showed marked treatment effect on the vaginitis models. The effect of water extract of Peristrophe japonica group were stronger than that of the ligarine fraction and 70% ethanol fraction groups. The pathogens seroconversion rates in Staphylococcus aureus were orderly as follows: 60%, 50%, 40%. The pathogens seroconversion rates in Escherichia coli were orderly as follows: 80%, 70%, 50%. Conclusion The ligarine fraction and 70% ethanol fraction of Peristrophe japonica might be the active extracts of curing vaginitis.
