The antibacterial effects of ethanol extract of Rhynchosia volubilis Lour roots on staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and pneumobacillus were observed.

方法（1）鹿藿醇提取物按照国际计划生育基金会认可的杀精子实验方法，对10只小鼠附睾精子悬液和10例人精液进行体外杀精实验。

Resultsthe lowest spermicidal concentration of ethanol extract of rhynchosia volubilis lour roots on mouse and human sperm were 50mg/ml and 100mg/ml, respectively.the lowest inhibiting concentration of ethanol extract of rhynchosia volubilis lour roots on staphylococcus aureus, pseudomonas aeruginosa, escherichia coli, and pneumobacillus were 1.0,1.0,4.0,4.0 mg/ml,respectively.conclusionthe ethanol extract of rhynchosia volubilis lour roots has spermicidal and antibacterial effect.

结果鹿藿醇提取物对小鼠和人精子最低杀精浓度分别为50和100 mg/ml；对标准菌金黄色葡萄球菌、铜绿假单胞菌、大肠埃希菌、肺炎克雷伯菌mic分别为1.0，1.0，4.0，4.0 mg/ml。对临床分离菌金黄色葡萄球菌、铜绿假单胞菌、大肠埃希菌mic分别为0.5，2.0，8.0 mg/ml。结论鹿藿醇提取物对小鼠和人精子有一定杀精作用，对临床常见致病菌有比较强的抗菌作用。

Bax protein was expressed mainly in spermatogoni and primary spermatocytes, and sometimes the expression was also seen in spermatids and spermatozoa within some seminiferous tubules.
