[Method] The crude drug solutions of four different prescriptions for Zengrujianniusan were prepared through reflux extraction. Their antibacterial activity in vitro against Staphylococcus aureus and Streptococcus agalactiae in cow mastitis were investigated. [Result] All the four different prescriptions exhibited antibacterial activity against S. aureus and S. agalactiae. Among them, prescription Ⅲ was extremely sensitive, and had the best bactericidal effect. The other three prescriptions were highly sensitive. [Conclusion] This study provides a theoretical basis for the development of herbal preparations for the treatment of cow mastitis.展开更多

The total solids, fat, protein, water soluble nitrogen （WSN）, acid value of cheese, fat, salt, titratable acidity, pH levels in Mud cheeses were variable according to whey characteristics used in their production. Wide variations were found in the total bacteria, Coliform bacteria, Staphylococcus aureus, yeast-mould, Lactobacillus spp. and Streptococcus spp. counts of cheese samples. The presence of coliforms, Staph. aureus and yeast-moulds indicate poor hygienic conditions of cheese production.展开更多

SFA gel and placebo gel were intravaginally administered. In vivo antibacterial effects,vaginal microenvironment, vaginal smears, pathological tissues of vaginas, and retention of gel in the vaginal cavity were investigated.RESULTS: SFA gel had much higher antibacterial effect than placebo gel. SFA gel protected the vaginal mucosa from erosion of bacteria. At the same time,they inhibited the inflammatory responses, exhibiting little leukocytes and parabasal cells. Furthermore, the number of vaginal Lactobacilli remarkably increased following administration of SFA gel.However, the vaginal p H did not recover to thehealthy acidic levels after treatment due to the buffering effect of gel. The gel of a fluorescent agent,Cyanine 7, showed very long retention time in the vaginal cavity, up to more than 24 h, much longer than the solutions.CONCLUSION: The SFA gel is a promising medicine for local treatment of AV with the advantages of anti-bacteria, protection of vaginal mucosa, increase of Lactobacilli, and long retention time in the vaginal cavity.展开更多
