Aim To research therapeutical effect of marine lysozyme suppository on bacterial vaginitis caused by S. aureus and E. coll. Methods Lysozyme obtained from concha ostreae which were used to preparate marine lyso- zyme suppository. The identification and test of suppository was in line with the standards stated in Chinese pharma- coperia（2010 edition）. After determined its quality control, we studied its therapeutical effect on bacterial vaginitis which caused by S. aureus and E. coli, by vaginitis model in rats infection of S. aureus bacteria and E. coli. Results The preparation technology of marine lysozyme suppository was simple, convenient and clinically effective. The marine lysozyme suppository was delivered by dose 0.5, 0.25, 0. 125 g ~ kg-1, the cure rates of S. aureus infec- tion were 80% , 50% and 30% , respectively, the cure rates of E. coli infection were 90% , 60% and 30% re- spectively, the cure rates of mixed infection were 92.9% , 82. 1% and 92.9% respectively. Marine lysozyme sup- pository had an outstanding therapeutical effect on bacterial vaginitis which caused by S. aureus and E. coll. Con- clusion The preparative process of marine lysozyme suppository was practicable, and it had a good therapeutic effect on bacterial vaginitis caused by S. aureus and E. coll.
