Abstract:
Pseudomonas aeruginosa was inoculated into corneal stroma of rabbits and the model of keratoconjunc tivitis was established. Empty liposomes were used in a control, group ofloxacin liposome and ofloxacin eyedrop groups as experimental ones. After treatment for six times conjunctival and corneal lesions were examinated. Swabs of conjunctival sac were cultured. Result: in conjunctiva, lesions in the two experimental groups were all significantly less than those in the control group on the 6th, 8th and 11th day. Lesions in the ofloxacin liposomes group were also significantly less than those in the ofloxacin eyedrop group on the6th day. In cornea, lesions in the ofloxacin liposomes group were significantly less than those in the control group on the 6 th, 8th and 11th day. Lesions in the ofloxacin eyedrop group were significantly less than those the control group on the 11th day. In the result of bacterium culture, the culture's positive rate of two experimental gronqs and control group had significant differences on the 6th day. On the 11th day, the positive rate the ofloxacin liposome groups and ofloxacin eyedrop groups increased, and in the ofloxaein liposomes group had a less increase. Conclusion: ofloxacin liposomes and ofloxacin eyedrops were effective in treatments of pseudomonas keratoconjuntivitis in the rabbit model, the effects of ofloxacin liposomes were better than that of ofloxacin eyedrops.
