OBJECTIVE:To explore the anti-inflammatory effect of Musk eye drops on acute ceratitis.METHODS:The model of acute ceratitis resulting from surgical injury was established in rabbits and which were randomly assigned to Musk eye drops groups(0.3%,0.15%,and 0.05%),0.5% Cortisone acetete eye drops group and 0.9% Normal Saline group(control).The corneal epithelium growth at 24,48h,and 72h was observed by fluorescein(2%)staining,levels of protein,Ca2+,IL-1? in the aqueous humor were determined,corneas were weighted and corneas tissues were sampled for histopathologic examination.The anti-inflammatory effect of Musk eye drops on acute ceratitis resulting from surgical injury was discussed.RESULTS:Corneal bedewing was mitigated,transmigration of neutrophilic leukocytes were inhibited,levels of protein and IL-1? in the aqueous humor were decreased,level of Ca2+ in the aqueous humor was altered and the corneal epithelium growth was promoted in Musk eye drops groups(0.3%,0.15%,and 0.05%).CONCLUSION:Musk eye drops had remarkable anti-inflammatory effect on acute ceratistis.
