ABSTRACT

Background: Qin Bing eye drop is prepared with cortex fraxini and borneol. It has been commonly used to relieve the symptoms of photokeratoconjunctivitis (PKC), chronic conjunctivitis and keratitis for more than forty years. However, the origins of cortex fraxini are various, which may result in the unstable quality. Methods: The animal model of PKC was established using rabbit’s eyes exposure to Ultraviolet (UV); levofloxaxin drop, normal saline, Qin Bing eye drops made of herbs from Hebei province and Shanxi province were respectively instilled to both eyes of rabbits; the symptoms of rabbits’ eyes were observed at different time points and scores based on weights were recorded; the recovery rates of different groups were evaluated. Results: The scores of both eyes for all rabbits were above 9 points, indicating animal models for PKC were successful; the average recovery rates of therapeutic groups, including Qin Bing eye drop groups, were higher than untreated group at different time points; the slopes of recovery rate in Qin Bing eye drop (Hebei) were above Shanxi. Conclusion: PKD animal model can be established successfully; Qin Bing eye drop groups promoted the symptoms of PKD recovering quicker than untreated group. Furthermore, Qin Bing eye drop made of herbs from province Hebei had better effects than Shanxi, which was consistent with chemical results. This indicated that chemical constituents of herbs were able to reflect the effects to a certain extent.
