山茱萸总甙滴眼液防治角膜移植免疫排斥反应的实验研究

Effect of cornus officinalis glycosides ophthalmic solution on the corneal allograft rejection

目的 :观察山茱萸总甙 (COG)滴眼液局部应用对角膜移植免疫排斥反应的影响。方法 :建立封闭群大鼠角膜移植模型 ,用裂隙灯显微镜记录及比较各组角膜排斥反应发生时间 ;并进行病理学和扫描电镜检查。结果 :病理学检查B、C组 15d时的角膜植片淋巴细胞浸润及新生血管明显少于A组。免疫组化显示 :ICAM - 1的表达在 15d时B、C组明显少于A组。结论 :COG滴眼液能有效地防治角膜移植免疫排斥反应。

AIM: To observe the effect of cornus of ficinalis glycosides(COG) ophthalmic solution on the corneal allograft rejection by topical instillation. METHODS: The corneal transplantation model on the closed colony rats was established. The rejection time of all animals was recorded and compared by slit-lamp microscope. The pathologic changes were measured by immunohistochemistry and scanning electron microscope.RESULTS: The histopathological and immunohistochemistry findings showed that the lymphocytes, neovascularity and the expression of ICAM-1 in COG-treated group were significantly fewer than that in control group at 15 d after operation.CONCLUSION: COG ophthalmic solution prevents and suppresses the corneal allograft rejection.
