摘要 背景:作者前期将透明质酸钠和碱性成纤维细胞生长因子分别加入基础培养基,制成改良角膜保存液并证实其对角膜内皮细胞活性的保存作用。目的:探讨碱性成纤维细胞生长因子及透明质酸钠在角膜中期保存液中的作用及其有效浓度,评价该两种物质联合对角膜内皮细胞的保护作用。方法:在以基础培养基MEM、M-199为主要成分,添加6%葡聚糖、HEPES缓冲系、抗生素等制成角膜保存液的基础上,加入不同浓度的透明质酸钠和碱性成纤维细胞生长因子,并设立未加透明质酸钠及碱性成纤维细胞生长因子的对照组。各组于4℃下保存新西兰大白兔角膜片,于3,5,7,10,14d,行裂隙灯检查、锥虫蓝-茜素红染色、角膜组织病理切片及扫描电镜观察检测角膜内皮细胞活性,评价保存质量。结果与结论:加入碱性成纤维细胞生长因子及透明质酸钠的中期角膜保存液保存的角膜片其透明度、内皮细胞活性、显微结构、超微结构均明显优于未加组,各实验组同期比较,浓度较高组效果优于浓度较低组。碱性成纤维细胞生长因子及透明质酸钠同时加入基础保存液中能够对角膜内皮细胞进行有效的保护,其效果与浓度有关。 BACKGROUND:In our previous studies,corneal preservation solution was improved by adding basic fibroblast growth factor (bFGF) combined with sodium hyaluronate,which be confirmed has effect on maintain endothelial cell activity.OBJECTIVE:To explore effects of bFGF and sodium hyaluronate in corneal preservation solution and effective concentrations,in addition,to evaluate the protect effect of these two materials on corneal endothelial cells.METHODS:6% glucosan,HEPES buffer solution and antibiotics were added into MEM and M-199 to prepared corneal preservation solution,additionally,bFGF and sodium hyaluronate with different concentrations were added.Simultaneously,control group without bFGF and sodium hyaluronate was established.Cornea of New-Zealand white rabbits preserved in each group were detected by slit-lamp examination,trypan blue-alizarin red staining,and scanning electron microscope at 3,5,7,10 and 14 days after operation.RESULTS AND CONCLUSION:The transparency,endothelial cell activity,microstructure,as well as ultrastructure of the improved corneal preservation solution group were obviously better than those of the other group.Compared among the experimental groups,the high concentration group was superior to the low concentration group.The findings demonstrated that bFGF and sodium hyaluronate in corneal preservation solution can protect corneal endothelial cells,and the effectiveness is related to concentration.
