摘要
20只家兔角膜分为正常、异体穿透性角膜移植术后2周、1、2、3个月各4只,共5组,用扫描电镜观察、拍摄伤口部位内皮细胞并利用电子计算机图象分析系统测得细胞面积、周长、密度、形状系数、最大长径,面积变异系数等形态计量学指标。结果显示:术后早期内皮细胞的形态和密度与术前有明显差异;随着术后时间的推移,其形态和密度又向正常恢复,但进程缓慢;直到术后3个月仍有部分形态学指标与正常存在差异。
The endothelium of 20 cases of rabbit cornea including the normal and postoperated ones (2 weeks and I, 2, 3 months after penetrating keratoplasty) were observed by scanning electron microscope. The photographs of the endothelium in graft-host junction were analysed by computer-assisted image analysis system and the morphometric indexes are as follows: area of the cells, perimeters, density, figure coefficient, long axis, coefficient of variation of the area, and others. After operation the morphology and the density of the endothelial cells were different from the normal ones obviously, but the cells changed from enlargement and irregularity to normal progressively. At the time when the corneas were operated for 3 months, some differences still existed.
