摘　　要：目的:为角膜移植材料的选择提供参考。方法:观察了４１只胎儿角膜和１８只成人角膜的组织结构,并对其中５５例进行了体视学测量。结果:６个月胎儿角膜就厚于成人,主要是角膜基质随胎龄增加增厚明显。角膜基质细胞数面密度随胎龄增长而逐月下降,成人值最小。角膜切片中角膜全长内皮细胞数随胎龄逐月增长,但成人其值却低于６月以后的胎儿。以上结果经方差分析,Ｐ＜０．０００１。结论:作角膜移植术时,应选用至少８个月以上胎儿的角膜。Objective: To provide reference for the choice of materials of the comeal transplantation. Method: Histological observation of cornea was studied on 41 fetus and 18 adult cadaveric specimens and stereological measurement were performed on 55 of them. Results: Corneas of over six-month-fetus were thicker than those of adult' s. The density of corneal stroma fibroblasts decreased following the increasing of fetal months, and the numerical value of adult was least.The endothelium of the horizontal diameter length in cornea section increased with the increasing of fetal months, but those of adult were less than over six-month fetus. Conclusion: The results indicate that we must choose the corneas of over eight-month fetus as materials of cornea! transplantation.
