Abstract
The corneal water is studied by NMR measurements. There are two fractions of water, one more strongly bound to relaxation centres of proteoglycanes and the other almost freely diffusible as liquid bulk water. A quantitative analysis shows that the bound fraction makes up a very small part (less than 1%) of the total water. So nearly all the water is available for the nutrition of the cornea by diffusion.
摘要
通过核磁共振测量来研究角膜中的水。水有两种成分，一种与蛋白聚糖的弛豫中心结合得更紧密，另一种几乎像液态自由水一样可自由扩散。定量分析表明，结合部分仅占总水量的很小一部分（不到1%）。因此，几乎所有的水都可通过扩散用于角膜的营养。
