The quantitative changes in mucopolysaccharides (MPS) and water contents in post-mortem rabbit corneas were studied. On the basis of the results, the post-mortem periods were classified into 4 stages. The first stage was during the first day after death when the MPS and the corneal water contents were observed to have maintained their initial values and the cornea was "clear". The second was 1 to 3 days after death when the MPS remained at approximately their initial value, whereas the water contents were very pronounced. In this second stage the cornea was "a little clear" or "cloudy". The third was 3 to 6 days after death when the MPS were found to have decreased gradually, but the water contents maintained their high level. The cornea in this third stage was "cloudy" or "very cloudy". The fourth was 6 or more days after death when the two parameters were found to have decreased significantly, and the cornea was "very cloudy".
研究了死后兔角膜中黏多糖（MPS）和水分含量的定量变化。根据研究结果，将死后时期分为4个阶段。第一阶段是在死亡后的第一天，此时观察到MPS和角膜水分含量保持其初始值，角膜“透明”。第二阶段是在死亡后1至3天，此时MPS大致保持其初始值，而水分含量显著增加。在第二阶段，角膜“有点透明”或“浑浊”。第三阶段是在死亡后3至6天，此时发现MPS逐渐减少，但水分含量保持在较高水平。在第三阶段，角膜“浑浊”或“非常浑浊”。第四阶段是在死亡后6天或更长时间，此时发现这两个参数均显著下降，角膜“非常浑浊”。
