Freezable and non-freezable water content of cataractous human lenses.

摘要: Twenty-nine cataractous human lenses between the ages of 36 and 93 were investigated. The total water content cortex nucleus obtained by vacuum dehydration. freezable was measured differential scanning calorimetry. non-freezable difference. To measure extent that syneresis contributes to cataract formation, an excess function designed. represents changes occur, for example, in due cataractogenesis. It is calculated as difference a normal lens same age. On average, there 7% less than lens. corresponding number 9%. This 29 36% changes, respectively, during
