title: Raman study of the lenses of spontaneously-occurring and streptozotocin-induced diabetic rats.
abstract: The WBN/Kob rat is an animal model of spontaneously occurring diabetes only in males at the age of around one year. The diabetic cataract develops about a half year after the onset of diabetes. Using laser Raman spectroscopy we monitored WBN/Kob rat lenses which had chronic hyperglycemic stress and streptozotocin-induced diabetic rat lenses which showed relatively acute cataract formation. WBN/Kob rat lenses revealed a marked increase in the lens water content only in the cortical portion. On the other hand, streptozotocin-induced diabetic rat lenses showed a pronounced increase in the lens water content both in the cortical and the nuclear portion.
