Metabolism of D-[3-3H]glucose, D-[5-3H]glucose, D-[U-14C]glucose, D-[1-14C]glucose and D-[6-14C]glucose in pancreatic islets in an animal model of type-2 diabetes.

This study aims at exploring specific aspects of D-glucose metabolism, so far not yet investigated, in pancreatic islets from adult control rats and animals (STZ rats) injected with streptozotocin during the neonatal period. The latter animals, which represent a current model of type-2 diabetes, displayed a lower body weight, higher plasma D-glucose concentration and lower insulinogenic index than control rats. The protein, DNA and insulin content were all also lower in islets prepared from STZ, rather than control rats.
