Abstract: | Background and Methods: To elucidate the effect of hyperglycemia on disaccharidase activities, the specific and total activities of the disaccharidases were measured in the intestinal mucosa and kidney cortex of diabetic and hyperglycemic rats. The diabetes was induced with an intraperitoneal injection of streptozotocin (60 mg/kg). The rats were made hyperglycemic with an intravenous instillation of a solution containing 40% dextrose monohydrate at a rate of 1.5 ml/h for 24 h. Results: |
