Abstract

We evaluated the anti-diabetic effects of Triticum aestivum sprout water extract (TA) in diabetes mellitus type 2. For the experiments, the diabetic animal model db/db mice were divided to 3 groups: diabetic control (db/db) and two experimental groups orally treated with 25 and 100 mg/kg single dose of TA (TA-25 and TA-100, respectively). The lean mice were used as the non-diabetic normal control. All mice have free access to water and AIN-93 diet. TA was administrated to diabetic mice for 5 weeks and the diabetic clinical markers, including blood glucose level, body weight, food intake and insulin level, were measured at a time. After administration for 5 weeks, the blood glucose level was decreased 1.10 and 1.98 folds in TA-25 and TA-100 groups, respectively, compared with db/db group. The body weight and diet consumption were significantly reduced by TA treatment in dose-dependent manner. The treatments of TA-100 also significantly decreased remarkedly liver weight and slightly serum insulin levels when compared with them of the diabetic control group. However the immunohistochemical staining for insulin clearly showed high expression of insulin in the pancreatic islet cells derived from all db/db mice, even if TA was administrated. Moreover, TA-100 treatment significantly improved impaired glucose tolerance in diabetic db/db mice. The results suggest that TA has anti-hyperglycemic effect attenuating blood glucose in the animal model of type 2 diabetes and might be useful as a functional diet for human diabetic diseases.
