title: Anti-diabetic effect of Wen-pi-tang-Hab-Wu-ling-san extract in streptozotocin-induced diabetic rats.
abstract: OBJECTIVE
  Wen-pi-tang-Hab-Wu-ling-san (WHW) is an oriental herbal prescription formulated using 14 herbs and has been used to cure chronic renal failure in Korean oriental medicine. In this study, we investigated the anti-diabetic effect of WHW in the streptozotocin-induced diabetic rats.
  
  
  METHODS
  Diabetes was induced by streptozotocin (STZ, 60 mg/kg, i.p.) in rats. WHW extract (100 mg/kg) was orally dosed once a day for four weeks. The results were compared with standard antidiabetic drug, glibenclamide (3 mg/kg, p.o).
  
  
  RESULTS
  Significant decrease in body weight and insulin levels and increase in blood glucose, triglycerides, urea nitrogen (BUN), and creatinine were detected in STZ-induced diabetic rats with disruption and disappearance of pancreatic and kidney cells and decrease in insulin producing beta cells. However, these diabetic changes were significantly inhibited by treatment with WHW extract. In the oral glucose tolerance test, the extract produced a significant decrease in glycemia 60 minutes after the glucose pulse.
  
  
  CONCLUSIONS
  Based on these results, we suggest that WHW extract has favorable effects in protecting the STZ-induced hyperglycemia, renal damage, and beta-cell damage in rats.
