Objectives : The aim of this study was to investigate the effect of Jaeumyangyung-tang(滋陰養榮場(JY), JA-0.65g/kg;JB-1.3g/kg) on hyperglycemic mice induced with streptozotocin(STZ). Methods : The experiment operated for 6 weeks. The rats were divided into 3 groups : diabetic group(control group), diabetic group treated with JA(0.65g/kg) for 6 weeks, and diabetic group treated with Jb(1.3g/kg) for 6 weeks. Results : In the STZ-induced diabetic group, blood glucose levels significantly increased as well as the loss of body weight. The levels of serum glucose decreased significantly (p<0.05 or p<0.01) in the JA and JB groups compared with the control. According to a tolerance test, intraperitoneal glucose was ameliorated in the JA and JB groups. The blood urea nitrogen (BUN) and creatinine levels slightly decreased. Histologic analyses of the pancreases revealed that the ${\beta}-cells$ on Langerhans' islets were destroyed by STZ, but the ${\beta}-cell$ mass was larger in the JY than in the control mice. Conclusions : These results indicate that JY can exert beneficial effects on diabetes. preservation of in vivo ${\beta}-cell$ function and regeneration of ${\beta}-cell$ dysfunction by STZ.
