This study was performed to investigate the antidiabetic effect of ethanol extract of Phelladrindron Amurense Rupr (P.A) in Streptozotocin(STZ) induced diabetic rats. Diabetes was induced by intravenous injection of STZ at a dose of 45mg/kg,b.w. dissolved in citrate buffer. The ethanol extract of P. A was orally administrated once a day for 7 days at a dose of 1,000mg/kg. The content of serum glucose, was significantly decreased in P.A treated group compared to the those of STZ-control group. The content of hepatic glycogen and activities of glucokinase(GK) and glucose-6-phosphate dehydrogenase(G-6-PDH) were significantly increased(p<0.05), and activity of glucose-6-phoshatase(G-6-Pase) was significantly decreased(p<0.05) in P.A treated group compared to those of STZ-control group, These results indicated that ethanol extract of P.A have antidiabetic effect in STZ-induced diabetic rats.

This study was carried to investigate the antidiabetic effect of ethanol extract in Streptozotocin(STZ)-induced diabetic rats. Diabetes was induced by intravenous injection of STZ at a dose of 45mg/kg dissolved in citrate buffer. The ethanol extract of Forsythia Koreana(F.K) was orally administrated once a day for 7 days at a dose of 1,000mg/kg. The contents of serum glucose, triglyceride(TG), total cholesterol were significantly decreased in F.K treated group compared to the those of STZ-control group. The content of hepatic glycogen and activity of glucokinase(GK) were significantly increased, and activity of glucose-6-phoshatase(G-6-Pase) was significantly decreased in F.K treated group compared to the those of STZ-control group, but activity of glucose-6-phosphate dehydrogenase(G-6-PDH) was not significantly increased, These results indicated that ethanol extract of F.K would have antidiabetic effect in STZ-induced diabetic rats.

This study was carried to investigate the antidiabetic effect of ethanol extract of Astragali Radix(A.R) in Streptozotocin(STZ) induced diabetic rats. Diabetes was induced by intravenous injection of STZ at a dose of 45mg/kg dissolved in citrate buffer. The ethanol extract of A. R was orally administrated once a day for 7 days at a dose of 1,000mg/kg. The contents of serum glucose, triglyceride(TG), total cholesterol were significantly decreased in A.R treated group compared to the those of STZ-control group. The content of hepatic glycogen and activities of glucokinase(GK) and glucose-6-phosphate dehydrogenase(G-6-PDH) were significantly increased, and activity of glucose-6-phoshatase(G-6-Pase) was significantly decreased in A.R treated group compared to the those of STZ-control group, These results indicated that ethanol extract of A.R would have antidiabetic effect in STZ-induced diabetic rats.

This study was carried to investigate the antidiabetic and lipid metabolism of water extract paecilomyces japonica(PJ) in Streptozotocin (STZ) induced diabetic rats. Diabetes were induced by intravenous injection of STZ at a dose of 42mg/kg dissolved in citrate buffer. The water extract of paecilomyces japonica were orally administrated once a day for 7 days at a dose of 500mg/kg or 1,000mg/kg. The contents of serum glucose, triglyceride(TG), total cholesterol were significantly decreased in PJ treated group compared to the those of STZ-control group. The content of hepatic glycogen and activities of glucose-6-phosphate dehydrogenase(G-6-PDH), glucokinase(GK) were significantly increased, but activity of glucose-6-phoshatase(G-6-Pase) was significantly decreased in PJ treated group compared to the those of STZ-control group. These results indicated that water extract of paecilomyces japonica would have antidiabetic and lipid metabolism effect in STZ-induced diabetic rats.

This study was carried to investigate the antidiabetic metabolism effect of water extract $Cordyceps$ $Militalis$(C.M.) in Streptozotocin(STZ) induced diabetic rats. Diabetes were induced by intravenous injection of STZ at a dose of 42mg/kg,b.w. dissolved in citrate buffer. The water extract of C.M. was orally administrated once a day for 7 days at a dose of 500mg/kg,b.w(body weight). or 1,000mg/kg.b.w. The content serum glucose was significantly decreased in C.M. treated group compared to the those of STZ-control group. The content of hepatic glycogen and activities of glucose-6-phosphate dehydrogenase(G-6-PDH), glucokinase(GK) were significantly increased, but activity of glucose-6-phoshatase(G-6-Pase) was significantly decreased in C.M. treated group compared to the those of STZ-control group. These results indicated that water extract of C.M. would have antidiabetic metabolism effect in STZ-induced diabetic rats.

This study was carried to investigate the antidiabetic effect of ethanol extract of Smallanthus sonchifolius(S.S) in Streptozotocin(STZ)- induced diabetic rats. Diabetes was induced by intravenous injection of STZ at a dose of 43mg/kg dissolved in citrate buffer. The ethanol extract of S,S in leaves and root were orally administrated once a day for 7 days at a dose of 1,000mg/kg. The contents of serum glucose, triglyceride(TG), total cholesterol were significantly decreased in S.S treated group compared to the those of STZ-control group. The content of hepatic glycogen and activity of glucokinase(GK) were significantly increased,and activity of glucose-6-phoshatase(G-6-Pase) was significantly decreased in S.S treated group compared to the those of STZ-control group, but activity of glucose-6-phosphate dehydrogenase(G-6-PDH) was not significantly increased, These results indicated that ethanol extract of S.S would have antidiabetic effect in STZ-induced diabetic rats.
