Effect of Hovenia dulcis Thunb Extract on the Hyperglycemic Mice Induced with Streptozotocin

자구자(Hovenia dulcis Thunb) 추출물이 Streptozotocin으로 유발된 고혈당 생쥐에 미치는 영향

  • Published : 2005.06.01

Abstract

This study has been carried out to understand the effect of Hovenia dulcis on the hyperglycemic mice induced with streptozotocin (STZ). Mice in control group were administered with $0.9\%$ saline (2 mL/kg), and experimental groups were administered Hovenia dulcis extract (H1 group, 0.01 g/kg: H2 group, 0.04 g/kg) after hyperglycemic state was induced. Blood glucose concentrations of tile H1 and H2 groups administered with Hovenia dulcis extract for 6 weeks were significantly (p<0.01), compared to control group. Blood glucose tolerance was more favorable in H1 and H2 groups than control group. The Langerhan's islet of pancreas was destructed by treatment of STZ in the control group, but pancreatic islet of the experimental groups was partially recovered from damage, and a number of insulin-positive cells were observed. A number of insulin-like growth factor- I and II (IGF-I and IGF-II) positive cells occurred in the acinar cells of H1 and H2 groups. These results suggest that administration of Hovenia dulcis extract help mice recover from the damage induced with STZ.
