Objectives:This study has been carried out to understand the effect of Cimicifugae Rhizoma and Seungmagalgeuntang on the hyperglycemic mice induced with Streptozotocin(STZ).
Methods:The 60mg/kg of STZ was fed into mice twice by 24 h interval and then 120mg/kg STZ was fed again 3 days after the earlier feeding, Control group was administered mice with 0.9% saline(2mL/kg/day), and experimental groups were administered Cimicifugae Rhizoma extract(CA group, 10mg/kg/day; CB group, 30mg/kg/day) or Seungmagalgeuntang(SA group, 10mg/kg/day; SB group, 30mg/kg/day) after hyperglycemic induction for 6 weeks.
Results:The body weight of experimental groups higher than control. The blood glucose concentration of the control group increased continuously reaching to 298.9 mg/dL after 6 weeks, however, significantly(p<0.01 or p<0.05) decreased in the SA and SB groups compared with control group. Blood insulin level significantly(p<0.01) increased in the experimental groups. The activities of SOD and catalase were more decreased in the experimental group than control group compared with normal group. In the point of pancreatic immunohistochemical change, the experimental group’s pancreatic islets have increased and enlarged and the concentration of insulin-positive beta cells has also increased, comparing with the control group. Meanwhile forms of nucleus and mitochondria in the experimental group’s hepatic cells were almost similar to the normal group.
Conclusion: The result from the six weeks of observation demonstrates that the extracts from Cimicifugae Rhizoma and Seungmagalgeuntang have positive effects on lowering blood sugar level and elevating insulin concentration. The extract had also effects on recovering and regenerating pancreatic tissue of the hyperglycemic mice induced with STZ. At the same time, it had a protective effect against hepatotoxicity as well.
