[Effect of Euonymus alatus on the blood glucose and hemorheology in the rat model of Type 2 diabetes mellitus with blood stagnation].

OBJECTIVE

To explore the effect of Euonymus alatus on the blood glucose and hemorheology in rat model of Type 2 diabetes mellitus with blood stagnation (DMBS).

METHODS

High fat diet with streptozocin was used to establish the rat model of Type 2 diabetes mellitus, followed by the prednisolone and adrenaline muscle injection to obtain DMBS. DMBS rats were divided into a DMBS group (treated with saline gavage), an Euonymus alatus group (treated with Euonymus alatus gavage), and a glybenzoylamide group (treated with glybenzoylamide gavage).A blank group was treated with saline gavage. The experiment lasted 4 weeks, followed by the evaluation of rats' behavior, and detection of fasting blood glucose and hemorheology.

RESULTS

Compared with DMBS rats, the symptoms of polydipsia and diuresis in Euonymus alatus rats were improved, with increased body weight (P<0.05), better fur and mental state, increased resistance for being caught, and reduced tongue stagnation. Compared with DMBS group, though body weight increased, resistance for being caught decreased in the glybenzoylamide group with bad fur and mental state,and tongue stagnation. As to the fasting blood glucose, there was significant difference between the Euonymus alatus group and the DMBS group (P<0.05). As to the hemorheology, including whole blood viscosity (shear rates 1,5,50, and 100 s(-1)), plasma viscosity, and hematocrit, the Euonymus alatus rats had a better efficacy than DMBS rats and glybenzoylamide rats (P<0.05 or P<0.01).

CONCLUSIONS

Euonymus alatus can reduce the fasting blood glucose of DMBS and improve blood stagnation.
