Effects of Panax Notoginseng Saponins Enteric-coated Pellets on Hemorheology in Rabbits / 中国药师

ABSTRACT

Objective:To discuss the effects of panax notoginseng saponins (PNS) enteric-coated pellets on hemorrheology in rabbits.Methods:The rabbits were divided into the normal control group,the model control group,Xueshuangtong injection (lyophilization) group(15 mg·kg-1·d-1 ,im),PNS enteric-coated pellets groups respectively at high(45 mg·kg-1·d-1,ig),medium(30 mg·kg-1·d-1,ig) and low (15 mg·kg-1·d-1,ig) dose.The model was established by intragastric administration of high-fat diet.The whole-blood viscosity,plasma viscosity,erythrocyte aggregational index,crythrocyte index of rigidity and erythrocyte electro-phoresis rate in the groups were detected using hemorheological methods.Results:The above indices of hemorheology in the model control group were all significantly higher than those in the normal control group (P0.05).Compared with Xueshuangtong injection (lyophilization) group,PNS enteric-coated pellets group at medium dose could significantly reduce the whole blood middle shear viscosity(P<0.05).Conclusion:PNS enteric-coated pellets can reduce the whole-blood viscosity,plasma viscosity,erythrocyte aggregational index,crythrocyte index of rigidity and erythrocyte electro-phoresis rate,and effectively promote blood circulation and remove stasis,inhibit thrombosis formation and increase blood supply for heart and cerebral vessels.
