Abstract:
BACKGROUND: Chinese kidney-tonifying herb is commonly used in orthopedics department. However, individual effects of different ingredients remain poorly understood. OBJECTIVE: To observe influence of effective ingredients of Chinese kidney-tonifying drugs on bone healing and hemorheology of rats with bone injury. METHODS: Rat model of fracture of shaft of the femur was established, and treated by intragastric administration separately with extractive rhizoma drynariae total flavonoids, epimedium total flavonoids, dodder total flavonoids, naringin, quercetin and hesperidin. Blood and bone samples were harvested after 21 days to detect the extent of bone healing and hemorheology indexes. RESULTS AND CONCLUSION: The effective constituents of different Chinese kidney-tonifying drugs were beneficial to bone healing, and the effect of rhizoma drynariae total flavonoids and epimedium total flavonoids was better than the other drugs. Rhizoma drynariae total flavonoids and epimedium total flavonoids effectively inhibited blood viscosity under low shear, and reduced erythrocyte aggregation index and the aggregation and adhesion of platelet (P < 0.05), but it had no evident effects on erythrocyte deformation. This shows that the effective ingredient of the Chinese kidney-tonifying drugs can promote bone healing and exert certain effects on hemorheology. In particular, rhizoma drynariae total flavonoids exhibits the best effect.
