Pharmacodynamic Study of Yunkang Capsule / 中药新药与临床药理

ABSTRACT

Objective To investigate the pharmacodynamic action of Yunkang Capsule(YKC).Methods The animals were divided into YKC groups(at high-,moderate-and low-dosage respectively),diphenidol control group,model control group and blank control group.The action of YKC on vertigo and thrombosis,hemorrheologic indexes,piamatral microcirculation and free radicals of the animal models were observed.Results YKC could significantly prolong the latency of vertigo,reduce wet weight of thrombus,decrease blood viscosity,plasma viscosity and hematocrit,promote the dilation of piamatral micro-vessels,increase the amount of interweave microdot,increase plasma SOD activity and decline plasma MDA content of animal models.Conclusion YKC has actions of counteracting vertigo and thrombosis,improving hemorrheology and microcirculation,and clearing away free radicals.
