RESUMEN
Objective To observe the effect of Yiqi Fuzhi Granule on activating blood circulation and removing blood stasis in rat models of multiple infarctional dementia.Methods Internal carotid artery injection method was used to establish rat models of multiple infarctional dementia.The changes of blood rheology,blood platelet aggregation,thromboplastin time,plasmozyme time and kaolin partial thromboplastin time before and after operation were observed.Results Yiqi Fuzhi Granule could markedly improve blood rheology in rat models of multiple infarctional dementia and reduce blood viscosity and blood platelet aggregati on rate,the effect being obvious before operation.Conclusion Yiqi Fuzhi Granule has a good action of activating blood circulation and removing blood stasis.
