[Abstract]
Objective To study the influence of diosmin which is one active component abstracted from Galium verum on blood rheology of rat model and investigate the mechanism. Methods Apply epinephrin sc injection and ice water bath to make rat model of blood stasis syndrome. Rats were administered with diosmin (45, 90, and 180 mg/kg) and aspirin as a positive drug. Then make a study that how diosmin ameliorated the hemorheology by assaying the indexes of blood rheology and tetrachoric including whole blood viscosity, plasma viscosity, hematocrit, erythrocyte sedimentation rate and erythrocyte aggregation index using hemeorheology instrument and automatic ESR analyzer. Meantime, we made an approach to the subject that the influence of diosmin on the relationship between blood stasis and inflammation by assaying CRP, TNF-α, and IL-1β. Results Diosmin can improve the indexes of hemorheology obviously. It also can reduce the content of inflammatory factors. Conclution Diosmin can improve the abnormality of hemorheology, and further, it processes the properties of curing inflammation of vein and improving microcirculation by reducing the discharge of inflammatory factors effectively.
