【Abstract】 OBJECTIVE To investigate the effects of 3 different primitives or the same primitives with different characters of Tibetan medicine Zuomoxing[Caragana changduenais Liou f. with red heartwood, Caragana jubata(Pall.) Poir. with brown and white heartwood] on rats with pattern of toxic heat-induced blood stasis. METHODS Ninety SD rats were randomly divided into the blank group, model group, aspirin-positive group, Changdu low-dose group(CDD), Changdu high-dose group(CDG), whitewood of Guijian low-dose group(GJBD), whitewood of Guijian high-dose group(GJBG), brown wood of Guijian low-dose group(GJZD),Brown wood of Guijian high-dose group(GJZG). Models with heat toxicity and blood stasis pattern were established by intraabdominal injection of carrageenan combined with tail vein injection of lipopolysaccharide.The effects of each group on blood rheology,coagulation four indices and blood routine were determined,and the content of arachidonic acid(AA),IL-1β,IL-6,TNF-αand thromboxane B2(TXB2) were measured with ELISA.RESULTS (1)Blood rheology:Compared with model group,CDD and CDG significantly decreased whole blood viscosity(WBV),reduction viscosity of whole blood(WBRV),erythrocyte rigidity index(HGX),erythrocyte deformability index(EDI),whole blood relative index(WBRI)(P<0.01),and increased plasma viscosity(P<0.01).GJZG and GJZD significantly decreased HGX(P<0.01 or P<0.05),and increased plasma viscosity(P<0.01).GJBG and GJBG significantly decreased WBHSV,WBHSRV,HGX,EDI,and whole blood high shear relative index(WBHSRI)(P<0.01).(2)Coagulation four indices:Compared with model group,CDD significantly reduced the thrombin time(TT)(P<0.01).GJZG significantly reduced activated partial thromboplastin time(APTT) and TT(P<0.01 or P<0.05).GJBD significantly reduced prothrombin time(PT) and APTT (P<0.01 or P<0.05).(3)Blood routine:Compared with model group,GJZD and GJBD significantly decreased the percentage of monocytes(P<0.01 or P<0.05).The number of large platelets in CDD significantly increased(P<0.05).CDG significantly increased the platelet number,platelet hematocrit,and large platelet number(P<0.01 or P<0.05),and tended which to be normal.(4)Inflammatory factors:Compared with model group,the levels of TNF-α,IL-6,TXB2 were significantly increased in CDD and CDG(P<0.01 or P<0.05).The levels of IL-6 and TXB2 were significantly increased in GJZD and GJZG(P<0.01).GJBD was significantly increased TXB2(P<0.01),and GJBG was significantly increased IL-1β,IL-6,and TXB2(P<0.01),while decreased AA(P<0.05).CONCLUSION Zuomoxing with separate sources have different degrees of effects on rats with pattern of toxic heat-induced blood stasis,and have different degrees of effects on hemorheology,coagulation factors,blood routine and inflammatory mediators,and the degree and trend of effects are different with different doses.The effect of promoting blood circulation and removing blood stasis was generally manifested as Changdu>whitewood of Guijian>Brown wood of Guijian.The effect of promoting blood circulation and removing blood stasis may be the result of multiple pathways and mechanisms.更多还原
