Methods The blood stagnant syndrome model was reproduced by injecting dextran 500 into the marginal ear vein. The BCM and the hemorrheology properties were detected and compared. Results Compared with the normal group, the model groups indexes of whole blood relative and whole blood reducing viscosity improved (P 0.01 ～0.05), erythrocyte sedimentation rate (ESR) became quicker, erythrocyte sedimentation rate K (ESRK) increased, erythrocyte aggregation index and erythrocyte transmutation index increased, BCMs morphological mark and total mark increased (P 0.01).
