The measurement of visco-elastic properties of blood of the Chinese is very important for theoretical research and clinical practice. This paper reports the study of the visco-elastic properties, rheological parameters and several biochemical components of the whole blood in 146 healthy young students. No significant difference in the concentrations of globulin, cholesterol, fibrinogen and blood sugar between the male group and female group could be found. The level of albumin, hemoglobin and triglyceride in the male group was significantly higher than that in the female group. The rheological measurement demonstrated that plasma viscosities in both the male and female groups had no significant differences and that the values of HCT, apparent viscosities at high (51.2 s-1) and low (0.512 s-1) shear rates and AI in the male group had higher values of ESR and OD than the female group. The visco-elastic parameters of whole blood, including eta', eta", G' and lambda, were higher in the male group than the female group. The physiological meaning of these differences between the groups is also discussed in the paper.

D001799 Blood Sedimentation Measurement of rate of settling of ERYTHROCYTES in blood. Erythrocyte Sedimentation,Erythrocyte Sedimentation Rate,Erythrocyte Sedimentation Rates,Rate, Erythrocyte Sedimentation,Rates, Erythrocyte Sedimentation,Sedimentation Rate, Erythrocyte,Sedimentation Rates, Erythrocyte,Sedimentation, Blood,Sedimentation, Erythrocyte
D001809 Blood Viscosity The internal resistance of the BLOOD to shear forces. The in vitro measure of whole blood viscosity is of limited clinical utility because it bears little relationship to the actual viscosity within the circulation, but an increase in the viscosity of circulating blood can contribute to morbidity in patients suffering from disorders such as SICKLE CELL ANEMIA and POLYCYTHEMIA. Blood Viscosities,Viscosities, Blood,Viscosity, Blood
D004548 Elasticity Resistance and recovery from distortion of shape.
D004903 Erythrocyte Aggregation The formation of clumps of RED BLOOD CELLS under low or non-flow conditions, resulting from the attraction forces between the red blood cells. The cells adhere to each other in rouleaux aggregates. Slight mechanical force, such as occurs in the circulation, is enough to disperse these aggregates. Stronger or weaker than normal aggregation may result from a variety of effects in the ERYTHROCYTE MEMBRANE or in BLOOD PLASMA. The degree of aggregation is affected by ERYTHROCYTE DEFORMABILITY, erythrocyte membrane sialylation, masking of negative surface charge by plasma proteins, etc. BLOOD VISCOSITY and the ERYTHROCYTE SEDIMENTATION RATE are affected by the amount of erythrocyte aggregation and are parameters used to measure the aggregation.

D005260 Female Females
D006400 Hematocrit The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.
