[Visco-elasticity of whole blood in healthy young men and women].

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.
