Normal reference value of whole blood viscosity (230s−1) of old women and geographical factors

In order to supply a scientific basis for uniting the normal reference value standard of hemoglobin of Chinese older boys. Methods: A research is made about the relationship between the normal reference value of 14751 examples of hemoglobin of older boys and five geographical factors in 92 areas in China, which are determined by the hemoglobincyanide method. Results: It is found that the correlation of geographical factors and the normal reference value of hemoglobin of older boys are quite significant (F = 9.68). By using the method of multiple linear regression analysis, one regression equation is inferred: Ŷ = 108.0 + 0.003633X1 + 0.003945X2 + 0.1680X3 − 0.6310X4 + 0.005518X5 ± 8.3 Conclusion: If geographical values are obtained in some areas, the normal reference value of hemoglobin of older boys of this area can be reckoned by using the regression equation. Furthermore, the depending on the geographical factors, China can be divided into six districts: Qingzang, Southwest, Northwest, Southeast, North and Northeast district.

Significant Difference

Haemorrheological factors have been shown to be affected in many kings of vascular disease. The present study was undertaken to correlate these factors in normal subjects and patients suffering from peripheral arterial disease. Twenty-two patients were investigated; they had moderate or severe intermittent claudication, extent of disease being confirmed by aorto-arteriography and ankle-systolic pressure studies. Twenty-five controls with no symptoms or signs of arterial disease were selected with comparable age and sex distribution. Whole blood viscosity was measured at shear rates of 230 secs-1 and 23 secs-lat 37°c using a Wells Brookfield cone plate microvisco meter. Plasma viscosity was also measured in an identical manner. Erythrocyte flexibility was measured by centrifuge technique and fibrinogen concentration as well as haematocrit by standard techniques. The fibrinogen concentration appeared to be the only significant parameter; the mean concentration in patients with peripheral vascular disease of 463 ± 73mg/l00ml in the control group ( < 0.05). Although whole blood viscosity was high in patients, when corrected to a common haematocrit, there was no significant difference between patients and controls. The same megative correlation was found for plasma viscosity. The red cell flexibility was found to be increased in patients as compared to the control group, but this effect appeared to be simply proportional to the fibrinogen concentration.
