Abstract

It is commonly stated that, if hemoglobin were dissolved in the blood plasma rather than enclosed in corpuscles, the viscosity of the blood would be greatly increased. We found that when the corpuscles of dog or goat blood were disrupted with ultrasound, giving a solution with the same hemoglobin concentration, the relative viscosity was drastically reduced. It appears, therefore, that the existence of blood corpuscles does not contribute to a reduced viscosity of blood.

摘要

人们通常认为，如果血红蛋白溶解在血浆中而不是包裹在血细胞中，血液的粘度会大大增加。我们发现，当用超声波破坏狗或山羊血液的血细胞，得到血红蛋白浓度相同的溶液时，相对粘度会急剧降低。因此，血细胞的存在似乎并不会导致血液粘度降低。
