【摘要】 本文对反复献血者１２７例、高血压病８７例、缺血性中风６０例进行了血液流变学对照性研究。结果表明：高血压和缺血性中风病人的全血比粘度（高切、低切）、血浆比粘度、还原比粘度均有不同程度的增高，以女性为著。献血者的血粘度降低，以男性为著；献血者的动脉压在同等血粘度水平低于正常对照组和高血压病人组。血粘度的变动时献血者动脉压的影响小于正常对照组和病人组。结合心脏电生理指标和眼底动脉硬化程度进行分析研究，认为长则血液稀释状态，对心脑血管系统有良好的远期影响，对减少心脑血管病的发病率具有积极的预防意义。更多还原

【Abstract】 In this article,the blood rheology of 127 cases with repeated blood donors,87 cases with hypertension and 60 cases with ischemic stroke were investigated.The data showed that the whole blood ratio visCosity(high shear ratio,low shear ratio),plasma ratio viscosity ,reduced ratio viscosity in patients with hypertension and ischemic stroke increased in varying degree:,the female;were obvious.The donors’ blood viscosity decreabed,the males were obvious。The mean arterial pressure(MAP)in the male and female donors were lower than that of the normal adults and hypertensives at the same blood viscosity level.The influencing of changing in blood viscosity on the MAP in blood donors was less than that in he normal aduIts and patient groups。The data of cardic electrophysiology and funduscopy showed no significant change in the donors,due to the effect of heniodilution state。It is sug-gested that long peried of repeated blood withdraw can preduce a hemedilution state,which has well influencing in cardio and cerebro vascular system;So it may has important effect for the prevention of cardic and cerebral vascular disease。更多还原
