本文结果表明经一次大剂量全身照射后的机体血液流变的主要特性为全血表观粘度先高粘后低粘的双向性变化,从照后第一天起即升高。随着放射病病程的发展,在早期有一个高粘峰,其峰均值比照前升高47.80％。但因不同动物、不同剂量、不同均速,不同血源而变化不同。 The results show that after a large dose of whole body irradiation, the main characteristics of the body blood rheology for the first two days after the first apparent increase in apparent viscosity of whole blood viscosity of the two-way low viscous changes. With the development of the course of radiation sickness, there is a high viscosity peak at an early stage, with a peak mean increase of 47.80% as compared with that before the irradiation. But because of different animals, different doses, different speed, different blood sources and different changes.
