摘　　要：研究大负荷跑台训练对大鼠红细胞的影响,阐明运动性低血色素大鼠血液流变学的变化。12只雄性Wistar大鼠随机分为对照组(CG)和运动性低血色素组(SG)。于运动后5周取材,用血液流变仪测定血液流变学指标,用血涂片观察红细胞形态学指标。结果显示:运动性低血色素组全血黏度和还原黏度均显著低于对照组(P<0.01),而红细胞刚性指数显著高于对照组(P<0.01)。血浆黏度两组间无明显差异。血涂片显示运动性低血色素组有较多红细胞碎片。这说明红细胞数量降低和红细胞变形能力下降是引发运动性低血色素的重要原因。The authors studied the effects of heavy load treadmill training on the erythrocytes of rats, and specified hermoreheological changes of rates with kinetic hypochrosis. The authors randomly divided 12 male Wistar rats into a control group and a kinetic hypochrosis group. After 5 weeks of training, the authors took samples, measured hermoreheological indexes of the rats by using a hermoreheological instrument, observed the morphological indexes of erythrocytes by using blood smears, and revealed the following findings： the whole blood viscosity and reduced viscosity of the rats in the kinetic hypochrosis group are all significantly lower than the same of the rats in the control group （P〈0.01）, while the erythrocyte rigidity index of the rats in the kinetic hypochrosis group is significantly higher than the same of the rats in the control group; there is no significant difference in blood plasma between the rats in the two groups; blood smears indicate that there are more erythrocyte fragments in the rats in the kinetic hy- pochrosis group. The findings indicate that the decrease of the number of erythrocytes and the deterioration of the deformation ability of erythrocytes are important causes for triggering kinetic hypochrosis.
