摘要
经4周跑台耐力训练造成大鼠血管内溶血,在扫描电镜下观察RBC形态、测定MCD、计算MCT,分析其畸变规律。结果显示,模型组RBC畸变率达42.4%,与对照组比显著增多(P<0.01)。RBC畸变主要向正常→棘形、正常→球形两个方向发展,同时模型组MCT增大(P<0.05)。说明大鼠耐力训练所造成的血管内溶血,首先是造成了RBC畸变,正常RBC经出棘呈棘形变是其畸变的主要方向。耐力运动可能通过某种途径破坏RBC膜骨架,致RBC畸变,刚性增加,脆性增大,流变性降低,在通过毛细血管时的应力作用下易致破裂,导致血管内溶血的发生。
It is brought about intravascular hemolysis on rat after four weeks endurance training on treadmill,the shape of erthrocyte is observed under SEM,MCD is tested,MCT is calculated.The result shows that the rate of RBC aberrance increase in model group (P<0.01),meanwhile the MCT increase than control group(P<0.05).Intravascular hemolysis is caused by endurance training on rats,and leads to RBC aberrance.The direction of RBC aberrance becomes thorn like.Endurance exercise may destroy the membrane skeletal of erythrocytes,lead to RBC easily break when RBC pass to capillary and lead to intravascular hemolysis.
