| 摘 要： | 本实验旨在观察切除脾脏对犬心肌缺血时血液流变学变化的影响。结果表明,切除脾脏后,阻断冠脉血流120min内血细胞比容与高切变率下全血粘度升高程度明显减轻;心肌缺血40min和80min时低切变率下全血粘度升高程度减轻;但对心肌缺血120min时低切变率下全血粘度变化及血浆纤维蛋白原浓度、血浆粘度变化均无明显影响。

| Abstract: | Effects of splenectomy on changes of hemorrheologic parameters in the earlystage of myocadial ischemia were observed in dogs.The results showed thatsplenectomy alleviated he increase in hematocrit and high shear viscosity of wholeblood(r= 230 s~(-1)during 120 min of myocardial ischemia induced by coronaryocclusion.Splenectomy reduced the increase in low shear viscosity of wholeblood(r=5.75 s~(-1))at 40 min and 80 min Post-occlusion,but did not affec itat 120min post-occlusion.Splenectomp had no effect on changes in blood viscosityfibrinogen concentration and plasma viscosity following coronary occlusion. |
