采用核孔滤筛法测定老年和非老年各40例脑卒中病人及对照组的静脉血制备成的红细胞和红白细胞悬液的滤过指数(FI)。发现红细胞悬液FI在三组间无显著性差异,而红白细胞悬液的FI在三组间呈极显著性差异(P<0.01)。经分析作者认为,此种差异系脑卒中病人较正常人和老年脑卒中病人较非老年脑卒中病人的白细胞流变性明显降低所致。并对老年脑卒中病人白细胞流变学特性降低的意义进行了讨论。
The filtration index (FI) of erythrocyte and erythroblast suspension prepared from venous blood of 40 stroke patients and control group were measured by nuclear pore filter. FI of erythrocyte suspension was found to be no significant difference between the three groups, while FI of erythroblast suspension was significantly different between the three groups (P <0.01). The analysis of the authors believe that such differences in stroke patients than normal and elderly stroke patients than in non-elderly patients with stroke significantly reduced leukocyte rheology. The significance of reducing leukocyte rheology in elderly patients with stroke was also discussed.
