【摘要】 本文利用微吸管实验方法，在研究大鼠运动力竭前后多形核中性粒细胞在缓冲盐－白蛋白溶液中的粘弹性的基础上，着重探讨了大鼠运动力竭前后ＰＭＮ在自体血浆及交叉血浆中粘弹性。结果表明，运动前大鼠ＰＭＮ在自体血浆中的粘弹性与其在缓冲液中的粘弹性没有显著差异（Ｐ＞０．０５），运动力竭后ＰＭＮ在自体血浆中粘弹性参数比其在缓冲液中的粘弹性参数明显增大（Ｐ＜０．０５）（弹性模量Ｋ２除外）；大鼠运动前ＰＭＮ在交叉血浆中的粘弹性参数比其在自体血浆中粘弹性参数明显增大（Ｐ＜０．０５），而大鼠运动力竭后ＰＭＮ在交叉血浆中的粘弹性参数比其在自体血浆中粘弹性参数明显减小（Ｐ＜０．０５）。更多还原

【Abstract】 The Viscoelastic properties of rat PMNs in media with autoplasma and crossplasma after exhausted exercise were investigated using the micopipette aspirating experiment method.The results showed that there was little diffference between buffered solution and autoplasma in terms of viscoelastic properties (P>0.05) before exercise,while there was a remarkable difference after exhausted exercise (P<0.05).Compared with those in autoplasma,the viscoelastic parameters of rat PMNs in crossplasma changed significantly(P<0.05).更多还原
