检测NS（21例）、AGN（11例）患儿不同病期血液流变学指标结果表明，NS组急性期低中高切变率WBV、ηP和RAI明显增高，缓解期ηP恢复正常，但WBV、RAI仍高于正常；AGN组仅急性期呈低切变率WBV、ηP和RAI增高。提示NS和AGN在不同病期存在不同特点的血液流变性异常。其发生机制主要与红细胞聚集性增高和血浆粘度增加有关。 The results of hemorheological indexes at different stages of NS (21 cases) and AGN (11 cases) showed that the low, middle and high shear rates of WB, AP and RAI in acute NS group were significantly increased and ηP returned to normal in remission stage, but WBV , RAI is still higher than normal; AGN group showed low shear rate WBV, ηP and RAI only in acute phase. Tip NS and AGN at different stages of the existence of different characteristics of the abnormal blood rheology. Its mechanism mainly associated with increased erythrocyte aggregation and plasma viscosity.
