目的研究银杏叶提取物（ＥＧＢ）对老龄前期小鼠血液流变学的影响。方法采用毛细管微量法和毛细管微量热沉法分别测定红细胞压积（ＨＣＴ）及纤维蛋白原（Ｆｉｂ），应用全自动血液流变仪测定全血粘度（ηｂ）、红细胞聚集系数（ＶＡＬ）、血栓形成系数（ＴＥＬ）。结果ＥＧＢ（２５，５０，１００ｍｇ·ｋｇ－１，ｉｇ，ｑｄ×２１）可明显降低老龄前期小鼠的ＨＣＴ、Ｆｉｂ，同时可降低ηｂ，缩小ＶＡＬ及ＴＥＬ。结论ＥＧＢ能明显降低老龄前期小鼠血液粘度，对其血液流变性具显著改善作用
Objective To study the effect of Ginkgo biloba extract (EGB) on hemorrheology in pre-aging mice. Methods The contents of hematocrit (ηb), erythrocyte aggregation coefficient (VAL) and thrombus were measured by capillary flow microtitration and capillary calorimetry respectively. The levels of hematocrit (HCT) and fibrinogen The formation coefficient (TEL). Results EGB (25, 50, 100 mg · kg-1, ig, qd × 21) significantly reduced HCT and Fib in pre-aging mice, and at the same time decreased ηb and decreased VAL and TEL. Conclusion EGB can significantly reduce the blood viscosity of pre-aging mice, which can significantly improve the hemorrheology
