【摘要】 将健康短毛家兔４６只随机分为２组，第１组为地榆组，２４只；第２组为空白对照组，２２只。将第１组家兔灌服地榆药液，剂量为２０ｍｌ／ｋｇ，连续两天早晚各１次；第２组灌服等量的生理盐水。第３天早晨８时从家兔心脏取血约３０ｍｌ，经抗凝后进行全血粘度、血浆粘度、血细胞压积的测定。结果表明，地榆组的全血粘度、血细胞压积与空白对照组相比均有明显增大（Ｐ＜０．０１）。提示：地榆使血液中红细胞百分比含量增高，造成集轴现象中外周血浆层厚度减少，导致全血粘度升高，从而起到止血之功效。更多还原

【Abstract】 Forty six healthy short hair rabbits were divided into two groups at random.There were 24 rabbits in the first group and 22 rabbits in the second group.The rabbits in the first group were poured with 20ml/kg of Radix sanguisorbae liquid once in the morning and once in the evening and equal volume of saline was poured in the second group at the same time in two days. About 30ml blood was drawn from each rabbit at 8:00 in the third day.The whole blood viscosity,plasma viscosity and hematocrit were measured by the capilary viscometer and et al.The result showed that the whole blood viscosity and hematocrit of the Radix sanguisorbae group,i.e.the first group were obviously higher than those of the blank control group,i.e.the second group (P<0.01). It is point out that Radix sanguisorbae can raise the blood plasma percentage in blood which lead to the movement of hemocytes to the axis,reduce the outside thickness of blood plasma layer and raise whloe blood viscosity,thus hemostyptic effect is acheived.更多还原
