该文观察了频率为20 Hz,振幅为0 .2cm , 加速度为1 .1g 的振动对轻度失血性休克大鼠血液流变学特性变化的影响。将20 只健康雄性 Wistar 大鼠随机分成两组, 每组10 只。实验组:振动10d(30min ×2 次/d) 。抽动脉血3ml造成轻度失血,24h 后继续振动10d(20min ×2 次/d) 。对照组:不加振动, 其他处理相同。结果发现 实验组大鼠振动第一阶段 血浆比粘度明显低于对照组( P< 0 .05) 。第二个阶段实验组大鼠的全血比粘度( 高切80s - 1 , 低切20s - 1) , 全血还原比粘度(80s- 1 ,20s- 1) ,以及红细胞刚性系数较对照组显著降低( P< 0 .01 ~0 .05) 。对照组第二阶段与第一阶段相比, 全血比粘度和全血还原比粘度以及红细胞刚性系数显著升高( P〈0 .01) 。实验组第二阶段与第一阶段相比,各项指标均无显著性差异。实验结果表明该文所取的特定参数的全身振动对轻度失血性休克大鼠血液粘度的升高有明显的改善作用。

Twenty healthy male Wistar rats were randomly divided into two groups of 10 rats. Experimental group: vibration 10d (30min × 2 times / d). Twitching blood 3ml caused mild blood loss, vibration 24h after 10d (20min × 2 times / d). Control group: without vibration, other treatment the same. The results showed that the first phase plasma viscosity of experimental rats was significantly lower than that of the control group (P <0.05). In the second phase, the whole blood viscosity (80s-1, 20s-1) and the specific viscosity of whole blood (80s-1, 20s-1) and the erythrocyte rigidity of the experimental group were significantly higher than those of the control group Decreased (P <0 .01 ~ 0 .05). Compared with the first phase in the second phase of the control group, whole blood viscosity and whole blood reduction viscosity and erythrocyte rigidity increased significantly (P <0.01). The second phase of the experimental group compared with the first phase, the indicators were not significantly different. The experimental results show that the systemic vibration of the specific parameters taken in this paper can significantly improve the blood viscosity of mild hemorrhagic shock rats.
