纳洛酮组第3～7天内的MCA的平均血流速度、平均全血黏稠度和红细胞变形指数皆低于对照组（P<0.05）；
The mean speed of blood flow in MCA, the mean blood viscosity and erythrocyte deformity index at 3to 7days were lower than those in the control group(P<0.05).
除此之外，一天内血液容积和粘稠度也略有变化，因此，人们不难理解，要使血压稳定在可接受的平均值，必须得用复杂的控制器。
Added to this there are slight changes throughout the day in the volume and viscosity of the blood, so one can see that complex controls are necessary to keep blood pressure at an acceptable average.
