摘　　要：目的　研究健康老年人米餐后脑血流速度及血压、心率变化规律。方法　测定 30例健康老人[平均年龄 (70± 3)岁 ]米餐前后脑血流速度 (CFV)、血压及心率变化指标。结果　米餐后脑血流速度较米餐前显著减慢 (P <0 0 1) ,动脉血压略有下降 ,心率略快 (P >0 0 5 )。结论　米餐 30min后老年人脑血管收缩期和部分脑血管舒张期血流量减少 ,心率及血压无明显变化。Objective To study the change of cerebral blood flow velocity,atery blood pressure and heart rate after eating rice in healthy elders.Methods To inspect the cerebral blood flow velocity(CFV),brachial artery blood pressure and heart rate in 30 healthy elders aged 70±3 years at 30 minutes after eating.Results CFV of the cerebral middle artery was slower than before meal(P<0.01 ),but BP and heart rate had no significant change after meal.Conclusion The blood flow volume of cerebral partial blood vessels in the elders at 30 minutes after eating significanty decreases,but blood pressure and heart rate don't change.
