心脑舒通胶囊对高血压患者脑血管流速的影响

目的观察心脑疏通胶囊对高血压患者脑血管流速的影响。方法将106例高血压病患者随机分为治疗组和对照组,治疗前及治疗后均行经颅多普勒血流检查(TCD),测量脑动脉的血流速度。对照组服用氨氯地平或厄贝沙坦;治疗组在对照组治疗的基础上加心脑疏通胶囊治疗。结果治疗组治疗后脑动脉血流速度较治疗前明显改善(P<0.05或P<0.01),与对照组治疗后比较差异有统计学意义(P<0.05或P<0.01)。结论心脑疏通胶囊可改善高血压患者脑血管流速,且无不良反应。

经颅多普勒检查老年冠心病患者的临床意义

目的 探讨老年冠心病患者经颅多普勒 (TCD)检查的临床意义。方法 将 5 0例冠心病患者与对照组 4 6例无慢性疾病患者 ,分别经过TCD检测方法检测脑动脉血流流速。结果 冠心病患者各脑动脉狭窄发生比对照组多 ,有显著性差异 (P <0 0 1)。

Effect of thinking on intracranial blood flow velocities

Objective To determine the effect of thinking on intracranial blood flow velocities.Methods Transcranial Doppler(TCD)was used to measure the blood flow velocities of the cerebral arteries,when 10 normal persons were at rest and during thinking.Results The mean flow velocities(MFVs)of the cerebral arteries during thinking were significantly higher than those at rest,especially in the MCA and ACA.The MFVs were raised from between 10.3% to 14.3%.Conclusions Thinking can increase the blood flow velocities of cerebral arteries significantly.
