Cerebral blood flow changes during and after indirect moxibustion stimulation at the acupuncture point HO-KU (L-14), which is located between the thumb and index finger, were measured by transcranial Doppler ultrasound (TCD) . The mean blood flow velocities (Vm) of the right middle cerebral artery (MCA) in 10 normal subjects were measured continuously during and until 15 minutes after the stimulation. The Vm showed 2 peaks, at 1 minute after and 7 minutes after the stimulation. The extent of change in flow velocity was 23% at the first elevation and 20 - 26% at the second elevation. The second elevation of the flow velocity continued until 15 minutes after the stimulation. The heart rate increased at the first elevation and then returned to its previous level, but did not change at the second elevation. To evaluate vascular reactivity, a hyperventilation test was done before and after the examination ; it showed normal vascular reactivity at both points. The second elevation seemed to be induced by the effect of moxibustion. Vascular reactivity remained normal and no significant vascular diameter changes seemed to occur. From our results, a significant increase of cerebral blood flow is induced by indirect moxibustion stimulation.
