Using electromagnetic flowmeter and Laser Coppler Microcirculatory flowmeter

we studied the effect of electrical acupuncture at Zusanli (ST 36) and Quchi (LI 11) on cerebral blood flow and pial microcirculatory blood flow in dogs. The results showed that the cerebral blood flow increased remarkably

while the cerebral vascular resistance (CUR) decreased 1 min. after the acupuncture start and 20

30

60

90 min. after stopping of the stimulation

and the blood flow of the pial microvessels increased 1

5

10 min. after starting of acupuncture and 30 min. after stopping of the stimulation. It indicates that one of the mechanisms of treatment of cerebral vascular diseases with acupuncture is that acupuncture increases the cerebral blood flow and improve the pial microcirculation.
