Electroacupuncture and Brain Protection against Cerebral Ischemia: Specific Effects of Acupoints
Figure 2
EA-induced changes in CBF in the ischemic cortex varied with stimulation of different acupoints. The CBF was measured in 6 ischemic rats subjected to EA treatment at different acupoints. Blood perfusion (PU), concentration of moving blood cells (CMBC), and velocity of blood cells (Velocity) were measured by a laser Doppler perfusion monitor system. (a) Changes in CBF in response to EA at different acupoints. (b) CBF in each EA condition. (c) Statistical summary of the changes in CBF in response to EA stimuli. , MCAO versus MCAO plus EA (PU); , MCAO versus MCAO plus EA (CMBC); , MCAO versus MCAO plus EA (Velocity). Note that EA at acupoints Du 20 and Du 26 and left LI 11 and PC 6 induced isochronous increase in PU and CMBC in addition to a decrease in Velocity, but EA at right LI 11 and PC 6 acupoints and left SP 6 and GB 34 acupoints had no significant effects on CBF despite using the same EA parameters.
