Electroacupuncture and Brain Protection against Cerebral Ischemia: Specific Effects of Acupoints
Figure 4
Statistical data on cerebral blood flow (PU) in ischemic cortex in MCAO/reperfusion rats with/without EA at different acupoints. PU was measured and compared between the groups. , MCAO + EA versus MCAO; , reperfusion versus MCAO; , reperfusion in MCAO + EA group versus reperfusion in MCAO group. Note that in the Ischemia group, MCAO (0 min) decreased PU to ~15% of the base level before MCAO (−5 min). After the onset of reperfusion, PU increased slightly to ~25%. In the group of EA at Du 20 and Du 26, EA increased PU to ~32% of base level before MCAO. In the group of EA at left LI 11 and PC 6, EA also increased PU to ~29% of base level before MCAO. After the onset of reperfusion, PU in the groups of EA at Du 20 and Du 26 and left LI 11 and PC 6 almost immediately returned to >90% of the pre-MCAO level. However, EA at right LI 11 and PC 6 and left SP 6 and GB 34 did not significantly improve the CBF during MCAO and after reperfusion.
