Electroacupuncture and Brain Protection against Cerebral Ischemia: Specific Effects of Acupoints

Figure 1

EA-induced reduction in the infarct volume varied with stimulation of different acupoints. The brain slices were subjected to TTC staining and the ischemic infarct volume was quantified by a computerized image system. Note that the infarct region (pale-white portion) was mainly located in the striatum and the frontoparietal cortex in the right hemisphere. The slices on the right of each column show the backside of the left slices. The MCAO-induced infarction (a) was significantly reduced by EA treatment at the acupoints Du 20 and Du 26 (b) and LI 11 and PC 6 on the left anterior limb (c). In contrast, EA treatment with the same parameters at the acupoints LI 11 and PC 6 on the right anterior (d) and SP 6 and GB 34 on the left posterior limbs (e) enabled no appreciable protection against cerebral infarction.
