Effect of laser acupuncture at GV20 on brain infarct volume. (A) Representative sections of triphenyltetrazolium-chloride-stained brains from animals in each treatment group. Dark staining is indicative of viable tissue, and the absence of stain is indicative of an infarcted region. (B) Effect of laser acupuncture at GV20 on brain infarct volume in cerebral ischemic rats. Values given are the mean ± standard error of the mean (N = 5). *p < 0.05 when compared to the control. †p < 0.05 when compared to the Rt.MCAO-alone group. ‡p < 0.05 when compared to Rt.MCAO-plus-sham-laser-acupuncture group. Rt.MCAO = right middle cerebral artery occlusion.
