Effects of acupuncture on elastin content. Elastin was stained blue by Orcein stain. The WKY control had a higher proportion of elastin but the total content of it in their aorta tissues was lower. Acupuncture and sham-acupuncture showed no effect on both elastin fraction and elastin content. Data were expressed as means ± SD (*P < 0.001 for the WKY control vs. all other groups)
