Alterations in aorta histopathology and NO concentrations in the four groups. (a) Representative images of HE staining in sections of the rat aorta, magnification 400x. (b) Representative images of Verhoeff-Van Gieson staining in sections of the rat aorta, magnification 400x. The scale bar indicates 20 μm. (c) Serum NO metabolite levels after 12 weeks of treatment. N = 6. (d) NO metabolite levels in the rat aorta after 12 weeks of treatment. N = 6. (e) The aortic intima-media thickness after 12 weeks of treatment. N = 7-8. Control: healthy rats receiving normal tap water. CG: healthy rats receiving water containing 1% (w/v) glycine. DM: diabetic rats receiving normal tap water. DG: diabetic rats receiving water containing 1% (w/v) glycine. ^∗p < 0.05, ^∗∗p < 0.01 compared with the control group; ^#p < 0.05 compared with the DM group.
