Control: healthy rats receiving normal tap water. CG: healthy rats receiving tap water with 1% glycine added. DM: diabetic rats receiving normal tap water. DG: diabetic rats receiving tap water with 1% glycine added. N = 7-8. ^∗p < 0.05, ^∗∗∗p < 0.001 compared with the control group. ^###p < 0.001 compared with the DM group.
