This study was designed to investigate the effect and mechanism of allicin on hyperhomocysteinemia-induced experimental vascular endothelial dysfunction in rats. Fifty male Wistar rats were randomly divided into five groups: the normal control rats (NC), the high-methionine-diet rats (Met), the high-methionine-diet rats treated with folic acid, vitaminB₆ and vitaminB₁₂ (Met+F), or with low-dose allicin (Met+L), or with high-dose allicin (Met+H). After 6 weeks, we collected blood samples of all groups to determine plasma endothelin (ET), serum homocysteine (Hcy), nitric oxide (NO), superoxide dismutase (SOD), malondialdehyde (MDA), and detected the expression of basic fibroblast growth factors (bFGF), transforming growth factor beta (TGF-β), tumor necrosis factor-alpha (TNF-α), and intercellular adhesion molecule-1 (ICAM-1) in the aorta...
