Abstract

Atherosclerosis is a major cause of coronary heart disease. As a result of the development of atherosclerotic lesions, the walls of blood vessels become thicker and inhibit blood circulation. Atherosclerosis is caused by a high-fat diet and vascular injury. Chronic arterial inflammation plays an important role in the pathogenesis of atherosclerosis. In particular, secretion of the pro-atherogenic cytokine tumor necrosis factor-α induces expression of endothelial adhesion molecules including P-selectin, vascular cell adhesion molecule 1 (VCAM-1), and intercellular adhesion molecule 1 (ICAM-1), which mediate attachment of circulating monocytes and lymphocytes. In this study, we examined the anti-atherosclerotic effect of sorghum, which is known to have anti-oxidant and anti-inflammatory activity. A 50% ethanol extract of Sorghum bicolor L. Moench fermented with Aspergillus oryzae NK (fSBE) was used for experiments. In vitro expression of endothelial adhesion molecules VCAM-1 and ICAM-1 and pro-inflammatory factor cyclooxygenase-2 was significantly decreased and that of the anti-atherogenic factor heme oxygenase-1 significantly increased by fSBE (P < 0.05). At the in vivo level, we examined fat droplets of liver tissue, and aortic thickness via histological analysis, and determined the blood lipid profile through chemical analysis. fSBE at a dose of 200 mg/kg significantly improved blood and vascular health (P < 0.05). Taken together, these results demonstrate that fSBE has potential as a therapeutic anti-atherosclerotic agent.
