Short communication: Hypolipidemic and antiinflammatory effects of fermented Maillard reaction products by Lactobacillus fermentum H9 in an animal model

초록

This study examined the effects of Maillard reaction products reacted by casein and lactose (cMRP) and of cMRP fermented by Lactobacillus fermentum H9 (FcMRP) on hypolipidemic and antiinflammatory effects in rats fed a high-fat and high-cholesterol diet (HD). The HD-fed rats had significantly increased hepatic triglyceride concentrations compared with the rats fed a normal diet. It was shown that treatment with simvastatin, L. fermentum H9 (119), cMRP, and F-cMRP decreased total triglycerides in the liver compared with the HD group. On histological analysis, a reduction of lipid accumulation in the liver and aortic tissues was observed in the cMRP, F-cMRP, and 119-fed rats. Also, F-cMRP and cMRP reduced intima-media thickness in the HD group. In addition, the 119, cMRP, and F-cMRP treatments significantly reduced the expression levels of ICAM-1 and VCAM-1, but not of MCP-1. In particular, the expressions of ICAM-1 and VCAM-1 were significantly decreased in the F-cMRP group compared with the HD group. These results of the present study suggest that cMRP and F-cMRP in dairy foods could potentially be used to prevent or treat cardiovascular diseases, especially atherosclerosis.
