Dietary mucilage promotes regression of atheromatous lesions in hypercholesterolemic rabbits.
The antihypercholesterolemic and antiatherogenic effect of the mucilage galactomannan isolated from fenugreek seeds was studied in experimental rabbits maintained on a high cholesterol diet for 3 months. Changes in the levels of cholesterol and triglycerides in serum and tissues and aortic fatty lesions were analysed in animals receiving mucilage (40 mg/kg body weight) daily and compared with the control. A significant decrease in serum total cholesterol, LDL cholesterol and triglycerides and cholesterol and triglycerides in liver and aorta and a decrease in Sudan IV staining of aorta indicated antihypercholesterolemic and antiatherogenic effects of the mucilage. Regression studies showed that administration of mucilage for 3 months caused a significant decrease in serum total and LDL cholesterol and aortic cholesterol. Mucilage accelerated the regression of atheromatous lesions in the aorta as evidenced by significantly low sudanophilic staining. Recovery from inflammation in hypercholesterolemic animals receiving mucilage was evidenced by a faster decrease in C-reactive protein (CRP) in serum to basal levels. The lipid lowering and antiatherogenic effects of mucilage from fenugreek which is used as a food flavoring spice highlights the importance of dietary intervention in the regression of atherosclerosis.
