N2 - The influence of diets supplemented with mussels, from polluted (MPoll) and non-polluted (MNPoll) areas, on some atherosclerosis indices in rats fed cholesterol (Chol) were studied. According to the results of our investigation in vitro, mussels from polluted areas had higher contents of proteins, metals and antioxidant compounds, mostly phenolics and higher antioxidant capacities. 28 male Wistar rats were divided into 4 groups of 7 and named Control, Chol, Chol/MPoll and Chol/MNPoll. The rats of the Control group received basal diet (BD) only, and the diets of the other 3 groups were supplemented with 1% of non-oxidized cholesterol (NOC), 1% of NOC and 5.6% of mussel dry matter (DM) from polluted and 1% of NOC and 5.6% of mussel DM from non-polluted areas for Chol, Chol/MPoll and Chol/MNPoll, respectively. The histology of the aorta and brain in rats fed cholesterol did not show any signs of atherosclerosis. Some differences were registered in the electrophoretic protein patterns of plasma in rats, with mussel-supplemented diets. In full plasma electrophoretic patterns of the Chol/MPoll diet group more proteins were detected than in both Chol and Control groups, and the differences were significant. In conclusion, in groups of rats fed cholesterol with mussels supplementation, a significant hindering in the rise of plasma lipid levels and also hindering in the decrease of plasma antioxidant activity were registered.
