    Abstract:
    Male Wistar rats were fed an atherogenic diet for four months to investigate possible diet-induced lipid alterations and brain Ca2+ ATPase activity. Total cholesterol and triglyceride levels were found to be increased significantly in both serum and brain while the phospholipid level was decreased in both. The distribution of serum cholesterol between high-density and low-density lipoproteins was altered when compared to control rats with a decrement in HDL-cholesterol and a pronounced increment in LDL-cholesterol. The atherogenic diet resulted in about 50% depression in brain Ca2+ ATPase activity. It is concluded that alterations in ion transport and neurotransmitter release may be expected due to pronounced inhibition of brain Ca2+ ATPase activity in rats fed an atherogenic diet.
