Title: Dietary ethanol-induced modifications in hyperlipoproteinemia and atherosclerosis in nonhuman primates (Macaca nemestrina).
Abstract: Male Macaca nemestrina were studied in an experiment with a 2 x 2 factorial design. Diets contained low vs high cholesterol levels (0.3 vs 1.0 mg/Kcal) and no ethanol or ethanol, as 36% of the calories substituted isocalorically for carbohydrate. After receiving their diets for 18 months, the monkeys had blood samples drawn for lipoprotein analyses, and then were killed for evaluation of the extent of atherosclerosis. Ethanol-fed groups had significantly increased concentrations of serum cholesterol, triglycerides, low density lipoprotein, and high density lipoprotein. The molecular weight of the low density lipoprotein particles was lower in ethanol-fed animals and the cholesterol esters of low density lipoprotein and high density lipoprotein contained relatively more cholesteryl linoleate and less cholesteryl oleate. Dietary cholesterol had the effect of increasing the concentration of low density lipoprotein (primarily via increasing the low density lipoprotein molecular weight) and decreasing the conc...
