[Effect of different types of excessive feeding on the state of vascular walls in rats].

Immature male rats were overfed for a long time with an excess of fats or carbohydrates; this caused obesity. Carbohydrate overfeeding led to a greater body weight gain and a greater increase in the weight of epididymal fat and of the adipose cell volume than fat overfeeding, but failed to decrease the lipolytic activity of the aorta. Prolonged fat overfeeding decreased the lipolytic activity of the aorta considerably. Thus, the results of the mentioned experiments showed that the predisposition of the aortic wall to atherogenesis did not correlate with the gain in weight and depended on the character of nutrition.
