[Compensatory and adaptive changes in the small intestine and liver of rabbits after short-term cholesterol diet]

Functional and morphological changes in the intestinal wall and liver were studied in rabbits on short-term cholesterol diet. It was established that with a rapid increase of cholesterol concentration in the general blood flow, the synthesis of high density lipoproteins in the intestinal wall was intensified. Enhanced hepatic elimination of cholesterol and chylomicrons from blood circulation contributes to cholesterol level stabilization in peripheral blood. With high density lipoprotein accumulation in the intestinal wall, cholesterol consumption did not change its concentration in the general blood flow. Structural changes in jejunal and liver mucosa were shown to depend on the degree of hypercholesterolemia and functional damage of these organs.
