title: [Functional and structural changes in the small intestine during experimental hypercholesteremia].
abstract: Functional and structural changes that occurred in the small intestine and liver of rabbits with alimentary hypercholesterolemia have been studied. Maximal rise of peripheral blood cholesterol after a single exposure to cholesterol was coupled with an increased penetration of chylomicrons and low and very low density lipoproteins from the intestine to the circulation. The decrease of cholesterol excretion along the whole length of the small intestine was accompanied by activation of the release of high density lipoproteins into the blood outflowing from the intestine. The decay of chylomicrons in the liver was restricted during the first days of hypercholesterolemia. Cholesterol concentration in the bile was decreased. The microvessels of the small intestine demonstrated the dilatation of the postcapillary-venular component erythrocyte aggregates and capillarostases.
