[Effect of alimentary hypercholesterolemia on the lipid composition of the chyme and of the blood flowing from the intestines].

The wall of the rabbit small intestine was found to take part in regulation of the balance of general lipids, fatty and bile acids of arterio-venous blood both in intact animals and in those with hypercholesterolemia. Excessive amount of cholesterol in food reconstructs the lipid composition of enterocytes which loose important bile and fatty acids, accumulating nonequivalent intermediary products of lipid metabolism which affects the membrane permeability, readjusts the lipid exchange in enterocytes and their control over lipid complexes circulating in the blood.
