[Effect of various fat products on the bile makeup and blood level of cholesterol].

In test conducted on rats kept for 60 days on a complete standard ration that included one of the fat varieties (sunflower, cotton oils, butter, mutton fat, margarine) a hypocholesterolemic effect of the diet with sunflower oil was recorded, which was attended by an increased excretion of bile acids and cholesterol in the bile. With the rats fed on a low-protein or fat-rich rations that included sunflower oil (30 and 60 per cent, respectively) a marked change in the ratio between the bile acids and cholesterol, in favour of the latter, was noted.
