title: Plasma lipoproteins, postheparin plasma lipoprotein lipase activity intralipid half-life, triglyceride secretion rate and liver lipids in the mouse fed different cholesterol diets.
abstract: Mice (SC), fed a semipurified diet containing cholesterol, cholic acid and sucrose, exhibited, in comparison to control animals (S), an increase in cholesterol, phospholipid and protein of VLDL, LDL1 and LDL2, but triglyceride of the same lipoproteins decreased, as did total plasma triglycerides. Postheparin plasma lipoprotein lipase activity of SC animals was 1.72 times that of S mice. At the same time Intralipid half-life in SC mice was decreased by 52%. Triglyceride secretion rate, after Triton WR 1339 treatment, and liver triglyceride content were reduced in SC animals. HDL mass was decreased in SC mice. Mice (AC) fed a standard diet containing cholesterol showed, in comparison to normal fed animals (A), an increase in cholesterol of VLDL, LDL1 and LDL2 but triglyceride of the same lipoproteins decreased as did total plasma triglycerides. Postheparin plasma lipoprotein lipase activity of AC animals was unmodified as was Intralipid half-life. In AC animals triglyceride secretion rate, after Triton WR 1339 treatment, was reduced but in a less extent than in SC mice. Liver triglyceride was unmodified. HDL mass was decreased in AC mice.
