Lymph chylomicron composition and size are modified by level of intestinally infused cholesterol and triglyceride source in rats
Article Abstract:
Studies were made on the effects of continuous intestinal infusion of graded cholesterol amounts on the composition and size of rat intestinal lymph chylomicrons. Results show that at least 20 milligrams of cholesterol per gram of triglyceride (TG) proportionately raised chylomicron cholesterol. Cholesterol at 100 milligrams per gram of TG raised chylomicron cholesterol 5-10% by weight. Corn oil produced mostly esterified cholesterol without changing the phospholipid (PL) to TG ratio. Olive and butter oils raised unesterified cholesterol 10-30% and the PL to TG ratio.Butter oil produced the smallest chylomicrons.

Administration modalities and intestinal lymph absorption of arachidonic acid in rats
Article Abstract:
Arachidonic acid (AA) is an essential polyunsaturated fatty acid which is involved in prostaglandin and leukotriene biosynthesis. Its absorption in the intestine and incorporation into specific lymph lipid classes as well as lymph lipoprrotein formation were studied in rats. Results identified a pathway for intestinal absorption of lymph which was found to be stimulated by the presence of monoglycerides. In addition, the incorporation of AA into lymph phospholipids was shown to be determined by infused emulsion fatty acid and the presence of saturated fatty acids.

Energy expenditure in rats maintained with intravenous or intragastric infusion of total parenteral nutrition solutions containing medium- or long-chain triglyceride emulsions
Article Abstract:
A study was done on the energy expenditure in rats maintained with intravenous or intragastric infusion of total parenteral nutrition solutions containing medium- or long-chain triglyceride emulsions. Results show a greater energy expenditure with intravenous medium-chain triglyceride (MCT) infusion than with long-chain triglyceride infusion. Energy expenditure is also affected by site of infusion as reflected by the higher values obtained from intravenous infusion of MCT compared to intragastric infusion.
