RESUMO

Thoracic lymph duct cannulations were performed shortly after a meal in rabbits trained to ingest a moderate fat, low cholesterol diet. A tracer dose of cholesterol-3H was administered to label exogenous (dietary) cholesterol during absorption. Sequential lymph samples were collected up to 24 hr postprandially, after which ultracentrifugal fractionation of lymph lipoproteins was carried out. The d < 1.006 lipoproteins were separated into two classes, chylomicra and very low density lipoproteins (VLDL).
