About

Postprandial increases in the levels of atherogenic chylomicron remnant lipoprotein particles have long been considered a presumable risk factor for the development of atherosclerosis with time, also in normolipidemic subjects. apoB-48 (Chylomicron) in blood is a specific marker for intestinal derived lipoproteins. Specific aim: To determine if apoB-48 containing lipoproteins may appear in IC in the postprandial state after a standard meal and investigate the effect fasting and feeding have on levels of lipids, apolipoproteins and the cholesterol component of lipoproteins in IF and plasma.

Methodology: Intercellular fluid will be collected using the cup technique. IF will be collected in intervals corresponding to different periods after food intake. The IF from these different occasions will then be analysed and compared using FPLC and Elisa.

Enrollment: 22 patients

Sex: All

Ages: 18+ years old
