[Blood lipoprotein transfers in the normal arterial wall. Study auto-historadiography in optic microscopy]

In order to study the mecanisms of serum lipoproteins transfers and binding sites in arterial wall, auto-historadiographies in optical microscopy were realised with rats aortas. Animals received infusion of in vivo labelled on the cholesterol and purified serum lipoproteins. The results confirmed the serum lipoproteins transfers in arterial wall and slow that the inflow is all the more quicker and higher as the molecule is smaller. The very particular aspect of these transfers rises several hypothesis and leeds to suggest the possibility of preferential way of passage inside the arterial wall.
