Trapping of Calibrated Microspheres in Rat Lymph Nodes

Abstract

The diagnostic and therapeutic usefulness of intralymphatic microspheres depends on the site and duration of lodgement of the injected particles within the lymph nodes.
The size of the spheres is probably the most important factor that determines where
and for how long the particles will remain trapped. This study was carried out to test, under controlled conditions, the filter capacity of lymph nodes for spheres of various calibers.
