چکیده انگلیسی
The role of splenic ellipsoids in the trapping of particulate material and immune complexes was investigated in mink (Mustela vison). The ellipsoids were prominent, with typical features such as a permeable endothelium and a discontinuous basement membrane surrounded by a sheath of macrophages and reticular cells. Ellipsoidal trapping of circulating particles was demonstrated 10Â min after intracardiac injection of colloidal carbon and fluorescent microspheres. Preformed peroxidase-antiperoxidase immune complexes were detected in ellipsoids 10Â min and also 1Â h after intracardiac injection. Erythrocytes were frequently observed in the ellipsoidal sheath, and many phagocytized fragments of erythrocytes were found in the ellipsoidal macrophages. It was concluded that mink ellipsoids are effective blood filters with a role in retention of circulating particulate material, and that mammalian splenic ellipsoids also have the ability to trap immune complexes.
