Cytokine-SPIO Protocol Purpose: To compare the iron particles present in macrophages of apo E-deficient atherosclerotic plaques under baseline conditions (control group) and after the administration of the cytokines TNF-alpha and IL-1beta (test group). Protocol: Eight retired female breeders, approximately 12-month old were divided in 2 groups. Five received I.P. 0.2 µg each of mouse recombinant TNF- and IL-1ß; the 3 control received 0.5 mL saline

Cytokine-SPIO Protocol•Purpose: To compare the iron particles present in macrophages of apo E-deficient atherosclerotic plaques under baseline conditions (control group) and after the administration of the cytokines TNF-alpha and IL-1beta (test group).  •Protocol: Eight retired female breeders, approximately 12-month old were divided in 2 groups. Five received I.P. 0.2 µg each of mouse

recombinant TNF- and IL-1ß; the 3 control received 0.5 mL saline containing 1% BSA. Three hours later, all the animals were I.V. injected with Feridex 1 mMol/kg of iron. Seven days later, the recipients were euthanized with CO2 and perfused under physiological pressure.The entire aorta up to the iliac bifurcation was formalin-fixed, serially sectioned transversally and stained for H&E and iron.
