Chronic inflammation was induced in C57BL/6 with intraperitoneal (IP) complete Freund’s adjuvant (CFA), serial injections of subcutaneous turpentine (Turp), peritoneal catheter infection (Cath) or IP brucella antigen (Brucella). Control mice received normal saline injections. Hemoglobin was determined at the end of 3 weeks for all models except Cath at 4 weeks. Mice in the top panel were maintained on a 4 ppm iron diet during the experiment whereas in the lower panel, mice were on 20 ppm iron.
