This study is being done because we want to learn if hemin can increase the production of
heme oxygenase 1. Heme oxygenase 1 (HO-1) is an enzyme which protects cells from physical,
chemical, and biologic stress. Hemin is produced from red blood cells and is approved by the
Food and Drug Administration for treating acute porphyria, which is an inherited condition
caused by an enzyme deficiency.
