Study finds carbon monoxide has therapeutic benefits

January 20, 2003

Exposing rats to low levels of carbon monoxide (CO) prior to aorta transplantation prevents arteriosclerosis associated with chronic organ rejection and can also suppress stenosis after balloon-angioplasty-induced carotid artery injury, according to a study published in the Feb. 1 edition of Nature Medicine. The article is published online today.
"These findings demonstrate a significant protective role for CO in vascular injury and support its use as a therapeutic agent," according to study author Leo Otterbein, Ph.D., research assistant professor, University of Pittsburgh School of Medicine, division of pulmonary and critical care medicine.
