document.write('Dr. Ignarro shared the Nobel Prize in 1998 for the discovery of nitric oxide (NO). In a land-mark study published in the New England Journal of Medicine in 1992, he and his co-workers showed that NO plays a major role in the mechanism through which the nerves supplying the penile artery lead to increased blood flow, engorgement of the corpora cavernosa, and erection. He has also helped to define the role of moderate exercise in enhancing nitric oxide production by blood vessels, and in rabbits on a high cholesterol diet (see below) he has shown that nitric oxide production is increased by L-arginine, L-citrulline, Vitamin C, and vitamin E, and that these supplements, markedly reduced the development of atherosclerosis. His book, NO More Heart Disease, is a fascinating account of the discovery of nitric oxide as one of the most important health-enhancing substances in the body.<br>');

document.write('The figures to the left from his study in the Proceedings of the National Academy of Sciences show blood vessels from rabbits fed a high cholesterol diet with (on the right) and without (on the left), four supplements that boost NO production. Although L-arginine may be of greater importance in the rabbit because the regular diet of these rodents does not contain as much meat and other protein sources as the regular American diet, Dr. Ignarro has included all four of these supplements as well as an antioxidant and folic acid in his recommended supplement, <a href="http://www.herbalife.com/catalog/catalog.jsp?cid=620972&pid=843688">"Niteworks"</a>, for the prevention of heart disease.</a><br><br>');
