	Nitric Oxide Reviews: 2003
		Inducible nitric oxide synthase is induced by T helper I cytokines (interleukin-1, tumor necrosis factor and gamma-interferon), while arginases are induced by T helper II cytokines and other immune regulators such as interleukins 4, 10, and 13, transforming growth factor-beta and prostaglandin E2.
		Nitric oxide disrupts free radical and oxidant-mediated reactions, due to a strong attraction and interaction with superoxide.The level of oxidative stress is positively related to the severity of the ischaemic injury, making the results in different myocardial syndromes more concordant.
		We propose that nitric oxide is an important metabolite in hypoxic plant cells and that at least one of the functions of hypoxic stress-induced haemoglobins is to modulate nitric oxide levels in the cell.

	Nitric oxide - Wikipedia, the free encyclopedia
		The endothelium (inner lining) of blood vessels use nitric oxide to signal the surrounding smooth muscle to relax, thus dilating the artery and increasing blood flow.
		This underlies the action of nitroglycerin, amyl nitrate and other nitrate derivatives in the treatment of heart disease: The compounds are converted to nitric oxide (by a process that is not completely understood), which in turn dilates the coronary artery (blood vessels around the heart), thereby increasing its blood supply.
		Nitric oxide was named "Molecule of the Year" in 1992 by the journal Science, a Nitric Oxide Society was founded, and a scientific journal devoted entirely to nitric oxide was created.

	Nitric oxide and Impotence : by Ray Sahelian, M.D.
		Nitric oxide has a number of actions that lead to relaxation of blood vessels, regeneration of the endothelium (the inner lining of arteries), and inhibition of platelet clumping which makes the blood thinner.
		Nitric oxide is released from nerve endings and endothelial cells and stimulates the activity of guanylate cyclase, leading to an increase in cyclic guanosine-3',5'-monophosphate (cGMP) and, finally, to cavernous smooth muscle relaxation.
		Nitric oxide is also generated constitutively in neuronal cells and serves as a neurotransmitter and neuromodulator in non-adrenergic, non-cholinergic nerve endings.

	EnRhythm Benefits - Nutritional Supplement Effectiveness
		Nitric oxide is a scavenger of free radicals as well as signals a cascading of biochemical events which regulate free radicals throughout the body.
		When nitric oxide is present the digestive track is relaxed, healing takes place, and the natural movement of the colon returns to cleanse and detoxify the body, resulting in better absorption of nutrients and enhanced digestion.
		This is partly due to the fact that the increased nitric oxide signals the release of enkelytin, a naturally occurring peptide which stimulates immune cells and a natural sense of well-being.

	Spiraling high blood pressure linked to nitric oxide deficiency
		The study, conducted on rats by Dr. Nick Vaziri, professor of medicine and chief of nephrology, and his colleagues, found that nitric oxide, which helps control blood pressure by dilating blood vessels, is inactivated by increasing blood pressure.
		The researchers concluded that pressure was regulating the amount of free radicals in the body, which inactivated nitric oxide and created the cycle of pressure, leading to cardiovascular and kidney diseases.
		They now are working on a number of experiments to better define the relationships between blood pressure, nitric oxide and the risk of disease in the kidney, heart and brain.
