RT Journal Article SR Electronic T1 The promise and reality of nitric oxide in the diagnosis and treatment of lung disease JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 486 OP 493 VO 68 IS 6 A1 Dweik, Raed A. YR 2001 UL http://www.ccjm.org/content/68/6/486.abstract AB Endogenously produced nitric oxide plays a major role in lung physiology and pathology.

Several issues need to be addressed, however, before it can be used in routine clinical practice.
