Abstract:
:Inhalation of nitric oxide (NO) is an experimental treatment for severe pulmonary hypertension. Being rapidly metabolized by hemoglobin, inhaled NO causes selective vasodilation in the pulmonary vascular bed. In addition to the vascular smooth muscle, other pulmonary structures are exposed to inhaled NO, resulting in suppression of NO synthesis in a variety of pulmonary cells and in potential toxicity. NO is a free radical that interacts with a number of proteins, particularly metalloproteins. Together with superoxide radical, it rapidly forms highly toxic peroxynitrite. Peroxynitrite is involved in the killing of microbes by activated phagocytosing macrophages. In severe inflammation, peroxynitrite may be responsible for damaging proteins, lipids, and DNA. Peroxynitrite added to surfactant in vitro is capable of decreasing the surface activity, inducing lipid peroxidation, decreasing the function of surfactant proteins, SP-A and SP-B, and inducing protein-associated nitro-tyrosine. Exposure of animals for prolonged periods (48 to 72 hours) to inhaled NO (80 to 120 ppm) has been associated with a decrease in surface activity. This is caused by binding of surfactant to iron-proteins that are modified by NO (particularly methemoglobin), or by peroxynitrite induced damage of surfactant. In contrast, exposure of isolated surfactant complex to NO during surface cycling strikingly decreases the inactivation of surfactant, preventing the conversion of surfactant to small vesicles that are no longer surface-active, and preventing lipid peroxidation. This finding is consistent with the function of NO as a lipid-soluble chain-braking antioxidant. It is possible that this lipophilic gas has as yet undefined roles in regulation of surfactant metabolism and maintenance of surface activity. Deficiency in pulmonary NO may be present during the early neonatal period in respiratory distress syndrome and in persistent fetal circulation. The premature lung is likely to be sensitive to NO toxicity that may include lung damage, abnormal alveolarization, and mutagenicity. Defining of the indications, the dosage, and the toxicity of inhaled NO therapy remains the challenge for experimental and clinical research.
