Effect of inhaled NG-nitro-L-arginine methyl ester on Candida-induced acute lung injury.
STUDY OBJECTIVES Nitric oxide (NO) and peroxynitrite play a crucial role in acute lung injury (ALI). Whether NO synthase (NOS) inhibition is beneficial in the treatment of lung injury remains controversial. The objective of this study was to test the hypothesis that local inhibition of NOS in the lung reduces lung injury. DESIGN We developed a model of Candida-induced ALI in the mouse by IV i...
متن کاملThe role of nitric oxide synthase in endotoxin-induced uveitis: effects of NG-nitro L-arginine.
PURPOSE To evaluate the role of nitric oxide synthase (NOS) in endotoxin-induced uveitis (EIU). METHODS EIU was caused in Lewis rats by injecting lipopolysaccharide (LPS) into the foot pad, and the effects of an NOS inhibitor, NG-nitro L-arginine (NA), was comparatively studied by the simultaneous administration of NA and LPS. Total NOS and inducible NOS (iNOS) activities were differentially ...
متن کاملEndothelial modulation of contractions caused by oxyhemoglobin and NG-nitro-L-arginine in isolated dog and monkey cerebral arteries.
BACKGROUND AND PURPOSE Oxyhemoglobin is a key substance in provoking cerebral vasospasm and a scavenger of nitric oxide. The present study was designed to determine whether suppression of the action of endothelium-derived nitric oxide is involved in oxyhemoglobin-induced cerebroarterial contraction. METHODS Dog and monkey cerebral artery strips with and without endothelium were immersed for i...
متن کاملNG-nitro L-arginine methyl ester and other alkyl esters of arginine are muscarinic receptor antagonists.
Analogues of L-arginine with modifications at the terminal guanidino nitrogen and/or the carboxyl terminus of the molecule have been widely used for their ability to inhibit the production of nitric oxide and are thought to be competitive antagonists of nitric oxide synthase. The present studies were designed to test the possibility that these agents are also muscarinic receptor antagonists. Ac...
متن کاملSustained hypertension induced by orally administered nitro-L-arginine.
To study the hemodynamic and metabolic effects of chronic inhibition of endothelium-derived nitric oxide, we treated conscious rats with an oral solution of N omega-nitro-L-arginine (LNA), an inhibitor of nitric oxide production by endothelial cells. After 3 days of treatment with 2.74 mM LNA, rats had higher blood pressures (136 +/- 5 versus 113 +/- 3 mm Hg, p < 0.0005) than did the control an...
