TABLE 1
Effect of l-NAME (10 μM) and l-arginine (l-Arg; 300 μM) in RbCC relaxations induced by ACh (0.6 nmol), metaproterenol (MET; 100 nmol), isoproterenol (ISO; 100 nmol), ritodrine (RIT; 100 nmol), fenoterol (FEN; 100 nmol), and TA 2005 (TA; 100 nmol) RbCC relaxations induced by MET, ISO, RIT, FEN, and TA were expressed (mean ± S.E.; n = 9) relative to the submaximal relaxation induced by glyceryl trinitrate, which was taken as 100%.
