Modifications by high K⁺ (addition of 15 mM K⁺) and glibenclamide (1 mM) of relaxant responses to acetylcholine in monkey lingual arteries with intact endothelium in the presence of indomethacin (1 μM) and L-NOARG (0.1 mM). The ordinate denotes relaxations relative to those induced by papaverine (0.1 mM). Numbers in parentheses indicate the number of strips from individual monkeys. Significantly different from control (C), †P<0.05 (unpaired t-test). Vertical bars represent s.e.mean.
