Mean concentration–response curve for relaxations induced by ATP (0.3–30 μM) (a) and CO (50 μM–1 mM) (b) on U46619 (0.1 μM)-precontracted longitudinal muscle strips of the rat gastric fundus under NANC conditions. Relaxations were measured as peak amplitudes. Peak amplitudes are expressed as percentages of the maximal contraction induced with U46619 (0.1 μM) in each strip. Each point represents the mean±s.e.m. of responses observed in eight (a) or four (b) strips.
