Effects of increasing concentrations of UK-14,304 on cholinergic contractile activity of longitudinal smooth muscle evoked by transmural electrical stimulation of ileal (a) or colonic (b) preparations obtained from rats either in the absence or in the presence of DNBS-induced colitis. Each point represents the mean of seven to eight experiments ±s.e.m. (vertical bars). Significant difference from the respective values obtained in vehicle-treated animals: ^*P<0.05; significant difference from the respective control values: ^aP<0.05.
