Changes to I _sc and G _t induced by serosal trypsin. a Time-course characteristics for the changes in I _sc and G _t induced by 1 nM–100 μM trypsin added to the serosal side at the arrowed time (n = 4–8). Mean values are presented. b Concentration dependence of the serosal trypsin-induced increase in I _sc (ΔI _sc) and G _t (ΔG _t). Values were obtained when the peak I _sc increases were reached. Each data value is presented the mean ± SE, the number of animals used being 4–8
