The final step in acid secretion is believed to result from the H+-K+-ATPase-mediated exchange of H+ in the parietal cell, with K+ in the lumen. To study the K+ secretion we used Picoprazole and insulin separately and together to inhibit gastric secretion stimulated in gastric fistula dogs with histamine (100 micrograms X kg-1 X h-1). Picoprazole, a substituted benzimidazole (750 mg/kg), reduced gastric H+ concentration and volume with a rise in K+ concentration [( K+]) to 20-25 meq/l. Insulin alone inhibited acid output to the same extent as Picoprazole but with a marked fall in [K+]. Insulin (0.6 U/kg) given with Picoprazole did not alter inhibition of H+ but prevented the large decrease in gastric juice [K+]. An injection of KCl (1 meq/kg) 1 h after Picoprazole did not alter the effects of the inhibitor. Pepsin secretion after insulin was delayed by Picoprazole, whereas during bethanechol chloride infusion (80 micrograms X kg-1 X h-1) pepsin output was reduced for a shorter period and to a lesser extent than acid. We concluded that insulin affects gastric H+ and K+ secretion by a mechanism not related to H+-K+-ATPase and that Picoprazole affects pepsin secretion probably indirectly via its effect on the parietal cell, where its action is quite consistent with an effect limited to inhibition of the H+-K+-ATPase of the parietal cell.
