Luminal gastrin does not activate rat stomach histidine decarboxylase. 1981

J Hedenbro, and M Ekelund, and R Håkanson, and G Liedberg, and S Vallgren

Fasted rats have a low gastric histidine decarboxylase activity. I.v. infusion of heptadecapeptide gastrin for 2 h raised the enzyme activity. Intragastric perfusion with the same dose of gastrin and for the same period of time did not reproduce the effect of circulating gastrin. It is concluded that luminal gastrin, in contrast to circulating gastrin, does not activate rat stomach histidine decarboxylase.
