The effects of combined administration of tetragastrin and the ornithine decarboxylase inhibitor 1,3-diaminopropane (DAP) on the incidence and number of gastric cancers induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), and the BUdR labelling indices of the fundic and antral mucosae, were investigated in inbred Wistar rats. Rats were given drinking water containing 2.5 g/l of DAP ad libitum and received alternate-day injections of 1 mg/kg body weight of tetragastrin in depot form after 25 weeks of oral treatment with MNNG. At week 52, prolonged administration of tetragastrin alone resulted in a significant reduction in the incidence and number of gastric cancers and a significant increase or decrease in the labelling indices of the fundic and antral mucosae, respectively. Concomitant administration of tetragastrin and DAP had no effect on the inhibition by tetragastrin of gastric carcinogenesis. With this treatment, the labelling index was significantly reduced in the fundic mucosa but not in the antral mucosa. These results suggest that ODC inhibitor does not attenuate tetragastrin inhibition of gastric carcinogenesis, and that anti-trophic action of tetragastrin on antral mucosa may be related to tetragastrin inhibition of gastric carcinogenesis.
