title: Regulatory effects of gastrin and secretin on carcinomas of the stomach and colon.
abstract: Gastrin (10 micrograms/ml) enhanced 14C-leucine uptake in cultured tissue of stomach and colon carcinomas and content of 14C-labelled protein in the medium was increased. One of 2 stomach and one of 3 colon carcinomas transplanted into nude mice were enhanced in growth by pentagastrin injected in a dose of 250 micrograms/kg every day. On the other hand, secretin (100 U/kg) inhibited the trophic action of pentagastrin.
