Abstract/OtherAbstract:

1. A method is described for measuring arteriovenous differences across the rat stomach in vivo. 2. Notable results were the uptake of branched-chain amino acids, the uptake of arginine, which was approximately balanced by an output of ornithine, and the output of alanine. 3. The fractional extraction of glutamine from the blood by the stomach wall of pentagastrin-stimulated rats was 4.7%. 4. The arteriovenous differences for ammonia depended upon the blood ammonia concentration. 5. Arteriovenous differences were not affected by the stimulation of acid secretion with pentagastrin. 6. It is concluded that the high activity of branched-chain-amino-acid aminotransferase (EC 2.6.1.42) in the gastric mucosa is associated with metabolism of these amino acids, but that the stomach wall is a less avid user of glutamine than is the small intestine. |
