The Effect of Aminophylline on Pentagastrin-Induced Secretion and Motor Activity of Totally Isolated Canine Stomach Perfused Extracorporeally
Bibliographic record
Abstract
Totally isolated canine stomachs, perfused extracorporeally with homologous blood of living oxygenerator-dogs, were used for the study of gastric secretion. Aminophylline and pentagastrin were infused into the gastric arterial system separately or combined. Aminophylline, infused alone, did not stimulate gastric secretion. However when aminophylline was administered during the infusion of pentagastrin, it significantly augmented the action of this peptide on gastric acid secretion. Aminophylline did not alter myoelectrical and mechanical response to pentagastrin nor did it affect the myoelectrical activity of the nonstimulated stomach. Gastric arterial perfusion pressure and gastric peripheral resistance were reduced during infusion of aminophylline alone or in combination with pentagastrin.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
