Myoelectrical and Mechanical Activity of Isolated Canine Stomach Perfused in vitro with Fluorocarbon
Bibliographic record
Abstract
Myoelectrical and mechanical activities were recorded from whole isolated canine stomachs perfused, intravascularly, with fluorocarbon emulsion, oxygenated in vitro. The perfusate was composed of an oxygen carrier, fluorcarbon, emulsified with a surfactant added to a simulated physiological solution. Bipolar electrodes and a strain gauge were used for recordings. Stomachs perfused as above for 5 h displayed normal electrical and mechanical activities. 'Normal' meaning identical with those observed under in vivo conditions or during perfusion with homologous blood. Normal response to electrical stimulation of a vagus nerve branch or to intraarterial injection of methacholine or pentagastrin were also observed. These functions of smooth muscles were not altered when glucose-free or glucose-and phosphate-free perfusate were used. In calcium-free perfusate, electrical and mechanical activities were absent and no responses to stimulants used were recorded. When calcium was added to the perfusate, these functions were restored to normal. Strontium was found to be an adequate substitute for calcium in fluorocarbon perfusate. Gastric secretions were alkaline and contained fluorocarbon emulsion.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
