The effect of different doses of atropine on gastric myoelectrical activity in fasting experimental pigs
Bibliographic record
Abstract
Electrogastrography (EGG) is a non-invasive method for the assessment of gastric myoelectrical activity. Porcine EGG is comparable with human one. There are no data on the impact of moderate to high doses of atropine on EGG, neither in humans nor experimental pigs. The purpose of this study was to evaluate the effect of different doses of atropine on EGG in experimental pigs.Six fasting pigs entered the study three times in a random order. The baseline EGG recording lasted 20 min, followed by a 105-min EGG trial recording. Intramuscular atropine 1.5 mg (part 1), 3.0 mg (part 2) and 4.5 mg (part 3) was administrated after the baseline EGG.Atropine doses of 1.5 and 3.0 mg revealed a similar pattern in the EGG power course. After an initial increase (at the first 15-min interval), the areas of amplitudes decreased back to values comparable with basal levels and subsequently increased significantly again to the maximum at 105 min. The EGG power was quite different after the administration of 4.5 mg of atropine. Areas of amplitudes decreased gradually to the minimum values at 105 min after atropine administration.In conclusion, different dose-dependent changes in the EGG pattern were found after moderate to high doses of atropine.

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.
