Abstract

Aims: In humans, impaired gastric accommodation is associated with early satiety and weight loss. In animals, accommodation involves activation of gastric nitrergic neurones. Our aim was to study involvement of nitric oxide in gastric accommodation and in meal induced satiety in humans. Methods: The effect of N G -monomethyl- l -arginine (l -NMMA) 4 mg/kg/h and 8 mg/kg/h on gastric compliance, on sensitivity to distension, and on gastric accommodation was studied with a barostat in double blind, randomised, placebo controlled studies. The effect of l -NMMA 8 mg/kg/h on meal induced satiety was studied using a drinking test. Results: l -NMMA had no significant effect on fasting compliance and sensitivity. Ingestion of a meal induced a relaxation of 274 (15) ml which was significantly smaller after l -NMMA 4 mg/kg/h (132 (45) ml; p=0.03) or l -NMMA 8 mg/kg/h (82 (72) ml; p=0.03). l -NMMA 8 mg/kg/h significantly decreased the amount of food ingested at maximum satiety from 1058 (67) to 892 (73) kcal (p<0.01). Conclusion: In humans, fasting gastric tone and sensitivity to distension are not influenced by nitric oxide synthase inhibition, but the gastric accommodation reflex involves activation of nitrergic neurones. Inhibition of nitric oxide synthase impairs accommodation and enhances meal induced satiety.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
