Objectives: The aim of this study was to investigate whether 1) variation of bowel sounds recorded stably through an electronic stethoscope in a sound insulation box can be related with that of gastric contraction and 2) if they are thus useful tool in the measurement of the gastric contractility in awake rats or not. Methods: Electrical potentials of both electronic stethoscope of bowel sound and force transducer were recorded simultaneously and continuously in the sound insulation box for the starting 30 min of basal state, and then 30 min of 0.2 ml normal saline administration, finally 30 min of 0.2 ml mosapride citrate solution (100 mg/Kg) in rats. Each motility index of normal saline or mosapride citrate treatment was presented with ratio against the basal state by using integrated electrical potentials. Results: A pattern of significance of gastric contractility between bowel sound and force transducer was showed analogously. Conclusions: The amplitude of bowel sounds recorded by the electronic stethoscope related with the intensity of gastric contractions. This confirms that a sound insulation box and electronic stethoscope are useful tools in the measurement of the gastric contractility of awake rats.
