[Measurement of transmucosal potential difference before and after gastric mucosal injury in dogs].
Three mongrel dogs (12-14 kg BW) were used to measure the transmucosal gastric potential difference (PD) after gastric injury by electric thermocautery under endoscopic control. The parameters obtained after mathematical fitting of the experimental data to the inverse Batemen function reflected the characteristics, surface and depth of the mucosa injury. These results suggest that a calculated gastric response (GR) is appropriate to evaluate the intensity of gastric mucosal injury.
