title: Postmortem changes in electrical resistance of the gastric wall during the early postmortem period in rats.
abstract: A simple and reliable technique was employed for measurement of (dc) electrical resistance of the gastric wall of rats. Tissue resistance decreased linearly (r = -0.87; P less than 0.001) from 66.1 +/- 12.1 kOhm/cm2 immediately following death to 23.3 +/- 3.5 kOhm/cm2 at a postmortem interval of 24 h. These changes are believed to reflect progressive postmortem changes in the physical dimensions of the intercellular space and/or changes in electrical conductivity of the intercellular/extracellular fluids.
