Postmortem changes in resistivity of the anterior abdominal wall during the early postmortem period in rats.
An accurate and reproducible technique was employed for the determination of the resistivity of excised portions of the anterior abdominal wall of rats. Resistivity decreased linearly (r = -0.93; P < 0.001) from 1438 +/- 131 omega.cm, immediately following death, to 360 +/- 144 omega.cm at a postmortem interval of 36 h. These changes are believed to reflect the morphological and/or chemical changes which occur at the cellular level during the early postmortem period.
