Abstract:
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.
