✦ Synopsis

Flame photometric determination of sodium and potassium concentrations in postmortem rat plasma In = 40) revealed the existence of a linear and inverse relationship, of high correlation (r = -0.986; P < O.OOl), between the logarithm of the plasma sodium/potassium concentration ratio (P,,/P,) and the logarithm of postmortem interval (PMI) during the 6-96-h postmortem period. This relationship, which has not been reported previously in the forensic literature, offers a simple and potentially valuable means of estimating the PM1 in man.
