Concentration of K~+ and Mg~(2+) in vitreous humor taken by alternative micro-sampling method from both eyes of rabbits for the estimation of postmortem interval / 中国法医学杂志

ABSTRACT

72h), the average deviations are over 15 hours. The average deviations of Equation 2 are almost all above 10 hours. The average deviations of Equation 3 are the lowest of the three.Conclusion The [K~+] and [Mg~(2+)] in the vitreous humor rises while the PMI extends. There are correlations between the concentration of K~+ and Mg~(2+) in the vitreous humor and the PMI. For the estimation of PMI, we suggest that the equation with R2 lower than 0.98, or with high average deviations should not be used. It seems that multiple regression equation could increase the accuracy of PMI estimation.
