[Study on the relationship between PMI and the concentration of 21 elements in vitreous humor of rabbit after death].
OBJECTIVE
To seek a precise method for estimating postmortem interval (PMI) in forensic medicine practice.


METHODS
This study detected the concentration of 21 elements in the vitreous humor of rabbit within 96 hours after death and explored the relationship between their concentration and PMI using the method of ICP-MS.


RESULTS
It was shown that the concentration of 9 elements in vitreous humor of rabbit within different intervals after death were correlated to PMI available as a reference indicator to estimate PMI.


CONCLUSIONS
The changes in the concentration of certain elements in vitreous humor of vitreous humor are correlated with PMI and determination of such changes can be used to estimate the time of death.
