[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.

Result: 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.

[Study on the relationship between PMI and the concentration of magnesium and iron in the vitreous humor of rabbit after death].

Objective: To seek a exact method of estimating postmortem interval (PMI).

Methods: This study detected the concentration of magnesium (Mg) and iron (Fe) in vitreous humor of rabbit at 96 h after death and explored the relationship between their concentration and PMI using a method ICP-MS.

Results: The concentra-tion of Mg in vitreous humor of rabbit at 48 h after death and Fe in vitreous humor of rabbit at 6-48 h after death were related to PMI significantly.
