Abstract:
OBJECTIVE:To seek a exact method of estimating postmortem interval (PMI).
METHODS:This study detected the concentration of zincum(Zn) and nickel(Ni) in vitreous humor of rabbit at hour 96 after death and explored the relationship between their concentration and PMI using a method ICP-MS.
RESULTS:The concentration of Zn and Ni in vitreous humor of rabbit at hour 24 after death were related to PMI significantly; The formulae of the relationship between PMI and Zn concentrations is y = 0.1404x2 - 1.3351x + 3.8298 (within 24 h; R2 = 0.9202). The formula of the relationship between PMI and Ni concentrations is y = 0.0043x2 - 0.0596x + 0.2665(within 24 h; R2 = 0.9103).
CONCLUSION:The concentration of Zn and Ni in vitreous humor of rabbit may be a reference indicator to estimate early PMI.
