摘　　要：目的寻找一种精确推定PMI的方法。方法应用电感耦合等离子体质谱(ICP-MS),系统研究了家兔死后96h内眼玻璃体液21种元素含量与PMI的相关性。结果眼玻璃体液Co、Mo、Cd、Sb、I、Pb、Bi、Li共8种元素与PMI无关。K、Mg、Fe、P、Na、Al、Ca、Ti、Ni、Cu、Zn、Sr、Ba共13种元素含量与PMI有关。结论眼玻璃体液K、Mg、Fe、P、Na、Al、Ca、Ti、Ni、Cu、Zn、Sr、Ba共13种元素与PMI有关。为研究人尸体眼玻璃体液元素与PMI的关系奠定了选择指标的基础。Objective To seek a precise method for estimating postmortem interval(PMI)in forensic medicine practice.Methods This study detected the concentration of21elements in the vitreous humor of rabbit within96hours after death and explored the relationship between their concentration and PMI using the method of ICP-MS.Result It was shown that the concentration of9elements in vitreous humor of rab bit within different intervals after death were correlated to PMI available as a reference indicator to estimate PMI.Conclusion 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.
