摘要: 运用玻璃体液中钾离子的浓度升高来精确地推断死亡时间,国内外很多学者已通过各种试验建立大量的相关公式。主要以死亡时间(PMI)为自变量,钾离子浓度为因变量的直线相关和回归方程。本文作者综述近年来的相关公式及其影响因素,包括尸体例数、死亡原因、左右眼取材、玻璃体液中尿素和肌苷水平、环境温度、取材技术、检测方法和分析方法等,以尽可能精确地推断死亡时间。

关键词: 玻璃体液, 钾离子浓度, 死亡时间, 回归方程, 影响因素

Abstract: In this paper we reviewed the formulae and analyzed the factors which modified the relationship and esti-mate the time of death as precise as possible by potassium concentration in vitreous humor.The extra factors including numbers of the cases,cause of death,different eye of both,the urea or/and creatinine in vitreous humor,environmental temperature,sampling techniques,experimental and analytical method were also mentioned.

Key words: vitreous humor, potassium post-mortem interval, linear regression, extra factors
