| 摘 要： | 目的 为寻找一种精确推定死亡时间的方法。方法 应用 754分光光度计,在 420nm波长下,检测了 48只家兔死后不同时间的眼玻璃体液消光度,探讨其与死亡时间的关系。结果 眼玻璃体液消光度（ X）与死亡时间（ Y）呈线性正相关（ r=0.983 27, P< 0.05）,在死后 0～ 72小时,眼玻璃体液消光度与死亡时间存在回归关系（ F=116.54, P< 0.05）,直线回归方程为： Y = 453.30X＋ 0.75 Y为死亡时间 (PMI),单位为小时; X为眼玻璃体液消光度 ]。结论眼玻璃体液消光度的测定可作为推断死后 72小时内死亡时间的参考指标之一。 |

| Abstract: | OBJECTIVE: To seek a exact method of estimating Postmortem interval (PMI). METHODS: This study was preformed to investigate the relationship between postmortem interval and absorbance in vitreous humor of rabbit after death. The absorbance in vitreous humor of 48 rabbits after death were investigated with Model 754 spectrophotometer in apt wavelength (420 nm). RESULTS: There exists positive linear regression association between postmortem interval (Y) and absorbance in vitreous humor (X) (r = 0.98327, P < 0.05), during rabbits after death 0 to 72 hours. The formula of linear regression is Y = 453.30 X + 0.75 (Y = postmortem interval = PMI, X = absorbance in vitreous humor). CONCLUSION: The absorbance in vitreous humor can be as reference indicator to estimate PMI within hour 72. |
