摘要： 目的探讨家兔死后玻璃体液电导率变化与死亡时间的相关性。方法采用电导分析法检测家兔30℃下死后48h内及20℃下死后120h内玻璃体液电导率变化。结果30℃和20℃下家兔死后玻璃体液电导率随死亡时间延长而持续升高。经统计分析得到抛物线型二项式回归方程,其相关系数分别为0.970和0.983,两式P<0.01。结论家兔死后玻璃体液电导率升高程度可以作为推断死亡时间的参考指标。

Abstract: Objective To investigate the correlation between postmortem interval (PMI) and the changes of electrical conductivity in vitreous humor in rabbits after death. Methods The changes of electrical conductivity in vitreous humor in rabbits were measured using the conductivity meter under 30 ℃ during 0-48 hours and 20 ℃ during 0-120 hours after death. Results Electrical conductivity in vitreous humor in rabbits increased gradually under 30 ℃ and 20 ℃ from 0 to 48 hours and from 0-120 hours after death. The formulae of the relationship between PMI and conductivity under 30 ℃ and 20 ℃ were obtained by statistical analysis and the correlation coefficients were 0.970 and 0.983 (both P<0.01), respectively. Conclusion The increase of electrical conductivity in vitreous humor in rabbits after death may be used as the relatively objective parameter for PMI estimation.
