脑组织与法医学死亡时间推断

Estimation of postmortem interval by brain tissue

目前,通过脑组织推断死亡时间已经成为法医学领域研究的新热点,大量研究资料表明:死亡时间与脑组织细胞DNA、RNA、ATP含量及脑温度、脑组织血管内皮生长因子等变化有高度相关性。脑CT、MR I、磁共振波谱等检查手段对死亡时间的推断也有帮助。本文对国内外相关文献进行综述,以期为相关研究提供参考。

Recently, estimation of postmortem interval （PMI） by brain tissue has been a new top subject in the forensic research and practice fields. A lot of research results show that the changes of brain cell DNA content, RNA content, ATP content , brain temperature, brain vascular endothelial growth factor （VEGF） exist a high linear correlation with PMI. And brain CT, brain MRI and brain MR spectroscopy detection also play a vital role in estimating PMI. The paper reviewed recent progress of study on them.
