The hippocampus is one of the areas most vulnerable to histopathological changes, and such changes may yield useful information in forensic medicine. We found that glial fibrillary acidic protein (GFAP)-positive astrocytes are frequently found in the hippocampus of consecutive series of forensic brains, distributed predominantly in the hippocampal CA4 and hippocampal sulcus (HS) regions. The present study counted GFAP-positive astrocytes in these regions and investigated associations with age, cause of death and postmortem time. Significant correlations were found between age and number of GFAP-positive astrocytes in both CA4 and HS regions. Number of GFAP-positive astrocytes increases in an age-dependent manner, but no correlations were noted between number of GFAP-positive astrocytes and postmortem time and cause of death. Number of GFAP-positive astrocytes in the hippocampus may provide useful information for age estimation.
海马体是最易发生组织病理学变化的区域之一,此类变化可能会为法医学提供有用信息。我们发现,在连续一系列法医脑标本的海马体中经常能发现胶质纤维酸性蛋白(GFAP)阳性星形胶质细胞,主要分布在海马体CA4区和海马沟(HS)区域。本研究对这些区域的GFAP阳性星形胶质细胞进行了计数,并调查了其与年龄、死因和死后时间的关联。在CA4区和HS区,年龄与GFAP阳性星形胶质细胞数量之间均存在显著相关性。GFAP阳性星形胶质细胞数量呈年龄依赖性增加,但未发现GFAP阳性星形胶质细胞数量与死后时间及死因之间存在相关性。海马体中GFAP阳性星形胶质细胞数量可能为年龄估计提供有用信息。
