摘要: 目的 探讨大鼠死后肾上腺内突触素含量变化与死亡时间的关系。方法 建立大鼠死亡模型,在死后不同时间取出肾上腺。应用免疫组织化学方法检测肾上腺内突触素含量变化,采用图像分析系统测定突触素阳性反应物的平均灰度值,分析其随死亡时间变化的规律。结果 大鼠死亡后12h内突触素含量变化不明显,随着死后时间的延长,肾上腺内突触素含量逐渐下降。结论 大鼠死亡后肾上腺内突触素含量变化具有一定时间规律性,突触素可作为推测死亡时间的参考指标。

Abstract: Objectives To explore the changing of synaptophysin after death, and describe the relationship between the changing of synaptophysin and postmortem interval (PMI). Methods Rats were killed by cervical dislocation. Adrenal glands were taken out at different time after death. The synaptophysin in adrenal glands was detected by immunohistochemistry,and the average gray value of synaptophysin was measured by image analyzing system . The average gray values of different group were analyzed by SPSS. Results Synaptophysin in adrenal glands was stable during the first 12h after death, and then it decreased rapidly from 16h to 24 h after death. Conclusion Degradation of synaptophysin in adrenal glands varies with PMI, synaptophysin might be a new indicator for estimating PMI.
