摘　　要：目的：探讨人死后胸骨骨髓脂质含量的变化与PMI的关系。方法：离体人胸骨置于32C培养箱中不同的时间点取材，病理切片，苏丹Ⅲ染色，利用计算机图像分析技术研究脂质变化与死亡时间的关系。结果：死后1～9d，染色逐渐变浅淡，至10d后已观察不到，脂质含量随死亡时间延长而下降，且二者之间存在线形关系。结论：人胸骨骨髓脂质含量对死亡时间的推断具有重要的参考价值。Objective： To study the relationship between content of lipid in bone marrow of sternum and postmortem interval. Methods： In 32C humidity 85%o lipid content in the marrow of sternum was determined from 1 to 9 days after death by improved Sudan Ⅲ histochemical method with image analysis. Results： The amount of lipid decreased gradually with the prolongation of postmortem interval. It gradated to its minimum at 10 days in this group after death. There was a linear relationship between the decrease rate of the lipid and postmortem interval. Conclusion： The content of lipid reduced with extending time.
