A man in his 30s injected insulin several times into his abdomen and was found dead several hours later. Micropathological findings showed alveolar injury with hemorrhaging and cerebral parietal lobe nerve cell edema. Biochemical examinations showed that the blood insulin level was high, significantly so at the insulin injection sites. The blood glucose and C-peptide levels were low. The insulin level in the kidneys was low. In forensic medicine, a postmortem diagnosis of insulin subcutaneous injection is often difficult. When insulin injection is suspected, particularly high insulin levels can be expected at the insulin injection site, rather than in the blood.
一名 30 多岁的男子多次将胰岛素注入腹部，数小时后被发现死亡。显微镜下病理检查显示肺泡损伤伴出血和大脑顶叶神经细胞水肿。生化检查显示血液胰岛素水平升高，在胰岛素注射部位尤为明显。血糖和 C 肽水平低。肾脏中的胰岛素水平低。在法医学中，胰岛素皮下注射的死后诊断通常很困难。当怀疑胰岛素注射时，特别是在胰岛素注射部位，而不是在血液中，可以预期胰岛素水平会很高。
