We report a case of two suicide fatalities from sodium cyanide ingestion, which showed differences in pathology and blood biochemistry. The victims were a married couple in their 70 years of age, owners of a gilding factory. They were found dead in their bedroom by a family member. Suicide notes and sodium cyanide powder were found in the room. Autopsy revealed eroded gastric mucosae in both victims. In the male, the stomach showed a previous postoperative state of partial resection, and the lungs were more congested and edematous in the male than in the female. In both victims, cyanide was detected in the blood at markedly high concentrations. In postmortem blood biochemistry, a marked elevation of cardiac troponin T, I and CK-MB was observed in the peripheral blood of the male, whereas there was only a mild elevation in the female. In the male, erythropoietin was also markedly elevated. These observations suggested a difference in the dying process following sodium cyanide ingestion between the victims; survival time may have been longer in the male than the female. The absorption of cyanide may have been a contributory factor to the difference.
我们报告了一例因摄入氰化钠导致两人自杀死亡的案例，该案例在病理学和血液生化方面表现出差异。受害者是一对70岁的已婚夫妇，是一家镀金厂的老板。他们被一名家庭成员发现死于卧室。在房间里发现了遗书和氰化钠粉末。尸检显示两名受害者的胃黏膜均有糜烂。男性的胃显示出先前部分切除的术后状态，男性的肺部比女性更充血和水肿。在两名受害者的血液中均检测到高浓度的氰化物。在死后血液生化检查中，男性外周血中的心肌肌钙蛋白T、I和肌酸激酶同工酶（CK-MB）显著升高，而女性仅有轻微升高。在男性中，促红细胞生成素也显著升高。这些观察结果表明，受害者摄入氰化钠后的死亡过程存在差异；男性的存活时间可能比女性长。氰化物的吸收可能是造成这种差异的一个因素。
