在本研究的１３个案例中，怀疑原发性脑干伤死亡的５例，明确死因的８例，其中严重闭合性颅脑损伤２例；缢死１例，失血性休克１例，电击２例，海洛因中毒２例。用ＬＳＡＢ法对１３例脑干的中脑、脑桥、延髓各部ＦＮ进行检测。结果显示５例怀疑为原发性脑干伤、２例严重颅脑损伤、２例海洛因中毒死者的脑千部位的神经元内均可见ＦＮ的异常沉积，其它各例未见ＦＮ的异常沉积。结果表明；ＬＳＡＢ－ＦＮ法是诊断原发性脑干伤早期死亡灵敏但非特异的形态学指标。
In the 13 cases of this study, 5 patients were suspected of death from primary brain-stem injury, 8 patients were confirmed as having a clear cause of death, 2 were severe closed head injury, 1 died of hemorrhage, 1 was hemorrhagic shock, 2 was electric shock Cases, heroin poisoning in 2 cases. Using the LSAB method, 13 cases of brain stem, midbrain, pons and medulla oblongata FN were detected. The results showed that 5 cases of suspected brain stem injury, 2 cases of severe brain injury, 2 cases of heroin poisoning of the brain parts of the brain can be seen abnormal neurons within the deposition of FN, FN abnormalities were not seen in other cases. The results showed that LSAB-FN was a sensitive but nonspecific morphological indicator for the early diagnosis of primary brain stem injury.
