摘　　要：应用傅里叶变换红外(FTIR)光谱分析研究了近死亡期皮肤损伤活性差异。生前5min组,死后5min组,正常组的FTIR光谱的峰形、峰高有明显差异:(1)与脂类有关的3007和1745cm-1谱带的峰高,生前伤比死后伤增强。(2)与碳水化合物相关谱带1160cm-1的峰高,生前伤比死后伤明显升高。(3)1640cm-1谱带为蛋白质相关的酰胺Ⅰ带,损伤组峰高要低于正常组,生前伤中最低。这一结果表明,FTIR光谱分析技术有望成为法医近死亡期皮肤损伤活性判定的有效方法。Fourier transform infrared spectroscopy （FTIR） was applied to study the difference of vital reaction following skin injury close to death in mouse and provided the evidence for forensic practica The results demonstrated that vital 5 min, postmortem and normal groups showed significant differences in the wave form and intensity： （1） The intensity at 3 007 and 1 745 cm^-1 related to lipid for the vital injury was higher than that for the postmortem; （2） The intensity at 1 160 cm^-1 related to carbohydrate for the vital injure increased more compared to the postmortem; （3） The intensity of the band at 1 640 cm^-1 related to amide Ⅰ band for the injury groups was higher than the normal, but it was the lowest for the vital injury. These results show that it will be possible for FTIR to become an effective method to determine the vital reaction of injury close to death in forensic practice.
