摘要： 目的探索毛发中外源性GHB的检测及判断的可行性,为涉GHB的鉴定提供方法和依据。方法建立毛发中GHB的GC/MS分析方法,并通过动物实验,考察毛发中内源性GHB的质量分数范围、外源性GHB在毛发中的时间过程以及给药剂量、毛发颜色与毛发中GHB的质量分数关系。结果豚鼠和中国人黑色毛发中内源性GHB质量分数分别为(3.01±1.41)ng/mg(n=28)和(1.02±0.27)ng/mg(n=20);摄GHB后毛发中GHB质量分数明显增加且与给药剂量呈正相关性;GHB在毛干中呈窄带分布;深色毛发中GHB质量分数高于浅色毛发。结论毛发中GHB的检测适用于GHB滥用和中毒的法医毒物学鉴定;根据毛发中的GHB质量分数和毛发分段分析可判断GHB的来源。

Abstract: Objective The possibility for the identification of GHB administration through hair analysis was investigated to provide method and information for toxicology examination of GHB. Methods A GC/MS assay for GHB in hair was developed. Endogenous levels of GHB in hair, time course of GHB in hair, relationship between GHB levels in hair and hair color or administration dose were also established by guinea pig model. Results Endogenous levels of GHB in guinea pig black hair and human black hair were (3.01±1.41) ng/mg (n=28) and (1.02±0.27) ng/mg (n=20), respectively. GHB levels in black hair were increased by GHB administration and related with drug dosage, and also much higher than in brown and white hair. Conclusion Analysis of GHB in hair is suitable for investigation of GHB abuse in forensic toxicology and GHB level in segmental analysis compared with endogenous level of GHB may provide useful information about GHB administration.
