Evaluation of the Abbott TDx-radiative energy attenuation (REA) ethanol assay in a study of 1105 forensic whole blood specimens

In a preliminary study to determine the applicability of the Abbott radiative energy attenuation (REA) method for the quantification of ethanol in whole blood specimens it was concluded that a larger number of samples was required to evaluate the method, particularly for use in forensic toxicology applications. In this study, 573 blood specimens from suspected driving while intoxicated individuals (DWI blood) and 532 postmortem blood specimens (PM blood) were analyzed by the REA method and a headspace gas chromatographic method (GC) currently used in this laboratory. "Negative" specimens (less than 10 mg/dL by GC) and "positive" specimens (greater than or equal to 10 mg/dL by GC) in each category were analyzed. Linear regression analysis comparing the REA values with the GC values was performed for each type of blood specimen. The equation obtained for DWI blood specimens was REA = 0.943 GC + 1.54; the equation for PM blood specimens was REA = 0.980 GC + 2.76. The correlation coefficient for each group was greater than 0.99. The data suggested that a limit of detection of 10 mg/dL could be applied for DWI blood specimens, while 20 mg/dL would be recommended as the limit of detection for PM blood specimens.     

A case of strangulation with postmortem amputation of the penis

A case of homicide with postmortem amputation of the penis was described. The penis found later in a home freezer in the apartment of the culprit showed "zigsaw" fit to the victim. In order to substantiate the morphological findings, phenotypes of three isozymes, phosphoglucomutase1 (PGM1), phosphogluconate dehydrogenase (PGD), and esterase D (EsD) together with ABO blood type were determined in the skin of the penis amputated. All of the four genetic markers determined with the penis were the same as those determined with heart blood of the victim.     

多重PCR检测FFv三个基因座在景颇族人群中的遗传多态性

短串联重复序列（STR）是由几个碱基对作为核心单位串联重复形成的一类DNA序列,作者将3个STR基因座在同一反应体系中进行互不干扰的复合扩增,采用高分辨率的聚丙烯酰胺凝胶电泳分离、银染法显影技术,对云南省景颇族的F13A01,FESFPS和vWA等3个基因座等位基因的基因频率进行了调查,获得了满意的结果,显示了广阔的应用前景。F13A01基因座观察到8个等位基因、13个基因型;FESFPS基因应观察到7个等位基因、18个基因型;vWA基因应观察到7个等位基因、21个基因型。

甲醛固定组织中DNA提取与扩增技术的初步研究

目的：探索从甲醛固定组织中提取并扩增DNA的方法。方法：采用高pH缓冲液,结合有机溶剂法抽提DNA,选择扩增片段较短的DQa位点作为检测位点。结果：甲醛固定组织中的DNA降解程度随浸泡时间的延长而加重,但浸泡1、5、10个月的3份心脏组织均获得了240bp的扩增产物。     

Analysis of 226 cases of psychosis involved in lawsuit

226 cases of psychosis involved in lawsuit were investigated. The problem of forensic identification was discussed. Some suggestions were given to raise the quality of the forensic identification in psychosis.     

A survey of the social and psychological factors of the heroin dependence

The survey studied 100 dependence about their age, marriage, occupation, the way of heroin taking, history of heroin taking, and the reason of the first heroin taking. The data showed that most dependence were young or middle aged men, or people unable to graduate from junior middle school, self-employed laborers and unemployed. Dependence of cadres and people with better education were increasing. The heroin injection is becoming popular.
