Cyanide is a highly toxic agent that has been frequently used for suicide in South Korea. It is also used in various industrial fields, such as metal plating, in which many accidental cyanide intoxications have occurred. To overcome the disadvantages of conventional cyanide analysis methods, a simple and fast method for the analysis of cyanide in whole blood using ion chromatography (IC) with amperometric detection was developed in this study. Whole blood samples were deproteinized, diluted, and analyzed using an IC–amperometric detection system. The limits of detection and quantitation were 0.1 and 0.2 mg/L, respectively. The method showed good linearity in the range of 0.2 to 50 mg/L with R2 > 0.99. The intra- and inter-assay precision and accuracy values were <10%. The established method was successfully applied to analyze whole blood samples from three cyanide intoxication cases. 相似文献

国际刑事司法协助制度的若干新发展 总被引:2,自引:0,他引:2
HUANG Feng 《当代法学》2007,(6)
《联合国打击跨国有组织犯罪公约》和《联合国反腐败公约》对国际刑事司法协助制度的新近发展作出了一定程度的总结,特别是确立了以追缴被非法转移的犯罪所得或收益为中心的司法协助新体系,放宽了双重犯罪原则对非强制性司法协助活动的限制作用,全面推广司法协助"中央机关"的联系机制,同时,倡导各国在条件允许的情况下采纳远程视频听证和联合调查的取证新方式。这些发展所涉及的一些新规则值得加以深入研究。 相似文献

Blood previously acidified with aqueous saturated ammonium chloride solution was extracted with ethyl acetate. The dried extract was subjected to acetonitrile–hexane partition. The acetonitrile portion was analysed for the presence of acidic and neutral drugs by HPLC–DAD (200 mm×2.1 mm I.D. microbore ODS-Hypersil column) and GC–FID (25 m narrow-bore×0.25 mm I.D. HP-5 column with 0.33 μm film thickness). The protocol was found to be suitable for both clinical toxicology (including emergency toxicology) and postmortem toxicology. At least 66 drugs of interest were unequivocally identified by RRTs (HPLC) and UV spectra (DAD) match while another 12 were unequivocally identified by double RRTs match (HPLC and GC). Quantitation was facilitated by incorporating calibration blood standards in each assay batch. The five drugs most commonly encountered in clinical blood specimens (1150 cases) were: paracetamol (47.4% of the cases); chlormezanone (6.6%), theophylline (1.74%), naproxen (1.65%) and mefenamic acid (1.56%). The following drugs were detected in toxicologically significant quantities in postmortem blood specimens (245 cases): phenobarbitone (1.22% of the cases), naproxen (0.82%), chlormezanone (0.82%), theophylline (0.82%), carbamazepine (0.41%) and paracetamol (0.41%). 相似文献

We show that the probability of apprehension and punishment is usually reduced in a framework with asymmetric information, leading to more offenses being committed. A positive correlation between crime and asymmetry of information in the enforcement process is established. Some suggestions concerning the efficiency of private versus public enforcement are drawn. 相似文献

Dutch criminality and its relation to the performance of police and justice have only recently been analyzed at the macro level (e.g., at the level of municipalities or the whole country). This type of approach is a useful supplement to analyses at the micro level (that of individuals), which are more common in Dutch empirical criminological research. The main results of such a macro approach are presented in this article. We conclude that the per capita numbers of youth, divorced people, and unemployed contribute significantly to the crime rate. The police strength and solving rates are important factors as well. Analysis of the production process of the police reveals that detecting one more case of driving under the influence is far more expensive than solving one more other crime or handling one more traffic accident. The results are combined to sketch a cost-benefit approach of different strategies in allocating more resources to the police. Allocating extra resources to solving more cases of vandalism gives the best cost-benefit ratio. 相似文献

沙门菌实时荧光定量PCR检测试剂盒的研制与应用 总被引:1,自引:0,他引:1
根据沙门菌保守的fimY基因序列设计合成了引物和TaqMan探针,建立了快速检测沙门茵的实时荧光定量方法,并对反应条件进行了优化,组装成快速检测试剂盒。通过对临床样品的检测,该试剂盒的检测灵敏度达4.5 CFU(25μL反应体系),比常规PCR高100倍,而且稳定性良好,至少可以冷冻保存9个月。结果表明,所建立的沙门菌实时荧光定量PCR检测试剂盒具有操作简便、快速、特异性强、灵敏度高、重复性好、稳定性强等优点,适于大量样品的检测。 相似文献

票据金额变造的发生,不仅破坏了票据的交易安全,而且严重影响了票据在现代经济生活中的信用功能,导致票据效力的实质与形式发生异化,并由此产生票据当事人之间权利义务关系的复杂化.对票据金额变造问题的合理处置关系到票据社会功能的充分发挥.由于现行法律规则与司法解释存在一些实践中的盲点,如何从规则及操作层面上进行必要的矫正与重构,使各项规则相互衔接,并具有可预见性. 相似文献
