Proficiency testing (external quality assessment) of drug detection in oral fluid

Eighteen external quality assessment (proficiency testing) samples were prepared from client specimens collected with the Intercept^® oral fluid collection device and by spiking drug-free oral fluid. Samples were circulated in pairs at quarterly intervals to 13 UK and USA based laboratories for analysis by a panel of OraSure micro-plate Intercept^® enzyme immunoassay kits and hyphenated mass spectrophotometric techniques. During the survey, there was a single case of non-specificity in a false report for methadone. The major errors were of lack of sensitivity relative to the concentration thresholds specified for the immunoassays. The sensitivity for overall ‘present’/‘not found’ reports calculated as true positives/(true positives + false negatives) were for the amfetamine specific assay 50%, methyl-amfetamines 93%, barbiturates 64%, cannabinoids 73%, cocaine and metabolites 100%, benzodiazepines 69%, methadone 95%, opiates 79% (opiates excluding oxycodone 93%), phencyclidine 93% and human gamma-globulin 97%. A small number of the sensitivity errors were attributable to errors in chromatographic confirmation techniques.

Spleen and portal lymphnode pathology in fatal drug addiction

Spleen and portal lymphnode sections from 86 drug addicts submitted for medico-legal autopsy at the Institute of Forensic Medicine in Copenhagen in the year 1979 were studied together with tissue sections from 24 "normal" persons. In 70% of the drug addicts the spleen weight was more than 200 g, and in 71% portal lymphnode hyperplasia was found. Birefringent foreign material was found in spleen tissue of drug addicts in 72% and in portal lymphnode tissue in 44%. Signs of antigen stimulation in both spleen and portal lymphnode tissue evaluated by the number of germinal centre and plasma cells were found in more than 80% of the drug addicts compared with about 20% of the "normal" persons. The results were related to anamnestic information of duration of drug abuse, to the spleen weight, to the occurrence of birefringent material and to the liver changes. Examination of lysozyme and immunoglobulin containing cells using the indirect preoxidase technique was performed in a total of 72 cases of spleen tissue, 59 cases of portal lymphnode tissue from drug addicts, 24 cases of spleen tissue and 18 of portal lymphnode tissue from "normal" persons. Lysozyme, IgM and IgG containing cells were found significantly more often among drug addicts than "normal" persons. The results indicate that the splenomegalia and the portal lymphnode hyperplasia often found in drug addicts are caused by continuous antigen stimulation due to repeated injections of various antigens.     

论邓小平党政关系思想及其发展——纪念邓小平诞辰100周年

邓小平党政关系思想是建立在对政党政治和以党治国的深刻体会和把握的基础上的.邓小平早在抗日战争时期就率先提出反对以党治国和正确处理党政关系的重要思想.建国后,邓小平针对因种种复杂的历史原因,以党治国的作风在党内逐渐盛行起来,逐步形成党的"一元化"领导体制的现象,对如何正确处理党政关系,进行了长时间的深入思考,提出了一系列重要思想.今天,我们正在改革和完善党的领导方式和执政方式,即用新型的党政关系逐步取代传统的党政关系,实现党政关系合理化,进一步丰富和发展邓小平关于党政关系的思想.

论权利主体

权利主体可以归结为两种基本形态--作为权利主体的自我(公民)和作为权利主体的大我(法人).个人只有取得公民的资格,拥有权利能力和行为能力,并拥有权利能力的指向物时,才能成为权利主体.大我是公意的人格化或人格体.在法人行使权利时,支配的自然过程与支配的社会过程必然发生分离.权利主体之间最基本的原则是:所有权的神圣不可侵犯、契约自由和权利主体在法律面前的平等.
