A simple and sensitive method is described for quantitative analysis of chlorpromazine in blood, serum, urine and tissue homogenate. The chlorpromazine cation radical produced by adding perchloric acid and 2,3-dichloro-5,6-dicyano-p-benzoquinone to the sample can be detected by the ESR method at room temperature. The sensitivity limit is 10 ng, that is, 20 μl of the solution containing 0.5 μg chlorpromazine/ml. The time needed for the measurement is within 10 min. The chlorpromazine radical thus produced is very stable; for example, 95% of the radical was observed after 24 h. The advantage of this method is discussed by comparing with the ordinary spectrophotometry which requires the purification of the sample. 相似文献

Although there has been speculation regarding the pervasiveness and nature of judicial decisions regarding life-sustaining medical treatment (LSMT), no attempt has been made to empirically assess their prevalence or the issues they address. An exploratory study utilizing a mail survey of a nationwide random sample (N = 905) of state trial court judges was conducted to provide initial information regarding this decision-making process. Twenty-two percent of the responding judges had heard at least one LSMT case, and judicial review did not appear endemic to particular states. The number of judges hearing LSMT cases dropped from 1975 to 1981 but has increased since then. Three major issues predominate: patient competency, appointment of a surrogate decisionmaker, and resolution of the ultimate issue of forgoing LSMT. Relatively few cases either contested a prior directive's validity or involved imposing sanctions for instituting or forgoing LSMT. Although subject to different interpretations, the results suggest the courts are having a significant impact on certain aspects of the LSMT decision-making process. However, the infrequency with which any one judge is called upon to make an LSMT decision causes concern about the judiciary's ability to respond in a timely and appropriate manner. With their potential for a profound effect on the actions of health care providers, greater attention to this decision-making process is warranted. 相似文献

Poppy seed ingestion as a contributing factor to opiate-positive urinalysis results: the Pacific perspective. 总被引:2,自引:0,他引:2
C M Selavka 《Journal of forensic sciences》1991,36(3):685-696
The possible contribution of poppy seed foods to positive opiate urinalysis results, especially from foods available in the Pacific Rim area, has recently become an issue for the U.S. Army Forensic Toxicology Drug Testing Laboratory in Hawaii. To assess the likelihood of this possible contribution, seven different poppy seed food products were consumed by male and female volunteers, and urine specimens were collected at time increments up to either 24 or 72 h. Specimens were evaluated for opiates using Roche Abuscreen radioimmunoassay (RIA), and all RIA positive specimens were analyzed for morphine and codeine using gas chromatography/mass spectrometry (GC-MS). Poppy seed cake, bagels, muffins, and rolls did not contain sufficient quantities of poppy seeds to give rise to opiate positive specimens by U.S. Department of Defense (DOD) GC-MS cutoff levels (morphine = 4000 ng/mL, codeine = 2000 ng/mL), although a number of specimens were positive by National Institute on Drug Abuse (NIDA) cutoff levels (morphine and codeine = 300 ng/mL). However, ingestion of poppy seed streusel or Danish pastry led to confirmed morphine and codeine positive specimens, irrespective of the use of DOD or NIDA confirmation cutoff values. In addition, significant amounts of codeine were observed in a number of these specimens. These findings argue against the unqualified application of previously published quantitative guidelines for eliminating poppy seed ingestion as a possible cause for a positive opiate urinalysis result. 相似文献

During 2005, the European Union and China marked 30 years of diplomatic relations with much fanfare. Celebrations surrounding
the anniversary however belied the fact that throughout most of this period the European Union and China remained largely
aloof from one another. The strengthening of EU foreign policy over time, as well as the economic reforms and new outward
orientation exhibited by China have changed the dynamics of the relationship. Both sides are increasingly recognizing the
potential mutual benefits that can be accrued from a closer relationship. This paper assesses EU-China relations from both
economic and political perspectives. In terms of economics, it is clear that the EU must build stronger relations with China
if it is to accrue the benefits of access to an expanding market with over one billion people. To do so successfully however,
the EU will have to reconcile the economic and political components of its foreign policy. The EU continues to challenge the
Chinese government to reform its practices on a number of issues including human rights, democratic reform, and Tibet, all
of which remain bones of contention. How the EU achieves the balance between political constraints and economic opportunities
is the primary focus of this paper.

Offender assessment and classification is becoming an increasingly important part of correctional supervision and intervention. Over the last several decades, several different methods and “generations” of offender classification have emerged. Of most value appear to be third-generation, actuarial, dynamic risk/need assessments. With any new correctional strategy, however, there is a need to investigate the use of these risk/need assessments on offender subgroups in order to inform issues, such as reliability and prevalence of criminogenic risk factors. The present study utilized data that were gathered using the Level of Service Inventory-Revised (LSI-R). Results and comparisons of these assessments were investigated and presented for Native American and non-Native American offenders as well as male and female offenders. Discussion of the results, implications, and recommendations for further research are presented. 相似文献

*2004年11月,美国总统乔治.W.布什在阿根廷参加第4届美洲国家首脑会议期间,受到了来自民众的强烈抗议。这是自1958年时任美国副总统的理查德.M.尼克松在委内瑞拉被愤怒的民众投掷石块以来,美国政府高级官员在拉丁美洲受到的最差的待遇了。在委内瑞拉总统乌戈.查韦斯和玻利维亚总统候选人埃沃.莫拉莱斯的鼓舞和煽动下,数万名民众举行集会,谴责美帝国主义和已遭搁浅的美洲自由贸易区计划。布什会受到强烈抗议,事先并非毫无征兆。在他出访前夕进行的民意调查显示,53%的南美洲人和87%的拉美“意见领袖”(Opinion Leaders)对美国总统表示反感,… 相似文献
