A novel method for cyanide quantification in human whole blood using ion chromatography with amperometric detection and its application to cyanide intoxication cases

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.

中华鳖全血呼吸爆发化学发光检测方法的建立

为进一步研究中华鳖的先天免疫能力及其机理,以酵母多糖为吞噬底物,通过对鲁米诺浓度、全血稀释度和检测温度等条件的优化,建立了中华鳖全血呼吸爆发的化学发光检测方法,并用此方法对放置不同时间的全血和稀释血液进行了呼吸爆发检测效果的比较。结果表明,鲁米诺浓度为1×10-4mol/L,检测温度为31.5℃时,以0.4~0.8μL/mL的中华鳖全血进行检测可获得理想效果。保存6 d的全血仍可检测到呼吸爆发,稀释全血放置30 h后不再产生呼吸爆发。     

论新时期公安院校形象设计

公安院校形象设计是公安院校寻求广泛社会支持、提高综合竞争力、满足不同社会群体心理诉求的总体规划。设计良好、有特色的高校形象,要在确立办学理念的前提下,通过行为识别系统规范学校运行,通过视觉识别系统提升学校形象,并根据情况分别采用以传播媒介为主、以交际为主、以服务为主、以自我完善为主等不同的模式。

从收入分配角度看中国的贫困问题

中国目前的贫困问题是经济发展问题和收入分配问题的综合表现.收入分配问题主要体现在以下三个层面:区域之间的收入分配公平问题;城乡之间的收入分配公平问题;不同收入阶层之间的收入分配公平问题.我国不公平的资源所有权格局引起了收入不公平的分配.解决收入分配涉及市场经济体制和政府对社会财富的分配体制两大类.必须把"统筹"作为解决收入分配问题的着力点.     

SCHOOLS AS COMMUNITIES: THE RELATIONSHIPS AMONG COMMUNAL SCHOOL ORGANIZATION,STUDENT BONDING,AND SCHOOL DISORDER*

Research has indicated that school factors such as communal school organization and student bonding are predictive of school disorder, with greater communal organization and greater student bonding leading to less delinquency and victimization. Data from a nationally representative sample of 254 public, nonalternative, secondary schools were used to examine structural equation models representing hypothesized relationships among communal school organization, student bonding, and school disorder. The hypothesis that communally organized schools would have less disorder held true for teacher victimization and student delinquency, but not for student victimization. In addition, the hypothesis that the relationship between communal school organization and school disorder would be mediated by student bonding was supported for student delinquency, but not for teacher victimization.
