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.     

Lethal small bowel obstruction due to pica

Up to 25% of institutionalized patients with cognitive deficiencies display pica-like behavior, with an estimated annual incidence of small bowel obstruction of 2%. We present a case based on the forensic autopsy of a 41-year-old woman who died as a result of a missed diagnosis of small bowel obstruction after ingesting a foreign body. The case underlines the importance of precaution when treating patients with cognitive deficiency and/or language deficits and gastrointestinal symptoms. In such cases, it is important to employ a liberal threshold for radiological investigations and, if possible, obtain a medical history from a person close to the patient.

加大对成都中小企业政策扶持力度的思考
