Acute arsenic poisoning: clinical, toxicological, histopathological, and forensic features

This report describes a suicide case by acute arsenic intoxication via intravenous injection. A 30-year-old woman injected arsenic As (V) (sodium arseniate disodique: Disodium Hydrogena Arsenik RP) in a successful suicide attempt. Three hours following administration, the woman developed severe digestive symptoms. She was admitted to a hospital and transferred to the intensive care unit within 12 h of the massive administration of arsenic. Despite therapeutic efforts, over the next 2 h she developed multiorgan failure and died. A postmortem examination was performed. Pulmonary edema and congestion of liver were apparent. As (V) and As (III) were determined by high performance liquid chromatography and inductively coupled plasma mass spectrometry after mineralization of samples by concentrated nitric acid. Toxicological analysis revealed high concentrations of arsenic in biological fluids as well as in organs. Histopathological examination showed a typical indication of myocarditis. These findings were in agreement with acute arsenic poisoning. The symptoms developed by this young woman (intoxication by intravenous administration) were comparable to oral intoxication. The clinical signs, survival time, and administration type are discussed in light of the literature on acute and chronic arsenic poisoning.     

低分子量肝素生物利用度的研究

灯盏花注射液对脑缺血再灌注损伤的保护作用

目的：研究灯盏花注射液对避灶性脑缺血再灌注损伤的保护作用及机制。方法：采用大鼠局灶性脑缺血再灌注模型，观察灯盏花注射液对血清胞浆酶及fos蛋白表达的影响。结果：脑缺血现后血清胞浆酶含量及foa蛋白表达显增加（P＜0．01）；灯花注射液可明显降低脑缺血再灌注后血清胞浆酶含量，下调fos蛋白的高表达（P＜0．01），结论：灯盏花注射液对脑缺血再灌注损伤有保护作用，其机制可能与其犯罪 清胞浆酶及下调fos蛋白高表达有关。

Increasing Allele Detection by Altering the Quantity of Internal Lane Standard

Electrokinetic injection (EI) is the primary method used in forensic laboratories to load amplified PCR product in capillary electrophoresis for short tandem repeat (STR) fragment separation. Because all samples subjected to capillary electrophoresis use internal lane standard (ILS), this study investigated the consequence of varying the volume of ILS and its effects on allele peak heights and number of alleles detected. Results demonstrated that when the volume of ILS is reduced, the average peak height and number of alleles increased, thereby increasing the sensitivity of the detection method. Sizing anomalies were observed; however, they did not adversely affect accuracy and precision. The method developed in this study offers a simple and universal procedure to increase the alleles detected in forensic STR analysis. Reducing the volume of ILS to achieve greater sensitivity is applicable to all STR amplification kits and capillary electrophoresis instruments currently used in forensic DNA analysis.
