The pathomorphology of intoxication of alcohol surrogates is described. A high frequency rate of DIC-syndrome is shown for the condition. A majority of thrombi accumulates at places with the highest concentrations of toxic substances as well as at those places, through which poisoning substances are brought out of the body, i.e. in the liver (since toxic substances are introduced perorally) and kidneys. Thrombi were detected in all internals, including the brain, in lethal intoxication. The immediate toxic effect from methanol and from higher spirits can matter in the genesis of changes, including acute swelling and chromatolysis with subsequent cell death. Exclusively cerebral or coagulopathic-cerebral types of thanatogenesis were registered in studied case of intoxication.  相似文献

Significance, of the weight and dimensions of heart as well as of fat dystrophy of cardiomyocytes and of the related detection methods is demonstrated for the diagnosis of alcoholic cardiomyopathy (ACMP). When such patients die in a state of alcoholic intoxication, the diagnosis should be death of acute alcoholic intoxication. Lethality of ACMP can be diagnosed only in those who die in the sober condition or with an insignificant level of alcohol.  相似文献

Polymorphism of mDNA D-loop central region (CR), positions 16366-0072) was studied versus hypervariable sections (HVS1), positions 16024-16365, and HVS2, positions 00073-00340, for a sample of 71 residents of the Russian Federation. Ten polymorphic positions with 56 nucleotide substitutions, 55 of which are transitions, were detect in the CR section; no insertions or deletions were found there. It was proven as possible to use the mDNA CR locus as an additional identification marker in the forensic-expert of the mDNA control region. The probability of random coincidence (RC) of haplotypes in joint typing of HVS1, HVS2 and CR made 0.0208, which is 1.4-fold less versus the same parameter for haplotypes HVS1/HVS2 (RC = 0.0284).  相似文献

Data are reported on toxicity of a majority of non-steroid anti-inflammatory drugs (NSAD), which are the most frequently used in clinical practice and whose chemical structures are different. The action mechanism and side effects of some NSAD, in particular, of diclofenac, ibuprofen and indometacin, are also in the focus of attention.  相似文献

Abstract: Guanaco (Lama guanicoe) is a protected and widely distributed ungulate in South America. A poacher, after killing guanacos in Valle Chacabuco, Chilean Patagonia, transported and stored the meat. Samples were retrieved by local police but the suspect argued that the meat was from a horse. Mitochondrial cytochrome b gene (774 pb), 15 loci microsatellites, and SRY gene were used to identify the species, number of animals and their population origin, and the sex of the animals, respectively. Analysis revealed that the samples came from a female (absence of SRY gene) Patagonian guanaco (assignment probability between 0.0075 and 0.0282), and clearly distinguishing it from sympatric ungulates (E‐value = 0). Based on the evidence obtained in the field in addition to forensic data, the suspect was convicted of poaching and illegally carrying fire arms. This is the first report of molecular tools being used in forensic investigations of Chilean wildlife indicating its promising future application in guanaco management and conservation.  相似文献

Often societies perceptions can be shaped by the media not only by what it reports but by how it is reported. This article discusses the impact that the American media has had on the social perception that the insanity defense is too often successfully used to avoid legal and criminal culpability. Many of the procedural obstacles associated with the assertion of an insanity defense are poorly understood or ignored. The article further address some of the less attractive characteristics associated with the assertion of the insanity defense that are not procedurally founded but nonetheless serve as an impediment the wide spread use of the defense. In conclusion the insanity defense is submitted as an unavoidable necessary evil in a civilized society that incarcerates its criminals.  相似文献
