The content of ethanol and acetaldehyde in the limbic cortex and reticular formation of the brain was measured by gas-liquid chromatography in lethal ethanol poisoning. The content of acetaldehyde was significantly increased in the gyrus cinguli of the brain. Lethal poisonings occurred during any stage of ethanol intoxication. The data characterizing individual ethanol tolerance were obtained, which can be used for differential diagnosis of ethanol poisoning in practical forensic medicine. 相似文献

The morphology of adrenals was studied in cases of death from total supercooling. The intensity and terms of response are different in different morphofunctional zones of the adrenal cortex. Presumably, the terms and intensity of responses of various portions of the adrenal cortex reflect the specific features of their function regulation. 相似文献

Eleven cases with migration (escape) of catheters, inserted into subclavian veins, into the vascular bed, are analyzed by the results of forensic medical evaluations. Expert evaluation of aftereffects of the complications caused by flaws in medical care is made. Suggestions are made on evaluation of the severity of harm inflicted to health in such cases and the criteria of such evaluations are offered. 相似文献

Conclusions of 41 repeated expert evaluations of craniocerebral injuries within the framework of criminal and civil cases investigation are analyzed. Some aspects of clinical and forensic medical diagnosis of lethal and nonlethal injuries to the head, evaluation of the quality of medical care, and qualification of the severity of harm to health are discussed. Causes of typical expert errors and approaches to their prevention are shown. 相似文献

The paper describes specific morphological features of hairs from the head, beard, chest, axilla, pubis of the native population of Syria, India, Lebanon, Jordan, Yemen, Nepal, Palestine, Bahrain, Iraq and some residents of the Eastern Europe (Russians, Belorussians, Ukrainians). The hairs were studied macroscopically and microscopically (light microscopy). Digital data on hair thickness and number of lines of cuticula pattern were analysed using methods of variance statistics. Original information on some macro- and microscopic characteristics of hair has been obtained for citizens of the above countries. 相似文献

103 studies of torn aneurysms in the cerebral vessels are described. Localizations, morphological peculiarities of aneurysms as well as the nature of intracranial hemorrhages caused by torn aneurysms are presented. The authors have a critical attitude to the "acquired" theory of aneurysm development. 相似文献

The analysis of 35,312 cannabis preparations confiscated in the USA over a period of 18 years for delta-9-tetrahydrocannabinol (delta9-THC) and other major cannabinoids is reported. Samples were identified as cannabis, hashish, or hash oil. Cannabis samples were further subdivided into marijuana (loose material, kilobricks and buds), sinsemilla, Thai sticks and ditchweed. The data showed that more than 82% of all confiscated samples were in the marijuana category for every year except 1980 (61%) and 1981 (75%). The potency (concentration of delta9-THC) of marijuana samples rose from less than 1.5% in 1980 to approximately 3.3% in 1983 and 1984, then fluctuated around 3% till 1992. Since 1992, the potency of confiscated marijuana samples has continuously risen, going from 3.1% in 1992 to 4.2% in 1997. The average concentration of delta9-THC in all cannabis samples showed a gradual rise from 3% in 1991 to 4.47% in 1997. Hashish and hash oil, on the other hand, showed no specific potency trends. Other major cannabinoids [cannabidiol (CBD), cannabinol (CBN), and cannabichromene (CBC)] showed no significant change in their concentration over the years. 相似文献

Russian and foreign methods used in forensic medicine for detection of the semen in stains on material evidences are compared. The potentialities of quantitative immunofluorescence test for detection of the semen in stains on material evidences, developed at Bureau for Forensic Medical Expert Evaluations of the Leningrad region, are described. Unlike other methods used in Russia, this method detects the semen in stains in the absence of spermatozoa and in stains with very low amount of the semen. Our modification allows objective recording of the results with computer processing. The method is cheaper than its foreign analogs and its sensitivity is similar to them. 相似文献
