Role of alcohol in heroin overdose

The relationship between ethanol and risk of heroin overdosage was studied. Statistical processing of the results of forensic chemical analysis (460 expert evaluations) carried out in Chelyabinsk Regional Bureau of Forensic Medical Expert Evaluations in 2000 was carried out. The results of morphine and ethanol measurements in the blood and urine from corpses where deaths ensued from narcotic or ethanol poisoning, were analyzed. The concentrations of morphine in the blood and urine were measured on a gaseous chromatographer with mass-selective detector (Hewlett Packard HP 6890/HP-5972). Methods for measuring urinary and blood morphine are described. The results of statistical analysis demonstrated relationships between the age and ethanol concentrations in the blood and urine; blood ethanol and total urinary and blood morphine concentrations; blood concentration of free morphine and presence of 6-monoacetylmorphine in the blood. The authors conclude that the presence of ethanol in the blood together with morphine drastically augments the risk of rapid death from respiration arrest. It can also lead to a relatively high risk of overdosage in experienced narcomaniacs using heroin and ethanol.     

Crystallization of cerebrospinal fluid in cases of death from ischemic heart disease and ethanol poisoning

Crystallographic analysis of the cerebrospinal fluid (CSF) was carried out in 18 cases of death from coronary disease and 19 cases of death from ethanol poisoning. The crystallograms were evaluated visually and by the stereoscopic picture. Specific features of the CSF crystal colonies growth in subjects dead from the above conditions are determined.     

Brain acetaldehyde and ethanol: method of determination and diagnostic significance in ethanol poisoning

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.     

Effect of death from total supercooling of the body on morphofunctional state of human adrenals

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.     

Expert evaluation of aftereffects of migration of catheters in the vessels during subclavian vein catheterization

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.     

Difficulties in forensic medical evaluation of some forms of craniocerebral injury

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.     

Infrared spectroscopy of the dry residue of liquor crystallograms in various diseases

The article presents the results of an examination of the dry residue of liquor crystallograms (DRLC) using infrared spectroscopy technique. 36 spectrograms were studied. Elements of similarity and difference were revealed in the spectrograms of organic substance (antifreeze, sodium cyclamate and fatty tissue), of DRLC of the crystal-forming matter CuCl(2)x2H(2)0, of DRLC of a live person and cadaveric liquor (with no brain injury in respective case histories), of DRLC of liquor of live persons with a brain injury, of DRLC of liquor of persons who died of a brain injury and of persons who died of other causes.
