Diagnostic evaluation of main signs of liquor crystallograms in live subjects with craniocerebral injuries of different severity

Liquor samples from 159 live subjects with craniocerebral injuries were analyzed. Forty-four patients had brain concussions, 30 light contusions of the brain, 43 medium-severe contusions of the brain, and 42 severe contusions of the brain. Crystallograms were evaluated by 37 signs detected visually and by stereoscopy. The main diagnostic criteria for evaluation of the severity of craniocerebral injury were defined.     

Comparative characteristics of angulometric parameters of teeth and dentitions in terms of personal identification

Angulometric teleroentgenographic characteristics of teeth were compared for 158 subjects. A computer technology of calculation and assessment of 47 angular (quantitative) parameters characterizing spatial position of the teeth and jaws is proposed. This complex of parameters can be used as an additional test in personal identification.     

Quantitative assessment of brain hydration in determination of death speed and type of tanatogenesis in forensic medical practice

Brain hydration was determined in death of strangulation mechanical asphyxia, acute alcoholic poisoning, acute poisoning with opiates, cancer of stage IV, coronary heart disease with acute heart failure, hemorrhagic stroke. Brainstem edema (BSE) occurred in 69.2% cases (upper BSE - 20.2%, lower BSE - 17.3%, BSE of the all parts - 31.7%). BSE was present in all cases of opiate poisoning; 52.9% cases of hemorrhagic strokes, 61.3% cases of coronary heart disease. The data obtained show prevalence of brain tanatogenesis in death of the above diseases. Hypohydration and hyperhydration of the brain were observed in short and slow agony, respectively.     

The role of retroperitoneal hematomas in thanatogenesis of pelvic trauma

A brief statistical analysis of the pelvic hematomas' evolution in traumas with various localizations is presented in the article. The current published data were made use of to describe the state-of-art for the time being. Finally, problems related with the forensic-medical aspects of the issue are defined, and methods to cope with them are appropriately suggested.     

Advanced technique for the preparation of bone and tooth tissue for molecular-genetic expert tests

Laboratory schemes related with the procedure of purifying the osseous and dental samples by applying the dental drilling machine, dental technical carborundum shapes, fogging discs and hard-alloy dental drills were made use of to improve the quality and effectiveness of the mentioned schemes used prior to molecular-and-genetic expertise tests.     

The possibilities for simulation in the expert assessment of the circumstances of the causes of head trauma

Some aspects of simulation experiments in forensic medicine are discussed, specifically those in studies of biomechanics and expert evaluation of the probable circumstances of a head injury caused by falling on a plane from a standing posture. Based on mathematical simulation and multifactorial analysis of physical parameters characterizing the process of falling (inertia, angular velocity, etc.), the authors prove the possibility of differentiating between spontaneous falling of a victim and falling caused by an outer force, and estimating the value of this force.     

Fatal doses and concentrations of drugs in biological objects

Information on the lethal doses and concentrations of drugs in biological objects is essential for the diagnosis of drug poisoning. Methods for measuring the concentrations of some drugs in the blood and urine have been developed and tables of lethal doses, concentrations, and metabolism coefficients for drugs most often occurring in forensic medical practice are offered. A method for estimating the drug dose which led to a lethal outcome is suggested.
