Comparative Study
[A method for the determination of spatial orientation of wound canals caused by gunshot bullets to be applied in corpse examination].
A new approach to the determination of spatial orientation of wound canals caused by gunshot bullets is proposed and substantiated; its application for the purpose of forensic medical expertise is described. The direction of penetrating wound canals in three dimensions was determined by measuring the distance of the input and output wound holes from the level of the soles, anterior and posterior midlines, and the posterior body surface; the results of the measurements were used to construct triangles. The parameters thus obtained allowed the spatial orientation of the wound canals to be determined in three dimensions for the subsequent judgment about the relative direction of the gun barrel with respect to the human body at the time of the shot and the objective expert conclusion concerning the circumstances of firearm-related injuries.

Comparative Study
[Biochemical diagnostics of fatal opium intoxication].
Biochemical diagnostics of fatal opium intoxication remains a topical problem in forensic medical science and practice. We investigated materials obtained in the course of forensic medical expertise of the cases of fatal opium intoxication. The study revealed significant differences between myoglobin levels in blood, urine, myocardium, and skeletal muscles. The proposed approach to biochemical diagnostics of fatal opium intoxication enhances the accuracy and the level of evidence of expert conclusions.

The data on the history of development and further improvement of pneumatic weapons are presented with special reference to specific features of different types and varieties of these weapons, cartridges for them, and the sphere of their application. Investigations into peculiarities of damages caused by high-capacity pneumatic weapons to the objects of forensic medical expertise affected from different distances are reviewed. Results of forensic medical expertise and clinical studies on the structure of body injuries inflicted by gunshots from pneumatic weapons to the human body are discussed. The author emphasizes the necessity of developing up-to-date terminology and classification of gunshot injuries caused by shooting from pneumatic weapons.

Comparative Study
[The possibility of forensic medical assessment of the damage to clothes caused by a blank shots with the MP-79-9TM pistol].
The authors undertook an analysis of constructional features of standard blank and non-lethal cartridges for the MP-79-9TM pistol. The composition of gunshot products and the maximum distance over which they propagate have been determined. Special attention is given to the peculiarities of the damage caused to the target cloths (cotton and woolen) by blank rounds shot from different distances. A new chemical method was used for the first time to detect the particles of gunpowder on the victim's cloth; the possibility of its application for differential diagnostics of gunshot damages inflicted by blank and traumatic cartridges affected from different distances was estimated.
