The author compares the properties (caliber, power, speed) of the firearm projectiles and bullets with the high muzzle energy shot from pneumatic weapons. Results of experimental observations with the use of biological and non-biological objects are presented. The entry and exit wounds in the skin and bones as well as the resulting damage inflicted to the tissues and the character of bullet deformation are described.

The objective of the present study was to identify morphological features of stab and slush injuries to the skin inflicted with the ragged-spine knife. Visual and stereoscopic examination of experimental skin injuries to the biodummies revealed a number of peculiar characteristics of such wounds. Their severity is shown to depend on such factors as pressure on the spine or the blade.

We have developed the criteria allowing to determine the distance of a gunshot from limited-range firearms (an IZh-79-9TGM pistol with the elastic bullet cartridges) based on the morphological characteristics of the wound and the results of inductively coupled plasma mass spectrometry. The method has been developed for the quantitative determination of barium, lead, and antimony in the targets depending on the gunshot distance.

The present paper is devoted to the forensic medical estimation of the harm to health inflicted to the victims of ankle joint injuries with reference to the role and significance of traditional goniometry in the practical work of traumatologists, orthopedists and forensic medical experts. It is shown that the use of goniometric data alone as the sole criterion for the estimation of the harm to health in case of ankle joint injuries is unjustified and hampers further development of this field of forensic medicine.

The analysis of the definition of forensic medicine and its evolution during the past 300 years is presented. The special character of forensic medicine, its subject-matter, scope of research, procedures, goals and targeted application of forensic medical knowledge are discussed. The original definition of the notion of "forensic medicine" is proposed.
