[Premature ageing in metallurgical industry workers depending on the behavioral risks existence.]

The purpose of the study is to determine the role of behavioral risks in increasing biological age indicators. A new formula for calculating the biological age (BA) was plotted, based on the data obtained for 499 employees using the V.P.Voytenko's method. It was found, that the maximum difference between biological and chronological (CA) ages are observed in workers with the lowest level of physical activity (0,54±0,3 years). In addition, there is a maximum number of health complaints in this group. With an increase in BMI by one kg/m2, the difference between biological and chronological ages grow by 0,16 of the year. We conducted a two-factor analysis of variance in order to figure out the combined effect of behavioral risks on the BA-CA value. At the maximum level of smoking and the lowest level of physical activity, the highest difference values between BA and CA are observed.

[The determination of the sequence of formation of mechanical injuries].

The objective of the present work was to highlight the problem of the sequence of formation of mechanical injuries and estimate the prospects for the application of selected modes of their solution. Various approaches to the assessment of a combination of morphological features studied in the course of forensic medical examinations are considered in order to determine the sequence of formation of mechanical injuries.

[Quantitative characteristic of the relief of skin wound edges].

This paper reports results of a morphometric study on the relief of skin wound edges with a limited contact surface resulting from an injury by sharp and hard objects. It is maintained that quantitative characteristic of the relief of skin wound edges can be used as an objective indicator of the properties of the object with which a given wound was inflicted.

[Forensic-medical significance of determination of concentration of water, potassium and sodium ions in diagnostics of infliction of sequences of stab-and-cut wounds].

The results of analyses of content of water, potassium and sodium ions by Yu. A. Medvedev's method (1988) in muscular tissue from damage region in experiment, are represented. These analyses make possible to determine sequences of stab-and-cut wounds inflicted at short time before death.
