title: [Age dynamics of bone tissue and its significance in forensic-medical practice in age determination].
abstract: A method was worked out designed to determine the biological age of man by using the data of quantitative histological, X-ray and X-ray-densitometry examinations of bone tissue including the technique of measuring the quantitative signs as well as a variety of mathematical model and an algorithm of their application. A new set of qualitative features was suggested, which makes it possible to attribute an individual to a certain age group; besides, an improved complex of parameters of the quantitative analysis of preparations was described, including the measurement of linear sizes and of sectional areas of microstructures in the visual field. The method is meant for determining the age at death within the forensic medical identification of personality, should it be impossible to do it by using the macroscopic features. A scheme of ontogenesis periodization is suggested for the forensic medical practice. A concept was formulated, according to which the age involution is a summarized result of the accumulation of the physiological activity cycles, endured damages and of progressing pathological processes.
