In connection with the variability and as a consequence of the poor diagnostic value of the external (planimetric) parameters of the palm traces, the new system of absolute and relative dimensional attributes based on the stable palmoglyphic reference points is considered. The purpose of the present study was the search for the new biological markers of biological age. The material for the study consisted of the palm prints obtained from 180 men and 120 women of the Caucasoid stock at the age from 16 to 80 years. The use of the descriptive statistics methods yielded the basic statistical characteristics of the traits being investigated and revealed the limits of their variability in the groups of men and women belonging to the age groups from 16 to 29 and from 30 to 80 years. The method of threshold values made it possible to identify 13 attributes the excess of which allows, with the probability of no less than 0.95, to perform diagnostics of the age group of an unknown subject.

This article was designed to consider the congenital age-specific features of palm dermatoglyphics in the adults subjects (including the type of the papillary patterns, axial tri-radii, the termini of palmar main lines, the rudiments of palmar lines, the dermatoglyphic ridge count between the stable anatomical structures). The objective of the study was to look for the new diagnostic markers of the biological age. It included the identification of the palm prints obtained from 180 Caucasoid men and 120 women at the age varying from 16 to 80 years. The results of the mathematical and statistical analysis provided the basis for drawing up the list of 18 attributes of palm dermatoglyphics significantly (p<0.05) differing in the frequency of occurrence between the representatives of individual age groups. The methods are proposed allowing to use these findings for the expert evaluation of the age of unknown subjects.

An overview of dermatoglyphic studies for the purpose of forensic medical expert examination is presented with special reference to their main aspects, such as topics and objects of the surveys, their scope and methods, relationships with other disciplines.

In experiments on animals and isolated livers from human cadavers an opportunity of using a direct ascending cholegraphy for roentgenological diagnosis of gunshot injuries of the liver was studied, rather demonstrative roentgenograms, photographs given in the paper being obtained.
