Determination of a mechanism of the coming of death by morphological methods in strangulation mechanical asphyxia

Described in the paper are morphological data characterizing the tempo and type of thanatogenesis in strangulation asphyxia. The cerebral thanatogenesis was shown to prevail in mechanical asphyxia. The results of determination of a degree of hydration of the brain by drying its samples are described. Medullary substance was demonstrated to be hypohydrated in such death.     

Determination of death mechanisms in forensic-medical examination of a corpse

Applied aspects of multivalued and modal logics served the basis for the proposed algorithm of tanatological analysis of autopsy material including formalization of semiquantitative data on changes in vital organs with further conversion of the estimated tanatogenetic coefficients in the form of probability suggestions leading to the conclusion about the kind and speed of tanatogenesis. The method is illustrated by cases from expert practice.     

Forensic medical expert evaluation of lethal poisoning with narcotics

Morphological manifestations of lethal narcotic poisoning are analyzed on the basis of results presented in "Acts of Medical Examination of Corpse" and "Expert Conclusions" on 352 cases with lethal narcotic poisoning, suspected (with good grounds) poisoning, and combined poisoning with narcotics and other agents. Causes of failure to detect narcotics in forensic chemical analysis of biological material from the corpse are enumerated.     

Morphometry of cerebral neuroglial complexes in forensic medical diagnosis of substance abuse

A method of morphometric evaluation of neuroglial complexes of the brain by relatively simple and available morphometric technique is described. The gist of the method is measuring the glial distance and glial density, which change during narcotic intoxication and abstinence. The method is addressed to forensic medical expert histologists engaged in microscopic diagnosis of such poisonings on section material.     

Features of asymmetry of paired sizes of the lower jaw as applied to osteologic human identification

The article contains craniometric data of 50 lower jaws. An asymmetry of twin sizes of the lower jaw as applicable to the tasks of osteologic personality identification is evaluated.     

Determination of hair group by preserved hair cell bulbs

Difficulties appearing in determining hair group were the reason for conducting this research for the purpose of finding additional possibilities to solve the mentioned problem. It was established that the preliminary cell coloring, related with determination of hair sex, does not influence a consequent detection of antigens. Methods or the fixation of material were selected. The most suitable reagents and their titers as well as different time periods of absorption for detecting antigens A and B are offered. All stages of examination are described in detail.     

On some peculiarities of stab wounds

The article deals with the differential diagnosis of stab injuries inflicted upon by cylindrical and conic objects with a round cross-section and with a point-shaped and cross-shaped stings as well as by sharp three-edged objects. An analysis of the obtained data leads to the conclusion on a possibility of carrying out the group identification of the mentioned stab objects according to morphological specific features of injuries.
