[75 years in the service of Karelia: to the anniversary of the State Medical Institution of the Republic of Karelia Bureau of Forensic Medical Examination]

The article is dedicated to the 75th anniversary of the State Budgetary Healthcare Institution of the Republic of Karelia «Bureau of Forensic Medical Examination». The history of the formation of the forensic medicine service in the Republic of Karelia is briefly described. The data on the heads of the service and well-known forensic experts, the organizers of the forensic medical examination in Karelia, the course of forensic medicine of Petrozavodsk State University, the role of its employees in the work of the State Medical Institution of the Republic of Karelia «Bureau of Forensic Medical Examination» are presented. In addition to available literature sources, archival materials of employees and veterans of the forensic medical service of Karelia were used.

[On the question of justifying the choice of a model-object for studying the dynamics of impedance in the postmortem period]

Objective - to compare the temporal dynamics of the tissue impedance of human and pig corpses under the same conditions to substantiate the further use of pig corpses as model objects. At the first stage, we studied the tissue impedance values obtained on 4 pig cadavers with a known date of death measured with a Keysight U1731 parting. The necessity of using a model object for studying the dynamics of impedance in the postmortem period has been substantiated. An exploratory analysis was carried out that allows to put forward a hypothesis about the existence of the impedance values (absolute indicators) and dispersion coefficients (relative indicators) dependence on the time of death, and also suggests that the combination of impedance values and the corresponding coefficients can be used to judge its duration for the objects under study.
