SU1573381A1 - Method of pathoanatomical diagnosis of death from overcooling - Google Patents

Abstract

The invention relates to medicine, namely to forensic medical examination. The aim of the invention is to improve the accuracy of diagnosis of hypothermia death. The goal is achieved by examining the intralobular bronchi, in which the area of the bronchus bounded by the adventitia is determined, and the area of the bronchus bounded by the lamina propria of the bronchial mucosa. Next, an indicator of the ratio of these values is calculated, according to which death from hypothermia is diagnosed. The method allows the investigative authorities to be correctly oriented at the cause of death.

(54) METHOD FOR PATHOLOGICAL ANATOMIC DIAGNOSTICS OF DEATH OVERCOOLING

(57) The invention relates to medicine, namely to forensic

expertise. The aim of the invention is to improve the accuracy of diagnosis of hypothermia death. The goal is achieved by examining the trifoliate bronchial tubes, in which the area of the bronchus limited by the adventitia and the area of the bronchus limited by the bronchus mucosa is determined. Further, an indicator of the ratio of these values is calculated, by which death from dwelling is diagnosed. The method allows the investigative authorities to be correctly oriented at the cause of death.

The invention relates to medicine, namely to forensic medical examination.

The purpose of the invention is to improve the accuracy of the method.

The method is carried out as follows.

Tissue was taken from the lung, and histological preparations were prepared. Next, on the lung section, the intra lobular bronchi are determined, then they determine the total area of the bronchus, limited by the adventitious sheath, and the area of the bronchus, limited by the lamina propria of the bronchial mucosa, then the ratio of these indicators is calculated, while 69, are diagnosed with death from overcooling.

Example 1. Forensic medical examination of a corpse. The study was conducted 18 hours after death. On the body, there were injuries to the nature of bruises and abrasions. These injuries are in vivo, have arisen from the action of solid blunt objects shortly before the onset of death, they do not cause a connection with the mixture, and in living persons according to the degree of severity they are classified as minor injuries that did not entail short-term health disorder. The complex of macroscopic signs indicating death from general overcooling was not revealed (the indicator is 1.4).

Additional research methods were carried out.

Ethanol is present in a concentration of 3.57% and 5.31%, respectively, which usually corresponds to the alcohol excretion of a severe degree and does not exclude the possibility of death from acute ethanol poisoning.

Example 2. A corpse has areas of the lung taken from areas containing intralobular bronchi. Objects are placed in vessels containing 10% formalin solution for fixation for 24 hours. After histological wiring, pieces of the internal organs are embedded in paraffin, sections are made in a sled microtome, 8-10 microns thick, placed on slides, stained with hematoxylin -Eosin, and the pieces of the lungs, painted according to Van Gieson, are poured into polystyrene and covered with cover glasses. Examine stained histological sections using a biolam microscope equipped with an ocular compensating eye with a grid - K 10 with an x80 microscope magnification. In the preparations of the lungs there are intralobular bronchi that fell into a section in the transverse or close to this section with an asterisk-shaped lumen. With the help of a grid - K 10x, the areas limited by the corresponding adventitia of the bronchi and the lamina of the mucous membrane are defined in arbitrary units. In this example, the areas bounded by the adventitia of the three studied intralobular bronchi are 75; 81.9; t 72.4 sr. unit; the areas, limited by the lamina propria of the mucosa, are respectively 23.4; 24.1; 19.5 conv.

Conclusions: the cause of death gr.P. There was a general overcooling. The onset of death was facilitated by alcohol exploration.

The method makes it possible to increase the accuracy of diagnosing hypothermia deaths, including cases associated with glaciation, which allows the investigators to properly orient the cause and circumstances of the death.

Claims (1)

Invention Formula The method of pathoanatomical diagnostics of death from overcooling, by examining lung tissue, is characterized in that, in order to improve the accuracy of the method, intralobular bronchi are examined, which determine the total area of the bronchi, xa, limited by the advenidial membrane, and the area of the bronchus, limited with a bronchus mucous membrane of its own, then the ratio of these indicators is calculated, and at this rate of 3.4TO, 69, death from overheating is aggravated.
