[Possibilities of scanning electron microscopy with energy-dispersion analysis in the study of gunshot injuries]. / Vozmozhnosti skaniruyushchei elektronnoi mikroskopii s energodispersionnym analizom pri issledovanii ognestrel'nykh povrezhdenii.

The purpose of our work was to assess the capabilities of the SEM in the framework of expert studies of gunshot injuries of targets made of cotton fabric. In the study of experimental injuries resulting from shots fired from the KO-M1-98 carbine with 8x57JS cartridges at various distances (from the stop to 3.5 m), the presence of features of the soot morphology was established, by which it is possible to judge the distance of the shot. Thus, by examining fragments of target tissue from the central and peripheral zones of soot deposition, electron microscopy revealed a change in the ratio, intensity, and topography of soot particles. The energy-dispersion analysis revealed that with increasing distance, the number of chemical elements that make up the capsule decreases, with the exception of tin, which has an unstable inversely proportional bond.

[VISCERAL LEISHMANIASIS IN A THREE-YEAR-OLD CHILD].

The paper describes a clinical case of visceral leishmaniasis in a three-year-old child who Was born and is a permanent resident in Penm. Its clinical symptomatology; laboratory and instrumental findings; stages of a diagnostic search for fever of unknown origin concurrent with hepatosplenomegaly and pancytopenia; differential diagnosis with hemoblastosis; and an epidemiological history are detailed. Visceral leishmaniasis was diagnosed at examination of bone marrow specimens. The paper presents the positive results of combination etiopathogenetic treatment, which are confirmed by the time course of clinical changes and laboratory findings.
