DIFFERENTIAL POSSIBILITIES OF THE METHOD OF STAINING HISTOLOGICAL SPECIMENTS BY PERLS FOR ESTABLISHING THE TIME OF FORMATION OF TRAUMATIC AND NONTRAUMATIC GENESIS HEMORRHAGES

Verifi cation of the exact time of formation of hemorrhages in the human brain (HB) of traumatic (HTG) and non-traumatic (HNG) genesis makes it possible to signifi cantly narrow the circle of suspects in the case of a crime against human life.Aim of the work. Developing of forensic criteria for the diagnosis of the age of formation of hemorrhages of traumatic and non-traumatic genesis by light microscopy of histological sections of human brain.Materials and methods. For the study used stained histological specimens of the brain from 80 corpses with a known time of hemorrhage from 2 to 15 days, according to medical documents: in case of death from HNG – 30 histological specimens (1 group), death from HTG – 30 histological samples (group 2), brain preparations in case of death from coronary heart disease were selected for control – 20 samples (group 3).Results. Analyzing the available histopreparations, it was found that the corresponding time dependences of the age of hemorrhage are not linear, but on the contrary have fluctuations in their values – uneven appearance of pigment in HB with a gradual increase in time since the formation of hemorrhages of diff erent genesis.Conclusion. Histological examination of micropreparations of the substance of the brain, stained by the method of Pearls, is not eff ective for determining the age of hemorrhage.
