METHODS TO DETERMINE COMPLEX DEGREES OF MUTUAL ANISOTROPY FOR THE DIFFERENTIATION OF HEMORRHAGES IN THE HUMAN BRAIN SUBSTANCE RESULTING FROM TRAUMATIC AND NON-TRAUMATIC GENESIS
Keywords:ischemic cerebral infarction, hemorrhages of traumatic and non-traumatic genesis, forensic medicine
An issue that is often debated in forensic traumatology is the differential diagnosis of hemorrhages into the human brain substance (HBS) of traumatic and non-traumatic genesis.
Objectives. This study aims to identify new criteria for objective forensic differentiation of hemorrhages of traumatic origin, cerebral infarction of ischemic and hemorrhagic genesis by using the method of complex degree of mutual anisotropy. For this study native sections of HBS from 125 corpses were used in the case of: death from coronary heart disease - 35 (28%) of native sections (Group 1 - control); hemorrhages of traumatic genesis - 30 (24%) sections (Group 2); ischemic cerebral infarction - 30 (24%) native sections(Group 3); and hemorrhages of non-traumatic genesis - 30 (24%) native sections (Group 4).
Results. The statistical moments of the third and fourth orders, which characterize the asymmetry and excess of the complex degree of mutual anisotropy module size distributions, the strength of the method of polarization-correlation microscopy in the differentiation of the samples of the histological sections of the brain of control and experimental groups reached a good level — 87%-90%.
Conclusion. The method of complex degree of mutual anisotropy allows differentiating with great precision the genesis of hemorrhage into the substance of the brain.
