Possibilities of differential diagnostics of livores mortis and bruises at different stages of the time since death using laser polarization methods

One of the urgent problems forensic medicine remains detection hemorrhages in soft tissues during examinations decayed corpses, because late cadaveric phenomena significantly distort primary morphological picture, thereby complicating examination. A change color skin after a few days or later death most often makes macroscopic diagnosis impossible, particular, their differentiation with livores mortis.The aim work. To investigate possibilities detecting and differentiating bruises areas mortis at different stages time since by Muller matrix analysis polarization images optically anisotropic polycrystalline networks human tissues.
 Material methods. Skin sections subcutaneous fatty tissue were collected from corpses persons who died mechanical injuries. The obtained samples divided into two groups: intact hypostasis imbibition existing known death. Tissue research was carried out using laser polarimeter standard scheme.Results. According to results study, it established that values statistical moments 3rd 4th orders (S3, S4) intensity distributions show statistically significant (р1<0,001) difference between when are combined. asymmetry excess (S3 1,23±0,032 1,56±0,038; S4 1,49±0,024 1,94±0,021) for changed increasing interval Similar changes S3 1,54±0,031 1,83±0,037; S3from 1,82±0,026 2,11±0,023) localization bruises.Conclusions. Thus, can be stated application Mueller method is effective spots postmortem conducting order.
