Clinical and histopathological examination of experimental bite marks in-vivo.

摘要: Under rigorously controlled laboratory conditions, mechanically induced simulated human bite marks were made on pig skin to enable the clinical and histopatholgical study of experimental in-vivo. A series created abdomen thorax live anaesthetized juvenile pigs at specific times just prior after death. Following release biting force observations antemortem wounds revealed slow diminishment indentations presumably due dermal elastic recovery. Minutes euthanasia animals, teeth from postmortem faded rapidly. After process animals placed either right or left side this was maintained until necropsy examine for dependant non-dependent differences. All mark injuries located pattern characteristics. However, dependent whether in areas livor mortis, no clear visible. Histologically, each specimen categorised by presence absence extravasated red blood cells fatty muscle layers. The histopathological findings correlate with regard muscular erythema cells. It is clinically difficult comment temporal relationship a relation time death affected blood-pooling seen side. In these situations, studies could be reliable alternative provide information regarding injuries.
