Abstract |
Distinguishing between injuries resulted from electrical current versus thermal energy is not only a difficult, but also a controversial issue in forensic medicine practice.In this study, an electrical current and a cautery were applied to dorsal skins of 10 rats and biopsies were taken from the injured sites as well as normal skin. In the histologic sections; some planimetric variables such as the perimeter, area, diameter equivalent circle, minimum feret, maximum feret, and the circular form factor of the nuclei located in normal and injured epidermis were measured with the aid of the computer-assisted image analysis.When compared with normal skin, all of the variables -nuclear area, perimeter, diameter equivalent circle, minimum feret, maximum feret, and circular form factor seemed to be decreased both in the electrical current- and cautery-applied skin samples.The differences between the variables measured in normal skin and in electrical- or cautery-applied skin samples were statistically significant (P < 0.05). However none of the variables showed any meaningful differences between the electrical- and cautery-applied areas.It was concluded that the nuclear changes due to electrical current and thermal injury are identical and morphometric analysis seems not to make any further contributions in the differentiating from each other. Therefore, conventional and more established methods for detection of metallization would be more effective. Language: en |
