Porcine skin has been shown to have similar histological, physiological and immunological properties to human skin and has been suggested as a good analogue for medical and forensic research. This study was undertaken to examine the appearance of bite mark wounds inflicted at known time intervals before and after death. Under general anaesthesia, a series of bite marks were created on a pig's abdomen with a device designed to mechanically produce simulated human bite mark wounds. The pig skin model showed that bite mark characteristics are similar to those found on human skin. This study has provided information on the window of time showing clearly detailed bite marks occurring around the time of death. It also demonstrated that it is possible under certain conditions to determine that a bite mark was made before or after death in a porcine model. Under these experimental conditions, the results suggest that an in-vivo porcine skin model should be considered as a representative model for the study of human bite marks.
猪皮已被证明在组织学、生理学和免疫学特性方面与人类皮肤相似，并被认为是医学和法医研究的良好模拟物。本研究旨在检查在已知的死亡前后时间间隔施加的咬痕伤口的外观。在全身麻醉下，用一种设计用于机械产生模拟人类咬痕伤口的装置在猪的腹部制造一系列咬痕。猪皮模型表明，咬痕特征与人类皮肤上发现的特征相似。这项研究提供了关于死亡时间窗口的信息，清楚地显示了在死亡时间前后出现的详细咬痕。它还表明，在某些条件下，有可能在猪模型中确定咬痕是在死亡之前还是之后形成的。在这些实验条件下，结果表明，体内猪皮模型应被视为研究人类咬痕的代表性模型。
