人类骨组织特征研究

为解决杀人毁尸案中骨骼残片的法医鉴定问题,对人类不同部位的骨骼进行组织学研究,为比较骨骼残片是否为人类骨骼提供科学基础。本研究提取的人类骨骼有颅骨、四肢长骨。将提取的骨片制成骨组织片,在显微镜下观察,并将观察结果输入计算机进行分析。通过对人类不同部位骨骼的组织学特征研究,描述了人类骨组织的板层结构、骨单位及骨小管的形态。本研究结果在法医学、人类学及考古学等领域有一定的应用价值。

The Study of Bone Histology in the Human Skeleton

To assess species affiliation of bone fragments by examining histological characters using a sample of two male skeletons (skulls and long bones only) aged 20 years and 30 years. The human sample was collected from forensic autopsies. Bone was cut into 2mm histological section plates, which were then observed at 10 ×20 power with an Olympus, HB-20 microscope. Different parts of the human skeleton showed a variety of bone histological characters and different parts of the same bone (for example, the upper and lower sections of a long bone) showed various microscopic structures. The outer and inner circumferential lamellae, interstitial lamellae, osteons, and bone lacuna were observed on different parts of the bone. Histological characters of compact bone and spongy bone were described, and with this qualitative data entered into the computer. Photomicrographs were also taken. This study has demonstrated a new method for bone fragment identification in forensic anthropology, which is also useful to studies in anthropology and archaeology.
