摘要： 目的探讨人与狗、猪、牛、羊长骨的哈氏系统的形态特点、图像分析特点及其鉴别要点。方法制作人与狗、猪、牛、羊长骨中段横切磨片35张,光镜下观察比较哈氏系统,并在研究型显微镜下进行图像分析。结果人骨无丛状骨和骨单位带;人与狗、猪、牛、羊骨的哈氏系统在形状、大小、分布位置、均匀程度等方面存在明显差异;人骨哈佛骨板层数最多,哈氏系统直径最大;中央管直径和面积百分比的图像分析结果显示人与动物骨的差异均有显著意义。结论(1)丛状骨、骨单位带在种属鉴定中可作为人骨的排除指标;(2)人骨与狗、猪、牛、羊骨在哈氏系统结构方面有明显区别;(3)利用图像分析进行种属鉴定,中央管面积百分比是区别人骨与动物骨的重要参考指标。

Abstract: Objective To explore the differences in Haversian system between human and animal bones through imaging analysis and morphology description. Methods Thirty-five slices grinding from human being as well as dog, pig, cow and sheep bones were observed to compare their structure, then were analysed with the researchful microscope. Results Plexiform bone or oeston band was not found in human bones; There were significant differences in the shape, size, location, density of Haversian system, between human and animal bones. The amount of Haversian lamella and diameter of central canal in human were the biggest; Significant differences in the central canal diameter and total area percentage between human and animal bones were shown by imaging analysis. Conclusion (1) Plexiform bone and osteon band could be the exclusive index in human bone; (2) There were significant differences in the structure of Haversian system between human and animal bones; (3) The percentage of central canals total area was valuable in species identification through imaging analysis.
