【摘要】 目的探讨丛状骨和骨单位带的种属特征及其法医学应用价值。方法人及猪、牛、羊、狗长骨中段横切磨片35张,在光学显微镜下观察骨组织中丛状骨和骨单位带的形态学特征。结果丛状骨和骨单位带在猪、牛、羊、狗的密质骨中广泛存在,人骨组织中几乎不见;同种动物不同个体之间骨组织学结构也存在差异。结论观察丛状骨和骨单位带是根据人骨鉴别种属的重要排除指标。更多还原

【Abstract】 Objective To explore the applicability of the histological features of plexiform bone and osteon banding to species identification. Methods 35 ground cross sections of the tibial midshaft collected from 10 human cadavers, 10 pigs, 5 cattle, 5 dogs, and 5 sheep, were observed under light microscope at 100-fold magnification. Results Plexiform bone and osteon banding were mostly observed in nonhuman bones, whereas rarely in human bones. Additionally, histological structures also varied with different individuals within a species. Conclusion The plexiform bone and osteon banding are the two important characteristics for certifying nonhuman bone in species identification.更多还原
