ABSTRACT

This study was performed to estimate the corpse age using histological examinations of the fourth and sixth ribs by a morphometric method. One hundred samples of referred bodies of the Legal Medicine Organization of Lorestan province, Iran, were examined. The sampling was performed from the fourth and sixth ribs. The transverse sections of the samples were prepared, in which various variables such as the diameter of the haversian system (DHC), haversian system perimeter (PHS), haversian system area (AHS), and the thickness of the haversian lamellae (TH) were measured using a Motic microscope video system and the Motic Image Plus 2 software. To predict age from sex and the morphometric parameters a stepwise multiple linear regression was used. Accordingly, AHS in rib 4, DHC with lens 10 in rib 4, DHC with lens 10 in rib 6 and TH in rib 6 remained in the model at significance level 0.05 (R square = 0.1654). Although age was associated with some of the studied parameters, the obtained equation was not fit enough to predict the exact age. Further parameters should be studied for prediction of age in corpse.

摘要

这项研究是通过形态测量法使用第四和第六肋骨的组织学检查来估计尸体年龄。对伊朗洛雷斯坦省法律医学组织转介机构的一百个样本进行了检查。从第四和第六肋骨进行取样。制备样品的横截面，其中哈弗系统直径（DHC）、哈弗系统周长（PHS）、哈弗系统面积（AHS）和哈弗板层厚度（TH）等各种变量是使用 Motic 显微镜视频系统和 Motic Image Plus 2 软件测量。为了从性别和形态学参数预测年龄，使用了逐步多元线性回归。因此，在肋 4 中的 AHS，在肋 4 中带有透镜 10 的 DHC，DHC 在肋 6 中具有透镜 10，在肋 6 中具有 TH 在模型中保持在显着性水平 0.05（R 平方 = 0.1654）。尽管年龄与一些研究参数相关，但获得的方程不足以预测确切的年龄。应研究更多参数以预测尸体的年龄。
