摘　　要：探讨人类密质骨的年龄变化规律 ,为法医学、人类学利用骨骼推断年龄提供新方法。收集 6 7例中国北方汉族女性右侧第六肋骨的中 1/3段 ,制作脱钙骨切片 ,在计算机图像分析仪上测量 9项组织形态学参数 ,并进行多元逐步回归分析 ,得到一个推断年龄的多元回归方程 :^Y =31 2 6 4+0 86 8X2 +2 86 6 93X4 +0 6 89X7-778 874X8-0 0 0 6X9,复相关系数和标准误分别是 0 92 3和 4 0 8。经 2 5例已知年龄的标本检验 ,预测年龄的误差在± 5岁以内的可达 84% ,误差在± 8岁以内的可达 10 0 %。结果表明The purpose of this paper is to study the pattern of change which are age associated,so as to provide a new method of age estimation by bone for forensic medicine and anthropology.The middle one third of right ribs were collected from 67 Chinese females living in North China.Decalcified cross section slides were histomorphometrically examined by using an image analyzer.Then the parameters were subjected to multiple stepwise regression analysis to produce an equation:=31 264+0 868X 2+286 693X 4+0 689 X 7-778 874X 8-0 006X 9.The multiple correlation coefficient and standard error of estimate were 0 923 and 4 08,respectively.When the formula was checked by 25 specimens,84% of the estimated ages fall within ±5 years of actual ages,and 100% of the estimated ages fall within ±8 years of actual ages.This showed that female ages could be deter mined by the histomorphometry of ribs.
