Bone mass and bone density were estimated in 219 pedigreed baboons (Papio hamadryas) by radiographic morphometry of the left second metacarpal. Compact bone width (total bone width--medullary canal diameter) and bone ratio (compact bone width/total bone width) decreased with increasing age squared in both sexes. The heritability of medullary canal diameter was 0.64 +/- 0.11, of compact bone width was 0.40 +/- 0.15 and of bone ratio was 0.67 +/- 0.13. The results indicate baboons are a useful model for studies of age, sex and genetic effects on bone mass.
通过对219只纯种狒狒(阿拉伯狒狒)的左第二掌骨进行放射形态测量,估算其骨量和骨密度。在两性中,密质骨宽度(总骨宽度 - 髓腔直径)和骨比率(密质骨宽度/总骨宽度)均随年龄平方的增加而降低。髓腔直径的遗传力为0.64±0.11,密质骨宽度的遗传力为0.40±0.15,骨比率的遗传力为0.67±0.13。结果表明,狒狒是研究年龄、性别和基因对骨量影响的有用模型。
