This paper examines similarities between rhesus macaques and humans in growth and remodeling of the long bones of the extremities. Cross-sectional moments of inertia were measured in three locations of the femur, humerus and tibia of M. mulatta using photon absorptiometry. Differences between males and females were evaluated with respect to age and weight. Remodeling was assessed from histologic sections at the same locations. Sex differences in structural properties of the long bones occur only at mid-diaphysis. Differences reflect the greater need for powerful hindlimb propulsion in males. The growth rate in males is twice as fast as that in females. Several periods of growth acceleration were detected in both males and females. Intracortical remodeling in growing macaques is relatively slow and may be more like that in elderly humans than that in growing children.
本文研究了恒河猴与人类在四肢长骨生长和重塑方面的相似性。使用光子吸收法测量了恒河猴股骨、肱骨和胫骨三个部位的横截面惯性矩。就年龄和体重评估了雄性和雌性之间的差异。从相同部位的组织学切片评估重塑情况。长骨结构特性的性别差异仅出现在骨干中部。这些差异反映了雄性对强大后肢推进力的更大需求。雄性的生长速度是雌性的两倍。在雄性和雌性中均检测到几个生长加速期。生长中的猕猴皮质内重塑相对较慢，可能更类似于老年人而非生长中的儿童。
