猕猴腰椎观察

对7只健康成年猕猴，分别行腰椎影像学，骨性结构测量和椎间盘组织学观察并与人类的有关资料进行比较。为其应用于人类腰椎的动物实验研究提供可靠资料，结果表明，猕猴腰椎间隙高度的变化特点和椎间盘组织学结构特点与人类一致；两者腰椎椎体和椎管的横径，矢径变化非常相似。其脊柱下腰段（腰5-腰7）与人类脊柱下腰段（腰3-腰5）最为接近，两者腰椎的椎体数目，大小，生理弯曲和椎体高度的变化特点存在差异。

Observation of Lumbar Spine on Rhesus Monkey

In order to determine whether the Rhesus monkey is suitable for lumbar spine animal research, 7 adult health Rhesus monkeys were examined with X-ray and MRI. The heights of intervertebral spaces were measured on the X-ray films. The morphologic parameters of the vertebras were measured directly from 5 Rhesus monkeys' lumbar skeleton specimens and the intervertebral discs of 2 lumbar spines were observed histologically. It was showed that the variation features of Rhesus monkey's intervertebral space height and the histological structure of discs were consistent with those of human. The variation features of the vertebral and spine canal's width and depth were similar between the two species. The inferior lumbar regions of two species (L5-7 in Rhesus monkey and L3-5 in human) were most similar. There were, however, substantial differences between the two species on the number, height and size of vertebras as well as the physiological curvature.
