50只健康纯种SD大鼠，喂养22个月，建立老龄大鼠模型，进行股骨、胫骨、腰椎等组织学观察，并评价椎间盘退变的相关指标(椎间盘软骨Ⅱ型和Ⅹ型胶原表达、软骨终板血管芽相对面积、软骨终板钙化层/非钙化层厚度)与骨质疏松的相关指标(骨皮质厚度指数、骨小梁相对面积、骨密度、骨最大应力和应变)的相关性。

Results There was moderate or strong negative correlation among the indexes of the degeneration of intervertebral disc including the relative area of vascular bud, the ratio of the uncalcified and the calcified layer, the quantitation of collagen type Ⅱand the indexes of osteoporosis including the thickness ratio of cortical bone, the relative area of bone trabecula, the density of femoral bone and vertebral body bone, the max stress and straining of bone.

结果 骨质疏松相关指标骨皮质厚度指数、骨小梁相对面积、股骨密度、椎体骨密度与椎间盘退变指标终板血管芽相对面积、非钙化/钙化层比值、Ⅱ型胶原定量之间存在中度到强度的负相关，而与Ⅹ型胶原表达存在中度到强度的正相关，其中椎体骨密度与软骨终板的Ⅹ型胶原相关性最强。
