Abstract
Objective-. To investigate the effects and mechanism of parathyroid hormone (1-34) on lumbar intervertebral disc in ovariectomized rats. Methods-. 3-month-old female Sprague-Dawley rats were randomized into three groups. Ovariectomy was performed in OVX+NS group and OVX+PTH group, and a Sham surgery was performed in the Sham group. Four weeks after ovariectomy,the rats in OVX+PTH group and OVX+NS group received injection subcutaneously of 20 fig/kg PTHd-34) or saline respectively every week. The lumbar vertebra were harvested 20 weeks after ovariectomy and underwent bone mineral density (BMD) measurement, hematoxylin and eosin staining and histochemistry analysis. Results-. The bone mineral density of L2-3 vertebra in the OVX+NS group was significantly lower than that in the Sham group and OVX + PTH group; the histological score of L2-3 vertebra was significantly higher in OVX+NS group than that in the Sham group and OVX+PTH group. There was no significant difference in the immunostaining expressions of collagen I and collagen Ⅱ between the Sham group and OVX+PTH group. Conclusion-. Subcutaneous injection of parathyroid hormone (1-34) (20 μg ? Kg-1 ? Week-1) for twelve weeks can delay the degenerated process of intervertebral discs in ovariectomized rats.关键词
