title: [Effect of kidney deficiency caused by ovariectomy on serum osteocalcin level and tumor necrosis factor in mice with collagen induced arthritis].
abstract: OBJECTIVE
  To explore the effect of ovariectomy caused Kidney Deficiency on the metabolism of bone in mice with collagen induced arthritis.
  
  
  METHODS
  The mice for experiment were immunized with subcutaneous injection of type II collagen to induce arthritis after ovariectomy. Severity of joint swelling, radioimmunoassay of serum estradiol (E2), osteocalcin (OC) and tumor necrosis factor (TNF), and pathological changes of joint, including changes on synovia, articular cartilage and bone, were observed once weekly.
  
  
  RESULTS
  The E2 level of ovariectomized mice dropped down obviously, while the contents of OC and TNF increased significantly. Severe pathological changes can be seen in synovial tissues, cartilage and bone.
  
  
  CONCLUSIONS
  Kidney Deficiency caused by ovariectomy exacerbated the pathological changes of collagen-induced arthritis in mice.
