AIM: The aim of the present study is to investigate changes of five biochemical markers of bone turnover during the formation of ovariectomized rat model. METHODS: Three-month-old female SD rats were divided randomly into ovariectomized (OVX) group, sham-operated (sham) group and control group. Five biochemical markers of bone turnover levels, including serum osteocalcin (OC), total alkaline phosphatase (ALP), bone-specific alkaline phosphatase (BALP), tartrate-resistant acid phosphatase (TRAP) and hydroxyproline (HYP) were measured before and at 1, 1.5, 2, 2.5, 3 and 4 months after surgery. The right proximal tibias of rats were excised at the same time point for histopathological observation. RESULTS: Serum OC, ALP, BALP, TRAP and HYP levels in OVX group were significantly higher than that in sham group. As regard to the time of peak level arrived, the sequence of changes was as follows: TRAP/HYP→OC→ALP/BALP. There was a significant positive correlation between five markers. The pathological changes of trabecular bone in OVX group were only observed 3 months after surgery. CONCLUSION: The results suggest that postmenopausal osteoporosis has a high bone turnover rate. During the formation of ovariectomized rat model, changes of bone resorption markers precede changes of bone formation markers. Serum OC, ALP, BALP, TRAP and HYP are sensitive to evaluate the bone loss in the earlier stage of postmenopausal osteoporosis.
