BACKGROUND:Bisphosphonates that can increase bone density and inhibit bone resorption have been clinical y confirmed, but the structure of the bone matrix has been less studied.
OBJECTIVE:To observe the effects of alendronate on bone structure and bone matrix metabolism, and then to investigate the control ing mechanism by which alendronate improves bone mass and increase bone intensity.
METHODS:An ovariectomized rat model was prepared and intervened with alendronate as treatment group. Model and sham-surgery groups were set as controls. Alendronate effects on bone mineral density, bone metabolism, bone biomechanics, and bone structure were observed in bone loss rats using bone imaging, bone tissue pathology and biomechanical test and enzyme-linked immunosorbent assay.
RESULTS AND CONCLUSION:Alendronate intervention could fight against bone loss as compared with model group at weeks 4, 8, and 12 after treatment (P<0.05). Compared with the model group, the expression of urinary deoxypyridinoline and serum carboxyterminal propeptide of type Ⅰ procol agen was decreased significantly after alendronate intervention (P<0.05);the maximal load, maximal pressure and modelus on the lumbar vertebrae and femur were increased as wel as ratio of urinary pyridinoline/deoxypyridinoline of type Ⅰ procol agen (P<0.05). These findings suggest that alendronate intervention can inhibit bone loss in rats induced by estrogen deficiency, increase biomechanical properties, improve bone matrix structure, and meanwhile, recover the Ⅰ col agen crosslinking component due to ovariectomy.

Objective To investigate the role of cyclooxygenases (COXs) in the up-regulation of the expression of P2X3 receptors in the dorsal root ganglion (DRG) in rats with neuropsthic pain. Methods Twenty-four male SD rats, weighing 250-280 g, were randomly divided into 4 groups ( n = 6 each): sham operation group (group S), chronic constrictive injury (CCI) group, COX-1 inhibitor ibuprofen group (group Ⅰ), and COX-2 inhibitor celecoxib group (group C). Neuropathic pain was induced by CCI. The animals were anesthetized with intraperitoneal 10% chloral hydrate 300-500 mg/kg. CCI was produced by placing 4 ligatures on the left sciatic nerve at 1 mm intervals. In group S, the left sciatic nerve was only exposed but not ligated. In groups Ⅰ and C, ibuprofen 40 mg·kg-1 ·d-1 and celecoxib 30 mg·kg-1 ·d-1 were given through a gastric tube into the stomach at day 3-14 after operation respectively. Paw withdrawal latency (PWL) and paw withdrawal threshold (PWT) were measured before operation (baseline), and at 3, 5, 7, 10 and 14 days after operation. Then the rats were sacrificed and their L()-6 DRGs were removed to detect the expression of P2X3 mRNA and protein. Results Compared with group S, PWL was significantly shortened, PWT decreased, and P2X3 mRNA and protein expression up-regulated in group CCI ( P < 0.05=. Compared with group CCI, PWL was significantly prolonged, PWT increased, and P2X3 mRNA and protein expression down-regulated in groups Ⅰ and C (P <0.05=. Compared with group Ⅰ, PWL was significantly prolonged, PWT increased, and P2X3 mRNA and protein expression up-regulated in group C ( P <0.05=. Conclusion COXs are involved in the up-regulation of the expression of P2X3 receptors in the DRG in rats with neuropathic pain, and the effect of COX-1 is stronger than that of COX-2.
