摘要: Alendronate, a bisphosphonate drug, has shown promise in reducing remodeling and bone loss postmenopausal osteoporosis. Alendronate acts directly on the osteoclast, inhibiting its resorption capability. This inhibition of osteoclast activity led to use bisphosphonates treatment osteogenesis imperfecta condition. Treatment with enhances strength, but consequences linear growth are not well defined. Using oim mouse model for type III imperfecta, two doses alendronate, low (0.125 mg/kg/wk) high (2.5 were administered weekly via intraperitoneal injection starting at 4 weeks age ending 12 assess effects alendronate humerus ulna length. The higher dose reduced length oim/wt wt/wt genotypes both sexes (P 2.5 inhibit long mice through alteration plate possibly chondro-osseous junction.
