Abstract: Provided is a method for screening a composition for preventing or treating an osteoporosis and a metabolic bone disease using a TALLYHO/JngJ mouse, and more particularly, to a method for screening a compound effective in preventing and treating a disease caused by abnormalities of a bone metabolism including an osteoporosis, through assessment of a bone regeneration activity, such as acceleration of osteoblast differentiation, inhibition of osteoclast differentiation, variation of cytokine in a serum, as well as a bone mineral density and a bone mineral content in a femur, using a TALLYHO/JngJ mouse instead of a ovariectomized animal generally used in estimating the efficacy of a new osteoporosis medicine in an animal. The screening method has a simple and stable experiment procedure, and can be used in developing an agent for treating an osteoporosis of men and improving the bone mineral content.
