Osteoporosis is characterized by bone loss and mobidity with osteoporotic fracture. This study was performed to evaluate the effect of on the bone mass and its related factors in estrogen-deficient animal model. The model rats of osteoporsis showed a significant decrease in bone density, bone ash density, calcium content of femur bone. At the 14th day after ovariectomy-surgery, rats were administered with DBE, extract of Dioscorea batatas, per orally, and continued for 10 weeks. And osteoporosis related parameters were determined to investigate the effect of DBE. Osteoporetic rats showed lower serum estrogen level, higher body weight than normal rats, and showed atrophy of uterine horns. DBE showed inhibitory effect on bone loss in osteoporetic condition, and reduced the increase of ALP activity and osteocalcin level in serum, and reduced the increase of OH-proline level in urine. But, DBE had no effect on cell proliferation and ALP activity in rat calvarial cell culture.
