      The objective was to evaluate the preventive and therapeutic effects of the collagen hydrolysate extracted from Sika deer velvet (CSDV) on osteoporosis rats induced by retinoicacid. Histomorphometric indices and serum biochemical parameters were measured in osteoporosis rats treated with/without antler collagen and in sham-operated rats. Our results were as follows: compared with the osteoporosis group, significant elevation in the levels of bone mineral density (BMD), Ca, P and static histomorphometric indexes and biomechanical properties, but reduction in the level of serum alkaline phosphatase (ALP) were observed in antler collagen-treated groups. However, the above function with the collagenase solution velvet material varied with the different doses.In conclusion, the extracted collagen is found to play a role in the prevention and treatment of osteoporosis rats by retinoic acid.
