1-Alpha-OH-cholecalciferol (1-alpha-OH-D3) and optimal calcium intake in calcium deficiency osteoporosis mediated by parathyroid activity morphologic and biochemical changes in adult male rats. 1985

T S Lindholm, and O S Nilsson, and T C Lindholm

By feeding adult male rats a calcium deficient diet for a period of 6 weeks osteoporosis can be induced with respect to significant changes in mass, turnover, chemical composition, and morphology of bone and parathyroid glands. When subsequently treating the osteoporotic rats with a combination of 1-alpha-OH-cholecalciferol (1-alpha-OH-D3) and optimal calcium intake osteoporosis as well as morphologic changes of parathyroids can be almost totally reversed as soon as after 2 weeks and completely after 4 and 6 weeks. Notwithstanding the change to an optimal calcium intake seems to be more important in normalizing the osteoporotic skeleton resulting from calcium deficiency than is the ingestion of 1-alpha-OH-D3, which may per se induce new bone formation.

D002118 Calcium A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
