Abstract: This invention relates to a composition for metabolic bone diseaese and/or bone fractures which comprises a pharmaceutically acceptable carrier and human neurotrophin-3 (NT-3).This invention also relates to a method for the treatment and/or prevention of metabolic bone diseaese or bone fractures which comprises administering to a patient in need of said treatment and/or prevention a medicament containing an effective amount of human neurotrophin-3 (NT-3).

Abstract: A calcitonin originated from the ultimobranchial gland of cartilaginous fishes and having a blood calcium-decreasing activity has the following amino acid sequence: H-Cys-Thr-Ser-Leu-Ser-Thr-Cys-Val-Val-Gly-Lys-Leu-Ser-Gln-Gln-Leu-His-Lys- Leu-Gln-Asn-Ile-Gln-Arg-Thr-Asp-Val-Gly-Ala-Ala-Thr-Pro-NH.sub.2, where the cysteine residues in the peptide may be linked together through a disulfide bond. The novel peptide exhibits an excellent blood calcium-decreasing activity and an excellent chondrocyte differentiation-promoting activity and is useful as a therapeutic agent for hypercalcemia, osteoporosis, Paget's disease, and the like.
