Ossein
Definition:
(n.) The organic basis of bone tissue; the residue after removal of the mineral matters from bone by dilute acid; in embryonic tissue, the substance in which the mineral salts are deposited to form bone; -- called also ostein. Chemically it is the same as collagen.
Example Sentences:
(1) The 'Ossein' implants remained as inert material neither invaded by host cells nor inducing any bone formation.
(2) A study was undertaken in 60 adult rabbits in order to determine the effects of ossein-hydroxyapatite compound on bone healing.
(3) The present study was undertaken, therefore, to examine whether oral administration of ossein-hydroxyapatite compound (OHC) could stimulate new bone growth on aluminium oxide implant surfaces and, if so, whether it was the mineral or organic part of the compound which was responsible.
(4) Study was undertaken to identify polypeptide factors in the commercially available ossein-mineral-compound and to see if they are present in a biologically relevant quantity.
(5) Ossein-hydroxyapatite compound (OHC) is a protein-mineral complex derived from bovine bone.
