    摘要: An osteoinductive demineralized bone matrix, corresponding osteoimplants, and methods for making the osteoinductive demineralized bone matrix are disclosed. The osteoinductive demineralized bone matrix may be prepared by providing demineralized bone and altering the collagenous structure of the bone. The osteoinductive demineralized bone matrix may also be prepared by providing demineralized bone and compacting the bone, for example via mechanical compaction, grinding into a particulate, or treatment with a chemical. Additives such as growth factors or bioactive agents may be added to the osteoinductive demineralized bone matrix. The osteoinductive demineralized bone matrix may form an osteogenic osteoimplant. The osteoimplant, when implanted in a mammalian body, may induce at the locus of the implant the full developmental cascade of endochondral bone formation including vascularization, mineralization, and bone marrow differentiation. The osteoinductive demineralized bone matrix may also be used as a delivery device to administer bioactive agents.

    摘要: This invention relates to the catalytic hydrogenation of edible oils of animal and vegetable origin. Catalytic hydrogenation according to the invention improves the keeping qualities of such edible oils without impairing their nutritional value or edibility. This is achieved by selectively hydrogenating the triply unsaturated forms of the fatty acids contained in the oil to doubly unsaturated forms using a supported catalyst. The catalyst used contains one or more of the metals Fe, Co, Ni and the platinum group metals and the support may be of extended surface or particulate form, for example, C, stainless steel, ceramics and Fe--Cr--Al--Y alloys.
