  1. 1. Bone Healing after implantation of bone substitute materials. Experimental studies in estrogen deficiency

    University dissertation from Umeå universitet

    Author : Sven Öberg; Umeå universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Bone grafts; hydroxyapatite; estrogen deficiency; demineralised bone; bone formation; AAA bone; bone defect; titanium implants; resonance frequency analysis.; Kirurgi; MEDICINE Surgery; MEDICIN Kirurgi; kirurgi; Surgery;

    Abstract : Bone formation and bone healing were studied in the mandible, tibia and skull bones in adult, healthy and estrogen deficient rabbits implanted with different bone substitutes.In the first study an evaluation of the differences in bone regeneration in and around solid (Alveograf *) and porous hydroxyapatite (Interpore 200*) was undertaken.

  2. 2. Cytokines and bone : On the role of IL-1 and IL-6 in bone metabolism

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Eva Bornefalk; Uppsala universitet.; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; bone; cytokines; osteoporosis; cAMP; IL-1; IL-6; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Abstract : Cytokines such as interleukin-1 (IL-l) and interleukin-6 (IL-6) have been implicated in the pathogenesis of postmenopausal osteoporosis. The regulation of cytokine release is unclear, and the mechanism of cytokine induced bone resorption remains to be elucidated. READ MORE

  3. 3. Survival of onlay bone grafts. A study in the adult rat

    University dissertation from Department of Oral Surgery and Oral Medicine, Faculty of Odontology, Carl Gustafs väg 34, SE-214 21 Malmö, Sweden

    Author : Monica Gordh; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; polytetrafluoroethylene; artificial; membrane; immunohistochemistry; cortical perforations; bone morphogenetic protein; bone marrow; bone; bone grafts; Odontologi; stomatology; Odontology; skull; tibia;

    Abstract : The aim of this thesis was to study onlay bone grafting in the adult rat to improve graft incorporation and perservation of graft size. In 167 adult isogeneic lewis rats, the size maintenance and bone formation at the graft-host interface of uni- and bicortical onlays positioned in various environments and treatments were investigated.

  4. 4. Kinins important regulators in inflammation induced bone resorption

    University dissertation from Umeå : Odontologi

    Author : Anna Bernhold Brechter; Umeå universitet.; [2006]
    Keywords : Bone resorption; Osteoblasts; Kinins; B1 and B2 receptors; IL-1β; TNF-α; Prostaglandin; COX-2; RANKL; Transcription factors; IL-4; IL-13; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Inflammatory processes in, or in close vicinity of, the skeleton often lead to loss of bone tissue. Different cytokines have been shown to be involved as stimulators of inflammatory induced osteoclastic bone resorption. READ MORE

  5. 5. The neuropeptide VIP and the IL-6 family of cytokines in bone effects on bone resorption, cytokine expression and receptor signalling in osteoblasts and bone marrow stromal cells

    University dissertation from Umeå : Odontologi

    Author : Emma Persson; Umeå universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; osteoblast; bone resorption; cytokines; IL-6; neuropeptides; VIP; transcription factor; NATURAL SCIENCES Biology Cell and molecular biology Cell biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Cellbiologi;

    Abstract : Bone tissue is continuously degraded and rebuilt to respond to the needs of the body. Cells of the osteoblast lineage are responsible for the formation of bone, whereas the resorption of bone tissue is carried out by osteoclasts. READ MORE
