    Sammanfattning : 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

    Författare :Eva Bornefalk; Uppsala universitet; []
    Nyckelord :Medical sciences; bone; cytokines; osteoporosis; cAMP; IL-1; IL-6; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : 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. LÄS MER

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

    Författare :Monica Gordh; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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;

    Sammanfattning : 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.

  5. 5. Kinins : important regulators in inflammation induced bone resorption

    Författare :Anna Bernhold Brechter; Ulf Lerner; Hans-Erik Claesson; Umeå universitet; []
    Nyckelord :Bone resorption; Osteoblasts; Kinins; B1 and B2 receptors; IL-1β; TNF-α; Prostaglandin; COX-2; RANKL; Transcription factors; IL-4; IL-13; Medical Cell Biology; medicinsk cellbiologi;

    Sammanfattning : 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. LÄS MER
