Article: Sexualsteroide in der Homöostase des Knochens
[show abstract] [hide abstract]
ABSTRACT: Die Sexualhormone Östradiol und Dihydrotes-tosteron spielen eine herausragende Rolle für die Entwicklung, das Wachstum und die Rege-neration des Knochens. Molekulare Grundlage der Wirkung von Sexualhormonen auf den Knochen ist die Expression spezifischer Rezep -torproteine in Knochenzellen selbst und in Or-ganen, die den Knochen beeinflussen. Neben den klassischen Östrogenrezeptoren (ER) und Androgenrezeptoren (AR) gibt es auch mem-branassoziierte Rezeptoren wie den kürzlich entdeckten G-Protein-gekoppelten Rezeptor 30 (GPR30, GPER), der ebenfalls Östrogene bindet. Sexualhormone sind pleiotrop, direkte und indirekte Auswirkungen von Sexualhormo-nen auf die Knochenhomöostase sind jedoch oft schwer voneinander zu trennen. Zudem können Knochenzellen selbst Sexualhormone aktivieren oder abbauen, indem sie Enzyme des Steroid-Metabolismus exprimieren. Testo -steron ist das Vorläufer steroid für beide Sexual-hormone und kann durch die beiden Schlüssel-enzyme Aromatase und 5α-Reduktase jeweils in Östradiol oder 5α-Dihydrotestosteron um-gewandelt werden. Die vielfältigen Ebenen der Regulation lassen sich für die klinische Praxis so zusammenfassen, dass ihre Hauptwirkung darin besteht, die Anzahl und die Aktivität von Osteoklasten zu regulieren und dieOsteologie/Osteology 01/2010; · 0.16 Impact Factor -
Article: Effect of hyperbaric oxygen therapy on bone prefabrication in rats.
[show abstract] [hide abstract]
ABSTRACT: This experimental study aimed to create a prefabricated vascularized bone graft using the interconnected porous coralline hydroxyapatite ceramic by combining vascular bundle implantation, mesenchymal stem cells, and hyperbaric oxygen therapy (HBOT) administration in a rat model. Forty-five male Sprague-Dawley rats were divided into three groups, each containing 15 rats. The hydroxyapatite ceramics were vascularized by the superficial inferior epigastric artery and vein in all groups. These vessels passed through the hole of the hydroxyapatite blocks. In Group 2, mesenchymal stem cells were administered into the hydroxyapatite. In Group 3, both mesenchymal stem cells and HBOT were administered. The presence and density of any new bone formation and neovascularization were evaluated by radiography, microangiography, scintigraphy, biochemical analysis, and histomorphometry. Neovascularization and bone formation were significantly greater in Group 3, in which both mesenchymal stem cells and HBOT were applied, than the other groups. HBOT enhances neovascularization and osteogenesis, thus HBOT can provide optimal and faster prefabrication of a vascularized bone graft.acta orthopaedica et traumatologica turcica 44(5):403-9. · 0.34 Impact Factor
