Calcium Hydroxyapatite Ceramic
Porous blocks of calcium hydroxyapatite ceramic were evaluated as delivery systems for the sustained release of antibiotics. We tested gentamicin sulphate, cefoperazone sodium, and fiomoxef sodium in powder form placed in a cylindrical cavity in calcium hydroxyapatite blocks, using in vitro studies of elution and in vivo studies in rats. Gentamicin sulphate gave a maximum concentration within t...
متن کاملA Novel Fabrication Method for Functionally Graded Materials under Centrifugal Force: The Centrifugal Mixed-Powder Method
One of the fabrication methods for functionally graded materials (FGMs) is a centrifugal solid-particle method, which is an application of the centrifugal casting technique. However, it is the difficult to fabricate FGMs containing nano-particles by the centrifugal solid-particle method. Recently, we proposed a novel fabrication method, which we have named the centrifugal mixed-powder method, b...
متن کاملReverse calcium affinity purification of Fab with calcium derivatized hydroxyapatite.
This study introduces the application of calcium-derivatized hydroxyapatite for purification of Fab. Fab binds to native hydroxyapatite but fails to bind to the calcium derivatized form. IgG, Fc, and most other protein contaminants bind to the calcium form. This supports Fab purification by a simple flow-through method that achieves greater than 95% purity from papain digests and mammalian cell...
متن کاملMolten Salt Synthesis of Calcium Hydroxyapatite Whiskers
Calcium hydroxyapatite (HA) whiskers and crystals were produced by the route of molten salt synthesis. The effects on whisker morphology of chosen flux, flux-to-HA ratio, synthesis temperature, and reaction time were investigated. The thermal stabilities of the produced whiskers were tested at 1300°C in an air atmosphere. A tentative X-ray diffraction pattern was proposed for the HA whiskers. M...
متن کاملInjection pharyngoplasty with calcium hydroxyapatite for treatment of velopalatal insufficiency.
OBJECTIVE To evaluate the efficacy of injectable calcium hydroxylapatite for treatment of velopalatal (VP) insufficiency (VPI). DESIGN Observational case series of 7 patients treated with injectable calcium hydroxylapatite for VPI and followed for 10 to 24 months. SETTING Academic pediatric otolaryngology practice. PATIENTS Seven children aged 6 to 16 years with clinically significant VPI...
