By N. S. MIZUNO, V. PEnMAN, F. W. BATES, J. H. SAU’rTER AND M. 0. SCHULrLE SEVERE HYPOPLASIA of the bone marrow,1’2 including any desired degree of thrombocytopenia,3 can be induced in the bovine by feeding of appropriate amounts of trichloroethylene-extracted soybean oil meal ( TCESOM). This affords a unique opportunity for analytic study of thrombocytes from thrombocytopenic animals in which ...

UNLABELLED Several grafting materials have been used in sinus augmentation procedures including autogenous bone, demineralized freeze-dried bone (DFDBA), hydroxyapatite, beta-tricalcium phosphate (beta-TCP), anorganic deproteinized bovine bone and combination of these and others. Up to now a subject of controversy in maxillofacial surgery and dentistry is, what is the most appropriate graft mat...

We isolated cells from both calvaria and the outer cortices of long bones from 3- to 5-mo bovine fetuses. The cells were identified as functional osteoblasts by indirect immunofluorescence using antibodies against three bone-specific, noncollagenous matrix proteins (osteonectin, the bone proteoglycan, and the bone sialoprotein) and against type 1 collagen. In separate experiments, confluent cul...

The present article describes a titanium mesh procedure used for bone augmentation in the treatment of severe maxillary atrophy. A mix of iliac cancellous bone and anorganic bovine bone in a 1:1 ratio is proposed for achieving the best bone quality at the time of implant placement, which is performed 5 to 6 months after the augmentation surgery. This procedure provides for 3-stage surgery using...

New approaches to extracting natural hydroxyl carbonate apatite from bio waste of bovine bones cortical femur have been developed. To extract pure and natural bio ceramics, three different treatments have been applied: 1-Calcination heat treatment at temperature of 700 , 2-alkaline hydrothermal at temperature of 275 and 3-Pressurized low polarity water at temperature of 250 . Raw bovine bone an...

Tocotrienol mixtures have been shown to exert anabolic actions on the skeletal system in animal studies, but it is unclear which tocotrienol isomer shows most prominent effects. This study aims investigate active isomers using hFOB 1.19 human osteoblasts cultured a bovine bone scaffold. The trabecular was sectioned, demineralised and freeze-dried form were scaffolds humidified condition at 37 °...

Trabecular bone has been previously recognized as time-dependent (viscoelastic) material, but the relationships of its viscoelastic behaviour with bone volume fraction (BV/TV) have not been investigated so far. Therefore, the aim of the present study was to quantify the time-dependent viscoelastic behaviour of trabecular bone and relate it to BV/TV. Uniaxial compressive creep experiments were p...

Background. One of the most problematic regions for endosseous implants is the posterior maxilla, not only having poor bone density, but also lacking adequate vertical height as a result of sinus pneumatization. The purpose of the present study was a radiologic, histological, and histomorphometrical evaluation, in humans, of specimens retrieved from sinuses augmented with decellularized bovine ...
