the purpose of this study was to evaluate the efficacy of two types of bone substitutes, bio-oss and nuoss, for repair of bone defects.this study was performed on the calvaria of 14 new zealand rabbits. the 6mm critical size defect (csd) models of bone regeneration were used. three csds were created in each surgical site. the first defect was filled with nuoss, the second one with bio-oss and t...

Background: To evaluate the clinical efficiency of treatment dry eye disease (DED) with ocular pain using deproteinized calf blood extract (DCBE) drops as compared to 0.3% sodium hyaluronate (SH) drops.

Various beef tissues such as brain, spleen, heart, kidney, and liver have been shown to be potential sources of antistaphylococcal factors (Nutini and Lynch, J. Exptl. Med. 84:247, 1946; J. Bacteriol. 52:681, 1946; J. Pharmacol. Exptl. Therap. 90:313, 1947; Berger et al., Nature 179:588, 1957). We now wish to report that a similar substance was found in beef blood. Zil'ber and Yakobson (Zh. Mik...

The mechanical properties and microstructure of young and mature bovine femur bone were investigated by optical microscopy and compression testing in the longitudinal and transverse directions for untreated, deproteinized and demineralized cases. Optical microscopy revealed that mature bone has a more established and less porous microstructure compared to young bone. Mature bone was found to be...

The aim of the present work is to purify mucilage polysaccharide extracted from linseed by deproteinization using Trichloroacetic acid (TCA) and Hydochloric (Hcl). 10% w/v TCA deproteinized more than 80% when pH solution was 3. can be considered as an better deproteinizing agent compared hydrochloric evidenced highest efficiency (88.57%)

The mechanical properties of fully demineralized, fully deproteinized and untreated cortical bovine femur bone were investigated by compression testing in three anatomical directions (longitudinal, radial and transverse). The weighted sum of the stress-strain curves of the treated bones was far lower than that of the untreated bone, indicating a strong molecular and/or mechanical interaction be...

fe]lows. 1) By roentgenographie examination, the bone graft density was increasecl quickly in order of deproteinized, frezen, boiled, and fresh graft. 2) By gro$s appearance, the ossal fusion between the graft and the recipient was completed in all deproteinized and frozen grafts and in a few boiled and fresh graft. 3) The bone replacement in graft was not found up to 16 weeks after implantatio...
