Cytotoxicity of experimental casting alloys evaluated by cell culture tests.
The cytotoxicity of a series of 29 experimental alloys and six pure metals was determined with cell culture techniques and succinic dehydrogenase histochemistry. The width of any ring of inhibition, optical density of the histochemically stained cells, and a visual ranking of the intensity of the blue color of the stained cells were compared for determination of cytotoxicity. Twenty-four of the...
متن کاملCasting alloys.
Although the role of dental casting alloys has changed in recent years with the development of improved all-ceramic materials and resin-based composites, alloys will likely continue to be critical assets in the treatment of missing and severely damaged teeth. Alloy shave physical, chemical, and biologic properties that exceed other classes of materials. The selection of the appropriate dental c...
متن کاملThe release of elements of dental casting alloys into cell-culture medium.
Ten dental casting alloys were tested for alloy-element release into cell-culture medium, and this release was related to alloy composition, alloy microstructure, and alloy cytotoxicity (previously determined). Cell-culture medium was analyzed for alloy elements by flame atomic absorption. Concentrations of elements in the medium were normalized by dividing them by their atomic abundance in the...
متن کاملFurther definition by cytotoxicity tests of cell surface antigens of human sarcomas in culture.
Antibodies against cell surface antigens of human sarcomas were detected by a complement-dependent cytotoxicity test. Exogenous rabbit complement was required. Sera were titrated in doubling dilutions to a 50% survival end point, relative to control sera. Test cells were obtained from 21 cell cultures derived from sarcoma specimens, and 9 cultures of non-sarcoma cells. Two lines of evidence ind...
متن کاملContinuous Roll Casting of Aluminium Alloys– Casting Parameters Analysis
The continuous roll casting process (CRC), consisting of continuous strip casting between rolls, is now well known. It was introduced by the SCAL Company (Pechiney Ugine Kuhlmann Group) 60 years ago 1 . The process consists of solidifying aluminum or aluminum alloys between the water-cooled rolls of a duo rolling mill. From the moment when solidification is completed to the moment when the stri...
