Writing in the journal International immunological studies, Rudolf Rebeka of University of Maribor, Slovenia and colleagues there and at the University of Leoben, Austria and the military in Belgrade, Medical Academy, is discussed, like shape memory alloys (SMA) are increasingly used in medical, route cables for catheters, blood vessels, filters and actuators stents-implants.Devices and components thereof can bent and pressed in the destination or ship body, whereupon, then back to its original form, trabajo.Se concerns about the toxicity of the SMA expressed that, nickel or copper, despite the previous tests showing that you are fully biocompatible often contain.
Well, Rudolf and his colleagues have used cells of the immune system, demonstrate human peripheral blood mononuclear cells that made Cobre Alumínio - SMA nickel (CU - al - NI) and Níquel Titanio (NI-TI) do not damage of death of the trigger or the body's cells.
Researchers prepared samples of SMA as thin hilado.A melting tape then PB - cultivated multinationals 20 donors in a solution with a CU - al - NI SMA and saw no significant change in the production of mediators of the immune system called cytokines, 18 of cultures of 20 test.However for two cells from the donor was a strong immune response slightly views released wings like Inflammatory Cytokines, the células.El team suggests that his test the medical profession with a way to quickly and easily could provide a prospective patient to a particular device test biocompatibility.
"" This is the first report, which shows the influence of SMA materials produced by rotation of the fusion technology in human cells, as a thin band", says the team."Use the "use of a simple test." which to identify those individuals to develop an inflammatory response in contact with a bio-materials and so predict should allow unwanted reactions prior to implementation, added
