摘要
The development of a nonthrombogenic artificial surface for use with indwelling sensors or catheters remains an elusive goal despite decades of ongoing research. In vivo studies are both labor intensive and costly, and are therefore an inefficient way to rapidly screen possible surface materials. The following in vitro model used glass, polyvinyl chloride (PVC), and polypropylene test tubes incubated with In-labeled rabbit platelets and illustrated that, despite equivalent platelet count and function, platelet adhesion was greatest on glass (n = 13), with PVC (n = 17) at 67 ± 8% and polypropylene (n = 13) at 43 ± 5% when compared with glass. Extrapolating this method by coating test tubes with new, nonthrombogenic materials is a quick and reliable way to screen material before embarking upon more lengthy in vivo animal studies. ©2007Amercian Society of Artificial Internal Organs.
