Studies on the mechanisms of tumorigenesis induced by polyetherurethane in rats: production of superoxide, tumor necrosis factor, and interleukin 1 from macrophages cultured on different polyetherurethanes.
J. Biomed. Mater. Res. 49(1) , 99-105, (2000) Interaction of macrophages (Mos) with polyetherurethane (PEU) was investigated to clarify the role of the Mos in the early stage of tumorigenesis of PEUs. As for the inflammatory cytokines produced from Mos, the amount of tumor necrosis factor (TNF) produced ... |
