Bacterial culture of eluent from Ti

Bacterial culture of eluent from Ti nanotubes inrabbits. TNT nanotube implantation produces a great num-ber of bacteria, whereas Ag/TNT nanotubes produce fewerbacterial cultures (Figure 7). With S-Ag/TNT treatment, pos-itive bacterial cultures are few and almost absent.Histology of Ti nanotubes from rabbits. Bone trabeculaeare loose around TNT nanotubes at postoperative week 4,with bone destruction [Figure 8(A)]; no complete fibrouscalluses are formed. A large number of inflammatory cellsare visible in the medullary cavity, and a large amount ofpolynuclear phagocytes are visible on high magnification[Figure 8(E)]. Neither Ag/TNT nor S-Ag/TNT implantsshows inflammation, and a large number of fibrous bonecalluses or new bones are formed around the implant [Fig-ure 8(B-D)]. Also, the bone interface integration is good,and cartilage cells proliferation are active around the boneinterface on high magnification [Figure 8(F)]; the surround-ing material generates abundant collagen.DISCUSSIONSIn general, super-hydrophobic coating can be prepared bytwo methods: constructing or modifying an appropriate dualmicro/ nanostructure on the material with low surface energy.The second method is always adopted for preparing a super-hydrophobic surface for metallic orthopaedic implants.
