We compared the cytotoxicity of soluble and particulate titanium (Ti), vanadium (V) and nickel (Ni) by biochemical functional analysis and by microscopic morphology with micro-area elemental analysis in vitro using human neutrophils as probes and in vivo in animals. The biochemical analyses of LDH, superoxide anion, TNF-alpha and scanning electron microscopy (SEM) showed that Ni in solution destroys the cell membrane of neutrophils, whereas Ti and V in solution stimulate neutrophils and… CONTINUE READING
