Abstract

We examined blood compatibility and superoxide dismutase (SOD) activity of titania gels yielded on Ti substrate due to the treatment with H₂O₂ solutions. They were correlated to the titania gel surface characteristics. Ti subjected to the chemical treatment with H₂O₂(H₂O₂-Ti) had high blood compatibility or hardly coagulated, and showed higher SOD activity than Ti without the chemical treatment. Ti treated with a hydrogen peroxide containing TaCl₅(H₂O₂/Ta-Ti) had little lower blood compatibility than H₂O₂-Ti, and the SOD activity for H₂O₂/Ta-Ti were lower than that for any other Ti (Ti, H₂O₂-Ti). Thus the decrease in SOD activity for the plasma contacted with H₂O₂/Ta-Ti was in part caused by the Ta ions on the titania gel.
