Abstract
Abstract PCT No. PCT/SE89/00015 Sec. 371 Date Sep. 19, 1989 Sec. 102(e) Date Sep. 19, 1989 PCT Filed Jan. 19, 1989 PCT Pub. No. WO89/06548 PCT Pub. Date Jul. 27, 1989.The reaction product of H2O2 and metallic titanium, a titanium peroxy radical gel, exhibits oxidizing and anti-inflammatory effects and is used, for instance, as a biocompatible oxidant, an anti-inflammatory agent or in vitro coating of an implant body. The gel-like product is produced by treating metallic titanium with H2O2.
