Abstract

Radiation synovectomy is an useful alternative treatment to rheumatoid arthritis and Re$\^$188/ is suggested as an ideal radiopharmaceutical agents because beta ray (2.1 MeV) emitted from Re$\^$188/ is appropriate for synovial cell ablation and gamma ray (155 KeV) is ideal for dosimetry. Its' ideal particle size (2-5 mm) was achieved by conjugation with tin-colloid, In this study, we investigated the toxicity, stability and biodistribution to evaluate the suitability of DA-7911 as a synovectomy agent.
