Outline of Final Research Achievements

To elucidate the usefulness of the analyzing system using LC/ MS MS, both prospective and retrospective studies were performed. To make sure the usefulness of this analyzing system as the retrospective study, we used the formalin fixed cardiac and nerve samples in amyloidosis patients. The coincidence of this analyzing system to the diagnosed type of amyloidosis was 97%. As the prospective study, undetermined samples of amyloidosis suspected patients. Coincidence of this method and clinical diagnosis was 95%. From those results, this analyzing system was found to be useful method for amyloidosis diagnosis. ③To unknown amyloidosis found in the intestine of aged patients, combination of laser microdisection and LC/ MS MS system was applied. By the analysis, Fibrin3 was identified as the precursor protein of the amyloid. This protein was also found to be the component of amyloid body in the brain.
