1. Objectives Creutzfelt Jacob Disease is one of a group of neurodegenerative disorders causing spongiform encephalopathies due to a infection of prion or unconventional slow virus on central nerve system. The diagnosis of this disease is not easy and there is currently no cure. This article is to report our case about a female patient who was not diagnosed as CJD at the early period so that we treated her with Yangkyuksanhwa-tang(凉膈散火湯) and Jihwangbaekho-tang(地黃白虎湯). 2. Methods Magnetic resonance imaging(brain MRI), blood test and computer tomography were performed. The treatment for this patient was clinically based on Sasang Constitutional Medicine. 3. Results and Conclusions (1) Visual field defect, ataxia, myoclonus, sweating and dysuria were the main symptoms of the patient. (2) The pathological change in parenchyme was not revealed during the early periods by MR imaging. So the diagnosing CJD was not possible during the time in this case. (3) Jihwangbaekho-tang(地黃白虎湯) improved her myoclonus and sweating. Bur her mental disorder and the progress of the pathological change in the parenchyme was not able to be treated.

Recent social interests on mad cow disease and Creutzfelt-Jacob disease lead researcher' focus onto pathogenic prion proteins causing those diseases. The purpose of this study is to introduce a novel method for micromolecular level quantification of PrP 106-126 peptide, which is a part of prion protein. Fluorescamine has been chosen due to its fluorescence emission characteristics upon reaction with primary amines and Alpha-imager is used to detect the intensity of fluorescence. We succeeded in setting optimal conditions for quantification of PrP 106-206, amyloidogenic prion peptide, at micromolecular level. This study will contribute to identify prion protein aggregation inhibitor and develop new prion protein drug.
