| Research Abstract |
A simple pretreatment method for the determination of 24S-hydroxycholesterol as a surrogate marker of Alzheimer disease in human plasma and human cerebrospinal fluid by gas chromatography/mass spectrometry (GC/MS) has been developed. It was found a tendency that the concentration levels of 24S-hydroxycholesterol and amyroid・in plasma with Lewy patients have been decreased. Futhermore, we investigate 24S-hydroxycholesterol-mediated cytotoxicity for SH-SY5Y cells, and also explore the anti-cytotoxicity agents. We found the polyphenols from Japanese tea have an anti-cytotoxicitic effect.
