であると思われる。BACKGROUND ART Senile dementia including Alzheimer's disease is a disease showing progressive memory and cognitive impairment. In these diseases, the cholinergic nervous system, which projects from the basal forebrain to the cerebral cortex and hippocampus, has a prominent disorder, which is choline acetyltransferase (hereinafter, abbreviated as “ChAT”) that is an acetylcholine synthase activity. Therefore, it is considered that a drug that activates ChAT activity is effective as a therapeutic drug for senile dementia including Alzheimer's disease.

The cells were dispersed mechanically (pipetting). About 5 x 10 of the obtained isolated cells were placed on a 48-well plate in which astroglial cells were grown on a sheet in advance.
The cells were seeded at 5 cells / cm 2 and cultured in DF medium containing 5% quasi-fetal bovine serum and 5% non-immobilized bovine serum (equivalent mixture of Dulbecco's modified Eagle medium and Ham's F12 medium). Astroglial cells were prepared from the cerebral cortex of rat embryo E20, propagated for several generations, and then used. The day after the start of culture, the test compound was replaced with the same medium containing a predetermined concentration,
After culturing for 1 week, the cells were diluted with 0.1% Triton X.
