Methods: NG108-15 cells were cultured in vitro at 37℃in a humidified atmospherecontaining 5％CO_2. Aβ_(25～35) fragment was dissolved with deionized distilledwater and aged for 4 days at 37℃. The cells were exposured to 5μmol/LAβ_(25～35) for 24h to establish the cell model. Twelve rabbits were divided intotwo groups at random, and garaged with MWD or physiological saline controlrespectively for 7 days to collect two kinds of cerebrospinal fluid, theyare CSF from rabbits treated with MWD and CSF from rabbits treated withphysiological saline.
