This experiment was designed to investigate the effect of Dichroa febrifuga(DIF) on the Alzheimer’s disease. The effects of DIF extract on $IL-1{\beta}$, IL-6, $TNF-{\alpha}$ mRNA of THP-1 cell treated by $A{\beta}$ plus LPS and amyloid precursor proteins(APP), acetylcholinesterase(AChE), glial fibrillary acidic protein(GFAP) mRNA of PC-12 cell treated by $A{\beta}$ plus $rIL-1{\beta}$ and AChE activity of PC-12 cell lysate treated by $A{\beta}$ plus $rIL-1{\beta}$ and behavior of memory deficit mice induced by scopolamine and mice glucose, uric acid, AChE activity of memory deficit rats induced by scopolamine were investigated, respectively. The results were summarized as follows ; 1. DIF extract suppressed APP, AChE, GFAP mRNA in PC-12 cell treated by $A{\beta}$. 2. DIF extract suppressed $IL-1{\beta}$, IL-6, $TNF-{\alpha}$ mRNA in THP-1 cell treated by LPS. 3. DIF extract suppressed AChE activity in cell lysate of PC-12 cell treated by $A{\beta}$. 4. DIF extract increased glucose, decreased uric acid and AChE significantly in the serum of the memory deficit rats induced by scopolamine. 5. DIF extract group showed significantly inhibitory effect on the memory deficit of mice induced by scopolamine in the experiment of Morris water maze. According to the above results, it is suggested that DIF extract might be usefully applied for prevention and treatment of Alzheimer’s disease and memory deficit.
