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