Objectives : This experiment was designed to investigate the effect of the Hwanso-dan hot water extract & ultra-fine powder on microglia and memory deficit model Methods : The effects of the Hwanso-dan hot water extract on expression of IL-l${\beta}$, IL-6, TNF-${\alpha}$ mRNA and production of IL-l${\beta}$, IL-6, TNF-${\alpha}$ in BV2 microglial cell line treated by lipopolysacchaide were investigated. The effects of the Hwanso-dan hot water extract & ultra-fine powder on the behavior of the memory deficit mice induced by scopolamine and uric acid & AChE in serum of the memory deficit mice induced by scopolamine were investigated. Results : 1. The Hwanso-dan hot water extract suppressed the expression of IL-l${\beta}$, IL-6, TNF-${\alpha}$ mRNA in BV2 microglial cell line treated by lipopolysacchaide. 2. The Hwanso-dan hot water extract suppressed the production of IL-l${\beta}$, IL-6, TNF-${\alpha}$ in BV2 microglial cell line. 3. The Hwanso-dan hot water extract & ultra-fine powder decreased uric acid and AChE significantly in the serum of the memory deficit mice induced by scopolamine. 4. The Hwanso-dan hot water extract & ultra-fine powder groups showed significantly inhibitory effect on the scopolamine${\sim}$induced impairment of memory in the experiment of Morris water maze. Conclusions : This experiment shows that the Hwanso-dan hot water extract & ultra-fine powder might be effective for the prevention and treatment of Memory deficit disease. Investigation into the clinical use of the Hwanso-dan hot water extract & ultra-fine powder for Alzheimer's disease is suggested for future research.
