Objective: This research investigates the effect of the Jangwon-Dan,(JWD) on Alzheimer’s disease.
Method: The effects of the JWN extract on (1) $IL-1{\beta}$, IL-6, and $TNF-{\alpha}$ mRNA of PC-12 cells treated with LPS; (2) amyloid precursor proteins(APP), acetylcholinesterase(AChE), and glial fibrillary acidic protein(GFAP) mRNA, the AChE activity and the APP production of PC-12 cell treated with CT-105; (3) the behavior; (4) expression of $IL-1{\beta}$, $TNF-{\alpha}$, MDA, $IL-1{\beta}$ mRNA, and $TNF-{\alpha}$ mRNA, (5) the infarction area of the hippocampus, and brain tissue injury in Alzheimer’s diseased mice induced with ${\beta}A$ were investigated.
Result: 1. The JWN extract suppressed the expression of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ mRNA in THP-1 cells treated with LPS. 2. The JWN extract suppressed the expression of APP, AChE, and GFAP mRNA in PC-12 cells treated with CT-105. 3. The JWN extract suppressed the AChE activity, and the production of APP significantly in PC-12 cells treated with CT-105. 4. For the JWN extract group a significant inhibitory effect on the memory deficit was shown for the mice with Alzheimer’s disease induced by ${\beta}A$ in the Morris water maze experiment, which measured stop-through latency, and distance movement-through latency. 5. The JWN extract suppressed the over-expression of $IL-1{\beta}$ protein, $TNF-{\alpha}$ protein, MDA, $IL-1{\beta}$ mRNA, $TNF-{\alpha}$ mRNA, and CD68/GFAP, in the mice with Alzheimer’s disease induced by ${\beta}A$. 6. The JWN extract reduced the infarction area of hippocampus, and controlled the injury of brain tissue in the mice with Alzheimer’s disease induced by ${\beta}A$.
Conclusion:These results suggest that the JWN extract may be effective for the prevention and treatment of Alzheimer’s disease. Investigation into the clinical use of the JWN extract for Alzheimer’s disease is suggested for future research.
