This research investigates the effect of the Hibiscus syriacus(HSS) on Alzheimer's disease.
Specifically, the effects of the HSS extract on (1) IL-1β, IL-6, and TNF-α mRNA of PC-12 cells treated with LPS; (2) amyloid precursor proteins(APP), acetylcholinesterase(AChE), and glial fibrillary acidic protein(GFAP) mRNA of PC-12 cells treated with CT-105; (3) the AChE activity and the APP production of PC-12 cell treated with CT-105; (4) the behavior; (4) expression of IL-1β, TNF-α, IL-1β mRNA, TNF-α mRNA, and reactive oxygen species(ROS); (5) the infarction area of the hippocampus, and brain tissue injury in Alzheimer's diseased mice induced with βA were investigated.
The results were summarized below ;
1. The HSS extract suppressed the expression of IL-1β, IL-6 and TNF-α mRNA in THP-1 cells treated with LPS.
2. The HSS extract suppressed the expression of APP, AChE, and GFAP mRNA in PC-12 cells treated with CT-105.
3. The HSS extract suppressed the AChE activity, and the production of APP significantly in PC-12 cells treated with CT-105.
4. For the HSS extract group a significant inhibitory effect on the memory deficit was shown for the mice with Alzheimer's disease induced by βA in the Morris water maze experiment, which measured stop-through latency, and distance movement-through latency.
5. The HSS extract suppressed the over-expression of IL-1β, TNF-α, IL-1β and TNF-α mRNA, CD68/GFAP, ROS in the mice with Alzheimer's disease induced by βA.
6. The HSS extract reduced the infarction area of hippocampus, and controlled the injury of brain tissue in the mice with Alzheimer's disease induced by βA.
These results suggest that the HSS extract may be effective for the prevention and treatment of Alzheimer's disease. Investigation into the clinical use of the HSS extract for Alzheimer's disease is suggested for future research
