Abstract

Objective : This experiment was designed to investigate the effect of the GYZB hot water extract & ultra-fine powder on the Alzheimer's disease model induced by amyloid β protein (βA). Method : We measured the effects of the GYZB hot water extract on expression of IL-1β, IL-6 mRNA and production of IL-6, TNF-α in the BV2 microglial cell line treated with lipopolysaccharide (LPS). The effects of the GYZB hot water extract & ultra-fine powder on (1) the behavior, (2) expression of IL-1β and TNF-α, (3) glucose in serum, (4) the infarction area of the hippocampus, and brain tissue injury in mice induced with Alzheimer's diseased by βA were investigated. Results : The GYZB hot water extract suppressed the expression of IL-1β and IL-6 mRNA and significantly suppressed the production of IL-6 and TNF-α in the BV2 microglial cell line treated with LPS. The GYZB hot water extract & ultra-fine powder showed a significant inhibitory effect on the memory deficit of 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. The GYZB ultra-fine powder significantly suppressed the expression of IL-1β and TNF-α protein, and the GYZB hot water extract significantly suppressed the expression of TNF-α protein in the microglial cell of mice with Alzheimer's disease induced by βA. The GYZB hot water extract & ultra-fine powder reduced the infarction area of hippocampus in the mice with Alzheimer's disease induced by βA. Conclusions : These results suggest that GYZB hot water extract & ultra-fine powder may be effective for the prevention and treatment of Alzheimer's disease. Investigation into the clinical use of GYZB for Alzheimer's disease is suggested for future research.
