This research investigates the effect of the Crataegus pinnatifida BGE. var. major N.E. BR(CPVM) on Alzheimer's disease. The CPVM extract suppressed the expression of IL-1 β, IL-6, APP, AChE mRNA in PC-12 cells treated with CT105. The CPVM extract suppressed the AChE activity, and the production of APP significantly in PC-12 cells treated with CT105. The CPVM extract group showed a significant inhibitory effect on the memory deficit for the mice with Alzheimer's disease induced by CT105 in the Morris water maze experiment. The CPVM extract suppressed the over-expression of IL-1 β, TNF- α and ROS in the mice with Alzheimer's disease induced by CT105. This study suggests that CPVM may be effective for the prevention and treatment of Alzheimer's disease.

This research investigates the effect of the Crataegus pinnatifida BGE. var. major N.E. BR(CPVM) on Alzheimer's disease. Specifically, the effects of the DYHT extract on (1) $IL-1{\beta}$, IL-6, amyloid precursor proteins(APP), acetylcholinesterase(AChE), and glial fibrillary acidic protein(GFAP) mRNA of PC-12 cells treated with CTI05; (2) the AChE activity and the APP production of PC-12 cell treated with CT105; (3) the behavior; and (4) expression of $IL-1{\beta}$, $TNF-{\alpha}$, reactive oxygen species(ROS), nitrite oxide(NO); and (5) the infarction area of the hippocampus, and brain tissue injury in Alzheimer's diseased mice induced with CT105 were investigated. The results are as follow. 1. The CPVM extract suppressed the expression of $IL-1{\beta}$, IL-6, APP, AChE, and GFAP mRNA in PC-12 cells treated with CT105. 2. The CPVM extract suppressed the AChE activity and the production of APP significantly in PC-12 cells treated with CT105. 3. The CPVM extract group showed a significant inhibitory effect on the memory deficit for the mice with Alzheimer's disease induced by CT105 in the Morris water maze experiment. 4. The CPVM extract suppressed the over-expression of $IL-1{\beta}$, $TNF-{\alpha}$, ROS and NO in the mice with Alzheimer's disease induced by CT105. 5. The CPVM extract reduced the infarction area of hippocampus, and controlled the injury of brain tissue in the mice with Alzheimer's disease induced by CT105. These results suggest that the CPVM extract may be effective for the prevention and treatment of Alzheimer's disease.
