  • Objectives : This study was performed to find a desirable way for acupuncture treatment of Alzheimer Disease. Methods : The authors reviewed several literatures about 'Alzheimer Disease' and 'Dementia'. Based on the review, we interpreted the causes and symptoms on viewpoint of three yin and three yang, and also researched desirable way for acupuncture treatment of Alzheimer Disease. Results and Conclusions : The symptoms of Alzheimer Disease belong to the unbalance between reverting yin and lesser yang. The factors affecting attack rate of Alzheimer Disease are also related with the unbalance between reverting yin and lesser yang. It is necessary to inhibit the function of reverting yin and to activate the function of lesser yang for the acupuncture treatment of Alzheimer Disease.

  • The amyloid hypothesis has been considered a major explanation of the pathogenesis of Alzheimer disease. However, failure of phase III clinical trials with anti-amyloid-beta monoclonal antibodies reveals the need for other therapeutic approaches to treat Alzheimer disease. Compared to its relatively short history, optogenetics has developed considerably. The expression of microbial opsins in cells using genetic engineering allows specific control of cell signals or molecules. The application of optogenetics to Alzheimer disease research or clinical approaches is increasing. When applied with gamma entrainment, optogenetic neuromodulation can improve Alzheimer disease symptoms. Although safety problems exist with optogenetics such as the use of viral vectors, this technique has great potential for use in Alzheimer disease. In this paper, we review the historical applications of optogenetic neuromodulation with gamma entrainment to investigate the mechanisms involved in Alzheimer disease and potential therapeutic strategies.

  • This research investigated the effect of the Chaenomelis fructus(CMF) on Alzheimer's disease. The effects of the CMF extract on the behavior in the Morris water maze experiment; the expression of IL-1β, TNF-α, ROS on the microglial cell; IL-1β mRNA, TNF-α mRNA, CD68/GFAP and MDA on the brain tissue; the infarction area of the hippocampus, and brain tissue injury in the mice with Alzheimer's disease induced by βA were investigated. The CMF extract group showed a significant inhibitory effect on the memory deficit on the mice with Alzheimer's disease induced by βA in the Morris water maze experiment. The CMF extract group suppressed the over-expression of IL-1β, TNF-α, IL-1β and TNF-α mRNA, ROS, MDA, CD68/GFAP in the mice with Alzheimer's disease induced by βA. The CMF extract reduced the infarction area of hippocampus, and controlled the injury of brain tissue in the mice with Alzheimer's disease induced by [3A. This study suggest that CMF may be effective for the prevention and treatment of Alzheimer's disease.

  • The paper describes a new instrument for early detection of Alzheimer's disease. A new instrument for early detection of Alzheimer's disease is constructed on both the questionnaire for the investigation of living environment, and the lists for the functional tests of the sense, the physiology, and the left and right brains. When the medical doctor has made a diagnosis of Alzheimer's disease, the demented patient does not recover the indication adding available treatments. Then, the indication of a patient only takes a turn for the worse. For the demented patient can be kept his/her life style, Alzheimer's disease can make an early detection using a new instrument before a diagnosis of the dementia. And the indication of a demented patient can be delayed by the available medical treatments.

  • Several lines of evidence have revealed that phosphorylation of amyloid precursor protein (APP) at Thr668 is involved in the pathogenesis of Alzheimer's disease (AD). Okadaic acid (OA), a protein phosphatase-2A inhibitor, has been used in AD research models to increase tau phosphorylation and induce neuronal death. We previously showed that OA increased levels of APP and induced accumulation of APP in axonal swellings. In this study, we found that in OA-treated neurons, phosphorylation of APP at Thr668 increased and accumulated in axonal swellings by c-jun N-terminal kinase (JNK), and not by Cdk5 or ERK/MAPK. These results suggest that JNK may be one of therapeutic targets for the treatment of AD.
