  • 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.

  • 최근 고령화 사회가 지속됨에 따라, 치매(Dementia)에 대한 관심이 높아지고 있다. 그 중에서 알츠하이머병(Alzheimer's disease)는 전체 치매 환자의 50~60%로 가장 많은 비율을 차지하는 퇴행성 뇌질환으로, 현재 의료계에선 알츠하이머병에 대한 명확한 예방법 및 치료법에 대해 내놓지 못하고 있으며, 치매 발병 전 조기 치료 및 조기 예방법에 대한 중요성이 강조되고 있다. 본 논문에서는 정상인과 알츠하이머병에 걸린 환자의 MRI 데이터셋을 활용하여 컨볼루션 신경망을 중심으로 여러 가지 활성화 함수를 접목시켜, 가장 효율적인 활성화 함수를 찾고자 한다. 또한 알츠하이머 치매분류 모델링을 통해 향후 의료분야에 적합한 치매 구분 모델링으로 활용하고자 한다.

  • 우리나라의 노인 대상으로 식생활지침 실천도 점수에 따른 치매 유병률의 차이를 분석한 결과, 치매 노인군이 정상노인군에 비해 나이가 유의하게 많았고, 성, 체격, 그리고, 식사속도, 식사를 거르는 횟수, 편식 등 식생활 특성에는 정상 노인군과 유의한 차이가 없었다. 식생활지침 세부 실천지침 중에서 다양한 식품군 섭취, 규칙적이고 안전한 식사, 음주, 가벼운 운동부분에서 치매노인군의 실천도가 정상노인군에 비해 낮았고, 그 외의 문항에서는 유의한 차이가 없었다. 식생활지침 실천도 점수가 높을수록 치매 유병률이 낮은 경향을 보였다. 요약하면 어르신을 위한 식생활지침의 실천도가 높을수록 알츠하이머형 치매의 위험이 감소하므로, "어르신을 위한 식생활지침 (보건복지부, 2011)" 실천도를 높이는 것이 알츠하이머형 치매 예방에 도움이 될 수 있으며, 향후 알츠하이머형 치매 예방을 위한 식생활 지침의 기초자료로 활용할 수 있을 것으로 사료된다.

  • Transcranial magnetic stimulation (TMS) is a safe and noninvasive tool for investigating the cortical excitability of the human brain and the neurophysiological functions of GABAergic, glutamatergic, and cholinergic neural circuits. Neurophysiological biomarkers based on TMS parameters can provide information on the pathophysiology of dementia, and be used to diagnose Alzheimer's disease and differentiate different types of dementia. This review introduces the basic principles of TMS, TMS devices and stimulating paradigms, several neurophysiological measurements, and the clinical implications of TMS for Alzheimer's disease.

  • Sphingolipids are ubiquitous building blocks of eukaryotic cell membranes that function as signaling molecules for regulating a diverse range of cellular processes, including cell proliferation, growth, survival, immune-cell trafficking, vascular and epithelial integrity, and inflammation. Recently, several studies have highlighted the pivotal role of sphingolipids in neuroinflammatory regulation. Sphingolipids have multiple functions, including induction of the expression of various inflammatory mediators and regulation of neuroinflammation by directly effecting the cells of the central nervous system. Accumulating evidence points to sphingolipid engagement in neuroinflammatory disorders, including Alzheimer's and Parkinson's diseases. Abnormal sphingolipid alterations, which involves an increase in ceramide and a decrease in sphingosine kinase, are observed during neuroinflammatory disease. These trends are observed early during disease development, and thus highlight the potential of sphingolipids as a new therapeutic and diagnostic target for neuroinflammatory diseases.
