This study was conducted to investigate the effect of herbs on memory improvement by focusing on their cholinergic functions in Tg2576 mice. Seven herbs were used to obtain extracts by using alcohol and water. In screening test for cholinergic activities of the extracts, acetylcholinesterase (AChE) ...

Tg2576 형질전환 마우스는 무엇으로 잘 알려져 있는가? | 본 연구에서는 치매모델동물로서 잘 알려진 Tg2576 형질전환 마우스를 사용하였다. Tg2576 마우스와 Wild type (Wt) 마우스(B6SJLF/J, 12주령, 20±5 g)는 각각 Taconic Farms (Germantown, NY, USA)와 (주)코아텍(Geonggido Peongtaek, Korea)으로부터 구매하였으며, 12시간 간격으로 조명을 주고, 온도 22±2°C , 습도 50-55%의 환경에서 식이와 물은 자유롭게 섭취할 수 있게 하였다. | |
아세틸콜린분해효소의 역할은? | 아세틸콜린분해효소는 말초신경과 중추신경계의 대표적 신경전달물질인 아세틸콜린을 분해하는 효소로, 활성을 억제해 뇌 속의 아세틸콜린 농도를 증가시키는 방법이 알츠하이머질환 환자 치료에 이용되고 있다(34). 따라서 본 실험에서는 모든 식물의 알코올과 열수 추출물들이 아세틸콜린분해효소 활성에 미치는 효과를 나타내었다(Table 1). | |
수동회피시험을 사용하여 Tg2576 형질전환 마우스에서 미나리 알코올추출물이 인지능 개선에 미치는 영향을 측정한 대조군의 실험 결과는? | 1과 같다. 대조군에서 머무름 시간이 생리식염수를 투여한 대조군(Wt-CTL) 202.70초, 미나리추출물을 투여한 대조군(Wt-OJAE) 196.71초로 통계적으로 유의적인 차이는 없었다. 그러나 실험그룹 중 생리식염수를 투여한 실험군(Tg-CTL)은 머무름 시간이 61. |
