• W2564222018 abstract "본 연구는 칼슘 배합 비율에 따른 초석잠이 scopolamine 치매유도 흰쥐의 기억손상 개선효과에 대하여 연구하였다. 칼슘 배합 비율별(S, 1CS, 5CS군)로 군을 나누어 Y자 미로와 수중미로를 통한 행동실험을 실시한 결과, Y자 미로 실험에서 5CS군이 N군과 비교하였을 때 유사한 수치를 보이며 공간 인지기능을 개선시켰고, 수중미로 실험 또한 CS군의 escape latency가 감소하여 N군과 유사한 수치를 보여 기억력 및 학습능력 개선에 효과적이라는 것을 알 수 있었다. 또한 아세틸콜린 함량과 아세틸콜린에스테라제의 활성을 측정한 결과, CS군은 아세틸콜린에스테라제의 활성을 저해함으로써 뇌 조직 내 신경전달물질인 아세틸콜린의 함량을 증가시켜 뇌 신경세포 활성화 효과를 통해 인지기능 개선 효과를 유도할 수 있을 것으로 사료된다. 해마를 병리조직학적으로 관찰한 결과, 앞선 결과와 유사하게 손상 정도가 심하여 많은 수의 응축된 신경세포가 관찰된 C군에 비하여 CS군은 응축된 신경세포 수가 현저하게 감소하여 신경세포 손상을 억제한 것으로 보인다. 따라서 칼슘 배합 비율에 따른 초석잠은 scopolamine 치매유도 흰쥐모델에서 기억력, 학습능력 및 인지능력 개선에 효과적으로 작용하는 천연물 유래 기능성 소재로 이용될 수 있을 것으로 사료된다. The aim of this study was to investigate the anti-amnesic effect of Stachys sieboldii MIQ. according to the mixing ratio of calcium on scopolamine-induced learning and memory impairment, in vivo. At the end of the adaptation period, SD rats were divided into a normal group (N), a control group (C: scopolamine), a positive control group (PC: scopolamine + tacrine), and a sample group (S: scopolamine + Stachys sieboldii MIQ., 1CS: scopolamine + low calcium-mixed Stachys sieboldii MIQ., 5CS: scopolamine + high calcium-mixed Stachys sieboldii MIQ.), and were tested with learning and memory tests. The C and CS groups were found to have a decreased scopolamine-induced memory deficit in the Y-maze and water maze tests. Brain tissue analysis showed that the CS group decreased acetylcholinesterase (AChE) activity and increased acetylcholine (Ach) content, both of which are indicative of neuronal cell activity. From a light microscopy study, the nucleus of neurons in the hippocampus of the brain was more shrunken or condensed in the C group compared to the CS group. In the CS group, the damage to the neurons in the hippocampus of the brain was suppressed. These results suggest that Stachys sieboldii MIQ. according to the mixing ratio of calcium provides a significant anti-amnesic effect against scopolamine-induced cholinergic system deficits and cognitive impairment." @default.
