목적 및 방법 : 본 연구에서는 한의학에서 전통적으로 신경보호 약물로 사용되어온 총명탕 물 추출물의 급성 독성증상을 관찰하기 위하여 한국식품의약품안전청 고시 제 2009-116호에 따라 암수 ICR마우스 단회 경구투여 독성 실험을 실시하였다. 반수치사량, 개략적치사량, 표적장기 등을 관찰하기 위하여, 수율 9.70% 총명탕 물 추출물 2,000, 1,000 및 500 mg/kg을 암수 마우스에 단회 경구 투여하고, 투여 후 14일 동안의 임상증상, 사망례, 체중 및 증체량의 변화 및 부검소견을 관찰하였으며, 투여 14일 후 14개 주요 실질 장기에 대한 중량 및 조직병리학적 관찰을 실시하였다. 또한 별도의 암수 매체 대조군을 두어 그 결과를 비교하였다. 결 과 : 본 실험의 결과, 설치류 최대 한계투여 용량인 2,000 mg/kg까지 총명탕 물 추출물 투여와 관련된 사망례가 인정되지 않았으며, 암수 매체 대조군을 포함하여, 모든 실험군에 걸쳐 산발적으로 관찰된 일부 우발적인 육안부검 및 조직병리학적 소견을 제외하고, 총명탕 물 추출물 투여와 관련된 임상증상, 체중 및 장기 중량의 변화, 14개 주요장기에 대한 육안부검 및 조직병리학적 소견이 인정되지 않았다. 결 론 : 따라서 마우스 단회 경구투여 독성실험에서 총명탕 물 추출물의 반수치사량 및 개략적 치사량은 각각 설치류 투여 한계용량인 2,000 mg/kg 이상으로 관찰되어, 매우 안전한 약물로 판단되며, 임상사용에는 별 다른 문제를 일으키지는 않을 것으로 판단된다.

Objective : This research aims to investigates the effects of CMT and HCMT on Dementia. and we also want to know the different effect of CMT, HCMT by drug types. Methods : The research is progressed by two types of experiment. one experiment is BV2 microglial cell line treated by LPS in vitro and another experiment is memory deficit mice induced by scopolamine in vivo. Results : The CMT and HCMT is effective in BV2 microglial cell line treated by LPS in vitro and in the serum of the memory deficit mice induced by scopolamine in vivo. But, there is no significant difference between CMT and HCMT extract&nano powder in experimental conclusion. Conclusions : These results suggest that the two drug types of CMT and HCMT may be effective for the prevention and treatment of Dementia. Investigation into the further study two drug types of the CMT and HCMT for Dementia is suggested for future research.

This experiment was designed to investigate the effect of the ODTCMT and DDTCMT extract on protecting microglia and inhibiting acetylcholinesterase and oxidants. The effects of the ODTCMT and DDTCMT extract on cell death of BV2 microglial cell line treated by $IFN-{\gamma}$ ; expression of NO, ROS in BV2 microglial cell line treated by lipopolysaccharide (LPS) ; AChE activity in PC-12 cell treated by NGF were investigated, respectively. The ODTCMT and DDTCMT extract significantly increased cell viability in BV2 microglial cell line treated with $IFN-\nu$. The ODTCMT and DDTCMT extract suppressed the NO and RDS production in BV2 microglial cell line treated by LPS. The ODTCMT and DDTCMT extract groups also showed inhibition of AChE activity in PC-12 cell line. According to the above result, it is suggested that the ODTCMT and DDTCMT extract might be usefully applied for prevention and treatment of Alzheimer's disease.

Objectives : This study was designed to signpost the study of brain, intelligence and memory, while interpreting the concept of 'Chongmyeong(聰明)' neotrically and linking it to the clinic of Korean medicine. Methods : In this paper, the meaning of the word 'Chongmyeong(聰明)' is divided into two parts, intelligence and memory. We also explored the relationship between brain science and 'Chongmyeong(聰明)' based on complex system theory, cognitive science and embodied cognition. Results : Through the process of refining the concept of 'Chongmyeong(聰明)' neoterically, we proposed the new method to understand the concept of 'Chongmyeong(聰明)'. Conclusions : The concept of 'Chongmyeong(聰明)' should be interpreted not as a reductionistic viewpoint of brain science but as a viewpoint of brain science based on visual and auditory system and complex system. Human cognition is physically embodied in the environment, from the viewpoint of embodied cognition that it is constituted and formed in an interactive context with society and culture connected with the environment.

With tablets and powder, decoction has been a widely-used method of medicine formula. However, for these formulas have unique bitter tastes and flavors of herbal component materials as it is, the compliance of herbal medicine is severly decreased especially for female and younger patients. Consequently, expected treatment effects can't be acquired completely. If loathsome tastes and flavors of decoction were effectively reduced while pharmacological activity were kept intact, the compliance could be promoted Chong-Myung-Tang has been widely prescribed for student patients with memory This study shows that Chong-Myung-Tang+chocolate have no difference from Chong-Myung-Tang in terms of pharmacological activity. Sensory difference with net chocolate was also surved. In order to observe the difference of Chong-Myung-Tang+chocolate and Chong-Myung-Tang, memory impairment was induced by intraventricular injection of $A{\beta}_{25-35}$ peptides on mice and Chong-Myung-Tang and Chong-Myung-Tang+chocolate were administered orally for 14 days. In water maze task, improvement of learning ability during acquisition period and significant increase of memory score during retention period resulted from the treatment of Chong-Myung-Tang and Chong-Myung-Tang+chocolate with respect to the $A{\beta}-injected$ control animals. Furthermore, the $A{\beta}_{25-35}$ toxicity on the hippocampus was assessed with immunohistochemistry (Bax, TUNEL), and differences in antioxidant activity was observed through TBARS and DPPH test. We employed sensory tests using chocolate flavor, herb flavor, and bitter taste & hardness as standards to show sensory differences with net chocolate. In this study, it is demonstrated that Chong-Myung-Tang+chocolate do not disturb the pharmacological activity of Chong-Myung-Tang, and have no sensory difference with net chocolate. Chong-Myung-Tang+chocolate can be used to enhance the compliance remarkably and thought of as an effective, functional formula to maximize expected treatment.

We investigated whether an aqueous extract of Chong-Myung-Tang inhibits secretion of tumor necrosis $factor-{\alpha}$ $(TNF-{\alpha})$ from primary cultures of mouse astrocytes. Chong-Myung-Tang dosedependently inhibited the $TNF-{\alpha}$ secretion by astrocytes stimulated with substance P (SP) and lipopolysaccharide (LPS). Interleukin-1 (IL-1) has been shown to elevate $TNF-{\alpha}$ secretion from LPS-stimulated astrocytes while having no effect on astrocytes in the absence of LPS. We therefore investigated whether IL-1 mediated inhibition of $TNF-{\alpha}$ secretion from astrocytes by Chong-Myung-Tang. Treatment of Chong-Myung-Tang to astrocytes stimulated with both LPS and SP decreased IL-1 secretion. Moreover, incubation of astrocytes with IL-1 antibody abolished the synergistic cooperative effect of LPS and SP. These results suggest that Chong-Myung-Tang may inhibits $TNF-{\alpha}$ secretion by inhibiting IL-1 secretion and that Chong-Myung-Tang has a antiinflammatory activity in the central nervous system.
