  • 본 작품은 2014년 11월 초연된 "러시안 알코올"에 움직임을 추가하여 재구성한 작품이다. "러시안 알코올"에서 사용된 소형프로젝트를 활용한 영상작업, 음악리서치, 인터렉션 과정은 삭제하고 기존 작품 영상으로 대체하였다. 본 작품은 장례식에서 접할 수 있는 향들이 망자와의 추억을 잃어가는 과정에 미치는 영향을 설치작품 형식으로 시각화하고 이 향들을 관객이 직접 맡게하여 유사한 기억을 떠올리도록 하였다.

  • With an increase in the number of people suffering from ageing-related diseases in our rapidly aging society, interests in natural products such as maca(Lepidium meyenii), which has properties of enhancing cognition and sexual performance, have increased. This study was conducted to assess the effects of 7 weeks of maca extract supplementation(0.5~2.0 g/kg BW) on scopolamine-induced amnesia in mice and on sperm count in male mice. All doses of maca supplementation significantly protected against scopolamine-induced amnesia as determined by a Morris water maze, but not according to passive avoidance tests. Maca supplementation did not affect acetylcholinesterase activity in the whole brain, nor the testicular sperm count of male mice. This study suggests that maca may have some neuroprotective properties in mice, which will be further examined by future studies.

식물성 열수 추출물 HX106N이 스코폴라민으로 유도한 생쥐 기억력 저하에 미치는 효과에 관한 연구 (Effects of HX106N, a Water-Soluble Botanical Formulation on Scopolamine-Induced Memory Impairment in Mice)

  • HX106N은 용안육, 맥문동, 단삼 및 천마 등의 4가지 식물로 구성된 추출물로서, 선행 연구에서 amyloid ${\beta}$ peptide에 의한 생쥐의 기억력 저하 및 산화 손상을 억제하는 것으로 밝혀졌다. 이 연구에서는 HX106N이 비선택적 무스카린 수용체 길항제로 잘 알려진 스코폴라민(scopolamine)으로 유도한 콜린성 건망증(cholinergic amnesia)에 어떤 영향을 미치는지를 평가하였다. ICR 생쥐에게 스코폴라민(1 mg/kg body weight, i.p.)을 주입하기 1시간 전에 HX106N(100 mg/kg body weight, p.o.)을 투여하였다. 30분 후 수행한 Y-미로 시험(Y-maze test) 및 수동 회피 시험(passive avoidance test)에서 HX106N는 스코폴라민에 의해 감소되는 자발적 변경 행동(spontaneous alternation) 및 지체시간(step-through latency)을 유의미하게 억제하여 건망증을 개선시키는 것으로 나타났다. 또한 HX106N을 투약 1시간 후 생쥐의 해마와 대뇌피질 부위의 아세틸콜린에스테라제(acetylcholinesterase; AChE)의 활성을 측정한 결과 통계적으로 유의미한 정도의 활성 감소가 관찰되었다. 이러한 결과들을 종합할 때 HX106N은 AD에서 관찰되는 콜린성신경전달 장애로 인한 기억력 저하 억제에 사용될 수 있는 가능성을 가진 것으로 판단된다.

  • Glufosinate ammonium (GLA), a phosphinic acid derivate of glutamate, is a broad-spectrum contact herbicide. It structurally resembles glutamate, a typical excitatory amino acid in the central nervous system. In korea, the ingestion of GLA for suicidal attempt or accidental event has increased. The neurological complication of GLA intoxication are characterized by loss of consciousness, convulsion, or memory impairment. But, the exact mechanism of GLA toxicity is yet unknown. This report is about a patient with GLA intoxication who showed anterograde amnesia with selective bilateral hip-pocampal lesions supported GLA intoxication with literature reviews supported.

  • $Capparis$ $zeylanica$ Linn. a 'Rasayana' drug is used for its memory enhancing effects in the traditional Ayurvedic system of medicine. The aim of this study was to evaluate acetylcholinesterase (AChE) inhibitory and memory enhancing activities of $Capparis$ $zeylanica$ Linn. The$in-vitro$ and $ex-vivo$ models of AChE inhibitory activity were used along with Morris water maze test to study the effect on memory in rats. The anticholinesterase effect of methanolic and aqueous extracts of $Capparis$ $zeylanica$ was measured by spectrophotometric Ellman method at 0.1, 0.3, 1.0, 3.0, 10 and 30 mg/ml and brain monoamine oxidase (MAO-A and MAO-B) activity was assessed by Naoi's method. The results $in-vitro$ and $ex-vivo$ AChE assay revealed that methanolic and aqueous extracts of $Capparis$ $zeylanica$ inhibit AChE activity, whereas these extracts did not alter MAO activity at any concentration tested as compared to moclobemide and L-deprenyl. The results indicate that $Capparis$ $zeylanica$ improves scopolamine-induced memory deficits through inhibition of AChE activity, and not by direct MAO inhibition.

  • BASTA is an herbicide which contains glufosinate ammonium as a main component with an anionic surfactant, polyoxyethylene alkylether sulfate, and nonselectively inhibits glutamine synthetase. It became a wildly used herbicide in Korea and its intoxication is now increasing. A 42-year old woman ingested about 300ml of BASTA in a suicide attempt. She showed unconsciousness and respiratory distress in the beginning, and later developed multiple generalized convulsions, low blood pressure, fever and diabetes insipidus. Although she became alert 12 days after the ingestion, she showed retrograde amnesia for a period of about recent 10 years. A neuropsychological test on day 22 revealed frontal lobe dysfunction, visual memory disturbance and slight decrease in visuospatial function. All these neurological abnormalities that might occur due to glufosinate ammonium were almost improved in the follow-up test performed a month later.

  • The aim of this study was to investigate the effects of the water extract of Albizziae Cortex (AC) on the learning and memory impairments. AC was administered to normal mouse and scopolamine-injected amnesia mouse model. Passive avoidance test, Y-maze test, and Morris water maze test were conducted to confirm the cognitive-enhancing activities of AC. Acetylcholinesterase (AChE) activity and acetylcholine (Ach) content were measured after oral administration of AC. On the passive avoidance test, AC (200 mg/kg) significantly increased latency time and recovered scopolamine-impaired learning and memory in mice. In addition, AC (200 mg/kg) reduced Exploration time in target quadrant and reversed the scopolamine-induced cognitive impairments in the Y-maze test. Moreover, AC (200 mg/kg) increased exploration time in target quadrant and improved scopolamine-reduced escape latencies in the Morris water maze test. These effects were presented by regulatory effects of AC on AChE activity and Ach content. Taken together, AC increases cognitive-enhancing activities and ameliorates scopolamine-induced learning and memory impairment. AC might be a potential agent for prevention and treatment of amnesia and dementia.
