Electronic cigarettes are novel tobacco products that are frequently used these days. The cartridge contains liquid nicotine and accidental poisoning, even with a small oral dose, endangers children. We present here a mortality case of a 15-month-old child who ingested liquid nicotine mistaking it for cold medicine. When the emergency medical technicians arrived, she was found to have pulseless electrical activity. Spontaneous circulation was restored after approximately 40 minutes of cardiopulmonary resuscitation. The cotinine level in her urine was 1,716 ng/mL. Despite intensive supportive care, severe anoxic brain injury was found on computed tomography and the child ultimately died. This fatality highlights the need for public health efforts to minimize such accidents.

The purpose of this study was to investigate how student felt the strengths and shortness of presentation methods for formation of interior spaces. For this study, the process of the interior architecture design class was divided into three stages: the programming. the design development, and the design completion. In the design development stage, students used presentation methods: hand sketch, scale model, computer modeling, and virtual realty. The strengths of hand sketch was that quick expression. Models provided three-dimensional feelings. Computer modelling provide realistic color and texture. Virtual reality provided three-dimensional immersion and real scale. It is effective that students collect brain storm images using quick hand sketch in the beginning of design development stage. After that, they compose interior spaces in study models with small scale. Watching the models, they design details of spaces by using hand sketch and computer modelling. Using virtual reality, they can check the scale and circulation. Finally, they complete computer modelling by texture mapping and check the final design in virtual reality.

Metabolites, such as isopropyl alcohol (IPA) produced by rumen fermentation, were intravenously infused into a jugular vein of goats during feeding to explore the mechanism and roles of IPA in ruminating behavior (number of boli and ruminating time). Three female goats were confined in metabolism cages with a stanchion, The ruminating behavior measured by the number of ruminations, ruminating time, number of remastications, and remasticating time decreased (p<0,05) with intravenous IPA infusion. The IPA concentrations and VFA concentrations increased in the blood circulation. Our data suggest that sensitive receptors of rumination to IPA are more likely to be in an area such as the brain stem where they can respond to blood metabolite levels.

Aerobic exercise affects cerebral circulation, action of neurotransmitters, glucose, oxygen, and energetic substances and influence on the central nervous system for cognition. This study suggests that both the intensity of exercise and the level of cognitive task need to be considered. Computerized neurobehavioral testing is a more effective method, compared to conventional methods, of neuropsychological testing when measuring cognition objectively, in cases that we found. The intensity of 80% max HR had effect on more complex tasks such as 3 Digit Addition and Digit Span Backward, and the intensity of 65% max HR had an effect on more simple tasks such as Color Word Vigilance and Digit Span Forward. We can assume that different intensity of aerobic exercise might involve specific areas of the brain as they could have different sensitivities, so further studies measuring regional cerebral blood flow or electroencephalogram are needed to confirm the results.

Headache is symptom of many people suffered. It caused simply by fatigue, stress, but it also caused by inflammation, mechanical or chemical stimulus, circulation disorder, brain damage. Modern societies develop rapidly by traffic system. But lately it suffering with many traffic problem. Traffic accident is most important of many traffic problem. We experienced a 35 year-old female who complained headache, caused by a traffic accident that happened 22 month ago. We treated the patient by the way of Eo-hyeol (瘀血) type of headache with Herbal medication and Acupuncture. After being treated, the patient show that symptoms(headache, insomnia, anorexia) was improved considerably. This result suggests that oriental medicine treatment has good effect on headache due to traffic accident.

We will present various MR findings of hyperacute ischemic stroke with our own experiences in the management of the patients according to the findings. 대상 및 방법： A total of 441 patients were underwent 'acute stroke MR' imaging protocol between Mar. 2001 and Jun. 2003. The protocol included initial T2-weighted image (WI), diffusion WI (DWI, b=2000), time-of-flight (TOF) MR angiography (MRA), and pefusion WI(PWI), and follow-up T2WI, DWI, TOF MRA, and neck vessel contrast-enhanced MRA obtained three to five days after the insult. Among them, we retrospectively reviewed the MR findings and clinical courses of 193 patients with anterior circulation territorial infarction. Those ICA and MCA lesions were divided into six and five groups respectively according to the level and mechanism of the occlusion. PWI findings can be another factor in the management planning.

담음(痰飮)은 질병(疾病)의 경과중에 발생되는 병리적(病理的)인 산물(産物)로, 담음(痰飮) 자체가 질병(疾病)의 원인(原因)이 될 수 있으며, 질병(疾病)의 결과물로 생길수도 있다. 저자는 <내경(內經)> 이후의 역대(歷代) 문헌(文獻) 고찰(考察)을 통해 담음(痰飮)이 중풍(中風)의 발생에 미치는 영향과, 아울러 담음(痰飮)과 진액(津液)의 관계, 진액(津液)과 뇌(腦)의 관계, 담음(痰飮)과 어혈(瘀血)의 관계 등을 연구하였다. 담음(痰飮)은 칠정(七情)의 부조(不調), 정기휴손(精氣虧損), 음식실조(飮食失調), 외감육음(外感六淫), 체질적(體質的) 소인(素因)등의 인자(因子)로 인해 발생되어 열담(熱痰), 풍담(風痰), 습담(濕痰)으로 화(化)하고 장부(臟腑) 경락(經絡)에 울체(鬱滯)하여 기혈(氣血)의 순환을 막아 중풍(中風)을 유발하게 된다. 한편 담음(痰飮)은 진액(津液)으로부터 형성되고, 진액(津液)은 기체(氣滯), 화울(火鬱), 한응(寒凝)의 병리과정(病理過程)을 통하여 담음(痰飮)으로 전화(轉化)되며, 뇌(腦)는 진액(津液)의 자윤(滋潤)과 충양(充養)에 의해 그 기능을 유지한다. 따라서 진액(津液)이 담음(痰飮)으로 전화(轉化)되어 기혈운행(氣血運行)을 막으면 뇌(腦)에도 영향을 미칠 수 있을 것으로 사료된다. 담음(痰飮)과 어혈(瘀血)의 관계를 보면 담음(痰飮)은 어혈(瘀血)과 병리변화(病理變化)에 있어 밀접한 관계에 있으며, 중풍발생(中風發生)에 있어서 담음(痰飮)이 어혈(瘀血)에 선행(先行)하거나, 어혈(瘀血)이 먼저 형성된 후에 담음(痰飮)이 형성되거나, 혹은 서로 겸(兼)하여 발생할 수도 있다.

Objective : To clarify the benefits and therapeutic effects of intra-arterial papaverine infusion on the symptomatic cerebral vasospasm, we analyzed the results of treatment in 32 patients retrospectively. Methods : A total of 510 patients underwent surgical clipping or endovascular intra-aneurysmal treatment for ruptured intracranial aneurysm between May, 1996 and June, 1999. The delayed ischemic deficit(DID) was developed in 90 of 510 patients. Of these 90 patients, 32 developed symptomatic vasospasm inspite of using modest "3H therapy". The brain CT scan was taken before the intra-arterial infusion of papaverine. The 32 patients underwent 42 intra-arterial papaverine infusion. The symptomatic vasospasm was divided into three groups : deterioration of mental status(Group 1), appearance of a focal neurologic deficit(Group 2), or both(Group 3). We measured Glasgow Coma Scale(GCS), arterial diameters, and cerebral circulation time(CCT) at the time of pre- and postangioplasty. Results : The number of patients in group 1, 2 and 3 were 26, 7, 9 respectively. Eighteen cases showed improvement of GCS more than 2 scores, 16 more than 1, and 8 showed no change of GCS. Average cerebral circulation time(CCT) was decreased ranging from 0.0%-67.5%, and arterial diameters were increased in 21 cases ranging from 1 to 4 folds. Conclusion : Intra-arterial papaverine infusion seemed to have therapeutic effects on symptomatic vasospasm by improving the neurological signs and increasing the arterial diameter. We suggest that intra-arterial papaverine infusion would be an useful adjunctive therapeutic modality in symptomatic vasospasm.

Objective : The treatment of complex intracranial aneurysms remains challenging. One approach is the application of surgical flow alteration to treat aneurysms that are neither clippable, trappable, or coilable. The efficacy and limitations of surgical flow alteration have not yet been established. Methods : Cases of complex aneurysms treated with surgical flow alteration (proximal occlusion with or without bypass, distal occlusion with or without bypass and bypass only) were included in this retrospective study. Results : Among a total of 16 cases, there were 7 giant aneurysms (${\geq}25mm$ diameter) and 9 large aneurysms (>10 mm diameter); 15 of 16 aneurysms were unruptured. There were 8 aneurysms located in the anterior circulation, while the other 8 were in the posterior circulation. Aneurysms were treated with proximal occlusion in 10 cases and distal occlusion in 5 cases; in 1 case, the aneurysm occluded spontaneously after bypass without parent artery occlusion. All but 2 cases underwent prior or concurrent bypass surgery. Complete obliteration of the aneurysm at the latest imaging follow-up was shown in 12 of 16 cases (75.0%). Bypass patency was confirmed in 13 of 15 cases (86.7%). Surgery-related morbidity developed in 3 cases (18.8%, Glasgow outcome scale of 4) and all were perforator infarctions. There were no mortalities. Conclusion : Surgical flow alteration resulted in a high rate of aneurysmal obliteration with acceptable morbidity. Although several limitations remained, it could represent an alternative method for treating complex aneurysms.
