Objectives: Uwhangchungsim-won(UC) has been used in the treatment of a wide variety of conditions including stroke, hypertension, arterosclerosis, autonomic imbalance, and mental instability, in Korean traditional hospitals. The aim of this study was to evaluate the effect of DC on cerebral hemodynamics and to determine the appropriate dosage. Methods: We studied changes in hyperventilation-induced cerebrovascular reactivity and mean blood flow velocity of the middle cerebral arteries(MCAs) were studied by means of transcranial Doppler ultrasound. Changes in mean blood pressure, pulse rate and expiratory CO2(PECO2) were observed using Cardiocap TM/5. Six healthy young volunteers who were administrated with full doses of DC for group A, and half doses for group B. Six other healthy subjects comprised the control group. The evaluation was performed during basal condition, and repeated at 20, 40, 60, 120, and 180 minutes after administration. Results: Increases of cerebrovascular reactivity and mean blood flow velocity in the middle cerebral artery in group A were significantly different compared with group B and the control group (p<0.1). Mean blood pressure, pulse rate and expiratory CO2 did not change during the observation and were not different among these three groups. We observed that in cerebrovascular reactivity induced hyperventilation, group A was most effective at 40 minutes after administration, and its effectiveness lasted for 120 minutes. Conclusions: This study provides evidence for UC, in full doses, as an agent for dilation of the cerebral arteriols to increase hyperventilation-induced cerebrovascular reactivity as a consequence of faster recovery of blood flow velocity.

Cervicofacial subcutaneous emphysema rarely occurs after tonsillectomy. However, it can occur after disruption of the oral or pharyngeal mucosa during tonsillar dissection. When subcutaneous emphysema happens, broad spectrum antibiotics and conservative management are employed to prevent deep neck infection. In case of upper oropharyngeal disruption, the possibility that food may spread to the damaged legion is low. Therefore, it would be recovered by short term fasting without deep neck infection. We report a recent case of iatrogenic cervicofacial subcutaneous emphysema after tonsillectomy experienced as well as relevant document review.
윤상필 한국인터넷윤리학회 2017 The Digital Ethics(디지털 윤리) Vol.1 No.1
In the Age of Intelligent Information, we must protect core values from all social mechanisms that alienate human dignity, freedom, and personality. Essential norms to protect them are ultimately ethics, and ethics is based on voluntary compliance, so it is not meaningful unless the members themselves sympathize and keep them together. The way to establish these norms is not far away, but it can be derived from the democracy that forms the basis of the state in the real space. It is necessary to implement the reflux system reflecting the will of the people in a more diverse and systematic way in cyberspace. Based on this consciousness, users who are active in cyberspace should be able to act with ethical consciousness that can respect each other autonomously and subjectively from the viewpoint of community, and be responsible for it. When all the members of the cyber space join together and try to resolve the issue of ethical consciousness, such as self-regulatory efforts of the market and companies, and the ethical awareness of users themselves, our community can be a leading example of the world.

Objectives: This study aimed to investigate the seasonal variation in stroke types, ischemic stroke subtypes, stroke risk factors and Sasang constitutions. Methods: 226 patients with acute stroke within 14 days onset were included, who were admitted to Kyunghee Oriental Medical Center from November 2005 to October 2006. The year was subdivided into four parts: spring (March-May); summer (June-August); fall (September-November); and winter (December-February). Stroke types, ischemic stroke subtypes, stroke risk factors and Sasang constitutions in the four groups were examined. Results: Ischemic stroke was most frequent in summer, whereas hemorrhagic stroke was most frequent in winter. There was no significant difference in seasonal variation of stroke. The frequency of ischemic heart disease among stroke risk factors was significantly high in spring (p=0.031). The frequency of hypertension, diabetes mellitus, atrial fibrillation, and hyperlipidemia did not differ among seasons. There was no significant difference in Sasang constitution among seasons. Frequency of small vessel occlusion was highest in summer. Large artery atherosclerosis was frequent in spring and summer,but seasonal variation of ischemic stroke subtypes did not show statistical difference. Conclusion: Acute stroke demonstrates seasonal characteristics according to stroke types, ischemic stroke subtypes, risk factors for stroke, and Sasang constitutions. These results have important clinical implications in stroke prevention.

본 연구는 정화되지 않은 생활하수 유입과 활발한 어패류 해상 양식으로 유기물 오염이 국지적으로 심화되고 있는 가막만에서 다모류군집의 구조적 특성과 서식처 교란 정도에 따른 변화 양상을 파악하기 위하여 수행되었다. 현장조사는 1999년 9월과 2000년 2월에 실시되었고 퇴적물의 입도, 유기물 함량, 산휘발성황화물, 용존산소 등을 포함한 저서환경과 대형저서다모류군집에 대한 조사가 이루어졌다. 1999년 하계 조사에서 북서내만역과 국동항 인근정점의 표층퇴적물내 유기물 함량은 만의 중부나 입구역에 비해 최대 3배 가까이 높았다. 특히 해수 소통이 원활하지 않은 북서내만역의 저서환경은 빈산소 수괴 형성과 황화물의 고농도 발생에 의해 극도로 악화된 상태였다. 2000년 동계 조사에서 북서내만역의 용존산소농도는 정상적으로 회복된 상태였지만 표층퇴적물 내에는 여전히 많은 양의 유기물과 황화물이 존재하였다. 하계에 조사된 28개 정점 가운데 북서내만역의 5개 정점에서는 생물이 전혀 출현하지 않았으며 이를 제외한 23개 정점에서 총 119종의 다모류가 평균 900 $ind./m^2$의 밀도로 출현하였다. 전반적으로 종수는 만의 입구와 중앙부에서 높았고 개체 밀도는 유기물 함량이 상대적으로 높은 국동항 인근과 만 입구의 가두리 양식장 근처에서 높았다. 하계 밀도 분포를 좌우한 우점종은 잠재적 유기물 오염 지표종인 Aphelochaeta monilaris와 Lumbrineris longifolia 등이었다. 동계에 조사된 북서내만역과 만 중부의 12개 정점에서는 총 81종의 다모류가 채집되었고 평균 개체 밀도는 2,802 $ind./m^2$로 하계에 비해 다소 증가한 양상이었다. 하계에 무생물구역이었던 정점들은 선소에 인접한 정점을 중심으로 Capitella capitata, Pseudopolydora paucibranchiata와 Dipolydora socialis 등에 의해 우점되고 있었으며 만의 중상부와 중앙부에서는 Euchone alicaudata와 Praxillella affinis 등이 우점하였다. 하계와 동계 다모류군집 각각에 대한 다차원척도법(MDS) 분석 결과, 두 계절 모두 채집 정점의 지형학적 위치에 따라 그룹이 형성되었다. 그러나 이러한 그룹의 형성은 퇴적물 특성과 같은 자연적 요소보다는 빈산소수괴의 발생과 소멸, 유기물 함량의 상대적 농도 분포와 같은 교란적 요소의 차이가 반영된 결과로서 인위적 교란의 정도가 가막만 전체에 분포하는 다모류군집의 구조적 특성을 결정하는데 중요한 역할을 하고 있음을 암시하였다. This study was carried out to investigate spatio-temporal variations of benthic environment and macrobenthic polychaete communities in Gamak Bay where excessive organic matters from untreated sewage effluents and fish and shellfish farming activities have been accumulated in certain regions. Such environmental variables as sediment composition, organic content, acid volatile sulfide and dissolved oxygen content etc. were measured and polychaete specimens were taken in September 1999 and February 2000. In September 1999, organic contents were up to three times higher in the northwestern part of the bay and the area closed to Gukdong harbor than in the rest of the bay. In particular, benthic environment of the northwestern part of the bay was extremely deteriorated by the occurrence of hypoxia and highly concentrated sulfide. Of 28 stations investigated in summer, 5 stations located in the northwestern part were azoic. In the rest of the stations, a total of 119 polychaete species were sampled with a mean density of 900 $ind./m^2$. While species richness was higher in the entrance and central part of the bay where water exchanges with open sea were relatively active, density was higher in the moderately enriched stations neighbouring Gukdong harbor and fish farms where such potential indicators of organic pollution as Aphelochaeta monilaris, Lumbrineris longifolia were largely dominant. In February 2000, a total of 81 polychaete species appeared with a mean density of 2,802 $ind./m^2$ from 12 stations sampled in winter. Azoic areas were recolonized by Capitella capitata, Pseudopolydora paucibranchiata and Dipolydora socialis which showed maximum density in the innermost station. On the other hand, the rest of the stations were dominated by Euchone alicaudata and Praxillella affinis. The configuration of the stations sampled in summer and winter on the multidimensional scaling plots reflected the position of each stations within the bay in which there were great differences in organic content, sulfide concentration and oxygen content rather than in sediment composition. Therefore, heterogeneities in polychaete community structure in Gamak Bay were primarily influenced by the degree of the disturbance depending on the position within the bay.

Objectives:Ginkgo-Chunghyul-dan (GCHD) is newly developed herbal medicine to prevent and treat stroke. In this study, we investigated whether the GCHD had antioxidant activity and anti-platelet aggregation effect in vitro and hypolipidemic activities in vivo. Methods:Anti-oxidant activity of GCHD was measured using the Blois method, anti-platelet effect of GCHD was assessed by the Born method, and hypolipidemic activities of GCHD were evaluated in corn oil- or Triton WR-1339-induced and cholesterol-fed rats. Results:GCHD showed anti-oxidant activity in the study inhibiting the formation of 1-diphenyl-2-picrylhydrazyl radicals and xanthine oxidase activity. GCHD had anti-platelet aggregation activity. GCHD significantly lowered total cholesterol (TC), triglyceride (TG), and low density lipoprotein cholesterol (LDL-C) in high cholesterol diet and Triton WR-1339 induced model TG in corn oil-induced model. GCHD had no acute toxicity at a single dosage. Conclusion:These results suggest that GCHD has the potential to treat hyperlipidemia and stroke.
