崔炳甲,李始炯 대한동의병리학회 1998 동의생리병리학회지 Vol.12 No.2

애역(딸꾹질)에 대한 韓方的 文獻考察을 통하여 原因, 機轉, 症狀, 治法, 治方을 考察한 후 西洋醫學的 觀點을 비교·검토하여 韓洋方에 대한 애역의 관점차이와 서로 유사한 점을 비교하여 보았다. 딸꾹질은 일생동안 누구나 경험하는 疾患이며 대개 일시적인 症狀으로 곧 소실되지만 난치성 딸꾹질은 기질적인 원인질환이 있는 경우가 많으며, 韓方에서는 애역의 原因을 대체로 胃氣의 降濁失調로 因한 胃氣上逆으로 보았다. 韓方的인 觀點이 주로 辨證論治를 爲主로 하여 發展한데 반하여 洋方的인 觀點은 主로 原因疾患이 先行된 경우는 선행되어진 原因疾患을 위주로 한 치료와 대증적 약물요법, 수술요법 등의 治療方法으로 귀납되었다. 향후 韓方的 觀點과 洋方的 觀點의 상호이해를 통한 지속적인 硏究가 필요하다고 사료된다. Through the bibliographic study between oriental and western medicine about hiccup, I studied difference and similarity between oriental and western view point of hiccup. We have experienced at least one more hiccup for whole life. General hiccup disappears soon, but incurable one mostly happens under the organic disease. On the point of view of oriental medicine, We have regarded cause of hiccup as adverse rising of the stomach-qi(胃氣上逆). In orient the treatment of hiccup has been mostly progressed through diagnosis and treatment based on overall analysis of symptoms and signs(辨證論治), but in western that has been mostly done through treatment of disease(pharmacotherapy, operative therapy) which causes hiccup. It is thought that the persistant study about hiccup should be continued under the reciprocal correspondence between orient and west. 1. Adverse rising of the stomach-qi(胃氣上逆), the most general cause of hiccup is caused by failure of descending of the stomach-qi(胃氣降濁失調). And hiccup can be caused by cold and deficiency syndrome of the stomach(胃中虛寒), deficiency syndrome of the stomach and the spleen(脾胃虛), adverse rising of stomach fire(胃火上衝), phlegm retention(痰飮), exopathic disease(外感傷寒), elongated disease(久病), indigestion(食滯), emotional stress(情志不舒) and deficiency syndrome of liver and kidney-Yin(肝腎陰虛). Adverse rising of the stomach-qi(胃氣上逆), cold and deficiency syndrome of the stomach(胃中虛寒), deficiency syndrome of the stomach and the spleen(脾胃虛), adverse rising of the stomach fire(胃火上衝) and indigestion(食滯) which cause hiccup are similar to the stimulus or distension of the G-I tract, peritonium and diaphragm on western medicine. Exopathic disease(外感傷寒) is similar to any kinds of infectious disease. Elongated disease(久病) is similar to uremia, diabetes and electrolytic unbalance. Emotional stress(情志不舒) is associated with psychogenesis. 2. There are several treatment methods of hiccup, such as warming the middle jiao(溫中祛寒), regulating the stomach and preventing hiccup(화위지애), regulating the flow of qi to resolve the phlegm(理氣化痰), promoting the production of the body fluid and nourishing the stomach(生津養胃) and clearing away heat(淸降泄熱), which are adapted to each cause of hiccup. These are similar to western pharmacotherapy of the sedative and anticonvulsant for decreasing stimulation of the stomach, diaphragm and peritonium. 3. Sternutatory(취체법) and the insufflations(후법) such as sulphur insuflation(유황후법) and arsenic trioxide insufflation(웅황후법) are similiar to several methods, such as sternutatory, pharynx stimulation and gas insufflation method, for inhibiting the afferent fiber of vagus nerve on non-medication therapy.

편도중심핵에 대한 Dopamine성 물질의 투여가 스트레스성 위궤양에 미치는 영향

장현갑,윤병수 한국심리학회 1993 한국심리학회지 생물 및 생리 Vol.3 No.1

본 연구는 편도중심핵의 dopamine(DA)이 스트레스성 위궤양에 미치는 영향을 알아보기 위한 것이다. 편도중심핵에 양측으로 DA(10㎍)과 DA길항물질인 haloperidol(10㎍), 그리고 식염수를 투여하였다. 약물처치후 3시간동안 저온-구금시킨후 뇌와 위를 적출하여 뇌의 손상 부위를 검색하고 위궤양 발생정도를 평정하였다. 그 결과는 다음과 같다. DA처치 집단은 식염수 집단보다 위궤양 발생정도가 유의미하게 낮았으며, haloperidol처치집단은 DA처치집단과 식염수집단보다 유의미하게 높았다. 이러한 결과는 편도중심핵이 DA의 위궤양 억제효과를 중재하는 중요한 구조임을 시사한다. The present study was undertaken to investigate the effects of dopamine(10㎍), haloperidol(10㎍) and saline injected bilaterally into the central amygdala. After drug treatment the rats were immobilized individually in supine-restraint devicers at 4℃ for 3hr. The results were as follows: DA had an attenuating effect on gastric ulcers, but haloperidol had and aggravating effect. These results indicate the central amygdala is important in the mediation of the ulcer attenuating effect of dopamine.

벨로우즈 해석을 위한 유한요소의 개발에 관한 연구

고병갑,박경진,이완익 한양대학교 공학기술연구소 1995 공학기술논문집 Vol.4 No.1

Bellows is a familiar component in piping systems as it provides a relatively simple means of absorbing thermal expansion and providing system flexibility. In routine piping flexibility analysis by finite element methods, bellows is usually considered to be straight pipe runs modified by an appropriate flexibility factor; maximum stresses are evaluated using a corresponding stress concentration factor. The aim of this study is to develop a bellows finite element, which similarly includes more complex shell type deformation patterns. This element also does not require flexibility or stress factors, but evaluates more detailed deformation and stress patterns. The proposed bellows element is a 3-D, 2-noded line element, with three degrees of freedom per node and no bending. It is formulated by including additional 'internal' degrees of freedom to account for the deformation of the bellows corrugation; specifically a quarter toroidal section of the bellows, loaded by axial force, is considered and the shell type deformation of this is include by way of an approximating trigometric series. The stiffness of each half bellows section may be found by minimising the potential energy of the section for a chosen deformation shape function. An experiment on the flexibility is performed to verify the reliability for bellows finite element.

편도중심핵의 dopamine성 체계가 스트레스성 위궤양에 미치는 영향

장현갑,윤병수,박순권 한국심리학회 한국심리학회지 생물 및 생리 Vol.4 No.1

본 연구는 스트레스성 위궤양발생과 편도중심핵의 dopamine(DA)와의 관계를 알아보기 위해 두가지 실험을 실시했다. 실험1에서는 DA성 신경원을 손상시키는 6-OHDA를 편도중심핵에 주입하여 DA성 신경원을 손상시킨후 저온-구금스트레스에 의한 스트레스성 위궤양발생정도를 비교하였고, 실험2에서는 DA효능물질인 apomorphine과 DA길항물질인 haloperidol을 편도중심핵에 주입한 후 저온-구금스트레스에 의한 위궤양발생정도를 비교하였다. 실험1의 결과에서는 6-OHDA처치에 의한 편도체 중심핵 손상집단이 saline통제집단 보다 유의미하게 높은 위궤양발생을 보여주었고, 실험2에서는 DA효능물질인 apomorphine처치집단이 saline통제집단보다 유의미하게 낮은 수준의 위궤양발생을 보여주었지만, DA수용기 차단물질인 haloperidol처치집단은 saline통제집단과 apomorphine처치집단에 비해 유의미하게 높은 위궤양발생을 보여주었다. 위의 두실험의 결과로 미루어 볼때 편도중심핵의 DA성 신경원과 여기에서 분비하는 DA가 스트레스성 위궤양발생에 중요한 역할을 하는 것으로 추측할 수 있다. To investigate the effects of central amygdala dopamine on immobilization stress-induced gastric ulcer in rats, two experiments were conducted. In experiment 1, 6-OHDA(10㎍) was injected bilaterally into central amygdala to destroy dopaminergic neurons. On 7 days after drug treatment the rats were immobilized individually in supine-restraint devicers at 4℃ for 3hrs. The results of experiment 1 were as follows: lesion of dopaminergic neurons in central amygdala aggravated the gastric ulcer induced by stress. In experimemt 2, apomorphine(10㎍), haloperidol(10㎍) and saline were injected bilaterally into central amygdala. At 30min after drug treatment the rats were restrainted at 4℃ for 3hr. The results were as follows: apormophin had an attenuating effect on the gastric ulcers, but haloperidol had an aggravating effect. These results indicate that dopaminergic neurons and dopamine of central amygdala does play an important role in the stress-induced gastric ulcer.

서현호,정병운,전기일,김형갑 진주산업대학교 환경문제연구소 1998 環境硏究論文集 Vol.2 No.-

Flavobacterium sp. BEN2 was selected and identified out of 64 benzene-degrading bacteria isolated from soils and waste waters by the enrichment culture technique. The optimal temperature, pH, and benzene concentration for the growth of Flavobacterium sp. BEN2 appeared to be 30℃, 7.0 and 2000 ppm, respectively. Cell growth almost revealed a stationary phase at 24 hours after cultivation and benzen was completely degraded during as benzen, benzoic acid, phenol, p-cresol, salicylic acid, catechol, gentistic acid and toluene, but did not grow ob o-cresol, m-cresol, p-xylene and p-toluic acid. With this strain, catechol was degraded through both meta- and ortho- cleavage pathway. Therefore, it is suggested that Flavobacterium sp. BEN2 could be effectively used for the biological treatment of wastewater containing benzene in the presence of some aromatic compounds and organic solvents.
