  • Hemangioma and vascular malformation are the most common benign tumors that are caused by congenitally or traumatic events. Theses tumors represent approximately 1/3~1/4 of all hemangiomas and vascular malformations in the head and neck. There are many forms of treatment for hemangioma and vascular malformation including closed observation, surgery, radiotherapy, laser therapy, steroid therapy, compression, embolization, and sclerotherapy. Ethanolamine oleate is an unsaturated fatty acid salt that has been used as a sclerosing agent because of its excellent thrombosing properties. This paper presents 1 case of intraoral multiple venous malformations treatment with 1.25% ethanolamine oleate (3.6~9.6 mg dose) intralesionally injected for 6 to 14 weeks over 2 week intervals. After the sclerotherapy, lesions almost completely disappeared without side effects. In conclusion, sclerotherapy using ethanolamine oleate is very effective against venous malformations, and sufficiently provides alternative support for surgical and other methods.

  • The role of each supplement in serum-free medium KM3 for the growth of hybridoma and the production of monoclonal antibody was investigated. Transferrin, ethanolamine and bovine serum albumin were shown to be indispensable for the growth of four kinds of hybridoma tested in this work, especially transferrin for Alps 25-3, and ethanolamine for A4W and KW hybridoma. The addition of $\beta$-mercaptoethanol to the culture medium of HCGK showed a good influence of both the cell growth and the production of monoclonal antibody. Upon the experimental results, we suggested a serum-free medium containing a minimum composition for the culture of hybridoma.

  • The level of long-chain n-3 fatty acids in chicken and pork can be increased by changing the diet of the animals. Increased levels of these essential fatty acids improve cardiovascular health in humans. The purpose of this study was to study the effects of the consumption of pork and chicken enriched in docosahexaenoic acid (DHA) on plasma lipids. The consumption of these products decreased the levels of two cardiovascular risk factors, LDL-cholesterol and triacylglycerols, in the plasma of female college students. The effect on LDL-cholesterol differed from that of fish oil, which does not affect the level of LDL-cholesterol. The proportions of DHA in the triacylglycerols and the glycerophospholipids were increased markedly. The greatest changes in the glycerophospholipids were in the ether types of the ethanolamine glycerophospholipids. Dietary DHA appears to be incorporated preferentially into the plasma ethanolamine plasmalogens, which can act as antioxidants. This agrees with our hypothesis that DHA stimulated the transcription of the genes for peroxisomal enzymes that are required for plasmalogen synthesis.

  • The purpose of this study was to investigate the effect of salt formation on the percutaneous absorption of meloxicam through hairless mouse skin from a pressure sensitive adhesive (PSA) matrix. In addition, the influences of enhancers on the permeation of meloxicam or meloxicam-ethanolamine (MX-EA) salts across the hairless mouse skin were evaluated using a flow-through diffusion cell system. The salt formation of meloxicam resulted in lower permeation rate than the parent drug. $Span^{(R)}$ 80 provided the highest enhancing effect for meloxicam and meloxicam monoethanolamine salt. The maximum amount of the drug that can be loaded without retarding permeation rate was different depending on the compound. No relationship was found between the fluxes of meloxicam or MX-EA salts from saturated solutions and those from PSA matrices containing the same enhancer.

  • The major cause of paper deterioration is the acid-catalyzed hydrolysis of the cellulose in paper fibres. The deacidification of paper reduced the rate of this deterioration, and it has been reported to extend the useful life of acidic paper by three to five times. It has been recognized the need for an effective method of deacidifying large quantities of books and documents. T도 review of the current state of deacidification technology has been published recently. The paper points to the immediate need for a cost-effective and reliable method to save the millions of books that prish every year. It was tried to deacidify by the gaseous ethanolamine for solving with the above the problem. Acidic paper was treated with the monoethanolamine, diethanolamine, triehtanolamine. It result, it was found that the rate of deacidification was in caused very little grightness and fold endurances. For solving this problem, it was carried with deacidify by combination treatment of the various gaseous ehtnaloamines. In result, decreasing of brightness and fold endurance is reduced.

  • 최근 국내 대부분의 원자력 발전소 2차 계통 중 복수 탈염설비의 운전 시 pH를 제어하기 위해 에탄올아민(Ethanolamine, ETA)를 사용하고 있으나 ETA를 적용한 후 발생하는 폐수에 의한 방류수의 화학적 산소요구량(COD) 및 총 질소(TN)의 증가는 심각한 환경적인 문제를 발생 시킨다. ETA가 강이나 하천과 같은 수계로 유입되면 자연적으로 생분해되기 힘들고, 분해부산물이 증가되어 수질을 악화시킬 수도 있다. 이러한 문제점을 해결하기 위해 본 연구에서는 폐경석, 제강슬래그, 저회를 혼합하여 제올라이트화(zeolitization)과정을 통해 새로운 형태의 저비용, 고효율의 ETA 처리용 복합흡착제를 제조하였다. 최적의 흡착 및 이온교환능력을 갖는 복합흡착제는 폐경석, 제강슬래그 및 저회의 혼합조성비를 Mixture Analysis 통계법을 통해 도출하였다.

  • This study was conducted to examine whether a specific synthetic metalworking fluid (MWF), "A", in use for 10 months without replacement, displayed microbial resistance and to identify the additives associated with the control of microbial growth. Three synthetic MWF products ("A", "B", and "C") were studied every week for two months. Microbial deterioration of the fluids was assessed through evaluation by endotoxin, bacteria and fungi levels in the MWFs. In addition, formaldehyde, boron, ethanolamine, and copper levels were also studied to determine whether they influence microbial growth in water-based MWFs. Throughout the entire study in the sump where MWF "A" was used, bacteria counts were lower than 103 CFU/mL, and endotoxins never exceeded 103 EU/mL. These levels were significantly lower than levels observed in sumps badly deteriorated with microbes. Boron levels in MWF "A" ranged from 91.7 to 129.6 ppm, which was significantly higher than boron levels found in other MWF products. The total level of ethanolamine (EA) in MWF "A" ranged from 35,595 to 57,857 ppm (average 40,903 ppm), which was over ten times higher than that found in other MWFs. Monoethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA) concentrations in MWF "A" were also significantly higher than seen in other MWFs. However, although EA and boron might improve anti-microbial performance, their abuse can pose a serious risk to workers who handle MWFs. From an industrial hygiene perspective, our study results stress that the positive synergistic effect of boron and EA in reducing microbial activity in MWF must be balanced with the potentially negative health effects of such additives. Our study also addresses the disadvantage of failing to comprehensively report MWF additives on Material Safety Data Sheets (MSDS). Future research in MWF formulation is needed to find the best level of EA and boron for achieving optimal synergistic anti-microbial effects while minimizing employee health hazards.

  • A synergistic effect was observed in the combination of nitrite and ethanolamines. Ethanolamine is one of the representative organic corrosion inhibitors and can be categorized as adsorption type. However, nitrosamines can form when amines mix with sodium nitrite. Since nitrosamine is a carcinogen, the co-addition of nitrite and ethanolamine will be not practical, and thus, a non-toxic combination of inhibitors shall be needed. In order to maximize the effect of monoethanolamine, we focused on the addition of molybdate. Molybdate has been used to alternate the addition of chromate, but it showed insufficient oxidizing power relative to corrosion inhibitors. This work evaluated the synergistic effect of the co-addition of molybdate and monoethanolamine, and its corrosion mechanism was elucidated. A high concentration of molybdate or monoethanolamine was needed to inhibit the corrosion of ductile cast iron in tap water, but in the case of the co-addition of molybdate and monoethanolamine, a synergistic effect was observed. This synergistic effect could be attributed to the molybdate that partly oxidizes the metallic surface and the monoethanolamine that is simultaneously adsorbed on the graphite surface. This adsorbed layer then acts as the barrier layer that mitigates galvanic corrosion between the graphite and the matrix.

  • The present investigation was performed to find the lipid composition of the total lipids, the fatty acid components of the neutral lipids and the phospholipids, and the composition of sterols, from Spisula sachalinensis. The results obtained are as follows ; 1) The main components of the total lipids are phospholipids$(43.1\%)$, triglyceride$(36.2\%) $, and sterol $(10.3\%)$. 2) The phospholipids are mainly composed of phosphatidyl choline, phosphatidyl ethanols, mine, phosphatidal ethanolamine and phosphatidyl serine. 3) The main fatty acids of the neutral lipids, the ethanolamine phospholipids and choline phospholpids, are C20:5, C16:1, C16:0, C20:5, C18:0, C22:6 and C16:0, C20:5, C22:6, respectively. Oleic acid content of all fractions is very small compared with one of gastropoda lipids and fish oil. 4) Most of plasmalogen are present in the ethanolamine phospholipids and only trace of plasmalogen in the choline phospholipids. 5) Sterols to be found are 22-trans-norcholesta-5, 22-diene-$3\beta$-ol, 22-dehydrocholesterol, cholesterol, brassicasterol, 24-methylenecho-lesterol and $\beta-sitosterol$.
