抗酸化劑 및 有色容器가 해바라기 기름의 抗酸化效果에 미치는 影響
尹衡植 慶北大學校 1977 論文集 Vol.23 No.-
The relative effectiveness of the antioxidant activity resulted from the irradiation of direct sunlight was studied by the changes of free fatty acid value and iodine value in the sunflower oil under three different conditions-colorless, blue and brown colored container during the storage In order to investigate the effect of multiplication of the antioxidants, B.H.A and B.H.T were added respectively to the plots of blue and brown at a level of 0.05%. The obtained results were as follows. The formation of free fatty acid and the reduction of iodine value in the colored contained were more retarded than in the colorless container, and between the plots of blue and brown the latter showed more restraint effect than the former during the storage. With the addition of antioxidants in colored containers, the antioxing effects showed practically similiar to all plots but with the addition of B.H.T in the plot of brown showed multiplication effect. Generally, the multipiccation effect of antioxidients showed in the order of brown blue, in the colored container, and with addition of antioxidants in the colored, it showed brown BHT>brown BHA>blue BHT>blue BHA.

윤형식,박진상,Yoon, Hyung-Sik,Park, Jin-Sang 한국식품과학회 1985 한국식품과학회지 Vol.17 No.4
비이용 자원의 효율적인 이용의 가능성을 검토하기 위하여 앵두씨의 지방질 조성 및 단백질 패턴을 분석한 결과는 다음과 같다. 일반성분 중 조지방질과 조단백질의 함량은 각각 40.38% 및 26.59%였다 앵두씨의 지방질은 중성지방질이 95.4%인 반면에 복합지방질은 4.51%에 불과하였으며, 중성지방질의 성분으로는 트리-글리세리드가 89.86%로서 대부분이었고. 스테롤 4.14%. 모노-글리세리드 2.98%, 스테롤 에스테르 1.77%. 유리지방산 1.07% 및 디 -글리세리드 0.18% 였다. 지방산 조성은 총 지방질, 중성지방절 및 트리 글리세리드에서 올레산(65.06$\sim$66.05%)와 리놀레산(26.56$\sim$28.40%)이 주된 구성 지방산이었고, 당지방질파 인지방질의 경우에는 올FP산(40.55$\sim$51.46%)의 함량이 다른 획분의 함량에 비해 적은 반면, 팔미트산(17.64$\sim$21.43%)과 스테아르산(4.14$\sim$8.07%) 의 함량이 높았으며, 소량의 라오르산도 함유되어 있었다. 염용해성 단백질의 추출율은 약 60%였으며, 분획된 주단백질의 수득율은 약 46.5% 였고 전기영동 결과 7개의 밴드가 확인되었다. Prunus tomentosa Thunberg seed was investigated to evaluate its possibility for use as food resources of fats and proteins. The seed contained 40.38% of crude fat and 26.59% of crude protein. The lipid fractions obtained by silicic acid column chromatography were mainly composed of 95.49% of neutral lipids, whereas compound lipids were only 4.51%. Among the neutral lipid components by thin-layer chromatography, triglycerides were 89.86%, sterols, monoglycerides, sterol esters, free fatty acids and diglycerides were 4.14%, 2.98%, 1.77%, 1.07%, and 0.18%, respectively. Oleic acid (65.06-66.05%) and linoleic acid (26.56-28.40%) were the main fatty acids in the total lipid, neutral lipid and triglyceride fractions. In the glycolipid and phospholipid fractions, predominant fatty acids were oleic acid (40.55-51.46%), linoleic acid (20.26-30.89%) and palmitic acid (17.64-21.43%). The extractability of salt soluble protein of seed was 60%, and recovery rate of main protein fraction separated by Sephadex G-200 was about 46.5%. The electrophoretic analysis showed 7 bands in seed protein.
가자(Terminalia chebula Retz)추출물의 항산화효과
장성준,이기동,김정숙,윤형식 慶北大學校農業科學技術硏究所 1992 慶北大農學誌 Vol.10 No.-
탈지 가자박으로 부터 free, soluble 및 insoluble bound phenolic acids를 추출하여 식용대두유 기질에서 항산화효과를 0.02%(w/w)의 BHA, BHT의 항산화 효과와 비교하고자 각 기질과 대조구를 60±1℃에서 35일간 저장하면서 매 7일 간격으로 과산화물가, TBA가를 측정하였다. BHA, BHT와 free, soluble 및 insoluble bound phenolic acids를 첨가한 시험구와 대조구의 과산화 물가는 21일의 경우 60, 30, 14, 11, 10, 100이었다. 같은 조건하에서 추출물의 TBA가는 0.150, 0.108, 0.073, 0.078, 0.185이었다. 이것으로 보아 phenolic acids는 식용대두유 기질에서 우수한 항산화력을 나타내었다. 분리확인된 phenolic acids는 p-coumaric acid, ferulic acid, phloroglucinol, pyrogallol, vanillic acid, caffeic acid으로 확인되었다. In this study, antioxidtive effectiveness of BHA, BHT at 0.02%(w/w) was compared with those of separated free phenolic acid, ester form and insoluble bound phenolic acid which were extracted from 50g of Terminalia chebula Retz by MeOH/aceton solvents. Antioxidative effectiveness was measured by peroxide values and TBA values for 7days, storaging respective substrates and contrast tube at 45±1℃ for 35days. Laboratory tubes was added by BHA, BHT, separated free, soluble and insoluble phenolic acid extracts and peroxide value of contrast tube after 21 day storage were 60, 30, 14, 11, 100. On the other hand, at the same conditions, TBA values of each antioxidants were 0.150, 0.108, 0.105, 0.073, 0.078, 0.185. This results remarkably appeared antioxidative effectiveness in meal soybean oil substrates. Phenolic acid separated and identificated were p-coumaric acid, Ferulic acid, Phloroglucinol, Pyrogallol, Vanillic acid and Caffeic acid.
유기인계농약 중독환자에서 급성췌장염의 합병증으로 인해 뒤늦게 발생한 급성 폐손상 1례

Organophosphate insecticides are used globally and are household items in rural areas of Korea. Their ingestion for a suicidal purpose is common in Korea. Respiratory failure is the most serious manifestation and the usual cause of death in acute organophosphate poisoning, and is usually common during acute cholinergic crisis. But, respiratory failure may appear suddenly in a patient who is recovering from a cholinergic crisis, even while receiving conventional therapy. Most of these respiratory failures are associated with intermediate syndrome or pneumonia. In several recent studies, acute pancreatitis as a complication of organophosphate poisoning has been shown to be not a rare condition and respiratory failure may also occur in acute pancreatitis. However, acute lung injury developing as a complication of organophosphate intoxication-induced pancreatitis has not been hitherto reported in Korea. We described a case of a 50-year-old woman who had acute organophosphate intoxication-induced acute pancreatitis. The patient developed acute lung injury on the eighth day hospital day, after cholinergic crisis, without intermediate syndrome and pneumonia. Exclusion of other causes indicated that the acute lung injury may have developed due to acute pancreatitis.
動物의 部位에 따르는 水溶性遊離 Amino酸의 分布에 對한 硏究(第三報) : 韓國産 在來種 山羊의 骨에 對하여 on bone of Korean Goats
尹衡植,毛麒喆,朴元吉 慶北大學校 1963 論文集 Vol.7 No.2
The authors carried out the studies on the distribution of water soluble free amino acid in bones and marrow of korean native goat, by using paper chromatography method. The results obtained may be summarized as follows: 1. Amino acid detected in common in both marrow and bones are Arginine and Glutamic acid. 2. Varieties of amino acid are more in the bones than in the marrow. 3. The reis no considerable difference in varieties of amino acid between bone and catrilage, but generally more in bones than in cartilage. 4. In the vertebrae thoracale more varieties and amounts of amino acid are estimated in comparison with other bones. 5. In the medulla osseum less varieties of amino acid is detected compared with bones: Arginine and Glutamic acid are negrigible.
