The present study was conducted to understand the effect of garlic on hypoglycemia, hypocholesterolemia and anticoagulation in cholesterol-fed male rats(Sprague-Dawley) weighing 100g ±2g and 200g ±2g. They were divided into 12 groups with 6 in each group and were given stock diet (Jaeil rat food) to adjust themselves during 7 days. The groups of 100g rats fed with only stock diet for group A, a mixture of stock diet and 2% cholesterol for group B. and 2%, 3% fresh garlic powder for group CD and 2%, 3% boiled garlic powder for group EF in addition to group B diet respectively. The groups of 200g rats fed with only stock diet for group A, a mixture of stock diet and 2% cholesterol and 0.25% bile salt for group B, and 2%, 4% fresh garlic powder for group CD and 2%, 4% boiled garlic powder for group EF in addition to group B diet respectively. All groups were fed with these experimental diets for 3 weeks were fasted for 15 hours at the end of experiment and decapitated to take serum and anesthetized weakly with ethyl ether to obtain plasma. The serum was used to measure the level of glucose, total cholesterol, triglyceride, HDL-cholesterol and lipoprotein composition. The plasma obtained by cardiac puncture into syringe was used to determinate whole blood coagulation time, prothrombin time, fibrinolytic activity and fibrinogen level. The results are summarized as follows; 1. Garlic diets have no influence on body weight and food intake in cholesterol-fed male rats. 2. Garlic supplemented at 2% and 3% of the diet decreased serum glucose, total cholesterol and triglyceride, but increased HDL-cholesterol as compared to control 3. The / ratio which was 0.51 at the group A rose to 0.99 at the group B. However, this ratio is decreased to 0.41∼0.57 in garlic-fed group C.D.E.F. 4. Fresh garlic supplementation decreased A/G ratio from 2.03 to 1.50-1.70, but boiled garlic has no decreasing effect. 5. Garlic diets increased whole blood coagulaton tome, prothrombin time and fibrinolytic activity, but decreased fibrinogen level in plasma of cholesterol-fed male rats.

界面活性劑의 새로운 誘導體에 關한 硏究[Ⅰ] : 페로센系 界面化合物의 合成 Synthesis of the surface active compounds with Ferocene containing Hydrophobe

李容億,盧長淑 명지대학교 1979 明大論文集 Vol.12 No.-

Ferrocene, bis-(pentaheptocyclopentadienyl)-iron is the most common metallocene. Surface active agents, having non-hydrophobe hydrophobe have been synthesized and used. Whereas ones with perfluoroalkyls and silicone containing organic groups are often utilized, π-metalloarenes and π-metallopseudoarenes have scarecely been used. We synthesized some ferrocenyl carboxylic acid via Friedel-Craft acylation of ferrocene with cyclic anhydride of aliphatic dibasic acids. These ketoacids were, then, reduced to the corresponding ferrocenyl carboxylic acids and their salts.

一部食用油脂의 含有特殊物質에 對한 營養學的 考察

李容億,姜仁姬 명지대학교 1982 明大論文集 Vol.13 No.-

In addition to acting for an element of capacity supplying calorie, edible oil and fat holds a key post as a supply source of oil soluble vitamins and essential fatty acid which can not be synthesized in vivo. Such edible oil and fat passes through various treatments such as treatment of acid and alkali, deordorization, and high temperatured structure by heating in manufacturing and refined processing. By such treatments, glycerine comes to be polimerized and has possibility of forming the chemical compound of high molecule. Particularly, glycerine esterification rice bran oil gives rise to a quetion which is manufactured by heating reaction after the rice bran oil and glycerine heated at a high temprature (160℃-180℃). As it is going through the reaction of oxidation by heating polymer of heat oxidation can be easily organized. It can be said that most of the rice bran oil, selling on the market at present is a rice bran oil contained senescent phenomenon by heating. According, senescent rice bran oil by heating seems to give rise to induce a drop of digestion-rate, quality, etc. with formation of polymer which can hardly absorb and digest, and a drop of nutritive value such as loss of oil soluble vitamins and distruction of essential fatty acid in dietetics. And I began to study with the object of examining the conformation of noxirous ingredients of the rice bran oil, examination of nutritive value, and effect of on human body. For the first step, quality of the rice bran oil which is selling in our domestic market was examined and analysis of fatty acid by gas-liquid chromatography and polymer were examined. And the results are as follows. 1) Collected the rice bran oil at the section of localiy and analyzed chemical nature. 2) The results of the analysis by G.L.C. in order to know the polymer can be formed or not. 3) The rate of acid value, peroxide value, and unsaponifiable matter shows much differences when it is compared with Korean Industrial Standard of edible rice bran oil standard. 4) Iodine value of the local rice bran oil at present ranges from 84 to 108 and saponification value ranges from 142 to 183. 5) Analyzed fatty acids chiefly contained much oleicacid and linoleic acid, and contained 30 to 38.5% of essential fatty acid. 6) 3 of 5 samples of refined oil formed the polymer (G-2,234% J-3,596% K-1,064%) 7) As polymers were not discovered from crude oil and refined rice bran oil in laboratory (alkali refinement), the rice bran oil refiened by a method of alkali will prove desirable.

This experiment was caried out investigating to decrease of egg quality according to various storage temperatures and holding periods. The results of this study which was obtained from 8 storage temperatures during 15 days were as follows. These data were identified that storaged eggs under 20 ℃ below could sustain nearly fresh eggs in egg weight during 15days.In albumin height there were decre asing aspects which showed inverse proportion in increasing temperatures and prol-ongation of holding times. and Haugh Unit which corelated closely with albumin height was calculated similar tendency to that of albumin height. When this unit was transformed from USCA degree, storaged eggs during 15 days at 5℃ were appeared AAdegree, at 10℃ and 15℃ A degree and at 30℃ above during 9 days B degree. Also this research was abserved that holding period influenced strongly to yolk index but storage temperature seemed not to correlated orderly with it.pH of albumin in holding time at high storage temperatures which caused to decay frach egg and increase carbon dioxide density seemed to bo decreased. In linear eqation of egg weight, albumin height and yolk index with holding times. Egg weight and albumin height were showed considerablly higher negative(-) regression coefficient according to prolongation of holding time under 25℃ above compared with that of 20℃ below.
