  • The effect of capsaicin (0.02%) on the concentrations of liver and serum lipids, GOT and GPT activities, and hepatocyte morphology in male Sprague Dawley rats fed diets with or without erotic acid (1.0%) for 28 days was studied. Liver triglyceride concentration was increased by approximately 4.7-fold after erotic acid-feeding, wherease simultaneous feeding of capsaicin and erotic acid reduced its concentration by 38%. Orotic acidfeeding elevated liver cholesterol concentration, but an addition of capsaicin to the erotic acid diet resulted in the significant decrease in liver cholesterol. Capsaicin alone did not affect the liver triglyceride and cholesterol concentrations. Reduction of the serum concentrations of triglyceride and cholesterol by capsaicin was also observed in rats fed diets with erotic acid. The serum GOT and GPT activities were not significantly different among the experimental groups. Liver tissue morphology showed that the hepatocytes of erotic acid-feeding rats were a typical fatty liver with numerous fat droplets, whereas simultaneous feeding of capsaicin with erotic acid reduced the size and numbers of fat droplets. The present study demonstrated that the diet containing 0.02% capsaicin can prevent the erotic acid-induced fatty liver.

  • 새로운 간장질환 치료제로 개발중인 YH439가 orotic acid, nicotinamide 및 ethionine에 의해 유발되는 지방간에 대한보호 및 치료효과를 관찰하였다. 웅성 SD계 rat에 orotic acid(1%) 또는 nicotinamide(2%)가 첨가된 사료를2주간 섭취시켜 유발된 지방간에 대한 YH439의 보호 및 치료효과와 ethionine(100mg/kg, i.p.)투여로 유도되는 지방간에 대한 YM439의 보호효과를 관찰하기 위하여 간 조직 중 triglyceride, cholesterol 및 phospholipid의 함량을 측정하여 비교하였다. 그 결과, erotic acid 또는 nicotinamide의 섭취로 인해 랫드의 간 조직 중 triglyceride, cholesterol 및 phospholipid의 함량은 1.5-3배정도 증가하였으며, 이 증가된 지질들은 YH439 100, 200mg/kg 투여에 의해 유의성 있게 억제되었다. 또한 ethionine투여에 의해서도 랫드의 간 조직 중 triglyceride, cholesterol 및 phospholipid의 함량은 약 2배정도 증가되었으며, YH439 전저치에 의해 이 현상들이 억제되는 효과를 나타내었다.

  • The antioxidative activities of capsaicin (Cap, 0.02 and 0.04%) on the lipid peroxidation of tissues in male Sprague Dawley rats fed diets with or without orotic acid (1.0%, w/w) were studied in vivo system by measuring thiobarbituric acid reactive substances (TBARS) concentrations. Body weight gain, food intakes, food efficiency ratio and the relative tissues weights of brain, kidney, spleen, heart, and testis were not significantly different among dietary groups. Relative weights of liver were higher in the OA group than that in the other groups. TBARS concentrations in liver were significantly higher in the OA or 0.04% Cap groups than in the normal group, while this raise was not observed 0.02% Cap group. A significant increase in TBARS concentrations was found in the liver of the OA +0.04% Cap group compared with the OA or the 0.04% Cap groups. Nonheme iron concentrations were significantly higher in the liver of the OA, 0.04% Cap, OA+0.02% Cap, OA+0.04% Cap groups than that in the normal group. TBARS concentrations in kidney were lower in the 0.02% or 0.04% Cap groups than that in the normal group, but this concentrations were higher in either the OA, OA+0.02% Cap or OA+0.04% Cap groups than that in the normal group. Meanwhile, TBARS concentrations of brain, spleen, heart and testis were not significantly different among groups. The present study suggested that the lipid peroxidation was increased in the rats liver fed diet with erotic acid, and the simultaneous supplementation of capsaicin further enhanced.

  • Two kinds of simple and interesterfying mixed rapeseed oil were prepared according to add 30%, 50% and 70% of coconut and palm oil, then the physicochemical propecties such as the tedency of oxidation, foaming activity were Investigated. The initial AV and POV of interesterifyung mixed rape-seed oils were higher than those of simple mixed oils, but the tendencies of oxidation were similar. The intial value of IV interesterfied rapeseed oils was added in simple mixed rapeseed oil, Induction period were increased about 2.4~4 times. Induction period of intereterifyng mixed oils added palm ell increased about 2~3.2 times. While the foaming Buantity of interesterifing mixed rapeseed oils with palm oil were lower about 28~40% than those of the simple mixed rapeseed oils.

  • Changes in erotic acid (OA) contents of raw milk and during cultivation and storage at refrigerated temperature were determined. OA contents of raw and 10% reconstituted milk held at $121^{\circ}C$ for up to 15 min decreased by 17.6 and 22.4%, and those fermented at 40 and $37^{\circ}C$ for 72 hr with Lactobacillus helveticus 166 and Lactobacillus casei 955 decreased 37.8-43.2 and 41.8-76%, whereas when fermented at $40^{\circ}C$ for 72 hr with Streptococcus thermophilus ST-37, did not decrease significantly compared with fermentation by other lactobacilli. OA content did not change during storage at refrigeration temperature. OA reduction by Lactobacillus sp. was dramatically increased at the initiation of stationary phase during fermentation. OA reduction varied among different lactobacilli. These results show decrease in cultivation time, rapid cooling of yogurt, and proper selection of Lactobacillus sp. prevent OA content reduction.

  • The purpose of this study is to analyze the present fashion phenomenon by considering the types of street fashion, the center of avant-grade modern fashion, that shows the origination background and special feature concretely. The times was defined through the 1980's from World War II that street style originated, so the range of study was the 1990's when the street style was influenced by that of the past and was revived. The ways of study were to analyze the records of ideology, art and music connected with the street style from World War II to the present when it has risen. The summary of result is as follows. (1) In the 1940's, Zooties was the jet of desire suppressed by African-Americans that couldn't receive favors socially and economically and Hipsters pursued reformative bebop that made up of soft Jazz. In the 1950's, Modernists were running after Cool Jazz to the minimum. In the 1970's, Funk appered in the sexual desire and erotic strength, and was surfaced from Negro Getto. In the 1980's B-boys & Flygirls showed the street style by the scribble art of slum in the New York. As mentioned above, In the 1990's, Acid Jazz influenced by the Jazz of Negro has been the fashion added to the tradition of musical form that come from eclecticism of Jazz tended Neo-Jazz. (2) In the 1940's, Western style dreamed the country life because of rapid urbanization. In the 1950's, Beat obtained the feeling of liberation from the dissolute life and activity. In the 1960's, Psychedelics showed the freedom affected by the Pop-art and Op-art, and Hippies pursued the true individuality as 'love & peace' life style and the return to nature. In the 1990's, Grunge look influenced by the above has been fashion that shows the practical use of second-hand clothing or patchwork contrary to elitism. (3) In the 1940's, Caribbean style appered in the typical textile color with the center of West Indies. In the 1960's, Rude boys showed the magnificence and difficulty of Jamaica, and Rastafarians had a tendency to come back to the ancient civilization of America. In the 1970's, Two-tone was the simple clothing for harmonizing among human races. In the 1990's, Jamaica look influenced by the above has been the Lege fashion introduced to a high fashion, appearing in the special bright color, applique, unique hair style, and so on. (4) In the 1950's, Sufers pursued natural rhythm, getting out of everything. In the 1970' s, Skaters enjoyed the speed on the paved road. In the 1980's, Casuals emphasized the spirit of cooperation of young-things. In the 1990's, Casual look Influenced by the above has been the fashion that forms the activity, function and strong spirit of cooperation by pursuing comfortable life and sports in the tension of life and variety of modern society. (5) It was hard for Bikers to adjust themselves in society after the war. In the 1950's, Coffee bar cowboys were the reckless running boys in the leather jacket. In the 1960's, Rockers created the group originality as disobedient outsiders and Greasers imitated Rolling Stones. In the 1980's, Punks resisted the viewpoint of the old generation in offensive fashion. In the 1990's, Cyberpunk influenced by the above has pursued the classless structure, electronic music and metallic clothing that forebodes gloomily as the computer generation of ultra-modern science times. Accordingly, in understanding a complex modern fashion phenomenon, it was analyzed that the street styles of the past, from World War II to the 1980's, were reflected in that of the 1990's dividing into the five types in a word, namely Acid Jazz, Grunge look, Jamaica look, Casual look and Cyberpunk.
