Three experiment were designed to determine the effects of dietary(n-3) fatty acids on the growth-suppressive effects of the inflammatory response and anti-oxidant enzyme activity and balances of nitrogen and energy. Day-old chicks were fed diets containing 1.0 ％ soybean oil in experiment 1, or diets containing 1.0 ％ of fish oil in experiment 2, and then on 7-d of age chicks were fed diets containing 1.0 ％ of either soybean oil or fish oil. In experiment 3, day-old chicks were fed on diets containing 1.0 ％ of either soybean oil or fish oil. In chicks of half pens within each dietary treatments of each experiments, the acute phase response were induced by injecting with Salmonella typhymurium lipopolysaccaride(LPS) i.p. 3 times at 8, 10 and 12-d of age. During acute phase response, chicks fed dietary fish oil from 1-d of age enhanced energy balances and did not give negative effect on nitrogen balance and uric acid excretion, but elevated MnSOD and Cu/ZnSOD activity In liver and erythrocyte cytosols compared with those fed dietary soybean oil. The results indicated that enhanced daily gain and metabolizable energy value of diet in birds fed fish oil from one-d of age seems due to change on the antioxidants systems during acute phase response.

This study was designed to observe the effects of the fish oil and some seed oils on the improvement of the fatty acid compositions of liver and brain tissue in rats. In order to induce the hypertriglyceridemia in the rats of the Sprague-Dawley, 12% coconut oil and 3% each of olive oil, lard, fish oil, perilla oil, corn oil, red pepper seed oil and evening primrose oil were administered to the rats for 4 weeks. In the fatty acid composition of liver lipid, n-3 PUFA contents were most in the fish oil and perilla oil groups of phospholipid fraction, and n-6 PUFA contents were most in the corn oil, red pepper seed oil and evening primrose oil groups of triglyceride fractions. Fatty acid composition of liver lipid fractions were influenced from the fatty acid composition of the test lipids. In the fatty acid composition of brain phospholipid, n-3 PUFA contents (8.8~17.2%) were most in the fish oil group, and n-6 PUFA (34.6~38.2%), though it contains high percentage, showed little difference between groups.

The influence of selenuium deficiency and fish oil on lipid peoxidation status and fatty acid composition of tissues(plasma aorta and liver) was studied. Male Sprague Dawley rats were fed for eight weeks semipurified diets containing 7% corn oil(by weight) or 5, 5% fish oil(MaxEPA) plus 1.5% corn oil with oil with or without selenium status (glutathione peroxidase activity and selenium levels) were significantly lower in the rats given inadequate selenium in plasma aorta (p<0.02 and p<0.001 respectively) gut not that in plasma Selenium supplementation decreased hepatic MDA levels(p<0.02) Increases in the levels of 20:5(n-3) 22:5(n-3), 22:6(n-3) 20:3(n-6) and a decrease in the level of 20:4(n-6) were observed in plasma total lipids and aortic and hepatic phospholipids when fish oil was fed. Though selenium supplementation increased the level of n-3 fatty acids(such as 22:6(n-3)) in plsama and the aorta is overall effect was smaller than the effect of fish oil feeding. These data suggest that selenium may play a significant but minor role in protecting against lipid peroxide-tion even when vitamin E intakes are in excess of current recommendations in both corn oil and fish oil diets.

This study was designed to investigate the effect of supplementation of fish oil on serum lipid in young healthy females. Eighteen female college students were divided into 3 groups. Each group fed a typical Korean diet supplemented with 15g, 12g and 9g of fish oil respectively for 1 week. Blood samples were obtained 4 times before supplementation, immediatly after supplementation, 1 week after stopping supplementation and 3 week after stopping supplementation. After 6 week break, the doses of fish oil were interchanged among 3 groups and the experiment was repeated to reduce interindivisual variation. The level of total cholesterol(TC), triglyceride(TG), lipoprotein, high density lipoprotein(HDL)-cholesterol, low density lipoprotein(LDL)-cholesterol in the serum samples were determined immediately after stopping supplementation and then the value compared with those of the before supplementation period. The results obtained are summarised as follows; The serum TC levels decreased significatly(p<0.01) immediately after supplementation of fish oil and 1 week after stopping supplementation. The serum TG levels also decreased significantly(p<0.05) immediately after supplementation of fish oil. The HDL-cholesterol levels increased significantly(p<0.05) at 2 week and 3 weeks after stopping supplementation of fish oil in the 12g and the 15g supplementation groups. The LDL-cholesterol levels decreased significantly(p<0.05) immediately after and 1 week after stopping supplementation of fish oil. The ratio of HDL-C to TC increased significantly(p<0.01) and the ratio of LDL-C to HDL-C, and index of artherogenesity, decreased significantly(p<0.05).

Using agar and waxy com starch as the wall material, we could encapsulate the purified fish oil. Firstly, we have developed a simple and sensitive method for the quantitative analysis of the microencapsulation yield using 5% cupric acetate pyridine solution. Then, the optimum conditions such as the ratio of [core material] to [wall material]$(X_1)$, the temperature of dispersion fluid$(X_2)$, and the emulsifier concentration$(X_3)$ for the microencapsulation process were determined by using response surface methodology(RSM). The regression model equation for the yield of microencapsulation(Y, %) of purified fish oil upon three kinds of independent variables could be predicted as follows; Y = 100.138621-0.735000$(X_1)$+0.840000$(X_1)(X_2)$+0.817500$(X_1)(X_3)$-0.852500$(X_2)(X_3)$. And the optimum conditions for the microencapsulation of the purified fish oil were the ratio of [core material] to [wall material] of 4.9 : 5.1(w/w), the emulsifier concentration of 0.48%, and dispersion fluid temperature of $19.4^{\circ}C$. The microcapsules containing the purified fish oil showed the highest storage stability at pH 7.0 and $20{\sim}25^{\circ}C$.

Structured lipids(SLs) were synthesized by enzymatic interesterification with DHA-enriched fish oil(containing 27% docosahexaenoic acid) and soybean oil in the hatch-type reactor. The interesterification was performed for 24 hr at $55^{\circ}C$ and TLIM(immobilized lipase from Thermonyces lanuginosa, 10% by weight of total substrates) was mixed with 180 rpm of shaking. The fish oil and soybean oil were interesterifed with several weight ratio(fish oil : soybean oil, 2:8, 3:7, 4:6, 5:5, w:w), Reverse-phase high performance liquid chromatography with an evaporative light-scattering detector separated the triglyceride species of SLs. The products contained the newly synthesized peaks. Especially, one of peaks was distinctively increased with the increasing weight ratio from 2:8 to 5:5 while the peak of trilinolein (LLL) decreased vice versa. The effect of antioxidants such as catechin, BHT(Butylated hydroxytoluene), and their combinations on the oxidative stability in SL were investigated. Oxidative stability was carried out under oven test at $60^{\circ}C$ over 72 hr thereafter SLs were analyzed for total fatty acid content, rancimat, peroxide value, electronic nose and TBARS value. Among all combinations of antioxidant, the highest stability was obtained from 200 ppm of catechin. Besides, total tocopherol ($\alpha$, $\gamma$, and $\delta$-tocopherol), iodine and saponification value were analyzed in which iodine and saponification value of SLs were 151.19 and 182.35.

해양자원으로부터 상업적인 가치를 지니는 천연물질들을 획득하는 것은 일본의 수산업에 있어서 매우 중요하다. 일본에서는 해양자원의 부산물을 이용하여 다양하고 많은 상업적인 제품들을 성공적으로 개발하고 있다. 키틴, 키토산, 어유, 액정(liquid crystal), 프로타민(protamine, 식품에 향균제로 사용되며 물고기의 고환으로부터 얻음), 어류양식장에서 사용하는 성장호르몬, 해양생물로부터 추출하는 몇가지 의약품 등이 대표적인 예이다.
