In a prospective, randomized and controlled trial, 60 patients with SAP were randomized either to treat with conventional therapy （Con group, n=30） or conventional therapy plus intravenous supplementation with ω-3 fish oil emulsion 0.2 g/kg every day （FO group, n=30）. The effects were analyzed by the SIRS-related indexes. The results showed that APACHE-Ⅱ scores in FO group were significantly lower, and the gap increased much farther after the 4th day than those in Con group （P〈0.05）. Fluid equilibrium time became shorter markedly in FO group than in Con group （5.1±2.2 days vs 8.4±2.3 days）. In FO group, SIRS scores were markedly decreased and the SIRS state vanished after the 4th day; Plasma level of TNF-α was significantly reduced, while IL-10 decreased markedly, most prominently between the 4th and 7th day, and the ratio of IL-10/TNF-α raised as compared with Con group （P〈0.05）. During the initial stage of SAP, parenteral supplementation with ω-3 fish oil emulsion could efficiently lower the magnitude and persistence time of the SIRS, markedly retrieve the unbalance of the pro-/anti-inflammatory cytokines, improve severe condition of illness and may provide a new way to regulate the SIRS.展开更多

In this review, the recent developments by 2019 in the field of enzymatic modification of oils rich in omega 3 PUFAs have summarized. Several different products, such as structured lipids with a variety of FA compositions, nutritional aspects, omega 3 PUFA concentrates and phospholipids,have discussed from the point of process technology as well as possible applications. Enhancing omega 3 PUFA content in diet involves a number of strategies aiming to modify the content of such FAs in fats and oils. Due to the mild reaction conditions used, especially the lipase specificity, the position as well as content of omega 3 PUFAs in lipid molecules being of importance from the point of bioavailability, enzymatic processing of omega 3 PUFA oil is safe, efficient and preferred over chemical treatments.展开更多

Fifty six male albi-no rats were divided into 7 group: first group was fed on normal basal diet (maintained at negative control group), group 2 diabetic group fed on 60% fructose, group 3 fed on 60% fructose + 8% fish oil, group 4 fed on 60% fructose + 8% flaxseed oil, group 5 fed on 60% fructose + 4% corn oil + 4% fish oil, group 6 fed on 60% fructose + 4% corn oil + 4% flaxseed oil and group 7 fed on 60% fructose + 4% fish oil + 4% flaxseed oil. Fatty acid composition of investigated oils show that the corn oil contained high levels of omega-6 fatty acid (LA: 56.95%), flaxseed oil contained high level of short chain omega-3 fatty acid (ALA: 56.31%), meanwhile fish oil only has high concentration of long chain omega-3 fatty acid 39.20% (23.98% of EPA and 15.22% of DHA). After 8 week feeding of fish oil, flaxseed oil, corn oil + fish oil, corn oil + flaxseed oil and fish oil + flaxseed oil show reduces levels of glucose by 49.09%, 44.0%, 43.4%. 43.6% and 44.9% respectively. Data revealed significant decrease (P < 0.05%) was observed of TC, TG, LDL and VLDL of all treatment. Urea and creatinine in diabetic rats was increase, in contrast the glutathione reduced was decrease compared to the control group. Fish oil show the highest decrease in urea and creatinene and the highest increase in glutathione levels and insulin compared to other sources of omega-3. Omega-3 fatty acids have potential effect to protect pancreas from up normality changes which induced in diabetic disease. The data suggest that omega-3 fatty acid and fish oil especially may be effective in the prevention of diabetic disease.展开更多

The trial lasted for 10 weeks and the fatty acid （FA） profile of both feed and fish muscle tissue were examined. There was no difference in growth, feed conversion rate （FCR） and mortality. The fish grew from 10 g to 110 g with a FCR of 1.25 and 0 mortality. The FA profile of the fish muscle tissue reflected the FA profile of the feed. The flesh of the fish that were fed the linseed oil diet, were extremely high in omega-3 （n-3） polyunsaturated FA （n-3 PUFA） with 3.75% of wet weight. This is one of the highest concentrations of n-3 PUFA ever recorded in fish flesh. In a finishing feeding test, the remaining vegetable oil fed fish were fed the fish oil diet for another two weeks immediately after the 10 weeks trial, to check for a possible recovery of n-3 highly unsaturated fatty acids （HUFA）. The wash out rate of FA towards n-3 HUFA in the muscle tissue was about 25% over this two weeks period.展开更多
