title: The nutritional effect of a-linolenic acid-rich emulsion with total parenteral nutrition in a rat model with inflammatory bowel disease.
abstract: The purpose of this study was to investigate the nutritional effect of perilla oil emulsion (POE) in a rat model with inflammatory bowel disease (IBD) induced by 2,4,6-trinitrobenzenesulfonic acid. POE and soybean oil emulsion (SOE) were infused at 20% of nonprotein energy during 7 days' total parenteral nutrition (TPN). After infusion of test solutions, body weight gain and cumulative nitrogen balance in the POE group were significantly higher than those in the fat-free TPN (FF) group after infusion of test solutions. Moreover, those in the POE group were higher than those in the SOE group, but no significant difference was observed between the POE and SOE groups. In the POE group, total cholesterol and phospholipid concentration in the plasma was significantly decreased compared with the FF and SOE groups. Triglyceride concentration in the plasma did not significantly differ between the POE, SOE and FF groups. Plasma lipid peroxide concentration in the POE group was significantly lower than that in the SOE group, but it was not different from the FF group. In fatty acid composition in the plasma total lipids, linoleic acid in the POE and SOE groups and alpha-linolenic acid in the POE group were significantly increased compared with those in the FF group. Arachidonic acid (AA) in the POE and FF groups were significantly decreased compared with that in the SOE group. Otherwise, eicosapentaenoic acid (EPA) in the POE group was significantly increased compared with that in the SOE and FF groups. EPA/AA ratio in the POE group was significantly increased compared with the SOE group. The thickness and damage score of the colon were significantly depressed in the POE group compared with the SOE group. These results suggest that POE has a superior nutritional effect and improves inflammation in the IBD.
