Short-term duodenal seal oil administration normalised n-6 to n-3 fatty acid ratio in rectal mucosa and ameliorated bodily pain in patients with inflammatory bowel disease
Bjørkkjær, Tormod; Brun, Johan Gorgas; Valen, Merete; Arslan, Gülen; Lind, Ragna Anne; Brunborg, Linn Anne; Berstad, Arnold; Frøyland, Livar (Peer reviewed; Journal article, 2006-03-20)Background: A high dietary intake of n-6 compared to n-3 fatty acids (FAs) may promote the production of pro-inflammatory eicosanoids and cytokines. In two recent studies, short-term (10- day) duodenal administration of ...
