Impact of marine oils in inflammatory bowel disease and psoriatic arthritis. With focus on effects of seal oil and whale oil on joint pain
Bjørkkjær, Tormod (Doctoral thesis, 2009-09-25)The Western diet has changed significantly over the last century, e.g. by an increased ratio of omega-6 (n-6) to n-3 polyunsaturated fatty acids (PUFA), particularly due to an increase in the use of vegetable oils like soy ... -
Improved Quantification of Prostaglandins in Biological Samples by Optimizing Simultaneously the Relationship Eicosanoid/Internal-Standard and Using Liquid Chromatography Tandem Mass Spectrometry
Araujo, Pedro; Bjørkkjær, Tormod; Berstad, Arnold; Frøyland, Livar (Peer reviewed; Journal article, 2007-07)Although a wide variety of articles on quantification of eicosanoids by using internal standards are published every year, little has been done on how much internal standard should be added. This article demonstrates that ... -

However, about 30% of the patients do not ... -
A randomized double blind comparison of short-term duodenally administrated whale and seal blubber oils in patients with inflammatory bowel disease and joint pain
Bjørkkjær, Tormod; Araujo, Pedro; Madland, Tor Magne; Berstad, Arnold; Frøyland, Livar (Peer reviewed; Journal article, 2009)Compared with soy oil, 10 days treatment with seal oil (SO), 10 mL×3 daily, self-administrated through a nasoduodenal feeding tube, relieves joint pain in patients with inflammatory bowel disease (IBD).
