Does krill oil improve Crohn's symptoms?

Krill oil from Wikipedia

"Dietary supplementation of krill oil attenuates inflammation and oxidative stress in experimental ulcerative colitis in rats" in Scandinavian Journal of Gastroenterology (2012)
"KO showed protective potential against DSS colitis based on the preservation of colon length, reduction of oxidative markers and the consistent beneficial changes of HCS, cytokine, and (PG)E3 levels, as well as PPAR-γ and Pparg1α expression compared with DSS alone. These findings indicate an anti-inflammatory and a protein antioxidant effect of KO."
