Feeding-induced OEA mobilization is restricted to the lumen of the rat proximal small intestine. A, Hematoxylin staining of a section of rat duodenum before (left) or after (right) removal of the lumen by scraping with a blunt spatula. Scale bar, 100 μm. Effects of free-feeding (FF), 24-h food deprivation (FD) and refeeding (10, 30 and 60 min) on OEA contents in luminal (B, D) and serosal fraction (C, E) of duodenum (B–C) and jejunum (D–E). *p < 0.05, **p < 0.01, ***p < 0.001 vs FD, n = 10–12.
