Acer palmatum thumb. Ethanol Extract Alleviates Interleukin-6-Induced Barrier Dysfunction and Dextran Sodium Sulfate-Induced Colitis by Improving Intestinal Barrier Function and Reducing Inflammation

The protective effect of KIOM-2015E in the dextran sodium sulfate- (DSS-) induced colitis model. (a) Endoscopy image. (b) Hematoxylin and eosin staining (H&E) staining. (c) Alcian blue staining. (d) PAS staining. On the 8th day of experiments, we confirmed the DSS-induced mucosal damage using a mini-endoscope. After the endoscopy procedure, collected intestinal tissues were fixed with 4% paraformaldehyde solution, embedded in paraffin block, and sectioned using a microtome. Histological sections were stained with hematoxylin and eosin (H&E), alcian blue, and PAS solution to determined histological change. Represent images were shown. Magnification was 200x.
