Histological photographs of H&E stained colon after 2-week treatments (100×). TNBS-induced rats had severe colitis with deep ulceration, transmural leukocyte infiltration, loss of goblet cells, and thickening of intestinal walls. Different treatments relieved colitis in various degrees. Sulfasalazine and mesalazine + allicin made the colons basically normal.
