Colonic tissue damage. Macroscopic damage scores were assessed using Wallace's colon macroscopic scoring system (31). Values are arithmetical means + SEM, $n=6-13$. Statistical significance was assessed using the Kruskal-Wallis test (K-W, differences between all groups of animals) and Mann-Whitney test (difference between group D and other groups of animals). *$P\le .05$, ***$P\le .001$. A, colitic animals fed with the combination of 0.4% thyme and 0.2% oregano oils; B, colitic animals fed with the combination of 0.2% thyme and 0.1% oregano oils; C, colitic animals fed with the combination of 0.1% thyme and 0.05% oregano oils; D, animals with TNBS-induced colitis; E, control sham animals.
