Body weight changes. Changes in body weight are expressed as a percentage of the original weight on day 0. Values are arithmetical means ± SEM. Statistical significance of the differences between the group of untreated colitic animals (TNBS group) and other groups of animals was assessed using the Student $t$ test;*$P\le .05$, **$P\le .01$, ***$P\le .001$. 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; a: statistical difference between the D and E groups; b: statistical difference between the D and B groups.
