Examination of the Anti-Inflammatory, Antioxidant, and Xenobiotic-Inducing Potential of Broccoli Extract and Various Essential Oils during a Mild DSS-Induced Colitis in Rats

Table 8

Effects of feeding broccoli extract and various essential oils on relative mRNA expression of various pro- and anti-inflammatory parameters in colon of DSS-treated rats compared to an untreated control. Values are means ± SEM and represent relative mRNA concentrations as 𝑛-fold of group Con = 1. Different small letters in a row indicate significant differences between means (𝑃 ≤ 0.05). 𝑛=4 in phase 1, 𝑛=6 in phase 2 and phase 3.
