Effect of LcS on exacerbated colitis in <i>Tcra</i>^-/- mice exposed to rWAS.

<p>(A) Colonic tissue weight. (B) Histological score of colitis. Each point represents an individual animal; horizontal bar with errors represents mean ± SE, n = 7 ~ 8 per group. (C) Corticosterone concentration in the serum. Data are presented as mean ± SE, n = 6 per group. control: <i>Tcra</i>^−/− mice not exposed to repeated water avoidance stress (rWAS), rWAS: <i>Tcra</i>^−/− mice exposed to rWAS. Mice were given placebo or LcS-fermented milk, which were denoted as ‘placebo’ or ‘LcS’. * p < 0.05, ** p < 0.01 (control + placebo vs. rWAS + placebo), ^# p < 0.05 (rWAS + placebo vs. rWAS + LcS).
