Figure Lengend Snippet: V. parvula exacerbates colonic mucus barrier damage in DSS-induced colitis mice, while the MGQD ameliorates this V. parvula -exacerbated damage. (A,B) AB-PAS staining in mouse colon. (C) The IF staining of mouse colon for Muc2 (red) and DAPI (blue). Data are expressed as mean ± S.D. (n = 6). #P < 0.05, ##P < 0.01, ###P < 0.001 vs. the DSV group. *P < 0.05, **P < 0.01, ***P < 0.001 vs. the DSS group.

Figure Lengend Snippet: LPD improves colonic pathology (A) Serum LPS levels ( n = 8). (B) Morphological research measures include the number of goblet cells in the gland ( n = 3). (C) Representative pictures of HE staining, Scale bars, 100 μm. (D) Representative images of Ab-PAS staining, Scale bars, 100 μm. Data are presented as mean ± SEM ( n = 3–8 rats per group). For histological analyses, multiple sections and fields were averaged within each animal prior to statistical analysis. Statistical significance was determined by one-way ANOVA followed by Tukey’s post hoc test. ∗∗∗ p < 0.001.
