To observe the effect of probiotics on intestinal health in a model of high-salt diet (HSD, 8%) treated mice for 49 days. Cinical (body weight, colon length and colon weight) and historical changes were evaluated. In addition, colon levels of interleukin-1β, IL-6, IL-18, IL-17A, tumor necrosis factor (TNF)-α were detected by enzyme-linked immunosorbent assay. Relative to the HSD model group, the mice in the probiotics treatment group increased in body weight, colon length, and the ratio of colon weight to length was significantly lower (P<0.05). The DAI index of mice in the intervention group was lower than that in the HSD model group (P<0.05). Histological observation also found that the intervention of probiotics is able to reduce the infiltration of inflammatory cells in colon tissue induced by HSD. The results of Masson staining suggest that the intervention of probiotics also reduces the occurrence of intestinal fibrosis in mice with colitis. Our results suggested that probiotics with an activity to improve intestinal health and reduced inflammation in HSD treated mice.
