Abstract:
Objective To investigate the immunomodulatory effect of mare's milk on dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) mice. Methods Kunming mice were randomly divided into a blank group(0.8 mL/day saline by gavage) and a DSS modeling group. After modeling, the DSS modeling group was further divided into a control group (0.8 mL/day saline), a salazosulfapyridine (SASP) treated group(430 mg/(kg.d)) and a mare's milk group(0.8 mL/day), with 16 mice in each group. After 10 days of gavage administration, HE staining was performed to observe colonic inflammation, and the disease activity index (DAI) and colonic mucosal damage index (CMDI) were scored. ELISA was used to determine the levels of interleukin 1β (IL-1β), IL-6, and IL-10 in mouse colonic tissues, and flow cytometry was used to detect the percentages of CD4+ and CD8+ T lymphocytes in peripheral blood. Results Compared to the blank group, all indexes in mice of the control group indicated that DSS successfully induced UC. Compared to the control group, colon shortening in UC mice was attenuated in the mare's milk group; inflammation and ulcer formation in colonic tissues were inhibited; DAI and CMDI scores were lowere; IL-1β and IL-6 levels in mouse colonic tissues were significantly reduced; IL-10 levels were increased and the CD4+/CD8+ T cell ratio was reduced. Conclusion Mare's milk can inhibit the inflammation of DSS-induced UC mice through immune regulation.
