Methods: The mice were divided into 4 groups: ethanol control group, TNBS model group, baicalin low-dose group and baicalin high-dose group. The model of experimental colitis in mice was induced by TNBS enema. After 2 hours of TNBS enema, baicalin was given by gavage, QD × 7D. The animals were sacrificed on the 8th day to observe the extent of colonic mucosal damage, and the Peroxidase activity, Malondialdehyde (MDA) and glutathione (GSH) contents were measured. Results: Compared with the TNBS model group, the body weight, gross injury score and histological changes were significantly improved;MPO enzyme activity and MDA content were significantly decreased in the low and high-dose baicalin groups;and the content of glutathione increased. Conclusion: Baicalin can alleviate TNBS-induced colitis in mice, and the mechanism is related to the antioxidation of baicalin.展开更多
