Abstract: | ObjectiveTo evaluate the effect of decoction prepared with Yang-activating and stasis-eliminating medicinals from Traditional Chinese Medicine (TCM) on the intestinal mucosal permeability in rats with ulcerative colitis induced by dextran sulfate sodium (DSS).MethodsTotally 55 male Wistar rats (body weight of 170–190 g) were randomly divided into the blank group (n = 10) and the model duplication group (n = 45). The blank group was not intervened, while the other was modeled with 5% dextran sulfate sodium by gavaging in a dosage of 4 mL per day to induce ulcerative colitis, a total of 7 days. Then, the model rats were divided into model blank group, mesalazine group and TCM group, and each group was consisted of 15 rats. They were given retention enema 10 min with normal saline, mesalazine enema (0.036 g/mL), and Yang-activating and stasis-eliminating decoction [0.54 g/mL of a decoction boiled by Puhuang (Pollen Typhae), Xiebai (Bulbus Allii Macrostemonis) and Wulingzhi (Faeces Trogopteri)] for 10 days respectively. Afterwards, all of the rats were evaluated by disease activity index (DAI), histological changes of distal colon, expression of occludin protein and ultrastructure of intestinal epithelial cells. Furthermore, ratio of lactulose to mannitol (L/M) discharged in urine was evaluated.ResultsComparing the results between TCM and model control groups, scores of DAI and histological lesions decreased significantly (P = 0.000 < 0.01), ultrastructures of intestinal epithelial cells and tight junctions were more complete. The expression of occludin protein (P = 0.001 < 0.01) increased while the L/M value decreased significantly (P = 0.000 < 0.01) in TCM group. There was no statistical difference between the TCM and mesalazine groups in results of each item (P > 0.05).ConclusionThe decoction prepared with Yang-activating and stasis-eliminating TCM medicianls can restore intestinal mucosal epithelial cells and tight junctions the model rats with ulcerative colitis; it can reduce histological lesions and protect the permeability of intestinal mucosa barrier in the rats as well. |
