ABSTRACT

[Objective] To observe the curative effects and the influence of activity of Superoxide dismutase(SOD) and contents of Maleic dialdehyde(MDA) of Qingchangyukui Gel in Rats with Experimental Ulcerative Colitis. [Method]Ulcerative Colitis model was established in Wistar rats by injecting trinitro-benzene-sulfonic acid (TNBS)into anus, and then treated with Qingchangyukui Gel and salisy-lazosulfa-pyridine(SASP) respectively. Isolating the colon and measuring the SOD and MDA after treating for two weeks. [Results]Colon mucous membrane in the model group had serious erosion, ulcer, damaging of glandular organ, high inflammation grade; activity of SOD in model group was significantly lower than in normal group and contents of MDA increased. The other groups, especially in Qingchangyukui Gel group, had different levels of inflammation repairing, ulcer healing, increasing of SOD and reducing of MDA. [Conclusion]TNBS can cause Colon mucous membrane inflammation and ulcer, reducing of SOD and increasing of MDA , which are the typical pathological change of Ulcerative Colitis; the Qingchangyukui Gel has the effects of increasing the activity of SOD and reducing contents of MDA, therefore it can effectively treat the UC rat.
