Abstract:
Objective:To determine the effect of urinary trypsin inhibitor(UTI)on protease activity in the colonic tissues of ulcerative colitis(UC) rats.Methods:The experimental UC was induced in Wistar rats by enema with 0.25ml of 18% 2,4-dinitrobenzenesulfonic acid (DNBS) dissolved in ethanol.UTI was injected into the rats through the caudal vein.Protease activity present in colonic tissues was determined on gelatin zymograms.Results:The protease activity which presented in colonic tissues of the group treated with UTI was only 1/3 that of the control.Conclusion:The protease activity decreased significantly after we treated the rats with UTI.
