Effects of Jiuxieling Granules on Inflammatory Lesion of Colon Mucous Membrane in Rats with Ulcerative Colitis / 中国中医药信息杂志

ABSTRACT

Objective To observe the effects of Jiuxieling granules on rats with ulcerative colitis and explore its mechanism.Methods Ulcerative colitis models were established by immune method combined with local stimulation of 5% acetic acid.Wistar rats were randomly divided into control,model,positive control and low,middle,high dose Jiuxieling granules group.Rats in positive control group were treated with sulfasalazine,and those in three treatment groups were treated with low,middle and high dosage of Jiuxieling granules respectively for 14 days continuously.24 hours after last administration,the rats were killed to obtain colon mucous membrane to test GSH-Px,SOD,MDA,NO,tNOS and iNOS concentration of the homogenate of colon mucous membrane.Results Jiuxieling granules could markedly improve the levels of GSH-Px and SOD activity,whereas decrease the levels of MDA,NO,TNOS and iNOS.Conclusion Jiuxieling granules exert its marked curative effects on rats of ulcerative colonitis by resisting oxygen free radical lesion,inhibiting the generation of NO and NOS,and enhancing the activity of antioxidase.
