Objective: To observe the effects of Huixiang Zhizhu soup（HX-S） on superoxide dismutase（SOD）

malondialde hyde（MDA） and pathomorphology in rats with adhesive intestinal obstruction

and provide experimental evidence for the realitionship of SOD

MDA and pathomorphology change with the adhesive intestinal obstruction of HX-S.Method:The Wister rat model of adhesive intestinal obstruction.One hundred and eight rats were randomly divided into the normal group

model group

Dachengqi soup（DS） group

HX-S low dosage（HX-SL）group

HX-S middle dosage（HX-SM）group and HX-S high dosage（HX-SH）group.Succeed in the model.The rats were killed after three days

five days and seven days adopt the intestine tissue to

with 6 rats in each subgroup.The levels of SOD and MDA in intestine tissue were determined by radioimmunoassay

adopt the intestine tissue to observe the change of pathomorphology.Result: Compared with those in normal group

the level of intestine tissue SOD were decreased obviously

and the level of intestine tissue MDA were increased obviously in model group（P < 0.05）;Compared with those in model group

the level of intestine tissue SOD were increasedobviously

and the level of intestine tissue MDA were decreased obviously（P < 0.05） and pathomorphology investigation small intestine injury had been restored in model group in DS group

HX-SL group

HX-SM group and HX-SH group.Conclusion: HX-S has good action effect in rats with adhesive intestinal obstruction

and its mechanism may be correlated with anti-intestine tissue peroxidation.
