ABSTRACT
Objective To observe the protective effect of rhein-arginine (RhA) on rats ankylenteron and to explore the anti-inflammatory mechanism. Methods Sixty male SD rats were randomly divided into 6 groupsnormal control group,model group,dexamethasone group (in the dose of 10 mg?kg-1) and low-,medium-and high-dose RhA groups (in the dose of 7.5 mg?kg-1,15 mg?kg-1,30 mg?kg-1 respectively). Except that the normal control group,the rats in other groups were induced ankylenteron. Intraperitoneal injection of saline was administered to the rats in the normal control group and the model group,and dexamethasone group and RhA groups were given the corresponding drugs according to the experimental design. The treatment lasted 7 days. On the 8th day after surgery the blood samples of each group were collected. The levels of interleukin-1?(IL-1?),interleukin-4(IL-4)and tumor necrosis factor-?(TNF-a)were determined by enzyme linked immunosorbent assay. Grades of ntestinal adhesion were ranked by macroscopic observation. The adhesive tissues between cecum and abdominal wall were taken for pathological observation and the determination of hydroxyproline (Hyp) content. Results RhA significantly relieved the experimental intestinal adhesion,Obviously decreased the levels of IL-1?and TNF-?,and inhibited the hyperplasia of fibrous connective tissue. However,there was no significant impact on the level of IL-4. Conclusion RhA can effectively prevent the information of postoperative ankylenteron by inhibiting the expression of inflammatory cytokines and reducing the inflammatory response.
