Effects of celecoxib a COX-2 inhibitor on postoperative abdominal adhesion in rats / 中华普通外科杂志

ABSTRACT

Objective To study the corelation between the expression of COX-2 and postoperative adhesions and to determine the effect of COX-2 selective inhibitor,Celecoxib,on postoperative adhesion formation. Methods Fifty SD rats were randomly assigned to five groups each consisting of 10 rats,Study groups were as follows(A)positive control group,(B)sodiumhyahronate group,(C)low dose Celecoxib group,(D)high dose Celecexib group,(E)negative control group,Five rats in each group were treated accordingly for consecutive 8 days and 15 days respectively and sacrificed,After treatment,intra-abdminal adhesions were scored using a standard method.The adhesions tissure and injured peritonaeum were subjected to Westem-blotting to detect the expression of COX-2. Results The level of postoperative adhesions and expression of COX-2 of sodiumhyahronate group、low dose Celecoxib group、high dose Celecoxib group were lower than that of positive control group(P<0.05),Sediumhyahronate treatment group was different formthe two Celecoxib treated groups(P<0.05).Conclusions Selective COX-2COX-2.mechanism,provides durable inhibition of intra-abdominal adhesions through an antiangiongenic COX-2 mechanism.
