Abstract:
Objective To investigate the effeets of ulimstatin on expression of intestinal defemin-5 mRNAin the rat model of sepsis.Method The experiment was performed in pharmaco-laboratory of medical college,Sun Yat-Sen University.sixty Sprague-Dawley rals were randomly divided into control,sepsis,pretreated andtreated groups(n=15).Semis was induced in the mts of latter three groups by cecal lifo.and puncture(CLP).The rats of pretreated group received 25 000 U/kg ulinastatin 2 hours before operation and the rats of uli-nastatin treated groups received 50 000 U/kg ulinastatin 2 hours after operation.Some pieces of ileum mucosa weretaken 12 h after CLP.Tge pathological changes were observed and the expression of RD-5 mRNA was detectedwith RT-PCR.All data were managed by SPSS 13.0 software and arIaIyzed by using One-way ANOVA and LSD-ttest.Results The expression of RD-5 mRNA in the rats of sepsis group significantly decreased compared to col-trol(P<0.05).The expression of RD-5 mRNA of pretreated and treated groups sigificantly inereased comparedto sepsis group(P<0.05);pretreated groups had more increased expression of,RD-5 mRNA compared to treatedgroups(P<0.05).Conclusions The expression of intestinal RD-5 mRNA significantly decreases in sepsis,which could be improved by the treatment of ulinadtatin leading to intestinal mucosal protection of the siqnifleant.The pretreatment may be more effective than the theTapeatic treatment in the rat model of sepsis.
