Abstract:
Objective To observe the injury to the heart,liver and kidney induced by hind limb ischemia/reperfusion(I/R),and to study the protective effect of H2S by attenuating this injury,in order to offer a theoretical basis for therapeutic application.Methods A model of hind limb I/R was reproduced.28 rats were divided randomly into 4 groups:normal control group(C,n=8),ischemia 4h group(I,n=8),ischemia 4h and reperfusion 4h group(I/R,n=6)and I/R+NaHS group(n=6)(NaHS can provide H2S for rats in vivo).The concentrations of CK,CK-MB,Tn-T,ALT,AST,Cr and urea in blood plasma were determined.The pathological changes in the heart,liver and kidney were observed with HE staining.Results The concentration of CK,CK-MB and Tn-T in I group increased significantly compared with that in C group,and that in I/R group was higher than in I group.No significant difference was found in plasma concentration of ALT,AST,Cr and Ur between C group and I group,while it they were increased significantly in I/R group compared with that in I group,and that in I/R+NaHS group were decreased significantly compared with that in I/R group.Pathological examination revealed pathological findings of injury to the heart,liver and kidney in I group,and even more serious injuries were found in I/R group than in I group,while the they were less marked in IR+NaHS group compared with that in I/R group.Conclusion Hind limb ischemia/reperfusion may result in injury to the heart,liver and kidney.H2S may attenuate injury to remote organs follawing hind limb ischemia/reperfusion.
