ABSTRACT
AIM:
To detect the changes of heme oxygenase-1 (HO-1) expression in kidney following ischemia-reperfusion of hindlimbs and to elucidate their significance.METHODS:
Health SD rats were randomly divided into normal (N), sham (S), 4h ischemia without reperfusion (I), 4 h ischemia-2, 6, 12, 18 or 24 h reperfusion (I-R) groups and I-R18h+zinc protoporphyrin (ZnPP) group. I-R was established using the occlusion for 4 h and re-opening for 2-24 h of the femoral arteries. In I-R 18 h+ZnPP group, ZnPP (5 ?mol?kg~(-1) body weight) was intravenously injected 6 h and 12 h after reperfusion, respectively. The expression of HO-1 mRNA in kidney was detected with reverse transcription-polymerase chain reaction (RT-PCR). The expression and location of HO-1 protein were detected with immunohistochemical technique. The observation of pathologic changes of kidney was made following the inhibition of HO-1 by ZnPP.RESULTS:
The relative expression level of HO-1 mRNA significantly increased in I-R group, compared to those in the control groups, It was maximal in I-R 18 h group, and thereafter expression level of HO-1 mRNA decreased, however significant expression was still detected in I-R 24 h group (P
