Abstract:
AIM: To investigate the effect of non-mitogenic human acidic fibroblast growth factor(nm-haFGF) on renal ischemia-reperfusion injury in rats.METHODS: Rat renal ischemia-reperfusion(I/R) injury was produced by removing the left kidney and subsequently clamping the right renal artery for 60 min followed by reperfusion for 24 h.5 min after reperfusion,different doses of nm-haFGF and haFGF(as positive control) were injected by lingual vein.24 h later,the samples of blood,urine and kidney were collected and the contents of malondialdehyde(MDA),blood urea nitrogen(BUN),creatinine(Cr) and superoxide dismutase(SOD) activity were detected.Histopathological changes were also observed.RESULTS: In the serum,SOD activity of all the nm-haFGF groups and the haFGF group increased significantly while the content of MDA decreased dramatically compared with the model group;The content of BUN and Cr also decreased wherever in serum or in urine;In renal tissue,SOD activity in nm-haFGF 20 ?g/kg group,40 ?g/kg group and haFGF group rose significantly compared with the model group,while MDA decreased dramatically.Histological examination showed that nm-haFGF markedly attenuates the renal edema,brush border's defluvium and cell necrosis induced by ischemia-reperfusion.CONCLUSION: nm-haFDF could resist the renal injury induced by ischemia-reperfusion in rats.
