ABSTRACT
Objective To investigate the effects of vitamin E (VE) on renal ischemia/reperfusion (I/R) injury of rats.Methods A total of 18 male Wistar rats were randomly divided into sham-operated group,I/R group,VE + I/R group,and each group of 6 rats.All the animals were killed at the end of 24 h of reperfusion.Nephridial tissue were examined by light microscopy,and the level of blood urea nitrogen(BUN) and serum creatinine (SCr) were measured.The protein expressions of tumor necrosis factor α (TNF-α) were detected by Western blotting.Results Compared with sham-operated group,tubulointerstitial pathological injury in I/R group was significantly aggravated,which was shown by HE and PAS stain.Compared with I/R group,the degree of morphological changes as well as renal dysfunction in VE + I/R group were obviously lessened.Meanwhile,the levels of BUN,SCr in I/R group,VE + I/R group were (10.13 ± 2.14) mmol/L and (7.67 ± 1.63) mmol/L,(80.33 ±7.15) μmol/L and (63.67 ±5.40) μ mol/L,significantly higher than those in shamed-operated group ((3.85 ± 0.21) mmol/L,(48.67 ± 3.61) μmol/L;P < 0.05).And the level of BUN and SCr in VE + I/R group were significant lower than those in I/R group(P <0.05).Western Blotting showed that the protein expressions of TNF-α in VE + I/R group were obviously lower compared with those in group of I/R without VE treatment (P < 0.05).Conclusion Vitamin E can attenuate over-expressions of TNF-α in kidney following I/R,thus protect against structural damages and renal dysfunction in I/R rat models.
