Postconditioning is an effective strategy to reduce renal ischaemia/reperfusion injury

Abstract

BUN and creatinine significantly decreased in the postconditioning group as compared to control rats. Mitochondrial respiratory function was significantly impaired in control rats, mainly at the level of Complex II. Postconditioning significantly reduced this mitochondria impairment. The rate of mitochondrial peroxide production was higher in the control group than in the protected group at the end of postconditioning reperfusion. Moreover, mitochondrial protein oxidation was significantly higher in control rats than in the postconditioning group at the end of reperfusion. Conclusions. In the present study, postconditioning reduced renal functional injury and reduces mitochondria respiratory chain impairment, mitochondria peroxide production and protein damage.
