Objective To observe the relationship between endoplasmic reticulum stress and ischemia acute renal injury. Methods The renal ischemia and reperfusion model was developed by bilateral clamping of the renal pedicle for 40 min and reperfusing for 1
6
12 and 24 h
respectively. Blood SCr and BUN were detected. Renal tubular injury was measured by PAS staining. The expression of ERS marker
GRP78 protein
in the ischemic renal tissue was detected by immunohistochemistry. Results Scr increased initially at I/R 1 h
reaching a peak at I/R 12 h
and decayed at I/R 24 h . The score of renal tubular injury increased at I/R 1 h
reaching a peak at I/R 12 h
and decayed at I/R 24 h. The expression of GRP78 protein reached the peak at I/R 6 h
maintaining a high level at I/R 12 h
and declined at I/R 24 h. The expression of GRP78 protein had positive correlation with renal tubular injury
and Scr. Conclusion ERS is started after renal I/R in rats. It may play an important role in AKI.
