| Abstract: | Aim:To elucidate the effect of tetrandrine on acute ischemic renal injury and the relation between tetrandrine and apoptosis.Methods:A model for bilateral post-ischemic renal injury in rats was developed by calmping renal pedicles for 45 minutes,renal tissular DNA fragmentation analysis and renal tissular HE staining were used.Also the quantative analysis of apoptosis in injuried renal tubular epithelial was carried out by using TdT mediated dUTP nick and labeling (TUNEL).Results:Apoptosis of renal tubular epithelial increased in acute ischemic renal injury.Tetrandrine can remarkably decrease the level of apoptosis in injuried renal tubule while protecting renal tissue against the ischemic injuries.Conclusion:Tetrandrine can adjust the level of apoptosis in renal tubular epithelial and alleviate renal tissular injury. |
