Abstract:
Objective To investigate the effect of adenosine on rats with acute renal failure(ARF) resulting from ischemia-reperfusion(IR).Methods The model of renal IR injury rats was induced by nipping bilateral renal pedicels of rats with non-traumatic forceps for 40 minutes.The first adenosine group was given adenosine 10 mg/kg intraabdominally at 2 hours before IR.The second adenosine group was given the same adenosine at 40 minutes after IR.Serum creatinine(Scr) levels,the proportion of apoptosis of renal tubular cells(RTCs) and the pathological changes of renal tissue were observed separately in every group at 2,6,12 hours after IR.Results 1.At 12 hours after IR,in IR group Scr levels and apoptosis of RTCs count were(198.56?13.35) ?mol/L and 26.50?2.07,which were increased significantly compared with sham group.In the first and second adenosine groups,they were(113.85?(12.90) ?mol/L),14.67?3.44 and(218.79?37.65) ?mol/L,20.83?5.27,respectively,and all of them were higher than those in sham group(all P0.05).Conclusions Adenosine which is given to rats with IR before IR may be an effective pharmacological agent for prevention and treatment of renal IR injury.The mechanism may be relevant to saving energy and reducing cellular apoptosis.
