AIM To investigate the influence of Ligustrazine on cell apoptosis in rat kidneys with ischemia-reperfusion injury and the relationship between renal cell apoptosis and ischemia-reperfusion injury. METHODS The changes of plas-ma superoxide dismutase (SOD), malondialdehyde (MDA) and endothelin-1 (ET-1) as well as the influence of Ligustrazine on cell apoptosis were observed for 6 minutes 24 hours after the reperfusion in rat kidneys of ischemia. RESULTS The levels of plasma SOD, MDA and ET-1 in the Ligustrazine group were (103±18) KNU·L -1, (9.0±0.8) μmol·L -1 and (131±43) ng·L -1, respectively and those in the ischemia-reperfusion group were (88±14) KNU·L -1, (10.7±0.9) μmol·L -1 and (175±47) ng·L -1, respectively. The levels of SOD in the ligustrazine group were significantly higher than those in the ischemia reperfusion group (P<0.05), but the levels of plasma MDA and ET-1 were significantly lower than those in the ischemia-reperfusion group (P<0.05). The indexes of renal cell apoptosis in the ligustrazine group and the ischemia-reperfusion group were (5.75±3.02)% and (8.97±3.41)%, respectively and there was a significant difference between the two groups. CONCLUSION Ligustrazine reduces renal ischemia-reperfusion the injury and decreases indexes of renal cell apoptosis.
