title: [Effects of YM injection on oxidative stress injury in renal warm ischemia/reperfusion].
abstract: OBJECTIVE
  This study was undertaken to determine whether YM injection would attenuate warm I/R injury in mice.
  
  
  METHODS
  Renal warm I/R was induced in C57BL/6 males, and the mice were sacrificed 24 hours post-reperfusion. YM was given intraperitoneally 12 hours and 30 min before I/R. The effects of YM on oxidative stress and proinflammatory mediators caused by renal I/R injury were assayed.
  
  
  RESULTS
  Renal I/R caused severe injuries in the kidneys of mice. In the presence of YM at doses of 5, 15 and 25 mg/kg, the kidney malondialdehyde (MDA) content reduced by 16.6%, 25.0% and 35.5% respectively, and the kidney superoxide dismutase (SOD) activities were elevated by about 38.7%, 48.3% and 76.1% respectively. ICAM-1 expression was dramatically suppressed in the presence of YM (25 mg/kg).
  
  
  CONCLUSIONS
  YM attenuates the renal warm I/R injury at least partially via decreasing the neutrophils infiltration and suppressing the over-expression of adhesion molecules.
