The aim of this study was to investigate whether dexmedetomidine - administered before ischemia - has protective effects against lower extremity ischemia reperfusion injury that induced by clamping and subsequent declamping of infra-renal abdominal aorta in streptozotocin-induced diabetic rats. ⋯ We found that dexmedetomidine - 100 μg/kg intraperitoneally - administered 30 minutes before ischemia in diabetic rats ameliorates lipid peroxidation, oxidative stress, and I-R-related renal injury. We suggest that dexmedetomidine administration in diabetic rats before I/R has renoprotective effects.
