Antinociception by spinal and systemic oxycodone: why does the route make a difference? In vitro and in vivo studies in rats.

abstract：BACKGROUND:The role of endothelial nitric oxide synthase (eNOS) in isoflurane postconditioning (IsoPC)-elicited cardioprotection is poorly understood. The authors addressed this issue using eNOS mice. METHODS:In vivo or Langendorff-perfused mouse hearts underwent 30 min of ischemia followed by 2 h of reperfusion in th...
