*The two experiments were undertaken using the same set of animals. NS + sham: saline plus sham group; Rb1 5 + sham: Rb1 5 mg/kg/h plus sham group; NS + I/R: saline plus I/R group; Rb1 2.5 + I/R: treatment with Rb1 at 2.5 mg/kg/h plus I/R group; Rb1 5 + I/R: treatment with Rb1 at 5 mg/kg/h plus I/R group; Rb1 7.5 + I/R: treatment with Rb1 at 7.5 mg/kg/h plus I/R group.
