Abstract: To explore the effect of erythropoietin(EPO)treatment on the expression of heme oxygenase-1(HO-1)mRNA in rats with globe ischemia-reperfusion injury. Methods The 4-vessel obstructive globe ischemic rat models were used in this study. The rats were randomly divided into three groups: the ischemia-reperfusion group, the experimental group and sham-operation group. Rats in the ischemiareperfusion group and the experimental group were subjected to EPO injection into the abdominal cavity after globe ischemia, however rats in the sham-operation group were not subjected to an operation. The expression of HO-1 mRNA was determined by RT-PCR. Results① After ischemia, the expression of HO1 mRMA was obviously changed based on time. ② The effect of EPO treatment on the expression of HO-1 mRNA in the cortex of this rat model was obvious. ConclusionThe protective effect of EPO for ischemiareperfusion injury is perhaps induced by up-regulating the expression of HO-1.
